Chapter One Company Profile
With the development of science and technology and the in-depth popularization of computers, the role of computers in management has also evolved from the original single word processing to management control. Management tools form a pattern from manual management to computer-assisted management and computer management.
Shenzhen Bainian Songpu Technology Development Co., Ltd., adhering to the quality policy of “customer first, product quality, perfect service, mutual benefit of all parties”, specializes in gold card system application and brand agency. It has technical development, marketing, system engineering and customer service departments, and has a complete management system. The main systems are: access control system, patrol system, attendance system, consumption system, parking lot management system. All systems can be operated with IC cards and ID proximity cards, which can easily realize all-in-one cards. The entire system can be implemented at one time, or designed to be implemented step by step according to customer needs, and can also be tailored to customers’ special needs.
Chapter 2 Project Assumptions
Party A is planning a company base consisting of a complex of buildings. There are three entrances and exits in the base. Among them, there are two exits for managing the entry and exit of vehicles, and one entrance and exit for the management personnel. Now it is necessary to plan, design and construct the parking lot management system in the base according to the needs of Party A.
The parking lot management in the base requires the following functions:
1. Apply two-in-two-out networked parking lot management system to achieve parking lot management requirements;
2. Centralized management of internal vehicle users and uniformly issue access cards;
3. Realize remote identification (5-8 meters) control for entering and exiting vehicles, that is, vehicle entrance and exit, the system can sense the arrival of the vehicle at 5-8 meters;
4. Adopting mixed-in and mixed-out non-stop management, vehicles can enter from any entrance and leave from any exit of the parking lot;
5. Manage and control the entry and exit of personnel;
6. Capture images when entering and exiting vehicles, and compare images when leaving the parking lot. If the images are legal, let them go;
7. Control illegal cards, invalid cards, and sneak back cards, and deal with them accordingly;
a) Illegal card: If it is not a card of the parking lot system, it will not respond and warn;
b) Invalid card: Although it is a card in this parking lot system, it is invalid due to some reasons, such as invalid card, invalid card, expired card, card that has been reported as lost;
c) Sneak-back card: There is no entry or exit record, for example, there is no record after the car exits due to special circumstances, and a warning signal will be generated when it returns again.
Chapter 3 User Analysis
The previous manual management not only consumes a lot of manpower, material resources and financial resources, but also cannot improve work efficiency in a practical sense. Due to the large number of personnel entering and exiting the base, the entry of unemployed personnel is difficult to control, and the safety of the base cannot be guaranteed. Often the occurrence of public security cases cannot be controlled in advance, and the security guards cannot identify all personnel on the base; parking lot management uses time cards or parking cards to write cards and enter temporary vehicles for users living in the base every time Complexity, the loss of vehicles in the base; manual settlement of internal consumption in the base, which often creates troubles for counterfeit banknotes, change, financial management, etc.; management like this not only causes a great waste of human resources, increases management workload, but also makes it difficult Ensure the security of information collection. In response to this backward management model, we adopt a two-in-two-out internally managed parking lot scheme based on the actual situation of the base. Users can enter and exit each parking lot with only a smart card, and can also output relevant materials, documents or documents according to requirements. Report.
According to our company’s software engineers, construction engineers and businessmen, they conducted surveys on the map paper of the Hangzhou Huawei base, discussed and analyzed the parking lot project. The summary analysis is as follows:
1. Each person in the entire system can use only one card to complete the function of entering and exiting any parking lot;
2. The project needs to build a parking lot with two entrances and exits. They are Linxi Entrance (hereinafter referred to as No. 1), Linnan Entrance (hereinafter referred to as No. 2 Junction) and the personnel entrance in the middle of the two lanes.
3. The number is the main entrance, and the left and right lanes are each 6M. There is a security guard box on the left and right lanes. The vehicle enters and exits with a valid internal card, and no image comparison is performed.
4. Gate 1 is the auxiliary entrance, and the security booth is embedded in the wall. Vehicles enter and exit with a valid internal card, and image comparison is required;
No. 5 and No. 8 intersections are the entrances for vehicles in the loading and unloading area, and the main supply vehicles enter the underground garage. Vehicles enter and exit with a valid internal card, and image comparison is required;
6. The faculty entrance is the passage between the underground garage and the ground parking lot. Vehicles enter and exit with a valid internal card, and image comparison is required;
7. The parking lot software management system manages the vehicles entering and exiting the company and controls the parking spaces. If the parking spaces in the underground garage are full, the words “Full” will be displayed, and the entry function will no longer be provided. It only refers to the underground garage. Internal vehicles can still be parked in the ground parking lot with a valid internal card.
8. Internal vehicles shall be handled with internal cards, and legal cards shall not be parked for management.
9. The system alarms when using illegal cards or encountering damages;
10. The system has good scalability and can be connected to monitoring equipment such as cameras, smoke probes, infrared probes, and temperature probes;

Chapter 5 Solution
Program narrative
The parking lot computer charging management system is a general term for the modern parking lot vehicle charging and equipment automation management. It is a high-tech mechatronics product that puts the parking lot under computer management. Contains CNC, electronic, mechanical, and multimedia technologies.
solution
The system base parking lot management system needs to manage the internal vehicle users. According to user demand analysis and on-site inspection, it is planned to adopt a networked four-in and four-out internally managed parking system for management. The specific solutions are as follows:
1. The management center installs the parking lot system database system and application programs;
2. Carry out the registration, distribution and card issuance of internal vehicles;
3. Install a 5-8m long-distance card reader at the front of the parking lot, so that the vehicle is detected by the system at 5-8m and sent to the industrial computer for processing;
4. The image comparison system is installed at intersection No. 1, intersection No. 8 and faculty entrance to capture images when vehicles enter and exit. When the vehicles leave the parking lot, the security will compare the images, such as vehicle number, vehicle type, and body color. After that, the release operation is carried out.
