BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring control system for controlling a load as a predetermined control signal transmitted by a time division multiplex transmission system, and an interface device for use in a remote monitoring control system.

In response to a switch operation of an operation terminal to which a plurality of control terminals for controlling load are uniquely identified, the control signal containing control data is controlled by a multiplex transmission method. By transmitting, the remote monitoring control system which performs remote control (remote monitoring control) which controls the load connected to the control terminal is devised (for example, refer patent document 1).

This remote monitoring control system is a lighting control system which can centrally control a plurality of lighting apparatuses that are loads provided in a large space such as a store, a factory, a warehouse, or the like. Such a lighting control system is a high user convenience control system which can remotely operate a plurality of lighting fixtures by a wireless transmitter, or collectively control lighting and non-lighting of a plurality of lighting fixtures.

In such a control system, there is disclosed a method capable of executing forced control of controlling a specific load in preference to another terminal in an emergency such as when a power failure or fire occurs (see Patent Document 2, for example). Thus, for example, by forcibly controlling the lighting device of the evacuation path to light up or blink in an emergency, people in the building or the like can be surely guided to a safe place.

Moreover, the method which connected the forced pattern holding | maintenance unit 101 of the contact input system as shown in FIG. 7 to the signal line Ls of a remote monitoring control system is also implemented and implement | achieves this forced control with a very simple structure. .

The forced pattern holding unit 101 shown in FIG. 7 includes a plurality of physically finite contact input terminals, and integrates the local system 100 in response to the contact being turned on by, for example, detection by a sensor. A forced control signal for requesting the transition to the forced control state is output to the transmitting unit 102 that controls the target.

The transmission unit 102 that receives the forced control signal from the forced pattern holding unit 101 controls the local system 100 as a control pattern corresponding to the contact input terminal in the on state, and at the same time, loads from the switch terminal. Force control to block any operation request to the device.

(Patent Document 2) Japanese Patent Application Laid-Open No. 7-336776

Thus, the forced pattern holding unit 101 shown in FIG. 7 can realize forced control with respect to the remote monitoring control system while having a very simple configuration. However, this forced pattern holding unit 101 has a problem in that flexibility in construction design and system design is insufficient because it is a contact input method.

The contact input terminals serving as triggers for shifting to the forced control state possessed by the forced pattern holding unit 101 each have a priority, and, for example, when a plurality of contact input terminals are turned on at the same time, according to this priority. The control pattern is executed. Therefore, when the forced pattern holding unit 101 is used, it is necessary to perform wiring with the local system 100 in accordance with the level of the forced control state, which requires a lot of effort and cost for construction. .

In addition, since the contact input terminal included in the forced pattern holding unit 101 is a physical terminal, the number of levels of the forced control state that can be set is also limited. Therefore, it is impossible to realize the setting of the forced control state in various scenes, such as when the forced control state is to be in a forced control state during an emergency such as a fire or a disaster, or when only a limited area is required to be in a forced control state. There is a problem.

In addition, since the forced pattern holding unit 101 is a contact input method, there is a problem that it cannot be transferred to the forced control state in response to input from a plurality of places (for example, three-way wiring).

Best Mode for Carrying Out the Invention Embodiments of the present invention will be described below with reference to the drawings.

(Example 1)

With reference to FIG. 1, the remote monitoring control system shown as Embodiment 1 of this invention is demonstrated. As shown in FIG. 1, in the remote monitoring control system, a transmission unit 10, a plurality of multiple transmission switch terminals 11, and a lighting device 13 serving as a load are connected to control a plurality of loads. The relay terminal 12 (with a terminal unit), the load outlet outlet 15 are connected, and the outlet control unit 14 which controls this load, and the interface device 20 are connected via a two-wire signal line Ls. It is.

The outlet control unit 14 is configured to enable the supply of commercial power to the on state of the outlet 15, that is, the connected external device, and to block the supply of commercial power to the off state, that is, the connected external device. The remote control breaker 14B which switches a state, and the breaker control terminal unit (T / U) 14A which controls this remote control breaker 14B are provided.

