Control method for fuel entry and exit factory unattended system of thermal power plant

Abstract

The invention relates to a control method for a fuel entry and exit factory unattended system of a thermal power plant; the unattended system comprises a system control module, an automatic scanning device, a sampling and sample preparing and testing device and a weighing device, and the control method carries out automatic scanning, sampling, weighing and vehicle locking alarm on vehicles which enter and exit the thermal power plant, further applies the positioning technology, the automatic sampling and sample preparing and testing technology, the voice prompt technology, the traffic light prompt technology and the like, improves the working efficiency, improves the economy and the safety of the operation of the thermal power plant, further realizes automation of entry factory, sampling,weighing, coal unloading and empty vehicle weighing, effectively saves staff cost, greatly improves production efficiency, effectively monitors time periods among various processes of the vehicles which enter the factory, effectively solves the chaotic order of entering the factory, and greatly improves the efficiency of the vehicles which enter and exit the factory of the thermal power plant.

Description

field of invention [0001] The invention relates to a control method for an unattended system of fuel entering and leaving a thermal power plant, in particular to a control method for checking, sampling, testing, weighing and locking vehicles entering and leaving a thermal power plant. An unattended control method for accurate efficiency monitoring of vehicles. Background technique [0002] With the further development of our country's economy, especially after the implementation of the power system reform with the main content of "separation of factories and grids, bidding for grid connection", the original operating mode in the form of power generation workshops under the planned economy has completely changed, and power plants have gradually become independent operations. market economy entities. While thermal power plants gain greater autonomy in production and operation, they also increase the pressure on operation and management, and cost control is one of the main pre...

Problems solved by technology

[0004] At present, there are mainly the following problems in the control method of the existing vehicles entering and exiting the thermal power plant system: the large amount of coal incoming by vehicles is difficult to unload: the average daily loading and unloading is 20,000 tons for 12 hours per working day, and the average net weight of each vehicle is 30 tons. 55.6 vehicles need to be unloaded per hour, that is to say, one car must be unloaded per minute, and the current configuration of each car from sampling to overweight cannot meet this requirement; the labor intensity of personnel is too large and the degree of automation is low: In order to meet the average daily loading and unloading capacity, only rely on 24-hour all-weather operation to make up for the lack of time, and the 24-hour operation has a large increase in personnel, high intensity, and low night safety operation coefficient; on-site management is difficult: due to the number of coal yards There are many, the traffic of coal-pulling vehicles is large, the time control of vehicles entering and leaving the factory is chaotic, and the on-site data transmission is not timely and accurate, which affects the statistical settlement work
