The patent application for this product has been passed. It uses the interference phenomenon of a ferromagnetic object on the earth's magnetic field environment, and uses a three-dimensional magnetic field environment sensor to detect the presence of a ferromagnetic object through changes in the magnetic field environment around the sensor. It is only sensitive to changes in the Earth's magnetic field environment. It adapts to the development direction of world sensor products and belongs to the category of intelligent sensors. This product is compared with other types of sensors (such as: ground coil detector, wireless magnetic vehicle sensor), because this product adopts dual CPU structure, it has a high degree of intelligence, good stability, strong anti-interference, low failure rate , Easy installation, use, maintenance, low investment, low overall cost, etc. According to the market demand, this product has developed into a series. Currently, there are three models available for users to choose according to different uses, different environments and requirements. This product is small in size (equivalent to a disposable lighter), extremely low power consumption suitable for battery-powered (or solar power) mode, with a switch output, an RS485 network interface. Through the digital output and RS485 network interface, this product has on-site and remote data acquisition and monitoring functions. In addition, through the RS485 network interface, this product also has the ability to remotely set or modify sensor internal parameters (sensitivity level, sensor threshold, zero setting, sensor address, transmission rate, etc.). The shell of this product is made of high-strength aluminum alloy material (internal infusion of epoxy resin). The overall design is based on waterproof requirements. It is used for long-term stable operation in wet or underwater environments. This product has the advantages of small investment, real-time monitoring effect, stable signal transmission, long transmission distance, strong anti-jamming capability, and low maintenance workload (does not require regular battery replacement) compared to sensors of the same type and wireless geomagnetism vehicle.
Second, the main purpose: 1. Intelligent traffic control system (ITS). 2. Parking lot intelligent management system. 3. Automatic control of electric doors, garage doors, warehouse doors and so on. 4. Motor vehicle (mine car) detection, positioning, scheduling, and alarm. 5. Ship detection.