Such a remote monitoring control system realizes desired control of a load by transmitting a signal having a format as described below. In addition, in order to avoid the verbosity of description, in description of this format signal, it demonstrates using the multiple transfer switch terminal 11 and the relay terminal 12. As shown in FIG.

The transmission unit 10 transmits the transmission signal Vs of the format shown to Fig.2 (a) with respect to the signal line Ls. As shown in Fig. 2A, the transmission signal Vs includes a start pulse ST indicating the start of signal transmission, mode data MD indicating the mode of the signal, and an address for individually recognizing each terminal. Data AD, control data CD for controlling a load of the lighting fixture 13, etc., checksum data CS for detecting a transmission error, and a time slot for receiving a carrier signal (monitoring data) from each terminal. It is a time-division multiplexing signal of bipolarity (± 24 V) consisting of a signal carrier period (WT). The transmission signal Vs of this format is modulated by pulse width modulation and transmitted as shown in Fig. 2B.

When the address data AD included in the transmission signal Vs received via the signal line Ls coincides with its own address, the multiple transmission switch terminal 11 and the relay terminal 12 transmit the transmission signal Vs. Control data (CD) is inputted and the monitoring data is short-circuited between the current mode signal (signal line Ls) via an appropriate low impedance in synchronization with the signal transfer period (WT) of the transmission signal (Vs). Signal).

The transfer unit 10 includes a dummy signal transmitter and an interrupt processor, which are not shown. The dummy signal transmitter executes regular polling to always transmit the transmission signal Vs in which the address data AD is cycled using the mode data MD as the dummy mode. On the other hand, when the interrupt processing unit generates the interrupt signal Vi as shown in Fig. 2C from the multiple transfer switch terminal 11 in synchronization with the start pulse ST of the transfer signal Vs in the dummy mode, The interrupt signal Vi is accessed to the generated multiple transfer switch terminal 11 to return the monitoring data.

The transmission unit 10 generates control data CD to the relay terminal 12 which controls the corresponding load based on the returned monitoring data, and further transmits the control data CD to the signal line Ls. By time-division multiplexing via the control, the light-off and lighting of the lighting fixture 13 which is a desired load are controlled.

For example, when the operation switch 11a of the multiple transfer switch terminal 11 is operated or turned off, the interrupt signal Vi is sent out to the signal line Ls.

The transfer unit 10 transmits a transfer signal Vs for searching the address of the multiple transfer switch terminal 11 which interrupted in response to this interrupt signal Vi. The interrupted multiple transfer switch terminal 11, when accessed by the transfer unit 10, returns its own unique address as monitoring data.

The transfer unit 10 which has received this monitoring data determines the interrupted multiple transfer switch terminal 11 and then transfers the signal Vs having the address data AD of the multiple transfer switch terminal 11. Is sent to perform access, and the operation data according to the operation of the operation switch 11a and the address data assigned to the operation switch 11a are returned as monitoring data.

The transfer unit 10 generates the control data CD based on the operation data of the multiple transfer switch terminal 11 conveyed as the monitoring data, and also previously based on the address data conveyed as the monitoring data. With reference to the table stored corresponding to this address data, address data AD for sending control data CD to the relay terminal 12 connected to the lighting fixture 13 to be controlled is obtained.

The transmission unit 10 time-division-multiplexes the transmission signal Vs including the control data CD thus generated and the acquired address data AD via the signal line Ls. The relay terminal 12 specified in the address data AD of the transmission signal Vs is similarly designated by the operation of the multiple transfer switch terminal 11 based on the control data CD of the transmission signal Vs. The lighting fixture 13 is turned on and off.

In addition, the control of switching the on state and the off state of the outlet 15 by the outlet control unit 14 connected to the signal line Ls also has the same operation.

