Abstract

A parking and retrieval method for a multi-layer parking garage using a random spare parking space for movement, comprising a PLC and an ultrasonic sensor, the ultrasonic sensor being electrically connected to the PLC, the PLC being used for recording parking information of each parking space in the parking garage, and the ultrasonic sensor being used for detecting and sensing whether there are vehicles or obstacles in the parking garage. When a vehicle in a certain parking space needs to be moved, the PLC firstly calls stored information to obtain an empty parking space nearest to said parking space and uses the ultrasonic sensor to determine whether there is an obstacle in said nearest empty parking space and, if there is no obstacle, then said nearest empty parking space serves as a spare parking space. The present solution has the following beneficial effects: by means of the synergy of the data operations and the detection by the ultrasonic sensor, a nearby empty parking space is found as a spare parking space, thus saving space in the parking garage and reducing the vehicle-moving steps when moving a vehicle in the parking garage, which reduces the wear on the vehicle-moving mechanical equipment during operation, and realizes high efficiency in vehicle parking and retrieval.

Description

Random backup access method for three-dimensional garage

technical field

The invention relates to the field of three-dimensional parking equipment, in particular to a random backup access method for a three-dimensional garage.

Background technique

In order to achieve a higher capacity, the current intelligent storage-type three-dimensional garage usually adopts a double arrangement (that is, one car at the front and rear, a total of two cars). Usually, the car on the front side of the heavy train space is moved to the fixed reserve parking space first, and then the car on the rear side of the heavy train space is accessed. After the car access on the heavy train space is completed, it needs to Put the car on the fixed backup parking space back to its original position, and leave a spare space for the next car to be picked up and placed normally. Since the above-mentioned backup method has many action links, the efficiency of accessing the car is relatively low. Many, also led to a high failure rate of equipment.

Contents of the invention

Aiming at the above problems, the present invention proposes a random backup access method for a three-dimensional garage.

The technical scheme that the present invention takes is as follows:

A random backup access method for a three-dimensional garage, comprising a PLC and an ultrasonic sensor, the ultrasonic sensor is electrically connected to the PLC, the PLC is used to record the parking information of each parking space in the garage, and the ultrasonic sensor is used to It is used to detect whether there is a car on the sensing garage and whether there is an obstacle; when it is necessary to move a vehicle in a certain parking space, the PLC first retrieves the stored information to obtain the nearest empty parking space near the parking space, and uses the ultrasonic sensor to judge the nearest empty parking space. Check whether there are obstacles on the hole parking space, if there is no obstacle, the nearest empty parking space will be used as a spare parking space.

In this kind of random access method, when storing or retrieving a vehicle in an overlapping position, first call the information stored in the PLC, and find out whether the access parking space needs to be moved by reading the call information, and if it needs to be moved, judge and calculate The nearest vacancy and size can accommodate the parking space of the vehicle, and then use the ultrasonic sensor to detect whether there are other obstacles in the empty parking space. If there are no other obstacles, the empty parking space will be used as a spare parking space, and the rear Position The vehicle in the front row moves to the spare parking space (the spare parking space is no longer used as a spare parking space at this time). After the vehicle movement is completed, the car can be stored or picked up according to the needs. Put the car in the parking space back to its original position.

In the above method, through the synergistic effect of data calculation combined with ultrasonic sensor detection, the nearest empty parking space is searched as a spare parking space, which saves the space in the garage and reduces the steps of moving the car when moving the vehicle in the garage. The wear and tear of car machinery and equipment during work, and the efficiency of car access is high.

Optionally, a video player and a sound player are also included, and both the video player and the sound player are electrically connected to the PLC.

The function of the video player and the sound player is to send a warning message to the parker, such as the vehicle in the garage is full, or to give the parker a corresponding guide prompt message, prompting the parker to perform parking operation according to the guide information.

Optionally, when storing the car in the garage, first detect the dynamic height of the vehicle, and then perform the static height detection again after the vehicle stops at the entrance, and start the car storage operation after judging that the height of the vehicle does not exceed the height of the parking space.

The specific height measurement is realized by a photoelectric detector, which is electrically connected to the PLC. The photoelectric detector is used to monitor the height of the vehicle to ensure that the super high vehicle will not enter the parking space and avoid the vehicle height being higher than the parking space. Due to the height of the vehicle, the vehicle cannot advance into the parking space or gets stuck in the parking space.

Optionally, when storing the car in the garage, the height of the vehicle is detected first, and the car storage operation is started after judging that the height of the vehicle does not exceed the height of the parking space.

Optionally, when storing a car in the garage, it is first determined whether the position of the vehicle in the garage needs to be moved.

When there is an empty parking space directly in the garage, and the size of the parking space can accommodate the vehicle to be parked, the vehicle can be directly parked in the parking space of the hole, so that there is no need to move the car.

Optionally, when storing a car in the garage, it is first determined whether the vehicle has reached the entrance of the garage.

Optionally, when the vehicle in the garage is taken out of the garage, it is first determined whether there is a vehicle at the entrance of the garage.

Optionally, the PLC records the parking information of the vehicle after the storage or retrieval of the vehicle is completed.

Every time the car is stored or picked up, the PLC needs to record the parking information of the vehicle and update the parking information. This is to ensure the timeliness of the data in the database and make parking more convenient.

The beneficial effects of the present invention are: through the synergistic effect of data calculation combined with ultrasonic sensor detection, the nearby empty parking space is searched as a spare parking space, which saves the space in the garage and reduces the steps of moving the car when moving the vehicle in the garage. The wear and tear of the moving machinery and equipment during work is reduced, and the efficiency of car access is high.

