Description

  The present invention relates to an alarm device and an alarm transmission method for transmitting detection signals of various sensors to a monitoring center in accordance with the security state of a monitoring area.

  In the security system, a plurality of types of detection devices such as an intrusion detection sensor, a fire detection sensor, and an emergency push button are installed. The detection device is configured to associate an event with the security device, and in response to the detected event, a signal representing the event is transmitted to the monitoring center, and the monitoring center determines the situation based on the transmitted signal. Necessary measures are taken.

  Therefore, when installing a security system or adding or changing a sensor, it is necessary to check whether the event detected by the sensor (intrusion, fire, emergency call, etc.) is correctly sent to the monitoring center. For inspection methods, after setting the security mode, if the sensor detects the opening or closing of a window or door, the window or door is opened or closed, and if it is a human body detection sensor, the inspector moves within the detection range of the sensor. This is done by activating each sensor. When the sensor operates normally and a detection signal is transmitted from the sensor to the security device, a notification including a signal indicating the detected event is sent from the security device to the monitoring center.

  Conventionally, the operation confirmation test performed when a sensor for detecting a fire is installed in the monitoring area is performed by setting the monitoring device to the test mode and then operating each sensor or sending the detection signal normally. (See Patent Document 1).

  Further, regarding the operation test of the security system, there is a problem in that an accurate operation test is hindered by receiving a radio wave from a device installed in another dwelling unit depending on the reception strength of the radio wave. In order to solve this, there is a technique for performing installation adjustment by monitoring the reception state of radio waves of the wireless monitoring system (see Patent Document 2). In Patent Document 2, when an ID of a system component device is registered and a signal is received from another device including the system component device, the ID included in the received signal is compared with the registered ID, and the received signal is matched. Is disclosed, and a received signal is discarded in the case of mismatch. At this time, when the all reception mode is set, all signals including an ID that does not match the registered ID are received and stored, and displayed on a monitor as necessary so that the degree of radio wave congestion can be understood. .

  Furthermore, in the conventional security system, in the alarm transmission test, the signal was sent in the security state to the monitoring center and confirmed in the same manner as usual, so that the same number of signals as the number of times the sensor detected an abnormality was received. It was sent to the monitoring center. For this reason, in order to prevent the capacity of the storage unit from being exceeded by a large amount of communication data, it is necessary to reduce the amount of information received by the monitoring center.

Therefore, as a transmission method, it is possible to set a mode for transmitting the sensor ID information and the signal type to the monitoring center, but a mode for transmitting only the signal type to the monitoring center without transmitting the sensor ID information is set. By doing so, the capacity of the storage unit was reduced.
In particular, when a large number of sensors are installed, in order to transmit all signals, the amount of information per time is reduced by transmitting the signals to the monitoring center in several times.

Japanese Patent Laid-Open No. 8-87792 JP 2006-106996 A

  However, in Patent Document 1, it is necessary to check the operation of all installed sensors individually. However, the human body detection sensor related to the security system has a wide detection range and is often installed in a passage or the like. Therefore, when the inspector moves in the building for inspection, the same sensor is detected a plurality of times, and a notification is sent to the monitoring center each time. As a result, there is a problem that communication costs for inspection increase. In addition, when a family member witnesses an inspection, there is a problem that a communication cost increases because a report is also made when the family member is detected by a sensor.

  Moreover, in the said patent document 2, even if sensor ID is registered into a monitor, it is reported also about an unrelated radio wave depending on signal strength, and since the same sensor is reported whenever it detects abnormality, There was a problem that the number of reports during the test increased and the communication cost increased.

Furthermore, as a means of reducing the amount of information, in the mode in which only the signal type is transmitted, the information contained in the signal transmitted to the monitoring center is limited to the signal type. I wasn't able to confirm if it was reported. As a result, there is a problem in that there is a possibility of leakage in the inspection.
In addition, when a large number of sensors are installed, if signals are divided and transmitted, there is a problem that labor, time and cost increase.

  The present invention has been made in view of the above, and it is possible to improve the test accuracy of the operation check while reducing the communication cost at the time of inspection, and to prevent the inspection from being leaked and the alarm transmission method. The purpose is to provide.