(Interface device 20)

As shown in FIG. 1, the interface device 20 connected to the signal line Ls is a communication network network 25 in which wiring topology is free, in addition to the transmission signal terminal 21 which is a connection interface with the signal line Ls. ), For example, a communication interface 22 with an Ethernet (registered trademark) or a LON (Local 0perating Network (registered trademark)) and data communication with the external device 26 as a predetermined communication protocol according to the communication network 25. can do. This external device 26 functions as a host device (host) of the remote monitoring control system connected via the interface device 20.

The interface device 20 generates a forced control request signal for requesting the remote monitoring control system to transition to a forced control state in response to a command request from an external device 26 connected via a communication network network, and transmits a signal line Ls. It transmits to the transmission unit 10 via the said. The forced control request signal transmitted from the interface device 20 to the transmission unit 10 is a signal that becomes a trigger for bringing the remote monitoring control system into the forced control state.

The transmission unit 10 which received this forced control request signal first controls the load of a remote monitoring control system by the control pattern according to the level of the forced control state contained in a forced control request signal. The external device 26 inputs a control pattern indicating which forced control state to make as a command request when the remote monitoring control system is put into a forced control state.

When the transfer unit 10 controls each load connected to the signal line Ls as a control pattern included in the forced control request signal, it invalidates the operation input of the multiple transfer switch terminal 11, that is, the multiple transfer switch terminal ( Even if 11) is operated, the load control cannot be performed to complete the transition to the forced control state.

For example, in case of an emergency such as a fire or earthquake, the lighting fixture 13 is turned on or flashed, and power saving is performed in accordance with switching to self-power generation (GC power supply) to supply power to unnecessary points. A control pattern for stopping the operation is used, and after the lighting device 13 is controlled by this control pattern, the safety input is ensured by making the operation input of the multiple transfer switch terminal 11 invalidate (forced control state). .

Moreover, in a store etc., the control pattern which made the lighting fixture 13 of a sales floor light is used, and after the lighting fixture 13 is controlled by this control pattern, the operation input of the multiple transfer switch terminal 11 is invalidated. By setting it as the state (forced control state), it is made to prevent the badness about the lighting in the sales floor during business hours.

The external device 26 may also input, to the interface device 20, a command request for transmitting a release request signal for releasing the forced control state of the remote monitoring control system once put into the forced control state. According to this, the interface device 20 transmits the release request signal to the transmission unit 10 via the signal line Ls, thereby releasing the forced control state of the remote monitoring control system by the transmission unit 10.

In addition, the interface device 20 detects an abnormal state of the remote monitoring control system connected to the signal line Ls by the transmission signal terminal 21, for example, stopping the transmission signal, shorting or disconnection of the signal line Ls, and the like. When it has a function which always monitors and there is an abnormal state and control is difficult, it can be notified according to the instruction from the external device 26 in the host apparatus connected via the communication network 25. FIG. Thereby, the external device 26 can determine beforehand the control content and control to be performed as needed from the state of the remote monitoring control system which is a local system. In addition, since the connection interface 22 included in the interface device 20 is an interface that can be connected to the communication network network 25 free of wiring topologies, a configuration including a plurality of external devices 26 included in such a host device is provided. It can also be easily constructed.

Since the central monitoring device which collectively monitors air conditioning control, power control, lighting control, etc. in a large-scale facility also monitors and controls local systems other than the remote monitoring control system, which is a local system that performs lighting control as shown in FIG. If all of them can be built on the same communication network, the system design becomes easy. As described above, since the connection interface 22 included in the interface device 20 is an interface that can be connected to the communication network network 25 free of wiring topology, the central device monitors the external device 26 in the host device. The device also facilitates system design of a local system that executes lighting control for the remote monitoring control system via the interface device 20.

The interface device 20 also functions as a web server that can set various conditions for the external device 26 in the host device to execute forced control using the web screen as an interface.

