Description

  The present invention accepts a security status signal detected by one or a plurality of sensors, and automatically transmits an abnormal status detection signal indicating the abnormal status to the outside when a security status error is detected by the status signal. The present invention relates to a security system control device.

  As a control device of this type of security system, for example, as disclosed in the following Patent Document 1, various sensors such as a human sensor, a gas leak sensor, a temperature sensor, a smoke sensor, a lighting sensor, and a lock sensor are available. Each sensor is connected to a control device consisting of a personal computer installed in the house via an input / output interface, and a modem or terminal adapter for communication connection with the outside. The communication interface is connected to an external communication device such as a mobile phone of a resident of the house or a server computer of a security company through the communication interface and a public telephone line or a mobile phone line. is there.

  In the security system control device disclosed in Patent Document 1 below, when only a wired communication line such as a public telephone line is used as a means for communication with the outside, it is illegal to enter the house from the outside. The intruder disconnects the cable communication line before the intrusion and disables the detection of sensor abnormality due to the intrusion to the external communication device such as the security company's server computer. It may not function.

Therefore, as disclosed in Patent Document 2 below, a wired line diagnostic unit for diagnosing abnormalities in a wired communication line is provided, and when the wired line diagnostic unit detects an abnormality, a communication line used for reporting an abnormality is detected from the wired communication line. There is a configuration for avoiding a communication malfunction caused by artificial interruption of a wired communication line by switching to a wireless communication line.
JP 2000-251181 A JP-A-8-63689

  However, in the security system disclosed in Patent Document 1 or 2, power supply (power feeding) from an outdoor power source such as a commercial power source to a control device that detects an abnormality of the security system and notifies the abnormality detection to the outside. If is stopped, the entire control device will not function. Therefore, if an illegal intruder from outside cuts off an electric circuit (power line, etc.) that feeds power to the control device before the intrusion, regardless of whether the abnormality report route to the outside is a wired communication line or a wireless communication line, This will result in failure reporting.

  In order to solve the above problems, it is conceivable to use a power supply device that can be charged indoors and can be installed indoors without using a commercial power supply to supply power to the security system. When depending on the power supply from the apparatus, a large capacity is required as the electric capacity of the power supply apparatus, the equipment cost increases, and the control apparatus including the power supply apparatus becomes large.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a security system control device capable of maintaining normal operation by detecting an individual artificial power supply stop to the security system. .

  In order to achieve this object, a first characteristic configuration of a control device of a security system according to the present invention is a status signal indicating each of the security states from one or more sensors that individually detect one or more security states. When a security status abnormality is detected by the status signal, the security system control device automatically transmits an abnormal status detection signal indicating the abnormal status to the outside, and constantly supplies power to the control device. A power supply stop detection unit that monitors a power supply state from a normal power source and generates a power failure detection signal for notifying the outside of the power supply stop state when detecting a power supply stop from the normal power source, and the normal power source Emergency power supply capable of temporarily supplying power to the control device when the power supply of the power supply stops, the power failure detection signal and the abnormal state detection Lies in comprising and a communication interface unit capable of transmitting using a predetermined communication line to a predetermined external receiving device No..

  According to the first characteristic configuration described above, even when the power supply from the normal power supply that constantly supplies power to the control device such as a commercial power supply is intentionally cut off by an illegal intruder, the emergency power supply device can supply power to the control device. Therefore, any sensor detects the intruder's intrusion and accepts a state signal indicating the intrusion state (one of the security states), and the state signal can detect an abnormality in the security state, An abnormal state detection signal indicating the abnormal state can be automatically transmitted from the communication interface unit to the external receiving device. As a result, even if the power supply from the normal power source is obstructed by an illegal intruder, the abnormality of the security state can be normally reported to the outside, and the security / disaster prevention performance of the security system can be improved. Furthermore, even if an abnormality in the security state is not detected by the status signal output by the sensor, the power supply stop detection unit generates a power failure detection signal, and the power failure detection signal is transmitted from the communication interface unit to the external receiving device. For example, security personnel such as security companies and users of security systems are dispatched to the site, so that it is possible to confirm whether the power supply stoppage is artificial due to illegal intruders or other factors, Anomaly detection function by the security system is further ensured.

  Here, the emergency power supply device only needs to operate for a certain period of time when a power failure is detected and can transmit a power failure detection signal or an abnormal state detection signal to the outside, so its power supply capability may be limited. For example, the emergency power supply device may not necessarily be a rechargeable secondary battery but may be a fully used primary battery. Therefore, it is possible to improve the security and disaster prevention performance of the security system by using a small and inexpensive device regardless of whether or not the emergency power supply can be charged.

