Description

TECHNICAL FIELD The present invention relates to an automatic reporting system for home security information such as crime prevention and disaster prevention.

2. Description of the Related Art Generally, as shown in FIG. 2, an automatic notification system has a configuration in which predetermined information is transmitted from a plurality of slave stations 20, 23, 24, 25 to one master station 19, and many slave stations are provided. The main case is to use a telephone line, such as when a station has information or obtains information about a child station at a remote place. The master station 19 of this conventional example includes a first communication control unit 3 that receives a signal from each slave station, and a signal processing unit 5 that processes information from the slave station. Also, a child station
Reference numeral 20-6 is a second communication control unit, which transmits a signal from the monitoring unit 9 for monitoring an abnormal state of the sensor or the terminal 13 to the master station via the notification unit 11. 22 is a counting unit having a clock function,
At a predetermined time set by the 21 notification time setting unit, a count is performed to periodically notify the master station of the detection state of the monitoring unit. The time interval of the periodical notification may be various units such as hourly unit, daily unit, and monthly unit, and is adjusted by the notification time setting unit of 21. Also,
In the above, only the periodical notification is mentioned, but the system also has an automatic notification function for immediately reporting to the master station when an abnormality occurs in the sensor or the terminal device.

The problem to be solved by the invention However, in such an automatic notification system, if the time zone reported from each slave station overlaps, the line becomes very crowded and an emergency signal is promptly transmitted when an abnormality occurs. Some things were not done. Therefore, it is set at the time of installing each slave station so that the time of regular notification to the master station does not overlap among slave stations, but it is necessary to specify a predetermined area or each housing complex, and , There was something very inconvenient in terms of construction and management, such as what time zone should be allocated during installation work. Also, a system was set up in which the time from the master station to each of the slave stations was set directly by using the line, but the number of slave stations was increased to thousands or tens of thousands. In that case, there are many inconveniences such as occupying a line from the master station for a long time and having to manage time allocation for all slave stations.

The present invention solves such a conventional problem, and it is possible to control the time of regular notification to the master station with a simple configuration, and moreover, the line to the master station serving as the center is always crowded. It is intended to provide an excellent automatic notification system that does not exist.

Means for Solving Problems The automatic notification system of the present invention has a relay station that functions as a sub-center between a master station and each slave station, and sets a regular notification time within the master station. It is composed of a setting signal output unit, a second time setting signal output unit in each relay station that monitors a predetermined slave station group, a monitoring unit of each slave station, a notification unit, and a counting unit.

Action In the automatic reporting system of the present invention, the master station specifies the regular reporting time for each relay station, and each relay station outputs the second time setting signal to each slave station of the slave station group that it monitors. The department assigns the time for regular notification. In each slave station, a detection signal of a sensor or a monitoring unit that monitors the state of the terminal device is transmitted to the master station via the relay station at the set regular notification time. Then, the time management in each slave station is performed by the counting section having a clock function, and when the predetermined time comes, the reporting section is operated to execute the regular reporting to the master station as described above. Therefore, the main station, which is the center,
Manages the time of regular notifications to all slave stations.
It is not necessary to specify, and the relay station with a small number of parameters to monitor is assigned the time of each slave station, so that the line is efficiently used.

Example An automatic notification system according to an example of the present invention will be described below with reference to FIG.

As shown in the figure, one master station outputs a first communication control unit 3 that performs signal transmission with each relay, and a first time setting signal output that sets a regular notification time for each relay station. It comprises a unit 4 and a signal processing unit 5 for processing the signal information of each slave station sent through each relay unit. The relay station 2 also monitors the master station and each slave station of the slave station group to be monitored according to the second communication control unit 6 and the regular notification time transmitted from the master station. It comprises a second time setting signal output section for setting the respective regular notification times for each slave station to be set. Then, each slave station 8 monitors the state of the terminal device 13 such as a crime prevention or disaster prevention sensor or a gas appliance by the monitoring unit 9, and performs a transmission control with the relay station. The regular notification time is transmitted from the communication control unit 10 to the counting unit 12 and the counting unit 12 having a clock function performs the counting and also notifies the notification unit 11 to transmit the detection state of the monitoring unit at the predetermined time. to start. Reference numeral 14 is another slave station monitored by the relay station 2 and has the same function as the slave station 8. 15
Is a sensor or a terminal device whose status is monitored by the slave station 14. Reference numeral 16 denotes another relay station, which, like the relay station 2, has a communication control unit and a time setting signal output unit, and monitors the slave station 17 and the like. Reference numeral 18 denotes a sensor or a terminal device whose state is detected by the slave station 17. Although not shown in the figure,
A plurality of slave stations perform signal transmission to each relay station, and are monitored by each relay station as a slave station group.

The first time setting signal output unit 4 in the master station 1 transmits to each relay station the time at which the master station should be notified periodically, and the second time setting signal output unit of each relay station monitors. The time at which the information of the monitoring unit is transmitted is assigned to each slave station of the slave station group. That is, the master station specifies the regular notification time to the relay station at a predetermined time interval, and the relay station sets each regular notification time to each slave station according to the specified time. By doing this, the parent station does not need to manage the regular report time for all child stations,
In addition, the line can be effectively used at the time of setting. Further, as a matter of course, when the monitoring unit in each slave station detects an abnormality in the sensor, the terminal or the like, it immediately and automatically notifies.

EFFECTS OF THE INVENTION As described above, the automatic notification system of the present invention provides a sub-center-like relay station that monitors a predetermined group of slave stations between the master station that is the center and each slave station, and the regular station within the master station The relay station is provided with a second time setting signal output section for receiving the signal of the first time setting signal output section for setting the notification time and allocating the regular notification time of each slave station to the relay station. Manages the time for regular notifications for multiple slave stations,
There is no need to set it, the burden is reduced, and effective use of the line is achieved. In other words, when installing an automatic notification system, it is not necessary to manage each regular notification time at the time of setting the slave station, and the setting can be changed on the master station side via the relay station, so it increases as the number of slave stations increases as a system. The more convenient and effective it becomes.
