/Overview of mine explosion-proof and intrinsically safe sound and light combined signal device: :: :
There are roughly two types of signaling devices currently used in belt conveyor lanes and elevator conveyor lanes. One is the traditional explosion-proof Electromagnetic type
Another type of electric bell is the combined sound and light signal electric bell, some of which have simplex intercom functions. The latter has made great progress in technology and function, but to realize functions such as multi-level signal differentiation and secondary transmission, automatic conversion of safety lights and signal blocking, it is still necessary to add a large number of cables and explosion-proof three-level Tongsitong, etc. require large investment and high failure rate. In response to the current situation, we
have developed and produced a mine explosion-proof and intrinsically safe sound and light combined annunciator. This product is flameproof in structure
and intrinsically safe in design. It uses a single-chip microcontroller and modem technology and only requires a five-core signal cable (no emergency stop function required
Only a four-core cable is required). ), which can realize the functions of simplex intercom, automatic differentiation of multi-level secondary transmission, traffic light conversion and signal blocking etc. Leading technology, reasonable design, one machine with multiple uses. It can be used in belt conveyor lanes and rail transport lanes, and small winches to lift transport lanes (can achieve signal locking and automatic switching of safety lights). It is an ideal replacement product for current acousto-optic signaling devices.
