Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the automatic transmission of data from the transmitter side to the receiver by dial-connecting the transmitter to the receiver via a public line network by automatic dial transmission of the transmitter. The present invention relates to an automatic notification system for receiving the data by receiving the automatic dialing in.

[0002]

2. Description of the Related Art As an automatic notification system of this type, for example, a transmitter is provided on the side of a disaster prevention equipment of a building, and a transmitter managing the status of maintenance of the disaster prevention equipment is located at a place remote from the building. The transmitter to send data related to maintenance of the equipment from the transmitter, while the receiver receives the data, and based on the received data, the manager is in a location remote from the building. However, there are some that allow the required response to the disaster prevention equipment in the building.

FIG. 1 is a diagram showing a schematic configuration of the entire automatic notification system.

In FIG. 1, regarding the maintenance status of the disaster prevention facility equipment installed in the building, the sensor inputs from the various monitoring sensors 1a to 1d of the equipment are output to the surveillance board 2, and this surveillance board is also provided. 2 is constantly monitored. Among the monitoring sensors 1a to 1d, 1a is for monitoring the elevator ascending / descending operation which outputs a sensor input by being operated by an elevator person inside the elevator because the elevator 1a is installed in an elevator of a building, and the elevator ascending / descending stops halfway. A sensor 1b is a sensor for monitoring a stored water amount, which is provided in, for example, a water supply facility of a building and outputs a sensor input by detecting the water level of the stored water amount of a water tank in the water supply facility. A sensor for power failure monitoring that outputs a sensor input when it is deployed in equipment and detects a power failure. 1d is a sensor that is deployed in an air conditioning electric motor of a building and detects that the electric motor has failed. It is a sensor for monitoring air conditioning equipment that outputs an input.

[0007] The transmitter 4 takes in the data relating to the maintenance of the equipment from the monitoring panel 2, converts the taken-in data into a form suitable for transmission, and then automatically dials it from the telephone 6 attached thereto. Therefore, the data is transmitted to the receivers 101, 102, ..., 10n at the remote location from the building via the public network 8 when the equipment is abnormal, and when it is normal, it is transmitted at an appropriate cycle.

The receivers 101, 102, ..., 10n have telephones 121, 122 ,.
The data is received by the automatic dial reception of n, and the received data is output to an appropriate output device (not shown). Each output device outputs the data by making a hard copy of the data.

[0007]

By the way, each of the monitoring sensors 1a to 1d is individually set for each of a plurality of monitoring targets, and the monitoring target is in a normal state or in an abnormal state. In addition to detecting whether there is any, a sensor input that turns off (or on) in a normal state and turns on (or off) in an abnormal state is output. And the transmitter 4
To determine whether the monitored target is normal or abnormal, the on (or off) duration when the sensor input changes from off (or on) to on (or off) is determined by the given input filter. Although the input filter time is set to the same fixed length for all the monitoring sensors 1a to 1d, it is performed based on whether or not the time is exceeded.

First, the input filter time depends on the monitoring sensor 1
In addition to the original sensor input from a to 1d, it is set to handle a sensor input that lasts for a certain time as the original sensor input so that so-called noise or the like is not handled by the transmitter 4 as the sensor input. Is something
This prevents the transmitter 4 from making a malfunction report due to noise.

However, if the input filter time is set to a uniform fixed length for any sensor input regardless of the nature of the monitored object, when the monitored object is, for example, a water supply facility, the water level of the water storage tank is set. Even if the time during which the water level does not correspond to the original amount of water stored due to unnecessary fluctuations of the input filter time is only temporarily exceeded, the transmitter 4 has insufficient water storage capacity in the water storage tank. It judges that there is and reports malfunction. Therefore, in such a case, it is preferable to set a long input filter time so that a malfunction is not notified due to a temporary fluctuation in water level.

Although it is considered that the rotation speed of the air conditioner electric motor fluctuates greatly depending on the time of use and the time of use of the air conditioning equipment, if the input filter time is constant, the electric motor will rotate normally. However, it is misjudged that it is rotating abnormally and is reported.

Therefore, in the present invention, the filter time of the sensor input is made variable according to the monitoring target,
The purpose is to prevent false notifications about the condition of the monitored object.

[0012]

In order to achieve such an object, the automatic notification system of the present invention has a monitoring sensor, a transmitter, and a receiver, and the monitoring sensor is a monitoring target. The transmitter detects a state and outputs a sensor input corresponding to the detection. The transmitter determines the state of the monitoring target based on the sensor input, and transmits monitoring data corresponding to the determination to the public line network. Via automatic dial transmission to the receiver, the receiver receives the monitoring data from the transmitter by automatic dial reception, and the transmitter also inputs the duration of the sensor input. Based on whether or not the filter time is exceeded, it is determined that the status of the monitored object has changed, and the input filter time is variable. It is set to.

[0013]

In the transmitter, since the input filter time is variable, the input filter time for filtering the sensor input from the monitoring sensor is set according to the monitored object. Then, the transmitter receives a sensor input corresponding to the state of the monitoring target from the monitoring sensor. The transmitter determines the state of the monitoring target based on this sensor input, and sends the monitoring data corresponding to the determination to the receiver via the public line network by automatic dial transmission. Receive monitoring data from the machine by automatic dial reception. Here, the transmitter makes the above determination based on whether the duration of the sensor input exceeds the input filter time.

[0014]

Embodiments of the present invention will now be described in detail with reference to the drawings. The automatic notification system of the present invention will be described by applying it to an automatic notification system relating to the state of building equipment and the like, but since the basic configuration is the same as in FIG. 1, the details of the basic configuration will be replaced with the above. The configurations of the transmitter and the receiver of FIG. 1 are shown in FIGS.
The configuration of the system of the present invention will be described with reference to FIG.

