They cover two core scenarios: the construction phase and the operation phase. The core objective is to solve problems such as geological risks, imbalance of environmental parameters, and chaotic traffic order in tunnels through real-time monitoring, intelligent adjustment, and emergency response.

[0003] Although this traditional method has a simple system design, simple system architecture, and convenient data acquisition and control, it cannot meet the higher intelligent requirements of tunnel electromechanical control, and cannot unify and integrate the control of systems such as lighting, ventilation, traffic, and environment. Summary of the Invention

[0007] As a preferred embodiment of the present invention: the regional host is a server in the MQTT protocol, and the edge executor is a client in the MQTT protocol.

[0008] As a preferred embodiment of the present invention: the edge actuator consists of an edge host and several extended actuators. The edge host and the extended actuators communicate with each other via a CAN bus. The edge host is the communication master module of the edge actuator.

[0009] As a preferred embodiment of the present invention, the mobile terminal communicates with the edge actuator via Bluetooth.

[0010] As a preferred embodiment of the present invention, the edge actuator can be externally connected to a human-machine interface screen and communicate via RS232.

[0011] As a preferred embodiment of the present invention: the control strategy module is responsible for customizing automatic or manual control strategies and execution requirements, the control execution module is responsible for generating specific control instructions from the control strategies, and the control communication module is responsible for sending the control instructions to the edge execution machine.

[0012] As a preferred embodiment of the present invention: the edge actuator has a control data processing priority defined by the edge host, the mobile terminal control has a higher priority than the control customized by the edge host from the regional host, and the edge actuator human-machine interface control has a higher priority than the mobile terminal control.

[0013] As a preferred embodiment of the present invention: the data processing priority defined within the regional host prioritizes manual control over automatic control.

[0014] Compared with the prior art, the beneficial effects of the present invention are: on the one hand, it is necessary to unify and integrate the control of systems such as lighting, ventilation, traffic, and environment; on the other hand, it is necessary to combine automatic control with manual control, and remote control with mobile terminal control. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the framework of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1 This invention provides a technical solution: a modular and multi-protocol integrated tunnel area control data communication method, including a tunnel area control system, which comprises an area host, an edge actuator, and a mobile terminal, characterized by the following steps: S1. Complete the communication connection between the regional host and the edge execution unit; S2. Modular design of control strategy, control execution and control communication is completed within the regional host; S3. The edge actuator subscribes to control commands issued by the regional host communication module from the edge host and then issues the commands to specific extended actuators for execution. S4. The edge actuator collects data information from each port of the extended actuator according to preset requirements by the edge host, and after processing the data at the edge, pushes it to the regional host communication module.

[0018] Specifically, the connection between the regional host and the edge actuator is achieved through an Ethernet redundant ring network. Data communication between the regional host and the edge actuator adopts the MQTT protocol, with the regional host acting as the server and the edge actuator as the client. The edge actuator consists of an edge host and several extended actuators. Data communication between the edge host and the extended actuators is conducted via a CAN bus. The edge host is the main communication module of the edge actuator. The mobile device communicates with the edge actuator via Bluetooth. The edge actuator can also be connected to a human-machine interface (HMI) via RS232. The control strategy module is responsible for customizing automatic or manual control strategies and execution requirements. The control execution module is responsible for generating specific control commands from the control strategies. The control communication module is responsible for sending control commands to the edge actuator. The edge actuator has a control data processing priority defined by the edge host. The mobile device control has a higher priority than the control customized by the edge host from the regional host. The edge actuator HMI control has a higher priority than the mobile device control.

[0019] Furthermore, the data processing priority defined within the regional host prioritizes manual control over automatic control.

[0020] Specifically, in use, the control strategy, control execution, and control communication are modularly designed within the regional host. The control strategy module is responsible for customizing automatic or manual control strategies and execution requirements; the control execution module is responsible for generating specific control commands from the control strategies; and the control communication module is responsible for sending control commands to the edge actuators. Due to the independence of internal data flow, expanding new controlled peripherals and customizing new control strategies does not affect existing services. Then, during control execution, the edge actuators subscribe to the control commands sent by the regional host communication module from the edge host and send the commands to the specific extended actuators for execution. During data collection, the edge actuators collect data information from each port of the extended actuators according to preset requirements from the edge host, process it at the edge, and then push it to the regional host communication module.

[0021] Throughout the process, the data processing priorities defined within the regional host are as follows: manual control has a higher priority than automatic control; the control data processing priorities defined by the edge host for the edge actuators are as follows: mobile terminal control has a higher priority than the control customized by the edge host from the regional host; and the human-machine interface control of the edge actuators has a higher priority than mobile terminal control.

[0022] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
