Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wireless security system in which an address of a wireless transmitter can be easily registered in a controller and a wireless relay device in a security system using a wireless system.
[0002]
[Prior art]
Conventionally, various security systems using a wireless system have been proposed.
In these conventional wireless security systems, as shown in FIG. 1, wireless transmission connected to an intrusion sensor 1 installed on a window or door, a fire sensor 2 for detecting a fire, a gas sensor 3 for detecting a gas leak, etc. The controller 7 receives and monitors the radio signals from the machines 4, 5, 6 and reports to the remote security center (not shown) via the communication line when an intrusion abnormality, fire abnormality, gas leak, etc. is detected. It is configured to.
[0003]
When such a wireless security system is installed in a multi-layered building, for example, when the controller 7 is installed on the first floor and the wireless transmitters 4 to 6 are installed on the third floor, the wireless transmitter 4 is installed. In some cases, the controller 7 may not be able to receive the wireless signal transmitted from ˜6 directly due to an obstacle or the like on the way. In this case, at least one radio repeater 8 for relaying radio signals from the radio transmitters 4 to 6 to the controller 7 is installed on the second floor, for example.
[0004]
The controller 7 registers and stores the address code individually possessed by the wireless transmitter and the wireless repeater in order to determine which wireless transmitter and wireless repeater received the signal. .
As a conventional method of registering the address codes of the wireless transmitters 4 to 6 and the wireless relay device 8 in the controller 7, the various sensors 1 to 3, the wireless transmitters 4 to 6, and the wireless relay device 8 are installed in the building or its After the installation is completed at a place deemed necessary in the vicinity, first, the controller 7 and the wireless relay device 8 are set to the registration mode by the portable setting transmitter 9 or directly by operation of a dip switch or the like. Next, a registration signal including an address signal of the wireless relay device 8 to be registered is transmitted from the wireless relay device 8 to the controller 7 to register the address of the wireless relay device 8 in the controller 7. Next, the wireless relay device 8 registers the addresses of the wireless transmitters 4 to 6 to be relayed by the wireless relay device. Next, in a state where the controller 7 is continuously set to the registration mode, in this registration mode, a registration signal of the radio transmitter is transmitted from each radio transmitter to be registered to the radio relay 8. In this case, the registration signal includes the address signal of the wireless transmitter to be registered and transmits it to the wireless relay device 8. Next, the wireless repeater 8 adds the address signal of this wireless repeater to the registration signal from the wireless transmitter to be relayed that has been registered in advance and transmits it to the controller 7 to register the address of the wireless transmitter in the controller 7. Like to do.
[0005]
Thus, conventionally, after installing a wireless repeater in advance and registering the address of the wireless transmitter to be relayed in the wireless repeater, relaying the wireless repeater and registering the address of the wireless transmitter in the controller Was.
[0006]
[Problems to be solved by the invention]
However, whether or not a wireless repeater is required depends on the building situation, so even if a wireless repeater is installed in advance, it will not change until the actual wireless repeater is installed and wireless transmission is performed. I don't know if this is necessary. In some cases, it may be possible to directly transmit from the wireless transmitter to the controller 7, and in this case, the installed wireless relay device is wasted. Alternatively, it may be necessary to install two or more radio repeaters because one installed radio repeater cannot relay radio signals from all radio transmitters. In such a case, it is necessary to make a change such as deleting the address of the wireless transmitter to be registered in the second wireless relay device from the one wireless transmitter registered as a unit. Therefore, if the wireless transmitter address is registered after being previously installed in the wireless repeater as in the prior art, and then the wireless transmitter address is registered in the controller via the wireless repeater, this is unnecessary. Each time a new wireless repeater is installed or the registration details are changed, the previously registered work is wasted, and re-registration of the wireless transmitter to be relayed to that wireless repeater is necessary. There was a problem that the work was complicated.
[0007]
An object of the present invention is to provide a wireless security system including a wireless repeater that solves the above-described problems, eliminates unnecessary installation of wireless repeaters and waste of registration work, and facilitates registration work. is there.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a wireless transmitter connected to various sensors installed in a security area, and a wireless relay that relays a wireless signal transmitted from the wireless transmitter. And a controller for receiving a radio signal transmitted from the radio transmitter and the radio repeater, wherein the radio repeater receives a predetermined radio signal from the radio transmitter. If the command is a registration command, the relay command is transmitted to the controller as it is, and if it is not the predetermined registration command, only the radio signal from the registered radio transmitter is relayed to the controller. Is a wireless security system characterized by
[0009]
Since registration with the wireless relay device is performed after registration with the controller, useless registration work such as registering an originally unnecessary wireless relay device with the controller becomes unnecessary.

[0013]
FIG. 5 is a time sequence diagram illustrating the wireless security system according to the embodiment of the present invention. FIG. 6 is a flowchart for explaining the operation of the portable setting transmitter 9 in FIG. FIG. 7 is a flowchart for explaining the operation of the wireless repeater 8 in FIG. FIG. 8 is a flowchart for explaining the operation of the controller 7 in FIG. The portable setting transmitter 9 is also referred to as a patrol button, and is usually used by a guard for setting each device.