  In the second feature configuration, in addition to the first feature configuration, when the power supply from the normal power supply is stopped, the cause of the power supply stop is the individual artifact of the power supply system from the normal power supply to the control device. The communication interface unit includes a power failure cause analysis unit that determines whether or not the power supply is stopped due to an individual (human and artificial) interruption, and generates a human power failure detection signal when the cause of the power supply stop is individual artificial. However, the artificial power failure detection signal can be transmitted to the external reception device using the predetermined communication line.

  According to the second feature configuration, the power failure detection signal generation unit generates a power failure detection signal, the power failure detection signal is transmitted from the communication interface unit to the external receiver, and the power failure cause analysis unit Is generated by an artificial human power failure detection signal, and the human power failure detection signal is transmitted from the communication interface unit to the external receiver. It is possible to immediately confirm whether or not it is outside. Therefore, even if an abnormality in the security state is not detected by the state signal output from the sensor, the abnormality in the security state can be reliably detected by the artificial power failure detection signal, and the security system's crime prevention performance can be further improved. become.

  In the third feature configuration, in addition to the second feature configuration, the power failure cause analysis unit receives and stores an input of a scheduled power failure scheduled time of the normal power supply, and the normal power failure storage unit A current amount storage unit is provided for detecting and storing the amount of current passing through the safety device interposed between the power source and the control device.

  According to the third feature configuration described above, the case where the power supply is stopped due to the planned power failure of the normal power source and the case where the safety device is operated and the power failure occurs exceeding the allowable current capacity of the safety device are identified. Thus, it is possible to detect a blackout other than the planned blackout of the normal power supply and the blackout caused by the operation of the safety device. That is, it is possible to detect with high probability a case where power supply is intentionally stopped by an illegal intruder or the like. Specifically, the planned power outage storage unit accepts and stores an input of the scheduled power outage scheduled time of the security system by the user of the security system, for example. It can be judged as a power failure. In addition, the current amount storage unit sequentially detects and stores the amount of current passing through the safety device, so that if the current amount immediately before the power failure is approaching the allowable current capacity, the power failure is safe. It can be determined that there is a high possibility of a power failure due to the operation of the device.

  In the fourth feature configuration, in addition to the second or third feature configuration, the predetermined communication line performs wireless communication with the communication interface unit of the control device within a certain geographical range. At least a wireless communication line including a repeater to perform, wherein the communication interface unit transmits the power failure detection signal to the repeater, and the repeater is within the certain geographical range. When the power failure detection signal is received from the communication interface unit of the control device, a second power failure detection signal indicating the reception state of the repeater is received from the repeater, and the power failure cause analysis unit is configured to receive the second power failure cause analysis unit. When a power failure detection signal is received, it is determined that the cause of the power supply stop is not individual artificial.

  According to the fourth characteristic configuration described above, another control device within the same geographical range detects a similar power supply stop, that is, a similar power supply stop state occurs in a plurality of control devices. Since it is possible to confirm this, it is possible to determine whether the cause of the power supply stop is individual artificial or not from the situation of the other control device. In other words, it is unlikely that the interruption of the power supply from the normal power source by an illegal intruder will occur at the same time, and the power failure that occurs at the same time will also be applied to other control devices within the same geographical area. Based on the premise that there is a high possibility of a power failure of the normal power supply itself that supplies it, when the second power failure detection signal is received, it is determined that the cause of the power supply stop is not artificial in each security system be able to. As a result, when the cause of the power supply stop is not individual artificial, it is possible to cope with, for example, limiting the external receiving device that is the transmission destination of the power failure detection signal to only users of the security system.

  In the fifth feature configuration, in addition to any one of the feature configurations described above, the predetermined communication line includes at least two communication lines, a wired communication line and a wireless communication line, and disconnects the wired communication line. A line disconnection detection unit for detecting, the communication interface unit normally communicates with the external receiving device using the wired communication line, and the line disconnection detection unit detects disconnection of the wired communication line. When detected, the communication line is switched to the wireless communication line.

  According to the fifth feature configuration, since the communication cost using the wired communication line is generally lower than the communication cost using the wireless communication line, the communication cost with the external receiving device is kept low, and some When a wired communication line is disconnected due to a cause, a wireless communication line can be used as a backup line, and the wireless communication line is difficult to block the communication path by illegal intruders. The crime prevention and disaster prevention performance can be improved.

  In the sixth feature configuration, in addition to the fifth feature configuration, the line disconnection detection unit periodically communicates with the external reception device via the wired communication line, and from the external reception device The disconnection of the wired communication line is detected based on the response signal.

