Description

  The present invention relates to an equipment signal inspection adapter and an equipment signal inspection method.

  Conventionally, when equipment abnormalities are detected by human sensors, fire alarms, elevator failure alarms, etc., installed in the monitoring area, the security device provided in the equipment can be used by a home alarm or equipment user by an alarm, etc. A remote security system is generally known for notifying or reporting an abnormality to a monitoring center.

  It is necessary to periodically check whether such a remote security system is operating normally. However, the conventional security device sequentially sends notifications (inspection signals) from all sensors to the monitoring center at the time of inspection, so the number of notifications becomes large and hinders the original monitoring work, and a telephone line is used. In the remote security system, every time a report is made by inspection, one of the lines used to receive an alarm on the monitoring center side is occupied, and there is a problem that a large communication cost is incurred for the inspection. It was.

  On the other hand, Patent Document 1 discloses a technique related to a fire receiver provided with a periodic inspection mode switch. When the periodic inspection mode switch is operated, the fire receiver becomes a functional state necessary for the periodic inspection. Since the operation with the fire hydrant is stopped and the accumulation of the signal is released, the cost for the inspection work can be reduced.

  Patent Document 2 discloses a technique related to a remote monitoring system including a terminal device that does not send abnormality detection information to a receiving device when it is set as a maintenance check operation.

Japanese Patent Laid-Open No. 5-28374 JP-A-10-194620

  Exemplary embodiments of an equipment signal inspection adapter and an equipment signal inspection method according to the present invention will be explained below in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a diagram for explaining a remote monitoring system in which an equipment signal inspection adapter 1 according to a first embodiment is installed. An equipment signal inspection adapter (hereinafter referred to as an inspection adapter) 1 according to the present embodiment includes a human sensor, a fire alarm, and other sensors a and b provided in a monitoring area 3 as shown in the figure. ,... Sensor n (hereinafter referred to as sensor 4 unless otherwise specified) and security device 5 are installed.

  During normal security, when the sensor 4 detects an abnormality such as a suspicious person or a fire, it sends a detection signal notifying the abnormality to the inspection adapter 1. The inspection adapter 1 sends the detection signal to the security device 5 when receiving the detection signal. When the security device 5 receives the detection signal, the security device 5 notifies the monitoring center 7 of the abnormality via the network 6 including the Internet and a telephone line.

  On the other hand, at the time of inspection, whether or not the sensor 4 operates normally is checked by a person in charge of inspection such as an equipment management company or a security company. When the sensor 4 operates normally by this inspection and detects an abnormality, the above detection signal is sent to the inspection adapter 1. The inspection adapter 1 sends the received detection signal to the security device 5 only for the first time. When the security device 5 receives the detection signal, the security device 5 notifies the monitoring center 7 of the detection by the sensor 4 via the network 6.

  FIG. 2 is an external view of the inspection adapter 1 according to the first embodiment. The inspection adapter 1 is provided with one input port 8 for receiving a detection signal from the wired sensor 4 for each sensor 4. In addition, output ports 9a and 9b for transmitting the received detection signals are provided for the security device 5 connected by wiring. The inspection adapter 1 includes a switching button 12 that switches between a security state and an inspection state by pressing a button when starting the inspection, a display panel 10 that displays the inspection state by a liquid crystal panel, and the like. And a display lamp 11 for displaying that the vehicle is in the inspection state by lighting. Details will be described later.

  FIG. 3 is a block diagram illustrating a functional configuration of the inspection adapter 1 according to the first embodiment. As illustrated, the inspection adapter 1 according to the first embodiment includes a detection signal input unit 13, a detection signal output unit 14, a guard state switching unit 15, an inspection signal output unit 16, and an operation display control unit 17. And an inspection management control unit 18, an inspection DB (database) 19, an input port 8, and output ports 9a and 9b.

  The detection signal input unit 13 receives the detection signal sent from the sensor 4 provided in the monitoring area 3 via the input port 8 and sends the detection signal to the detection signal output unit 14 or the inspection signal output unit 16 described later. Send it out.

  The security state switching unit 15 switches the inspection adapter 1 from the security state to the inspection state when the switching button 12 is operated by the user.

  Here, the security state is a state of the inspection adapter 1 that transmits the received detection signal to the security device 5 as it is when the sensor 4 detects an abnormality and sends a detection signal. It is a normal security state in which the security device 5 that has received the message reports the abnormality to the monitoring center 7.

