An efficient access method for a plane mobile three-dimensional garage with a ready-to-shift parking space

technical field

The invention relates to the field of mechanical parking equipment, and is an efficient access method for a plane mobile three-dimensional garage with a ready-to-shift parking space.

Background technique

In order to achieve a higher capacity, the current intelligent warehouse-type three-dimensional garage usually adopts a rearrangement arrangement (that is, one car is placed in the front and the rear, a total of two cars). When loading and unloading the car, usually first move the car on the front side of the heavy train bay to the fixed spare parking space, and then access the car on the rear side of the heavy train bay. Put the car on the fixed standby parking space back to its original position, and leave the standby parking space for the normal pick and place of the next car. Since the above-mentioned standby moving method has many action links, it is necessary to know how to set up the access car and the standby moving parking space. The location and how to store and transfer the data of the vehicle information and the data of the parking space information accurately are very complicated, and errors are prone to occur. It happens from time to time.

SUMMARY OF THE INVENTION

Aiming at the shortcomings of the prior art, the present invention provides an efficient access method for a plane mobile three-dimensional garage with a spare parking space, which can effectively improve the efficiency of car access and reduce the failure rate.

To this end, the present invention adopts the following technical scheme: an efficient access method for a plane mobile three-dimensional garage with a ready-to-shift parking space, which is characterized in that it includes a control system and various sensors, and the sensors receive signals and send them to the control system. System, the control system will record the vehicle information of each parking space in the garage and make judgments on the received signals according to the system program and control the lift or lateral movement of the carrier. vehicles and whether there are obstacles;

When parking the car, the system will preferentially store the vehicle in the vacant space closest to the entrance and exit and in the rear parking space. After the car is stored, the control system will update and store the information of the parked vehicle and the parking space in real time;

When picking up the car, if it is a front-row vehicle, the control system determines that there is no need to remove the blocking vehicle, and the control system controls the carrier to directly transport the picked-up vehicle to the entrance and exit to complete the pick-up; if it is a rear-row vehicle, the control system first determines that the front row Whether there is a vehicle in the parking space, if there is no vehicle in the front parking space, directly take out the vehicle in the rear parking space. If there is a vehicle in the front parking space of the vehicle taken, move the vehicle in the front parking space to the nearest vacant space first. Then remove the vehicle from the rear parking space.

Preferably, the calculation rule for taking out the rear row of vehicles when there is a blocking vehicle in the front row is: preferentially move the front row vehicle to the vacancy closest to the original parking space; when there are vacancies in the front and rear rows on the same floor, preferentially choose to move to the rear row vacancy; If there are multiple rear vacancies on the same floor, the rear vacancy closest to the original parking space will be preferred; if there are vacancies on the left and right sides of the same row of the roadway, the right rear vacancy will be preferred; when the rear row has vacancies When all the vacancies are full, the front row closest to the original parking space is given priority; if there are vacancies in the front row on the left and right sides of the same row of the roadway, the front row on the right is given priority.

As a preference, the vacancy on the floor closest to the entrance and exit is preferred when storing the car; when there are vacancies in the front and rear rows on the same floor, the vacancy in the rear row is preferred; if there are multiple vacancies in the rear row on the same floor, the closest vacancy in the elevator entrance and exit is preferred. The vacancy in the rear row of the row where it is located; if there are vacancies in the rear row on the left and right sides of the same row of the aisle, the rear row vacancy on the right side is preferred; when the rear vacancy on the floor closest to the entrance and exit is full, priority is given to the rear row. Select the vacant front row closest to the column where the elevator entrance and exit are located; if there are vacancies in the front row on the left and right sides of the same row of the roadway, the front row on the right is preferred;

As a preference, if one side of the roadway is a double-row parking space and the other side is a single-row parking space, when the three-dimensional garage control system receives the parking instruction, it will preferentially select the single-row vacant space closest to the entrance and exit when storing the car; single-row parking spaces on the same floor After the vacant space is full, if there are vacancies in the front and rear rows of the double-row parking space, the rear-row vacancy will be preferred; if there are multiple rear-row vacancies on the double-row parking space on the same floor, the one closest to the elevator entrance and exit will be preferred. When the rear vacancies on the double-row parking space on the floor closest to the entrance and exit are full, the front vacancy in the row closest to the elevator entrance and exit is preferred.

