Description

Technical Field

[0001] The invention relates to the technical field of parking lots, and in particular to an intelligent parking lot system based on an omnidirectional self-propelled mobile platform of Mecanum wheels. Background Art

[0002] The car is an important symbol of modern industrial civilization. Since the emergence of a large number of motor vehicles in China in the 1980s, my country has determined the macroeconomic policy for the development of the automobile industry. By the end of 2020, China's motor vehicle ownership will reach 372 million. Among them, there are 281 million cars; there are 456 million motor vehicle drivers, of which 418 million are car drivers. With the development of my country's economic level, the improvement of national income level and the continuous decline of car prices, the number of urban motor vehicles continues to rise, the demand for parking in cities is also increasing, and the contradiction and problems of supply and demand in the construction and use of parking lots are becoming increasingly prominent. Due to the early construction and certain design defects of traditional parking lots, the number of parking spaces cannot meet the demand for vehicle growth, and the entrances and exits usually cause congestion, resulting in the phenomenon of "difficult parking" in cities. In order to solve the problem of urban parking, there are three methods to choose from: one is to upgrade the parking lot to be intelligent; expand the scale of the parking lot; the second is to improve the utilization rate of parking facilities. my country's major and medium-sized cities generally choose to expand the scale of parking lots. However, due to the shortage of urban land resources, expanding the scale of parking lots must be a gradual and slow process. How to use limited space resources to the greatest extent possible to meet parking needs has become an urgent problem to be solved. The common problems in parking facilities and management are:

[0003] (1) As the size of parking lots gradually expands, car owners are unable to find vacant parking spaces quickly after entering the parking lot; they tend to drive in circles, which not only occupies the small parking space, but also causes congestion and wastes a lot of car owners’ time.

[0004] (2) The number of remaining parking spaces in a parking lot cannot be counted and requires manual survey. In addition, the parking lot does not have a function to guide car owners to find their cars. In large parking lots with multiple sections, it is difficult for car owners to find their cars in a timely manner.

[0005] (3) In order to facilitate parking for car owners, parking lots have high floor heights, wide routes, and large vacant parking spaces, resulting in low parking lot utilization and efficiency. To this end, we propose an intelligent parking system based on an omnidirectional self-propelled mobile platform with Mecanum wheels. Summary of the invention

[0006] The purpose of the present invention is to solve the problems mentioned in the above background technology. The present invention provides an intelligent parking system based on an omnidirectional self-propelled mobile platform of Mecanum wheels.

[0016] Furthermore, the monitoring camera is a high-definition camera.

[0017] Furthermore, the wireless communication module is connected to the monitoring camera and the operating host via a network signal.

[0018] Furthermore, the intelligent parking system comprises the following steps:

[0019] Step 1: At the entrance of the parking lot, the car owner only needs to park the car in the designated parking space at the entrance. When the monitoring camera at the entrance of the parking lot detects a vehicle that needs to park, the omnidirectional self-propelled mobile platform will automatically go to the entrance. At this time, the car owner can leave the car and go to the destination by himself, and the omnidirectional self-propelled mobile platform interacts with the smart car to be parked through wireless communication;

[0020] Step 2: There are running conveyor belts at the entrance parking area and on the slope, which can automatically park the vehicle on the support platform, and the pressure sensor detects whether the vehicle has completely entered the platform to avoid misjudgment;

[0021] Step three, the omnidirectional self-propelled mobile platform will then intelligently move to the parking space according to the path planning program, complete the parking operation, communicate with the parking space, record the parking information, and then return to the charging area or park the next car.

DETAILED DESCRIPTION

[0028] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1 - Figure 3 The present invention provides an intelligent parking system based on an omnidirectional self-propelled mobile platform of Mecanum wheels, comprising:

[0030] The omnidirectional self-propelled mobile platform 1 includes a frame 101, a battery 102 installed inside the upper end of the frame 101, Mecanum wheels 103 installed at the four corners of the side walls of the frame 101, an encoding motor 104 installed inside the Mecanum wheels 103, a Bluetooth communication module 105 installed on the front and back of the frame 101, pressure sensors 106 installed at the four corners of the upper end of the frame 101, a support platform 107 installed on the upper end of the pressure sensor 106, and a ramp 108 installed on the rear side of the support platform 107.

