  However, in such a conventional disaster prevention facility, in a transmission system that transmits a response message from a terminal device in response to transmission of a call message from a control panel, the addresses of a plurality of terminal devices from the control panel are, for example, ascending order. There is a problem that the time it takes to receive a response message from the terminal device increases as the address of the terminal device increases, while the call message is transmitted while being repeatedly specified in order.

  For example, in a disaster prevention monitoring facility that monitors a fire, after sending a message containing a batch AD conversion command every 1 minute and detecting sensor data with all fire detectors, for example, including the maximum number of addresses including the receiver 256 addresses, the call message is transmitted while sequentially specifying the sensor address from 1 to 255, and it takes less than 1 minute until the sensor data is received by the response message from the fire detector at the last address 255. There is a problem that takes time.

  The time delay until sensor data reception due to such a call message does not matter so much in the normal monitoring state where a fire does not occur, but after detecting sensor data due to fire with a fire sensor with a large address, the receiver There is a problem that the delay time until the sensor data is received becomes large and the real-time property of the sensor data is deteriorated due to the fire.

  The present invention provides a transmission system for a disaster prevention facility that can reduce the delay in receiving a response of important information by changing the order of calling terminal devices by a call message from a control panel according to the state of the terminal device. For the purpose.

Addresses are set in descending order of weight values, and a call message is transmitted to the terminal device.

(Set the weight value according to the date of manufacture of the terminal device)

Send a message.

(Control of the number of terminal calls by weight value)
The control unit changes the number of times the call message is transmitted to the terminal device according to the weight value.

(Basic effects of transmission system)
The present invention draws out a transmission line whose maximum address number is set to a predetermined value from the control panel, connects a number of terminal devices set with unique addresses to the transmission line, and sends a call message specifying an address from the control panel. In a disaster prevention equipment transmission system that sends and sends a response message from a terminal device whose self-address matches the address of the calling message, the address is set on the control panel in the order according to the state of the terminal device. Since the control unit for transmitting the call message is provided, the address is specified in the order determined according to the state of the terminal device, and the call message is transmitted. When the response message is sent to the control panel, the delay time of the response message can be shortened according to the status of the terminal device. Te address order is changed, it is possible to dynamically reduce the delay time of the response message from the terminal device in a specific state.

(Effects of setting weight values according to the terminal device status)
In addition, the control unit sets the weight value according to the state of the terminal device, sets the address in the order based on the weight value, and transmits the call message to the terminal device. By sending a call message specifying addresses in the order determined by the weight value, the delay time of the response message can be shortened by the weight value according to the state of the terminal device, and when the state of the terminal device changes The address order is changed by the change of the weight value according to this, and the delay time of the response message from the terminal device in a specific state can be dynamically shortened.

(Effects of weight value setting according to connection / disconnection of terminal equipment)
The control unit sets a predetermined high weight value for a terminal device connected to the transmission line, sets a predetermined low weight value for a terminal device not connected to the transmission line, sets addresses in descending order of the weight value, and sets the terminal Since the call message is sent to the device, for example, when data detected by the terminal device is sent to the control panel by a response message to the call message at a fixed period, the call message is sent from the terminal device connected to the transmission line. Therefore, it is possible to improve the real time performance by shortening the time delay from the detection of data by the terminal device to the reception by the control panel.

(Effects of setting weight values according to the importance of detection information by terminal equipment)
In addition, the control unit sets a predetermined weight value that increases as the importance of the detection information detected by the terminal device increases, sets the address in order of increasing weight value, and transmits a call message to the terminal device. Specifically, since the predetermined weight value that increases with the importance of the control load controlled by the terminal device is set, the address is set in the descending order of the weight value, and the call message is transmitted to the terminal device. For example, when data detected by a terminal device is sent to the control panel by a response message to the calling message at a certain period, the terminal device with the higher importance of the detection information has a longer time delay from detection of the data to reception by the control panel. It can be shortened to improve real-time performance.