  In order to achieve the above object, the invention according to claim 1 is connected to a sensor that detects an abnormality in a security area to be monitored, and transmits an alarm to a monitoring center connected to a network when the sensor detects an abnormality. An alarm device that associates sensor identification information unique to the sensor with transmission information indicating whether an alarm test signal that is an alarm for an alarm transmission test has been transmitted or not transmitted to the monitoring center. When receiving a detection signal from the sensor information storage unit that stores the sensor table and the sensor, the transmission information corresponding to the sensor identification information of the sensor that transmitted the received detection signal is acquired from the sensor table and acquired. It is determined whether the transmitted information has not been transmitted. If the transmitted information has not been transmitted, the alarm test signal is transmitted only once to the monitoring center. Of the sensor that has transmitted the received detection signal in the sensor table when the alarm test signal is transmitted to the monitoring center when the alarm test signal is transmitted to the monitoring center. A transmission information updating unit that updates the transmission information corresponding to the sensor identification information to be transmitted.

  The invention according to claim 2 is the security device according to claim 1, wherein the sensor identification information is associated with a signal type indicating the type of abnormality detected by the sensor, and the alarm transmission control unit The type of the signal is transmitted only once to the monitoring center together with the alarm test signal.

  The invention according to claim 3 is executed by an alarm device that is connected to a sensor that detects an abnormality in a security area to be monitored, and that transmits an alarm to a monitoring center connected to a network when the sensor detects an abnormality. The alarm transmission method is performed, wherein the security device indicates whether sensor identification information unique to the sensor and an alarm test signal, which is an alarm for a test of alarm transmission, has been transmitted or not transmitted to the monitoring center. A sensor information storage unit that stores a sensor table that associates transmission information with the sensor information, and when receiving a detection signal from the sensor, transmits the transmission information corresponding to the sensor identification information of the sensor that has transmitted the received detection signal. It is acquired from the sensor table, it is determined whether or not the acquired transmission information is untransmitted, and if it is not transmitted, the alarm test signal is sent to the monitoring center. The alarm transmission control step that does not transmit the alarm test signal when the transmission information has already been transmitted, and the alarm table is received in the sensor table when the alarm test signal is transmitted to the monitoring center. A transmission information update step of updating the transmission information corresponding to the sensor identification information of the sensor that has transmitted the detection signal to be transmitted.

  According to the first and third aspects of the present invention, since the sensor in which the security device detects an abnormality does not transmit the alarm test signal to the monitoring center, the alarm test signal is transmitted only once. There is no need to perform this operation, and there is an effect that the operation can be accurately confirmed while reducing the communication cost during the inspection.

  According to the invention of claim 2, since the signal type is transmitted to the monitoring center only once together with the alarm test signal, the monitoring center side counts the number of times of receiving the security test signal for each signal type. Thus, it can be determined whether or not the operation confirmation has been completed for all the sensors. Therefore, according to the second aspect of the invention, it is possible to easily and accurately confirm the operation while preventing leakage during the inspection of the alarm device, and to reduce the communication cost. .

  Exemplary embodiments of a security device and an alarm transmission method according to the present invention will be explained below in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a configuration of a monitoring system according to the present embodiment.

  As shown in FIG. 1, the security system according to the present embodiment has a configuration in which a security device 100 and a monitoring center 140 are connected by a network 120 such as a telephone line, a wireless network, and the Internet.

  The security device 100 detects an abnormality in the monitoring area and reports abnormality detection information to the monitoring center 140. When the monitoring center 140 receives a report from the security device 100, the monitoring center 140 issues an instruction to the waiting security guard to go to the monitoring area, and reports to related organizations such as the police and fire department as necessary.

  Next, details of the security device 100 will be described. The security device 100 is connected to a monitoring camera 101 installed in a monitoring area, and further includes a plurality of sensors 0001a to 0001n, an operation display unit 130, an input / output unit 150, a control unit 110, and a communication control unit 160. , Mainly.

  The sensors 0001a to 0001n are, for example, an infrared sensor that detects a person based on a change in the amount of received infrared light, a shut-off sensor that detects a person when the infrared ray is blocked, and a sign sensor that detects a person due to electromagnetic wave disturbance. , And various sensors for detecting abnormalities in the security area such as a magnet sensor for detecting opening and closing of the door by a magnet.

