Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a remote control monitoring system used for controlling intercoms and electric locks, and monitoring disaster prevention and crime prevention in large-scale housing complexes such as Manshirin.

[Background Technology J] This type of remote control monitoring system, which has traditionally been used to control intercoms and electric locks in large-scale housing complexes such as condominiums, and to monitor disaster prevention and crime prevention, is shown in Figure 3. A central control monitoring device 1 disposed in Address data for calling 2 and control data for controlling loads such as intercoms and electric locks are time-division multiplex transmitted via signal #i3 to remotely centrally control the loads, and from each terminal 2 to central control and monitoring device 1i: self. In addition to time-division multiplexing transmission of monitoring data such as the unique address data of the sensor 9 and the output of sensors 9 such as fire sensors and crime prevention sensors via the signal @3, the monitoring status display unit provided in the central control monitoring device 1 is displayed on the terminal device 2. Based on the unique address data and monitoring data transmitted from the system, the monitoring status was displayed and remote centralized monitoring was performed. In addition, intercom devices 10a are installed in the manager's room, entrance lobby, and each residence.
, 10b, and 10c are controlled by the remote control monitoring system according to the present invention, and the communication lines are separately wired. In addition, the signal line 3 uses a power line that supplies AC power to the terminal device 2, and in this case, the transmission signal is transmitted using the so-called power line carrier method in which a high frequency signal is superimposed on the AC power. There is.

By the way, in such a conventional example, if you want to check the monitoring status at a location away from the central control monitoring device 1,
The sub-monitoring device 4 was provided with a light-emitting diode that took out the monitoring status display data of the central control monitoring device 1 as a contact signal to the outside and blinked in response to the contact signal. However, in such a conventional example, there is a problem that when the amount of monitoring information increases, the number of wires 5 for inputting the contact signals to the sub-monitoring device 4 increases, making the wiring work troublesome. Furthermore, since it is difficult to take noise countermeasures to each wiring 5, the wiring 5 cannot be made too long in consideration of noise resistance, and the sub-monitoring device 4 can be arbitrarily separated from the central control monitoring device 1. There was a problem that it was not possible to place the

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to simplify the wiring and also to enable the sub-monitoring device to be arbitrarily separated from the central control monitoring device. The object of the present invention is to provide a remote control and monitoring system that can be deployed at any location.

[Disclosure of the Invention] (Embodiment) FIGS. 1 and 2 show an embodiment of the present invention. In a remote control monitoring system similar to the conventional example, the signal line 3 is connected to The signal monitoring means 6 receives the transmission signal from the terminal 2 transmitted via the signal monitor 3, and displays the monitoring status based on the unique address data and monitoring data of the terminal 2 received by the signal monitor Fi6. A sub-monitoring device 8 equipped with a monitoring status display means 7 is provided. In the embodiment, the signal monitoring means 6 includes a multiplex transmission modulation/demodulation circuit 11 that receives and demodulates a high frequency signal superimposed on an AC power source and transmitted, and a logic circuit that reproduces data from the demodulated transmission signal. 12, an I10 circuit 13 that outputs the reproduced data, and a constant voltage circuit 15 that forms a circuit power supply by rectifying the AC power input through the block filter 14 and making it a constant voltage. Yes, a surveillance letter! ! ! ! The display means 7 includes an I10 circuit 16 that receives data output from the signal monitor means 6;
A logic circuit 17 that creates display data and alarm data based on the captured data; Control circuit 18 to control
It is made up of.

According to the present invention, the sub-monitoring device 8 is provided with the signal monitoring means 6, and when installing the sub-monitoring device 8, the pair of signal lines 3 are simply extended and connected to the sub-monitoring device 8. This simplifies wiring work and reduces costs. Furthermore, since data is transmitted to the sub-monitoring device 8 using a signal transmission system that generally has sufficient noise resistance, there is no problem even if the length of the extended signal line 3 is increased ( The sub-monitoring device 8 can be placed arbitrarily away from the central control monitoring device 1.Furthermore, the sub-monitoring device 8 simply monitors the signal on the signal line 3; Since it is never accessed, there is no need to set a unique address to the sub-monitoring device 8 (by providing the sub-monitoring device 8, there is no need to change the control monitoring program of the central control monitoring device 1. ing.

If the sub-monitoring device 8 according to the present invention is integrated into the intercom 10b for the entrance lobby, a composite intercom with a monitoring function can be formed. Furthermore, it goes without saying that the sub-monitoring device 8 according to the present invention can be used as a line monitor during maintenance.

Furthermore, in addition to the monitoring status display means 7, a printer output means may be provided to print out the monitoring status, or an image processing microcomputer may be provided to display the monitoring status as simple figures, pictograms, etc. on the CRT. It is also a good idea to install an emergency call device that makes emergency calls via a telephone line.
It may also be possible to notify the outside of an emergency situation in the monitoring state.

[Effects of the Invention 1] As described above, the present invention connects a central control monitoring device and a plurality of terminal devices each having a unique address by a signal line,
Address data for calling terminal devices and control data for controlling loads are time-division multiplexed transmitted via signal lines from the central control monitoring device to perform remote central control of the load, and each terminal device transmits its own unique address to the central control monitoring device. In addition to time-division multiplexing transmission of data and monitoring data such as fire sensor and security sensor output via signal lines, unique address data and monitoring data transmitted from the terminal to the monitoring status fi display section provided in the central control monitoring device. In a remote control monitoring system configured to perform remote centralized monitoring by displaying a monitoring status based on a signal line, a signal monitor means for receiving a transmission signal from a terminal device connected to a signal line and transmitted via the signal line; A sub-monitoring device is provided with a monitoring status display means for displaying the monitoring status based on the unique address data of the terminal device and the monitoring data received by the signal monitoring means, and a pair of signal lines are extended. Since the sub-monitoring device can be installed by simply connecting the sub-monitoring device to the sub-monitoring device, the wiring work for the sub-monitoring device can be simplified. Since data is transmitted to the sub-monitoring device using the system,! There is no problem even if the length of the L-length signal line is increased, and the advantage is that the sub-monitoring device can be arbitrarily placed away from the central control monitoring device.