  The inspection state means that the inspection adapter 1 detects the security device 5 only for the first time when the detection signal is received when the sensor 4 operates normally for inspection work and sends a detection signal. This is a state to send a signal.

  Specifically, the security state switching unit 15 is provided in the inspection adapter 1 so that the detection signal input unit 13 and the inspection signal output unit 16 are connected when the switch button 12 is pressed by the user. Switch the connection of the switching circuit.

  Thereby, in the inspection state, the detection signal input to the detection signal input unit 13 is output using the output port 9b provided in the inspection signal output unit 16 and a dedicated inspection line connected to the output port 9b. It is sent to the security device 5.

  In addition, when the user presses the switch button 12 again after the inspection of the sensor 4 is completed, the security state switching unit 15 ends the inspection state and returns to the security state. Specifically, the guard state switching unit 15 switches connection of a switching circuit or the like provided in the inspection adapter 1 so that the detection signal input unit 13 and the detection signal output unit 14 are connected.

  Thereby, in the security state, the detection signal input to the detection signal input unit 13 is output from the output port 9a provided in the detection signal output unit 14 and the security line connected to the output port 9a as needed. To the security device 5. That is, when the sensor 4 senses an abnormality, it returns to the security state in which all notifications are sent to the monitoring center 7.

  In addition, after switching to the inspection state, the security state switching unit 15 determines that the inspection state has ended when the detection signal is not input from the sensor 4 even after a predetermined time has elapsed, and switches to the security state.

  When a detection signal is input from the sensor 4 in the security state, the detection signal output unit 14 sends the detection signal to the security device 5 using the output port 9a and a line connected to the output port 9a.

  When the detection signal is input from the sensor 4 in the inspection state, the inspection signal output unit 16 uses the output port 9b and the line connected to the output port 9b to detect the detection signal to the security device 5 only once. Is sent out.

  In the monitoring center 7, the detection signal received from the line connected to the output port 9b is monitored as a report in the inspection work.

  When the operation state control unit 17 is switched to the inspection state by the security state switching unit 15, as shown in FIG. 2, a message such as “inspection” is displayed on the display panel 10, and the display lamp 11 is turned on. Illuminates to indicate to the user that the inspection adapter 1 is in the inspection state. The operation display control unit 17 ends the message display such as “inspection” displayed on the display panel 10 when the inspection state is ended by the security state switching unit 15 and returned to the security state, and further, The display lamp 11 is turned off.

  Further, when a detection signal is input from the sensor n in the inspection state, the operation display control unit 17 displays a message such as “inspection OK” on the display panel 10 as shown in FIG. Is displayed to the user. Thus, each sensor 4 can be normally operated by checking the message displayed on the display panel 10 of the inspection adapter 1 without reporting the detection signal of the sensor 4 to the monitoring center 7 via the security device 5. It is possible to confirm whether or not it is operating.

  Further, when a detection signal is input from the sensor n in the security state, the operation display control unit 17 displays a message such as “alarm” on the display panel 10 as shown in FIG. Display to the user that there is an alarm. As a result, when an abnormality in the monitoring area is detected, it is possible to deal with the abnormality prior to contact or handling from the monitoring center 7.

  When the detection signal is input to the detection signal input unit 13 in the inspection state, the inspection management control unit 18 receives the sensor n that has transmitted the detection signal and the input of the detection signal from the sensor n to the inspection DB 19. Is stored in association with the fact.

  When the detection signal is input to the detection signal input unit 13 in the inspection state, the inspection DB 19 associates the sensor n that has transmitted the detection signal with the fact that the detection signal has been input from the sensor n. Save and save.

  Next, a procedure of processing performed by the inspection adapter 1 of the present embodiment will be described. FIG. 6 is a flowchart for explaining the procedure of the inspection process executed by the inspection adapter 1 according to the first embodiment.

  The security state switching unit 15 determines whether or not the switching button 12 has been pressed by the user (step S1). When the switch button 12 is not pressed (step S1; No), the process returns to step S1. When the switch button 12 is pressed (step S1; Yes), the guard state switching unit 15 switches from the guard state to the inspection state, and the detection signal input unit 13 and the inspection signal output unit 16 are connected as described above. (Step S2).

