[0011] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0012] like Figure 1 and Figure 2 As shown, the railway inspection sign remote safety remote control system includes: a radio remote control unit 10 and a two-way self-locking control unit 20. The radio remote control unit 10 includes a remote controller 11 for sending instructions and a receiver 12 for receiving instructions. The two-way self-locking control unit 20 includes a control mainboard 21, a control circuit 22 and a drive circuit 23. The control mainboard 21 is used to organically integrate the control circuit 22 and the drive circuit 23 to coordinate the collaborative work of each part. The control circuit 22 is used to formulate operation instructions and logical decisions. The drive circuit 23 is used to convert the instructions of the control circuit 22 into specific actions, and is connected to a swing mechanism 30. The swing mechanism 30 receives the remote control signal to realize the erection and laying down of the inspection sign.

[0013] It should be noted that the remote controller 11 is a part for the user to control the device. Usually, it is a handheld device that sends out control commands through wireless signals after pressing buttons. Inside the remote controller 11, signals are emitted through radio waves or infrared rays, where the radio waves are usually radio frequency (RF). The control main board 21 is a complete platform integrating a control circuit 22, a drive circuit 23, and other peripheral circuits. It is the core part of the entire device, responsible for coordinating the work of each module. The control main board 21 usually includes a central processing unit, a storage unit, an interface circuit, a sensor module, a drive circuit 23, a display, and an input interface, etc. The control circuit 22 is mainly responsible for directing and managing the operation of the system to ensure that each component operates according to the predetermined logic and timing. It usually includes the processing of input signals, the monitoring of states, and the output of control commands. The control circuit 22 plays the role of the brain in many electronic systems and is usually composed of a microcontroller (MCU), digital logic circuits, timing circuits, etc. Its functions are as follows: Input signal acquisition and processing: The control circuit 22 receives signals input by sensors, such as temperature, pressure, position, etc., and performs operations such as processing, amplification, and filtering on them; Logic control: According to the input signals, the control circuit 22 decides how to operate the device, usually based on preset control algorithms, such as PID control, switching quantity control, etc.; Output control signals: The control circuit 22 sends control commands to the drive circuit 23 or other execution units, instructing them to perform certain operations, such as starting a reduction motor, heating, changing the current, etc. The drive circuit 23 is responsible for driving the actual actuators to work according to the signals output by the control circuit 22, such as reduction motors, LED lights, heaters, etc. The main function of the drive circuit 23 is to convert low-power control signals into signals capable of controlling high-power loads. Its functions are as follows: Power amplification: The drive circuit 23 amplifies low-voltage and low-current control signals so as to be able to drive larger-power loads; Signal conversion: According to needs, the drive circuit 23 can convert digital signals into analog signals, or convert analog signals into digital signals to control different types of actuators; Protection function: The drive circuit 23 usually has functions such as overcurrent, overvoltage, and short-circuit protection to prevent the actuators from being damaged.

[0014] Specifically, the control circuit 22 includes: a microcontroller (MCU) or a microprocessor (MPU): serving as the control core, responsible for the execution of instructions and the decision-making of control logic; an integrated circuit (IC): used for logical operations, timing control, or signal conversion; a sensor and an input module: collecting external signals or user instructions. The drive circuit 23 includes: transistor drive: using transistors to amplify signals, such as MOSFET or BJT. Relay drive: using relays or solid-state relays to control high-power devices. Reduction motor drive: The drive circuit 23 of the motor usually involves an H-bridge circuit for controlling the rotation direction and speed of the reduction motor.

[0015] As Figure 1 shown, the remote control 11 includes two wireless remote control transmission modules 111, and the two wireless remote control transmission modules 111 are used to send control signals.

[0016] Specifically, when the user inputs control instructions through the buttons of the remote control 11, the two wireless remote control transmission modules 111 will transmit these signals to the receiver 12 via radio waves (such as radio frequency RF). Since it is "two-way" control, each channel corresponds to an independent signal.

[0017] As Figure 1 shown, the receiver 12 includes two wireless remote control reception modules 121, and the two wireless remote control reception modules 121 are used to receive signals and perform corresponding control operations.

[0018] Specifically, after receiving the wireless signal, the receiver 12 determines the actions to be performed according to the signal content. The two wireless remote control reception modules 121 can control two independent devices or perform two different operations.

[0019] As Figure 1 shown, the two-way self-locking control unit 20 further includes a battery pack 24, and the battery pack 24 is used to provide electrical energy for the control main board 21, the control circuit 22, and the drive circuit 23.

[0020] It should be noted that the battery pack 24 has a function of displaying the charge and discharge power.

[0021] As Figure 2 shown, the swing mechanism 30 includes a reduction motor 31 and a protective box 34. The output end of the reduction motor 31 is fixedly connected to a rocker arm 32. One end of the rocker arm 32 away from the reduction motor 31 is fixedly connected to a spring clip 33. The receiver 12, the two-way self-locking control unit 20, and the reduction motor 31 are all installed inside the protective box 34. The rocker arm 32 penetrates one side of the protective box 34, and a pot magnet 35 is fixedly installed outside the protective box 34.

[0022] It should be noted that the reduction motor 31 stands beside the railway line through a tripod. The reduction motor 31 controls the rotation of the rocker arm 32. The rotation of the rocker arm 32 can drive the spring clip 33 connected thereto to rotate together, so as to drive the check board or the light-shielding sheet fixedly clamped by the spring clip 33 to be erected or laid down, enabling the driver to see or not see. When the spring clip 33 is separated from the check board, the volume can be reduced, which is convenient for the safety personnel to carry to the site. After arriving at the site, the safety personnel can replace it with different check boards or light sheets according to the usage scenario for assembly and use.

[0023] Specifically, the spring clip 33 assembly can clamp the check board or the light-shielding sheet. The check board is printed with safety warnings or test numbers, and can be quickly replaced by the clamping and fixing method of the spring clip 33.

[0024] Three pot magnets 35 are installed at the bottom of the protective box 34 as the magnetic suction seats of the device. (The reason for using three pot magnets 35 is that the device needs to be adsorbed and fixed on railway equipment, but the adsorption surface of the railway equipment is not necessarily flat, and three-point support can ensure stable adsorption.) The device can be temporarily adsorbed on the railway signal machine or railway equipment through the magnetic suction seats for inspection and defense.

[0025] Meanwhile, fixing holes for connecting with the tripod are reserved at the bottom of the device for connecting with the tripod. After the device is installed and fixed on the tripod, it can stand beside the railway line or railway equipment for inspection and defense.

[0026] The reduction motor 31 drives the check board or the light-shielding sheet to be erected or laid down through the rocker arm 32 and the spring clip 33. When the check board is replaced with the light-shielding sheet, the device is adsorbed and placed on the side edge or upper edge of the shunting signal light shield. When the rocker arm 32 is vertical, the shunting signal light can be blocked by the light-shielding sheet, changing the color of the shunting signal light, and used to test the emergency response ability of the locomotive driver to observe and operate the locomotive.

[0027] One spring clip 33 can clamp check boards with different shapes or printed with different information, flexibly coping with different inspection tasks and scenarios.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
