Description

The present invention relates to a remote monitoring interface for fire alarm equipment.

  Conventional fire-fighting equipment such as automatic fire alarm equipment is provided not only in buildings that are fire prevention objects, but also in other various buildings. Such fire fighting facilities need to maintain and manage their functions at all times so that they can respond appropriately even when an unforeseen situation of fire occurs.

In order to report such fire-fighting equipment (disaster prevention equipment) information accurately and quickly to remote managers, etc., each disaster prevention monitoring panel is connected to a server device via a telephone line. A system for sending an e-mail to a mobile phone via the Internet has been proposed (for example, see Patent Document 1). The disaster prevention monitoring panel in this conventional system has an input / output control I / F for connecting to a server device.

  However, in the above conventional example, the server apparatus may not be able to receive normal information due to a communication abnormality or the like.

  In other words, in a system in which each disaster prevention monitoring panel is connected to a server device via a communication line, and the server device remotely monitors each disaster prevention monitoring panel, the communication status must be confirmed in order to reliably perform the remote monitoring function. It is necessary to accurately transmit information to the server device while performing it.

According to the present invention, a fire receiver installed for each property is received by the server side when data transmission from the interface device to the server side is not completely performed in the interface device connected to the server via the network. The data you want to send can be transmitted without fail, and there is a difference between the fire receiver status of each property and the status of each property recognized by the support center. Therefore, an object of the present invention is to provide an interface device for remote monitoring of a fire alarm facility that can perform reliable remote monitoring.

  According to the first aspect of the present invention, when the fire receiver installed for each property is connected to the server via the network, the data transmission from the interface device to the server is not completely performed. In addition, the information received on the server side does not end halfway, but the data to be transmitted can be transmitted reliably, and the status of the fire receiver of each property and the status of each property recognized by the support center There is no difference between them, and there is an effect that reliable remote monitoring can be performed.

  According to the second aspect of the present invention, since the communication state of the network is confirmed before data transmission from the interface device, the data transmission to the server can be reliably performed, thereby improving the communication state. Otherwise, there is an effect that the data transmission can be skipped and erroneous transmission of data to the support center can be prevented in advance.

  According to invention of Claim 3, when a network is radio | wireless communication, there exists an effect that it can respond to the case where a communication state becomes bad unexpectedly.

  According to the fourth aspect of the present invention, there is an effect that data can be transmitted to the center server even when the radio wave state is not recovered.

  The control means 10 is an example of a means for transmitting data to the server via the wired communication means in a state where the interruption detection means outputs the interruption or a state where the communication confirmation means confirms that the normal connection is impossible.

  The transfer signal receiving means 20 has a receiver I / F 21 and an I / O circuit 22 and is a means for receiving transfer signals from the fire receivers RE1, RE2,.

  The receiver I / F 21 is an interface of the RS 422A to which the fire receiver RE1 that can output a message by data is connected.

  The I / O circuit 22 is a circuit that receives a contact signal that is a signal notifying that the fire receiver RE2 is turned on and off, and is a receiving circuit that receives a relay output from the contact. While the switch status is input, it also serves as an output circuit for performing control output of various indicator lamps.

  The control means (CPU) 10 mainly converts the transferred information into packet data when the transfer signal is input via the receiver I / F 21 or the I / O circuit 22, and transmits the packet data via the transmitter 60. To the server SV1. The control unit 10 is a unit that blocks data transmitted by the transmission device 60 by discarding the transfer signal received from the transfer signal receiving unit 20 when the cutoff switch 24 is turned on.

  Moreover, the control means 10 monitors the power supply voltage of the power supply circuit 50, and when this power supply voltage falls below a predetermined voltage, it shows that the said power supply voltage fell below the predetermined voltage via the communication apparatus 60. This is means for transmitting a power supply lowering signal to the server SV1 and then stopping the operation of the control means 10.

  The cutoff switch 24 is a switch that is turned on when transmission from the transmission device 60 to the network NW is cut off. Specifically, the output of the transmission device I / F 40 that the transmission device I / F 40 should send to the transmission device 60. This switch cuts off the signal. When the signal is cut off by the cut-off switch 24, the fire signal or the like is cut off during the test for confirming the operation of the fire alarm equipment (operations in steps S43 and S52 described later).

  Here, a brief description will be given of the transfer signal received by the remote monitoring interface device 100 from the fire receivers RE1, RE2,. Signals as terminal information such as fire signals, terminal equipment operation signals, transmission abnormal signals, restoration signals, printer stop signals, acoustic stop signals, signals as receiver status information such as test abnormal signals, and other states such as time information Changes in various states relating to fire alarm equipment, such as signals as information, are transferred. In addition, various states can be captured in response to a request from the server SV1.

  Next, the operation of the above embodiment will be described.

