Embodiment Construction

[0030] The present invention is described in further detail below in conjunction with embodiment.

[0031] Such as figure 1 As shown, the mining truck engine cylinder temperature early warning system includes setting up a data acquisition terminal 2 on the truck 1. The data acquisition terminal 2 is used for real-time data acquisition and transmission. The output end of the data acquisition terminal 2 is connected to the background server 3 through the network. The output end of the server 2 is connected to the user terminal 4;

[0032] Such as figure 2 As shown, the data collection terminal 2 includes: a GPS sensor 21 for collecting the truck speed; a Hall sensor 22 for collecting the truck engine speed; a temperature sensor 23 for collecting the cylinder temperature, coolant temperature, and exhaust gas temperature , intake pipe temperature and oil temperature, etc.; pressure sensor 24, used to collect engine crankcase pressure, coolant pressure, increase pressure and tur...

Abstract

The invention discloses an early warning system and method for the temperature of an engine cylinder of a mining truck. The method comprises the following steps that S1, a data acquisition terminal is erected on the truck, and the data acquisition terminal is used for real-time data acquisition and transmission; S2, the data acquisition terminal is connected with a background server through a network to upload real-time truck operation data; S3, the background server screens related independent variables based on Spearman correlation coefficients through big data analysis service, and constructs a cylinder temperature prediction model by adopting a gradient lifting regression tree algorithm; and S4, the background server estimates a cylinder temperature predicted value in real time through a monitoring module, compares the actual cylinder temperature with the predicted value through an alarm module, and sends early warning information to inform a user of necessary inspection of the truck when the actual temperature and the predicted value have a large deviation and are continuous.

Description

technical field [0001] The invention relates to the technical field of engine temperature early warning, in particular to an early warning system and method for engine cylinder temperature of mining trucks. Background technique [0002] Mining trucks are an important production tool for open-pit coal mine operations. The dispatch rate and intact rate of trucks have an important impact on the production efficiency and economic benefits of coal mining enterprises. In order to improve the efficiency of trucks as much as possible, in addition to routine maintenance and maintenance work, it is very important to monitor the real-time working conditions of trucks. In order to meet the real-time monitoring requirements of trucks, it is generally necessary to install various sensors on the truck, such as vehicle speed, oil temperature, cylinder temperature, etc., and upload real-time data through the mobile network. [0003] The existing truck monitoring system mainly uses fixed thr...
