Stereo parking garage control system

Technical field

The invention relates to a garage control system, in particular to a stereo parking garage control system.

Background technique

With the impact of major events such as the 2008 Beijing Olympics and the 2010 Shanghai World Expo, as well as the further driving of domestic demand and the “fee-to-tax” policy, China’s motor vehicle ownership continues to grow at a high rate, and the average annual growth rate continues to rise. The average annual growth rate of private cars is even faster. However, according to the results of the general survey of parking facilities and preliminary predictions, China's static traffic infrastructure has been seriously behind the dynamic traffic infrastructure, and the national parking space gap is on average more than 60%. The survey shows that parking in public places is difficult in the city. universal. However, due to the increasing scarcity and high cost of urban land resources, many cities are already in a state of land, and it is unrealistic to use a large amount of land resources to meet the demand for parking spaces. The limited land area in the city has not been able to provide enough parking spaces, so replacing the traditional garage with a three-dimensional garage will become an important way to solve the current difficult parking problem.

Asia's mechanical three-dimensional parking equipment technology originated in Japan. Japan has been engaged in the development, production, sales and service of mechanical parking equipment since the 1960s. It has a history of more than 50 years. At present, there are more than 200 companies engaged in the development and manufacture of mechanical parking garages and their equipment in Japan. Among them, there are more than 100 companies producing mechanical parking equipment. The larger companies include Xinminghe, Ishikawajima, Nissei and Mitsubishi. Heavy work, etc. Since the 1990s, Japan has been operating more than 100,000 mechanical parking berths per year. At present, there are more than 3 million mechanical parking spaces in Japan, including lifting and traversing parking equipment.

Korean mechanical parking equipment technology is a derivative of Japanese technology. The industry started in the mid-1970s. In the 1980s, Japanese technology was introduced. After parallel production and localization, the supply phase began in the 1990s. Since these stages have been highly valued by the government, various mechanical parking equipment has been developed and utilized in general, and Korea has grown at a rate of around 30% in recent years. At present, the Korean parking equipment industry has entered a stage of steady development.

European countries such as Germany and Italy are also engaged in the development and production of parking equipment. The better companies are: Sotefin, Interpark, and Pali, Germany. Due to the relatively abundant land resources in European countries, the parking problem is not very prominent, and the application of parking equipment is not very large. Most of them are roadway stacking products, and there are fewer applications for multi-layer lifting and traversing products.

At present, the world machinery parking industry is diversified, and its parking technology includes almost all mature advanced technologies in the fields of machinery, electronics, hydraulics, optics, magnetron and computer technology. In terms of machinery, many new materials and processes have been applied. The device structure is modular in design, easy to use in combination, easy to install and disassemble. The steel structure adopts new high-quality steel, which not only improves the strength and rigidity of the equipment, but also makes the equipment light and beautiful. The loading board is assembled by one-time galvanized sheet or color coated board, which is beautiful, strong and durable. In terms of control technology, programmable controller and vector variable frequency variable speed control closed-loop control technology are widely used to make high-speed translation, saving power, vibration and noise. Control forms are: button type, Key type, IC card type, keyboard type, touch screen type, remote control type, etc. The safety components adopt various grating display screens, photoelectric tubes, mechanical travel switches, magnetic proximity switches, photosensitive sensor switches, etc. The safety protection devices are perfected, such as the sound and light guidance and positioning of the car, the automatic identification of the size and weight of the car, and the speed limit. Protection and multi-mechanism interlocking, automatic parking tracking, chain and wire rope length over-range alarm and elastic deformation automatic compensation, car image photography contrast safety detection, automatic fire extinguishing system.

In the early 1980s, China began to develop mechanical three-dimensional garages. In the 1990s, there was a rapid development. From the import of the first vertical circulation garage in 1992 to the establishment of the Stereo Parking Equipment Association in 1996, the process from product and technology introduction to independent development and manufacturing was completed in just a few years. Various types of garage equipment have emerged in the past few years, and members of the association have grown to more than 60 companies and research institutes. The technology of China's three-dimensional parking equipment mainly comes from Japan. At the beginning of production, most of them were imitations of products from Japan and other countries. After years of efforts, they have formed a certain scale of production and market. According to statistics from relevant parties, there are currently more than 100 production companies, and a nationally recognized three-dimensional parking equipment manufacturing enterprise qualification certification center has been established. A large part of the products come from independent development projects, and the level of production technology has also been greatly improved. At present, domestic three-dimensional parking equipment is mainly based on lifting and traversing, accounting for about 84% of the total. There are also vertical lifting and plane moving classes. In terms of technology, the hydraulic transmission type, mechanical hydraulic transmission type and electric transmission type are gradually developed from the initial mechanical transmission type. The control method has also evolved from simple manual control to electrical control, PLC control and fieldbus control.

detailed description

As shown in Fig. 1, a stereo parking garage control system includes a PLC. The input end of the PLC is connected with an emergency stop button, a travel switch and a photoelectric switch. The output end of the PLC is connected with a driver and an audible and visual alarm, and the drive is also connected. The lifting and traversing motor, the lifting and traversing motor are respectively installed in each parking space, the PLC is also connected with the man-machine interface, and the human-machine interface is connected with the identification system.

