TECHNICAL FIELD
[0001] The present application relates to the technical field of mine safety monitoring and control, and particularly relates to a system and method for realizing real-time communication between a cross-platform mobile terminal and a non-coal mine substation through a TCP Socket protocol. BACKGROUND
[0002] A non-coal mine safety monitoring system is usually composed of multiple substations and monitoring sensors, and transmits monitoring data to a ground monitoring center through a wired or wireless network to realize real-time monitoring and alarm of mine gas concentration, temperature and humidity, equipment running state and other parameters. However, the existing system generally relies on a special industrial computer or a Windows platform client and does not have mobile features, which has the following defects: Poor terminal adaptability: different platforms need to be developed respectively, and the Android and ios version codes cannot be reused, resulting in high maintenance cost.
[0003] Insufficient mobility: the inspection personnel cannot directly view data or remotely control equipment in the underground, and the data transmission delay is large.
[0004] Poor network adaptability: the network delay in the mining area is high, the packet loss rate is large, the traditional TCP connection is easy to be interrupted under network jitter, and lacks a reconnection and retransmission mechanism.
[0005] Insufficient security protection: the communication data between the existing mine substation and the client is mostly transmitted in plaintext, lacks strong authentication mechanism, and has the risk of being stolen or tampered.
[0006] Therefore, a cross-platform, mobile, weak network adaptive and high security mine substation communication solution is needed. SUMMARY

[0008] To solve the above problems, the present application provides a non-coal mine substation real-time communication system based on a cross-platform mobile terminal, which comprises a cross-platform mobile terminal communication module, a substation communication protocol adaptation module and a weak network environment optimization module.

The substation communication protocol adaptation module is connected with the cross-platform mobile terminal communication module, and is used for parsing the received binary data into service data and generating a sending frame conforming to a protocol format; The weak network environment optimization module is connected with the substation communication protocol adaptation module, and is used for heartbeat detection, automatic reconnection of disconnection and cache and retransmission on the sending frame of the substation communication protocol adaptation module.
[0009] In order to reduce the repeated development cost and reduce the maintenance cost, the cross-platform mobile terminal communication module adopts a ReactNative framework, integrates a TCP Socket communication library, and is adapted to Android and iOS platforms.
[0010] In order to be able to dynamically identify different types of sensor data, the substation communication protocol adaptation module has a hierarchical adaptive data frame splitting module, which can dynamically adjust the data frame size according to the network condition.
[0011] In order to prevent illegal access and consume substation resources, the substation communication protocol adaptation module has a two-way authentication and dynamic key negotiation module, which completes identity verification through challenge response when first connected, and uses a temporary key and an AEAD algorithm for encrypted transmission in a session.
[0012] In order to improve the safety response speed, the substation communication protocol adaptation module has a closed-loop control confirmation module, which requires the non-coal mine substation to return an execution confirmation message to update the mobile terminal state after the execution of the control instruction.
[0013] In order to improve the adaptability of weak networks, the heartbeat detection detects the connection activity by periodically sending short packets, the automatic reconnection detects the disconnection of the connection, and uses an exponential backoff strategy to try to reconnect, and the cache and retransmission cache the data that has not been sent during network interruption, and retransmits in batches after the network recovers.

The format of the received data is Figure 3 The mobile terminal parses the received data, judges whether the data transmission is completed through the packetNo field and the status bit, if not, it continues to send the data fragments to the substation according to the response, and the cycle continues until it is judged that the data transmission is completed.
