Description

Technical Field

[0001] This application relates to the field of software technology, and in particular to a networking method, device, storage medium and program product for an integrated subway fire protection system. Background Technology

[0002] In subway fire protection systems, a single subway station, especially a large transfer station, typically requires three or more integrated fire suppression systems to operate simultaneously. Additionally, if the subway fire protection system has a central fire control center, the operational information from the integrated fire suppression systems at different subway stations needs to be aggregated and transmitted to the central fire control center.

[0003] In subway fire protection systems, a master-slave network of integrated fire protection units is often used, with the slave unit sending operational information to the master unit, which then reports to its superior unit. However, in practice, this often presents challenges such as complex modifications to the network functionality and system instability. Summary of the Invention

[0004] In view of the above problems, this application provides a networking method, device, storage medium, and program product for integrated subway fire suppression systems to achieve rapid networking of integrated subway fire suppression systems. The specific solution is as follows:

[0005] The first aspect of this application provides a networking method for an integrated fire suppression system in a subway system. This networking method is applied to a subway fire suppression system, which includes multiple integrated fire suppression systems. The networking method is applied to a first integrated fire suppression system among the multiple integrated fire suppression systems. The networking method includes:

[0006] Obtain the master-slave network configuration of the local machine. The master-slave network configuration includes network roles. The network role is a master or a slave. When the network role is a master, the master-slave network configuration also includes slave configuration.

[0007] If the network role is the host, a first transmission control protocol TCP long connection is established and maintained with the second fire-fighting integrated machine as a slave according to the slave configuration; and the working information of the second fire-fighting integrated machine is received based on the first TCP long connection.

[0008] If the network role is slave, a second TCP long connection is established and maintained with the third fire protection integrated machine as the master; the working information of the local machine is sent to the third fire protection integrated machine based on the second TCP long connection. The second fire protection integrated machine and the third fire protection integrated machine are different fire protection integrated machines.

[0009] In one possible implementation, obtaining the master-slave network configuration of the local machine includes:

[0010] Obtain the network function status of the local machine based on the human-machine interface;

[0011] If the networking function is in the off state, disable the communication function of this machine;

[0012] If the networking function is enabled, the networking role is obtained based on the human-machine interface, and if the networking role is the master, the slave configuration is obtained based on the human-machine interface.

[0013] In one possible implementation, the slave configuration includes the controller number and Internet Protocol (IP) address of the second integrated fire protection unit;

[0014] The step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration includes:

[0015] Traverse the controller numbers in the slave configuration to determine the target second integrated fire protection unit to be connected;

[0016] The first TCP long connection is established with the target second fire-fighting integrated machine based on the IP address of the target second fire-fighting integrated machine;

[0017] If the first TCP long connection is successfully established, a first network subscription frame is sent to the target second fire-fighting integrated machine based on the first TCP long connection;

[0018] If the first network subscription frame is successfully sent and the first subscription response frame of the target second fire-fighting integrated machine is received, the first heartbeat frame is sent to the target second fire-fighting integrated machine at regular intervals based on the first TCP long connection;

[0019] If the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire-fighting integrated machine is received, return to the step of periodically sending the first heartbeat frame to the target second fire-fighting integrated machine based on the first TCP long connection.

[0020] In one possible implementation, the step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration, further includes:

[0021] If the first TCP long connection fails to be established, the controller number of the target second fire-fighting integrated machine is added to the TCP reconnection queue.

[0022] In one possible implementation, the step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration, further includes:

[0023] If the first network subscription frame fails to be sent, or if the first subscription response frame of the target second fire-fighting integrated machine is not received, the process returns to the step of sending the first network subscription frame to the target second fire-fighting integrated machine based on the first TCP long connection. When the number of times the first network subscription frame is sent reaches the corresponding first upper limit, the first TCP long connection is disconnected, and the controller number of the target second fire-fighting integrated machine is added to the TCP reconnection queue.