Preferably, if one side of the roadway is a double-row parking space and the other side is a single-row parking space, when the three-dimensional garage control system receives the vehicle fetching instruction, if the fetched vehicle is a front-row or single-row vehicle, the system determines that there is no need to remove the barrier Vehicles, directly transport the picked-up vehicle to the entrance and exit, and complete the pick-up;

If the vehicle taken is a rear-seat vehicle, the stereo garage control system will first determine whether there is a vehicle in the front-row parking space. If there is no vehicle in the front-row parking space, it will directly take out the vehicle in the rear-row parking space. Move the vehicle in the row of parking spaces to the vacant space closest to the original parking space, and then take out the vehicle in the rear parking space;

The specific calculation rules for moving the vehicle in the front row to the vacancy closest to the original parking space are as follows: the single row vacancy is given priority; when there are vacancies in the front and rear rows of both rows, the rear vacancy closest to the original parking space is given priority; When both the rear and single row are full, the vacant seat in the front row closest to the original parking space is preferred.

Preferably, the photoelectric sensor at the entrance and exit of the car determines whether the vehicle is super high. If it is normal, the process of parking the car is started. Otherwise, a super high alarm is issued to let the driver pull the vehicle out of the garage.

The beneficial effects of the present invention are: the vehicle will be preferentially parked in the rear vacancy near the entrance and exit, and when accessing the vehicle, the moving distance of the vehicle between the parking space and the entrance and exit is the shortest, and the time is also the shortest, reducing the working time of the moving machinery and equipment. The wear and tear improves the efficiency of the access car.

Detailed ways

The following describes in further detail the embodiments of the present invention and some comparative examples.

The invention discloses a high-efficiency access method for a plane mobile three-dimensional garage with a ready-to-shift parking space, which includes a programmable logic controller (PLC)-based control system and various sensors. The sensors receive signals and send them to the PLC. , PLC will record the vehicle information of each parking space in the garage and judge the received signal according to the system program. The sensor is used to detect whether there is a car and whether there is an obstacle in the induction entrance and parking space; Store the vehicle in the vacant space closest to the entrance and exit and store it in the rear parking space first. After accessing the vehicle, the system will update and store the information of the parked vehicle and the parking space in real time.

In this method, when the car is stored, the photoelectric sensor at the entrance and exit determines whether the vehicle is super high, and if it is normal, the process of parking the car is started, otherwise, a super high alarm is issued to let the driver withdraw the vehicle from the garage.

According to whether there are double-row parking spaces on both sides of the roadway, the system will also have different data analysis and judgment methods.

Example 1: When there are double-row parking spaces on both sides of the roadway, store the car

If there are double-row parking spaces on both sides of the roadway, when the three-dimensional garage control system receives the parking instruction, it will preferentially select the vacant space closest to the entrance and exit. The specific calculation rules are:

If there are vacancies on many floors in the garage, the vacancy on the floor closest to the entrance and exit is preferred; when there are vacancies in the front and rear rows of the same floor, the rear vacancy is preferred; if there are multiple rear vacancies on the same floor, the most vacant seat is preferred. The rear vacancy in the row where the elevator entrance and exit are located; if there are vacancies on the left and right sides of the roadway in the same row, the rear vacancy on the right is preferred; when the rear vacancy on the floor closest to the entrance and exit is full After that, the vacant seat in the front row closest to the elevator entrance and exit is given priority; if there are vacancies in the front row on the left and right sides of the same row of the roadway, the front vacancy on the right side is given priority;

The following will illustrate the specific data analysis judgment and implementation method of the parking process when there are double-row parking spaces on both sides of the roadway:

As shown in Figure 1, it is a 4-story flat mobile three-dimensional garage. The entrance and exit of the garage are on the ground floor, and there are 4 floors of parking underground, which are 1, 2, 3, and 4 floors from top to bottom.

