Problems solved by technology

Therefore, when multiple LoRa modules send and receive data together, there will be message blocking, resulting in data loss or delay, and reducing work efficiency
For example: now there are two remote controllers and four code sending blocks, when one remote controller sends a message, the other five devices (another remote controller and four code sending blocks) will receive the message; one remote controller and One code sending block can also form a group, and there are also interference problems in the case of multiple groups. When two remote controllers send commands together and four code sending blocks reply to messages, the amount of data in the channel will increase exponentially. Cause mutual interference, message blocking
At present, this problem is mainly solved by assigning time slot communication on demand, but this method has the problem of low efficiency

specific Embodiment 1

[0052] according to Figures 1 to 2 As shown, the present invention provides a working method of a wireless locomotive signal code sending system. The present invention provides a multi-group wireless locomotive signal code sending system. The system includes a remote controller and a code sending block group. The code block groups communicate through touch and wireless communication, and the code sending blocks among the code sending block groups communicate through touch communication.

[0053] The remote controller includes a first control module, a first NFC module and a first LoRa module; the first control module is respectively connected to the first NFC module and the first LoRa module; the code sending block group includes the first code sending block And the second code sending block, the first code sending block includes a second control module, a second NFC module and a second LoRa module, and the second control module is connected to the second NFC module and the s...

specific Embodiment 2

[0065] The difference between the second embodiment of the present invention and the first embodiment is that the step 10 is specifically: turn on the remote controller and the code sending block group of the first group of wireless locomotive signal code sending system through the respective buttons, and the remote controller and code sending The control module between the block groups controls all NFC modules for point-to-point communication, and controls their respective LoRa modules for master-slave communication;

[0066] The LoRa module used includes 83 communication channels, and the channel numbers range from 1 to 83. The working channel of the code sending block in the code sending block group defaults to the maximum channel number 83 of the LoRa module; for example, the device number of the first group of remote control 1 is KJYKQ1018 , then its default LoRa module working channel calculation formula is: 1018 / (83-1)=12mode 34, that is, the default number of the LoRa m...

specific Embodiment 3

[0069] The difference between the third embodiment of the present application and the first embodiment is that the step 20 is specifically: when the default working channel of the LoRa module of the remote controller is the same, and there are multiple sets of wireless locomotive signal sending systems, the wireless communication signal of the LoRa module When working at the same time within the coverage area, the control module of the remote controller that goes online later receives the data information sent by the LoRa module of the remaining group of remote controllers through the LoRa module within the default working channel and the set time. At this time, the default working channel of the Loara module is blocked. Occupied, after going online, the control module of the remote controller needs to update the equipment work list and control the sound and light alarm module and the display screen to remind the operator that there is a remote controller currently working on th...

Abstract

An operation method of a wireless locomotive signal code sending system, a wireless locomotive signal code sending system, a code sending block and a remote controller. The invention relates to the technical field of multi-group locomotive code transmitter communication, which determines whether the default working channel of the remote controller is occupied, switches the working channel of the remote controller, and determines the final working channel; the remote controller and the code sending block are networked through NFC, Switch the working channel of the LoRa module of the code sending block to the same as the working channel of the LoRa module of the remote control; remote control the code sending block through the final working channel of the remote control, and set the working mode of the remote control. Through the short-distance communication module, any remote control and code sending block can be networked to improve the accuracy of networking and the timeliness of communication within the network. When within the coverage of communication signals, different working channels are used between groups as transmission channels for business data. Only the remote controllers and code sending blocks in the group communicate with each other, which avoids interference between signals and reduces the time spent during work. channel pressure.

Description

technical field [0001] The invention relates to the technical field of multi-group locomotive signal code transmitter communication, and relates to an operation method of a wireless locomotive signal code transmitter system, a wireless locomotive signal code transmitter system, a code transmitter block and a remote controller. Background technique [0002] At present, according to the relevant railway regulations, on-board function testing of locomotive signaling equipment is required in the links of entry and exit, temporary repair, level I repair, level II repair, and level III repair. When the rail where the locomotive is located does not have the track circuit signal transmission conditions, the operator needs to use a portable code sending block or a code sending stick to send the track circuit signal to the receiving coil to detect the locomotive signal on-board equipment. [0003] The code transmitting rod includes two transmitting antennas, which can be placed on the...
