Abstract

The invention relates to a wireless dynamic transmission device which comprises a sensor, a wireless dynamic transmitter and a wireless dynamic receiver. The wireless dynamic transmitter comprises a first power source, an amplifying comparison circuit, a time-delay output circuit and a wireless transmitting circuit; and the wireless dynamic receiver comprises a second power source, a wireless receiving circuit, a time-delay circuit and a relay circuit. The output signal of the sensor is wirelessly transmitted to the wireless dynamic receiver through the wireless dynamic transmitter, and the relay circuit sends control signals to a subsequent controller. The wireless dynamic transmission device has the advantages as follows: because wireless reception and transmission are two independent units, signal transmission between the both is realized by adopting a radio wave, thereby eliminating signal connecting cables, avoiding the damage and the routine maintenance of the signal cables, and effectively ensuring the smooth transmission of the signals. Through the field simulation test, the wireless dynamic transmission device has the advantages that the signal transmission is reliable, the control action is sensitive, the operation is convenient, the performance is sufficient for satisfying the practical application, and the wireless dynamic transmission device provides reliable guarantee for the safe production of coal mines.

Description

technical field [0001] The invention relates to a control device, in particular to a wireless dynamic transmitter. Background technique [0002] At present, in the equipment used in underground coal mines, the control part and the sensor part mostly adopt the method of connecting cables to transmit signals. If the control part and the sensor part of the equipment are far apart, many cables need to be laid. Due to the special environment of the underground coal mine, when the signal cable is damaged due to external force pulling or bumping, the signal transmission will be interrupted, which will bring hidden dangers to the safety of the coal mine. At the same time, the maintenance of the signal cable will also bring many problems to daily work burden. In order to solve the above problems, it is urgent to innovate the transmission technology of underground equipment in coal mines. Contents of the invention [0003] The purpose of the present invention is to provide a wirel...
