Boundary detection device and method and electronic fence

Abstract

The invention provides a boundary detection device and method. The boundary detection device includes an electronic fence and a directional boundary sensor. The electronic fence includes a conductor and an alternating current generator, and the two ends of the conductor are connected to the alternating current generator. The directional boundary sensor includes a master MCU, an induction coil anda power source, and the master MCU is separately connected to the induction coil and the power source. The boundary detection device can accurately sense the boundary of the conductor with a variablecurrent, and can determine whether the boundary detection device is close to or away from the boundary of the conductor or entering of the boundary range of the conductor or exiting of the boundary range of the conductor or not; and the recognition accuracy is high, the cost is low, low interference is achieved, and remote management can be achieved.

Description

【Technical field】 [0001] The invention relates to a sensing device, in particular to a boundary detection device and an electronic fence. 【Background technique】 [0002] In order to standardize the parking of vehicles, municipal or traffic gates will draw parking lines at suitable parking positions. However, this kind of parking line has no physical constraint function and requires manual supervision. In places where supervision is not in place, the phenomenon of random parking still exists Very serious, disorderly parked vehicles occupy a large amount of public space and bring many safety hazards. [0003] Therefore, people in the industry are working hard to find a mode that can make the public park in the parking line consciously without manual supervision on the spot; however, the first problem that the people in the industry face is how to judge whether the bicycle is in the parking lot when the supervisors are not present. In the stop line? That is, it is judged whet...

Problems solved by technology

The disadvantage of this mode is: because the positioning can only rely on satellite signals, the current GPS positioning system is not accurate enough, and it is easy to cause position drift. In places where urban buildings are relatively dense, the signal positioning will also be inaccurate, resulting in accurate parking. Bicycles cannot be locked, but they can be locked without standard parking, which is obviously contrary to the purpose of standard parking

The disadvantage of this mode is: because the radio frequency and WiFi signal transmission area of ​​the site is a space spherical shape, and its signal strength also directly affects the size of the signal coverage, resulting in a mismatch between the signal range and the parking range

Therefore, a bicycle equipped with a receiver cannot be accurately parked in the designated parking position