  Thereafter, the detection signal input unit 13 determines whether or not a detection signal is input from the sensor 4 (step S3), and waits for input while there is no input (step S3; No). When a detection signal is input from the sensor n to the detection signal input unit 13 (step S3; Yes), the operation display control unit 17 displays on the display panel that the operation of the sensor n is normal (step S4). In addition, the inspection management control unit 18 stores and saves in the inspection DB 19 that the sensor n that has transmitted the detection signal and the fact that the sensor n has detected an abnormality and has transmitted the detection signal (step S4).

  Further, the inspection signal output unit 16 determines whether or not it is the first detection signal after shifting to the inspection state (step S5), and when it is the first detection signal (step S5; Yes), the received detection signal is output. The information is sent to the security device 5 (step S6), and the monitoring center 7 confirms whether the notification is communicated. If the detection signal is not the first time (step S5; No), even if the detection signal is input, the detection signal is not sent to the security device 5, and the process proceeds to step S7.

  After the first detection signal is sent to the security device 5, the next sensor 4 is checked (step S7). It is determined whether or not there is a sensor 4 to be inspected (step S8). If there is a sensor 4 to be inspected (step S8; Yes), the process proceeds to step S3, and steps S3 to S3 are performed until all the sensors 4 are inspected. Perform the inspection work of S7.

  When all the sensors 4 have been inspected and there is no sensor 4 to be inspected (step S8; No), the security state switching unit 15 determines whether or not the switching button 12 has been pressed again (step S9). If not, it waits for being pressed (step S9; No). When the switch button 12 is pressed, or when a detection signal is not input and the switch button 12 is not pressed for a predetermined time (step S9; Yes), the security state switching unit 15 is in an inspection state. To return to the security state (step S10).

  As described above, the inspection adapter 1 according to the present embodiment sends the detection signal to the alarm device 5 only once in the inspection state to confirm the communication with the monitoring center 7, and otherwise checks the display panel 10. The result of the inspection is displayed, and the result of the inspection is stored and saved in the inspection DB. Thereby, unnecessary reports to the monitoring center 7 can be reduced, and the burden of monitoring work at the monitoring center 7 can be reduced. Moreover, it becomes possible to immediately confirm the response of the sensor 4 by the inspection adapter 1 installed in the monitored facility during the inspection work.

  In addition, as described above, the inspection adapter 1 according to the present embodiment makes a distinction between the line used in the security state and the line used in the inspection state, so that the monitoring center 7 reports the inspection operation and the security state. Thus, it is possible to distinguish and monitor the notification received from the line connected to the output port 9a, and the original monitoring operation can be performed smoothly without being confused with the original notification.

  In addition, as described above, the inspection adapter 1 according to the present embodiment switches to the security state when the detection signal is not input from the sensor 4 after a certain period of time has elapsed after switching to the inspection state. In this way, when the user forgets to operate the switching button 12, it is possible to automatically return to the security state, and the safety of the remote monitoring system is maintained even if the inspection adapter 1 is installed. There is an effect that can be done.

S2). The detection signal input unit 13 determines whether or not a detection signal is input from the sensor 4 (step S3). When the detection signal is input (step S3; Yes), the operation display control unit 17 displays the sensor n on the display panel. A message indicating that the operation is normal is displayed (step S4). In addition, the inspection management control unit 18 stores and saves in the inspection DB 19 that the sensor n that has transmitted the detection signal and the fact that the sensor n has detected an abnormality and has transmitted the detection signal (step S4).

  The inspection adapter 2 moves to the next inspection work of the sensor 4 (step S7). It is determined whether or not there is a sensor 4 to be inspected (step S8). If there is a sensor 4 to be inspected (step S8; Yes), the process proceeds to step S3, and steps S3 to S3 are performed until all the sensors 4 are inspected. Perform the inspection work of S7.

  When all the sensors 4 have been inspected and there is no sensor 4 to be inspected (step S8; No), the security state switching unit 15 determines whether or not the switching button 12 has been pressed again (step S9). If not (step S9; No), it waits to be pressed. When the switch button 12 is pressed, or when the detection signal is not input and the switch button 12 is not pressed for a predetermined time (step S9; Yes), the inspection signal output unit 26 displays the security device 5 The detection signal is transmitted only once at a time (step S11). Thereafter, the guard state switching unit 15 ends the inspection state and returns to the guard state (step S10).

  As described above, the inspection adapter 2 according to the present embodiment sends a detection signal to the security device 5 only once and notifies the monitoring center 7 when the inspection state ends. In this way, since the line can be used only once at the end of the inspection, it is not necessary to occupy the line for notification during the inspection work. Etc. can be used as usual.