[0024] In one possible implementation, the step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration, further includes:

[0025] If the first heartbeat frame fails to be sent, or if the first heartbeat response frame of the target second fire-fighting integrated machine is not received, the process returns to the step of periodically sending the first heartbeat frame to the target second fire-fighting integrated machine based on the first TCP long connection. When the number of times the first heartbeat frame is sent reaches the corresponding second upper limit, the first TCP long connection is disconnected, and the controller number of the target second fire-fighting integrated machine is added to the TCP reconnection queue.

[0026] In one possible implementation, the step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration, further includes:

[0027] The controller number in the TCP reconnection queue is periodically traversed to determine the target second fire protection integrated machine to be connected to, and then the step of establishing the first TCP long connection with the target second fire protection integrated machine based on the IP address of the target second fire protection integrated machine is returned to be executed.

[0028] If the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire-fighting integrated machine is received, the controller code of the target second fire-fighting integrated machine is deleted from the TCP reconnection queue.

[0029] In one possible implementation, the step of establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine, which is a slave, according to the slave configuration, further includes:

[0030] Monitor the operating status of the machine;

[0031] If the running status is a restart status, return to the step of traversing the controller numbers in the slave configuration to determine the target second fire protection integrated machine to be connected.

[0032] In one possible implementation, establishing and maintaining a second TCP long connection with the third integrated fire protection unit, which acts as the host, includes:

[0033] If the third fire-fighting integrated machine receives a second network subscription frame sent based on the second TCP long connection, retrieve the host whitelist of the local machine;

[0034] If the third fire-fighting integrated machine is in the host whitelist, a second subscription response frame is sent to the third fire-fighting integrated machine based on the second TCP long connection;

[0035] If a second heartbeat frame is received from the third fire-fighting integrated unit based on the second TCP long connection, a second heartbeat response frame is sent to the third fire-fighting integrated unit based on the second TCP long connection.

[0036] A second aspect of this application provides a networking device for an integrated fire suppression system in a subway system. The networking device is applied to a subway fire suppression system comprising multiple integrated fire suppression systems. The networking device is applied to a first integrated fire suppression system among the multiple integrated fire suppression systems. The networking device includes:

[0037] The configuration acquisition module is used to acquire the master-slave network configuration of the local machine. The master-slave network configuration includes network roles. The network role is a master or a slave. When the network role is a master, the master-slave network configuration also includes slave configuration.

[0038] The master-slave networking module is used to establish and maintain a first transmission control protocol TCP long connection with the second fire-fighting integrated machine as a slave, according to the slave configuration, if the networking role is master; to receive the working information of the second fire-fighting integrated machine based on the first TCP long connection; if the networking role is slave, to establish and maintain a second TCP long connection with the third fire-fighting integrated machine as master; and to send the working information of the machine to the third fire-fighting integrated machine based on the second TCP long connection, wherein the second fire-fighting integrated machine and the third fire-fighting integrated machine are different fire-fighting integrated machines.

[0039] A third aspect of this application provides a computer program product, including computer-readable instructions, which, when executed on a fire-fighting integrated machine, cause the fire-fighting integrated machine to implement the networking method of the subway fire-fighting integrated machine described in the first aspect or any implementation thereof.

[0040] The fourth aspect of this application provides a computer storage medium carrying one or more computer programs. When the one or more computer programs are executed by a fire-fighting integrated machine, the fire-fighting integrated machine can realize the networking method of the subway fire-fighting integrated machine described in the first aspect or any implementation thereof.

[0041] A fifth aspect of this application provides an integrated fire protection unit, comprising at least one computing board and a memory connected to the computing board, wherein:

[0042] The memory is used to store computer programs;

[0043] The computing board is used to execute the computer program so that the integrated fire protection unit can realize the networking method of the integrated subway fire protection unit of the first aspect or any implementation of the first aspect.

