Abstract

The invention discloses a coal mine vertical shaft skip bucket weighing and displaying device. The coal mine vertical shaft skip bucket weighing and displaying device comprises a sensor module, a signal acquisition and conditioning module, a master controller module and a touch screen. The sensor module is a pressure-magnetic sensor, the signal acquisition and conditioning module is composed of anexplosion-proof housing, an ultra-precision amplification circuit, a transmitter and a test calibration circuit, the ultra-precision amplification circuit is composed of a precise instrument operational amplifier and a chopper-stabilized operational amplifier, and the master controller module is composed of an explosion-proof housing, an analog quantity expansion module EM235 and a controller S7-200PLC. The invention relates to the technical field of coal mine vertical shaft skip bucket loading and weighing. The coal mine vertical shaft skip bucket weighing and displaying device can accurately detect the weight of coal in a skip bucket, and is characterized by being low in cost, high in accuracy and reliability and strong in anti-interference performance, and can display and monitor the weight of coal in the skip bucket on the touch screen in real time, and draw a vertical shaft coal output curve graph, and satisfies the safe and accurate demand during the coal mine skip bucket lifting process.

Description

technical field [0001] The invention relates to the technical field of coal shaft skip loading and weighing, in particular to a coal mine shaft skip weighing and display device. Background technique [0002] Coal mine vertical shaft skip loading is a key link in the lifting system. The control of the one-time loading of the skip is related to the efficiency and safety of mine skip lifting. According to Article 382 of the "Coal Mine Safety Regulations": "The skip lifting must use fixed weight loading" , so it is particularly important to control the weight of coal in the skip. Existing invention patent such as publication number is CN106124016A, adopts single-chip microcomputer Atmegal28 as data processor and builds weight measuring circuit. In practical application, this device has inaccurate signal acquisition and conditioning effects, secondly, the main controller Atmegal28 single-chip microcomputer is unreliable in underground work, and finally there is no good human-com...
