Referring to fig. 1, the code cable has a flat shape and a plurality of pairs of wires inside, according to a certain arrangement
The coding rules are that the pairs of wires cross at different positions, and the pairs of wires are overlapped together and encapsulated in a neoprene pressed sheath. The coded cable is installed along the track of the moving locomotive, the terminal of the coded cable adds a matching resistor to each pair of lines, and the starting end is connected to the central control room by a round cable. Any pair of wires in the coded cable is equivalent to a single coil. The induction antenna is two groups of coils, one group of the induction antenna is used as a sending coil, and the other group of the induction antenna is used as a receiving coil, and the two groups of the induction antenna resonate at corresponding frequencies respectively. The two sets of coils are housed in a rectangular plastic box called an induction antenna box. The antenna box is installed on a moving locomotive and is connected with a control cabinet on the locomotive by a round cable. The antenna box moves along with the movement of the locomotive and keeps a distance of 5-20cm with the coding cable all the time.
When the antenna box is close to the coding cable, the single-turn coil formed by each pair of lines in the coding cable and the coil in the antenna box mutually induce signals, so that a communication signal channel is formed between the antenna box and the coding cable (namely between the moving locomotive and the central control room). When signal current is added to the sending coil, because each pair of lines in the coding cable are crossed according to a certain coding rule, corresponding induced electromotive force can be generated from each pair of lines of the coding cable, and information reflecting the position of the sending coil in the antenna box can be obtained by detecting the phase and the amplitude of the induced electromotive force.
The length A of the antenna box is 2-3 times of the width B of the coding cable, and when the antenna box moves along the x direction along with the moving locomotive, the antenna box always covers the coding cable along the y direction. Thus, the signal S received by a pair of wires in the encoded cable is a function S = f (x, z) of the antenna box position x, z.
When the distance z between the sending coil and the coding cable is small (5-20 cm), the magnetic lines generated by the sending coil can be approximately vertical, and the magnetic lines can also be approximately uniformly distributed in the coding cable.
And information is transmitted through 5-20cm short-distance electromagnetic coupling between the antenna box arranged on the moving locomotive and the flat cable laid beside the ground track. The induction wireless data communication has a wireless communication distance of only 5-20cm, so that the flexibility of locomotive movement can be ensured, the reliability of communication quality is ensured, and the defects of wired communication and wireless communication are overcome.
Serial data sent by the moving locomotive is sent from a sending coil through modulation, is received by a coding cable communication pair wire in an induction mode and is sent to a central control room; serial data sent from the central control room is modulated and sent from the coded cable, and is inductively received by the receiving coil and sent to the moving locomotive. The co-channel interference in the industrial field cannot be filtered by band-pass filtering, and the co-channel interference must be suppressed to ensure the communication quality.
The system mainly comprises three parts, namely a central control room part, a locomotive part and a coded cable part.

The locomotive part has the functions of commanding the locomotive to work according to the received command sent by the central control room and sending the collected locomotive working state information to the central control room.
The induction antenna box is arranged on the locomotive and close to the coding cable, and the induction antenna box walks along with the locomotive and is always close to the coding cable arranged beside the locomotive track (the distance is about 5-10 cm) in the whole walking process, so that electromagnetic induction is formed between the induction antenna box and the coding cable. An induction antenna box sends out signals sent by the machine control cabinet, and the same signals are generated in the coding cable through electromagnetic induction; the two coding cables send signals to the central control cabinet, and the same signals are generated at the induction antenna through electromagnetic induction.
The machine control cabinet has the function of collecting the condition of the vehicle and transmitting the condition to the main control computer through data communication; and controlling the locomotive according to the command of the main control computer.
The display screen and the voice device are communicated with the main control computer by adopting an RS-485 communication interface, receive information of the main control computer, and guide the operation of an operator by digital tube display and voice prompt.
The locomotive control system comprises buttons and knobs on a locomotive operating console, wherein a locomotive operator sends signals through the operating buttons, and system control is changed through the operating knobs.
The locomotive control cabinet is connected with the locomotive electrical appliance, collects locomotive working state information and controls the locomotive electrical appliance.
The system comprises eight coded cables, wherein each coke pusher, coke guide, coke quenching car and coal charging car are two. The coded cable is provided with a plurality of pairs of wires which are divided into two types of communication pairs and address pairs. The communication pair lines are crossed according to a certain rule, and the address pair lines are crossed according to a Gray code rule. After being packaged by a sheath, the cable is arranged beside a locomotive track. The coding cable sheath is formed by one-time pressing of rubber-plastic synthetic materials, and has the advantages of smooth surface, no joint, no air hole and light weight. The flame-retardant anti-aging coating has the characteristics of flame retardance, aging resistance, cold resistance and high temperature resistance, is not afraid of rainwater and acid and alkali corrosion, can particularly prevent sulfur dioxide and sunlight ultraviolet rays, and can work in an environment of minus 50 ℃ to plus 100 ℃ for a long time.
And installing a locomotive control cabinet on each locomotive, wherein the locomotive control cabinet forms the collected locomotive working state information into a message and transmits the message to the central control room, and implements the command of the central control room.
The four-vehicle interlocking coking process automatic management control system automatically identifies the number of the locomotive according to the detected position of the locomotive; judging the direction of the locomotive which should run correctly according to the detected position of the locomotive and the position of the coke pushing furnace number planned; only when the main control computer gives a coke pushing permission command according to comprehensive information of all aspects and production process requirements, coke pushing can be performed; setting an interlock release switch to release the interlock when the system malfunctions; only when the main control computer gives out an order that the coke pusher is allowed to take the furnace door according to comprehensive information of all aspects and production process requirements, the coke pusher can take the furnace door; after a command that the coke guide car allows the door to be removed is given, the coke guide car can only remove the door; door-removing interlocking and interlocking-releasing selection switches are arranged on coke pushing cars and coke guide operation tables so as to facilitate the locomotive to overhaul and maintain furnace doors or release interlocking when a system has a fault; accurately judging the coke pushing start and the coke pushing end so as to record the coke pushing start and the coke pushing end time; the start and the end of coal leveling are accurately judged, so that the coal charging time is recorded, and the automatic management control work of the four-vehicle interlocking coking process is realized.