  According to the sixth feature configuration, the disconnection of the wired communication line can be detected regardless of the communication method of the wired communication line and the type of the communication cable, and even if the type of the wired communication line differs for each control device. The line disconnection detection unit can use the same disconnection detection algorithm.

  In the seventh feature configuration, in addition to the sixth feature configuration, the line disconnection detection unit includes a planned reception stop storage unit that receives and stores an input of a planned reception stop time from the external reception device. is there.

  According to the seventh feature, when the disconnection of the wired communication line is determined due to the abnormality of the response signal from the external receiving device, the case where the abnormality of the response signal is due to the planned reception stop of the external receiving device. Therefore, the disconnection of the wired communication line can be detected by distinguishing the disconnection state that should be detected due to the physical disconnection of the communication cable of the wired communication line and the planned normal disconnection state. That is, it is possible to detect with high probability a case where a wired communication line is intentionally disconnected by an illegal intruder or the like. Specifically, the planned reception stop storage unit accepts and stores the input of the planned reception stop time of the external receiving device by the user of the security system, for example, and responds to the disconnection of the wired communication line at that time. When it is detected due to a signal abnormality, it can be determined that the planned wired communication line is disconnected.

  In the eighth feature configuration, in addition to the fifth, sixth, or seventh feature configuration, when the line disconnection detection unit detects a disconnection of the wired communication line, to notify the disconnection state to the outside. A disconnection detection signal generation unit for generating a disconnection detection signal of the first communication unit, wherein the communication interface unit can transmit the disconnection detection signal to the external reception device using the wireless communication line.

  According to the eighth characteristic configuration, even when the external reception device does not receive the abnormal state detection signal via the wireless communication line, the reception of the disconnection detection signal notifies that the wired communication line has been disconnected for some reason. Therefore, for example, when security personnel such as security companies or users of security systems are dispatched to the site, the cause of the disconnection state can be elucidated, and it is artificial due to illegal intruders Will be able to discover security anomalies early.

  In the ninth feature configuration, in addition to the eighth feature configuration, the wireless communication line includes a repeater that performs wireless communication with the communication interface unit of the control device within a certain geographical range. The communication interface unit transmits the disconnection detection signal to the repeater, and the relay detects the disconnection from the communication interface unit of the other control device within the certain geographical range. When a signal is received, the second disconnection detection signal indicating the reception state of the repeater is received from the repeater, and the external reception device that is the transmission destination of the disconnection detection signal is changed or added. .

  According to the ninth feature, the other control device within the same geographical area detects the disconnection of the same wired communication line, that is, the same disconnection state occurs in the plurality of control devices. Therefore, it is possible to determine whether or not the disconnection of the wired communication line is made individually and artificially for a specific security system from the situation of the other control device. That is, the disconnection of the wired communication line by the illegal intruder is unlikely to occur at the same time, and the disconnection of the wired communication line that occurs at the same time occurs in other control devices within the same geographical range. If the second disconnection detection signal is received based on the assumption that there is a high possibility of disconnection due to some cause of the connected wired communication line itself, the cause of the disconnection of the wired communication line is an individual artifact in each security system. It can be judged that it is not appropriate. As a result, when the cause of the disconnection of the wired communication line is not individual artificial, it is possible to cope with, for example, limiting the external reception device that is the transmission destination of the disconnection detection signal to only users of the security system.

  As the wireless communication line 41, use of a PHS line, a specific low power radio, or the like is assumed. In the present embodiment, the wireless communication interface unit 6B performs wireless data communication with the wireless master device 43 of the wireless communication line 41, and the wireless master device 43 is connected to the Internet 45 via the relay station 44. As another embodiment, the wireless master device 43 may be switched to a wired communication line and connected to the Internet 45.

  As the external receiving devices 30 and 31, a security company server device 30 that manages the security system 1 and a user terminal 31 that can be used externally by a user of the security system 1 such as a mobile phone having a data communication function are assumed. .

  The user interface unit 7 transmits / receives data to / from a user terminal 14 such as a personal computer connected to the computer network 4 using a predetermined communication protocol.

  The abnormal state detection unit 8 analyzes the state signal S received from each sensor 3 via the sensor interface unit 5 and detects an abnormal state when detecting an abnormality in at least one of the security states monitored by each sensor 3. Is output to the communication system switching unit 6 </ b> C of the communication interface unit 6.

