1 Introduction

With the popularity of the car, parking is difficult to have a static traffic problems faced by large- and medium-sized cities to become a social problem, and even to some extent, restrict the development of China’s automobile industry, government and the community has paid great attention to the car parking problem. The three-dimensional (3D) garage automated 3D garage and to maximize use of space, large-scale 3D garage have developed rapidly [1].

Abroad in the research and manufacture of parking earlier, mainly Japan, South Korea and Germany, Japan in 1960 completed a four-car parking spaces, two-stage mechanical parking garage in 1971, began to develop assembly self-propelled 3D garage, Japan technology research and development aspects of the parking garage in a leading position, the number of completed parking and vehicle capacity is also highest in the world, Japan has put into use mechanical parking spaces over more than 300 million; South Korea in the 1970s of the twentieth century follow the example of Japan, with nearly 100 manufacturing enterprises, the annual growth rate of 30 % due to the attention of the government; the parking industry is very developed in Germany, production of parking equipment manufacturers, about 24, in owhich KLAUS and the OTT OWOHR two production accounts for about 80 % of the total output of Germany, have an advantage in the laneway type of product technology [2].

In the early 1990s, China started to develop and use mechanical parking equipment through the introduction of technology to fully digest and analysis, and the actual usage of domestic transformation and innovation, the path of independent development, has been the formation of new parking Equipment industry [3–5].

2 System Structure and Function

Automated 3D garage system is not directly for manual processing, transportation equipment can automatically multi-storey garage storage systems, warehousing operations system including multi-storey car parking spaces in the parking within the roadway to transport equipment out of storage and computer control and communications systems. Automated 3D planning and layout of the garage is related to the field of logistics and monitoring technology, computer application technology, communications technology, equipment and parking optimal management of technology, integrated project, it is characterized by a high-level 3D parking signs, complete sets of advanced handling equipment, advanced computer control technology as the main means highly efficient use of parking spaces and storage space, save time and effort out of storage operations. Among them, the computer monitoring system is an automated parking system core, is an important part of the stereo garage, and directly determines the level of automation of the 3D garage, to ensure the safety premise out of the library operating speed.

2.1 Computer Monitoring System Structure and Composition

According to the characteristics of the automated 3D garage and on-site needs, system architecture uses a layered approach to achieve the designed computer control system divided into functional management, monitoring layer, control layer 3, according to user requirements and the actual situation in management and monitoring layer merge management control layer, multimedia guide system equipment (card reader, display brand and identity, and charges for terminal system equipment) reader layer monitoring server connection directly with the management and monitoring system constitutes Fig. 13.1.

Automated parking computer monitoring system consists of host specific real-time monitoring system, garage management system, management information systems, field bus communication system, the ARM device control system, the storage authentication system, and other subsystems. Among them, the PC monitoring system responsible for automatically assigned parking spaces, enter the operating instructions, monitoring equipment operation, determine the state of equipment and fault; garage management system responsible for the processing of parking management, ID card management, charge management, permissions management, etc.; field bus communication system is responsible for the upper control and lower equipment real-time communications, transmission operating instructions and garage parking spaces and equipment state; ARM control panel device control system according to the operating instructions to control the operations of the equipment order; responsible for the user card system out of storage a personal identification system, access to information, the storage card and operating 3D garage under the control and management of the monitoring system to complete the entire garage automatically ordered high-efficiency operation.

2.2 Main Functions of the System Implementation

  1. (1)

    Automatic allocation of parking spaces, a variety of operating instructions sent to the ARM control panel, control equipment operation, real-time monitoring, display, record the state of equipment, and parking spaces in use for 24 h unattended automatic deposit/pick up the car, identity verification and management fees, the overall compact automated parking Kuguan control the integration.

  2. (2)

    Four sets of equipment can operate in parallel automatic deposit/pick up the car, authentication, and charging management.

  3. (3)

    Four sets of stackers, lift adjacent stacker, lift mutual backup software can be set to switch stackers, to achieve near-zero system downtime, maintenance time, to achieve high system reliability and high availability.

  4. (4)

    Authentication charges the credit card equipment using non-contact RF card technology, security, identification, storage/pick up the car, and charges to use the voice prompts and digital display of the two interfaces at the same time convey information from/to to take the car user-friendly and convenient.

  5. (5)

    And the concerted action of the library fire protection system, fire alarm occurs can command stacker abort the current task return to a safe area with the fastest speed.

  6. (6)

    The levels of operating rights management and database encryption, automatic backup, have a good data security.

  7. (7)

    To achieve real-time record of equipment failures and alarms, equipment, health records, to provide data for equipment maintenance.

  8. (8)

    Automatically optimizes the shortest path for bicycles, and pipeline operations in accordance with the instruction serial number of each car provides continuous access to an average speed of 86 s.

  9. (9)

    The three-tier design, management information systems using C/S structure, the overall system has good scalability and good versatility.

  10. (10)

    The completion of the implementation of the records, management of the garage to run a variety of information, such as the unusual circumstances of the equipment, instructions, fees, etc. improve the current data and historical data query capabilities, the flexibility to generate and print a variety of statistical reports.

  11. (11)

    And friendly man–machine interface, real-time dynamic display of the garage operation of equipment, work location, the state of equipment, parking spaces occupied.
