Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention will be further described as follows:
[0014] As shown in the accompanying drawings, the present invention designs a depth indicator based on serial bus RS-485, and the core control part of the depth indicator selects AT89C52 single-chip microcomputer. The single-chip microcomputer is connected with the host computer through the RS-485 bus, continuously receives relevant data, drives the digital and LED display parts through the bus, and displays the position information of the detected object in real time. The depth indicator communicates with the upper computer through the RS485 interface, and the data received by the interface is displayed through the LED digital display tube and the LED light bar. The depth indicator is mainly composed of three parts: control circuit, RS-485 interface and display circuit. The control circuit is composed of AT89C52 and power supply; the RS-485 interface is compos...

The invention relates to a special depth indicator for a mining elevator. The front side of the shell of the indicator is provided with an LED digital tube, an LED display light cross, a depth toplimit adjusting knob, a communication interface and a power supply interface, and a control circuit and a display circuit are arranged in the shell of the indicator, wherein the control circuit is respectively and electrically connected with the display circuit, the depth toplimit adjusting knob, the communication interface and the power supply interface, and the display circuit is electrically connected with the LED digital tube and the LED display light cross. The special depth indicator can visually display the operating speed and the position light cross of a winch in real time, has the advantages of high accuracy, compact structure, small overall dimensions, high pressure resistance and visual display of winch position, and has the functions of power-on self test and depth adjustment. Besides, the special depth indicator uses two display modes of digital display by the LED digital tube and graph display by the LED display light cross, wherein the display by the LED digital tube can accurately display the current position of the winch, and the graph display by the LED display light cross can visually display the current position of the winch.
Description
[technical field] [0001] The invention relates to the technical field of control systems, in particular to a special depth indicator for mine hoists. [Background technique] [0002] Dispatching winch is a common traction tool in mining areas, which plays a very important role in cargo lifting, but the lifting depth indication of dispatching winch has always been a thorny problem. The traditional depth indicating structure is purely mechanical, consisting of large internal gears, lead screws and other transmission components. Through the rough estimation of the amount of thread rotation and the amount of lowering the rope, there are high requirements for the operator's operating experience. The manufacturing cost of this mechanical depth indicating structure is very high, and the desired effect cannot be achieved. Common depth indicators are: gantry type, archway type, disc type, digital type. [0003] The characteristics of the gantry-type and archway-type depth indicators...
