Vehicle entry and exit factory unattended system and method of thermal power plant

Abstract

The invention relates to a vehicle entry and exit factory unattended system and a method 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 system control module comprises a server, a client computer and a network office device which are mutually connected through a computer local area network. The adoption of the unattended system can realize the automation of entry factory, sampling, weighing and empty vehicle weighing, effectively save staff cost, greatly improve production efficiency, effectively monitor time periods among various processes of vehicles which enter a factory, effectively solve the chaotic order of entering the factory and greatly improve 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 an unattended system and method for vehicles entering and leaving a thermal power plant, in particular to a method for improving the efficiency of vehicles entering and leaving a thermal power plant by monitoring, sampling, testing, weighing and locking vehicles entering and leaving a thermal power plant. High efficiency and precise monitoring unattended system. 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 an...

Problems solved by technology

[0004] The existing vehicles entering and leaving the thermal power plant system currently have the following main problems: The large amount of coal coming in from 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. The average hourly demand 55.6 vehicles are unloaded, that is, one car is to be unloaded every 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 daily The average loading and unloading capacity can only be compensated by the 24-hour all-weather operation method to make up for the lack of time, and the 24-hour operation has a large increase in personnel, high intensity, and a low night safety operation factor; on-site management is difficult: due to the large number of coal yards, 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
