Parking Guidance System of Tianjin General Hospital
The General Hospital of Tianjin Medical University was founded in 1946. After 50 years of development, it has become the largest comprehensive university hospital in Tianjin that integrates medical treatment, teaching, scientific research, and prevention. It is also regarded as a tertiary first-class hospital, the national “top 100 hospitals”, and Tianjin Medical Center. The existing building area is about 76,756 square meters. There are 33 clinical departments, 12 medical technical departments, Tianjin Institute of Neurology, Tianjin Institute of Radiology, Tianjin Institute of Endocrinology, Clinical Department, Tianjin Institute of Sexually Transmitted Diseases. There are 2363 employees, including 1 academician of the Academy of Engineering, 14 doctoral tutors, 121 master tutors, 12 government-approved experts, and 327 persons with technical titles above associate senior level. It has 1,000 hospital beds, 800,000 outpatient visits per year, and 15,000 inpatient visits per year.
While there is an endless stream of people who come to the hospital every day, the cars waiting to enter the hospital at the entrance of the General Hospital are also coming to the hospital. It’s no surprise that the crowded cars on Anshan Road have long since been unsurprising. Sometimes the parking time has to catch up with the work time, but I can only do it in a hurry.
In order to solve the problem of the small parking lot, the General Hospital built a two-story underground large three-dimensional garage in the second phase of the hospital, and introduced some vehicles into the garage to reduce the queue of vehicles at the entrance of the hospital. However, new problems have arisen. The newly-built three-dimensional garage is less known to people, and the environment of the three-dimensional garage is complicated. It is easy for people who park to get lost in the parking lot, and it is easy to find their own car in the parking lot. The reason that restricts the function of the mechanical garage is precisely because of the lack of management “Bole”.
How to solve the management problem of this garage? After many considerations and comprehensive comparisons, the Tianjin General Hospital’s three-dimensional mechanical garage finally introduced Ketuo’s parking guidance system.
Ketuo’s parking guidance system collects real-time vehicle information of each parking space in the garage through the ultrasonic parking space detector installed on the fixed surface of each parking space in the three-dimensional garage. The node controller connected to the detector collects the information of each connected detector and feeds it back to the central controller. The central controller completes the data processing and sends the processed parking space data to the parking lot. The LED parking space display at the entrance of each internal channel will display the number of empty parking spaces in the current direction, and the LED parking space indicator above the vehicle will display red or green according to the vehicle status. When it displays red, it means there is a car, and when it displays green, it means an empty parking space. . So as to realize the function of guiding the vehicle into the vacant parking space. At the same time, the system will transmit the data to the computer, and the computer will store the data in the database server. The user can query the real-time parking space information of the parking lot and the year, month, and day statistics of the parking lot through the computer terminal.
1. Ultrasonic detector
Ultrasonic detector is an important part of the parking guidance system. It is installed on the fixed surface of each group of parking spaces in the three-dimensional garage. The parking space information is transmitted to the node controller in time.
2. LED parking indicator
Installed in front of each group of parking spaces, one group of parking spaces is equipped with an indicator light. When there is a free parking space, a green light is displayed, otherwise, a red light is displayed.
Three, node controller
The node controller is the middle layer of the three-layer network bus of the parking guidance system, which plays an important role in ensuring the safety, reliability and efficiency of the system. The node controller cyclically detects the status of the connected detectors and transmits relevant information to the central controller.
Fourth, the central controller
The central controller is the core of the entire system, mainly responsible for the collection and control of the entire intelligent parking guidance system, and realizes the guidance function of the vehicle by updating the real-time data of the parking guidance screen. A central controller can control up to 64 node controllers.
5. Indoor parking space guide screen
It is recommended to install parking guidance screens at important intersections inside the parking lot. The number of parking guidance screens and the displayed text content are customized according to customer needs. It receives the output information of the central controller and displays the parking position in the form of numbers, arrows, and text to guide the driver Quickly find the empty parking spaces allocated by the system. In this way, the traffic flow is allocated to the most suitable location in the parking lot to ensure the smooth flow of the parking lot and make full use of the parking spaces.
6. Outdoor parking space guide screen
Installed at each entrance of the parking lot, used to display parking space information in the parking lot. The number of small LED screens at the total entrance is set according to the number of areas divided by the parking lot, and the number of parking spaces in each area is displayed respectively. It receives the parking statistics information of the central controller, displays the number of free parking spaces in the current parking lot in real-time in numbers and text, and prompts the drivers of vehicles who are ready to enter the parking lot. It can be used 24 hours a day. The internal program can also be modified at any time according to user requirements to display other information required by the user.
The introduction of the parking guidance system in Tianjin General Hospital on the one hand improved the difficulty of parking in the hospital, so that people who came to see the doctor would no longer waste a lot of time waiting for parking spaces. On the other hand, the function of the three-dimensional garage was more comprehensive. In the process of entering and exiting the stereo garage, people enjoy more humane services and more thoughtful guidance, making parking a comfortable enjoyment.
