License Plate Recognition System Maintenance_ Welcome to Consult - Tigerwong

The strong current and weak current parts connecting electrical appliances and electronic components through various cables of the license plate recognition system. The parking lot system belongs to electromechanical equipment. It is recommended to check whether the power supply voltage is 220V from the strong current inspection, that is, one live wire and one zero wire. It is easy to detect with a multimeter, because during construction, there are many three-phase wires, which may be two live wires, and the voltage is 80V. It is very important that almost all of these reasons burn out the electrical equipment, and then check whether the wires are wrongly connected according to the circuit diagram, After checking whether the weak current local communication line, can bus positive and negative level and weak current equipment line are correctly connected, you can power on and test run. The inspection of system equipment line in a parking lot does not need to carry cards. Advantages: convenient operation.

The safety coefficient of the license plate recognition system is slightly higher than that of the disordered keyboard type (the numbers on the keyboard are not fixed and change automatically from time to time). Disadvantages: it can only accommodate three groups of passwords at the same time, which is easy to leak and has poor safety; No access records; Only one-way control. No need to carry cards; Low interest. Ordinary type: it can not only realize various payments such as central charging, magnetic card discount and stored value user payment, but also 4 license plate recognition parking lot management mode is more humanized, which can be managed according to the park. You can also use mobile phone end payment, such as the popular WeChat payment and Alipay payment, and support the setting and query of free and free reasons. The type selection shall be based on the actual project. 7. Fixed column: the column is directly fixed with the road. 6. Movable lifting column: the column and base are locally separated. The main use places, advantages and disadvantages of various columns are different.

It can be stowed when the column does not need to be made. The main purpose of access control system is to prevent loss and prevention, so it must have high reliability. An access control system for the maintenance of isolation piles in Xifeng community. Most of the time of its operation, there may be no alarm, so there is no need for alarm. The probability of alarm is generally very small, but if the alarm system fails within this very small probability, it often means the arrival of disaster.

Therefore, reliability design (redundant design) and reliability management must be implemented in each stage of design, construction and use of access control security system to ensure the high reliability of products and systems. Reliability and selflessly supervise each patrol officer to complete the patrol task according to the predetermined patrol line and time interval. The recording devices of the electronic patrol system are reasonably and scientifically set up in front and back of the house, green belt and walkway of the whole community. The recording device of the license plate recognition system can record the time before the patrol personnel patrol to the device in detail and accurately. It effectively ensures that patrol personnel arrive at any alarm point in the community within the specified time. The third line of defense electronic patrol system, such as military bases, is used in some high-level security applications.

Prisons, etc., need to use anti-terrorism level lifting columns. Compared with the lifting column of general civil grade, the column thickness generally needs to be more than 12mm, while the lifting column of general civil grade is 3-6mm. In addition, the device requirements are also different. The TV monitoring system is installed, including the gate of the residential community, the entrance and exit of the parking lot (garage), the elevator car and the main channel in the community. And implement 24-hour surveillance and video recording.

The personnel of the monitoring center can watch the situation of each channel at any time through the TV picture. Once there is a case, they can provide valuable image evidence materials for the police. The second line of defense TV monitoring system parking lot system integrates inductive smart card technology, computer network, video monitoring, image recognition and disposal and automatic control technology, and is used for the maintenance of lifting road piles in Duyun community. Automatic management of vehicles in the parking lot, including a series of scientific and effective operations such as vehicle identity judgment, access control, automatic license plate recognition, parking space retrieval, parking space guidance, meeting reminder, image display, vehicle model calibration, time calculation, fee collection and verification, voice intercom, automatic card collection (collection) and so on. These functions can be flexibly deleted or added according to the needs of users and the actual situation on site to form luxury, standardized and energy-saving parking lot management systems and vehicle control systems of different scales and levels.