[0044] By utilizing the above technical solution, this application provides a networking method, device, storage medium, and program product for an integrated fire protection unit in a subway system. Applied to a first integrated fire protection unit in a subway fire protection system, it obtains its own master-slave networking configuration. This configuration includes networking roles, which can be either master or slave. When the role is master, the configuration also includes slave configuration. If the role is master, a first TCP long connection is established and maintained with a second integrated fire protection unit acting as a slave, based on the slave configuration. The system receives operational information from the second integrated fire protection unit based on this first TCP long connection. If the role is slave, a second TCP long connection is established and maintained with a third integrated fire protection unit acting as a master, based on this second TCP long connection. The system sends its own operational information to the third integrated fire protection unit via the second TCP long connection. The second and third integrated fire protection units are different fire protection units. This application achieves rapid networking between integrated fire protection units via TCP long connections through master-slave networking configuration, improving the convenience and stability of the networking function in the subway fire protection system.

[0053] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0054] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0055] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0056] See Figure 1 , Figure 1 This is a system structure diagram of a subway fire protection system provided as an embodiment of this application. Figure 1 As shown in the embodiment of this application, the subway fire protection system includes multiple integrated fire protection units. Figure 1 The example uses three integrated fire protection units. A single integrated fire protection unit mainly includes a computing board and a human machine interface (HMI), and connects to corresponding subway fire protection peripherals, enabling information display and control of the fire protection peripherals.

[0057] In this embodiment, the computing board is responsible for processing information from fire protection peripherals and uploading it to the human-machine interface (HMI) for display. It also receives commands from the HMI and connects to other integrated fire protection units to synchronize slave information with the master unit. The HMI displays the processed and uploaded information from the fire protection peripherals to subway firefighters. Simultaneously, subway firefighters can input master-slave network configurations through the HMI. It should be noted that the networking method for an integrated subway fire protection unit provided in this embodiment can be executed by the computing board.

[0058] In practical applications, before setting up the network for the integrated fire protection device, subway firefighters must successfully log in with an account and password that meet the operating permissions before they can input the master-slave network configuration into the human-machine interface of the integrated fire protection device.

[0059] It should be noted that fire protection peripherals mainly include smoke detectors, heat detectors, manual fire alarm buttons, input / output modules, isolation modules, and audible / visual alarms. In a subway fire protection system, when an abnormality occurs in a fire protection peripheral, such as a smoke detector detecting smoke exceeding its threshold, or a communication failure in the input / output module due to aging internal wiring, the peripheral will first report the relevant information to the integrated fire protection unit it is connected to. If the integrated fire protection unit is the master unit, it does not need to send information from the fire protection peripherals to slave units; however, if the integrated fire protection unit is a slave unit, after receiving the information reported by the master unit, it will synchronously send the information to the other integrated fire protection unit acting as its master unit. The master integrated fire protection unit can control the fire protection peripherals of the slave integrated fire protection units. Therefore, the networking of integrated fire protection units in the subway is crucial to the stability and ease of use of the subway fire protection system.

[0060] See Figure 2 , Figure 2 This is a flowchart illustrating a networking method for an integrated subway fire suppression system provided in an embodiment of this application. Figure 2 As shown in the embodiment of this application, a networking method for an integrated fire protection unit in a subway is provided. This networking method is applied to a subway fire protection system, which includes multiple integrated fire protection units. The networking method is applied to the first integrated fire protection unit (hereinafter referred to as integrated fire protection unit A) among the multiple integrated fire protection units, and may include steps S101 to S103. These steps are described in detail below.

[0061] S101, obtain the master-slave network configuration of the local machine. The master-slave network configuration includes the network role. The network role is either master or slave. When the network role is master, the master-slave network configuration also includes the slave configuration.

