One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are only schematic illustrations of the present disclosure, in which the same reference numerals denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The locomotive wireless debugging equipment provided by the embodiment of the disclosure is described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a locomotive connection in a related art communication using a hard wire connection.

As shown in fig. 1, an automatic gearbox control unit (Transmission Control Unit, TCU) for implementing locomotive traction control is disposed in a main converter 11, the main converter 11 is disposed in a machinery room of a locomotive, a notebook computer (industrial personal computer) 12 for sending a debugging function command is disposed in a cab, in order to send control command data to the TCU in the main converter 11 through the notebook computer end 12 and receive locomotive data (including working condition data of the locomotive), when the functions of locomotive debugging, factory line normal line test operation, locomotive data analysis, signal state looking at on-line variable, downloading data, fault clearing and the like are required to be performed, communication connection is performed through a special hard line, wire connection cannot penetrate a wall, is influenced by an obstacle such as a mechanical door, and the door between the locomotive machinery needs to be opened, so that during the functions of locomotive debugging, factory line normal line test operation, locomotive data analysis, signal state looking at on-line variable at different stages, downloading data, fault clearing and the like, the special hard line can be disturbed, signals are not stable, and the special hard line is limited by the operation space length of the special hard line is limited. Meanwhile, when the locomotive is in a static high-pressure and test-running process, the locomotive body jolts, and operators have high risk of falling injury, electric shock and the like among the machines. In short, the operating environment is poor, the experience is poor, and the security is not high.

Furthermore, maintenance tasks of the harmonious series locomotive are gradually increased year by year, but the method and equipment for debugging the locomotive still use a special hard wire connection mode for communication, and the special hard wire is inconvenient to coil and carry and is easily influenced by folding, abnormal extrusion, cable aging and the like, so that when the special hard wire is used, the stability of signal and equipment performance is poor, and the maintenance is inconvenient. Meanwhile, the special hard wire communication technology is used, and abnormal conditions such as tripping of people, damage to equipment plugs, equipment being brought to the ground by wires and the like can occur frequently. Therefore, providing a wireless debugging device and method is an urgent need for the development of locomotive technology from the standpoint of locomotive maintenance efficiency and convenience, both from the standpoint of solving the drawbacks of prior locomotive communication and optimizing the communication mode of the debugging test of the lifting locomotive.

In the related art, a notebook computer (a computer for debugging) is connected with a TCU chassis or a RIOM chassis through a DB9 plug and a socket of an RS232 protocol. When the wireless connection between the notebook computer and the TCU case or RIOM case is required, the RS232 level signal of the notebook computer needs to be converted, data transmission is performed through a wireless transmission master module (the notebook computer side), and then the converted transistor-transistor logic integrated circuit (Transistor Transistor Logic, TTL) level signal is converted into the RS232 level again through a wireless transmission slave module (the TCU case or RIOM case side).

In some possible embodiments, the radio frequency scheme with the main stream of 400MHz (megahertz) has the advantages of long transmission distance, no configuration and easy implementation. However, in the process of locomotive debugging, electromagnetic signal interference is serious, and the interphone for test-run group connection and the locomotive wireless dispatching communication equipment work in the frequency band, so that the scheme has defects.

In some embodiments, the wireless transparent transmission method may include a bluetooth (bluetooth)/WIFI (wireless fidelity) scheme in a 2.4G (gigahertz) mode and a 433MHz wireless radio frequency scheme, where the 2.4GHz transmission scheme has the advantages that the transmission signal is stable and is not easy to be interfered, and the interference signal generated by each device in the locomotive is not substantially in the frequency band. The wireless transparent transmission method has the advantages of low power consumption and mature scheme.

Based on the technical problem, the embodiment of the disclosure provides locomotive wireless debugging equipment, which adopts a Bluetooth BLE5 remote serial port transparent transmission technology, overcomes the problem that poor contact is caused by cable connection damage or interface stress, generates data packet loss, and avoids noise radiation and electric shock risk that a mechanical door cannot be closed during high-voltage operation. Meanwhile, the wireless debugging equipment for the locomotive has the advantages of being small and portable, free of carrying data cables in boarding operation and the like.
