Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an emergency notification device that makes an emergency notification to a specific destination when an abnormality occurs.

[Background Art] Conventionally, as shown in FIG. 2, this type of emergency notification device A includes a plurality of abnormality monitoring sensors 1 and one
and a reporting means 2 that sends an emergency notification to a specific notification destination B when an output is obtained, and sends data indicating the type of number of the sensor 1 from which the output was obtained by detecting an abnormality to the emergency notification. Data was transmitted via telephone lines or wireless communication equipment. however,
In such a conventional example, the actual operating state fi (for example, changes over time) of sensor 1 is unknown, so if a malfunction occurs, it is necessary to go to the site and check the operating state of sensor 1. However, there is a problem in that it is troublesome to deal with malfunctions.

E. Purpose of the Invention The present invention has been made in view of the above-mentioned problems, and its purpose is to be able to accurately grasp the actual operation of the sensor, to determine whether or not it is a false alarm, and to detect the occurrence of a malfunction. An object of the present invention is to provide an emergency notification device that can easily deal with problems.

[Disclosure of the Invention] (Embodiment) Fig. 1 shows an embodiment of the present invention, which includes a sensor 1 for monitoring an abnormality, and a system that sends an emergency report to a specific notification destination B when the output of the sensor 1 is obtained. In an emergency notification VC device A similar to the conventional example, which is equipped with a notification means 2 that performs A data memory 4 for storing data is provided, and the sampling data stored in the data memory 4 is transmitted together with the emergency report data at the time of emergency report. Here, the sampling means 3 is formed of a microcomputer using a CPU, and is configured to create emergency report data based on sampling data and to arbitrarily set sampling intervals. In addition, the data memory 4 includes each sensor 1.
It is formed by a 2-bit shift register 5 provided correspondingly to the sensor 1, and can store only 2 bits of sampling data of the output of each sensor 1. In addition, in the embodiment, the reporting person y, 2 is connected to the telephone line 6.
However, it goes without saying that a non-glandular communication device using radio waves or light may also be used. Further, the shift register 5 for storing sampling data may be formed by a RAM controlled by the microcomputer of the sampling means 3.

The operation of the embodiment will be described below. Currently, the sampling means 3 samples the sensor 1 output at fixed time intervals and writes it into the corresponding shift register 5, and the shift register 5 always stores sampling data within a predetermined time Zkt. ing.

The sampling means 3 outputs the emergency report data, assuming that an abnormality has been detected by the sensor 1 only when the same data is obtained several times (for example, twice) after the sampling data changes. This is to prevent malfunctions. Here, some abnormality occurs and the sensor 1 output changes, and after this change is read by the sampling means 3, normal operation continues during kt (while checking for malfunction). There is. After that, that is, after the abnormality detection is deemed not to be a malfunction, the sampling means 3 sequentially reads out the sampling data from the shift register 5 to 2 and stores it in the internal memory (R'AM).

The sampling data stored in the shift register 5 is output from the sampling means 3 together with emergency report data such as data indicating the number and type of the sensor 1.
It is transmitted to the reporting destination B via the reporting means 2 and the telephone line 6. On the other hand, at destination B, emergency call equipment r! By displaying these data sent from LA, the administrator can determine whether the emergency call is a false alarm or not, or by using a computer to compare it with data from previous malfunctions to determine whether it is a false alarm or not. It has become. In addition, in the event that a false alarm is determined, by analyzing the actual operating state of sensor 1 using the sampling data transmitted with the emergency call, the situation of the malfunction can be grasped without going to the scene.
This makes it easier to deal with malfunctions.

In the embodiment, shift registers 5 are provided for all sensors 1, but it is also possible to provide shift registers 5 only for sensors 1 that are likely to malfunction and send sampling data. Good. Also, if you prepare several shift registers 5 to store sampling data, and store the sampling data of sensor 1 that is likely to malfunction specified by destination B in these shift registers 5, you can increase versatility. This will increase the size and waste the circuit.Furthermore, by sequentially discontinuing ?ffH2 of the sampling data of sensor 1 for which countermeasures against malfunctions have been completed, the shift register 5 will eventually become unnecessary. The shift register 5 can be removed. Therefore, if the shift register 5 is made detachable and the M product of the sampling data is performed only when checking for malfunction, the circuit can be rationalized.

By the way, in the embodiment, when the operation of the sensor 1 is confirmed by the sampling means 3, immediately after that, for a certain period of time (
KL) of sampling data is transmitted to the destination together with the emergency report data, but with this, it may not be possible to determine whether the noise is temporary or steady. In such a case, the operation of sensor 1 should be monitored by transmitting a transmission request signal for the sampling data of a specific sensor 1 from the notification destination B after an appropriate period of time, and monitoring the returned sampling data. If you monitor the actual operation of sensor 1 in this way, you can detect a short operation (
By reliably understanding cases such as when the operation below kt occurs frequently, the operation of the sensor 1 can be analyzed in more detail.

[Effects of the Invention 1] As described above, the present invention provides an emergency notification installation equipped with a sensor for abnormality monitoring and a notification means for sending an emergency notification to a specific notification destination when the sensor output is obtained. A sampling means for sampling the output at fixed time intervals is provided, and a data memory is provided for storing a predetermined number of sampling data sampled by the sampling means, and when an emergency call is made, the sampling data stored in the data memory is used as emergency call data. Since the information is transmitted together with the alarm, the actual operation of the sensor that is the basis for the emergency report can be accurately grasped, and there is an effect that it is easy to determine whether or not it is a false alarm and to deal with the malfunction.