  3, 4, 5, 6, and 7 are flowcharts illustrating the operation of the remote monitoring interface device 100 in the above embodiment.

  First, the power is turned on and initialized (S1). If the setting of the dip switch or the like is abnormal (S2), an error is displayed by the indicator lamp 25 (S3). If the setting is normal (S2), it is determined whether or not the connection to the fire receivers RE1, RE2,... Is completed (S4), and if the connection is completed (S4), the center SC is contacted. A transmission operation for notifying "establishing connection with receiver" is executed (S100).

  Details of the transmission operation (S100) are shown in FIG.

  When the transmission operation (S100) is finished, as shown in FIG. 4, the interface apparatus 100 is normally AC driven, and the AC power source is not driven due to disconnection of the AC adapter 52, failure, power failure, etc. S21), switching to driving by the battery 51 (S22), if notifying the customer service center SC that switching to driving by the battery 51 has been made (S23), the remaining capacity of the battery 51 is checked as the power supply voltage (S31) If the battery 51 has a sufficient voltage (S31), the state change (presence / absence of reception of a transmission signal) in the fire receivers RE1, RE2,... Is checked (S41). If there is no change in the state, the process proceeds to step S51.

  If the status of the fire receivers RE1, RE2,... Changes (S41) and that is a change in the status of the terminal, that is, the message signal is terminal information (S42), if the message blocking is being canceled (S42) S43), the generated data (transmission signal) within a predetermined time is collected (S44), and a transmission operation for notifying the center SC of the “state change content (transmission signal)” is executed (S300). If the message blocking is not being canceled (S43), the process proceeds to step S51. If the state change in step S41 is not a change in the state of the terminal (S42), the generated data (transmission signal) within a predetermined time is collected (S44), and the above-mentioned state change content (transfer) is transferred to the center SC. The transmission operation of notifying the “information signal” ”is executed (S300).

  In step S23 shown in FIG. 4, if the customer service center SC has not been notified of switching to driving by the battery 51, as shown in FIG. 5, a transmission for notifying the center SC of a “remote I / F power failure” is sent. The operation (S400) is executed, and the process returns to step S21.

  Details of the transmission operation (S400) are shown in FIG.

  In step S31 shown in FIG. 4, if it is found that the power supply voltage level of the battery 51 is low and the remaining capacity is insufficient, as shown in FIG. 6, the center SC is notified of "power supply voltage drop". The transmission operation (S500) is executed, the communication with the fire receivers RE1, RE2,... Is stopped (S36), the power supply circuit 50 is turned off (S37), and the operation is terminated so as not to make useless movement. .

  After the transmission operation (S300) shown in FIG. 4, as shown in FIG. 7, in step S51, it is determined whether there is a request / control from the customer service center SC, and there is a request / control from the customer service center SC. For example, it is determined whether or not the remote monitoring interface device 100 is releasing the message blocking (S52), and if the remote monitoring interface device 100 is not releasing the message blocking, is the status request / control performed? It is determined whether or not (S53). The “transfer” is an operation in which the fire reception RE1, RE2,... Sends status information to the customer service center SC, and is an operation performed in response to an instruction from the customer service center SC.

  If it is status request / control, that is, request control other than terminal information as a transfer signal (S53), a transmission operation for notifying the center SC of “response data corresponding to the request / control from the center SC” ( S700) is executed, and the process returns to step S21.

  If the status is not request / control (S53), the process returns to step S21 without executing the transmission operation (S700).

  Next, in the communication guarantee system (transmission operation) which is the main of the invention, as shown in FIGS. 8 to 12, the interface device 100 transmits to the customer service center SC generated in the flow of FIGS. This is an operation for transmitting power data to the customer service center SC by the transmission operations (S100, S300, S400, S500, S700) shown in FIGS.

  FIG. 8 is a flowchart showing the transmission operation (S100) in the above embodiment.

  First, it is determined whether or not data that has failed to be transmitted in the past is stored in the storage unit 13. If there is no data that has failed to be transmitted in the past (S101), connection establishment with the receiver is selected as transmission data ( On the other hand, if there is data that failed to be transmitted in the past (S101), establishment of the receiver and data that failed to transmit in the past are selected as transmission data (S103), and the state of the radio wave is examined (S103). S104).

  If the radio wave condition is good (S104), a call is sent to the center SC via the transmission device 60 (S105), and if a telephone line with the center SC is established (S106), communication confirmation data is transmitted. (S107), it is checked whether or not response data from the center SC has been received (S108). If the response data from the center SC is received, the transmission device 60 performs the operation of transmitting the selected data via the transmission device 60, assuming that the transmission device 60 can confirm normal connection to the center SC. That is, if the selected transmission data is transmitted via the transmission device 60 (S109), the radio wave condition is good (S110), and response data from the center SC is received (S111), the center SC selects the selected data. Assuming that data could be transmitted normally, the data that failed to be transmitted in the past in the storage unit 13 is deleted, and the telephone line is disconnected (S112).