[0062] In this embodiment of the application, the subway fire-fighting integrated machine A can obtain the master-slave network configuration of the machine, which includes at least the network role (master or slave). If the network role is master, the master-slave network configuration also includes the slave configuration (specifically specifying the fire-fighting integrated machine as the slave). Conversely, if the network role is slave, it is not necessary to specify the fire-fighting integrated machine as the master.

[0063] In one possible implementation, subway firefighters can input master-slave network configuration information into the integrated fire-fighting unit A via its HMI (Human Machine Interface). See also... Figure 3 , Figure 3 This is a partial flowchart illustrating a networking method for an integrated subway fire suppression system provided in an embodiment of this application. Figure 3 As shown in the embodiment of this application, a networking method for an integrated subway fire fighting machine is provided. Step S101, "obtaining the master-slave networking configuration of the local machine", may include steps S201 to S203. These steps are described in detail below.

[0064] S201, obtain the networking status of the local machine based on the human-machine interface.

[0065] S202, If the networking function is off, disable the communication function of this machine.

[0066] S203, if the networking function is enabled, obtain the networking role based on the human-machine interface, and if the networking role is the master, obtain the slave configuration based on the human-machine interface.

[0067] In this embodiment, when subway firefighters input master-slave networking configuration into the human-machine interface of the integrated fire protection unit A, they can specify the networking function status of the integrated fire protection unit A by turning the networking function switch on or off. After turning on the networking function switch, the subway firefighters can further specify whether it is a master or a slave, and further specify a slave for the master. In response, the integrated fire protection unit A obtains its own networking function status by detecting the networking function switch, which is either on or off. If the networking function status is off, the integrated fire protection unit A disables its own communication function, that is, disconnects its communication with other integrated fire protection units, and thus disables the networking function. If the networking function status is on, the integrated fire protection unit A further obtains the networking role, and if the networking role is master, it obtains the slave configuration (specifically specifying the integrated fire protection unit to be used as a slave).

[0068] In other words, in this embodiment of the application, subway firefighters do not need to input host configuration for the fire-fighting integrated machine A, which is a slave machine. That is, when the fire-fighting integrated machine A is a slave machine, it can respond to the networking requirements of any fire-fighting integrated machine and can be a slave machine of any fire-fighting integrated machine.

[0069] It should be noted that if the integrated fire protection unit is the master unit, it does not need to send information about fire protection peripherals to the slave units; however, if the integrated fire protection unit is a slave unit, it will simultaneously send the information reported by the other integrated fire protection unit, which is its master unit, to the other integrated fire protection unit. The master integrated fire protection unit can control the fire protection peripherals of the slave integrated fire protection units. Therefore, the networking of integrated fire protection units in the subway is crucial to the stability and ease of use of the subway fire protection system.

[0070] S102, if the network role is the host, establish and maintain a first transmission control protocol TCP long connection with the second fire protection integrated machine as the slave according to the slave configuration; receive the working information of the second fire protection integrated machine based on the first TCP long connection.

[0071] In this embodiment of the application, if the networking role of the fire protection integrated machine A is the host, then the second fire protection integrated machine (hereinafter referred to as fire protection integrated machine B) is determined as its slave according to the slave configuration, and a TCP (Transmission Control Protocol) long connection (i.e. the first TCP long connection) is established and maintained with the fire protection integrated machine B, and the working information of the fire protection integrated machine B (including the fire protection peripheral information of the fire protection integrated machine B) is received based on the first TCP long connection.

[0072] In one possible implementation, the host can establish and maintain a long-lived TCP connection with the slave via network subscription frames and heartbeat frames. See also Figure 4 , Figure 4 This is another schematic flowchart illustrating a networking method for an integrated subway fire suppression system provided in this application embodiment. (See attached diagram.) Figure 4 As shown in the embodiment of this application, a networking method for a subway fire-fighting integrated machine is provided. The slave configuration includes the controller number and IP (Internet Protocol) address of the second fire-fighting integrated machine. Step S102, "establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine as a slave according to the slave configuration", may include steps S301 to S305. These steps are described in detail below.