(Effects of setting weight values according to the fire risk of terminal equipment)
In addition, the control unit sets a predetermined weight value that increases as the fire risk level of the section that detects a fire at the terminal device increases, sets addresses in descending order of the weight value, and transmits a call message to the terminal device. For example, the control unit sets a predetermined weight value that becomes higher as the smoke concentration or temperature detected by the terminal device is higher, sets addresses in descending order of the weight value, and transmits a call message to the terminal device. Therefore, a more reliable determination can be made.

  For example, when sensor data such as temperature or smoke concentration detected by the terminal device is sent to the control panel by a response message to the calling message at a certain period, the higher the smoke concentration or temperature, the higher the risk of fire, the more the terminal device The delay time from the detection of sensor data to the reception of sensor data by the control panel can be shortened, and the sensor data of terminal devices with high risk of fire can be monitored in near real time, resulting in higher reliability Judgment is possible.

(Effects of setting weight values according to the terminal device history)
In addition, the control unit sets a predetermined weight value that increases as the number of fire alarms detected by the terminal device increases, the terminal device non-fire alarms increase, or the terminal device failure occurrences increase. Then, the address is set in descending order of the weight value and the call message is transmitted to the terminal device. For example, sensor data such as temperature or smoke concentration detected by the terminal device at a constant cycle is transmitted by a response message to the call message. Terminal devices with more fire alarms, the delay time from sensor data detection by the terminal device to sensor data reception by the control panel can be shortened. Sensor data can be monitored almost in real time.

  Also, by setting a predetermined weight value that increases as the number of non-fire notifications for terminal devices increases, the terminal device with the higher number of non-fire notifications detects failure data at the terminal device and It is possible to improve the real-time nature of fault monitoring by shortening the time delay until reception.

  Furthermore, by setting a predetermined weight value that increases as the number of failure occurrences of the terminal device increases, for example, when failure data detected by the terminal device is sent to the control panel by a response message to the calling message at a certain period, the number of failure occurrences A terminal device having a larger number of terminals can improve the real-time property by reducing the time delay from the detection of the failure data by the terminal device to the reception by the control panel.

(Effects of setting weight values according to the date of manufacture of terminal equipment)
In addition, the control unit sets a predetermined weight value that increases in the order of oldness or newest date of manufacture of the terminal device, and sets the addresses in the order of the higher weight value so as to transmit a call message to the terminal device. If necessary, the call messages can be transmitted in the order of the oldest or newest date of manufacture of the terminal device, for example, when data detected by the terminal device is sent to the control panel by a response message to the call message in a certain cycle. As the terminal device with the old manufacturing date or the new terminal device with the manufacturing date becomes shorter, the time delay from detection of fault data at the terminal device to reception by the control panel is shortened, and the real-time performance of fault monitoring is improved. Make it possible.

(Effect of setting by adding weight values according to multiple states of terminal equipment)
Further, the control unit sets a predetermined weight value according to a plurality of different states for the terminal device, sets addresses in descending order of the weight value obtained by adding the weight values set according to the plurality of states, and sets the terminal device For example, the weight value corresponding to the connection / non-connection of the terminal device and the weight value corresponding to the importance of the detection information of the terminal device are obtained, and this addition is performed. By sending a call message to the terminal device in descending order of the weight value and receiving a response message, for example, when data detected by the terminal device is sent to the control panel by a response message for the call message at a certain period, the added weight value The higher the terminal device, the shorter the time delay until the detection data is received by the control panel.

(Effects of controlling the number of terminal calls by weight value)
In addition, since the control unit changes the number of times of transmitting the call message to the terminal device according to the weight value, for example, the greater the number of fire alarms detected by the terminal device, the higher the number of call message transmissions with a higher weight value. As a result of the increase, the response message can be sent back from the terminal device in a specific state in a concentrated manner, and the delay time for fire detection or the like can be dynamically shortened.

