Problems solved by technology

Triggering this type of protection usually requires the corresponding stress to exceed a certain range for a certain period of time. It has a good protective effect against slowly changing stress, but it cannot cope with rapidly changing stress, such as impact stress caused by falling or impact. In some cases, the steering gear is often damaged before the protective measures of the machine are activated.

Embodiment 1

[0137] Figure 4 A schematic diagram of Embodiment 1 of the present invention is shown.

[0138] Such as Figure 4 As shown, Z is an obstacle, which can be a wall or other objects, and the displacement direction of the robot is shown by the arrow. The angle a is the range value of the included angle of the machine along the displacement direction. Among them, the machine runs in the displacement direction of the arrow. If the speed is too fast, it is easy to directly contact obstacles, which may cause damage to the steering gear on the feet. It can be seen from the figure that when the machine moves along the displacement direction, the two feet within the angle range a may first touch the obstacle, which may cause damage. Therefore, it is necessary to avoid such a situation. First, obtain the displacement direction of the machine, which can be obtained according to the sensors in the machine. By obtaining the displacement direction, it can be judged that the steering gear...

Embodiment 2

[0140] Figure 5 A schematic diagram of Embodiment 2 of the present invention is shown.

[0141] Such as Figure 5 As shown, the machine will tilt when going down the steps. If the step difference is large, the machine may cause the risk of rollover or falling when going down the steps. Therefore, it is also necessary to judge the tilt angle of the machine. First, obtain the angle between the current position of the machine and the horizontal plane, which is the first angle b2; and record the first angle value. Then, the angle between the machine and the horizontal plane before the preset time is obtained, which is the second angle b1. After obtaining the first included angle b2 and the second included angle b1, calculate the difference between the first included angle and the second included angle to obtain the included angle difference, where the difference can be an absolute difference, expressed as a positive number form. It is judged whether the included angle differ...

Abstract

A steering gear protection method, system and readable storage medium for a machine, wherein the method includes: acquiring a current state value of the machine; calculating a rate of change of the current state value; judging whether the rate of change of the state value exceeds a preset value Change rate threshold; if the change rate threshold is exceeded, the operating state of the steering gear will be changed. The present invention controls the steering gear in advance by judging the running state value of the machine, thereby reducing the possibility of damage to the steering gear. And in the specific control, the displacement and speed are judged, which can better avoid the damage rate of the steering gear when it falls or collides with obstacles.

Description

technical field [0001] The present invention relates to the field of sensor detection, and more specifically, relates to a steering gear protection method, system and readable storage medium of a machine. Background technique [0002] The steering gear is a position (angle) servo drive, suitable for those control systems that require constant changes in angle and can be maintained. The steering gear is mainly suitable for those control systems that require constant changes in angle and can be maintained, such as the arms and legs of humanoid robots, and the direction control of car models and aircraft models. The control signal of the steering gear is actually a pulse width modulation signal (PWM signal), which can be generated by FPGA devices, analog circuits or single-chip microcomputers. At present, it also includes the bus steering gear, which communicates with the steering gear in the form of data, and obtains the current position of the steering gear and the position ...
