Description
Technical Field
[0001] The present invention belongs to the technical field of intelligent switches, and in particular relates to an explosion-proof intelligent switch and an installation device thereof. Background Art
[0002] An intelligent switch is a unit that uses a control board and electronic components, combined with programming, to achieve intelligent on / off control of a circuit. This on / off control, also known as bang-bang control, is used in many household appliances and lighting fixtures due to its simplicity and ease of implementation. However, conventional on / off control cannot meet the demands for improved control accuracy and energy conservation. Within a control cycle, the controlled variable has only two states: either on, with a fixed constant value, or off, with the controlled variable at zero. This fixed control mode lacks the characteristics of manual on / off control. Manual on / off control requires a human to select different control strategies based on the error and its changing trend. For example, within a control cycle T, the timing of the controlled variable output can be adjusted as needed. This type of on / off control, which relies on human knowledge and experience and selects different control strategies based on a specific pattern, such as the actual error variation pattern and the inertia, pure hysteresis, and disturbance characteristics of the controlled object (or process), is called intelligent on / off control.
[0003] The authorization publication number "CN206961749U" records "an explosion-proof intelligent switch, including an explosion-proof end cover, an explosion-proof shell, a sensing probe and a sensing module; the explosion-proof end cover is fixedly connected to the explosion-proof shell, and a mounting hole is provided on the explosion-proof end cover. The sensing probe is arranged on the mounting hole and is electrically connected to the sensing module arranged inside the explosion-proof shell. The explosion-proof shell is also provided with a wiring hole, and the cable is electrically connected to the sensing module through the wiring hole. The sensing module is also provided with a relay, and the sensing module outputs a relay control signal according to the sensing signal of the sensing probe to control the on / off of the power supply of the relay coil; the effect is: the explosion-proof intelligent switch proposed by the utility model does not require direct contact between the human body and the switch, thereby eliminating personal safety accidents caused by aging of the switch circuit and leakage."
[0004] The above patent can improve the safety of the switch by preventing direct contact between the human body and the switch. However, the smart switch needs to be operated by bolts during installation, which makes it difficult to disassemble and replace it in an emergency. At the same time, the smart switch installed on site needs to have explosion-proof functions to cope with special environments, so it cannot be used in these occasions, which limits the installation of the smart switch and makes it difficult to replace and maintain it.
