Some Problems and Solutions in the Installation and Commissioning of Video Parking Space Guidance an

With the rapid increase of car ownership, the contradiction between urban cars and parking spaces has become increasingly prominent. In a city with an inch of land and an inch of money, reducing personnel and increasing parking facilities have become the main means to alleviate the pressure of urban parking. When the owner enters the parking lot, he can't find an empty parking space, and when he returns, he can't find his own parking space. What a terrible thing. The emergence of video parking space guidance system has greatly improved this problem and saved a lot of time for car owners. At present, the traditional car search system is the ultrasonic parking space guidance system, and the car search system is the card swiping positioning car search system, which is two independent systems and can not achieve accuracy. The video parking space search system solves this problem, but sometimes some problems may occur during the installation and commissioning of the video parking space search system. How to solve them, Let's look at the following: 1. Camera problem 1. The lamp does not light up after the camera is powered on. Measure the camera voltage to check whether the connection of the power line is open circuit; Check whether the power supply in the node controller is 24V (the terminal voltage of 12V power supply will be low); Log in to the camera using the device search tool or via IP. If you cannot search or log in, you can determine that the camera function is damaged; Conversely, the camera indicator may be damaged. 2. After the camera is connected to the gateway, set and save the problem camera identification area, number of monitored parking spaces and parking space number through the camera IP login setting; Check whether there is parking space and parking number information in the camera information in the gateway database. If not, it needs to be added manually (modify the database file). The file path is zoneservice / zonedata / zone.script 3. The gateway is connected to the camera, and the camera IP is repeatedly turned off. The gateway automatically assigns the IP function zoneservice / appconfig.properties, Modify the camera IP through the device search tool. 4. The camera indicator shows an error. Enter the setting through the camera IP to view the recognition area (the license plate is in the recognition area); Enter the setting through the camera IP to check whether the camera indicator is set correctly; Confirm whether the light source at the installation position of the camera is sufficient and not dim. II. Parking space screen problem 1. The display of parking space screen is wrong, missing or redundant. Determine the damaged parts (control panel and LED screen) by replacing parts, and replace parts. 2. If the gateway fails to search the parking space screen or displays offline, check whether the gateway turns on the automatic search device function, zoneservice / appconfig.properties; Check whether the network cable and interface between parking space screen and node controller are normal; Restart the tcp-485 converter of the parking space screen (installed in the parking space screen). 3. The gateway finds that the parking space screen cannot be distinguished (the IP and number are the same) and checks the dialing code of the tcp-485 converter corresponding to the screen. It is required that the dialing code of each converter is unique; Check whether the gateway turns on the automatic IP assignment function, zoneservice / appconfig.properties; When the gateway automatically assigns duplicate IP, you can modify the duplicate IP by modifying the database (video_ip attribute in public_zone_log table).