  The power supply stop detection unit 9 monitors the power supply state from the normal power source 20 such as commercial AC power that constantly supplies power to the device 2 of the present invention, and detects the power supply stop state when the power supply stop detection from the normal power source 20 is detected. A power failure detection signal E1 for informing outside is generated and output to the communication system switching unit 6C of the communication interface unit 6. The device 2 of the present invention is constructed based on general computer hardware as will be described later, and AC power supplied from a normal power source 20 is once converted into AC / DC by a power source unit 13 including an AC / DC converter. DC power is supplied to each part. In the present embodiment, an emergency power supply device 12 as a rechargeable DC power source such as a battery is connected to the power supply unit 13. When the power supply from the normal power supply 20 to the power supply unit 13 is stopped, the supply of DC power from the AC / DC converter is also stopped, the output voltage is lowered, and the power supply from the emergency power supply device 12 to the power supply unit 13 is automatically supplied. It is configured to start. The power supply stop detection unit 9 can detect a power supply stop from the normal power supply 20 by monitoring the output voltage of the AC / DC converter, for example.

  When the power supply from the normal power supply 20 is stopped, the power failure cause analysis unit 10 determines whether or not the cause of the power supply stop is due to the individual artificial interruption of the power supply system from the normal power supply 20 to the device 2 of the present invention. When the cause of the power supply stop is individual artificial, an artificial power failure detection signal E2 is generated. The power supply system from the normal power source 20 to the device 2 of the present invention has a power distribution line from the outdoor trunk line of the normal power source 20 to the wattmeter (not shown) of each house, and a power distribution system including a safety device 21 such as a breaker from the wattmeter. It consists of indoor wiring to the panel, indoor wiring from the safety device 21 to the device 2 of the present invention, and the like. Even if any part of the power supply system is artificially disconnected, the power supply to the device 2 of the present invention is stopped. Further, even when a current exceeding the allowable current capacity of the safety device 21 flows, the safety device 21 is activated to open the circuit, and the power supply to the device 2 of the present invention is stopped. Furthermore, when the outdoor trunk line is in a power failure state, the power supply to the device 2 of the present invention is naturally stopped. Therefore, even if the power supply is stopped, the causes can be roughly classified into three types, so that the power failure cause analysis unit 10 can distinguish and recognize these power failure causes. And a current amount storage unit 16.

  The planned power outage storage unit 15 accepts access from the user terminal 14 via the user interface unit 7 and the computer network 4, and inputs a scheduled power outage scheduled time of planned power outage in the WEB format for the user terminal 14. It is configured to send data. When the user terminal 14 receives the input screen data, the user terminal 14 displays a predetermined input screen on the display screen of the user terminal 14, inputs a scheduled power outage scheduled time from the input screen, and stores the planned power outage. To the unit 15. The planned power outage storage unit 15 stores the scheduled power outage scheduled time of the planned power outage in a predetermined storage area of a storage device (not shown) built in the device 2 of the present invention. When the power supply from the normal power supply 20 is stopped, the power failure cause analysis unit 10 compares the actual power failure time with the scheduled power failure time stored in the storage device, and the actual power failure time and the scheduled power failure time are predetermined. If they match within the error range, it is determined that the cause of the power supply stop is due to a planned power failure, and the artificial power failure detection signal E2 is not transmitted.

  The current amount storage unit 16 receives the measured current value of an ammeter 22 such as a current transformer provided in the indoor wiring portion from the safety device 21 of the power supply system from the normal power supply 20 to the present invention device 2 to the present invention device 2. Then, sampling is performed at a constant time interval, and the past fixed time is sequentially stored in a predetermined storage area of a storage device (not shown) built in the inventive device 2. When power supply from the normal power supply 20 is stopped, the power failure cause analysis unit 10 compares the measured current value of the ammeter 22 sequentially stored in the storage device with the allowable current capacity of the safety device 21, for example, When the measured current value within a certain time immediately before the power failure time is within a certain range with respect to the allowable current capacity, it is determined that the cause of the power supply stop is due to the operation of the safety device 21, and the artificial power failure detection signal E2 Do not send.

  When the power supply from the normal power supply 20 is stopped, the power failure cause analysis unit 10 compares the actual power failure time with the scheduled power failure time stored in the storage device, and the actual power failure time and the scheduled power failure time are predetermined. If the measured current value within a certain time immediately before the actual power failure time is not within the certain range with respect to the allowable current capacity, the cause of the power supply stop is If it is neither a planned power outage nor an operation of the safety device 21, it is determined that the power supply system from the normal power supply 20 to the power supply system 2 of the present invention 2 is due to an individual human power interruption action, and a human power outage detection signal Send E2.

