Description

Technical Field

[0001] The present application relates to the technical field of automatic car washing, and in particular to a brush control method and system, tunnel-type car washing equipment and storage medium. Background Art

[0002] Due to the development of the automobile industry, most families own more than one car for transportation. Therefore, the car washing industry that emerged in response to the automobile industry has also flourished.

[0003] Car wash machines are divided into tunnel type and gantry type. In order to provide users with a better car washing experience, tunnel type car wash machines now provide users with a wider driving channel. This results in a larger area for the brush to travel in the tunnel type car wash machine.

Too deep a brush eating may cause damage to the vehicle, while too shallow a brush eating may result in poor cleaning effect. Summary of the Invention

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, a process, method, terminal, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. In the claims, specification and drawings of this application, relational terms such as "first" and "second" are merely used to distinguish one entity / operation / object from another entity / operation / object, and do not necessarily require or imply any actual relationship or order between these entities / operations / objects.

[0056] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0057] Please refer to Figure 1 , which is a schematic diagram of the brush holding device provided in an embodiment of the present application.

[0058] The holding brush includes a mounting frame 100, including two holding brush units 200 arranged side by side on the mounting frame 100 along a first horizontal direction, the holding brush unit 200 includes a lever 201 mounted on the mounting frame 100 and rotating around a vertical axis, and a brush 202 arranged on the lever 201, and the brush 202 can be switched between a working state and a non-working state by the rotation of the lever 201; the cylinder 300 is arranged on the mounting frame 100 and is connected to the lever 201 for controlling the rotation of the lever 201. When both sides of the vehicle need to be cleaned, the vehicle is moved along a second horizontal direction perpendicular to the first horizontal direction to the cleaning area between the two brushes 202, and then cleaning liquid is sprayed on the vehicle. After that, the control mechanism 300 controls the lever arm 201 to rotate around the corresponding vertical axis, and the lever arm 201 can drive the corresponding brush 202 to move around the vertical axis. When the two brushes 202 move to fit the two side walls of the vehicle, the brushes 202 are in a working state. After that, when the vehicle is moved, or the holding brushes are moved, or both the vehicle and the holding brushes are moved, the brushes 202 can gradually scrub both sides of the vehicle. When the scrubbing is completed, the lever arm 201 drives the brushes 202 to separate from the two side walls of the vehicle, and the brushes 202 are in a non-working state. Finally, the vehicle is moved out of the cleaning area to complete the cleaning of both sides of the vehicle.

[0060] Step S101: Initially set the upper and lower limits of the brush-holding cylinder. Specifically, testing has shown that the cylinder pressure corresponds to the contact depth between the brush and the vehicle. The greater the cylinder pressure, the deeper the contact depth.

[0063] Step S104: If the first real-time pressure value is greater than the preset upper limit value, the cylinder pressure is released.

[0064] Step S105: If the first real-time pressure value is less than the preset lower limit, increase the cylinder pressure.

[0065] In a practically feasible embodiment, the preset upper limit value and the preset lower limit value of the brush holding cylinder are automatically adjusted according to a number of real-time pressure values ​​at every preset interval.

[0066] In a practically feasible embodiment, when the first real-time pressure value is greater than a first preset abnormal pressure value or when the first real-time pressure value is less than a second preset abnormal pressure value, the brush is controlled to return to an initial position.

[0068] Step 201: Obtain the real-time rotation angle value of the holding brush. Specifically, by setting an angle sensor on the rotating shaft 101, the real-time rotation angle value of the holding brush is obtained.

[0069] Step 202: Obtain a preset pressure value corresponding to the real-time rotation angle value. Specifically, obtain appropriate preset pressure values ​​corresponding to several rotation angle values ​​through testing.

[0070] Step 203: Acquire a second real-time pressure value of the brush holding cylinder in real time.

[0071] Step 204: Determine the difference between the second real-time pressure value and the preset pressure value.

[0072] Step 205: If the second real-time pressure value is less than the preset pressure value, increase the cylinder pressure.

[0073] Step 206: If the second real-time pressure value is greater than the preset pressure value, release the cylinder pressure.
