The present invention relates to a disaster prevention monitoring system for monitoring an abnormality such as a fire by connecting a fire sensor having a transmission function to a sensor line drawn from a receiver.

  Conventional disaster prevention monitoring systems have receivers installed at disaster prevention centers, and fire detectors, transmitters, local sound equipment, and smoke control equipment are installed on the terminal side, which is the alert area, and each is connected to the receiver. A system is configured by connecting to a transmission line.

  In such a disaster prevention monitoring system, when a fire detector is activated and an operation indication is made at the receiver, the administrator of the disaster prevention monitoring system goes to the operation area displayed on the receiver of the disaster prevention center and Check the situation, return to the disaster prevention center after confirmation, or contact another administrator and perform a fire confirmation operation with the receiver to sound the district acoustic alarm, evacuation guidance by emergency broadcast, report to the fire engine, etc. It is the operation to take appropriate measures.

On the other hand, in facilities such as buildings where disaster prevention monitoring systems are installed, other facilities for monitoring and control, such as security systems, air conditioning systems, and entrance / exit management systems, are installed at the same time. The system is constructed by laying lines (wiring).

There is a risk that the transmission speed of the fire alarm transmission line necessary for monitoring cannot be secured.

  FIG. 1 is an explanatory view showing an embodiment of a disaster prevention monitoring system according to the present invention. In FIG. 1, a fire alarm transmission line 12 is drawn out from a receiver 10 installed in a disaster prevention center or the like toward a warning area in a building. An area controller 14 is arranged separately for areas A and B. The fire alarm transmission line 12 is drawn from the area controller 14 in the same manner as the receiver 10, and a fire detector 16 having a transmission function installed in each of the areas A and B is connected.

  Each area controller 14 has a unique controller address set in advance. The controller address is, for example, an 8-bit address. Therefore, up to 255 addresses can be connected per line of the fire alarm transmission line 12, but the number of areas does not increase so much even in a large-scale facility. There is enough room.

  Each of the fire detectors 16 connected to the fire alarm line 12 from the area controller 14 has a unique detector address set in advance. The sensor address is, for example, an 8-bit address. Therefore, up to 255 addresses per fire alarm transmission line 12 can be connected. However, in consideration of an increase in traffic due to monitoring terminals of other facilities, for example, the number of sensor connections per line is limited to 64, which is 1/4 of the maximum address.

  Transmission of the fire alarm transmission line 12 between the receiver 10 and the area controller 14 and between the area controller 14 and the fire detector 16 is performed according to a fire alarm line transmission protocol. The fire alarm line transmission protocol for 1-to-n communication follows, for example, the following procedure.

  (1) A plurality of lower-level devices are sequentially specified from the higher-level device and a polling signal is periodically transmitted.

  (2) When a lower level device receives a polling signal that matches its own address, if there is a transmission request, an interrupt signal is transmitted to the higher level device.

  (3) When the host device receives the interrupt signal, the group search command signal sequentially specifying the group address is sequentially transmitted to the lower device to identify the group of the lower device having the interrupt response signal.

  (4) The in-group search command signal is transmitted by sequentially designating addresses belonging to the group of lower-level devices identified from the higher-level device.

  (5) When the in-group search command signal matching the self address is received in the lower level device, a signal based on the transmission request is transmitted to the higher level device.

  The transmission process according to the fire report line transmission protocol will be specifically described for the area controller 14 and the fire detector 16 as follows.

  During normal monitoring, the area controller 14 transmits a polling command for normal monitoring in which detector addresses are sequentially specified. When the fire detector 16 receives a polling command that matches its own set address, Perform normal monitoring response. For this reason, in the area controller 14, when there is a fire sensor 16 that has not responded to the polling command, a failure of the fire sensor is detected.

  When the fire detector 16 receives a batch AD conversion command that is repeatedly output at every polling command transmission period for all the sensor addresses of the area controller 14, an analog such as smoke concentration and temperature in the built-in fire detection mechanism is received. The detection data is sampled, compared with a predetermined fire level, and a fire is detected when the fire level is exceeded.

  When the fire detector 16 determines a fire from the sampling result based on the batch AD conversion command, an interrupt signal is transmitted to the area controller 14 at the timing of the subsequent polling command designating its own detector address. The interrupt signal is a signal which is not normally used so that the response bit is all 1.