  The line disconnection detection unit 11 detects disconnection of the wired communication line 40. Specifically, the line break detection unit 11 periodically communicates with the external reception device 30 via a wired communication line, and disconnects the wired communication line 40 based on a response signal from the external reception device 30. Detect. That is, when no response signal is received from the external reception device 30 or when a signal that is not a response signal that is normally received is received, it is determined that the wired communication line 40 is disconnected, and the disconnection state is detected. When detecting the disconnection of the wired communication line 40, the line disconnection detection unit 11 outputs a signal for internally reporting the disconnection detection state to the communication system switching unit 6 </ b> C of the communication interface unit 6. When receiving the signal, the communication system switching unit 6C switches from the normally selected wired communication interface unit 6A to the wireless communication interface unit 6B.

  The line disconnection detection unit 11 further includes a planned reception stop storage unit 17 and a disconnection detection signal generation unit 18. The planned reception stop storage unit 17 receives an input of the reception stop time from the external reception device 30 when a planned functional stop of the external reception device 30 is scheduled, and the storage device ( It is stored in a predetermined storage area (not shown). When the disconnection detection signal generator 18 receives no response signal from the external receiving device 30 or receives a signal that is not a response signal that is normally received, the disconnection detection signal generator 18 determines that the wired communication line 40 is disconnected, and the disconnection state. Is detected, and a disconnection detection signal F1 for informing the disconnection state to the outside is generated and output to the communication system switching unit 6C of the communication interface unit 6. The disconnection detection signal generation unit 18 determines the plan of the external reception device 30 when the detection time of the disconnection state matches the reception stop time stored in the planned reception stop storage unit 17 within a predetermined error range. As a general function stop, the disconnection detection signal F1 is not transmitted. Therefore, the communication system switching unit 6C does not need to switch from the normally selected wired communication interface unit 6A to the wireless communication interface unit 6B, but may perform the switching process just in case.

  The abnormal state detection unit 8, the power supply stop detection unit 9, the power failure cause analysis unit 10, and the line disconnection detection unit 11 of the device 2 of the present invention are configured by a computer and software executed on its hardware. The sensor interface unit 5, the communication interface unit 6, and the user interface unit 7 include hardware that physically executes each data communication and communication software that executes each communication process in software. Is done. Note that the sensor interface unit 5 does not necessarily have to include communication software if data can be transmitted and received by communication at a physical level.

  Next, an example of a processing procedure in which the device 2 of the present invention detects a power supply stoppage from the normal power supply 20 and transmits a power failure detection signal E1 to the outside will be described with reference to a flowchart shown in FIG.

  When the device 2 of the present invention starts operating, the power supply stop detection unit 9 monitors the power supply state from the normal power supply 20 (step # 11). As described above, the power supply state is monitored by monitoring the output voltage of the AC / DC converter of the power supply unit 13, for example. At the same time, the current amount storage unit 16 of the power failure cause analysis unit 10 sequentially stores the measured current value of the ammeter 22. In addition, when the user of the security system 1 accesses the planned power outage storage unit 15 from the user terminal 14 via the user interface unit 7 and the network 4, and the power outage of the normal power supply 20 is scheduled, the power outage scheduled time Is input in advance.

  When the power supply from the normal power supply 20 is stopped, the power supply to the device 2 of the present invention is automatically switched from the normal power supply 20 to the emergency power supply apparatus 8 by the power supply unit 8 (step # 12). At the same time, the power supply stop detection unit 9 detects a power supply stop from the normal power supply 20 and generates a power failure detection signal E1 (step # 13). Further, the power failure cause analysis unit 10 is based on the scheduled power failure time stored by the planned power failure storage unit 15 (including a case where it is not stored) and the measured current value of the ammeter 22 sequentially stored by the current amount storage unit 16. It is determined whether or not the cause of the power supply stop is due to individual artificial interruption of the power supply system from the normal power supply 20 to the present invention device 2 (step # 14). Power failure detection signal E2 is generated (step # 15). When the artificial power failure detection signal E <b> 2 is generated, the communication interface unit 6 transmits the artificial power failure detection signal E <b> 2 including the power failure detection signal E <b> 1 to the server device 30 of the security company that manages the security system 1 and the security system 1. Are transmitted to both the external receiving devices 30 and 31 of the user terminal 31 of the user using the wired communication line 40 or the wireless communication line 41 effective at that time, and an alarm sound is also generated (step #). 16). In addition, when the artificial power failure detection signal E2 is not generated, the communication interface unit 6 distinguishes the power failure detection signal E1 from the artificial power failure detection signal E2, and the user terminal 31 (external reception) of the user of the security system 1 Only to the device 31), transmission is performed using the wired communication line 40 or the wireless communication line 41 that is valid at that time (step # 17).

