Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an address setting method for setting an address number to a terminal in various monitoring systems such as crime prevention and disaster prevention, and a terminal and a monitoring device used in this method.

[0002]

2. Description of the Related Art In various surveillance systems for crime prevention, disaster prevention, etc., a system for centrally monitoring by giving a unique address number to each terminal so that the operating state of each terminal placed in the monitoring area can be grasped It has been known. Conventionally,
In order to set an address number on such a terminal,
For example, an address number is set by operating a dip switch or a thumb rotary switch in the terminal device before attaching the terminal device to the monitoring area.

[0003]

However, since the conventional address setting method is a method of operating the switch to set the address number, the address number is erroneously set, or the address number is set in advance. Even if it was set correctly, there was a possibility that it would be installed at a different address number when installing the terminal. Therefore, it is necessary to confirm the address number after installing the terminal device, and moreover, multiple workers must make a pair on the terminal device side and the monitoring device side to confirm it. Met. Further, since the switch for address setting is generally provided at a position where it can be operated from the outside, the terminal device cannot be made to have a sealed structure, and there is a risk that it may be mischievous or rain or the like may enter. Therefore, an object of the present invention is to solve the above problems, an address setting method capable of easily performing an address setting operation, and improving the sealing property of a device, and a terminal device used in this method and the same. To provide a monitoring device.

[0004]

According to the present invention, instead of operating a switch to set an address number, communication is performed between a monitoring device and a terminal device connected via a communication path, and the monitoring is performed. The above problem is solved by configuring the address number determined by the device to be set in the terminal device. The basic technical idea of the address setting method according to the present invention is that, in a communication method in which a plurality of terminals are connected to a monitoring device via a communication path, each terminal side has an excitation means that is excited by a specific operation. And transmitting means for transmitting an address request signal to the monitoring device by excitation of the excitation means, and storage means for storing the address number transmitted from the monitoring device, and transmitting from the terminal device to the monitoring device side. When the excitation means provided on the terminal side is excited by providing means for determining the address number of this terminal in response to the address request signal and means for transmitting this address number to the terminal An address request signal is transmitted from this terminal device to the monitoring device, and an address number of this terminal device is transmitted from the loopback monitoring device and stored in the storage means. It is to the address setting method. Preferably, it is preferable that the excitation means includes a magnetically excited reed switch.

[0005]

According to the above-mentioned embodiment, by excitating the exciting means of the terminal, the address setting is transmitted / received to / from the monitoring device, and the address number is sent from the monitoring device to the terminal. With this, the address number is sequentially determined by performing a predetermined operation, preferably by exciting the reed switch with a magnet after mounting the terminal device, so that the work of operating the switch to set the address number is eliminated, Problems such as an address setting error and a terminal device mounting error in the above are solved.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which this address setting method is adopted in a crime prevention system. In the figure, 1 is a security sensor arranged in a warning area, which corresponds to a terminal device in the present address setting method, and 2 is a security monitoring device for centrally monitoring a plurality of security sensors 1. Corresponds to the monitoring device in. Security monitoring device 2
A plurality of security sensors 1 are connected in series with a small number of electric wires 3.

The security sensor 1 is connected to, for example, an intrusion sensor main body 10 having a pyroelectric element, the sensor main body 10 and the like, and outputs a signal obtained by adding an address number to a detection signal from the sensor 10 when the sensor 10 is operated, for example. A CPU 11 for generating and controlling communication with the monitoring device 2, a communication device 12 for communicating with the monitoring device 2, a magnet reed switch 13 that is connected to the CPU 11 and excited when an address is set, and a set address. E to store the number
It is configured to include an EPROM 14 and an LED 15 which is connected to the CPU 11 and indicates the operation and address number of the sensor body.

The monitoring device 2 includes a CPU 21 for controlling the security system, a storage device 22 for storing the control program and data, an operation unit 23 for selecting the control mode, an indicator light, an LED or A display unit 24 for displaying operation contents and alarm contents by a liquid crystal or the like, and CPU 21
The communication device 25 is controlled by the communication device 25 and transmits / receives to / from the crime prevention sensor 1, and the communication device 26 for connecting to a higher monitoring system to construct a hierarchical structure type monitoring system.

Next, the operation of setting the address number of each security sensor with the above configuration will be described. The security sensor 1 has been installed in each security area according to the security plan, and is connected to the monitoring device 2 by the communication device 12.
At this point in time, each security sensor does not have an address number, and only the power is supplied from the monitoring device 2.
When an operator operates a mode setting switch (not shown) on the operation unit 23 of the monitoring device 2 to set the address number, and the monitoring device 2 enters the address setting mode, the monitoring device 2 prepares for a call from the security sensor. Will be in a standby state.

On the security sensor side, the address setting operation is sequentially started from the security sensor 1 assigned the smallest address number, for example, "1" among the address numbers determined by the security plan. This address setting operation is automatically performed only by bringing an inspection rod (not shown) having a magnet at its tip close to the reed switch 13 of the security sensor.

