[0041] The present invention will be described in further detail below with reference to the accompanying drawings.

[0042] Figure 1 The figure shows the structural framework of the existing three-dimensional parking garage. Figure 1 The existing parking garage includes multiple parking units A. Each parking unit A can include a front row mechanical parking space A2 and a rear row mechanical parking space A1. Each row of parking spaces can include upper and lower layers of mechanical parking spaces. Figure 1 The smaller rectangular box in the middle represents the second-floor parking spaces, and the larger rectangular box represents the first-floor parking spaces; each parking floor can include multiple parking spaces A12 / A21, and each row of parking spaces has an empty parking space A11 / A22 on the first floor. The first floor can only move horizontally, and the second floor can only be raised and lowered. When the rear-row car comes out, the front parking space must create a corresponding passage. The empty parking space on the first floor is for vehicles entering and exiting the second floor or the rear row.

[0043] Figure 2 The control structure diagram of the existing multi-story parking garage is shown in FIG. Figure 2The control structure of the multi-story parking garage includes a control cabinet 2' and an operator 1'. The operator 1' is electrically connected to the control cabinet 2' and is used to send parking and retrieval information to the control cabinet; the control cabinet 2' has a controller 21', and each controller 21' includes a parking and retrieval control unit 21A'. The parking and retrieval control unit 21A' corresponds one-to-one with a parking unit A and is used to control the parking unit A to perform parking and retrieval operations according to the parking and retrieval information.

[0044] based on Figure 2 In the control structure of the multi-story parking garage shown, each parking unit A requires a control cabinet 2', so multiple parking units A require multiple control cabinets 2' and multiple operators 1'. The control cabinet 2' not only needs to include a controller 21', but also needs to include the power supply equipment, wiring equipment, etc. required by the controller 21' and the operator 1', so the cost is relatively high.

[0045] In view of this, please refer to Figure 3 , Figure 3 The figure shows a block diagram of the control structure principle of a multi-story parking garage provided by the present invention. The control structure includes a control cabinet 2 and an operator 1. The control cabinet 2 has a controller 21. The operator 1 is electrically connected to the controller 21 and is used to send parking and retrieval information to the controller 21. Each controller 21 includes at least two parking and retrieval control units 21A. The parking and retrieval control units 21A correspond one-to-one with the parking units A and are used to control the parking units A to perform parking and retrieval operations based on the parking and retrieval information.

[0046] For more details, please refer to Figure 3 In the present invention, each controller 21 can have at least two parking and retrieval control units 21A. Thus, each control cabinet 2 can control at least two parking units A to perform parking and retrieval operations. Figure 3 and Figure 2 Compared with the structure shown, if the application Figure 2 The structure shown in the figure is used to control the access of the car in the three-dimensional parking garage. The number of control structures required for the three-dimensional parking garage is the same as the number of parking units in the three-dimensional parking garage. However, if the application Figure 3 If the structure shown is used to control the storage and retrieval of vehicles in a three-dimensional parking garage, the number of control structures required for the three-dimensional parking garage will be reduced by at least half, thereby reducing the cost of the control structure of the three-dimensional parking garage and reducing the floor space occupied by the control structure of the three-dimensional parking garage.

[0047] Figure 4 The diagram shows a partial structure diagram of a controller in the prior art. Figure 4In the prior art, the controller 21' is a PLC controller, which includes an address unit 21B' and a parking and retrieval control unit 21A'. The operator 1' includes an information input unit 11'. The user sends parking and retrieval instructions, such as the parking space number, to the controller 21' through the information input unit 11'. The parking and retrieval instructions are stored in the address unit 21B', and the parking and retrieval control unit 21A' scans the instruction information in the address unit 21B' to perform the parking and retrieval operation. During the parking and retrieval process, the instruction information will continue to occupy the address unit 21B' until the parking and retrieval is completed.

