1, two in two out of a common computer; the ground for the charging system (one in and one out); underground garage for monthly users.
Question A: How do two systems enter the computer?
B: How to set the software?
Answer A: The first two system controllers are connected in parallel and connected to the computer through a communication converter. The ID addresses of the two system controllers are 01 and 02, respectively.
B: Using the PARK90 software, set it at the client:
Parking → crossing setting → + → crossing setting table
No. 1 controller entrance setting: The card address is set to 01-1, the door opening address is set to 01-1, and the entrance and exit mark is marked as “√â€.
Export settings: card address is set to 012-6, open address is set to 01-2.
No. 2 controller entrance settings: address card is set to 02-1, open address is set to 02-1, the entrance and exit mark "打".
Export settings: Swipe address is set to 02-6, open address is set to 02-2.
You can.
Â
2, the software is set to "non-repeated access", but repeated credit card can still enter, out of the car. Reset after setting.
A: The reason for this is caused by adding a card to the controller. Please refer to the fifth item to check the system's card-adding method and then check whether this function on the software is wrong! (Please add the card to the software. Do not Add a card to the controller.)
3, in the debugging stage, the computer can not communicate with the control
A: This problem is a problem that often arises during the initial installation and use of the system. For this problem, it is recommended that during the initial commissioning of the on-site system, all devices should not be connected and tested. Instead, they should be connected one by one, and then judged. Problems that may arise will reduce the scope of the problem as much as possible. Common problems:
1): No accessibility
In the debugging stage, especially when the distance between equipments is far away, this situation often occurs. To eliminate this problem, the basic method is:
1 Remove the device-side, 485-card communication cable from the device and the 485 card, and then short-circuit the device
2 Measure with a multimeter on the computer side to determine if it is on.
2): wrong connection
The wrong connection to the line contains the following two meanings
1 misuse other lines as communication lines (such as intercom, etc.)
2 Reverse the 485 A and B lines
For 485 communication, you must follow A to A, B to B principles. Please carefully check the correspondence between the device and the 485 card.
4, the computer can carry out one-to-one communication with each device in the system, but can not communicate after all devices are connected?
A: Most of the problems are in the wiring of the system, and the wiring and wiring are not performed according to the requirements of the 485 bus system. For the bus-type network, all the devices must be connected in a hand-in-hand manner, but not in star or fish. Bone-shaped cloth, wiring, only re-wiring.
5. The led display shows that the number of parking spaces is slow. After the vehicle is swiped, the software shows that the parking space has been reduced by one, and the led display remains unchanged. Ten minutes have not been displayed normally during the test.
A: The parking space display of the led display is relatively slow. Please reduce the display content of the display and shorten the scrolling frequency of the content. For example: Only show time and parking spaces.
6. Swipe the card at the entrance with a "click" sound. No voice prompts, no shots.
Answer: The phenomenon is that the system controller either did not receive the card reading signal or did not issue an instruction to the computer and the barricade after receiving the card reading signal, causing no voice prompts and barriers to stand up. “嘀†is the sound of the reader, please observe the system controller at this time and listen to the relay to see if the sound and the corresponding indicator light are on. Please check this item carefully. The two system controllers are compared and interchanged. Look at the effect! To determine the cause, if the system controller problem, you can replace the solution, please be sure, or replace the device can not solve the problem! One to check the system controller, one to check the card reader to the system controller connection.
7. When the parking space is full, no voice prompts "The parking space is full", and the credit card is still playing. The card is added to the controller, not the software.
A: When the parking space is full, the software does not have voice prompts. When the card is added on the controller: As long as the card is swiped, the controller will open the barrier at any time, and all the controls will be completed by the controller. After the vehicle is full, it will still swipe the rod. This item is mainly used for testing the hardware when the computer is not connected. Please debug the hardware, delete the card on the controller, and then add a card on the software to allow the software to complete the control of the system, to avoid the controller to complete the control of the system.
8. How does the signal line of the parking management system connect to the gate?
Answer: The two signal lines coming out of the ticket box are directly connected to the “common†and “riser†signal terminals on the gate control board. The customer is often mistaken for the “485 serial communication interface†of the converter main board connected to the computer. This is wrong.
9, in use, the computer suddenly can not communicate with the lower computer
A: Most of the problems are caused by damage to a device in the system.
When you suspect the device, touch the 485 communication chip by hand. If it is hot, it indicates that it is damaged.
