According to the requirements of a community in Nanhu, Wuhan Bozi Intelligent Technology Co., Ltd. is formulating the project plan for the parking lot system of the community. 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.
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 plan is 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 staff entrance respectively, and images are captured when the vehicle enters and exits. When the vehicle leaves the parking lot, the security will perform image comparison, such as vehicle number, vehicle type, and body color contrast 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 barrier gates, a total of four barriers are required, and no image comparison work is performed for passing vehicles;
Vehicle management plan:
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 a 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 indicate 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, name of the vehicle owner, 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 fighting, hospitals, emergency repairs and other vehicles entering the base, can be released by security personnel.
Admission solution:
1. The vehicle enters the venue according to the state of the full 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 as following (that is, the vehicle in front has a legal card, and the vehicle behind is very close to the vehicle 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 the company, 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 will be 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 the time is over, 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 as following (that is, the vehicle in front has a legal card, and the vehicle behind is very close to the vehicle 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 the company, 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 leaving 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. For example, if the car number, body color, and car model match, the system 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. Open the barriers 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 the time is over, the warning light will warn and the traffic light will be red.
