Motor control method based on the motion curve of the parking lever

Abstract

The invention relates to a motor control method based on a parking rod movement curve. A parking rod direct-current servo motor and a stop board direct-current servo motor rotate according to the motion equation of y=a*bt+c*arctan(d*t), impact caused by sudden stop and sudden start of the motors on the motors and mechanical devices is prevented, and the service life is prolonged. Meanwhile, the motors rotate for calibration when idle, so that the control is more accurate and safer.

Description

technical field [0001] The invention belongs to the field of automatic control, especially the field of motor control. Background technique [0002] At present, in the management of residential or public parking lots, it is usually to set up a parking sign pole at the entrance and exit of the parking lot, and configure a parking management kiosk supplemented by an administrator for the management and charging of vehicles in and out of the parking lot. In some of the parking lots, vehicle identification devices, such as cameras, can be used to identify the license plate information of vehicles entering and leaving the parking lot, and then the relevant vehicle entry and exit information, including license plates and entry time, can be synchronized to the parking management system. In the traditional parking management system, when the free parking space in the parking lot is greater than 0, the vehicles waiting at the entrance can enter the venue, and the parking sign pole at...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing stop signs / parking poles rise and fall at a constant speed, which will cause a large impact on the motor when starting and stopping, and if the movement is too slow, it will affect the traffic efficiency

[0005] 2. The traditional parking management system has certain loopholes in the management of vacant parking spaces in the parking lot, which limits the efficiency of the use of parking spaces

On the other hand, some temporary vehicles entering and exiting the parking lot, such as taxis, do not need to be parked. If identification and vehicle counting are performed at the gate, such temporary vehicles will also reduce the number of parking spaces in the system (actually not Occupying the parking space), and when the parking space is 0, such temporary vehicles are not allowed to enter, which will affect the traffic efficiency

That is to say, the traditional vehicle management system cannot effectively manage the vehicles in this scene, and even affect the entry and exit of such vehicles because there are no parking spaces.

[0006] 3. The traditional parking management system cannot realize the effective sharing of parking spaces

On the other hand, some fixed parking spaces are not equipped with relevant control devices, and the parking spaces are occupied by other vehicles. When the vehicle of the owner of the parking space needs to stop, because the fixed parking space is occupied, it is often necessary to contact relevant personnel and wait for a long time to move the car. Processing etc.

[0007] 4. Although some parking spaces are equipped with card swiping devices to ensure the user's fixed parking space, but its security is not enough, the card is lost or cracked will lead to the occupation of the user's parking space

However, for parking spaces in open public locations such as roadsides, since there is no closed entrance and exit, entrance and exit management cannot be carried out. At present, it mainly relies on parking fee administrators for manual management