Detailed ways:

Below in conjunction with each accompanying drawing, the present invention is described in detail.

In conjunction with accompanying drawing 1 and accompanying drawing 3, the method provided by this application is explained in detail

As shown in accompanying drawing 3, the first floor and the second floor are respectively the first floor of the three-dimensional garage in the accompanying drawing 3, and the number mark 1 is the No. 1 parking space, and the number mark 2 is the No. 2 parking space, and the number mark 3 is the No. 3 parking space, assuming this When there is a car at the entrance of the garage that needs to be parked in the No. 1 parking space, if the parking spaces on the first floor are the same size, then only the vehicle in the No. The vehicle is directly transported to the No. 2 parking space, that is, the handling process is completed, but if the size of the No. 1 parking space is different from that of the No. 2 parking space, the No. 1 parking space is large (for a relatively large car), and the No. 2 parking space is small (for a relatively large car). Smaller car), if the vehicle at the entrance of the garage is a relatively large car, in order to move the vehicle at the entrance of the garage to the No. 1 parking space, the car in the No. 2 parking space needs to be moved to the spare parking space. At this time, it is necessary to call the information stored in the PLC, and look at the empty parking space closest to the No. 1 parking space (the empty parking space needs to be able to accommodate a small car), and the information stored in the PLC shows that the nearest parking space to the No. 1 parking space is No. 3 on the 2nd floor. Parking space, at this time, the carrier installed in the garage removes the car on the No. 1 parking space, and moves to the No. 3 parking space with the car. When it reaches the vicinity of the No. 3 parking space, the ultrasonic sensor installed on the carrier will further monitor Whether there is any obstacle in the No. 3 parking space (including the vehicle, because the PLC may have the probability of making an error in recording data), if there is no obstacle, then park the car directly on the No. 3 parking space, and then the elevator runs, and the carrier on the elevator Arrive at the entrance of the garage and move the vehicle board that needs to be parked to the No. 1 parking space on the first floor. After the parking is completed, the entire car storage process is completed. If there is an obstacle in the No. 3 parking space, the staff will be informed to remove the obstacle. (i.e. exception handling), after the parking is completed, the corresponding parking information is recorded and stored, so that the information stored in the PLC can be updated in real time.

The above-mentioned parking process is further described in conjunction with accompanying drawing 1, at first when the parker parks the vehicle at the entrance, the photoelectric detector 1 first detects the height of the vehicle (the detection process can be checked by accompanying drawing 5 and accompanying drawing 6), in accompanying drawing 5 is When the vehicle enters the garage entrance, the photoelectric detector is used to measure the dynamic height of the vehicle. Accompanying drawing 6 is the static height measurement of the vehicle at the garage entrance, and the light eye 2 is used to monitor whether the vehicle is stopped and aligned in place. If find to exceed the height of this garage parking space during detection process, then send alarm prompt (being the abnormal processing in the accompanying drawing 1) immediately by video player and sound player, remind the driver that can't park his vehicle here. When the driver's vehicle is a small car that can be parked in the No. 3 parking space, the carrier can directly transport it to the No. 3 parking space for parking. During the process of parking in the No. The parking space is detected to determine whether there is an obstacle in the No. 3 parking space. If there is an obstacle, the staff will be notified immediately to remove the obstacle (ie, abnormal processing).

The parking process is further described in conjunction with accompanying drawing 1. If there is an empty parking space of matching size in the garage when the car is at the entrance, the carrier can directly reach the entrance of the garage to transport the vehicle to the empty parking space. , It is necessary to use the ultrasonic sensor to check whether there is an obstacle in the parking space, if there is no obstacle, the parking will be completed directly, and if there is an obstacle, the obstacle removal operation (exception handling) will be performed.

The process of picking up the car from the garage is referring to accompanying drawing 2 and accompanying drawing 4, as shown in accompanying drawing 4, the first floor and the second floor in accompanying drawing 4 are respectively the first floor of the three-dimensional garage, and the number mark 1 is the No. 1 parking space, and the number mark is 2 is the No. 2 parking space, and the numeral mark 3 is the No. 3 parking space. As shown in accompanying drawing 4, there is a vehicle parked in the No. 1 parking space, and a vehicle is parked in the No. 2 parking space, and there is no vehicle parked in the No. 3 parking space.

For the vehicles parked in the garage, its height must reach the height standard of the garage, so there is no need to perform height detection when picking up the car. The whole picking up process is as follows.

First of all, if you need to take the vehicle in the No. 2 parking space, you can directly transport the vehicle on the No. 2 parking space. If you need to move the vehicle in the No. 1 parking space, you need to find a spare parking space. By calling the data in the PLC, set up It is found that the nearest empty parking space is the No. 3 parking space on the 2nd floor, then the No. 3 parking space is a spare parking space, and the carrier will move the vehicle on the No. After the vehicle in the No. 3 parking space is transported to the No. 3 parking space, the vehicle in the No. 2 parking space is transported to the exit of the garage, and the information recorded in the PLC is updated after the transportation is completed.

If an obstacle is found during the above-mentioned whole handling process, the obstacle removal process (ie exception handling) will be carried out.

The above is only a preferred embodiment of the present invention, and does not therefore limit the scope of patent protection of the present invention. All equivalent transformations made by using the description of the present invention, directly or indirectly used in other related technical fields, are all included in the same way. within the protection scope of the present invention.