[0048] Figure 5 The diagram shows a partial structure diagram of the controller provided by the embodiment of the present utility model. Please refer to Figure 5 The controller 21 is a PLC controller, which includes an address unit 21B and two parking and retrieval control units 21A. The two parking and retrieval control units 21A share the address unit 21B. In this way, during the parking and retrieval process, when a parking unit A is being parked or retrieved, the other parking unit A cannot be parked or retrieved because the address unit 21B is occupied.

[0049] Figure 6 The diagram shows a partial structure diagram of the controller provided by the embodiment of the present utility model. Please refer to Figure 6 The controller 21 is a PLC controller, which includes two parking and retrieval vehicle control units 21A and an address unit 21B corresponding to each parking and retrieval vehicle control unit 21A; the operator 1 includes an information input unit 11 and a two-position selection switch 12, and the two-position selection switch 12 is used to select the information input unit 11 and one of the address units 21B.

[0050] Specifically, in some optional embodiments of the present invention, the controller 21 includes two parking and retrieval control units 21A and an address unit 21B corresponding to each parking and retrieval control unit 21A; the operator 1 also includes a two-position selection switch 12. In this way, when parking and retrieval, the information channel between the information input unit 11 and one of the address units 21B can be selected through the two-position selection switch 12. In this way, when the user sends a parking and retrieval instruction, such as a parking space number, to the controller 21 through the information input unit 11; the parking and retrieval instruction will be stored in the selected address unit 21B, and the parking and retrieval control unit 21A corresponding to the selected address unit 21B will perform the corresponding parking unit. A's parking and retrieval operation; at this time, the other address unit 21B is not occupied by the instruction, so the user can also use the two-position selection switch 12 to select the information channel between the information input unit 11 and the other address unit 21B. In this way, when the user sends a parking and retrieval instruction, such as a parking space number, to the controller 21 through the information input unit 11; the parking and retrieval instruction will be stored in the other selected address unit 21B, and the parking and retrieval control unit 21A corresponding to the address unit 21B will perform the parking and retrieval operation of the corresponding parking unit A; at this time, the controller 21 realizes the effect of parallel parking and retrieval of the two parking units A, which can greatly save the time for parking and retrieval and improve the utilization efficiency of the control cabinet 2.

[0051] Figure 7 The above is a schematic diagram of the panel structure of the operator provided by the embodiment of the utility model. Figure 8 The figure shows the connection structure diagram of the display unit and the controller of the embodiment of the present utility model. Figure 7 and Figure 8 The operator 1 also includes a display unit 13; the display unit 13 is connected to the controller via RS485 and is used to display the status of the parking unit A. In this way, the user can understand the current parking and retrieval process and enhance the user experience.

[0052] Please continue to refer to Figure 7 In some optional embodiments of the present invention, the information input unit 11 includes a key input unit 112 and a sensor input unit 111. Both the key input unit 112 and the sensor input unit 111 can exchange data with the PLC controller via RS485 to convey the user's command information to the PLC controller. The sensor input unit 111 is used in conjunction with an induction card. When the user holds an induction card, the induction input unit 111 can send instructions to the PLC controller; when the user does not carry an induction card or cannot use an induction card, the key input unit 112 can send instructions to the PLC controller; in this way, the convenience of use can be improved.

[0053] Please continue to refer to Figure 7In some optional embodiments of the present invention, the sensor input unit 111 and the display unit 13 are arranged at overlapping positions. In this way, the area of ​​the operator 1 can be saved, and the operator 1 can be designed to be more compact.

[0054] Figure 9 The figure shows the internal device layout structure diagram of the control cabinet provided by the embodiment of the utility model. Please refer to Figure 9 The control cabinet 2 includes an electrical component setting area, which includes, from top to bottom, a first layer of electrical components 2A, a second layer of electrical components 2B, a third layer of electrical components 2C, and a fourth layer of electrical components 2D; the first layer of electrical components 2A includes multiple circuit breakers and multiple intermediate relays; the second layer of electrical components 2B includes multiple AC contactors and multiple thermal relays; the third layer of electrical components 2C includes a controller; and the fourth layer of electrical components 2D includes wiring terminals.

