Companies with Better License Plate Recognition - License Plate Recognition System - Tigerwong

The advantages of the license plate recognition system are detachable in sections and detachable poles: multi section detachable flagpole. Convenient transportation, welding and on-site assembly; High degree of product standardization; The plug-in connection ensures that the winding is not bent, and the appearance is tall and powerful. Of course, the tapered integrated flagpole can also be selected according to customer requirements, which can be freely selected by users. For example, all flagpoles used in the Universiade are tapered integrated flagpoles. Collar: the flagpole crown is equipped with a guide hole fit and tension knot, which can make the flagpole and the pole have no contact and always be in balance, there is no friction noise between the poles, and the crown rotates more flexibly along the wind, making the flagpole as a whole tall and spectacular.

When the speed changes greatly, the torque is constant. Under the same power and speed, compared with other common motors, its starting impulse current and volume are small. Variable frequency motor: Nd-Fe-B rare earth permanent magnet synchronous variable frequency speed regulation self coding motor. The speed of the motor can accurately follow the change of the input frequency. However, its torque is 2 to 3 times that of other motors, and the working current of the motor will not rise when the motor is locked for a long time.Integrated movement: the movement integrates four parts: worm gear reducer, torque converter, main shaft support and main bracket. Using 45# steel integral precision casting, it is processed by large CNC machining center at one time, which greatly reduces the number of internal parts. Cut the ground 10cm deep, when wiring the ground induction coil. 2x0.8m square groove, with four corners cut into 45 degree bevel. Place the ground induction coil (1 mm2) in a circle, with a total of 6-8 layers. The coil must be pressed between each layer. Do not have connectors in the coil.The output end of the ground induction coil is twisted to the track gate. And the distance shall be as short as possible. Seal the groove with dry cement after connection. Note: for the high-temperature copper conductor with the cross-sectional area of the ground induction coil of 0.51.5 mm2, the cross-sectional area of the wire does not have a great impact on the induction strength. Precautions in the process of gate device: the gate equipment must be operated according to the wiring diagram when wiring.

After connecting the line, first test whether the ground sense is normal. When the ground sense red light flashes, put an iron plate above the coil. When the red light is on for a long time, take away the iron plate, and the automatic falling of the gate is normal. After the induction coil is wound and energized, the coil will oscillate at low frequency. When metal enters the coil, which license plate recognition system is good? Promise to keep promise. The magnetic line of force is weakened by the affected magnetic field, picked up by the magnetoelectric sensor, and takes corresponding action. The induction strength of the induction coil is closely related to the number of turns and the shape of the coil.

Too many coil turns, large input reactance, resulting in open circuit; The number of turns is too small and the input reactance is small, resulting in short circuit. These two conditions will make the work indicator of the magnetoelectric sensor flash quickly. The general number of turns is 68. The sensor always detects a moving object and opens the door, which is the cost of the road gate in the professional community. Such as heavy rain, streamers, insects and other abnormal moving objects. Reason why the door leaf keeps opening and closing: the induction or access control device cannot recognize, and no signal is transmitted to.

Check whether the lifting wheel is derailed and the door body is dragged to the ground. Check whether there are sundries stuck on the door body, lifting pulley and belt. Cause of door leaf immobility: check whether the power supply is powered off. Rare faults and solutions: if damage is found, repair or replace it in time. Let me discuss what will happen in the electric telescopic door market. Hardware maintenance: regularly check all kinds of hardware accessories of telescopic door.Hardware used for a long time can be coated with a little fire wax oil or drip some engine oil to prevent corrosion: try to prevent acidic and alkaline chemicals from contacting the surface of aluminum alloy telescopic door. Manual flag raising is suitable for flagpoles below 15 meters. Electric flag raising is suitable for 12m 30m, manual, electric and pneumatic application places and methods. If it is over 25 meters, it is good to use two national flags to raise the flag. Electric flag raising usually includes manual button, electric button and remote control electric.

In order to ensure the seriousness of flag raising, manual button shall be used for flag raising on the right track. The flag raising hand shall face forward and press the button on the front of the left hand (the eyes only look at the front without looking at the button, which is the same as flag raising). Remote control can be used for experimental flag raising. The pneumatic flagpole is usually suitable for indoor air without blowing to the center. For example, the on-site pneumatic flagpole with TV station and opening ceremony or closing ceremony in the gymnasium does not need to be installed downwind. For the selection of ball crown, the government, enterprises and institutions can choose round ball or flat top ball.

The ball can be plated with titanium gold. Star hotels can choose crown type, gold and silver, and ball crowns of different sizes can be selected according to different heights.
