The disadvantages of manual counting exist:
1. It is necessary to count and check whether the vehicle is qualified or not. It will be easy to run into trouble when the vehicle is in full operation.
2. The criteria for inspection of vehicles by workers are very different, and there are no records available for inquiries, which may easily lead to disputes.
3. The environment of the sand mining area and the mining area is very bad, and it is difficult for the staff to check the vehicle outdoors for a long time;
4. It is difficult to increase the traffic speed of the vehicles. Re-starting the vehicles not only greatly delays the transportation time but also consumes fuel and discharges more exhaust pollution.
In response to this situation, the company's automatic attendance counting system developed by Jiaoan Company adopts digital technology, display technology, control technology, video capture monitoring technology, and international advanced RFID technology, combined with computer software technology, to transport vehicles entering and leaving the project site.

3LED display system shows related content: "XX number XX in and out of the car", super bright LED display system shows the number of vehicle statistics: super bright system will not be affected by the weather, even when the sun is very large, you can see The contents of the display screen are clear for the driver and related personnel to view, making the system work intuitive and user-friendly.
4 software management system for real-time registration and storage of vehicle information for drivers and managers to check and print data.
5 Real-time surveillance video monitoring of passing vehicles, but also to see whether each vehicle is full, whether it is empty, as well as whether the return of the vehicle is sticky, etc., real-time monitoring video automatically save, easy management Personnel check at any time.
Third, functional characteristics:
1) When the vehicle passes through, Bluetooth remote reader automatically obtains the vehicle number, and does not stop to read the card;
2) When the vehicle passes by, automatically records and displays the number of the vehicle and the number of passes on the LED screen (optional);
3) Each car takes a high-definition photo (1600x1200) million HD pictures, which can clearly distinguish vehicle characteristics and loading capacity;
4) Flash light is automatically triggered at night or when lighting is insufficient (optional);
5) The photo data can be saved in a USB flash drive, and the U disk is replaced regularly to obtain data (self-provided);
6) Support networking (wired, WIFI, 3G) to transfer photos without manual access to the site (optional);
7) The system power consumption is low, battery + solar power supply (self-provided) can be used;
8) The software provides statistical functions according to days, months and years; vehicle statistics can be selected (freely provided);
9) High reliability, long-term continuous operation in low temperature and high temperature environments;
10) Ordinary credit card counting system is recorded in words; we use photos to record, and the statistical results are more intuitive and persuasive;
11) Integrated design, no computer, power-saving effect, to achieve offline counting function.
Fourth, the system features:
1, print output function: statistical results can be printed out in Excel file format; for the software can not export their own output to change the report, and can set the card to automatically print vehicle card number, credit card time, and other information; support for ordinary printers and thermal paper or Dot matrix printer;
2. Real-time display function: When the vehicle reads the card through the intersection, the roadside display immediately shows the number of the swiped vehicle and the first few times;
3, no parking card function: the vehicle automatically read the card after a long distance crossing, the driver does not have to get off or manually swipe, greatly improving the efficiency of the vehicle traffic;
4. Voice broadcast function: The success of the card reading system automatically broadcasts the card reading success, and the standard Chinese prompts such as: "No. 001 car number several times", to facilitate on-duty personnel and drivers in real-time interpretation of the card situation 5, a powerful signal penetration function : The reading distance can be adjusted from 3 to 15 meters. The reading signal can penetrate the car's explosion-proof insulation film, and can also penetrate the tempered glass without any attenuation;
6, fixed-point capture image real-time video function: the vehicle to read the card system immediately fixed-point capture images and automatically save, and the other way camera real-time video and save for ready to query.
Fifth, the customization function:
1) Welcome words can be set. When the system is started, set welcome words are automatically displayed on the screen;
2) It is possible to set license plate numbers, vehicle numbers or names corresponding to different card numbers to support Chinese;
3) It is possible to set the minimum repetitive credit card interval allowed to prevent the same card from being repeatedly swiped in a short time;
working principle:
Pictures of passing vehicles are automatically taken and the time, number, vehicle appearance, loading capacity and license plate of each vehicle are accurately recorded. The photos are stored in a USB flash drive for easy retrieval at any time. The date and time are automatically superimposed on the photo. The name of the photo contains the elapsed time and number. The software can conveniently count and query the number of passes per day, the passing time of each car, and the photos when passed.
Each car that needs attendance puts a Bluetooth card. When the vehicle passes through the monitoring point, the card reader automatically reads out the card number of the Bluetooth card on the car and sends the card number to the capture camera. The camera automatically takes pictures after receiving the card number, and records. Time and vehicle number, at the same time the number of the vehicle and the number of passed to the LED display screen, photos and vehicle information can be stored in the U disk, SD card, regularly send people to extract, you can also automatically return through the network. The system has an automatic fault detection function. If the U or SD card is not plugged in or not plugged in, an error message will be automatically displayed on the display. While taking a picture, the camera controls the flash to indicate that the driver has taken a photo. (Note: In order to prevent repetitive swiping of the same car, you can set “repetition swiping time limit†so that if the same car has been swiped several times in a short time, the system will only record valid attendance information once, and the duplicated swiping records will be separately identified. Come out and check it out.)
The pH value suitable for ornamental fish life is 6-9;
When the pH value of water is greater than 8.0 or less than 7.0, most of the disinfectant in the pool water exists in the form of hypochlorous acid, and the hypochlorite root (residual chlorine) only accounts for a small part, which will undoubtedly greatly reduce the activity of disinfectant in the water, and then affect the effect of algae killing and sterilization.
Soil pH value is one of the basic properties of soil, and it is also one of the important factors affecting soil fertility.
The pH value of all kinds of soils in China varies greatly, most of which range from 4.5 to 9.
It directly affects the form, transformation and availability of soil nutrients.
Soil pH value is closely related to the analytical methods and results of many projects. When reviewing the results of these projects, it is often necessary to refer to the value of soil pH value.
For the soil with low pH value, acid damage and aluminum toxicity may be the limiting factors of crop yield, so it is necessary to consider applying lime to improve the soil.
The national standard soil pH value is 4.5-9.