  The operation display unit 130 includes a liquid crystal screen that displays various setting screens, operation buttons, and the like. The operation display unit 130 displays an initial setting screen and a security mode setting screen on the liquid crystal screen so that the user can perform initial setting of the security device 100. An input and setting input of various security modes for the security device 100 are performed. Here, the security mode refers to whether or not to notify a notification destination such as a monitoring center that an abnormality has been detected when an abnormality is detected in the monitoring area, or to notify that an abnormality has been detected in the monitoring area. This mode determines the operation of the security device, such as whether or not to perform it. Specifically, there are a security state, a self-security state, a home security state, a security release state, a transmission test state, and the like, and this embodiment is set to the transmission test state.

  The security state is a security mode in a state in which when the sensors 0001a to 0001n detect a malfunction and output a detection signal, the security device 100 notifies the monitoring center 140 that the malfunction has been detected.

  The transmission test state is a security mode in which a signal is transmitted to the monitoring center after the sensor installation work, and a system inspection is performed to check whether the sensor operates normally. Specifically, when the security mode is in the transmission test state, an alarm test signal that is an alarm for an operation confirmation test of alarm transmission is transmitted to the monitoring center when the sensor detects an abnormality, but the alarm test is still in progress. When the signal is not transmitted to the monitoring center, the alarm test signal is transmitted only once.

  In the self-security state, when the sensor 0001a to 0001n outputs a detection signal due to detection of an abnormality, the mobile device such as a mobile phone held by a user who is out of the office reports that the security device 100 has detected an abnormality. State security mode.

  The home security mode is a security mode in a state in which when the sensor 0001a to 0001n detects a malfunction and outputs a detection signal, the security device 100 notifies the monitoring area that the malfunction has been detected.

  In the security release state, even if the sensors 0001a to 0001n output a detection signal when an abnormality is detected, the security device 100 reports to the monitoring center 140, reports to mobile terminals, etc., reports to the monitoring area, etc. This is a security mode in which neither is performed.

  Each of these states is set in the security mode storage unit 116, which will be described later, as a security mode by the security mode switching unit 114 by a setting from the operation display unit 130 by the user or an input transmission from a portable terminal possessed by the user. .

  The input / output control unit 150 is a processing unit that controls input / output of various data by input / output control of the operation display unit 130 and input control of the sensors 0001a to 0001n. The communication control unit 160 controls communication between the security device 100 and the network 120, and specifically corresponds to a network board or the like.

  As shown in FIG. 1, the control unit 110 includes a sensor information storage unit 111, an alarm transmission control unit 112, an alarm information update unit 113, a security mode switching unit 114, a security mode storage unit 115, and a security mode acquisition. The unit 116 and the abnormality reporting unit 117 are mainly provided.

  The sensor information storage unit 111 is a storage medium such as a memory or a hard disk drive (HDD) that stores the sensor table 202.

  The sensor table 202 is a table that determines the type of abnormality detected by the sensors 0001a to 0001n and the presence or absence of transmission of an alarm test signal to the monitoring center for each of the sensors 0001a to 0001n. FIG. 2 is an explanatory diagram illustrating an example of the sensor table 202 stored in the sensor information storage unit 111 according to the present embodiment. As shown in FIG. 2, the sensor table 202 is uniquely assigned to each of the sensors 0001a to 0001n, and includes sensor IDs that are identification information for uniquely identifying the sensors 0001a to 0001n, and abnormalities detected by the sensors 0001a to 0001n. , That is, the type of the sensor signal indicating the type of the detection signal, and the transmission information indicating whether or not the alarm test signal is transmitted to the monitoring center are associated with each other. Here, the types of signals include the types of abnormal events such as intrusion, emergency, fire, and gas, but are not limited thereto. Also, as shown in FIG. 2, the transmission information indicates that the alarm test signal has already been transmitted to the monitoring center 140 by the alarm transmission control unit 112 or that the alarm test signal has not been transmitted yet. Not sent is set.