The automatic control system also comprises an automatic gate system, an automatic access system, a charge management system and a monitoring and security system. The above subsystems are uniformly managed by the central control room to plan the garage management form for the customer and ensure the safety of the garage.

The PLC has 32 inputs and 24 outputs, and expands into a dual MODBUS interface. One port is used to connect to the human machine interface, and one port is used to connect the card and the smart identification system.

Garage control methods are divided into: manual and semi-automatic, fully automatic. Manually, the jog control is carried out on the pallet by the manual operator on the spot; the automatic operation is selected by the PLC combined with the man-machine interface for the parking space selection. The fully automatic operation is composed of the PLC and the card swipe system, and the PLC realizes the automatic logic control according to the card swiping information. The manual mode is mainly used for maintenance commissioning or abnormal condition processing, which is the highest priority. The automatic mode is used for normal entry and exit processing, and can be used for unattended operation and interlocking between operating conditions.

When working, the PLC receives and analyzes the operator's control panel buttons and intelligent identification information, making reasonable arrangements: judging the status of the detection component, reading the information of the garage mechanical drive part, feeding back the information to the actuator, and dragging the parking board. Realize its position movement, complete the vehicle access operation and signal display. Through photoelectric detection, hardware and software signal interlocking, limit, anti-drop protection, overload protection and other devices to ensure the safe and smooth operation of the entire system.

The PLC in the system mainly completes the detection of the position of the pallet, the pallet and the running state and the operation of the access vehicle. Use various photoelectric switches and travel switches to detect the position status, and use the contactor and relay to control the start and stop of the drag motor. The operation of the parking space controls the traverse of the small motor and the lifting of the large motor so that they can achieve positive and negative reversal at different times. Moreover, the upper lifting movement and the lateral movement of the following layers are interlocked, that is, when the upper berth is moving up and down, the lower berths cannot move, and vice versa. And the upper berth can only have one berth at a time for up and down movement.

Process control process:

11,P111, P1	12,P212, P2	P3P3	21,P421, P4	22,P522, P5	P6P6

The car is indicated by 11, 12, 21, 22, 31, 32, 33, and the trolley access position is represented by P1, P2, P3, P4, P5, P6, P7, P8, P9. The above table is the initial state, P6, P3 position is empty, the cart 12 can move to the P3 position, 22 can move the P6 position, and 33 can move the P3 position.

At the beginning of the access to the car, first determine whether the cart tray is in the initial position, the initial position is as shown above, if not in the initial position Moving to the initial position and then accessing the car from the initial position, that is, doing a "return to zero" state, can greatly reduce the movement process of the access vehicle. The "return to zero" action can be performed during the swiping process, or it can be automatically executed after a delay after the access is completed.

The trolleys 11, 12 can be accessed directly without the need to move the trolley tray position.

The trolley 21 access can be moved in the following direction, the cart tray 12 moves to the P3 position, the cart tray 11 moves to the P2 position, and the cart tray 21 moves to the P1 position.

The trolley 22 access can be moved in the following direction, and the trolley tray 12 moves to the P3 position.

The cart tray 22 moves the P2 position.

The trolley 31 can be moved in the following direction, the cart tray 12 moves to the P3 position, the cart tray 11 moves to the P2 position, the cart tray 22 moves to the P6 position, the cart tray 21 moves to the P5 position, and the cart tray 31 moves to the P1 position.

The trolley 32 access can be moved in the following direction, the cart tray 12 moves to the P3 position, the cart tray 22 moves to the P6 position, and the cart tray 32 moves to the P2 position.

The cart 33 access can be moved in the following direction, and the cart tray 33 moves to the P3 position.

Figure 2 is a schematic view of the structure of the three-dimensional garage. The structure of the lifting and traversing intelligent stereo parking garage is that the bottom layer can only be translated, the top layer can only be lifted and lowered, and the middle layer can be both translated and lifted. In addition to the top layer, an empty parking space must be reserved for the middle and bottom floors for use in moving in and out of the vehicle. When the bottom parking space enters and exits the vehicle, it can directly enter and exit the vehicle without moving other trays. When entering the vehicle at the middle layer and the top layer, it is necessary to judge whether the corresponding lower position is empty. If it is not empty, the corresponding translation processing should be performed until the lower part is below. If it is empty, it can be lowered and moved in and out. After entering and leaving the car, it will rise back to the original position. The lifting and traversing parking garage uses the displacement of the tray to generate a vertical passage, and realizes the high-level parking space to lift and access the vehicle. The general principle of motion is: lifting reset, translation reset. Figure 1 is a schematic view of a 3 x 3 lifting and traversing stereo garage.

The mechanical system of the lifting and traversing stereo garage is mainly composed of a steel structure skeleton 1, a loading plate device 2, a transmission device and a safety protection device. The steel structure skeleton 1 part constitutes the "ribs" of the garage, mainly supporting the entire garage; the car board device 2 part is mainly used to carry the motor vehicle; the transmission part is used to complete the vehicle access function; and the safety protection device 3 is mainly used to improve the performance of the garage to improve the stability of the system.