[0073] S301, traverse the controller numbers in the slave configuration to determine the target second fire protection integrated machine to be connected.

[0074] In this embodiment, the fire protection integrated machine A traverses the controller numbers in its slave configuration and takes the fire protection integrated machine B corresponding to the currently traversed controller number as the target second fire protection integrated machine to be connected (hereinafter referred to as fire protection integrated machine BX).

[0075] S302, establish a first TCP long connection with the target second fire protection integrated unit based on the IP address of the target second fire protection integrated unit.

[0076] In this embodiment, based on the IP address of the integrated fire protection unit BX, integrated fire protection unit A can establish a first TCP long connection with integrated fire protection unit BX. Integrated fire protection unit A can subsequently obtain the establishment result of the first TCP long connection.

[0077] S303, if the first TCP long connection is successfully established, send the first network subscription frame to the target second fire protection integrated machine based on the first TCP long connection.

[0078] In this embodiment, if the first TCP long connection is successfully established, the fire protection integrated unit A sends a network subscription frame (i.e., the first network subscription frame) to the fire protection integrated unit BX based on the first TCP long connection. The fire protection integrated unit A can subsequently obtain the sending result of the first network subscription frame, as well as the subscription response frame (i.e., the first subscription response frame) returned by the fire protection integrated unit BX in response to the first network subscription frame.

[0079] Additionally, if the first TCP long connection fails to be established, the controller number of the target second fire-fighting integrated unit is added to the TCP reconnection queue. Specifically, in this embodiment, if the first TCP long connection fails to be established (e.g., the fire-fighting integrated unit BX is not powered on or the network is disconnected), the fire-fighting integrated unit A adds the controller number of the fire-fighting integrated unit BX to the TCP reconnection queue.

[0080] S304, if the first network subscription frame is successfully sent and the first subscription response frame of the target second fire protection integrated machine is received, the first heartbeat frame is sent to the target second fire protection integrated machine at regular intervals based on the first TCP long connection.

[0081] In this embodiment, if the first network subscription frame is successfully sent and the first subscription response frame of the fire protection integrated machine BX is received, the fire protection integrated machine A sends a heartbeat frame (i.e., the first heartbeat frame) to the fire protection integrated machine BX based on the first TCP long connection. The fire protection integrated machine A can subsequently obtain the sending result of the first heartbeat frame and the heartbeat response frame (i.e., the first heartbeat response frame) returned by the fire protection integrated machine BX in response to the first heartbeat frame.

[0082] Furthermore, if the first network subscription frame fails to be sent or the first subscription response frame of the target second fire-fighting integrated machine is not received, the process returns to step S303, which involves "sending the first network subscription frame to the target second fire-fighting integrated machine based on the first TCP long connection." When the number of times the first network subscription frame is sent reaches the corresponding first upper limit, the first TCP long connection is disconnected, and the controller number of the target second fire-fighting integrated machine is added to the TCP reconnection queue. Specifically, in this embodiment, if the first network subscription frame fails to be sent or the first subscription response frame of the fire-fighting integrated machine BX is not received, the fire-fighting integrated machine A attempts to send the first network subscription frame again, returning to step S304, which involves "sending the first network subscription frame to the target second fire-fighting integrated machine based on the first TCP long connection." Simultaneously, the number of times the first network subscription frame is sent is counted. If it reaches the corresponding first upper limit (e.g., 3 times), it is considered that the first TCP long connection with the fire-fighting integrated machine BX has been disconnected. The first TCP long connection is actively disconnected, and the controller number of the fire-fighting integrated machine BX is added to the TCP reconnection queue.

[0083] S305, if the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire protection integrated machine is received, return to the execution of step S304, which is "sending the first heartbeat frame to the target second fire protection integrated machine at regular intervals based on the first TCP long connection".

