[0008] The display module is used for displaying brake information;

[0009] The power supply module is used for power supply;

[0010] The information processing module is used for collecting and processing information of the wheels;

[0011] The brake module is used for braking the wheels;

[0012] The alarm module is used for giving an alarm when a brake failure occurs;

[0013] The emergency module is used for emergency braking;

[0014] The brake module includes a base box, on the top of which two flipping rods are rotatably installed. Friction mechanisms are arranged on both flipping rods, and a wheel hub is arranged between the two friction mechanisms. An oil pumping pressure mechanism is arranged in the base box. The oil pumping pressure mechanism is connected with an adjusting plate, and the adjusting plate is slidably installed in the base box. Springs are installed on the bottom inner walls of the base box, and the springs are connected with the bottom of the adjusting plate. Two push plates are slidably installed on the top of the adjusting plate. Transmission plates are slidably installed on both push plates. A push groove is formed at the bottom of the transmission plate, and the push plate is slidably connected with the inner wall of the push groove. A compression spring is installed on the top of the push plate, and a pressure sensor is installed between the compression spring and the push groove.

[0015] Preferably, the information processing module includes wheel speed acquisition, wheel temperature acquisition and brake pressure information acquisition. Both wheel speed acquisition and wheel temperature acquisition include sensors. The sensors are arranged on the top of the base box and below the wheel hub, and are used for acquiring the speed and temperature of the wheel hub. The brake pressure information acquisition is carried out through the pressure sensor.

[0016] Preferably, the emergency module includes wheel speed limitation, brake pressure limitation and brake interval time limitation.

[0017] Preferably, the friction mechanism includes an arc-shaped plate, which is installed on the top of the flipping rod. Brake pads are installed on the inner side of the arc-shaped plate, and the brake pads are in contact with the outer side of the wheel hub.

[0018] Preferably, the oil pumping pressure mechanism includes an oil cylinder, an oil pump and an oil tank. The oil cylinder, the oil pump and the oil tank are all arranged on the top inner wall of the base box. The oil cylinder, the oil pump and the oil tank are communicated through pipelines. The output shaft of the oil cylinder is connected with the top of the adjusting plate.

[0019] Preferably, two strip-shaped holes are formed on the top of the base box, and the transmission plate is slidably connected with the inner walls of the strip-shaped holes.

[0020] Preferably, an adjustment groove is formed in the top of the adjustment plate, an adjustment block is slidably installed in the adjustment groove, the adjustment block is connected to the bottom of the push plate, a limiting rod is fixedly installed in the adjustment groove, and the adjustment block is slidably installed outside the limiting rod.

[0021] Preferably, a plurality of guide rods are fixedly installed in the base box, and the adjustment plate is slidably installed outside the plurality of guide rods.

[0022] An intelligent electric control braking control method for a pumping unit includes the following steps:

[0023] S1: When not in use and the vehicle power supply is cut off, a spring provides elastic force for the adjustment plate, so that the adjustment plate pushes the push plate upward. The push plate provides elastic force for the force transmission plate through the compression spring and the pressure sensor, so that the force transmission plate pushes the arc plate to flip. A flipping force is provided for the arc plate through the flipping rod, and the arc plate drives the brake pads to brake the wheel hub. When the power is disconnected, the wheel hub can be braked;

[0024] S2: When the power is turned on, the oil pump sends the oil in the fuel tank into the oil cylinder. The oil cylinder pushes the adjustment plate downward, the adjustment plate drives the two push plates downward, the push plate drives the arc plate to flip through the force transmission plate, and the arc plate drives the brake pads to leave the wheel hub, so that the brake fixation can be released;

[0025] S3: When braking, the oil pump starts in reverse, so that the oil cylinder starts in reverse and drives the adjustment plate upward, so that the arc plate drives the brake pads to apply pressure to the wheel hub for braking. The pressure can be sensed through the pressure sensor, and the wheel hub can be locked;

[0026] S4: When emergency braking is required or the vehicle speed needs to be controlled, the sensor senses the rotation speed and temperature of the wheel hub, sets the rotation speed of the wheel hub. When the rotation speed of the wheel hub is too high, the arc plate drives the brake pads to squeeze and fix the wheel hub, and the rotation speed of the wheel hub can be intelligently reduced. The pressure can be sensed through the pressure sensor.

[0027] In the present invention, the beneficial effects of the intelligent electric control braking system and control method for a pumping unit are as follows:

[0028] When this solution is not in use, a spring provides elastic force for the adjusting plate, causing the adjusting plate to push the push plate upward. The push plate provides elastic force for the force transmission plate through a compression spring and a pressure sensor, causing the force transmission plate to push the arc plate to flip. A flipping rod provides the flipping force for the arc plate. The arc plate drives the brake pads to brake the wheel hub, enabling braking of the wheel hub when the power is disconnected. When the power is connected, the oil pump sends the oil in the fuel tank into the oil cylinder. The oil cylinder pushes the adjusting plate downward. The adjusting plate drives the two push plates downward. The push plate drives the arc plate to flip through the force transmission plate, and the arc plate drives the brake pads away from the wheel hub, releasing the brake fixation;

[0029] When this solution brakes, the oil pump starts in reverse, causing the oil cylinder to start in reverse and drive the adjusting plate upward, causing the arc plate to drive the brake pads to apply pressure and brake the wheel hub. The pressure can be sensed through the pressure sensor, and the wheel hub can be locked;

[0030] When this solution needs emergency braking or needs to control the vehicle speed, the sensor senses the rotation speed and temperature of the wheel hub, sets the rotation speed of the wheel hub. When the rotation speed of the wheel hub is too high, the arc plate drives the brake pads to squeeze and fix the wheel hub, which can intelligently reduce the rotation speed of the wheel hub. The pressure can be sensed through the pressure sensor;

[0031] The present invention can intelligently control the wheel hub to brake, can automatically brake after power-off, and can monitor the movement of the wheel hub at all times. BRIEF DESCRIPTION OF THE DRAWINGS