  Although not shown in FIG. 2, in step # 11, the security state monitored by each sensor 3 based on the status signal S received from each sensor 3 by the abnormal state detection unit 8 is also simultaneously performed. Therefore, when the abnormal state detection unit 8 detects an abnormality simultaneously with or before or after the detection of the power supply stop by the power supply stop detection unit 9, an abnormal state detection signal D is generated. Regardless of whether or not the artificial power failure detection signal E2 is generated, the abnormal state detection signal D is separately sent to both the server device 30 of the security company that manages the security system 1 and the user terminal 31 of the user of the security system 1. It transmits to the receivers 30 and 31 using the wired communication line 40 or the wireless communication line 41 effective at that time, and generates a predetermined alarm sound.

  Next, an example of a processing procedure in which the device 2 of the present invention detects disconnection of the wired communication line 40, switches the communication line to be used from the wired communication line 40 to the wireless communication line 41, and transmits the disconnection detection signal F1 to the outside. This will be described with reference to the flowchart shown in FIG.

  When the device 2 of the present invention starts operation, the line disconnection detection unit 11 monitors the communication state between the device 2 of the present invention that passes through the wired communication line 40 and the server device 30 of the security company that manages the security system 1 (step) # 21). Specifically, the line disconnection detection unit 11 periodically communicates with the server device 30 (external reception device 30) via a wired communication line, and a wired communication line based on a response signal from the server device 30. The presence or absence of 40 disconnection is determined. In addition, when a temporary stoppage of service due to maintenance of the server device 30 is scheduled, the security company, together with a response signal for the access from the server device 30 to the periodic server device 30, a line disconnection detection unit 11, the data transmission at the reception stop time due to the service stop is performed. The planned reception stop storage unit 17 inputs the reception stop time in advance.

  When the line disconnection detection unit 11 detects a disconnection state of the wired communication line 40, the communication system switching unit 6C switches from the normally selected wired communication interface unit 6A to the wireless communication interface unit 6B. (Step # 22). At the same time, the disconnection of the wired communication line 40 is caused by the planned function of the external receiving device 30 based on the reception stop time (including the case where it is not stored) stored in the reception stop storage unit 17 by the line disconnection detection unit 11. It is determined whether it has been erroneously detected due to a stop (service stop) (step # 23), and when it is not caused by a planned function stop (when it is not a false detection), the disconnection detection signal generator 18 detects the disconnection detection signal F1. Is generated (step # 24). When the disconnection detection signal F1 is generated, the communication interface unit 6 receives the disconnection detection signal F1 from both the server device 30 of the security company that manages the security system 1 and the user terminal 31 of the user of the security system 1. While transmitting to the apparatuses 30 and 31 using the radio | wireless communication line 41, a warning sound is also generated together (step # 25).

  When the determination that the wired communication line 40 is disconnected is due to a planned function stop (in the case of erroneous detection), the reception stop period (reception stop time and restart) stored in the reception stop storage unit 17 During the time), periodic communication with the server device 30 via the wired communication line 40 is temporarily interrupted (step # 26). After the suspension period ends, the communication line is switched to the wired communication line 40 (step # 27), and the process returns to step # 21.

  Although not shown in FIG. 3, in step # 21, the security state monitored by each sensor 3 based on the state signal S received from each sensor 3 by the abnormal state detection unit 8 is also simultaneously performed. Therefore, when the abnormal state detection unit 8 detects an abnormality at the same time as or before or after the detection of the disconnection of the wired communication line 40 by the line disconnection detection unit 11, an abnormal state detection signal D is generated. The unit 6 separately outputs the abnormal state detection signal D to both the server device 30 of the security company that manages the security system 1 and the user terminal 31 of the user of the security system 1 regardless of whether or not the disconnection detection signal F1 is generated. To the external receivers 30 and 31 using the wired communication line 40 or the wireless communication line 41 effective at that time, and generates a predetermined alarm sound.

Second Embodiment
Next, a second embodiment of the device 2 of the present invention will be described. The configuration of the device 2 of the present invention is the same as that of the first embodiment. The difference from the first embodiment is the function and operation of the power failure cause analysis unit 10 and the line disconnection detection unit 11. Hereinafter, the different functions and operations will be described with reference to respective processing procedures of the power failure cause analysis unit 10 and the line disconnection detection unit 11.

  First, an example of a processing procedure in which the inventive device 2 of the second embodiment detects a power supply stop from the normal power supply 20 and transmits a power failure detection signal E1 to the outside will be described with reference to a flowchart shown in FIG.