[Outline of disaster prevention equipment transmission system]
(Disaster prevention monitoring equipment)
FIG. 1 is a block diagram showing the overall configuration of an R-type disaster prevention monitoring facility that monitors fire and gas leakage as an example of a disaster prevention facility in which the transmission system of the present invention is used.

  As shown in FIG. 1, transmission lines 12-1 and 12-2 are drawn out from an R-type receiver 10 toward a warning area of a facility. An analog sensor 14 is connected to the transmission line 12-1 as a terminal device, a repeater 16 is connected to the transmission line 12-1, and an on / off sensor is connected to the fire alarm line 18 drawn from the repeater 16. 20 and a transmitter 22 are connected, and a gas leak detector 24 is connected to another repeater 16.

  In addition, a plurality of repeaters 16 are connected to the transmission line 12-2, and the fire shutter 26, the fire door 28, the damper 30, and the alarm valve 32 of the sprinkler fire extinguishing equipment are connected as terminal devices via each repeater 16. doing. Among these, the fire shutter 26, the fire door 28, and the damper 30 are included in the control load, and the alarm valve 32 is included in the detector that outputs the flowing water detection signal.

  The analog sensor 14 and the repeater 16 have a transmission function for bidirectionally transmitting information to and from the receiver 10, and a unique address including the receiver 10 is assigned in advance. For example, when the maximum number of addresses is 256 addresses, the number of terminals that can be connected to each of the transmission lines 12-1 and 12-2 is less than 255 because the receiver address is excluded when the maximum number of addresses is 256 addresses. A terminal can be connected.

  The receiver 10 includes a receiver control unit 34, transmission units 36-1 and 36-2, a display unit 38, an operation unit 40, an acoustic alarm unit 42, a transfer unit 44, and a printer 46. In the following description, when there is no need to distinguish between the transmission lines 12-1 and 12-2 and the transmission units 36-1 and 36-2, they may be referred to as the transmission line 12 and the transmission unit 36.

  The receiver control unit 34 of the receiver 10 is configured by a computer circuit having a CPU, a memory, and various input / output ports, and performs predetermined receiver control by executing a program.

  Downstream signals from the receiver 10 to the analog sensor 14 and the repeater 16 are transmitted in the voltage mode. The voltage mode signal is transmitted as a voltage pulse that changes the voltage of the transmission line 12 between 18 volts and 30 volts, for example.

  In contrast, upstream signals from the analog sensor 14 and the repeater 16 are transmitted in a current mode. In this current mode, a signal current is passed through the transmission line 12 at the timing of bit 1 of the transmission data, and the upstream signal is transmitted to the receiver as a so-called current pulse train.

  The monitoring control by the receiver control unit 34 of the receiver 10 is as follows, taking the fire monitoring of the analog sensor 14 as an example. During normal monitoring, the receiver 10 transmits a broadcast batch AD conversion message including a batch AD conversion command at regular intervals, and the analog sensor 14 that receives the batch AD conversion message receives the batch AD conversion message. The smoke concentration or temperature is detected and held as sensor data.

  Subsequently, the receiver control unit 34 sequentially assigns terminal addresses based on a weight value order address table in which addresses are arranged in order of weight values indicating the state of the analog sensor 14, for example, the connected state and the unconnected state of the analog sensor 14. A call message containing the specified polling command is being sent.

  When the analog sensor 14 receives a call message having an address that matches the self-address, the analog sensor 14 transmits a response message including the sensor data held at that time to the receiver 10. For this reason, in the receiver 10, the sensor data of the analog sensor 14 is acquired by receiving the response message, the fire is judged, and the fire alarm operation is performed.

  Also, when a response message is not received for the calling message from the receiver control unit 34 at the time of starting up the equipment, it is determined that the analog sensor 14 at that address is not connected, and during normal operation, If the response message that has been received until then is no longer received, it can be determined that the analog sensor 14 has failed.

  Such monitoring control by the receiver control unit 34 is the same for the repeater 16 to which the on / off sensor 20 and the gas leak detector 24 are connected.

