1. Vehicle access management in the institution
This article refers to the address: http://
The organs of various organs are important office places, and the number of people and vehicles entering and leaving the compound is not only numerous but also important. There are more vehicles for residents or guests entering and leaving the community. The level of the institution's compound and community not only affects the efficiency of vehicle entry and exit, the safety of vehicle access, but also the civilized image of the institution's compound and community. With the development of China's economic construction industry, the number of car ownership has increased sharply, and the requirements for the vehicle management level of government institutions and communities will become higher and higher. In order to make the vehicle access easy, fast and safe, the access control management is scientific and efficient, the service is high-quality and civilized, and the high-tech products are used to realize the intelligent management of the vehicle. It is an inevitable choice for the institutions, the important halls and the high-grade residential parking lots. Remote identification products are the best choice to achieve this. The vehicle intelligent management system has the following main advantages:
1, the system is fully functional
With automatic identification, intelligent control, alarm prompts, information recording, data communication and query, statistics, analysis and other functions; at the same time, with the convenience of expansion, easy to upgrade features.
2, system performance is stable and reliable
The hardware is strictly screened and rigorously tested, and appropriate backup is left; the software is carefully designed, carefully debugged, and has redundant fault tolerance performance; the system has fast processing speed, high reliability, good stability, low error rate, and data backup and data. Resilience.
3, to achieve normal vehicles without stopping quickly
Using ()--the advantage of long-distance rapid identification, through the automatic identification of vehicle information, database data comparison, road gate railings and automatic control of traffic lights, real-time control of vehicle traffic, to achieve vehicle speed of 20-30km / h Parking in and out; for systems without gates and traffic lights, the speed of entry and exit is above 40 km/h.
4. Strict supervision of vehicles without cards (foreign)
The regulation of cardless (external) vehicles has always been a technical difficulty in RFID vehicle management systems. By integrating other systems and technologies, it is possible to implement effective supervision of external (no card) vehicles by means of computer automatic identification monitoring and manual operation of guards (guards, security guards) to ensure the admission of cardless (external) vehicle information. Supervision of vehicle traffic.
5, to prevent theft of vehicles
Data management of vehicle information in the compound; in addition to setting image capture equipment, adding status information of the vehicle RFID card data area; vehicles with special requirements for security and anti-theft, using vehicle RFID card and dual-card identification of the driver carrying the secondary card Solution; add control functions to the system as needed.
6, easy to use and easy to operate
The user interface is intuitive, image and friendly; the operation steps are simple and clear; the application system provides corresponding "online help".
7, system data security and confidentiality
Access control at the network level, system level and database level; ability to check the user's legal identity and usage rights; data is encrypted.

Second, the highway automatic charge
It is also called non-stop electronic charging. It uses electronic communication and computer technology to realize the charging function. In the whole process, the operator does not directly participate in the charging link, and only needs to supervise and manage the equipment and handle special events.
Each car has its own long-distance identification card that is mounted on the front windshield of the car. The model identification is pre-approved under the static condition of the vehicle and recorded in the identification card corresponding to the license plate number one by one. The data in the identification card can be read by the microwave device several meters away or can be modified. The whole process of charging is handled by electronic communication and computer, without manual intervention, and no parking payment. The cost is the user's advance payment in advance on the card, or in the bank's special account.
The key to non-stop electronic charging is automatic electronic identification and fast communication of vehicles. The entire charging system consists of four parts.
1. Electronic identification card
1. The electronic identification card is an active electronic RF card with a power of about 1/1000 watts. Its memory can be used to store various information including vehicle model, license plate number, and related information of the owner. It is a perfect car. ID card and credit card.
2, the transceiver
The transceiver is a device with a microwave line that establishes high-directional microwave communication with the identification card. It has strong anti-interference performance and fast communication capabilities. France uses European standard 5.8 GHz microwaves and the United States uses 2.5 GHz microwaves. Which standard is adopted when introducing the system in China is directly related to the future national highway toll collection. This is a problem worthy of attention.
3. Microprocessor for communication processing
It interprets the information from the identification card and transmits it to the lane controller, so as to obtain the relevant information of the vehicle and perform corresponding processing, and the data information from the lane controller can be analyzed to make necessary modifications to the data in the identification card. .
4, lane controller
According to the information on the card, it is determined whether the vehicle has normal power to pass, and the validity of the card can be judged, and the corresponding traffic sign can be activated, and a warning can be issued to the owner of the necessary prompt. If a violation of the rules occurs, the capture system can also be driven to conduct illegal forensics.
Before a car with an identification card enters the non-stop toll lane, there will be a sign indicating that it will reduce the speed (less than 50 km/h). When the car passes through the first gantry equipped with a transceiver (also equipped with a camera and an infrared detector), the transceiver and the electronic identification card are mutually confirmed by high frequency microwaves. The transceiver first verifies the validity of the electronic identification card and reads the data calculation fee in the card. If the card cannot be identified (including invalid) or the balance is insufficient, the barrier in front of the gantry will not rise, and the system will issue a warning to the driver to enter the semi-automatic toll lane on the right. If everything is ok, the barrier in front of the gantry rises automatically, and the information in the electronic identification card is modified when the car passes the second gantry equipped with the transceiver, completing the charging process. The capacity of the system that has been opened in foreign countries is 800-1500 vehicles/hour or even higher, and the error is only 10E-6. The non-stop charging system can improve the traffic capacity of the road, shorten the travel time, reduce delays and blockages, and greatly increase the speed of the vehicle when passing through the toll lane.
With the rapid development of expressways, the toll highways built in phases have a trend of networking, which puts a new topic for the toll collection system--the highway toll collection system. Due to different investment channels, the highways that should be networked are artificially divided and independent, and each manages and charges. This increases the number of toll stations, reduces vehicle traffic capacity, and reduces investment efficiency. The expressway network toll collection system can realize the toll collection, branch settlement and centralized management of multiple expressways. The vehicle can be used for one vehicle and one card, one card for the end, and one payment; it can block the charging loopholes to the maximum extent and improve the service level and work of the toll. Efficiency, reduce the work intensity of the toll collectors, facilitate the settlement of charges, and regulate the management of charges. It is a better choice for the use of semi-automatic toll collection systems for connected highways.
In some developed countries such as Europe and the United States, toll stations usually have both semi-automatic toll lanes and non-stop toll lanes, and there are almost no toll stations with only single toll lanes. For a long time to come, semi-automatic charging methods, especially magnetic card (IC card) charging methods, will continue to exist for a long time and play an important role. Of course, when the national highway toll collection is realized in the future, electronic parking without parking is the best choice.