  When the device 2 of the present invention starts operation, the power supply stop detection unit 9 monitors the power supply state from the normal power supply 20 (step # 31). As described above, the power supply state is monitored by monitoring the output voltage of the AC / DC converter of the power supply unit 13, for example. At the same time, the current amount storage unit 16 of the power failure cause analysis unit 10 sequentially stores the measured current value of the ammeter 22. In addition, when the user of the security system 1 accesses the planned power outage storage unit 15 from the user terminal 14 via the user interface unit 7 and the network 4, and the power outage of the normal power supply 20 is scheduled, the power outage scheduled time Is input in advance.

  When the power supply from the normal power supply 20 is stopped, the power supply to the device 2 of the present invention is automatically switched from the normal power supply 20 to the emergency power supply apparatus 8 by the power supply unit 8 (step # 32). The communication system switching unit 6C switches from the normally selected wired communication interface unit 6A to the wireless communication interface unit 6B. (Step # 33). At the same time, the power supply stop detection unit 9 detects a power supply stop from the normal power supply 20 and generates a power failure detection signal E1 (step # 34).

  The power failure cause analysis unit 10 transmits a power failure detection signal E1 to the wireless master device 43 of the wireless communication line 41 (an example of a repeater of the wireless communication line 41) (step # 35). Here, assuming that there are a plurality of users of the same system as the security system 1 within the communication range of the same wireless master unit 43, in the case of a power failure of the normal power supply 20 itself, the device 2 of the present invention of another user. Similarly, the power supply stoppage is detected and the power failure detection signal E1 is transmitted almost simultaneously to the wireless master device 43, so that the reception state of the power failure detection signals E1 from the plurality of the present invention devices 2 is shown. If the second power failure detection signal E3 is received from the wireless master device 43 (step # 36) and the power supply is not limited to the normal power supply 20 itself but the power supply is limited to a specific user, the second power failure detection signal E3 is received. Do not receive.

  The power failure cause analysis unit 10 has received the second power failure detection signal E3, the scheduled power failure time stored in the planned power failure storage unit 15 (including cases where it is not stored), and the current amount storage unit 16 sequentially stored. Based on the measured current value of the ammeter 22, it is determined whether or not the cause of the power supply stop is due to individual artificial interruption of the power supply system from the normal power supply 20 to the present invention device 2 (step # 37). If the cause of the error is individual artificial, an artificial power failure detection signal E2 is generated (step # 38). When the human power failure detection signal E <b> 2 is generated, the communication interface unit 6 uses the human power failure detection signal E <b> 2 as the user terminal of the security system server device 30 and the security system 1 user who manages the security system 1. It transmits to both external receivers 30 and 31 using the wired communication line 40 or the wireless communication line 41 effective at that time, and also generates an alarm sound (step # 39). In addition, when the artificial power failure detection signal E2 is not generated, the communication interface unit 6 distinguishes the power failure detection signal E1 from the artificial power failure detection signal E2, and the user terminal 31 (external reception) of the user of the security system 1 Only to the device 31), transmission is performed using the wired communication line 40 or the wireless communication line 41 that is valid at that time (step # 40).

  In the second embodiment, the power failure cause analysis unit 10 may not necessarily include the planned power failure storage unit 15. Depending on whether or not the second power failure detection signal E3 is received, it is possible to simultaneously confirm that the normal power source 20 itself is a planned power failure. Since the second power failure detection signal E3 can confirm a sudden power failure of the normal power source 20 itself in addition to the planned power failure, more advanced analysis of the cause of power supply stop is possible compared to the first embodiment. Become.

  Next, the present invention device 2 of the second embodiment detects disconnection of the wired communication line 40, switches the communication line to be used from the wired communication line 40 to the wireless communication line 41, and transmits the disconnection detection signal F1 to the outside. An example of the procedure will be described with reference to the flowchart shown in FIG.

  When the device 2 of the present invention starts operation, the line disconnection detection unit 11 monitors the communication state between the device 2 of the present invention that passes through the wired communication line 40 and the server device 30 of the security company that manages the security system 1 (step) # 41). Specifically, the line disconnection detection unit 11 periodically communicates with the server device 30 (external reception device 30) via a wired communication line, and a wired communication line based on a response signal from the server device 30. The presence or absence of 40 disconnection is determined. In addition, when a temporary stop of service due to maintenance of the server device 30 is scheduled, the security company, along with a response signal for the access from the server device 30 to the periodic server device 30, a line disconnection detection unit 11, the data transmission at the reception stop time due to the service stop is performed. The planned reception stop storage unit 17 inputs the reception stop time in advance.