5. At the No. 4 intersection, there is one lane each with a width of about 6M, and each lane is equipped with two opposite barriers. A total of four barriers are required. The image comparison of passing vehicles is not performed;
Vehicle management solutions:
Vehicles inside the base are managed to enter the base without stopping. The internal vehicles first go to the management center to collect the card, and the vehicles can pass through the base during the legal use period. When the vehicle enters the base, the long-distance card reader detects the card and captures the picture of the vehicle when it enters the field. If a valid card in the vehicle is sensed, the system will prompt a welcome message, and a green light will show that it is safe to pass, and the barrier will be activated automatically.
When the vehicle passes safely, close the barriers and record the entry of the vehicle (time, entrance, owner’s name, vehicle information, etc.) into the computer database. When the vehicle leaves the base, the remote card reader will detect the card. If it senses that there is a valid card in the vehicle and the images match, the parking lot security will open the barrier. When the vehicle passes the barrier safely, the barrier will be automatically released. And save the vehicle out of the base information record.
Special vehicles entering the base, such as: public security, fire, hospital, emergency repair and other vehicles entering the base, can be released by the security personnel.
Admission solution:
1. The vehicle enters the field according to the state of the full position display screen, and enters the entrance slowly after entering the deceleration slope;
2. When the vehicle presses down on the ground, the camera captures a picture of the vehicle entering the venue. If the car passes quickly, it can be judged to be following the car (that is, the vehicle in front has a legal card, and the vehicle behind is very close to the car in front), the warning light works, and at the same time the remote card reader starts to detect the card. There are three predictable situations during the period:
a) If there is a card in the car, go to the next step;
b) If there is no card in the car, the warning light will warn and the traffic light will be red;
3. The card reader recognizes the card in the car and sends the data to the industrial computer through the control host. The system judges according to the card signal. The following cards are regarded as invalid cards and an alarm is forced:
a) Illegal card: a card that is not from the company, although the internal code is read by the card reader, it is not the card from the company;
b) Invalid card: Although it is a card of this unit, it is invalid due to some reasons, such as expiration, cancellation, loss, etc., the system considers it invalid;
c) Sneak-back card: This is a unique function of this system. For example, after the user enters the venue, there is no induction when he leaves for some special reason, and when he enters the parking lot again, it will be regarded as a sneak-back card;
4. If it is a valid card, the system traffic light is on, indicating that it can be passed.
5. The industrial computer saves this operation record computer, and subtracts the total number of parking spaces and subtracts 1. If the total number of parking spaces in the parking lot is 0 (that is, there is no parking space available for parking), the system full-seat sign is displayed as a light.
6. The computer automatically opens the barriers, and the system enters the anti-smashing detection stage;
a) The vehicle has passed the gate: when the barrier is lowered, the green light in the traffic lights goes out;
b) The vehicle has not passed the gate: the system timings, if it times out, the warning light will warn and the traffic light will be red.
Appearance solution:
1. The vehicle enters the exit;
2. When the vehicle presses down on the ground, the camera captures a picture of the vehicle entering the venue. If the car passes quickly, it can be judged to be following the car (that is, the vehicle in front has a legal card, and the vehicle behind is very close to the car in front), the warning light works, and at the same time the remote card reader starts to detect the card.There are three predictable situations during the period
a) If there is a card in the car, go to the next step;
b) If there is no card in the car, the warning light will warn and the traffic light will be red;
3. The card reader recognizes the card in the car and sends the data to the industrial computer through the control host. The system judges according to the card signal. The following cards are regarded as invalid cards and an alarm is forced:
a) Illegal card: a card that is not from the company, although the internal code is read by the card reader, it is not the card from the company;
b) Invalid card: Although it is a card of this unit, it is invalid due to some reasons, such as expiration, cancellation, loss, etc., the system considers it invalid;
c) Sneak-back card: This is a unique function of this system. For example, after the user leaves the field, there is no induction when he leaves for some special reason. When leaving the parking lot, it will be regarded as a sneak-back card;
4. If it is a valid card, enter the image comparison stage. The system compares the entrance and exit pictures of the car. If the car number, body color, and car model match, the system’s traffic lights will be on, indicating that it can pass. Otherwise, the alarm will be reported and handled manually.
5. The industrial computer saves this operation record on the computer, and subtracts the total number of parking spaces and adds 1 to it. If the parking lot full-seat sign is on, turn off the full-seat indicator.
6. The barriers are opened by manual point control, and the system enters the anti-smashing detection stage;
a) The vehicle has passed the gate: when the barrier is lowered, the green light in the traffic lights goes out;
b) The vehicle has not passed the gate: the system timings, if it times out, the warning light will warn and the traffic light will be red.