(Effect of Example 1)

Thus, the remote monitoring control system shown as Example 1 of this invention is connected with the signal line Ls, and is provided by the interface apparatus 20 provided with the connection interface 22 which connects with the communication network 25, In response to a command request from the external device 26, a forced control request signal for requesting the transition to the forced control state of the remote monitoring control system is transmitted to the transmission unit 10.

Thereby, the transmission unit 10 controls the lighting fixture 13 or the outlet 15 which is a load according to the control pattern of the forced control request signal, and then invalidates the operation input from the multiple transfer switch terminal 11. Transfer to the forced control state.

Accordingly, the interface device 20 transmits a forced control request signal for transitioning to forced control in various control patterns according to a command request from the external device 26 via the communication network 25 without being physically restricted. By transmitting to the unit 10, the remote monitoring control system can be shifted to the forced control state.

In addition, since the interface device 20 also facilitates control by the external device 26 via the Internet line, the remote monitoring control system provided in the wallpaper can be controlled from the external device 26 located at a remote location.

(Example 2)

Next, the remote monitoring control system shown as Embodiment 2 of this invention is demonstrated using FIG. In addition, in the remote monitoring control system shown as Example 2, the same code | symbol is attached | subjected about the part which overlaps with the remote monitoring control system shown as Example 1 mentioned above, and description is abbreviate | omitted.

As for the remote monitoring control system shown as Example 2, the transmission unit 10, the several multiple transmission switch terminal 11, and the lighting fixture 13 which is a load are connected, and the some relay terminal (controlling this load ( 12) (with a terminal unit), an outlet 15 serving as a load is connected, and an outlet control unit 14 for controlling the load, and the interface device 30 are connected via a two-wire signal line Ls.

This remote monitoring control system realizes the desired control of the load by transmitting a signal of the format described with reference to FIG.

(Interface device 30)

The interface device 30 shown in FIG. 3 has a schedule timer that can set a predetermined time schedule. The interface device 30 transmits a forced control request signal to the transmission unit 10 via the signal line Ls requesting the remote monitoring control system to transition to the forced control state based on the time schedule set in this schedule timer. do.

In addition, as shown in FIG. 3, the interface device 30 connected to the signal line Ls can be connected to an external device 35 in addition to the transmission signal terminal 31 which is a connection interface with the signal line Ls. Equipped with 32. The connection interface 32 is another interface for connection between devices, for example, a connection topology with a communication network network of Ethernet (registered trademark) or LON (Local 0perating Network (registered trademark)) free of wiring topology. Possible interfaces are also good.

In this way, the external device 35 connected to the interface device 30 via the connection interface 32 can set a time schedule for setting a timing for transmitting the forced control request signal to the schedule timer of the interface device 30. have. The time schedule can also set the transmission timing of the release request signal for releasing the forced control state of the remote monitoring control system once referred to as the forced control state.

For example, during the business hours in a store or the like, the load of the remote monitoring and control system can be prevented so as to prevent operation of a wall switch by a person other than the person concerned or to prevent the lighting apparatus 13 in the store from turning off in response to a certain sensor response. After controlling with the control pattern, the control mode is set to forced control.

The interface device 30 also functions as a web server in which the external device 35 in the host device can set various conditions for executing forced control using the web screen as an interface.

(Effect of Example 2)

As described above, the remote monitoring control system according to the second embodiment of the present invention uses the schedule timer included in the interface device 30 connected to the signal line Ls to perform the transition to the forced control state of the remote monitoring control system. The required forced control request signal is automatically transmitted to the transmission unit 10 at a preset time schedule.

Accordingly, the transmission unit 10 controls the lighting device 13 or the outlet 15 serving as the load according to the control pattern of the forced control request signal, and then invalidates the operation input from the multiple transfer switch terminal 11. Transfer to the forced control state.

Therefore, the interface device 30 can autonomously control the transmission of the forced control request signal, which is a trigger for transitioning the remote monitoring control system to the forced control state, once the time schedule is set for the schedule timer. The user's convenience can be greatly improved. In addition, control by the remote monitoring control system alone, which is a local system, becomes easy.