[0014]
The operation of the wireless repeater according to the embodiment of the present invention will be described with reference to FIGS.
First, the portable setting transmitter 9 is operated to transmit a registration mode setting signal and the controller 8 receives the signal, or the dip switch or the like in the operation unit 42 is operated, so that the controller 7 is brought into the registration mode state. ((1) in FIG. 5, step 81 in FIG. 8). Next, by operating the portable setting transmitter 9, a device registration request command is transmitted from the portable setting transmitter 9 to the wireless relay device 8 ((2) in FIG. 5, step 51 in FIG. 6). . This device registration request command is a command that requests the controller 7 to wait for registration of a wireless transmitter or a wireless relay device. The wireless repeater 8 receives this device registration request command from the portable setting transmitter 9 (step 701 in FIG. 7). The wireless repeater 8 determines the type of the received signal (steps 702, 707, and 708 in FIG. 7), and in this case, since it is a registration request command from the portable setting transmitter 9 registered in advance, FIG. The process proceeds to step 706 of FIG. 7, and the registration request command from the portable setting transmitter 9 is simply relayed to the controller 7 ((3) in FIG. 5). The controller 7 receives the relayed device registration request command (step 82 in FIG. 8). As a result, the controller 7 is ready to accept registration commands from the wireless transmitter and the wireless relay device 8.
[0015]
Next, a registration command is transmitted from the wireless transmitter to be registered to the wireless relay device 8 ((4) in FIG. 5). The registration command includes a code indicating a registration command, a model to be registered (in this case, a wireless transmitter), an identification number (address), and the like. When the wireless repeater 8 receives this registration command from the wireless transmitter, it determines the received signal in steps 702 and 703. In this case, since it is a registration command from the wireless transmitter, it proceeds to step 704, and the registration command is used as it is. Relay to the controller 7 ((5) in FIG. 5). Conventionally, the registration command from the wireless transmitter is registered in the wireless relay device 8 at this stage, but in the present invention, the registration command is simply relayed without registration in the wireless relay device 8. If the relay operation cannot be performed by this wireless relay device 8 at this stage, another wireless relay device 8 may be installed at a more appropriate position. Since the registration work of the wireless transmitter with respect to the wireless relay device 8 has not been done yet, the registration work is not wasted as in the conventional case by changing the wireless relay device 8. Further, if it is possible to transmit a signal directly from the wireless transmitter to the controller 7 without using the wireless relay device 8 at this stage, it can be determined that the wireless relay device 8 need not be installed. 8 is not wasted.
[0016]
The controller 7 receives the relayed registration command from the wireless relay device 8 (step 83 in FIG. 8), and registers the address of the wireless transmitter in the controller 7 in accordance with the received registration command (step 84 in FIG. 8). .
Next, the controller 7 transmits a device registration confirmation command to the wireless relay device 8 ((6) in FIG. 5, step 85 in FIG. 8), and when the wireless relay device 8 receives this device registration confirmation command (in FIG. 7). Steps 701, 702, 707, 710, 711) This device registration confirmation command is relayed to the portable setting transmitter 9 ((7) in FIG. 5 and step 712 in FIG. 7). The portable setting transmitter 9 receives this device registration confirmation command (step 62 in FIG. 6). When there is another wireless transmitter to be registered, the portable setting transmitter 9 repeats the operation from (2) of FIG. 5 again, the wireless relay device 8 repeats the operation after step 701, and the controller 7 The operations in steps 701 to 86 are repeated.
[0017]
When the registration of the addresses of all the wireless transmitters is completed in the controller 7, the controller 7 transmits all the addresses of the registered wireless transmitters to the wireless relay device 8 (step 87 in FIG. 8). Then, the wireless repeater 8 registers the received address of the wireless transmitter in the wireless repeater 8 (steps 713 and 714 in FIG. 7).
This completes the registration process. Thereafter, when the wireless repeater 8 receives a signal from the wireless transmitter, and it is determined in steps 702 and 703 in FIG. 7 that the signal is not a registration command from the wireless transmitter, in step 705, the received signal is In step 714 of FIG. 7, it is determined whether or not the signal is from a registered wireless transmitter. If the signal is from a registered wireless transmitter, the signal is determined as an alarm signal during normal operation other than during registration. In step 706, the self address is added to the controller 7 for relay transmission. When the controller 7 receives this signal, it transmits the signal to a control center (not shown).
[0018]
【The invention's effect】
As is clear from the above description, according to the present invention, when registering the address of the wireless transmitter to be relayed to the wireless repeater in the wireless security system, the address of the wireless transmitter is first registered in the controller. Later, since it was registered in the wireless repeater, it was registered again when another wireless repeater was installed after installing a wireless repeater that was originally unnecessary, or after registering for one wireless repeater. There is an effect that complicated registration work such as work is unnecessary.
