Problems solved by technology
[0002] Existing electric telescopic doors can be roughly divided into guide rail electric telescopic doors and trackless electric telescopic doors, and as electric telescopic doors for guide rail navigation, no matter whether they use single or double rails, they need to be measured, excavated and laid rails, which is not only troublesome to install, It also increases the cost and affects the leveling of the road. What's more, the guide rail electric telescopic door produces friction due to deviation correction during the specific use process, which not only affects its reliability and service life, but also produces noise pollution to the environment; although the existing The trackless electric telescopic door does not need to lay open-air steel rails, but it still needs to lay invisible track identification objects or devices under the ground, such as magnets, metals, closed-circuit wires, etc. It also requires precise measurement, excavation, laying, and filling of the installation site. Strictly speaking, the use of such an induction structure is not a real trackless telescopic door, not to mention, because the corresponding sensor is too close to the ground and easily damaged, which affects the reliability of the trackless telescopic door and service life

Embodiment Construction
[0014] A geomagnetic navigation system for trackless electric retractable doors. The electronic compass uses two independent magnetoresistive sensors that are perpendicular to each other, which can obtain the components of the geomagnetism along its X-axis and Y-axis directions. The voltage signals of the two direction components are simulated The signal amplifier amplifies, AD conversion and corresponding processing, and then synthesizes the geomagnetic direction data information, and sends it to the main control CPU. The main control CPU reads the obtained direction information and stores it in the non-volatile memory when the system is initialized. Comparing the reference direction data with the reference direction data to generate the correction data, and then controlling the rotation of the left and right motors, accompanied by the relevant instructions of the indicator signal output unit, the relevant control signals can be input through the keyboard input unit, so as to r...

An earth-magnetism navigation system of trackless motor-driven telescopic door comprises electronic compass, sequence-connected analog signal amplifier and AD conversion as well as system information access unit, external expansion EEPROM, master control CPU, motor set connected to CPU, indication signal output unit and keyboard input unit for controlling left and right motors to rotate to realize error-correction automatically and to make said telescopic door travel along set direction automatically.
Description
technical field [0001] The invention relates to a trackless electric telescopic door, in particular, it relates to the integration of automatic navigation, automatic control and anti-interference functions, through the navigation of the geomagnetic field signal, the real sense of the trackless is realized, and the use is stable, the installation is convenient, and the reliability is high. A geomagnetic navigation system for trackless electric telescopic doors with advanced technology and high degree of automation. Background technique [0002] Existing electric telescopic doors can be roughly divided into guide rail electric telescopic doors and trackless electric telescopic doors, and as electric telescopic doors for guide rail navigation, no matter whether they use single or double rails, they need to be measured, excavated and laid rails, which is not only troublesome to install, It also increases the cost and affects the leveling of the road. What's more, the guide rail ...