  When the area controller 14 receives the interrupt signal from the fire detector 16 side, it issues a group search command, receives an interrupt response from the group including the fire detector that has detected the fire, determines the group, and then continues. The individual fire detectors included in the identified group are polled in sequence with addresses, and the fire response is received to recognize the sensor address of the fire detector 16 that detected the fire, and fire detection. Fire monitoring information including area information converted from the information and the sensor address is generated, and the generated fire monitoring information is transmitted to the receiver 10 according to the same fire report line transmission protocol to cause a fire alarm.

  For the 64 fire detectors 16 connected to the fire alarm transmission line 12 from the area controller 14, for example, a group address is set for every 8 units, and a fire is detected in response to a group search command from the area controller 14. An interrupt response is made from the group including the detecting sensor so that the group including the fire sensor 16 detecting the fire can be identified.

  On the other hand, the transmission process by the fire alarm line transmission protocol will be specifically described for the transmission between the receiver 10 and the area controller 14 as follows.

  During normal monitoring, the receiver 10 transmits a polling command for normal monitoring in which controller addresses 14 are sequentially specified. When the area controller 14 receives a polling command that matches its own set address, the receiver 10 is normal. Perform monitoring response. Therefore, in the receiver 10, when there is an area controller 14 that has not responded to the polling command, a failure of the area controller 14 is detected.

  When a transmission request is generated by generating fire detection information in the area controller 14, an interrupt signal is transmitted to the receiver 10 at the timing of a subsequent polling command designating its own controller address.

  When the receiver 10 receives the interrupt signal from the area controller 14 side, the receiver 10 issues a group search command, receives an interrupt response from the group including the area controller in which the transmission request is generated, determines the group, and then continues. Then, each area controller included in the determined group is sequentially polled by designating an address, receives the fire monitoring information transmitted from the area controller 14 when the addresses match, and detects the fire detection information included in the fire monitoring information. Fire alarm processing is executed based on the area information.

  In addition to the disaster prevention monitoring system in which the receiver 10, the area controller 14, and the fire detector 16 having a transmission function are connected via the fire report transmission line 12, in the present embodiment, in the same facility, security monitoring is performed. Other equipment such as a system, an energy saving system, and an entrance / exit management system are installed at the same time, and other equipment monitoring devices 20, 22, and 24 are installed corresponding to the other equipment.

  Further, in the warning area for each of the areas A and B where the fire detector 16 is installed, an emergency push button device 26, a person counter 28, and a power sensor 30 are used as monitoring terminals corresponding to the other equipment monitoring devices 20, 22, and 24. A CO sensor 32, a temperature sensor 34, a card reader 36, and the like are installed.

  When these monitoring terminals detect a predetermined event, the monitoring terminal transmits an upstream event signal including a vendor identifier serving as a destination identifier for specifying other equipment of the transmission destination and detection information to the fire detector 16. The monitoring terminal may be provided with a display function and a control function. In this case, the monitoring terminal receives a control event signal from the fire detector 16 and executes the process. In addition to the monitoring terminal, a control terminal dedicated to control may be provided.

  The event signal transmitted from the monitoring terminal to the other equipment monitoring devices 20, 22, 24 is hereinafter referred to as an upstream event message (upstream event signal). On the other hand, the event signal sent from the other equipment monitoring devices 20, 22, 24 to the monitoring terminal is hereinafter referred to as a downlink event message (downlink event signal).

  Each of the emergency push button device 26, the person counter 28, the power sensor 30, the CO sensor 32, the temperature sensor 34, and the card reader 36 as a monitoring terminal is connected to the fire detector 16 through a wireless line. For example, when an event due to a push button operation occurs in the emergency push button device 26, an up event message having a vendor identifier (vendor ID) indicating a transmission destination (destination) and event information (detection information) indicating on / off of the emergency push button is generated. Then, it is wirelessly transmitted and received by the fire detector 16 existing in the communicable area.

  The fire detector 16 that has received the up event message from the emergency push button device 26 converts the up event message into an up event message including the sensor address in the up event message, and transmits it to the area controller 14 in accordance with the fire report line transmission protocol.

  That is, when the fire detector 16 receives an up event message from the emergency push button device 26, an interrupt signal is transmitted in the same manner as when a fire is detected in response to reception of a polling command designating a sensor address from the area controller 14.

  When the area controller 14 receives the interrupt signal from the fire detector 16, the area controller 14 transmits a group search command and receives an interrupt response from the fire sensor that has received the upstream event message, thereby specifying the group address.

