The invention discloses a vehicle-mounted large-volume data recording and vibration testing system for coal mining equipment, which consists of a host and an intrinsic safety vibration acceleration sensor, wherein the host consists of an embedded computer main board, a data acquisition card and a large-volume solid state drive. The embedded computer main board in the host receives and stores in real time external signals into the large-volume solid state drive through a board-mounted input / output (I / O) interface, and the external signals are from two sources: external signals which are collected by the control system of electromechanical equipment, transmitted to the host through a communication interface and stored in the large-volume solid state drive in real time, and external signals which are collected by the intrinsic safety vibration acceleration sensor, modulated by a signal modulation module, collected by a data acquisition card in the host, transmitted to the embedded computer main board by the data acquisition card through the communication interface and stored in the large-volume solid state drive in real time. The system is low in cost, high in precision, good in real-time and convenient in operation.
Description
technical field [0001] The invention relates to an instrument for collecting and recording state parameters of electromechanical equipment, in particular to an airborne large-capacity data recorder system that can be used for coal mine underground mining equipment. Background technique [0002] Coal mine underground large-scale mining equipment refers to various coal mining machines used in coal mine fully mechanized mining face and various roadheaders used in fully mechanized mining face. It is the most critical large-scale equipment in coal comprehensive mechanized production. [0003] Working underground, the working environment is harsh, the amount of dust is large, the visibility is low, the working space is narrow, and it is easy to deviate from the working direction and cause loss of mechanical equipment, so the requirements for equipment performance are high. Coal production is an industry with frequent fatal accidents, and the number of fatal accidents is far higher...
