Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, specifically to a signal enhancement control device for a locomotive wireless remote control. Background Technology

[0002] The locomotive wireless remote controller is a device designed for remotely controlling locomotives in high-risk, high-temperature, and high-dust areas during shunting operations. However, when shunting operations are carried out in areas with strong magnetic fields, high temperatures, conductive dust, high-risk areas such as toxic environments, and water hazard risks, the complex on-site working environment can easily lead to signal loss, signal interference, and signal shielding. This can cause intermittent loss or delay of the remote control signal for shunting operations, which can significantly impact the remote control driving of the locomotive and the overall efficiency of shunting operations.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, a signal enhancement control device for a locomotive wireless remote controller includes a locomotive 4, a control host 2 connected to the locomotive 4, an F8L10D module 7 bidirectionally connected to the control host 2, a wireless controller 8 connected to the F8L10D module 7, and the wireless controller 8 and the control host 2 are electrically connected.

[0017] The control host 2 is connected to the locomotive equipment information module 1.

[0018] The F8L10D module 7 is connected to the remote control 6.

[0019] The control host 2 is connected to the F8L10D module 7 via RS232 connection cable 5.

[0020] An F8L10D processing data stream 3 is installed between the control host 2 and the locomotive 4.

[0021] In practical application, the operation process of the locomotive 4 wireless remote controller 6 signal device mainly includes three aspects: communication transmission, command parsing, and execution. In communication transmission, control commands are transmitted from the remote control device to the locomotive 4 via radio communication technology. In command parsing, the control host 2 on the locomotive 4 is responsible for parsing the received command signals and converting them into executable control commands. The control host 2 typically consists of a microprocessor, sensors, and actuators. The microprocessor is responsible for command parsing and control command generation. Sensors are used to collect locomotive status information, such as speed and steering. Actuators are responsible for executing control commands, such as driving the motor and braking. By parsing the received commands and combining them with the locomotive 4's status information, the system can generate corresponding control commands. During execution, the actuators on locomotive 4 execute the parsed control commands. The actuators are used to control the power system and motion state of locomotive 4. When the control equipment sends a command to accelerate locomotive 4, the parsing system generates a corresponding control command and then adjusts the output of the power system through the actuators to control the acceleration of locomotive 4. When a braking command is sent, the parsing system generates a corresponding control command and applies control force to the braking system through the actuators to achieve braking of locomotive 4.

[0022] This device amplifies the transmitted signal by adding a Four-Faith Communication F8L10D7 N LoRa module, providing wireless data transmission functionality to users via the LoRa network. The internal structure of the remote control 6 is optimized by isolating the F8L10D7 N LoRa module from the voice module, control chip, and other components within a dedicated shielded enclosure, thereby enhancing the wireless remote control signal and preventing signal loss. The embedded wireless data transmission module, utilizing LoRa spread spectrum technology, along with electronic filtering programs and integrated chips, can independently filter and shield invalid electromagnetic and interference signals, increasing the transmission power and distance of the wireless signal. Simultaneously, it effectively isolates and filters external and internal electromagnetic and analog signals, preventing interference with the effective transmission of the remote control signal.

[0023] The control host 2 of locomotive 4 transmits the data sent by the remote controller 6 to the LoRa terminal via the RS232 connection line 5. The LoRa terminal then aggregates the data to the LoRa relay unit, which finally transmits the data to the control host 2 via a 4G signal. The control host 2 then issues control commands to remotely operate locomotive 4. In the basic process of spread spectrum communication, the baseband data signal is processed by spread spectrum modulation to become a data signal with a wider radio frequency band. The power density of the signal decreases. The despreading and demodulation process involves down-converting and despreading the signal in the radio frequency band to restore it to the original baseband data. In response to broadband interference, where the original interference source completely covers the effective signal across the entire frequency band, after despreading, the interference signal becomes flat noise, while the effective signal becomes a narrowband signal. Furthermore, the signal strength within the effective bandwidth is significantly greater than the interference signal, allowing for demodulation of the effective signal. This enables technicians to perform remote maintenance without being physically present at the project site. LoRa modulation technology performs unique spectrum widening processing on the signal, achieving a receiving sensitivity of -148dBm. Forward error correction technology, combined with channel conflict detection optimization, solves the problem of concurrent packet loss at actual nodes. Automatic packet transmission of multiple data effectively ensures the integrity of data packets without loss, thereby enhancing the remote control signal and preventing signal loss. This significantly increases the wireless signal transmission power and distance of locomotive 4. Simultaneously, it effectively isolates and filters external and internal electromagnetic simulation signals, preventing interference with the effective transmission of the remote control signal and ensuring the smooth operation of shunting operations on railway locomotive 4. Therefore, this device has excellent practicality.
