Description

Technical Field

[0001] This utility model relates to a control system for a multi-level parking garage, and more particularly to a PSH multi-level parking garage control system that can meet the control needs of small parking spaces. Background Technology

[0002] With the acceleration of urbanization, the parking problem is becoming increasingly severe. Traditional ground parking lots can no longer meet daily parking needs, while multi-level parking garages, as an efficient parking method, are gradually gaining popularity. Among them, PSH (lift-and-slide) multi-level parking garages can realize multi-level parking of vehicles. They can make full use of vertical space and significantly increase the number of parking spaces per unit area. Compared with traditional parking lots, they make full use of space resources and increase the parking lot's volume ratio. Therefore, for some large public places, PSH multi-level parking garages are widely used due to their convenient and efficient control advantages. However, for some small places, the control system structure of conventional PSH multi-level parking garages is very complex, and the purchase and use costs are high, making application difficult. Therefore, how to build a control system that can meet the needs of small parking spaces has become an urgent technical problem to be solved. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a PSH automated parking system that has a simple structural design, is easy to control and operate, and has low construction, use and maintenance costs.

[0004] To solve the above-mentioned technical problems, the PSH three-dimensional parking garage control system of this utility model includes two parking spaces for parking cars on the upper and lower levels, parking space drive motors for driving each parking space to move, KM1 contactors for controlling the downward / rightward movement direction, and KM2 contactors for controlling the upward / leftward movement direction. Each parking space drive motor is connected to a motor drive contactor and can be driven by its own motor drive contactor. Each motor drive contactor is connected to KM1 contactor and KM2 contactor respectively and can cooperate with KM1 contactor or KM2 contactor to perform parking and retrieval operations.

[0005] The coils of KM1 and KM2 are driven by a PLC control system, and their main contacts are connected to a 380V power supply line.

[0006] The 380V power supply line is electrically isolated from the control circuit of the PLC control system through a switching power supply U1.

[0007] A phase relay is installed on the 380V power supply line.

[0008] A thermal imaging camera connected to the PLC control system is installed next to the parking space.

[0009] The parking space drive motor includes motor 1, motor 2, motor 3, motor 4 and motor 5, and the motor drive contactor includes contactor KM101 for motor 1, contactor KM102 for motor 2, contactor KM201 for motor 3, contactor KM202 for motor 4 and contactor KM203 for motor 5.

[0010] With the above structure, by setting up a KM1 contactor for downward / rightward direction control and a KM2 contactor for upward / leftward direction control, and with each motor drive contactor connected to the KM1 and KM2 contactors respectively, the motor can cooperate with either the KM1 or KM2 contactors to perform parking and retrieval operations. This cleverly allows the parking space drive motors to share forward and reverse contactors, reducing not only the number of contactors but also the number of PLC output points, saving costs and improving control reliability. Car owners can easily complete the parking and retrieval process, enabling rapid vehicle storage and retrieval, thus greatly improving the convenience and efficiency of parking and retrieval. The entire control system is very simple and easy to operate, with low system construction and maintenance costs. It is particularly useful in small parking spaces, playing a crucial role in solving parking problems. Furthermore, the use of thermal imaging cameras to monitor parking space temperature allows for rapid response to various temperature anomalies and fire alarms, improving safety.

[0012] Figure 2 This is a schematic diagram of the parking space status in this embodiment. Detailed Implementation

[0013] The PSH automated parking system of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] As shown in the figure, the PSH automated parking system of this utility model includes two levels of parking spaces for parking cars. Figure 2The diagram shows the parking spaces in their respective positions. As can be seen from the diagram, the upper-level parking spaces, from left to right, are spaces 201, 202, and 203; the lower-level parking spaces, from left to right, are spaces 101 and 102. Space 101 has a first motor M101 for driving its left and right movement; space 102 has a second motor M102 for driving its left and right movement; space 201 has a third motor M201 for driving its up and down movement; and space 202 has a fourth motor M20 for driving its up and down movement. 2. Parking space 203 has a No. 5 motor M203 for driving its vertical movement. Motor 1 is connected to contactor KM101 (Mr. 1), Motor 2 is connected to contactor KM102 (Mr. 2), Motor 3 is connected to contactor KM201, Motor 4 is connected to contactor KM202, and Motor 5 is connected to contactor KM203. It also includes contactor KM1 for down / right movement control and contactor KM2 for up / left movement control. Contactors KM1 and KM2 are connected to... The contactor coil is driven by the PLC control system, and its main contacts are connected to a 380V power supply line. A phase relay is installed on the 380V power supply line. The 380V power supply line and the control circuit of the PLC control system are electrically isolated through a switching power supply U1. Contactors KM101, KM102, KM201, KM202, and KM203 are all connected to the output terminal of contactor KM1. Similarly, contactors KM101, KM102, KM201, KM202, and KM203 are also connected to the output terminal of contactor KM2. Thus, they can cooperate with contactor KM1 or contactor KM2 to perform vehicle storage and retrieval operations. Through this structural design, the parking space drive motor shares the forward and reverse contactors, which not only reduces the number of contactors but also reduces the number of PLC output points, saving costs. At the same time, the PLC control system has an industrial touch screen as a human-machine interface, is powered by 24V DC, is safe and reliable, and is compatible with various bus controls.

[0015] Furthermore, the PLC control system is equipped with a switching power supply U1, and a thermal imaging camera connected to the PLC control system is installed next to the parking space. The thermal imaging camera monitors the temperature of the parking space and can quickly respond to various temperature anomalies and fire alarms.

[0016] The operation method is as follows:

[0017] Parking space 201 parking space retrieval: First, parking spaces 101 and 102 need to be moved to the right. After contactor KM1 is energized, contactors KM101 and KM102 are simultaneously energized and move to the right. After parking spaces 101 and 102 are in place, contactors KM101 and KM102 are de-energized, and contactor KM201 is energized. After the parking space descends to its final position, contactors KM201 and KM1 are de-energized. After parking is completed, wait for the next operation.

[0018] Parking space 202 parking space retrieval: There are two scenarios, with either parking space 101 or 102 occupied. When parking space 101 is occupied, it first moves to the left, energizing KM2 and KM101. After parking space 101 is in its final position, KM2 and KM101 are de-energized, while KM1 and KM202 are energized. Parking space 202 then descends. Once in its final position, KM1 and KM202 are de-energized. After parking is completed, wait for the next operation. When parking space 102 is occupied, it first moves to the right, energizing KM1 and KM102. After parking space 102 is in its final position, KM102 is de-energized, while KM1 and KM202 are energized. Parking space 202 then descends. Once in its final position, KM1 and KM202 are de-energized. After parking is completed, wait for the next operation.

[0019] Parking space 203: First, parking spaces 101 and 102 need to be moved to the left. After KM2 is energized, contactors KM101 and KM102 are simultaneously energized and move to the left. After parking spaces 101 and 102 are in position, contactors KM2, KM101, and KM102 are de-energized, and contactors KM1 and KM201 are energized. After the parking space is lowered to the correct position, contactors KM201 and KM1 are de-energized. After parking is completed, wait for the next operation.

[0020] It should be noted that parking spaces 101 and 102 on the lower level are simply moved left and right to make room for parking spaces 201, 202, and 203 on the upper level to descend.

[0021] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
