It is intended for a security system including a controller for central monitoring.

According to the present invention, in such a security system, a portable wireless communication device having a transmission unit and a display unit and configured to be portable is provided. Further, the controller is provided with a transmission unit that, when receiving the detection information from the sensor device, generates a sensor test result signal including the detection information and sends the signal to the outside. Thereby, when testing the sensor device, the inspector carries the portable wireless communication device, moves to the position of the sensor device, and makes the sensor device emit an alarm. When the sensor device issues an alarm, the sensor device sends detection information including an operation signal of the sensor device and its own address signal to the controller. When receiving the received detection information, the controller creates a sensor test result signal including the detection information and sends the signal to the portable wireless communication device. The portable wireless communication device displays the received detection information of the sensor device on the display unit. The inspector can confirm from the detection information displayed on the portable wireless communication device that the sensor device that he / she tried to issue is operating normally. Therefore, the inspector can check the operation at the place where the sensor device to be tested is issued, thereby increasing the efficiency of the test operation.

In the present invention, the portable radio communication device may further include an operation unit and a transmission unit, and may transmit a test request signal for requesting the controller to transmit detection information of the sensor device. it can. In this case, the controller transmits the sensor test result information to the portable wireless communication device only when receiving the test request signal. Thus, the controller does not perform the operation of transmitting the sensor test result information except during the test, so that the traffic of the wireless communication can be reduced.

Now, the operation of the wireless security system shown in FIGS. 1 to 3 will be described. First, the operation of the system in the security mode will be briefly described. When detecting an abnormality, the sensor 1 outputs an operation signal to the wireless transmitter 2. When an operation signal is input from the sensor 1, the wireless transmitter 2 sends detection information including the operation signal of the sensor 1 and its own address signal to the outside. The controller 4 sends the sent detection information directly or by using the wireless repeater 3
When it receives the information via the PC, it emits an alarm sound, etc., displays the details of the abnormality, the location of the abnormality, etc. on its display unit, and notifies the monitoring center at a remote place.

Next, the operation of the sensor during the operation test will be described with reference to the time chart of FIG. In advance,
The location of the various sensors 1 and the transmitter 2 is planned according to the layout of the security area and the like. The RAM 413 of the controller 4 stores the location of the sensor 1 and the location of the sensor 1 corresponding to the address number of the sensor 1. The input terminal number of the connected transmitter 2, the address number of the transmitter 2, the installation location, and the like are stored.

(1) Prior to the start of the test, the inspector operates the operation unit 53 of the portable wireless communication device 5 to send a test mode setting signal to the controller 4. When the controller 4 receives the test mode setting signal via the antenna 48 and the receiving unit 45,
The control unit 41 shifts to the test mode by setting means (not shown). After that, even if sensor detection information is received,
It does not perform operations such as alarms and notifications.

(2) Next, the inspector sends a registered sensor list request signal from the portable wireless communication device 5 to the controller 4 to check the registration state of the sensor in the controller 4. (3) When the controller 4 receives this request signal,
A signal notifying a list of registered sensors (registered sensor list confirmation signal) is transmitted to the portable wireless communication device 5. The portable wireless communication device 5 displays a list of sensors on the display unit 52 from this signal.

(4) Based on the displayed list, the inspector checks the input terminal of the transmitter to which each registered sensor is connected, the result of a previously performed test, and the like. A sensor registration data request signal is transmitted from the portable wireless communication device 5 to the controller 4 for each sensor to be checked. (5) In response to this request, the controller 4 returns registration data of the sensor to the portable wireless communication device 5 by a sensor registration data transfer signal.

The inspector repeats the processes (4) and (5) to confirm data on necessary sensors. (6) The inspector sends an individual test request signal from the portable wireless communication device 5 to the controller 4 for each individual sensor to be tested in order to perform the alert test.

(7) The inspector performs an alerting operation on the sensor 1 in order to issue an alert to the sensor 1 that has requested the test. If the sensor 1 is normal, the sensor 1 issues a notification, and the transmitter 2 sends detection information of the sensor 1 to the controller 4 based on the notification. (8) Upon receiving the detection information from the transmitter 2, the controller 4 creates a sensor test result signal including the sensor number and the operation state (reporting / operation) from the detection information, and sends the sensor test result signal to the portable wireless communication device 5. And send it out. Note that the controller 4 sends the above-described terminal test result signal when there is an alarm from the sensor 1 specified by the individual test request signal, but ignores detection information from an unspecified sensor. .

In the portable radio communication device 5, the display unit 2 displays the sensor No., the operation state, and the like. The inspector should look at this display to check whether the alarm operation performed by the inspector matches the operation state of the sensor, and test that there is no abnormality in the sensor 1 and the transmitter 2. Can be. The inspector repeats the processes (6) to (8) to check the operation of the necessary sensors. Since this check can be performed by the portable wireless communication device 5 carried by the inspector, it is not necessary to return to the location of the controller 4 one by one as in the related art, and the test operation can be performed efficiently. .

(9) Upon completion of the test operation described above, the inspector inputs other commands from the portable wireless communication device 5. When this command is input to the controller 4, the controller 4 cancels the test mode and
Move to another mode. In the present invention, a wireless security system has been exemplified as an example of the security system,
It goes without saying that a wired security system in which the sensor device and the controller are connected by a wired connection may be used. At this time, the sensor device refers to a sensor that sends a signal to the controller and detects an intruder having a terminal connected by wire, a fire, or the like.
