Description

Technical Field

[0001] This utility model belongs to the technical field of railway shunting equipment, specifically relating to a device for switching radio communication channels in railway shunting operations. Background Technology

[0002] Radio walkie-talkies are commonly used communication devices in railway shunting operations, with each locomotive equipped with a fixed communication channel. Typically, several locomotives operate simultaneously at a station, and a factory area may have multiple stations, with locomotives from different stations often working concurrently. The shift operator needs to communicate via radio with the corresponding locomotive driver and shunting operator to arrange and schedule shunting operations and to make emergency contacts in special circumstances. The shift operator frequently needs to switch between different communication channels on the shunting station in a short period of time. The existing shunting station uses two keys (+ and -) to select the communication channel, requiring multiple presses to switch between channels, resulting in slow channel switching. Utility Model Content

[0003] This utility model provides a radio communication channel switching device for railway shunting operations to solve the problem of slow radio communication channel switching in existing railway shunting operations.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a keyboard body, which is equipped with a microcontroller and multiple illuminated key switches. The microcontroller is connected to a regional control station. The multiple illuminated key switches correspond to multiple communication channels controlled by the regional control station. It also includes a matrix keyboard circuit and an LED circuit constructed from the multiple illuminated key switches. Each illuminated key switch includes a key portion and an LED light-emitting diode. The two ends of the key portion are respectively connected to two different I / O ports of the microcontroller, allowing the microcontroller to scan and identify whether the illuminated key switch has been clicked. One end of each LED light-emitting diode is connected to an I / O port of the microcontroller to control its on / off state. The other end of the LED is connected to the circuit power supply. The matrix keyboard circuit adopts a line-by-line scanning method, which can reduce the number of I / O ports occupied by the microcontroller and improve the reliability and integration of the circuit. The LED circuit controls the on / off state and color change of the LED through the I / O ports of the microcontroller to intuitively display the currently selected communication channel and the status of the previously selected communication channel. When a certain illuminated button switch is clicked, the microcontroller controls the station to switch to the corresponding communication channel, and at the same time controls the LED of the illuminated button switch to light up, and controls the LED on the previously clicked illuminated button switch to switch to another color.

[0005] A more specific technical solution to the above technical solution may be as follows: the plurality of illuminated button switches include twenty-three channel illuminated buttons and one return illuminated button. When any of the channel illuminated buttons is clicked, the microcontroller controls the district station to switch to the communication channel corresponding to that channel illuminated button, and simultaneously controls the LED light-emitting diode on that channel illuminated button to light up green, and controls the LED light-emitting diode on the previously clicked channel illuminated button to switch to bright yellow. When the return illuminated button is clicked, the microcontroller controls the LED light-emitting diodes on the two most recently clicked channel illuminated buttons to switch their light colors, i.e., the one that was originally bright green becomes bright yellow, and the one that was originally bright yellow becomes bright green, and simultaneously controls the district station to switch to the previously selected communication channel.

[0006] Furthermore, the microcontroller is connected to the district chief's station via a serial communication interface.

[0007] Furthermore, the keyboard body is a metal casing, which has good electromagnetic shielding, heat dissipation, and protective properties.

[0008] Furthermore, the keyboard body is also provided with a bracket, and the bracket has screw holes for fixing the keyboard body in a specific position.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: by corresponding the communication channels of the district chief's console with multiple illuminated key switches on the keyboard body, the communication channels of all locomotives are displayed on the illuminated key switches on the keyboard body, enabling one-click operation for quick switching of communication channels; by using the on / off state and color change of LEDs, different bright colors are used to distinguish the currently used communication channel from the previously remembered communication channel, allowing the duty officer to quickly switch between the two most recently used channels, improving communication efficiency.

At the same time, the control panel switches to the second communication channel, and controls the LED 4 on the illuminated button 2 of channel 2 to light up green and the LED 4 on the illuminated button 2 of channel 3 to light up yellow.
