Description
Technical Field

Background
At present, according to relevant regulations of railways, locomotive signal vehicle-mounted equipment needs to be subjected to on-vehicle function detection in the links of warehousing and warehousing, imminent repair, I-level repair, II-level repair, III-level repair and the like. When the rail at the position of the locomotive does not have the track circuit signal transmission condition, an operator needs to use the portable code transmitting block or the code transmitting rod to transmit the track circuit signal to the receiving coil to detect the locomotive signal vehicle-mounted equipment.
The code sending rod comprises two sending antennas, and the two sending antennas can send signals to the two receiving coils simultaneously when placed on the steel rail below the receiving coils, but the problems of long code sending rod and inconvenience in carrying exist.
The portable code sending block comprises a single code sending function code sending block and two wireless code sending blocks with a remote control function and a code sending function, wherein the single code sending block needs an operator to operate under a vehicle, and another operator needs to cooperate to operate, so that the safety is poor, and the manpower is increased. The latter only needs one person to remotely control the operation on the vehicle, so the wireless transmission block is the mainstream detection tool in the development direction.
In the wireless transmission block, the LoRa module is mainly used as a communication method between the remote controller and the transmission block. The communication mode of the LoRa belongs to broadcasting, that is, information of each other can be received among a plurality of LoRa modules. Therefore, when a plurality of LoRa modules transmit and receive data together, message blocking occurs, which causes data loss or delay, and reduces work efficiency. For example: now, there are two remote controllers and four transmission blocks, and when one remote controller transmits a message, the other five devices (the other remote controller and the four transmission blocks) all receive the message; when two remote controllers send instructions together and four sending blocks reply messages, the data volume in a channel is multiplied, so that mutual interference and message blocking are caused.

According to the invention, through a mode of NFC networking and switching of LoRa working channels, single-group system networking is carried out between the remote controller and the code sending block through NFC, and different LoRa working channels are switched among the groups of systems, so that the remote controller and the code sending block in the same group enter the working channels of the remote controller and the code sending block to carry out communication, thereby achieving the purposes of preventing mutual interference and improving the working efficiency.
The remote controller also comprises a first key, a display screen and a sound-light alarm module; the first control module is connected with the display screen and the acousto-optic alarm module, and the first key is in control connection with the first control module. The remote controller controls the sound-light alarm module and the display screen through the control module to prompt a user whether other groups of remote controllers with the same channel are working at present, and the user is asked to switch the LoRa working channel through the first key according to own requirements.
The first sending block further comprises a second key and a first signal generating module, the second key is in control connection with a second control module, the second control module is connected with the first signal generating module, and the first signal generating module is connected with a first locomotive signal receiving coil in a wired or wireless mode.

The number of the remote controllers and the code sending block groups is more than or equal to 1, and when the number is 1, only one group of wireless locomotive signal code sending systems works.
A method for preventing mutual interference of operation of a plurality of groups of wireless locomotive signal code sending systems comprises the following steps:
step 10: setting a point-to-point communication mode of the remote controller and the code sending block group, determining whether the remote controller and the code sending block group have a working memory mode, and acquiring a default working channel of an LoRa module in the remote controller;

The second embodiment is as follows:
the embodiment two of the present invention differs from the embodiment one only in that the step 10 specifically includes: the remote controller and the code sending block group of the first group of wireless locomotive signal code sending system are started through respective keys, and the control module between the remote controller and the code sending block group controls all NFC modules to carry out point-to-point communication and controls respective LoRa modules to carry out master-slave communication;

And the control module of the remote controller subtracts one from the total channel number of the LoRa module by using the four digits after the equipment number to obtain a remainder, and the obtained remainder is used as a default working channel of the LoRa module of the remote controller. If the first group of remote controllers and the first group of code sending block sending blocks are set to be in the memory mode after the last operation, the operator can directly execute the step 6 after the operation is started, so that a large number of operation processes can be saved, and the operation is accelerated.

If the first group of remote controllers 1 starts to work first, and detects that 34 channels do not have interference signals sent by other groups of remote controllers with the same channels through the control module, the first group of remote controllers determines that the working channel of the LoRa module is 34. The second group of remote controllers is started up later, the working channels of two remote controller LoRa modules in the equipment working list are 34 at the moment, the second group of remote controllers which are started up later can control the sound-light alarm module and the display screen through the control module to prompt a user, other groups of remote controllers with the same channels work at present, and the user is asked to switch the LoRa working channels according to own requirements.