  In addition, the control of the repeater 16 to which the control load such as the fire shutter 26, the fire door 28, the damper 30 and the like is connected as a terminal device by the receiver control unit 34 is performed at regular intervals during normal monitoring. A broadcast batch AD conversion message including an AD conversion command is transmitted, and the control load that has received the batch AD conversion message detects the current control state and holds it as state detection data (status data).

  Subsequently, the receiver control unit 34 determines the terminal address based on the weight value order address table in which the addresses are arranged in the order of the weight values indicating the state of the control load such as the fire shutter 26, for example, the connected state and the unconnected state of the control load. When a call message including a polling command designated in sequence is transmitted and the control load such as the fire shutter 26 receives a call message of a polling command that matches the set address of itself, it includes state detection data held at that time. A response message is transmitted to the receiver 10. For this reason, the receiver 10 acquires the control load state detection data such as the fire shutter 26 by receiving the response message, and recognizes the current control position.

  The receiver control unit 16 includes, for example, a shutter closing command in the read message in which the address of the repeater 16 connected to the fire shutter 26 is set, for example, by linked control when a fire is determined from the sensor data of the analog sensor 14. Transmitting and performing control to close the fire shutter 26 when a fire occurs.

[Generate weight value order address table]
FIG. 2 is an explanatory diagram showing generation of a weight value order address table used for transmission of a call message of a terminal device by a receiver. FIG. 2A is an address in which initially set addresses are arranged in ascending order. FIG. 2B shows a weight value order address table in which addresses are arranged in order of weight values determined by the state of the terminal device. In order to simplify the description, the case where the maximum number of addresses is 16 addresses including the receiver 10 will be described as an example.

  As shown in FIG. 2 (A), the initially set address table 48 includes addresses, terminal device states, and weight values. In this example, the terminal device connection and terminal device states are as follows. Take the unconnected example. Different weight values are set for connection and non-connection of the terminal device. Note that the connection and non-connection of the terminal device means the presence and absence of the terminal device, and the use address and the free address when viewed from the address.

  The weight value is set to 1 when the terminal device is connected, and the weight value is set to 0 when the terminal device is not connected. When the equipment is started up, the terminal device connection is determined by calling a call message including a polling command in which addresses in ascending order arranged from the head to the tail are sequentially set in the address table 48 of FIG. When the response message is transmitted, it is determined that it is connected and the weight value is set to 1. On the other hand, when no response message is received, it is determined that the connection is not connected and the weight value is set to 0. The illustrated address table 48 is generated.

  Subsequently, a sort process for rearranging the weight values in descending order is executed for the address table 48 in FIG. 2A, and a weight value order address table 50 in which the addresses are rearranged in the weight value order shown in FIG. 2B is generated. To do. In this case, when there are a plurality of addresses having the same weight value, the addresses are arranged in ascending order.

  The receiver control unit 34 that has generated the weight value order address table 50 in this way transmits a broadcast batch AD conversion message to the analog sensor 14 at the arrival of a certain period, and detects and holds the sensor data. The addresses are sequentially read from the head position to the end of the weight value order address table 50 shown in FIG. 2B, set in the call telegram, and transmitted to the transmission line 12.

  For this reason, for example, when sensor data detected by the analog sensor 14 at a fixed period is sent to the receiver 10 by a response message to the call message, the analog sensor is set with a high weight value corresponding to the connection to the transmission line. 14 starts the transmission of the calling telegram by the receiver 10, reduces the time delay from the detection of sensor data by the analog sensor 14 to the reception of the sensor data by the receiver 10 to determine a fire, and real-time performance Can be improved.

[Monitoring control of disaster prevention monitoring equipment]
FIG. 3 is a flowchart showing the monitoring control by the receiver provided in the disaster prevention monitoring facility of FIG. 1, and the control operation is performed by the receiver control unit 34 provided in the receiver 10.