  For example, in the example of FIG. 2, for the sensor ID 0001, the signal type is set to “intrusion”, the transmission information is set to “not transmitted”, and the alarm test signal for “intrusion” is still transmitted to the monitoring center 140. It is judged that it is not done. For sensor ID 0005, the signal type is set to “emergency” and the transmission information is set to “transmitted”, and it is determined that the alarm test signal for “emergency” has already been transmitted to the monitoring center 140. The

  When the alarm transmission control unit 112 receives a detection signal from the sensor, the alarm transmission control unit 112 refers to the transmission information of the sensor table 202. If the transmission information of the sensor ID is not transmitted, the alarm transmission control unit 112 sends the alarm test signal to the monitoring center only once. It is transmitted, and if it has been transmitted, it is not transmitted.

  The alarm information update unit 113 sets the transmission information of the sensor table 202 to “transmitted” when the alarm transmission control unit 112 transmits an alarm test signal to the monitoring center 140.

  According to the security mode (or the security mode received from the mobile terminal) set in the operation display unit 103, the security mode switching unit 114 sets the current security mode to the above-described security state, self-security state, home security state, or security release state. One of the security modes is set. Specifically, the security mode switching unit 111 performs processing for switching the security mode by rewriting the current security mode stored in the security mode storage unit 112 with the security mode set in the operation display unit 103.

  The security mode acquisition unit 115 performs processing for reading the current security mode set in the security mode storage unit 112.

  The security mode storage unit 116 is a storage medium such as a memory that stores each state of the current monitoring mode of the monitoring area.

  The abnormality reporting unit 117 detects that the output signal is output from the sensors 0001a to 0001n and detects an abnormality in the monitoring area. Then, when the current security mode is set to the transmission test state and the sensors 0001a to 0001n detect an abnormality, the abnormality notification unit 114 sets the type of signal together with the alarm test signal via the communication control unit 160. Transmit (report) to the monitoring center 140. Therefore, the monitoring center 140 can confirm that alarm test signals are transmitted from all the sensors with the number of received signals.

  Next, transmission processing of an alarm test signal performed by the security method by the security device 100 according to the present embodiment configured as described above will be described. FIG. 3 is a flowchart showing a procedure for transmitting an alarm test signal. Note that the alarm test signal transmission process described below will be described on the assumption that the security mode of the alarm device 100 is set to the transmission test state. Since the alarm transmission processing when the security mode of the alarm device 100 is set to each state other than the transmission test state is the same as that of the conventional alarm device, the description thereof is omitted.

  First, when the sensors 0001a to 0001n detect an abnormality, the sensors 0001a to 0001n transmit detection signals to the alarm transmission control unit 112 (step 301).

  Next, when receiving the detection signal from the sensors 0001a to 0001n, the alarm transmission control unit 112 refers to the sensor table 202 of the sensor information storage unit 111 and acquires the transmission information of the sensor that has transmitted the detection signal (step 302). .

  And the alarm transmission control part 112 judges whether the transmission information of the sensor table 202 is untransmitted (step 303). If it has not been transmitted (step 303: Yes), the alarm transmission control unit 112 transmits the signal type together with the alarm test signal only once to the monitoring center 140 (step 304), and the transmission information update unit 113 displays the sensor table. The transmission completion is set in 202 (step 305). At this time, even if a plurality of sensors are installed in the security area, each sensor transmits only one time.

  On the other hand, if the transmission information of the sensor table 202 has been transmitted (step 303: No), the alarm transmission control unit 112 does not transmit the alarm test signal to the monitoring center 140 (step 306).

  Thus, in the security device 100 according to the present embodiment, when the sensor reports an abnormality, the alarm transmission control unit 112 refers to the transmission information of the sensor from the sensor table 202 of the sensor information storage unit 111 and In the case of transmission, an alarm test signal is transmitted to the monitoring center only once. For this reason, even if a detection signal is transmitted a plurality of times from the same sensor, a notification is not sent to the monitoring center each time, so the communication cost can be reduced.

  Further, in the security device 100 according to the present embodiment, the sensor ID and the signal type are associated with each other, and when the sensor reports an abnormality, the alarm transmission control unit 112 only once with the alarm test signal. The type of signal is transmitted to the monitoring center 140. Thereby, it can be confirmed from the type of signal and the number of transmissions which signal type is reported and whether it is reported from all sensors. For this reason, it is possible to easily and accurately confirm the operation of all the sensors while reducing the communication cost and preventing leakage at the time of inspection.

It is explanatory drawing which shows an example of the sensor information storage part concerning this Embodiment. It is a flowchart which shows the transmission procedure of an alarm test signal.
