Abstract

PURPOSE:To save a trouble setting a delay time for each terminal equipment interface by operating or stopping each terminal equipment with automatic formation of dispersed delay time different from each terminal equipment interface automatically through the detection of a power supply interruption sensing section so as to avoid simultaneous operation/stop. CONSTITUTION:A delay time control section 17 is connected between a communication control section 15 and a device control section 13 and a power interruption sensing section 14 and a random number generating section 18 are connected and when an operation/stop command signal from a terminal equipment 12 sent from a remote controller 11 is inputted to the communication control section 15, the output is delayed by a random delay time generated by the random number generating section 18. Moreover, when a sensing signal of power failure supplied to the terminal equipment 12 is inputted from the power failure sensing section 14, the delay time generated by the random number generating section 18 is corrected newly by a delay time control section 17. Thus, even if the form of the system is revised, dispersed delay time is automatically set so as to avoid simultaneous operation/stop.

Description

[Detailed Description of the Invention] Industrial Field of Application What is the scope of the present invention? 1! Jl connected by a bus-style signal line to a remote control device for remotely starting/stopping multiple terminal devices.
, , relates to a terminal equipment interface that controls operation/stop of the terminal equipment and monitors the status of the terminal equipment.

2. Description of the Related Art Conventionally, a remote control system has a configuration as shown in FIG. The remote control device 1 and each terminal device interface 2 are connected by a bus-type signal s3. Also,
Each terminal device 4 operates/stops by outputting a start/stop control signal from the corresponding terminal device interface 2.

The state is output as a state monitor signal.

Next, the block configuration of the terminal device interface 2 will be explained using FIG. 3.

In FIG. 3, a communication control section 5 receives a start/stop instruction packet sent from a remote control device 1 to a terminal device 4 via a signal line 3, and transmits it to a delay control section 6. Converts the status monitor signal of the terminal device 4 inputted from the terminal device 4 via the device control unit 7 into a transmission packet and sends the signal #
13 Send up. The delay time setting section 8 is connected to the delay time control section 6, and is used to set the delay time from dusk to the actual start/stop operation of the start/stop instruction signal to the terminal device 4 to a certain fixed time. Yes, the delay time control unit 6 controls the operation/delay from the communication control unit 5 to the terminal device 4.
After receiving the stop instruction signal, the signal is delayed by the delay time determined by the delay setting section 8, and the contents thereof are transmitted to the device control section 7. In a system in which a large number of terminal devices 4 are connected, the delay time control section 6 and delay time setting section 8 are configured to control each terminal device 4 when the remote control device 1 issues an instruction to start/stop all the terminal devices 4 at once. This is provided to avoid insufficient power supply capacity due to the simultaneous operation and stopping of the power supply and the flow of a large current. When the device control section 7 receives the operation/stop instruction signal for the terminal device 4 from the delay time control section 6, it immediately outputs a control signal to cause the terminal device 4 to operate/stop. In addition, the device control section 7
The operating/stopping state is manually monitored from the terminal device 4, and if the state changes, it is transmitted as a state monitor signal of the terminal device 4 onto the signal line 3 via the communication control unit 5.

Problems to be Solved by the Invention However, in the conventional configuration as described above, when a large number of terminal devices 4 through which a large current flows at the start of operation/stop are connected to the same system, all the delay times of each terminal device interface 2 are In order to ensure that the delay times are different, the user must initialize the delay time in advance using the delay time setting section 8.
The problem is that it is difficult to evaluate whether the delay time initially set for each system is appropriate for the system.

In addition, the type of terminal equipment (load transient characteristics) and number of connections,
Depending on the power supply capacity supplied to each terminal device, the start/stop start time interval that should be staggered when starting/stopping multiple terminal devices, that is, the delay time for each terminal device interface 2, can be changed. Therefore, each time the system configuration is changed, the user has to change the delay time setting of each terminal device interface 2 one by one through trial and error.

The present invention solves the above-mentioned conventional problems, and when connecting a large number of terminal devices that draw large currents to the same system or when changing to a new system, there is no need to initialize the delay time in advance, and the delay time is automatically set. It is an object of the present invention to provide a terminal device interface that can set a delay time suitable for the system and prevent the system from going down due to insufficient power supply capacity.

