Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an industrial remote controller having an emergency stop button switch and a power supply switch,

In general, in industrial fields, a wired or wireless industrial remote control is used to remotely control the operation of various hydraulic equipment or special heavy equipment. Especially, heavy equipment such as crane, ladder, and perforator can be moved directly by the person, but in order to reduce the risk when driving and to improve work efficiency, it is often operated with a wired / wireless remote control at a distance. These industrial / heavy-weight remote controllers require a customized remote controller depending on the driving method and requirements of each equipment. Compared with the remote controller for indoor use, the industrial remote controller can cause serious accidents due to the nature of the outdoor environment and malfunction, so its reliability evaluation is very difficult. The industrial remote control includes a plurality of direction buttons for indicating the operation direction of the operation target facility / equipment, a wired or wireless transmission means, a rotary power supply switch for turning on / off the power supply of the remote control, And an emergency stop button switch for immediately stopping the operation of the target facility in an emergency, is mounted on the upper part of the case, and an electronic circuit board for controlling the function of the remote control is mounted in the case.
In particular, emergency stop button switches and power supply switches are very important for preventing accidents in industrial remote controls that operate large heavy equipment or facilities. In order to prevent a safety accident, the power supply switch of the remote controller must be turned off to shut off the power supply of the remote controller. Furthermore, the emergency stop button switch, which is the last means of preventing accidents, requires more reliable watertightness due to the nature of outdoor work. In this industrial remote control, unlike the button switch of the general electronic device, the emergency stop button switch and the power supply switch have a characteristic that the pressed state or the rotated state of the button must be stably kept constant until the operation is released.

An inner region corresponding to the outer periphery of the holder is formed as a through hole and is fitted along the outer periphery of the holder and is tightly coupled to the upper surface of the case; And an upper portion of the through hole has a through hole having a diameter allowing the button cap to move up and down, and one end thereof protrudes outward to identify the rotation direction And a rotation member (55) which is fitted in the upper portion along the outer periphery of the plate and rotates along the rotation guide groove. The rotary member (55) has a protruding member And a power supply switch (200)
A first magnetic member is coupled to a button lower member of the emergency stop button switch, a second magnetic member is coupled to a protruding member of the power supply switch,
A first magnetic field sensor for sensing that the first magnetic body is lowered is mounted on a corresponding region of the upper surface of the substrate and a second magnetic field sensor for detecting that the second magnetic body is rotated to a predetermined position is mounted on a corresponding Wherein the first magnetic field sensor and the second magnetic field sensor are disposed at a predetermined distance from each other,
Wherein the emergency stop button switch and the power supply switch are integrally formed in a holder of the case. 3. The method of claim 2,
The bottom surface of the holder of the case is completely sealed with the lower portion of the case and the upper and lower portions of the case are molded and injected so that the lower portion of the holder of the button lower member is vertically hermetically sealed to the outer peripheral edge of the holder,
The first and second magnetic field sensing sensors may include a reed switch for sensing the approach of the first and second magnetic bodies to turn on and off the contacts, And a hall sensor for generating an ON / OFF signal based on a result of comparing the voltage generated by the emergency stop button switch with a predetermined reference value. Is an industrial remote control consisting of an integral assembly.
