1、附录 A：英文资料 PLC-based control of multi-storey parking study and design 1、 Overview of parking The application of parking facilities for over 30 years history of the older, better Japan, South Korea, Taiwan, Germany, is well known, Chinas economy has experienced 30 years of rapid growth, the quality of
2、 public life increasing demands, Community Map in the line to a new level. Subsequent transport situation is tense, Japan and Canada, which includes both dynamic and static. As the city high-rise buildings built by the level of housing reform, like parking shift from three-dimensional surface parkin
3、g, parking in a static traffic in the already occupied an increasingly important position.Underground parking garage, compared with the traditional, in many ways is the first section shows the superiority of the advantages of the past, underground garage vehicular access due Leave generous, the aver
4、age car would occupy 40 square meters of area, If using double-parking garage, the ground can increase the utilization rate of 80% -90%, if the use of multi-floor (21 floor) Three-dimensional garage, then the land area of 50 square meters will be placed on the 40 vehicles that can to save land resou
5、rces and reduce the cost of civil engineering development. For example, the Indonesian Embassy in Beijing did not build multi-storey parking before the plane can only put five cars are now built three-dimensional lifting and after class garage can park 13 cars, the basic requirements to meet the Emb
6、assy . It is generally considered good prospects for parking equipment industry and has been hailed as the 21st century, one of the most popular industry. 2、 Lifting and transferring the concept garage Parking equipment has provided a total of 9 categories: lifting and class (PSH), simple lifting cl
7、ass (PJS), vertical lifting type (PCS), the vertical circulation category (PCX), flat mobile class (PPY), tunnel reactor stack class (PXD), multi-cycle class (PDX), the level of circulating type (PSX), vehicle lift (PQS), there are dozens of specifications, can be applied to a different space, site
8、conditions, is a high security , high reliability, high efficiency of automation equipment. Especially in these types of lifting and 9 classes (PSH) parking most widely used. Used to set the rising and falling or sliding vehicle access to vehicles, parking garage equipment category called lifting an
9、d garage.Lifting and transferring garage modular design, each unit can be designed as two, three, four, five, half-underground, and other means, the number of parking spaces from a few to hundreds.As the lifting and transferring the pattern classes more parking, vary in size, strong adaptability to
10、the site, therefore, use of such equipment is common parking garage. Its working principle is: Each car parking spaces are presented board, set the required access to the vehicle by vehicle plate upward and downward, sliding movement to reach the ground floor, the driver entered the garage, access t
11、o vehicles, complete the access process.The upper or lower parking spaces need to traverse the space through the middle layer, will contain the vehicle plate up or down to ground level, the pilot before entering the garage or out a car into the garage.Figure 1 is lifting and parking equipment, engin
12、eering example class diagram. Figure 1 PSH-based three-tier parking equipment lifting and transferring class diagram 3、 three lifting and transferring parking system Lifting and transferring parking garage is a typical cross-disciplinary integration of mechanical and electrical products, mechanical
13、assembly, electronics, information technology in one. Lifting and transferring parking mainly by the steel parts, car panels containing part, the transmission system, control system, security system, five components, shown in Figure 2.Three mechanical parking equipment is lifting and machinery of a
14、type of parking equipment, this type of garage equipment in the middle of each layer, the ground floor are to remain free parking, ground floor only do sliding movement on the ground while doing Traversing the second floor done-and-down movement, the ground layer only do Movement. Run-time, ground f
15、loor direct access to cars； on the floor the second floor access vehicles, need to correspond through the ground floor containing the car sliding to the space station, the lift reached the ground floor to achieve； the ground three car access is required the second floor by floor, the ground floor of
16、 loading corresponding to the space station after traversing the same time, lift reaches the ground layer.The movement of general principles: down reset, translation is not reset.Parking parking required by the user specification and design, automatic and manual operation mode of two points, can be
17、switched on and off during normal operation in the garage to use automated means, in equipment maintenance and debugging can be used manually. Both automatic and manually controlled by PLC programmable controller, so devices can guarantee the safe operation of any manner. Equipment There are several
18、 safety devices to ensure safety of people and vehicles, such as anti-fall safety devices, limit and prevent excessive volume device, Automatic power-off braking device, the wrong break phase protection. 3.1 The main frame part Actual projects: Beijing Indonesia Embassy lifting and transferring clas
19、s parking, equipment overall structure simple, generous, give people lightweight sprightly feeling. Main steel structure uses H steel, channel steel, plate welding molding, use bolt connected framework struture strength and stiffness. Order steel part appearance beautiful and anti corrosion, antirus
20、t ability, steel some painting before adopted mechanical derusting processing so parking equipment overall surface protective level reached higher grade.In addition, the second set of equipment can be assembled and combined, can be installed to ensure reliable quality, favorable transport and reduci
21、ng on-site installation time. 3.2Car plates containing Set car plates are used to carry inventory of vehicles. Set car plates from the 2.3mm of galvanized sheet bending forming, around edge girder 4.5mm of galvanized sheet bending forming. Edge beam and set vehicles with no plate bolt connection, se
22、t car plates to ensure rigidity and strength. Resistance of loading plate with vehicle and stopper. 3.3Drive System Parking equipment drive system uses chain or rope traction drive transmission. The car parking facilities containing the upper plate by the lift motor gear driven by a chain-driven rol
23、ler, then roll through the rope-driven movements of loading plate. Two-story frame structure with sliding, respectively, each sliding frame with lifting and sliding the two motors, both frame by sliding the track traverse motor can also be set through the lifting motor vehicles to reach the rising a
24、nd falling ground level, achieving access to cars.The transmission mode compared with other methods, has run a smooth, safe and reliable maintenance and convenient, while its environmental performance is also superior to the other drive. The lower plate by a motor vehicle containing reducer to walk
25、through the chain drive wheel drive along the traverse track movement. Drive motor assembly gear reducer, motor and brake as a whole, small size, light weight, low noise, using long-term grease, stable and reliable performance, long life, long-term maintenance-free, quality superior.