  As shown in FIG. 3, when the receiver 10 is started up by turning on the power, a call message in which addresses are sequentially set in order of A = 1 to 15 is transmitted to the analog sensor 14 in step S1 and a response message is received. In step S2, if a response message is received, the weight value is set to 1 as being connected. On the other hand, if no response message is received, the weight value is set to 0 as not connected. The address table 48 shown in FIG.

  In step S3, the address table 48 in FIG. 2A is rearranged in descending order of the weight value, and the weight value order address table 50 shown in FIG. 2B is generated. Subsequently, in step S4, a batch AD conversion message including a batch AD conversion command is transmitted by setting a broadcast address that can be received by all analog sensors 14, and the sensor data is detected and held by all analog sensors 14.

  Subsequently, the process proceeds to step S5, where the address at the head position in the weight value order address table 50 shown in FIG. 2B is read and set in the call message, and this call message is transmitted in step S6. The response message from the device is received, the sensor data contained in the response message is taken out, and processing such as fire judgment is performed.

  Subsequently, until the end address of the weight value order address table 50 is determined in step S8, the address of the next table position is read in step S9, and the process of sending the call message and receiving the response message in steps S6 and S7 is repeated. ing.

  Subsequently, when the address at the end of the table is determined in step S8, the process proceeds to step S10, where it is determined from the reception result of the response message in step S7 whether or not the analog sensor 14 has been connected or disconnected. If it is determined that there is a change in connection of 14 or unconnected, the process returns to step S2, and the connected or unconnected state in the current weight value order address table 50 is corrected, and again in order of weight value in step S3. A new weight value order address table is generated by rearranging, and the processing from step S4 is repeated in the same manner.

[Generation of weighted value order address table based on terminal device connection / disconnection and importance of detection information]
FIG. 4 is an explanatory diagram showing a process of generating a weight value order address table by setting weight values according to the importance of the detection information and connection / non-connection of terminal devices, and FIG. 5 is generated through the process of FIG. It is explanatory drawing which showed the weight value address table.

  In the address table 52 in which the initially set addresses shown in FIG. 4A are arranged in ascending order, the terminal device state becomes 1 when the analog sensor 14 is connected, as shown in FIG. 2A. In addition, a first weight value that is 0 when not connected is set, and in addition to this, a second weight value is set corresponding to the importance of smoke density and temperature detected by the analog sensor 14.

  In this embodiment, 1 type, 2 types, and 3 types which show the sensitivity of a photoelectric spot type sensor are utilized as the importance of detection information. There are 1 type, 2 types, and 3 types of photoelectric spot type detectors, 1 type is a sensitivity that operates within 30 seconds with smoke with a dimming rate of 5%, 2 types is 10% with a dimming rate of 10% Sensitivity that operates within 30 seconds with smoke of 3 types, and 3 types of sensitivity that operates within 30 seconds with smoke with 15% attenuation, assuming that a photoelectric spot type sensor is installed instead of the analog sensor 14 Sensitivity required in this case is used for the importance of detection information.

  Here, the second weight value according to the importance of the detection information is, in descending order of importance, the weight value is 3 for the first type sensitivity, the weight value is 2 for the second type sensitivity, and the weight value is set for the third type sensitivity. 1 is assumed.

  Next, for the address table 52 in which the first weight value and the second weight value are set, as shown in FIG. 4B, an intermediate address table having an added weight value obtained by adding the first weight value and the second weight value. 54 is generated.

  Subsequently, the weight value order address table 56 shown in FIG. 5C is generated by performing sort processing for rearranging the addresses in the descending order of the addition weight value for the intermediate address table 54.

  The generation of the weight value order address table 56 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 56 are changed. Call messages with addresses set in descending order are transmitted to the analog sensor 14, and response messages including sensor data are received and processed.

  For this reason, when the sensor data detected by the analog sensor 14 is sent back by a response message to the call message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, the importance of the detection information is increased. The higher the analog sensor 14, the shorter the time delay from the detection of sensor data to the reception by the receiver 10.

[Generation of weighted order address table based on connected / unconnected terminal devices and fire risk]
FIG. 6 is an explanatory diagram showing a weight value order address table by setting weight values according to connection and non-connection of terminal devices and fire risk.