In the transmitter 4 shown in FIG. 2, 14 is an input circuit, 16 is an output circuit, 18 is a CPU, 20 is a signal generator, 22 is a signal receiver, 24 is a line interface, 26 is an interface, and 28 is It is a memory.

The sensor input provided from each of the monitoring sensors 1a to 1d for monitoring the condition of the equipment / devices installed in the building through the monitoring panel 2 of FIG.
Digitally encoded by the input circuit 14 from the input circuit 14
It is given to the PU 18. Here, the sensor input from the monitoring sensor 1a is the monitoring of the elevator's ascending / descending operation, the sensor input from the monitoring sensor 1b is the monitoring of the amount of water stored in the water tank of the water supply facility, and the sensor input from the monitoring sensor 1c is the power failure of the electrical facility. And the sensor input from the monitoring sensor 1d are related to the rotation speed monitoring of the electric motor of the air conditioning equipment. If they are normal, the sensor input is off, and if they are abnormal, the sensor input is on. Is.

The CPU 18 determines from the encoded sensor input whether or not an abnormality has occurred in the equipment, and controls the transmission of data to each of the receivers 101 to 10n.

The CPU 18 also receives the receivers 101 to 10n.
The telephone numbers of the telephones 121 to 12n attached to the memory 28
Then, the provided maintenance data is read from the signal generator 20 together with the read telephone number.
Output to. The signal generator 20 converts the transmission data from the CPU 18 into a form that can be put on the public line network 8, and then receives the signals from the receivers 101 to 10 through the public line network 8 from the line interface 24.
Send to the n side.

The transmitted data includes not only the above data in the memory 28 but also the name of the site where the equipment is installed and other necessary data, which are written in by the writer (programmable console) 29. Given to the CPU 18 via the interface 26 from the CP
U18 stores them in memory 28 in response to its write input.
You can remember it.

Here, the writer 29 is of a handy type and is connected to the transmitter 4 by a connector or the like, and the sensor input from each of the monitoring sensors 1a to 1d is filtered by a keyboard mounted therein according to the monitoring target. The input filter time to be input can be input to the CPU 18 via the interface 26, and the input filter time can be stored in the memory 28.

For example, a monitoring sensor 1a for monitoring the elevator ascending / descending operation and a monitoring sensor 1c for monitoring a power failure of electric equipment.
The writing time is set so that the filter time of the sensor input from each is short and the filter time of the sensor input from each of the monitoring sensor 1b for monitoring the water supply facility and the monitoring sensor 1d for monitoring the electric motor of the air conditioning facility is long. To do.

Therefore, for example, the water storage monitoring sensor 1
Even if the sensor input of b changes from the off state where the corresponding device is normal (the water storage amount is at the specified value) to the abnormal state (the water storage amount is insufficient), the on state When the input filter time exceeds the input filter time, the transmitter 4 can determine that the water storage amount corresponding to the monitoring sensor 1a is insufficient, and the input filter time corresponds to each monitoring target. Since it is set, it is possible to make a judgment suitable for each monitoring target.

The receivers 101 to 10n shown in FIG.
It has a line interface 30, a signal generator 32, a signal receiver 34, a CPU 36, a memory 38, and an input circuit 40.

Line interface 30, signal generator 3
2, the signal receiver 34, and the memory 38 have the same functions as those in FIG. 2, and thus detailed description thereof will be omitted. The input circuit 40 is for inputting command data to the transmitter side by a push button operation or the like from the receiver side. The CPU 36 receives the command data from the input circuit 40, the transmitter 4 side through the public line network 8 and the line interface 30, and the signal receiver 3
In step 4, the data that has been appropriately processed and input in 4 is captured and processed.

The operation centered on the CPU 36 of the transmitter 4 will be described with reference to the flowchart shown in FIG.
At step n1, the writer 2 is stored in the memory 28 of the transmitter 4.
The input filter time set in 9 is set and stored. That is, in the past, the input filter time was fixed to a fixed time irrelevant to the monitoring target, but in the present embodiment, it is individually set variable according to the nature of the monitoring target.

Then, from each of the monitoring sensors 1a to 1d, a sensor input is output to the transmitter 4 in a time division manner via the monitoring board 2. Then, the transmitter 4 determines in step n2 whether or not there is a sensor input that has changed from off to on from the monitoring sensors 1a to 1d, and if there is a sensor input whose detection state has changed to on, the transmitter 4 notifies the CPU 36 in step n3. Starts the operation of the built-in timer. When the timer operation starts, it is determined in step n4 which monitoring sensor the sensor input is from. After this determination, the CPU 36 reads the input filter time corresponding to the monitoring sensor from the memory 28, and in step n5 determines whether the ON duration exceeds the input filter time. If it does not exceed, even if the sensor input is turned on, the timer is reset in step n7 and the process returns to step n2. If it exceeds, in step n6, the receiver side is notified that the equipment corresponding to the sensor input is abnormal. To do.

[0027]

As is apparent from the above description, according to the present invention, the monitoring sensor detects the state of the object to be monitored and outputs the sensor input corresponding to the detection, and the transmitter inputs the sensor input. The status of the monitoring target is judged based on the judgment, and the monitoring data corresponding to the judgment is transmitted to the receiver through the public line network by automatic dial transmission, and the receiver receives the monitoring data from the transmitter by automatic dial reception. In addition to receiving the signal, the transmitter determines that the state of the monitoring target has changed based on whether or not the duration of the sensor input exceeds the input filter time, and the input filter time is made variable. It is possible to make a notification regarding the status of the monitoring target according to the nature of the target, and therefore it is possible to make an error report to the receiver. It is eliminated.