In detail, when the inspection stick is brought close to the reed switch 13 of the security sensor, the reed switch 13 of the security sensor is excited and turned on, and the control of the CPU 11 starts the transmission with the monitoring device 2 and the address. A numbering request signal is generated by the CPU 11. CPU1
1 configures a predetermined communication format based on, for example, the type information of the security sensor in addition to the address request information,
The address request signal is output to the transmitter of the communication device.
As a result, the address request signal is sent to the monitoring device 2.
The transmission method during this period is a digital transmission method, but any analog transmission method, wireless transmission method, or optical transmission method may be used as long as it can send and receive data.

When the address request signal is input to the CPU 21 of the monitoring device, the CPU 21 determines the smallest address number (in this case, the first address number "1") which is not yet given and is determined. The address number and the information of the security sensor 1 are stored in the ROM 22. At the same time, this address number is formatted as an address signal and sent to the transmission line 3 via the transmitter of the communication device 25.

Since the reed switch of the crime prevention sensor 1 is in the "ON" state by the inspection stick and is in the standby state for the input of the address signal, this address signal is received only by the crime prevention sensor 1 and passes through the CPU 11. EEPRO
The address number "1" is stored in M14. At this time, since the reed switches of the other security sensors 1'are not "on", this address signal is not received. When the address number is stored in the security sensor 1, the CPU 11 controls the LED 15 provided on the outer surface of the security sensor.
Blinks the number corresponding to the address number and tells the address number set in the security sensor. In the above case,
The LED 15 blinks once.

Then, when the next security sensor 1'is operated with the inspection rod, the reed switch 1 of the security sensor is operated in the same manner as above.
3'turns on, communication is established between the sensor 1'and the monitoring device 2, and an address request signal is sent to the monitoring device 2. The CPU 21 of the monitoring device 2 allocates the currently set maximum address number, for example, the address number “2” which is incremented by one, and sends the address signal to the transmission unit 25. As a result, this security sensor 1 '
, The address number "2" is set, and LED15 'is set to 2
Flashes twice. Similarly, the address numbers of the security sensors are sequentially set by exciting the reed switches of the security sensors in the order of the numbers set in the security plan.

Next, the operation of replacing the security sensor 1'which has already been addressed will be described in the maintenance and repair of the security sensor. When the security sensor 1'is replaced, the power of the monitoring device 2 is temporarily turned off, and the security sensor 1'is replaced during that time. When the power of the monitoring device 2 is turned on again after the replacement of the security sensor 1 ', the monitoring device 2
Starts polling to call each security sensor by address number. Each existing security sensor 1 sends back a response signal in response to this call, but the replaced security sensor 1'does not send a response signal because the address number is not set yet. The monitoring device 2 identifies the address number of the replaced security sensor according to the presence or absence of this response signal and stores it in the storage device 22. In this case, it is stored that the security sensor of the address signal “2” did not respond.

The address number is set in the replaced security sensor 1'by setting the monitoring device 2 in the address setting mode and exciting the reed switch 13 'of the security sensor 1'in the same manner as described above. When the address request signal by this is sent to the monitoring device 2, the monitoring device
The address number "2" which has not responded at the time of the polling is sent to the transmitter of the communication device 2 as this address signal. As a result, the replaced security sensor 1'is
It is reset to the conventional address number "2". When multiple security sensors are to be replaced at the same time, the same operation as above is performed, but when resetting the address numbers, they are reset to the previous numbers by performing them in ascending order of the address numbers. .

Further, when the number of security sensors increases or decreases in a specific warning area, an address number is set for the increased security sensor following the maximum address number currently set, and for the decreased security sensor, For example, a lost address number may be masked as an “empty number” and idle line processing may be performed.
If each address number corresponds, the CPU of the monitoring device
It is also possible to convert only a specific address number and change it to another address number by using a maintenance tool (not shown) separately connectable to 21. This can also be applied when the address setting order is wrong at the time of address setting.

Finally, a case will be described in which after setting the address number of the security sensor, the security sensor side confirms the address number. In this case, the monitoring device 2 is set to the patrol mode, and the inspection rod is brought close to the reed switch of the crime prevention sensor to be confirmed, so that the currently set address number becomes
Can be confirmed by blinking. At this time, the address number is LE
It is represented by the number of blinking D, but when the number is large, it is 1
By changing the lighting time per turn, for example, long lighting is expressed as "5" and short lighting is expressed as "1".

In the above embodiment, the address setting for various crime prevention sensors has been described, but the present invention is not limited to this, and the address setting for control devices such as electric keys and shutters is also possible. In addition, operate the inspection rod to send a predetermined signal from the terminal to the monitoring device, select each mode of the monitoring device from the site, or operate the inspection rod to set the interlocking of the crime prevention sensor and the control device. It is also possible to apply such a method locally.

[0020]

As described above, the address number is automatically set by applying a specific operation to the security sensor, that is, a part of the terminal device, so that the trouble of address setting operation is eliminated. At the same time, the construction cost can be reduced because it is possible to easily deal with the change of the address number accompanying the change of the security plan. In addition, since the address setting operation can be performed without directly touching the setting switch, the terminal device can be hermetically sealed and can be applied to applications such as drip-proof waterproof, dust-proof, explosion-proof and acid-proof.