  In the address table 58 in which the initially set addresses shown in FIG. 6 (A) are arranged in ascending order, the terminal device state becomes 1 when the terminal device is connected, as shown in FIG. 2 (A). A first weight value of 0 is set at connection, and in addition to this, a second weight value is set corresponding to the fire risk determined by the installation location of the analog sensor 14.

  Here, the degree of fire risk is high in places where the analog sensor 14 is installed, such as in a kitchen where fire is used or where smoking is performed, while it is low in places where no fire is used or where no smoke is used. In the present embodiment, the fire risk level is divided into three stages of high, medium and low, the weight value is 3 for the high fire risk level, the weight value is 2 for the fire risk level, and the weight value is 1 for the low fire risk level. .

  Next, for the address table 58 in which the first weight value and the second weight value are set, as shown in FIG. 4B, an intermediate address having an added weight value obtained by adding the first weight value and the second weight value. A table (not shown) is generated, and a sorting process for rearranging the addresses in descending order of the weight values added for the intermediate address table is performed, thereby generating the weight value order address table 60 shown in FIG.

  The generation of the weight value order address table 60 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 60 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when sensor data detected by the analog sensor 14 is sent back by a response message to the call message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, analog detection with a high risk of fire The time delay from the detection of the sensor data to the reception of the sensor data by the receiver 10 can be shortened as the device 14 becomes.

  Note that the weight values corresponding to connection and non-connection of the terminal device shown in FIG. 2B are always set in combination with the weight values corresponding to other states of the terminal device, which will be clarified in the following description. It becomes.

  In the address table 62 in which the initially set addresses shown in FIG. 7A are arranged in ascending order, the analog sensor 14 is connected in the same manner as shown in FIG. 2A as the state of the analog sensor 14. A first weight value that becomes 1 and becomes 0 when not connected is set. In addition to this, a second weight value is set corresponding to the smoke density detected by the analog sensor 14, and the analog sensor 14 The third weight value is set corresponding to the temperature detected in step (b).

  Since the analog sensor 14 shown in FIG. 1 includes a sensor for detecting smoke density and a sensor for detecting temperature as sensor data, weight values corresponding to respective magnitude relationships are set. In this embodiment, the smoke density and temperature are divided into three levels of high, medium and low, the weight value is 3 at the high level, the weight value is 2 at the medium level, and the weight value is 1 at the low level. Here, the analog sensor 14 of addresses 01 to 07 detects smoke density, and the analog sensor 14 of addresses 08 to 15 detects temperature.

  The setting of the second weight value and the third weight value corresponding to the smoke density and the temperature is performed by transmitting the call message from the receiver 10 and receiving the smoke concentration data or temperature data by the response message from the analog sensor 14 received as a predetermined value. Compared with the threshold value, the weight value is set in three levels of high, medium and low.

  For this reason, in the steady monitoring state, the smoke density is approximately 0% / m and the temperature is also room temperature. Therefore, the smoke density and temperature are at a low level, and the weight value 1 is set. In this case, for convenience of explanation, a case where three levels of high, middle, and low are generated is taken as an example.

  Next, for the address table 62 in which the first weight value, the second weight value, and the third weight value are set, an intermediate address table having an added weight value obtained by adding the first weight value, the second weight value, and the third weight value. (Not shown) is generated, and a sort process for rearranging the addresses in the descending order of the addition weight value for the intermediate address table is performed, thereby generating the weight value order address table 64 shown in FIG.

  The generation of the weight value order address table 64 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 64 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when the sensor data detected by the analog sensor 14 is sent back by a response message to the call message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, the smoke concentration and temperature are high. The analog sensor 14 can shorten the time delay from detection of sensor data to reception of the sensor data by the receiver 10.

FIG. 8 is an explanatory diagram showing a weight value order address table by setting weight values according to connection / non-connection of terminal devices and fire alarm history.