  When the line disconnection detection unit 11 detects a disconnection state of the wired communication line 40, the communication system switching unit 6C switches from the normally selected wired communication interface unit 6A to the wireless communication interface unit 6B. (Step # 42). The disconnection detection signal generation unit 18 of the line disconnection detection unit 11 generates a disconnection detection signal F1 (step # 43), and the wireless master unit 43 of the wireless communication line 41 (an example of a repeater of the wireless communication line 41). Then, the disconnection detection signal F1 is transmitted (step # 44). Here, assuming that there are a plurality of users of the same system as the security system 1 within the communication range of the same wireless master unit 43, the wired communication line 40 is disconnected simultaneously and frequently in common with the plurality of security systems. In the state, the disconnection of the wired communication line 40 is similarly detected in the present invention device 2 of another user, and the disconnection detection signal F1 is transmitted to the wireless master unit 43 almost simultaneously. Therefore, the second disconnection detection signal F2 indicating the reception state of the disconnection detection signals F1 from the plurality of devices 2 of the present invention is received from the wireless master device 43 (step # 45). When the disconnection is limited to a specific user and not the simultaneous frequent disconnection of the wired communication line 40, the device 2 of the present invention does not receive the second disconnection detection signal F2.

  The line disconnection detection unit 11 detects whether the wired communication line 40 is disconnected based on whether or not the second disconnection detection signal F2 is received and the reception stop time stored in the reception stop storage unit 17 (including the case where it is not stored). It is determined whether it is an individual artificial disconnection that has occurred in a limited manner in the user of the present invention device 2 (step # 46). When the disconnection of the wired communication line 40 is determined to be an individual artificial disconnection, the communication interface unit 6 uses the disconnection detection signal F1 and the security system server device 30 that manages the security system 1 and the use of the security system 1. The wireless communication line 41 is used for transmission to both external receivers 30 and 31 of the user's user terminal 31, and an alarm sound is also generated (step # 47). On the other hand, when the disconnection of the wired communication line 40 is determined to be an individual artificial disconnection, the communication interface unit 6 sends the disconnection detection signal F1 to the user terminal 31 (external reception device 31) of the user of the security system 1. (Step # 48).

  In the second embodiment, the line disconnection detection unit 11 may not necessarily include the reception stop storage unit 17. Whether it is possible to simultaneously confirm that the disconnection of the wired communication line 40 has been erroneously detected due to a planned function stop (service stop) of the external receiving device 30 depending on whether or not the second disconnection detection signal F2 is received. is there. Since the second disconnection detection signal F2 can be confirmed in addition to the planned function stop of the external receiving device 30 in the case of simultaneous disconnection detection due to a sudden stop of the function or the like, the second embodiment is used in the first embodiment. In comparison, the disconnection of the wired communication line 40 can be detected more accurately.

  In the second embodiment as well, the operation of the abnormal state detection unit 8 is the same as that in the first embodiment, and a duplicate description is omitted.

  Hereinafter, another embodiment will be described.

Although it is configured to determine whether or not the power supply stop or the disconnection of the wired communication line 40 is individual artificial, only one of the power failure cause analysis unit 10 and the line disconnection detection unit 11 performs the second implementation. The configuration may be in the form. In that case, the other should just employ | adopt the structure of the said 1st Embodiment.

It doesn't matter.

  Further, for example, when a planned power outage is stored in the planned power outage storage unit 15 is searched every day at a predetermined time (for example, 1 am), for example, and a planned power outage is scheduled on that day The present invention apparatus 2 may be provided with a function of transmitting in advance information for notifying the occurrence of the planned power outage to the external receiving devices 30 and 31 a predetermined time before the scheduled power outage time.

  <3> In the first embodiment described above, even when the disconnection detection unit 11 detects that the disconnection of the wired communication line 40 is erroneously detected due to a planned function stop of the external receiving device 30, the reception stop time In preparation for a case where an error occurs in the determination itself due to a transmission error or change, the disconnection detection signal F1 is generated, and the communication interface unit 6 transmits the disconnection detection signal F1 together with the determination result to the external receivers 30 and 31. You may make it.

  <4> In the second embodiment, the communication interface unit 6 outputs the disconnection detection signal F1 including the determination result to the outside regardless of whether or not the disconnection of the wired communication line 40 is determined as an individual artificial disconnection. You may make it transmit to the receivers 30 and 31.

However, the emergency power supply device 12 has stopped supplying power from the normal power supply 20 to the power supply unit 13. Since it is sufficient that the electric capacity is sufficient to perform the above-described notification or the like in a certain period after the power supply is stopped, it is not always necessary to use a rechargeable power supply or an unnecessarily large capacity power supply. For example, the person in charge of the security company that manages the security system 1 may be replaced when dispatched by the notification. When a rechargeable DC power supply is used, charging and discharging may be repeated periodically according to the type and structure of the emergency power supply device 12 in order to maintain a predetermined performance and life.
