A Variety of Ground Induction Coil Vehicle Detectors Feel Different Charm - Tigerwong Technology

Ground induction coil vehicle detector is a vehicle detector based on the principle of electromagnetic induction. It usually embeds a ring coil under the road subgrade of the same lane and supplies a certain working current as a sensor. When the vehicle passes through or stops on the coil, the iron on the vehicle itself will change the magnetic flux in the coil, causing the change of the inductance of the coil circuit. The detector judges the state of passing vehicles by detecting the change of the inductance. Many people think that the ground coil vehicle detector is just a small thing, nothing strange. Then, tigerwong technology, as a leader in the domestic parking industry, will bring you a taste of different ground coil vehicle detectors. Shenzhen tigerwong Technology Co., Ltd. started from the card machine and ground sense at the beginning. In 2001, the first card machine in China was developed and produced by our company. The card machines in the whole industry are basically made according to the interface definition of our company. In 2002, it began to develop the ground sense. After industrialized production and more than 10 years of precipitation, In the parking lot industry, tigerwong is basically mentioned as long as the card machine and ground sense are mentioned. After more than ten years of technical precipitation, our company has developed five categories of products: parking lot charging system, parking space guidance system, location guidance system, reverse vehicle search system and traffic light control system. Let's first look at the vehicle detector. The vehicle inspection of our company is: ring induction coil vehicle detector, commonly known as ground induction, which is an embedded detection system. 1. It is mainly used in parking lot, highway traffic toll station and signal light control system. 2. Its working principle is that the vehicle detects the condition of the vehicle by changing the inductance of the coil magnetic field through the annular coil buried on the ground, which is processed by the sensor carried by the ground sensing ability and uploaded to the control system, so as to meet the needs of traffic control. 3. Function: combined with the road gate to realize the automatic closing of anti smashing vehicle and vehicle running; Combined with the card machine to realize one card for one vehicle and the card reading of the crimping ring; Combined with video acquisition equipment to realize pressure coil capture; The two-way ground sense can also realize the function of judging the driving direction of the vehicle. 4. Our company has developed in the field of ground sense for more than ten years. There are many large brand companies whose ground sense is OEM in our company. At present, according to the needs of different levels and industries, our company has the following types of ground sense: one way: tld110, pd132, tld500, one coil tld110: the output mode is two relays, presence and pulse output, Pulse output mode can be set, no delay output function, 2-level sensitivity adjustable, frequency adjustable, and reaction time of 100ms. It is the most widely used pd132 in the market: compared with 110, 132 has more levels of frequency adjustment, sensitivity improvement function and 10 minute effective existence time. The response time is 10ms tld500: the output mode is 4 relays, existence and pulse output. The pulse output mode can be set, with 0 4.5s output delay, 0 9 levels of sensitivity and 4 levels of frequency, The reaction time is 20ms. Tld110 pd132 can meet the general functional requirements of the system. It is the most used ground sense in the market. Tld5oo is generally used in highways, places with harsh environment or places with more detection trucks. II. Two way: pd232, tld600, two coils pd232: Based on tld110, there is an additional direction discrimination function, which requires two coils to work. After determining the direction, the vehicle direction signal is output when leaving the first coil; Tld600: compared with tld500, if two coils are used, the function of vehicle driving direction discrimination can be realized, and one coil can also be used for single-way ground sensing, without the function of output delay. The main function of two-way ground sensor is to judge the driving direction of the vehicle through two buried coils. It is generally used in the place where two channels judge the direction. Compared with pd232 vehicle inspection, the output mode after determining the direction can be set by dialing the code. Tigerwong parking management system has been inherited for many years!