  In the address table 66 in which the initially set addresses shown in FIG. 8A are arranged in ascending order, the analog sensor 14 is connected in the same manner as shown in FIG. The first weight value is set to 1 and is set to 0 when not connected, and in addition to this, the second weight value is set corresponding to the number of times of the alarm detection history of the analog sensor 14.

  When the receiver control unit 34 of the receiver 10 shown in FIG. 1 determines a fire based on the sensor data from the analog sensor 14 connected to the transmission line 12, it issues a notification corresponding to the sensor address. The number of times is stored as a fire alarm history.

  In the present embodiment, the number of alarms indicating the fire alarm history of the analog sensor 14 is set in the address table 66 as the second weight value. Next, an intermediate address table (not shown) having an added weight value obtained by adding the first weight value and the second weight value is generated for the address table 66 in which the first weight value and the second weight value are set. By performing sort processing for rearranging addresses in descending order of the addition weight value for the address table, the weight value order address table 68 shown in FIG. 8B is generated.

  The generation of the weight value order address table 68 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 68 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when the sensor data detected by the analog sensor 14 is sent back by a response message to the call message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, the number of fire alarms is high. The analog sensor 14 can shorten the time delay from detection of sensor data to reception of the sensor data by the receiver 10.

[Generation of weighted order address table based on terminal device connection / no connection and non-fire alarm history]
FIG. 9 is an explanatory diagram showing a weight value order address table by setting weight values according to connection history of terminal devices and unconnected and non-fire alert history.

  In the address table 70 in which the initially set addresses shown in FIG. 9A are arranged in ascending order, the analog sensor 14 is connected to the analog sensor 14 in the same manner as shown in FIG. 1 is set, and the first weight value is set to 0 when not connected, and in addition to this, the second weight value is set corresponding to the number of non-fire alarms that are the non-fire alarm history of the analog sensor 14. Yes.

  When the receiver control unit 34 of the receiver 10 shown in FIG. 1 judges a fire based on the sensor data from the analog sensor 14 connected to the transmission line 12 and outputs a fire alarm, a disaster prevention person or the like Determines a predetermined series of operations that are performed when there is a non-fire by confirming the fire site, for example, operation of acoustic alarm stop switch, operation of district acoustic stop switch, operation of recovery switch or predetermined non-fire alarm notification operation Then, it recognizes the non-fire report and counts up the number of occurrences of the non-fire report corresponding to the sensor address to store it as the non-fire report history.

  In the present embodiment, the number of non-fire alarms indicating the non-fire alarm history of the analog sensor 14 is set in the address table 70 as the second weight value. Next, for the address table 70 in which the first weight value and the second weight value are set, an intermediate address table (not shown) having an added weight value obtained by adding the first weight value and the second weight value is generated. By performing a sort process for rearranging addresses in descending order of the addition weight value for the address table, a weight value order address table 72 shown in FIG. 9B is generated.

  The generation of the weight value order address table 72 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 72 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when the sensor data detected by the analog sensor 14 is sent back by a response message to the calling message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, the number of non-fire alerts The more analog sensors 14, the shorter the time delay from when the sensor data is detected until the receiver 10 receives the sensor data.

[Generation of weighted order address table based on terminal device connection / no connection and non-fire alarm history]
FIG. 10 is an explanatory diagram showing a weight value order address table by setting weight values according to connection and disconnection of terminal devices and failure history.

  In the address table 74 in which the initially set addresses shown in FIG. 10A are arranged in ascending order, the analog sensor 14 is connected in the same manner as shown in FIG. A first weight value that is 1 and is 0 when not connected is set, and in addition to this, a second weight value is set corresponding to the number of occurrences of failure that is a failure history of the analog sensor 14.

  When the receiver control unit 34 of the receiver 10 shown in FIG. 1 does not receive a response message even if a call message is transmitted to the analog sensor 14 connected to the transmission line 12, the analog sensor 34 It is determined that the failure is 14 and a failure alarm is output. When this failure is determined, the failure occurrence count is counted up in correspondence with the detector address and stored as a failure history.

