Embodiment 1）
[0040] See figure 1 , the mine equipment lubricating oil state online monitoring system of this embodiment is mainly composed of a sensor 1, an oil analyzer 2, a CAN bus 3, a communication host 4, a monitoring center server 5 and a client computer 6.
[0041] There are at least one sensor 1 and oil analyzer 2 respectively. When there are multiple lubricating oil points to be measured in mining equipment, the number of sensors 1 and oil analyzers 2 set is the same as the number of points to be measured. The sensor 1 is arranged at the point to be measured of the mining equipment and is fully in contact with the lubricating oil at the point to be measured.
[0042] Sensor 1 is electrically connected to oil analyzer 2 through the CAN bus; when multiple sensors 1 and 2 are installed, one sensor 1 is electrically connected to one oil analyzer 2; oil analyzer 2 passes The CAN bus 3 is electrically connected with the communication host 4 with bidirectional signals; the communicatio...

The invention provides an online lubrication oil state monitoring system of a mine device. The online lubrication oil state monitoring system comprises sensors, oil analyzers, CAN buses, a communication host, a monitoring center server and a user end computer, wherein each lubrication oil monitoring point of the mine device is provided with a sensor; the number of the oil analyzers is as same as the number of the sensors; the sensors are electrically connected with the oil analyzers through the CAN buses; the oil analyzers are in bi-directional signal electrical connection with the communication host through the CAN buses; the communication host is in bi-directional signal electrical connection with the monitoring center server; the user end computer is in bi-directional signal electrical connection with the monitoring center server. The monitoring method mainly comprises the following steps that the oil analyzers set and store initial parameter values and an alarm threshold, the sensors collect parameters, and the oil analyzers analyze and process to judge whether to alarm or not. According to the online lubrication oil state monitoring system of the mine device, and the monitoring method of the system, which are disclosed by the invention, the structure of the system is simple, the monitoring method is realized conveniently, the lubrication oil of the mine device can be monitored effectively online in real time, and the reliability of the detection result is high.
Description
technical field [0001] The invention relates to the technical field of real-time monitoring of the operating state of coal mine underground equipment, in particular to an online monitoring system and a monitoring method for the state of lubricating oil of large coal mine equipment. Background technique [0002] Lubricating oil plays a very important role in the normal operation of large-scale mining equipment. Pollution and deterioration of lubricating oil will lead to degradation of mechanical equipment performance, shortened life span, and even lead to accidents in severe cases. Therefore, it is necessary to monitor and analyze the state and deterioration degree of lubricating oil in mining equipment. Common pollution states of lubricating oil in mining equipment include coal powder and wear particles in lubricating oil exceeding the standard, oil and water emulsification, etc. At present, the devices for monitoring and analyzing lubricating oil in equipment mainly includ...