[0031] The frame 101 can support the components, the battery 102 can provide power support for the encoding motor 104, the encoding motor 104 can rotate the Mecanum wheel 103, and the Bluetooth communication module 105 can communicate. The Bluetooth communication module 105 can exchange information with the communication module 203 on the parking space to confirm whether there is a vehicle in the parking space, thereby confirming an empty parking space. The pressure sensor 106 can monitor the weight of the support platform 107 in real time to detect whether the vehicle has stopped at the upper end of the support platform 107, so that the vehicle can be parked in the empty parking space through the omnidirectional self-propelled mobile platform 1. The support platform 107 can support the vehicle, and the slope 108 can move the vehicle to the top of the support platform 107.

[0032] The intelligent parking system 2 includes a monitoring camera 201 arranged at the entrance and exit of the parking lot, a wireless communication module 202 and a communication module 203 installed on the parking space.

[0033] The monitoring camera 201 can detect whether there is a vehicle that needs to be parked, the wireless communication module 202 can achieve the purpose of uploading video information, and the communication module 203 can interact with the Bluetooth communication module 105, so that the omnidirectional self-propelled mobile platform 1 can interact with the smart car to be parked through wireless communication, with a high degree of automation.

[0034] In this embodiment, preferably, the frame 101 has a built-in operating host electrically connected to the encoder motor 104, and the operating host is connected to the pressure sensor 106 via a network signal; under the action of the operating host, the encoder motor 104 can work and the data parameters monitored by the pressure sensor 106 can also be received.

[0035] In this embodiment, preferably, the Mecanum wheel 103 is a two-piece type, and the Mecanum wheel 103 is transmission-connected to the encoding motor 104, and each encoding motor 104 is equipped with a controller; under the action of the controller, each Mecanum wheel 103 can work in steps, and under the action of the encoding motor 104, the rotation of the Mecanum wheel 103 can be realized.

[0036] In this embodiment, preferably, each Mecanum wheel 103 has four running directions of forward, backward, left and right, which can achieve the purpose of movement in different directions. The omnidirectional self-propelled mobile platform 1 rotates in situ by running the Mecanum wheels 103 on both sides in opposite directions. The reverse rotation is closest to the in-situ rotation. This is because the rotation center of the omnidirectional self-propelled mobile platform 1 is on the axle at this time. When the speeds of the two Mecanum wheels 103 are equal and opposite, the rotation center of the omnidirectional self-propelled mobile platform 1 is exactly at the center of the axle, realizing the in-situ rotation of the center on the axle. Under the same circumstances, this rotation method has the shortest rotation time, relatively faster speed, higher efficiency, and can ensure the safety of the platform. It passes through the small curve of the parking lot at the fastest speed and the smallest rotation radius. When there are multiple vehicles at the intersection When a vehicle is to be parked, the parking efficiency of a single platform will inevitably not be able to meet the needs; at this time, multiple mobile platforms are required to work simultaneously, and the joint operation of multiple omnidirectional self-propelled mobile platforms 1 involves group coupled motion path planning. When two omnidirectional self-propelled mobile platforms 1 meet, it can be solved by installing a microwave radar or an ultrasonic sensor at the front end of the omnidirectional self-propelled mobile platform 1 and using a conventional obstacle avoidance program; for the queuing problem of multiple omnidirectional self-propelled mobile platforms 1, route expansion and path planning are carried out according to actual conditions, and the entry and exit routes are separated to ensure that the routes in the parking lot can complete the path planning of a single-direction circular closed loop, and this path method is written to each omnidirectional self-propelled mobile platform 1 in the form of an algorithm program, and the shortest path algorithm can be introduced later on this basis, which can not only solve the queuing problem of multiple platforms but also improve the efficiency of coupled operations.

[0037] In this embodiment, preferably, the Bluetooth communication module 105 is connected to the terminal device via a network; under the action of the Bluetooth communication module 105, the purpose of transmitting the location information can be achieved.

[0038] In this embodiment, preferably, the support platform 107 is made of steel plates by stamping; the manufacturing process is simple.

[0039] In this embodiment, preferably, the monitoring camera 201 uses a high-definition camera, which can ensure the quality of video acquisition.

[0040] In this embodiment, preferably, the wireless communication module 202 is connected to the monitoring camera 201 and the operating host via a network signal; the video information monitored by the monitoring camera 201 can be uploaded to the operating host through the wireless communication module 202, thereby enabling the omnidirectional self-propelled mobile platform 1 to move.

[0041] The working principle and use process of the present invention:

[0042] Step 1: At the entrance of the parking lot, the car owner only needs to park the car in the designated parking space at the entrance. When the monitoring camera 201 at the entrance of the parking lot detects that there is a vehicle that needs to park, the omnidirectional self-propelled mobile platform 1 will automatically go to the entrance. At this time, the car owner can leave the car and go to the destination by himself, and the omnidirectional self-propelled mobile platform 1 interacts with the smart car to be parked through wireless communication;