  When the group address is specified, polling is performed by sequentially designating the detector addresses of the eight fire detectors 16 included in the group. For this reason, the fire detector 16 receiving the upstream event message fires the upstream event message including the sensor address by determining the self-address by polling specifying the sensor address in the group from the receiver 10. Information is transmitted to the area controller 14 via the information transmission line 12.

  When the area controller 14 receives the upstream event message from the fire detector 16, the area controller 14 performs a calculation according to a predetermined algorithm based on the information received from itself and other monitoring terminals, and collects the collected monitoring information. An upstream event message is generated by adding the area information and time information created from the sensor address and the like, and transmitted to the receiver 10 according to the fire report line transmission protocol.

  Other equipment monitoring devices 20, 22, and 24 are connected to the receiver 10 via a general-purpose transmission line 18. As the general-purpose transmission line 18, a transmission line to which a transmission interface such as RS-232C or RS-485 is applied is used. Ethernet (R) or the like may be used.

  When the receiver 10 receives the upstream event message from the area controller 14, the receiver 10 transmits the upstream event message to, for example, the other equipment monitoring apparatus 20 that is a transmission destination specified by the vendor identifier included in the upstream event message.

  The other equipment monitoring device 20 decodes the upstream event message received from the receiver 10 and is generated in the area where the area controller 14 is installed based on the area information, time information, and aggregated monitoring information included therein. Processing such as display, control, processing, and storage corresponding to the monitoring information is performed.

  In addition, the other equipment monitoring devices 20, 22, and 24 can transmit a downlink event message for appropriate processing such as display and control to a monitoring terminal and a control terminal that are provided in correspondence with each other.

  For example, when it is desired to send information from the other equipment monitoring device 20 to the emergency pushbutton terminal device 26 for display, this display information is used as control information, and a down event message including area information indicating the installation location of the emergency pushbutton terminal device 26 is displayed. And transmitted to the receiver 10 via the general-purpose transmission line 18.

  When receiving the downlink event message, the receiver 10 identifies the corresponding controller address 14 from the area information, and transmits the downlink event message to the addressed area controller 14 at the polling timing of the area controller 14.

  When the area controller 14 receives the downlink event message, the area controller 14 extracts the control information included therein, analyzes the control information according to a predetermined algorithm, converts the control information into terminal control information necessary for processing of one or a plurality of control terminals, and converts the control information. A downstream event message is created by adding the sensor address converted from the area information to the terminal control information, and is transmitted to the corresponding one or more fire sensors 16 according to the fire report line transmission protocol.

  When the fire detector 16 receives the down event message, the fire detector 16 transmits the down event message as it is to the monitoring terminal or the control terminal. The monitoring terminal or the control terminal performs, for example, a display operation in the emergency push button device 26 based on the terminal control information included in the received downlink event message.

  FIG. 14 is a time chart showing transmission timings during normal monitoring in the area controller and the fire detector in the present embodiment. In FIG. 14, four fire detectors 16-1 to 16-4 are shown for the area controller 14, and addresses of the fire detectors 16-1 to 16-4 are addresses 1 to 4.

  After transmitting the batch AD conversion command 170, the area controller 14 transmits polling commands 172-1 to 172-255 in which addresses corresponding to the maximum number of detectors of 255 are sequentially specified at regular intervals, and then the batch AD conversion again. A conversion command 170 is transmitted.

  The fire detectors 16-1 to 16-4 that have received the batch AD conversion command 170 simultaneously perform sampling 174-1 to 174-4 of the fire detection information, compare the sampled data with the fire level, and detect the fire detection. Judgment is made.

  Responses 175-1 to 175-4 indicating normal monitoring operations are transmitted to the polling commands 172-1 to 172-4, respectively. If no response is obtained from the fire detector side, the area controller 14 treats the fire detector as a failure.

  FIG. 15 is a time chart showing the transmission timing when a fire occurs in this embodiment. In FIG. 15, if the fire detector 16-1 performs fire determination in the sampling 174-1 to 174-4 of the fire detectors 16-1 to 16-4 by the batch AD conversion command 170, for example, the following polling is performed.

  At this time, in response to the first polling command 182-1, the fire detector 16-1 detecting a fire makes a fire response 184. As a result, the area controller 14 recognizes that the fire detector 16-1 at the address 1 has detected the fire, converts the sensor address into area information, and includes the fire detection information and the area information by the fire monitoring calculation. An upstream event message is created and transmitted to the receiver 10 to display a fire alarm.