  If the telephone line with the center SC is not established (S106) and the number of retries is within the specified range (S113), the process returns to step S105. If the number of retries is not specified (S113), and if the state of the radio wave is bad in step S104, the transmission data that failed to be transmitted is stored because the selected data could not be transmitted normally to the center SC. Store in the unit 13 (S118).

  If the response data from the center SC has not been received (S108) and the number of retries is within the specified range (S114), the telephone line is disconnected (S117), and the process returns to step S105. If the number of retries is not specified (S114), it is determined that the selected data could not be transmitted normally to the center SC, and the transmission data that failed to be transmitted is stored in the storage unit 13 (S116), and the process proceeds to step S112.

  When the radio wave condition is bad (S110) or when response data from the center SC has not been received (S111), it is checked whether the number of retries is within the specified range or not specified (S115). If so, the process proceeds to step S117 and step S105. If it is out of the retry count, the process proceeds to S116. Then, the process proceeds from step S116 to step S112, and the telephone line is disconnected.

  FIG. 9 is a flowchart showing the transmission operation (S300) in the above embodiment.

  In the transmission operation (S300), in the transmission operation (S100), the state change content is selected as transmission data instead of step S102 (S302), and instead of step S103, the state change content and the past The data that failed to be transmitted is selected (S303). Other than these, the transmission operation (S100) is the same.

  FIG. 10 is a flowchart showing the transmission operation (S400) in the above embodiment.

  In the transmission operation (S400), in the transmission operation (S100), a remote I / F power failure is selected as transmission data instead of step S102 (S402), and instead of step S103, remote I / F is selected as transmission data. A power failure and data that failed to be transmitted in the past are selected (S403). Other than these, the transmission operation (S100) is the same.

  FIG. 11 is a flowchart showing the transmission operation (S500) in the above embodiment.

  In the transmission operation (S500), in the transmission operation (S100), instead of step S102, power supply voltage drop is selected as transmission data (S502), and instead of step S103, power supply voltage drop is used as the transmission data. The data that failed to be transmitted is selected (S503). Other than these, the transmission operation (S100) is the same. In the transmission operation (S500), if transmission fails (S116, S118), the power supply circuit 50 is turned off in the subsequent step S37, so that the failed transmission data cannot be retransmitted to the center SC. Therefore, in the transmission operation (S500), if transmission fails (S116, S118), retransmission may be continued until data transmission to the center SC is possible.

  FIG. 12 is a flowchart showing the transmission operation (S700) in the above embodiment.

  The transmission operation (S700) selects response data to the request / control from the center SC as transmission data instead of step S102 in the transmission operation (S100) (S702), and as transmission data instead of step S103. Then, response data to the request / control from the center SC and data that failed to be transmitted in the past are selected (S703). Other than these, the transmission operation (S100) is the same.

  FIG. 13 is a diagram illustrating an example of transmission of transmission data to the customer service center SC during the transmission operation and reception of response data transmitted from the customer service center SC in response to the transmission data in the interface device 100. .

  The transmission data is divided into a plurality of transmission packets according to the data amount and transmitted. For example, in the example shown in FIG. 13, the transmission data is divided into n transmission packets, and each transmission packet has a serial number and a transmission text as the divided transmission data.

  Response data is transmitted from the customer service center SC to each transmission packet transmitted from the interface device 100. This response data is constituted by a response packet having a serial number and a response text.

  The interface apparatus 100 can determine that the transmission data has been normally transmitted to the customer service center SC by receiving a corresponding response packet for each transmission packet.

  When the remote monitoring interface device 100 transmits data to the center SC, the remote monitoring interface device 100 determines whether the radio wave condition is good or bad (S110) and whether or not response data is received from the center SC (S111). It detects that the data transmission from the device 60 has been blocked, and outputs a blocking signal indicating that the data transmission from the transmitting device 60 has been blocked. Then, during the data transmission, the transmission device 60 holds the data being transmitted based on the cutoff output (S116, S118).

  Further, after the output of the cutoff signal is stopped, the held data is retransmitted via the transmission device 60. In the first embodiment, when the data to be transmitted is generated and the transmission operation (S100, S300, S400, S500, S700) needs to be performed, if the radio wave condition is good (S104), the interruption signal Therefore, the held data is retransmitted via the transmission device 60.

  As a result, when the data transmission from the interface device to the server side is not performed completely, the information received on the server side is not terminated halfway, and the data to be transmitted can be transmitted reliably. No difference occurs between the state of the fire receiver and the state of each property recognized by the support center, and remote monitoring can be performed reliably.