[0055] Take a parking mode as an example, such as the lifting and transverse moving type of three-dimensional parking garage, which uses the displacement of the loading plate to create a vertical channel to realize the lifting and retrieval of vehicles in high-rise parking spaces. Its parking space structure is Figure 1 The two-dimensional matrix shown in the figure is characterized by the following features: the ground floor can only move horizontally, the second floor can only lift, and an empty space must be reserved on the ground floor for vehicles to enter and exit the second floor or the rear first floor. Therefore, to store and retrieve vehicles, the second-floor loading plate and the rear first floor loading plate must be raised and lowered to create corresponding channels, thus requiring multiple motors to perform the lifting or lateral movement operations.

[0056] A control cabinet typically includes multiple circuit breakers, multiple intermediate relays, multiple AC contactors, multiple thermal relays, a PLC controller, and wiring terminals. The circuit breakers include a main power switch, a three-phase power switch for the motor, a PLC controller circuit breaker, and a socket circuit breaker. The multiple AC contactors are divided into multiple groups, each containing two mutually self-locking contactor groups. Each mutually self-locking contactor group corresponds to a motor, with the input of each self-locking contactor group connected to the output of the motor's three-phase power switch, and the output of each self-locking contactor group connected to the power supply of the motor via the thermal relay. The PLC controller is electrically connected to the coils and wiring terminals of the AC contactors.

[0057] In the present invention, the control cabinet 2 has a plurality of circuit breakers arranged on the first layer in terms of structural layout. In this way, the external power supply can be introduced into the control cabinet from the top of the control cabinet and electrically connected to the main power switch on the first layer. The main power switch can also be electrically connected to the three-phase power switch on the same layer. In this way, wiring is more convenient and wiring is simpler; secondly, the present invention arranges multiple AC contactors and thermal relays on the second layer. As mentioned above, the AC contactor group needs to be electrically connected to the three-phase power switch, and multiple AC contactor groups are in parallel with each other. Placing multiple AC contactors on the same layer and adjacent to the layer where the three-phase power switch is located is conducive to wiring; thirdly, in the present invention, the PLC controller is placed on the third layer. In this way, the PLC controller is close to the AC contactor and the wiring terminal, and the connection is very convenient.

[0058] Please continue to refer to Figure 9 In some optional embodiments of the present invention, the control cabinet 2 further includes a wiring area; the wiring area includes a first wiring trough 2E and multiple second wiring troughs 2F. The first wiring troughs 2E are located on both sides of and above the component placement area; the second wiring troughs 2F are located between adjacent component placement layers. This facilitates wiring between components and allows connecting wires to be neatly and simply arranged through the first wiring trough 2E and multiple second wiring troughs 2F. This improves electrical safety in the control cabinet and facilitates maintenance and inspection of the control cabinet.

[0059] Please continue to refer to Figure 7 In some optional embodiments of the present invention, the operator 1 further includes an operation mode selection switch 14 , and the operation mode selection switch 14 is connected to the controller 21 .

[0060] In some embodiments of the present invention, the operating mode selection switch 14 includes a manual mode, an automatic mode and a disabled mode; in manual mode, the user can enter the parking space number in the key area, and the controller 21 executes a manual program to move the parking space to store or retrieve the car; in automatic mode, the user can press the number keys in the key area or swipe the card to enter the parking space number, and the controller executes an automatic program to store or retrieve the car; in disabled mode, the controller program is not executed.

[0061] Please continue to refer to Figure 7 In some optional embodiments of the present invention, the operator 1 further includes an emergency stop button 15, which is connected to the controller 21. The emergency stop button is used to send a command to the controller 21 to stop the operation of the device in the event of a device failure or dangerous emergency.