  In the present embodiment, the number of failure occurrences indicating the failure history of the analog sensor 14 is set in the address table 74 as the second weight value. Next, an intermediate address table (not shown) having an added weight value obtained by adding the first weight value and the second weight value is generated for the address table 74 in which the first weight value and the second weight value are set. By performing a sort process for rearranging addresses in the descending order of the added weight value for the address table, a weight value order address table 76 shown in FIG. 10B is generated.

  The generation of the weight value order address table 76 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 76 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when sensor data detected by the analog sensor 14 is sent back by a response message to the call message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, an analog with a large number of failure occurrences. The sensor 14 can shorten the time delay from detection of sensor data to reception of the sensor data by the receiver 10.

[Generation of weighted order address table based on connection / disconnection of terminal equipment and date of manufacture]
FIG. 11 is an explanatory view showing a weight value order address table by setting weight values according to connection and disconnection of terminal devices and failure history.

  In the address table 78 in which the initially set addresses shown in FIG. 11A are arranged in ascending order, the state of the analog sensor 14 is the same as that shown in FIG. A first weight value that becomes 1 and becomes 0 when not connected is set, and in addition, a second weight value that becomes higher as the manufacturing date of the analog sensor 14 becomes older is set.

  When the analog detector 14 is installed in the alert area in the disaster prevention monitoring facility shown in FIG. 1, it is assumed that the date of manufacture is different within a range of several months, for example, and the analog sensor that has failed during operation is detected. If the device 14 is replaced with a new one or a sensor is added, there will be a new production date.

  Therefore, at the construction stage of the disaster prevention monitoring facility shown in FIG. 1, the manufacturing date is set corresponding to the sensor address included in the property data stored in the receiver 10, and the receiver 10 is turned on when the power is turned on. When the date is raised, the date of manufacture of the analog sensor 14 is acquired from the property data and set in the address table 78, and a second weight value that is higher as the date of manufacture is older is set.

  In the present embodiment, since the distinction between the daily units is not necessary, the second weight value is set corresponding to the production date, with the distinction between the monthly units. In addition, the second weight value may be set corresponding to the year of manufacture, with yearly distinction.

  Here, the manufacturing date of the address 01 in the address table 78 is greatly different from other manufacturing dates, and it can be seen that the analog sensor 14 at the address 01 has been replaced with a new one due to a failure.

  When the address table 78 is generated in this way, the address table 78 in which the first weight value and the second weight value are set has an added weight value obtained by adding the first weight value and the second weight value. An intermediate address table (not shown) is generated, and a sort process for rearranging the addresses in the descending order of the added weight value is performed on the intermediate address table, thereby generating a weight value order address table 80 shown in FIG.

  The generation of the weight value order address table 80 corresponds to the processing of steps S1 to S3 in the flowchart of FIG. 3, and subsequently, as shown in steps S4 to S10, the weight values given in the weight value order address table 80 are changed. Call messages with addresses set in descending order are transmitted to the terminal, and response messages including sensor data are received and processed.

  For this reason, when the sensor data detected by the analog sensor 14 is sent back by a response message to the calling message from the receiver 10 by transmitting a message including a batch AD conversion command at regular intervals, the old analog of the manufacturing date is used. The sensor 14 can shorten the time delay from detection of sensor data to reception of the sensor data by the receiver 10.

  Further, as a modification of the present embodiment, a weight value order address table in which a second weight value that becomes higher as the date of manufacture is higher is generated, and sensor data is detected as the analog sensor 14 is manufactured with a new date of manufacture. After that, the time delay until the receiver 10 receives the sensor data may be shortened.

  Note that the weight value may be set according to the use period instead of the manufacturing date. That is, the older the manufacturing date of the terminal device, the longer the usage period, and the newer the manufacturing date, the shorter the usage period. Therefore, the longer the usage period of the terminal device or the shorter the usage period of the terminal device. The weight value may be set so as to be higher.