Before a new three-dimensional garage is put into use, the system will default to all parking spaces as empty spaces, as shown in Figure 1.1. When a vehicle starts to be stored, the system will first automatically assign a rear vacancy (the system can set its number to 101) on the right side of the 1st column on the 1st floor to the vehicle, and then the lift and traverse mechanism of the garage According to the received system instructions, the carrier and the carrier will act together to send the vehicles at the entrance and exit to the 101 parking space. At the same time, the system will store the information of the vehicles already parked in the 101 parking space into the memory, that is, the 101 parking space will no longer be displayed as There is an empty parking space, and the display shows "cars available", as shown in Figure 1.2. By analogy, the second car will be stored in the rear vacancy on the left side of the 1st column on the 1st floor (the system can set its number to 201), as shown in Figure 1.3.

When the rear vacancies on the first floor are fully parked, as shown in Figure 1.4, if there are more vehicles to be stored, the system will automatically assign a front vacancy on the right side of the first column on the first floor (the system can Set its number to 301) to the vehicle, as shown in Figure 1.5, and so on

When all the parking spaces on the first floor are full, the system starts to park the vehicles on the empty parking spaces on the second floor. The specific allocation principle is the same as that on the first floor, and so on.

Example 2: When one side of the roadway is a double-row parking space and the other side is a single-row parking space, store the car

If one side of the roadway is a double-row parking space and the other side is a single-row parking space, the three-dimensional garage control system will preferentially select the single-row vacant space closest to the entrance and exit when receiving the parking instruction. The specific calculation rule is: There are many floors in the garage. If there are vacancies, the vacancy on the floor closest to the entrance and exit will be preferred; when there are vacancies in both single-row and double-row on the same floor, the single-row vacancy will be preferred. When there are vacancies in the front and rear rows, the rear vacancy is preferred; if there are multiple rear vacancies on the double-row parking side on the same floor, the rear vacancy closest to the row where the elevator entrance and exit are located is preferred; when the floor closest to the entrance and exit is located When the rear vacancies on the side of the double-row parking spaces are full, the front vacancies closest to the elevator entrance and exit are given priority.

The following will illustrate the specific data analysis judgment and implementation method of the parking process when one side of the roadway is a double-row parking space and the other side is a single-row parking space:

As shown in Figure 2, it is a 4-story flat mobile three-dimensional garage. The entrance and exit of the garage are on the ground floor, and there are 4 floors of parking underground, which are 1, 2, 3, and 4 floors from top to bottom.

Before a new three-dimensional garage is put into use, the system will default to all parking spaces as empty spaces, as shown in Figure 2.1. When a vehicle starts to be stored, the system will first automatically assign a single-row vacancy (the system can set its number to 201) at the first column of the 1st floor to the vehicle, and then the lift, traverse mechanism and transport of the garage According to the received system command, the system will act together to send the vehicle at the entrance to the 101 parking space. At the same time, the system will store the information of the parked vehicle in the 201 parking space into the memory, that is, the 201 parking space will no longer be displayed as an empty parking space. , and the display has "car", as shown in Figure 2.2. By analogy, the second car will be stored in the single-row vacancy located in the second column of the 1st floor (the system can set its number to 202), and so on, until the single-row vacancy is fully parked, as shown in the figure 2.3 shown.

If there is another vehicle that needs to be stored, the system will automatically assign a rear vacancy (the system can set its number to 101) in the double vacancy on the 1st floor and the 1st column to the vehicle, as shown in Figure 2.4 , and so on

When the rear vacancies in the double-row vacancies are full of vehicles, as shown in Figure 2.5, the system will automatically allocate a front-row vacancy in the first-row double-row vacancies on the first floor when the vehicle continues to be stored. As shown in Figure 2.6.