[0084] In this embodiment, if the first heartbeat frame is successfully sent and a first heartbeat response frame is received from the fire-fighting integrated unit BX, the fire-fighting integrated unit A returns to step S304, "sending the first heartbeat frame to the target second fire-fighting integrated unit based on the first TCP long-term connection," thereby maintaining the first TCP long connection with the fire-fighting integrated unit BX. Of course, the fire-fighting integrated unit can also continue to traverse the controller numbers in the slave configuration to re-determine the target second fire-fighting integrated unit.

[0085] Furthermore, if the first heartbeat frame fails to be sent or the first heartbeat response frame from the target second fire-fighting integrated unit is not received, the process returns to step S304, which involves periodically sending the first heartbeat frame to the target second fire-fighting integrated unit based on the first TCP long connection. When the number of times the first heartbeat frame is sent reaches the corresponding second upper limit, the first TCP long connection is disconnected, and the controller number of the target second fire-fighting integrated unit is added to the TCP reconnection queue. Specifically, in this embodiment, if the first heartbeat frame fails to be sent or the first heartbeat response frame from the fire-fighting integrated unit BX is not received, the fire-fighting integrated unit A attempts to send the first heartbeat frame again, returning to step S306, which involves periodically sending the first heartbeat frame to the target second fire-fighting integrated unit. Simultaneously, the number of times the first heartbeat frame is sent is counted. If the number reaches the corresponding second upper limit (e.g., 3 times), it is considered that the first TCP long connection with the fire-fighting integrated unit BX has been disconnected, and the first TCP long connection is actively disconnected, and the controller number of the fire-fighting integrated unit BX is added to the TCP reconnection queue.

[0086] It should be noted that if the first heartbeat frame is successfully sent, but the first heartbeat response frame is not received multiple times in a row, it is considered that there is a deviation in the network image or the information sent by the slave device. The fire-fighting integrated machine A can report this situation to alert the subway fire-fighting personnel.

[0087] Based on this, if the host machine restarts during operation, a new TCP long connection can be established and maintained with the slave machine. In this regard, the networking method for a subway fire-fighting integrated machine provided in this application embodiment, wherein step S102 "establishing and maintaining a first transmission control protocol TCP long connection with the second fire-fighting integrated machine as a slave machine according to the slave machine configuration" may further include the following steps:

[0088] Monitor the running status of the machine; if the running status is restarted, return to step S301.

[0089] In this embodiment, the fire protection integrated machine A can monitor the operating status of the machine. If a restart, disconnection, power failure or other situation occurs, causing a restart and entering the restart state, it returns to step S301 to re-establish and maintain the first TCP long connection with the fire protection integrated machine as the slave machine.

[0090] In one possible implementation, a self-detection and reconnection mechanism can ensure a stable and accurate connection between the host and slave devices. In this regard, the networking method for a subway fire-fighting integrated machine provided in this application embodiment further includes the following steps:

[0091] The controller number in the TCP reconnection queue is periodically traversed to determine the target second fire protection integrated machine to be connected, and the process returns to step S302. If the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire protection integrated machine is received, the controller code of the target second fire protection integrated machine is deleted from the TCP reconnection queue.

[0092] In this embodiment, the fire protection integrated machine A traverses the controller numbers in the TCP reconnection queue to determine the target second fire protection integrated machine to be connected, and then returns to step S302. If the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire protection integrated machine is received, the controller code of the target second fire protection integrated machine is deleted from the TCP reconnection queue.