  In this embodiment, the operation for retransmitting the stored data via the transmission device 60 requires data to be transmitted, and the transmission operation (S100, S300, S400, S500, S700) needs to be performed. Step S101 for determining whether there is data that has failed to be transmitted in the past, for example, before step S21 in FIG. 4 in the flow of the circulation monitoring operation from FIG. 4 to FIG. If there is a step for performing a transmission operation when there is data that failed to be transmitted and data that has failed to be transmitted, even if no new data to be transmitted has occurred, the held data is transmitted to the transmission device 60. Can be resent quickly. As a step of the transmission operation in this case, a step of selecting only data that has failed in the past as transmission data may be provided instead of steps S101 to S103 in the transmission operation (S100).

  In addition, the remote monitoring interface device 100 determines whether the transmitter 60 can be normally connected to the center SC before transmitting data to be transmitted, so as to determine whether the radio wave condition is good or bad (S104). ) To determine whether or not a telephone line has been established with the center SC (S106), to transmit communication confirmation data (S107), and to determine whether response data is received from the center SC (S108). To do. When it is confirmed that normal connection is possible, data to be transmitted is transmitted via the transmission device 60.

  As a result, when transmitting information (data) to be transmitted, after the connection process with the center is normally completed once, information for communication confirmation is transmitted, and then the information transmission completion process is normally completed. Otherwise, since the information to be transmitted is not transmitted, the information can be reliably transmitted to the center.

  That is, since the information is transmitted regardless of the other party's state, the conventional problem that the generated information may not be notified to the center can be solved.

  Further, when the remote monitoring interface device 100 converts the transmission signal into data, the remote monitoring interface device 100 aggregates the plurality of transmission signals, creates data to be transmitted, and transmits the data via the transmission device 60. In other words, there are various information such as terminal information and receiver status information as the transfer signal. For example, the fire signal of the terminal information and the recovery signal of the receiver status information are a series of operations when a fire is detected. It is conceivable that each transfer signal is generated in a short period. Therefore, if the generated data (transmission signal) within a predetermined period is aggregated and data is transmitted as data to be transmitted as in step S44, a plurality of events are generated instead of transmitting the generated events (transmission signal) as they are. Since only one transmission operation is performed, the transmission time can be shortened and simplified, and reliable data communication can be performed.

  In addition, the remote monitoring interface device 100 mainly receives a transmission signal from the fire receivers RE1, RE2,..., Converts the information based on the received transmission signal into data, and uses a mobile phone communication network. To send data. During maintenance and inspection of the fire alarm facility, the interface device 100 can block communication on the data transmission side so that unnecessary information is not transmitted to the customer service center SC. If the cutoff switch 24 is turned on, remote monitoring is possible. Even if the interface device 100 receives a message from the fire receivers RE1, RE2,..., Data is not transmitted to the network NW.

  Further, the remote monitoring interface device 100 has its own power supply circuit 50, and the control means 10 monitors the supply voltage of the power supply circuit 50. When the monitored voltage drops, the remote monitoring interface device 100 supplies the power to the customer service center SC. After transmitting data indicating that the power supply of the circuit 50 has dropped, the operation (the operation of the remote monitoring interface device 100) is stopped. As a result, even if the voltage of the unique power supply circuit 50 provided in the remote monitoring interface device 100 decreases, erroneous data transmission to the customer service center SC based on unstable operation is not performed.

  That is, according to the above-described embodiment, it is possible to block communication on the data transmission side so that unnecessary information is not transmitted to the customer service server SC during maintenance inspection of the fire alarm facility.

Further, according to the above embodiment, in the remote monitoring interface device of the fire alarm facility having its own power supply, when the power supply voltage drops, data is erroneously transmitted to the customer service center SC based on unstable operation. There is nothing.

  In the second embodiment of the present invention, the control means 10 transmits data to the server via the transmission device 61 in the state where the interruption detection unit 11 outputs the interruption or the communication confirmation unit 12 confirms that the normal connection is impossible. It is characterized by doing. That is, although not illustrated, when the transmission operation (S100, S300, S400, S500, S700) is performed in the flowchart of the first embodiment, the second embodiment stores the transmission data that failed to be transmitted in the storage unit 13 ( Subsequent to each of S116 and S118), the control means 10 includes a step of transmitting transmission data that has failed to be transmitted to the center SC via the transmission device 61 and the Internet NW2.

  According to the second embodiment, even when the radio wave state does not recover, it is possible to cope with a case where the communication state becomes unexpectedly bad. In other words, since the Ethernet (registered trademark) circuit is mounted in the second embodiment, a normal Ethernet (registered trademark) connection (LAN connection) is possible for a portion outside the service area, and it can be connected to an intranet, the Internet, or the like.

That is, according to the second embodiment, it is possible to solve the conventional problem that it cannot be used outside the cellular phone line and cannot be used outside the service area.