When all the parking spaces on the first floor are full, the system starts to park the vehicles in the empty parking spaces on the second floor. The specific allocation principle is the same as that on the first floor, and so on.

Example 3: When there are double-row parking spaces on both sides of the roadway, take the car

If there are double-row parking spaces on both sides of the roadway, when the three-dimensional garage control system receives the car fetching command, if the fetched vehicle is the front row vehicle (such as 301), the system determines that there is no need to remove the blocking vehicle, and the garage lifts and traverses. The mechanism and the carrier directly transport the picked vehicle to the entrance and exit to complete the pick-up, as shown in Figure 3.1.

If the vehicle taken is a rear vehicle, the three-dimensional garage control system will first determine whether there is a vehicle in the front parking space. If there is no vehicle in the front parking space (eg 101), it will directly take out the vehicle in the rear parking space, as shown in Figure 3.2.

If there is a vehicle in the front parking space, first move the vehicle in the front parking space to the nearest vacant space, and then take out the vehicle in the rear parking space. The specific calculation rules are: the vacancy closest to the original parking space is preferentially selected; when there are vacancies in the front and rear rows on the same floor, the rear vacancy is preferentially selected; if there are multiple rear vacancies on the same floor, the rear vacancy closest to the original parking space is preferentially selected Empty seats; if there are vacancies in the left and right back rows of the same row in the roadway, the right rear vacancy will be preferred; when the rear vacancies are full, the front vacancy closest to the original parking space will be preferred. ; If there are vacancies in the front rows on the left and right sides of the same row of the aisle, the front row on the right is preferred.

The following will illustrate the specific data analysis judgment and implementation method of the car fetching process when there are double-row parking spaces on both sides of the roadway:

As shown in Figure 4, it is a 4-story flat mobile three-dimensional garage. The entrance and exit of the garage are on the ground floor, and there are 4 floors of parking underground, which are 1, 2, 3, and 4 floors from top to bottom.

If the vehicle taken is 102, then there are vacancies in the front and rear rows on one side of the roadway. As shown in Figure 4.1, the system will first automatically assign the rear vacancy on the right side of the third column as a spare vacancy (the front and rear rows on the same floor). When there are vacancies in the row, the rear vacancy will be selected first), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to move the vehicle in the 302 parking space to the 103 vacant space, as shown in Figure 4.2 shown. Then the lift, traverse mechanism and carrier of the garage will act together according to the received system commands to take out the vehicles in the 102 parking spaces, transport them to the entrance and exit, and wait for the driver to drive away, as shown in Figure 4.3.

If the vehicle taken is 101, there are multiple rear vacancies on one side of the roadway, as shown in Figure 5.1, the system will first automatically assign the rear vacancy on the right side of the second column as a spare vacancy (there are multiple If there is a vacant seat in the rear, the rear vacancy closest to the original parking space will be selected first), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to move the vehicle in parking space 301 to car 102. vacancy, as shown in Figure 5.2. Then, the lift, traverse mechanism and carrier of the garage will act together according to the received system commands to take out the vehicle in parking space 101, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 5.3.

If the vehicle taken is 102, then there are vacancies in the front and rear rows on both sides of the roadway. As shown in Figure 6.1, the system will first automatically assign the rear vacancy on the right side of the third column as a spare vacancy (two left and right in the same row). There are vacancies in the rear rows on the side, and the rear vacancy on the right is preferred), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to move the vehicle at parking space 302 to the 103 vacancies,

As shown in Figure 6.2. Then the lift, traverse mechanism and carrier of the garage will act together according to the received system instructions to take out the vehicle in the 102 parking space, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 6.3.

If the vehicle taken is 101, when the rear vacancies on both sides of the roadway are full, as shown in Figure 7.1, the system will first automatically assign the front vacancy on the right side of the second column as a spare vacancy (when After the rear vacancies are fully parked, the front vacancy closest to the original parking space will be selected first), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to move the vehicle in the 301 parking space. Move to vacancy 302, as shown in Figure 7.2. Then, the lift, traverse mechanism and carrier of the garage will act together according to the received system command to take out the vehicle in the 101 parking space, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 7.3.

