Problems solved by technology

However, the traditional magnetic sensitive switch can only detect the two states of on and off because the magnetic sensitive element itself is used. Generally, a single switch can only be used for a single basic I / O switch operation, and it cannot realize the control equipment to perform various functions. However, the application of multiple magnetic sensitive switches on the same device is limited by the non-directional characteristics of the magnetic field, and there is a problem of misoperation caused by magnetic mutual interference, and the required operation cannot be accurately realized.

Abstract

The invention relates to a coding control method based on magnetic sensitivity and a switching system. Instruction codes of response signal combinations are set through different combinations of frequencies and / or durations of an external magnet entering a magnetic sensitive area, the single magnetic sensitive switch controls the equipment to execute various different operations, holes do not needto be formed in the equipment shell, the leakproofness of the equipment shell can be guaranteed to the maximum extent, and the switching system meets the operation requirements of electronic equipment in specific environments such as sandstorm, moisture or underwater.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering safety monitoring, in particular to a magnetic-sensitivity-based coding control method and a switch system. Background technique [0002] In the field of geotechnical engineering safety monitoring, especially in the state control or execution of electronic equipment, data acquisition and communication equipment in outdoor environments, the traditional multi-state or function control of electronic equipment usually uses one or more mechanical switches, touch Switches or switches that require external force to control the working state of the electronic device independently or in combination, such as light touch buttons, membrane switches, etc., but these switches are usually not suitable for electronic devices that require higher sealing levels and isolation settings . In particular, some functional state control operations that are not suitable for opening the housing of the elec...