(Example 3)

Next, the remote monitoring control system shown as Embodiment 3 of this invention is demonstrated using FIG. In addition, in the remote monitoring control system shown as Example 3, the same code | symbol is attached | subjected about the location which overlaps with the remote monitoring control system shown as Example 1 mentioned above, and description is abbreviate | omitted.

In the remote monitoring control system shown as the third embodiment, a plurality of relay terminals (not shown) are connected to a transmission unit 10, a plurality of multiple transmission switch terminals 11, and a lighting device 13 serving as a load. 12) (with a terminal unit), an outlet 15 serving as a load is connected, and an outlet control unit 14 for controlling the load, and the interface device 40 are connected via a two-wire signal line Ls.

This remote monitoring control system realizes the desired control of the load by transmitting a signal of the format described with reference to FIG.

(Interface device 40)

As shown in Fig. 4, the interface device 40 connected to the signal line Ls is a connection interface for realizing connection between devices with the transmission signal terminal 41, which is a connection interface with the signal line Ls, and the external device 45 ( In addition to 42, a connection interface 43 connected to a plurality of weighing terminals 44 via a communication line Lt is provided.

The weighing terminal 44 is a terminal for weighing all values related to the operation state of the remote monitoring control system, for example, a remote control breaker 14B measured by the current sensor CT as shown in FIG. 4, The electric power of the remote control breaker 14B is measured using the current value between the outlets 15. The metering terminal 44 transmits the acquired metering value, for example, the amount of power used by the remote control breaker 14B to the interface device 40 via the communication line Lt as the metering value information in the example shown in FIG. 4. do.

The interface device 40 compares the weighing value information transmitted from the weighing terminal 44 with a preset threshold value, and forces the remote monitoring control system to request the transition to the forced control state based on the comparison result. The control request signal is transmitted to the transmission unit 10 via the signal line Ls. The interface device 40 may also transmit a release request signal for releasing the forced control state of the remote monitoring control system once put into the forced control state depending on the comparison result of the measured value information and the threshold value.

For example, the interface device 40 transmits a forced control request signal when the measured value information matches or exceeds the preset threshold value, and on the contrary, transmits a release request signal when the measured value information falls below the threshold value. do. In addition, the interface device 40 may switch the level of the forced control state to be shifted in accordance with the value of the acquired metering information.

The weighing value information transmitted from the weighing terminal 44 to the interface device 40 may be any value as long as it is a value which affects the operation state of the remote monitoring control system. For example, when the remote monitoring control system is one of the local systems monitored by the central monitoring control device, and the remote monitoring control system is operated by a common power supply, the interface device 40 may determine the central monitoring control device. Measurement value information obtained by measuring the amount of power on the main line by the measurement terminal 44 is obtained. The interface device 40 compares the acquired measured value information with a threshold set in advance as an upper limit of the amount of power used, and issues a forced control request signal to put the remote monitoring control system into a forced control state when the threshold is reached. Send. By the transmission unit 10 having received this forced control request signal, the remote monitoring control system can prevent the power consumption from being transferred to the forced control state.

In general, when the capacity of the weekly breaker is smaller than the sum of the capacity of the lower branch breakers, even if the used capacity of each branch breaker is within the rating, when the total use capacity of the branch breakers increases, the weekly breaker falls off. There is.

Therefore, the amount of power on the main line is measured and monitored by the weighing terminal 44 at an interval in which the upper limit of the amount of electric power used based on the capacity of the weekly breaker in the interface device 40 is set as a threshold, and the threshold value is reached. The forced control request signal is transmitted to the transmission unit 10 to shift to the forced control state at the time point. As a result, the on-control request cannot be made to the branch breaker control terminal, so that it is possible to prevent the power consumption exceeding the capacity of the weekly breaker. Therefore, it can avoid in advance that a daytime breaker falls and turns off.