In response, the area controller 14 transmits a search command for group 1 in step S6. Here, if the fire detector that detected the fire belongs to group 2, the fire detector 16 becomes unresponsive at step S7 to the search command of group 1 at step S6.

  Subsequently, the area controller 14 transmits a search command for group 2 in step S8, and since the fire detector 16 that detects a fire belongs to group 2, it transmits an interrupt response in step S9. The area controller 14 that has received the interrupt response in step S9 designates the first sensor address in the group address in step S10, and transmits a first in-group search command.

  Here, if the area controller 14 is the second address in the group, no response is made in step S11. Next, the area controller 14 transmits the in-group second search command in step S12. On the other hand, the fire detector 16 determines its own address and transmits a fire response in step S13. In response to the fire response in step S13, the area controller 14 recognizes the sensor address that detected the fire in step S14.

  Subsequently, the same processing is performed for the third address to the seventh address in the group, but no response is made, a search command for the last address in the group is sent in step S15, and no response is made in step S16. A fire information transmission process is performed in which an upstream event message including fire monitoring information created by the fire monitoring calculation is transmitted to the receiver 10 according to a fire alarm line transmission algorithm.

  The receiver 10 receives the upstream event signal from the area controller 14 in step S18, and executes fire alarm processing based on the fire detection information and area information in step S19.

  The fire detector 16 receives the upstream event message 114-1 from the monitoring terminal 25 in step S23, and creates the upstream event message 114-2 shown in FIG. Subsequently, in step S24 of the fire detector 16 and step S25 of the area controller 14, an upstream message transmission process and an upstream message reception process are performed in accordance with the fire alarm line transmission algorithm. 114-2 is transmitted to the area controller 14.

  Subsequently, the fire detector 16 creates an upstream event message 114-2 that receives the upstream event message 114-1 from another monitoring terminal (not shown) and transmits it to the area controller 14 in step S26. By the process of S27 and step S28 in the area controller 14, the upstream message transmission process and the upstream message reception process according to the fire alarm line transmission algorithm are executed, and the upstream event message 114-2 is transmitted to the area controller 14.

In FIG. 18, when an event for transmitting control information to the monitoring terminal 25 in the other equipment monitoring device 20 occurs in step S41, the downlink event message 136-1 shown in FIG. 10A is created in step S42. It transmits to the receiver 10 by the downstream message transmission process of a general-purpose line.

  The receiver 10 receives the down event message 136-1 from the other equipment monitoring device 20 in step S 43, and creates a down event message 136-2 for the area controller 14 shown in FIG. In accordance with the fire alarm line transmission algorithm in accordance with the fire alarm line transmission algorithm, the downstream event telegram 136-2 is associated with the fire alarm line downlink telegram transmission process in the receiver 10 in step S44 and the fire alarm line downlink telegram reception process in step S45. Is transmitted to the area controller 14.

  In step S46, the area controller 14 calculates terminal control information for the control terminal existing in its own area based on the received control information 150 of the downlink event message 136-2, and the result is shown in FIG. A downlink event message 136-3 for transmission to the fire detector 16 is created, and the downlink message transmission process of the fire alarm line in step S47 and the linkage of the downlink message reception process of the fire alarm line in step S48 of the fire detector 16 are linked. Thus, the downstream event message 136-3 is transmitted from the area controller 14 to the fire detector 16 by the fire report line transmission algorithm.

  In step S49, the fire detector 16 creates the down event message 136-4 shown in FIG. 10D having the control information 151 included in the down event message 136-3 received from the area controller 14, and sends it to the monitoring terminal 25. A downlink message is transmitted wirelessly. The monitoring terminal 25 decodes the downstream event message 136-4 received from the fire detector 16 in step S50, and executes processing based on the terminal control information 151.

  On the other hand, in the area controller 14, in the calculation of the terminal control information in step S46, the terminal control information for not only the monitoring terminal 25 but also other monitoring terminals and control terminals is calculated at the same time. For the terminal control information, the downlink event message 136-4 including the terminal control information is wirelessly transmitted to the corresponding monitoring terminal or control terminal by executing the downlink message transmission process of the fire alarm transmission line in each of steps S51 and S52. Then, the process based on the terminal control information is executed.
