Intelligent monitoring system for vehicle parking

Technical Field

The utility model discloses an intelligent monitoring system for vehicle berthing, the intelligence in mainly used city parks. The system is applied to a modularized intelligent three-dimensional parking device, provides guarantee for normal operation of a garage, and belongs to the technical field of intelligent garages and intelligent parking.

Background

With the continuous progress of human society and the continuous development of scientific technology, the production and living modes of human beings tend to be concentrated, the scale of cities is larger and larger, the living space of people in the cities is smaller and smaller, and therefore the concept of urban space is fully utilized and applied to some fields of urban development, such as three-dimensional buildings, three-dimensional traffic, three-dimensional warehouses, three-dimensional parking garages and the like. Except for taxies, the motor vehicles generally run on the road 10% -20% of the time and stop for 80% -90%, so that a large amount of space needs to be provided for parking the motor vehicles, and the parking difficulty often becomes the main burden of urban traffic. Therefore, the "parking" problem is not negligible throughout the entire traffic. Particularly, in city centers, in busy places such as businesses, restaurants and the like, the population density is high, the number of vehicles is large, the empty space is small, and residential districts with dense high buildings are more 'full of vehicles' and cause worried problems that motor vehicles occupy public roads and green places and occupy living spaces. The cars are continuously increased, the problem of difficult urban parking is increasingly prominent, the smooth urban traffic and urban landscape are influenced, and the urban greening and beautifying are destroyed. The contradiction between the increase of the number of automobiles and the shortage of parking spaces is increasingly prominent, the problem of difficult parking almost covers the cities of large and small nationwide, and the problem of increasingly prominent difficult parking in China at present is generated. And vehicle intelligent monitoring system berths just can cooperate the problem that intelligent garage further solved the difficulty of parkking, can park more vehicles in limited space to convenient construction.

SUMMERY OF THE UTILITY MODEL

The utility model provides a module, intelligent vehicle berths intelligent monitoring system, and the accessible of matching with module stereo garage acquires the initial position that the vehicle put in storage, through route planning, stops the vehicle to the selected parking stall of user fast, has saved the parking time.

The utility model discloses a technical means as follows:

an intelligent monitoring system for vehicle parking matched with an intelligent garage comprises an upper computer, an upper computer control program, a lower computer control program and hardware controlled by the lower computer. The hardware comprises a single chip microcomputer, a photoelectric sensor, a stepping motor driving plate, a wireless transmission module and the like, and is shown in the attached figure 1. The intelligent monitoring system for vehicle parking receives the position information of the garage transmitted by the photoelectric sensor through the single chip microcomputer, is combined with the target position information transmitted by the upper computer, is operated by the control program of the lower computer to complete path planning, transmits the path information to the stepping motor, controls the stepping motor to rotate to execute corresponding actions, and simultaneously transmits the garage information to the upper computer through the wireless transmission module to monitor the vehicle parking condition in real time.

And the singlechip is directly connected with the driving plate. The drive plate selects a 2-phase 4-wire drive plate, and a stepping motor is connected with the drive plate. The stepping motor is more than 65W. The photoelectric sensing range of the photoelectric sensor is 50cm-60 cm.

The sending frequency of the wireless transmission module is divided into low frequency 300MHz and high frequency 800MHz, which are used for communication between the upper computer and the lower computer and can be switched between high frequency and low frequency to prevent errors of data in the transmission process.

The lower computer control program mainly plays a role in monitoring control and logic operation. The method mainly comprises the step of placing the vehicle plate information in an n multiplied by n matrix, wherein the matrix is matched with a modular garage, so that an empty vehicle position exists in the matrix and is represented by 0, and the rest positions are provided with vehicle plates and are represented by 1. The logic operation can also realize that the program can jump out immediately when entering the dead loop and search layer by using recursive call until finding the path meeting the condition.

(3) Path planning

a. Since there are many cases of path planning, some of which are unnecessary to execute and time consuming, these useless program branches need to be subtracted, i.e., "pruned", to improve the execution efficiency of the program;

b. when the program is subjected to repeated judgment, in order to prevent the program from entering a dead loop due to the mismeasurement of the sensor, a backtracking statement is added at the end of the program to make the program exit to try the next direction;

c. completing a backtracking statement through recursive calling;

d. if the instruction in the next direction is not found from the backtracking to the starting point, the backtracking is continuously executed, the program returns to the starting point of the previous program through recursive calling, and the judgment is carried out until the instruction in the next direction is found;

e. the motor is numbered and the number information is assigned to the array at the current position so as to find the next direction as the information of the vehicle plate where the vehicle is located needs to be remembered when the path planning is carried out;

f. when the program judges branches for multiple times, when the information of the vehicle plate is superposed with the information of the selected parking space, the searching is finished, and the program calculates according to the depth of the information, so that the deep searching is called;

g. the optimization of the program can be used for wide search, parallel operation is carried out, and multiple paths are planned together, so that the parking time can be prolonged.