The interface device 40 limits the amount of power used under the branch circuit breaker in addition to requiring the transition to the forced control state as described above by using the result of the comparison between the preset threshold value and the weighing terminal 44. It may also notify that it is no longer available.

As shown in FIG. 4, the interface device 40 connected to the signal line Ls is connected to the external device 45 in addition to the transmission signal terminal 41 which is a connection interface with the signal line Ls. Equipped) As this connection interface 42, another interface which is an interface for inter-device connection, for example, a connection topology with a communication network network of Ethernet (registered trademark) or LON (Local 0perating Network (registered trademark)) is free. Possible interfaces are also good.

In this way, the external device 45 connected to the interface device 40 via the connection interface 42 has a threshold value compared with the weighing value information transmitted from the weighing terminal 44 to the interface device 40, and at the time of comparison. Can be set various conditions, the level of forced control according to the comparison result, the control pattern and the like.

The interface device 40 also functions as a web server in which the external device 45 in the host device can set various conditions for executing forced control using the web screen as an interface.

Moreover, when the remote monitoring control system shown in Embodiment 3 shifts to the forced control state by the transmission unit 10 which received the forced control request signal transmitted from the interface device 40, the branch breaker is provided. When it reaches the place, the corresponding branch breaker can be switched off by manual operation.

This is because when the remote monitoring control system transitions to the forced control state, all control requests from the multi-transmission switch terminal 11 are invalidated, thereby preventing unnecessary power consumption and significantly reducing the total usage capacity, thereby stabilizing the entire system. It means you can't respond quickly to demand.

Therefore, even if the remote monitoring control system is in the forced control state, it is not invalidated all the control requests from the multi-transmission switch terminal 11, but is recognized as being effective in the control request for controlling the load in the on state. The function is given to the transmission unit 10. Accordingly, in the remote monitoring control system put into the forced control state by the transmission unit 10, the load consuming unnecessary power in the on state can be turned off in response to a control request from the multiple transfer switch terminal 11. Can be. That is, the cut operation of the unnecessary power of the branch breaker in the on state is not executed directly by manual operation, but can be executed quickly from a remote location.

The function of turning off the load in the on state in the forced control state of the remote monitoring control system by the transfer unit 10 in accordance with the control request of the multiple transfer switch terminal 11 is only the present embodiment. Instead of this, the transmission unit 10 of the remote monitoring control system shown in the first and second embodiments described above may be provided. Moreover, it is applicable also to the transmission unit 10 of the remote monitoring control system shown as Example 4 mentioned later.

(Effect of Example 3)

Thus, in the remote monitoring control system shown as Example 3 of this invention, the metering value information measured by the metering terminal 44 is transmitted to the interface apparatus 40 connected to the signal line Ls, and the interface apparatus 40 is carried out. In accordance with the result of comparison between the threshold value set in advance and the measured value information, the forced control request signal for requesting the transition to the forced control state of the remote monitoring control system is transmitted to the transmission unit 10.

Accordingly, the transmission unit 10 controls the lighting device 13 or the outlet 15 serving as the load according to the control pattern of the forced control request signal, and then invalidates the operation input from the multiple transfer switch terminal 11. Transfer to the forced control state.

Therefore, the interface device 40 is a forced control request signal serving as a trigger for transitioning the remote monitoring control system to the forced control state according to a certain weighing value related to the operating state of the remote monitoring control system weighed by the weighing terminal 44. Since it is possible to send a message to the remote monitoring control system itself or to the central monitoring control system which configures this remote monitoring control system as one local system, it is possible to avoid the problem in advance, so that stable operation can be realized. Can be.

In addition, in the remote monitoring control system shown as Example 4, the same code | symbol is attached | subjected and description is abbreviate | omitted in the location overlapping with the remote monitoring control system shown as 1st-3rd embodiment mentioned above.

As shown in FIG. 5, in the remote monitoring control system shown as Example 4, the transmission unit 10, the several multiple transmission switch terminal 11, and the lighting fixture 13 which is a load are connected, and this load is connected.