If the vehicle taken is 101, there are front-row vacancies on both sides of the roadway, as shown in Figure 8.1, the system will first automatically assign the front-row vacancy on the right side of the second column as a spare-shift vacancy (the same row in the roadway on the left and right sides) If there are vacancies in the front rows on both sides, the vacancy in the front row on the right is preferred), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to transfer the vehicles at parking space 301. to the 302 vacancy, as shown in Figure 8.2. Then, the lift, traverse mechanism and carrier of the garage will act together according to the received system instructions to take out the vehicle in parking space 101, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 8.3.

Example 4: When one side of the roadway is a double-row parking space and the other side is a single-row parking space, take the car

If one side of the roadway is a double-row parking space and the other side is a single-row parking space, when the three-dimensional garage control system receives the car fetch command, if the vehicle taken is the front row (301 vehicle as shown in Figure 9.1) or a single row vehicle ( 201 vehicle as shown in Figure 9.2), the system determines that there is no need to remove the blocking vehicle, and the lift, traverse mechanism and carrier of the garage directly transport the fetched vehicle to the entrance and exit to complete the fetching.

If the vehicle taken is a rear-seat vehicle, the stereo garage control system will first determine whether there is a vehicle in the front-row parking space. If there is no vehicle in the front-row parking space, it will directly take out the vehicle in the rear-row parking space. The vehicle in the row of parking spaces is moved to the vacant space closest to the original parking space, and then the vehicle in the rear parking space is taken out.

The specific calculation rules for moving the vehicle in the front row to the vacancy closest to the original parking space are as follows: the single row vacancy is given priority; when there are vacancies in the front and rear rows of both rows, the rear vacancy closest to the original parking space is preferentially selected; When both the row and the single row are fully parked, the vacant seat in the front row closest to the original parking space is preferred.

The following will illustrate the specific data analysis judgment and implementation method of the car fetching process when one side of the roadway is a double-row parking space and the other side is a single-row parking space:

If the vehicle taken is 101, there are vacancies in both the single row and the double row in the roadway. As shown in Figure 10.1, the system will automatically assign the vacancy in the first row of the single row as a spare vacancy (priority single row vacancy), Then, the lifting, traversing mechanism and carrier of the garage will act together according to the received system commands to move the vehicle from parking space 301 to parking space 201, as shown in Figure 10.2. Then, the lift, traverse mechanism and carrier of the garage will act together according to the received system instructions to take out the vehicle in parking space 101, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 10.3.

If the vehicle taken is 101, there is no vacancy in the single-row parking space in the roadway, and there are vacancies in the front and rear rows of the double-row parking space in the roadway. The vacancies are allocated as spare vacancies (when there are vacancies in the front and rear rows of the double row, the rear vacancy closest to the original parking space is preferred), and then the lift, traverse mechanism and carrier of the garage will cooperate according to the received system commands. Action, move the vehicle at parking space 301 to the vacant space 102, as shown in Figure 11.2. Then, the lift, traverse mechanism and carrier of the garage will work together according to the received system instructions to take out the vehicle in parking space 101, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 11.3.

If the vehicle taken is 101, then only the front row of the double row has vacancies in the roadway. As shown in Figure 12.1, the system will first automatically assign the front row vacancy on the right side of the second column as a spare vacancy (rear row and single row). After the platoons are fully parked, the front row vacancy closest to the original parking space will be selected first), and then the lift, traverse mechanism and carrier of the garage will work together according to the received system commands to move the vehicle in the 301 parking space to the 302 parking space. , as shown in Figure 12.2. Then, the lift, traverse mechanism and carrier of the garage will act together according to the received system commands to take out the vehicle in parking space 101, transport it to the entrance and exit, and wait for the driver to drive away, as shown in Figure 12.3.
