More than 1,000 days and nights of unremitting efforts, through a series of complex processes such as demonstration, design, installation, testing, and debugging, solved dozens of technical problems. Recently, Shenzhen Huanggang Port Inspection and Quarantine Operation, this indicates that a rigorous inspection and quarantine “electronic port” will soon be built and used at Huanggang Port. The use of this system will greatly improve the efficiency of inspection and quarantine work and speed up customs clearance at the port.
The so-called “electronic gate” means that when the vehicle enters or exits the country, the on-board electronic card can quickly sense the signals of the inspection and quarantine base station, and transmit the relevant information of the electronic card to the base station. The system immediately obtains the vehicle’s transportation company, license plate number, driver’s name, and health According to the information such as the validity period of the certificate, the deduction of fees, and the supervision of inspection and quarantine business processing, the inspection and quarantine department shall promptly implement control, inspection, and issue relevant inspection and quarantine instructions on entry and exit vehicles based on this information, and guide the driver to rely on the platform and handle the inspection and quarantine business. Realize effective channel management.
At present, Huanggang Bureau has installed on-board electronic cards on 158 vehicles entering and exiting Huanggang Port. After a period of trial operation, the inspection and quarantine department has an average reading rate of 99.2% for entry and exit small (passenger) vehicles. The average reading rate of inbound and outbound trucks reached 98.1%, and the time from collecting on-board electronic card information to feeding back the guidance information to the owner was less than 1 second, indicating that the system is operating effectively.
Huanggang Port is currently the largest land port in Asia, with nearly 30,000 vehicles entering and exiting each day. How to speed up customs clearance at the port and effectively supervise entry and exit vehicles, Huanggang Bureau has thought of many ways. After full demonstration, Huanggang Bureau proposed the idea of using high-tech means to establish an “electronic gate” for inspection and quarantine. Since 2005, the bureau has been conducting research, demonstration, and design for this project. Due to objective conditions at the port and various other reasons, the project has not been launched. In September 2007, Huanggang Bureau and Shenzhen Institute of Inspection and Quarantine conducted a large number of investigations, successively investigated more than 20 companies that master wireless technology, and conducted repeated tests and comparisons. It was finally decided to adopt today’s advanced active RFID technology to establish a wireless, independent “electronic gate” that does not depend on other units at the port through multiple base stations, dual frequency bands, and multiple channels.
In order to ensure the reading rate, Huanggang Bureau conducted detailed demonstrations on the number of base stations installed, the reading distance, the development of base station software and on-board electronic card software, the development of base station monitoring software, and the development of on-board electronic cards.
In order to prevent missed reading, Huanggang Bureau set up multiple base stations to ensure the reading rate. A total of 12 base stations have been set up in the entry and exit cargo inspection and small (passenger) vehicle passages. Each base station can independently complete the identification of the entry and exit vehicles, and each is a backup to ensure the read rate of the base station to the vehicle.
In order to ensure effective reading under complex conditions, Huanggang Bureau selects two working frequency bands for the wireless base station and the on-board electronic card for networking. The two frequency bands work at the same time and complement each other. The reading distance can reach up to 300 meters. Can cover the entire Huanggang Port.
The scene environment at Huanggang Port is very complicated. Huanggang Bureau targets the crossing of entry and exit passenger trucks, mixed reading of entry and exit, misjudgment of base stations, vehicle staying overnight, and hundreds of vehicles continuously transmitting signals at the same base station during traffic jams, etc. Various complex situations were analyzed one by one, and the base station software, on-board electronic card software and gate algorithm software were developed throughout the entire process. After more than two months, the related software problems were solved.
In order to prevent base station failures from affecting the reading rate, Huanggang Bureau organized the development of base station monitoring software, which can automatically monitor the operating status of the base station, try to automatically repair and send SMS alarms when there is a problem with the base station, so that the staff can be the first time Rush to the scene to repair the fault to ensure the normal operation of the base station.
In order to ensure the performance of the on-board electronic card, Huanggang Bureau has determined the tolerance of the electronic card under various harsh conditions such as high temperature, rainstorm, typhoon, the durability of the battery, the frequency of the signal emitted by the electronic card, and the type, quantity, and duration of the indicator light. Specific requirements have been made on the lighting time and the type of voice prompts to ensure that vehicles imported into the port supervision zone are automatically guided to go through relevant inspection and quarantine procedures.
At present, the trial operation of the Huanggang port inspection and quarantine “electronic gate” has been basically completed. In the next step, the Huanggang Bureau will put this high-tech scientific research achievement into full use. In the near future, a system that integrates fast customs clearance and strict supervision The electronic port will be built and used at Huanggang Port.
