The second microprocessor 21 is used as the main control chip of the train detector 2 for data storage and processing. The second remote radio frequency unit 22 is interactively connected with the second microprocessor 21 by signals.

The first long-distance radio frequency unit 12 and the second long-distance radio frequency unit 22 all select the 2.4GHz wireless radio frequency chip with a maximum communication distance of 50-70 meters, equipped with a special peripheral circuit, and use it as long-distance data cascading transmission; The radio frequency unit 13 selects a 2.4GHz wireless radio frequency chip with a maximum communication distance of 0.5-2 meters, and is equipped with a special peripheral circuit for short-distance sensing.

The first microprocessor 11 and the second microprocessor 21 are interactively connected through the first remote radio frequency unit 12 and the second remote radio frequency unit 22 .

An automatic sensing method of an electronic induction device for unhooking and hanging operations of railway vehicles, as shown in Figure 2, the method installs a train detector 2 on each locomotive JC, and installs an electronic detector 2 at both ends of the locomotive JC and the vehicle CP. Sensor 1. The vehicle detector 2 on the locomotive JC communicates with the electronic sensors 1 at both ends of the locomotive JC through long-distance point-to-point transmission, and the adjacent locomotive JC and the vehicle CP and the electronic sensors 1 between the adjacent vehicle CP and the vehicle CP The short-distance perception communicates, and the electronic sensors 1 at both ends of the CP of the same vehicle communicate through long-distance point-to-point transmission.

Two adjacent electronic sensors 1 (essentially refers to the first microprocessor 11 of the electronic sensor 1, which is omitted for the convenience of description, the same below) transmit data through the short-distance radio frequency unit 13, and the two remote Data is transmitted between the electronic sensors 1 through the first remote radio frequency unit 12, and the format of the data includes a hooking information packet and a roll call information packet. The electronic sensor 1 stores the ID number of the locomotive JC or vehicle CP where it is located. The electronic sensor 1 perceives and judges whether there is an adjacent electronic sensor 1 through the short-range radio frequency unit 13, and judges whether two adjacent locomotives JC or vehicle CP are in the hooked state. The electronic sensor 1 senses and judges whether there is an adjacent electronic sensor 1 every T1 time through the short-range radio frequency unit 13, and if it exists, the ID number of the locomotive JC or the vehicle CP where the adjacent electronic sensor 1 is located and its own location The ID number of the locomotive JC or the vehicle CP is written into the self-hitching information packet, and if it does not exist, only the ID number of the locomotive JC or the vehicle CP where it is located is written into the self-hitching information packet. The two electronic sensors 1 at both ends of the same locomotive JC or vehicle CP respectively check whether the communication link is normal or not through the first remote radio frequency unit 12 point-to-point every T2 time.

The train detector 2 located in the locomotive JC initiates the transmission process of the roll call information packet, and the electronic sensor 1 that receives the roll call information packet transmits the hang information packet stored by itself and the received roll call information packet forwarded by other electronic sensors 1. Then the information packet is fed back to the train detector 2. The train detector 2 analyzes and processes the hitch information packets received by roll call, and obtains dynamic information such as the quantity, ID number, sequence, etc. of locomotives JC or vehicle CPs attached to the train.

As shown in Figure 3, train detector 2 sends roll call information packet to the electronic sensor 101 of locomotive JC tail end point-to-point every T3 time by second long-distance radio frequency unit 22 and first long-distance radio frequency unit 12, and locomotive JC tail end After electronic sensor 101 receives roll call information packet, by the first long-distance radio frequency unit 12 and the second long-distance radio frequency unit 22, self mount information packet is fed back to train detector 2, simultaneously by short-distance radio frequency unit 13 will roll call The information packet is forwarded to the electronic sensor 102 at the head end of the first adjacent vehicle CP1, and other mounted information packets received by the short-range radio frequency unit 13 are forwarded by the first long-distance radio frequency unit 12 and the second long-distance radio frequency unit 22 Give train detector 2.

The second remote radio frequency unit 22 forwards it to the train detector 2 .

After the electronic sensor 103 at the tail end of the first adjacent vehicle CP1 receives the roll call information packet, it feeds back the self-hooking information packet to the electronic sensor 102 at the head end of the first adjacent vehicle CP1 through the first remote radio frequency unit 12, and simultaneously passes The short-range radio frequency unit 13 forwards the roll call information packet to the electronic sensor 104 at the head end of the second adjacent vehicle CP2, and forwards other information packets received by the short-range radio frequency unit 13 to the The electronic sensor 102 at the head end of the first adjacent vehicle CP1, the electronic sensor 102 at the head end of the first adjacent vehicle CP1 is forwarded to the electronic sensor 101 at the tail end of the locomotive JC through the short-distance radio frequency unit 13, and then the electronic sensor 101 at the tail end of the locomotive JC The device 101 forwards to the train detector 2 through the first long-range radio frequency unit 12 and the second long-distance radio frequency unit 22.

By analogy, until the electronic sensor of the last vehicle CPn in the train receives the roll call information packet, and feeds back its own mount information packet to the train detector 2 through the above steps, a roll call process is completed.

The train detector 2 sequentially forms a queue with the articulated information packets received each time, forming a set of train information, and calculates the final train articulated information queue based on the repeated parts of the train information formed by multiple roll calls.

It can be seen from the above that the transmission direction of the roll call information packet and the hook information packet is just opposite.

Note: For a certain electronic sensor 1, the above-mentioned "self-mounted information package" refers to the articulated information of the vehicle where it is stored in the first microprocessor 11 of the electronic sensor 1, " "Other articulated information package" refers to the articulated information of other vehicles stored in the first microprocessor 11 of other electronic sensors 1 far away from the electronic sensor 1 .