Means for Solving the Problems In order to solve the above problems, the terminal device interface of the present invention is connected to a remote control device by a signal line, and receives a start/stop instruction signal for the terminal device sent from the remote control device. , a communication control unit that transmits a status monitor signal from the terminal device; and a communication control unit that outputs a control signal for operating/stopping the terminal device in response to a run/stop instruction signal from the communication control unit, A 4Ik device control section that outputs a status monitor signal to a communication control section, and a starting current when the terminal device is started/stopped by the control output from the device control section, and the power supplied to the terminal device is controlled. a power-off detection unit for detecting whether or not a power-off detection unit has fallen; a random number generation unit for generating a random delay time; and a power-off detection unit and a random number generation unit connected between the communication control unit and the device control unit. When the terminal device is connected and a start/stop instruction signal for the terminal device sent from the remote control device is input from the communication control unit, the terminal device is activated after a random delay time generated by the random number generator. A signal to start/stop is transmitted to the device control section, and when a detection signal indicating that the power supply to the terminal device has been cut off is input from the power cutoff detection section, the random number generation section generates a and a delay time control section that newly corrects the delay time.

Effect With the above configuration, when a terminal device operation/stop instruction signal sent from a remote control device is input from the communication control section,
A signal to start/stop the terminal equipment after a random delay time generated by the random number generator is transmitted to the equipment control unit, and a detection signal indicating that the power supply to the terminal equipment has been cut is transmitted to the power-off detection unit. When input from , the delay time generated by the random number generator is newly corrected by the delay time control unit, so even when a large number of terminal devices that draw large currents are connected to the same system, the system may go down due to insufficient aS capacity. In the unlikely event that the power supply to the terminal device is cut off even though the terminal device is started/stopped after a random delay time generated by the random number generator, It learns to newly correct the random delay time that was generated, and automatically finds a delay time that, at worst, will not cause the terminal device to turn off, depending on the system configuration.

Therefore, even if the system configuration is changed, each terminal device interface must automatically wait for a delay time that varies individually before starting/stopping each terminal device so that they do not start/stopping at the same time. become,
This saves the user the trouble of setting the delay time for each terminal device interface.

Example An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a terminal equipment interface according to an embodiment of the present invention. In FIG. 1, when starting/stopping the terminal device 12 based on an instruction from the remote control device 11, the device control unit 13 outputs a pulse waveform to the terminal device 12 to start/stop the terminal device 12. The toggle is alternately reversed, and at the same time, the power-off detection unit 14
Monitoring of the power supply status to the terminal equipment 12 is started. Conversely, the status from the terminal equipment 12 is taken into the equipment control unit 13 by level input, and changes from the operating state to the stopped state,
Alternatively, when the stopped state changes to the operating state, the changed state monitor signal is transmitted to the communication control unit 15.

The communication control unit 15 exchanges packets with the remote control device 11 according to a predetermined procedure.
demodulates the operation/stop instruction packet for the terminal device 12 sent from the terminal device 12 via the signal line 16, and transmits this as received data to the delay time control section 17, and also for the terminal device sent from the device control section 13. 12 status monitor signals are converted and modulated into transmission packets.

It is sent to the signal line 16. The random number generator 18 is connected to the delay time controller 17 and generates a random delay time within a certain range, which is actually a remote control bag! This is adopted as the initial reference time for the time to be delayed from when an instruction to start/stop the terminal device 12 is received from the terminal device 11 until it starts operating. The power failure detection unit 14 detects that when a plurality of terminal devices 12 are operated according to a start/stop instruction for the terminal devices 12 from the remote control device ll, the power light of the AC 100V line supplied to the terminal devices 12 is caused by a starting current. This monitors whether the power has been turned off or not, and in the event that the power is turned off, the delay time control unit 17
The delay time held as the initial reference time is newly corrected. That is, the delay time control section 17 further delays the start/stop instruction signal sent from the remote control device 11 via the signal line 16 and the communication control section 15 to the terminal device 12 before transmitting it to the device control section 13. The method of calculating the delay time is based on a random value within a certain range generated by the random number generator 18, but in the event of a power outage, a small amount of delay time is added each time. The configuration is such that the value is corrected.

With the above configuration, the terminal device 1 from the remote control device 11
When the start/stop signal of 2 is received, the terminal device 1 actually
A delay time until the start/stop operation of 2 is automatically given depending on the system configuration, thereby preventing the system from going down due to insufficient power supply capacity.

Effects of the Invention As described above, according to the terminal device interface of the present invention, when a plurality of terminal devices through which a large current flows at the start of operation/stop are connected, - start/stop instructions can be issued to multiple terminal devices at the same time. As a countermeasure against power supply capacity shortage when the Since the terminal device is started/stopped, the user does not have to take the trouble of setting the delay time for each terminal device interface.

Furthermore, even if the system configuration changes, such as the type of terminal equipment (load transient characteristics), the number of connections, or the power supply capacity supplied to each terminal equipment, the delay time suitable for the new system configuration will be automatically updated by learning. This greatly improves the scalability and flexibility of the entire system.