[0093] Furthermore, if the first long TCP connection establishment fails, the controller code of the target second fire protection integrated unit will remain in the TCP reconnection queue. If the first network subscription frame fails to be sent, or if the first subscription response frame from the target second fire protection integrated unit is not received, the process returns to step S304, "sending the first network subscription frame to the target second fire protection integrated unit based on the first long TCP connection." When the number of times the first network subscription frame is sent reaches the corresponding first upper limit, the first long TCP connection is disconnected, and the controller number of the target second fire protection integrated unit will remain in the TCP reconnection queue. If the first heartbeat frame fails, or if the first heartbeat response frame from the target second fire protection integrated unit is not received, the process returns to step S306, "sending the first heartbeat frame to the target second fire protection integrated unit based on the first long timed TCP connection." When the number of times the first heartbeat frame is sent reaches the second upper limit, the first long TCP connection is disconnected, and the controller number of the target second fire protection integrated unit will remain in the TCP reconnection queue.

[0094] S103, if the network role is slave, establish and maintain a second TCP long connection with the third fire protection integrated machine as the master; send the local working information to the third fire protection integrated machine based on the second TCP long connection. The second fire protection integrated machine and the third fire protection integrated machine are different fire protection integrated machines.

[0095] In this embodiment of the application, if the networking role of the fire protection integrated machine A is a slave machine, then the fire protection integrated machine (hereinafter referred to as fire protection integrated machine C) that subscribes to it can be used as the master machine, and a TCP long connection (i.e., the second TCP long connection) can be established and maintained with it. Based on the second TCP long connection, the working information of the machine (including the information of the machine's fire protection peripherals) is sent to the fire protection integrated machine C.

[0096] In one possible implementation, the slave device can select the master device using a whitelist. See also Figure 5 , Figure 5This is another schematic flowchart illustrating a networking method for an integrated subway fire suppression system provided in this application embodiment. (See attached diagram.) Figure 5 As shown in the embodiment of this application, a networking method for an integrated fire-fighting machine in a subway is provided. In step S103, "establishing and maintaining a second TCP long connection with the third integrated fire-fighting machine as the host" can include steps S401 to S403. These steps are described in detail below.

[0097] S401: If a second network subscription frame is received from the third fire protection integrated unit based on the second TCP long connection, the host whitelist of the local machine is retrieved.

[0098] In this embodiment, subway firefighters can configure a host whitelist for the integrated fire protection unit A according to the actual scenario. The whitelist can contain the controller number of the host. If the integrated fire protection unit A receives a network subscription frame (i.e., the second network subscription frame) sent by the integrated fire protection unit C based on the second TCP long connection, it will retrieve its own host whitelist.

[0099] S402, if the third fire protection integrated unit is in the host whitelist, send a second subscription response frame to the third fire protection integrated unit based on the second TCP long connection.

[0100] In this embodiment of the application, if the controller number of the fire protection integrated machine C is in the host whitelist, the fire protection integrated machine A sends a subscription response frame (i.e., the second subscription response frame) to the fire protection integrated machine C based on the second TCP long connection.

[0101] S403: If a second heartbeat frame is received from the third fire protection integrated unit based on the second TCP long connection, a second heartbeat response frame is sent to the third fire protection integrated unit based on the second TCP long connection.

[0102] In this embodiment of the application, if the fire protection integrated machine A receives a heartbeat frame (i.e., the second heartbeat frame) sent by the fire protection integrated machine C based on the second TCP long connection, then the fire protection integrated machine A sends a heartbeat response frame (i.e., the second heartbeat response frame) to the fire protection integrated machine C based on the second TCP long connection.

[0103] Based on the above description, the networking method for an integrated subway fire suppression system provided in this application embodiment achieves networking between integrated fire suppression systems via TCP long connections through master-slave networking configuration, realizing the purpose of rapid networking and improving the convenience and stability of the networking function of the subway fire suppression system. Furthermore, the networking function can be directly configured through a human-machine interface, which is simple, easy to use, and easy to modify for subway fire suppression personnel. In addition, the self-detection and reconnection mechanism ensures the stability and accuracy of the connection between the master and slave devices.

If the first heartbeat frame is successfully sent and the first heartbeat response frame of the target second fire protection unit is received, the controller code of the target second fire protection unit is deleted from the TCP reconnection queue.
