Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like figure 1 In this intelligent control method of train motion based on wireless sensor network, we adopt the independent drive of the body part, rely on the wireless sensor network composed of wireless communication units to form a small local area network, and realize the realization through information communication. Coordinated control of the body, at the same time, the distance between the cars is collected through the sensor unit of the car, real-time monitoring, and real-time adjustment of the action state through data analysis, so as to avoid the traditional dragging method. The body cannot be controlled freely and the body is too long. Dangerous situation occurs.

[0029] The zigbee-based wireless sensor applied in the wireless communication unit is to embed the zigbee module in the wireless sensor network into each carriage and head of...

Abstract

The invention discloses a wireless sensor network based intelligent control method for movement of a train set, and belongs to the field of application and automatic control of embedded Internet of things. The whole train set is divided into a train head part and a compartment part, wherein the train head part comprises a central control unit, a wireless communication unit and a sensor unit; the wireless communication unit uses a zigbee network; the compartment part comprises compartment central control units, compartment wireless communication units, compartment motor control units and compartment sensor units; the compartment wireless communication units use zigbee networks to transmit data to the compartment central control units; motors rotate to realize the movement of compartments; and ultrasonic sensors in the compartment sensor units are used for acquiring distances between two compartments and feeding back the distances to the compartment central control units to adjust the movement of the compartments in real time, so as to ensure the compartments are at stable positions in the train set. By the wireless sensor network based intelligent control method for the movement of the train set, the transportation capability of the train set is improved, the cost is reduced, and the flexibility and safety of the transportation environment are increased.

Description

technical field [0001] The intelligent control of train movement based on wireless sensor network is a new type of vehicle motion control concept with wireless control, automatic avoidance and road memory functions. It combines wireless communication function, positioning function and sensor monitoring function. with automatic control field. Background technique [0002] This intelligent control method is aimed at the field of train transportation which is composed of a locomotive and multiple carriages and is used for the transportation of large materials. The applied technologies include: wireless sensor network technology, zigbee wireless automatic networking technology and sensor technology. [0003] Wireless Sensor Networks (WSN, Wireless Sensor Networks) is a wireless self-organizing network composed of a group of densely arranged and randomly scattered sensors, whose purpose is to cooperatively sense, collect and process the information of the sensed objects in the g...
