Description
Technical field
Coal storage technical field is the utility model is related to, relates more specifically to a kind of towed monitoring system of closing bar shaped coal yard
System.
Background technology
In the operation of coal fired power plant coal yard, the temperature of coal load quantity and regional is two sets that operations staff is concerned about the most
Data.Original disk coal mode is by manually measuring dump with ruler, then being computed drawing coal yard coal load quantity.Coal fired power plant at present
The coal load quantity of coal yard is generally obtained by laser coal inventory instrument systematic survey；The temperature of dump regional is generally by infrared thermometer
System obtains.
The operation principle of laser coal inventory instrument is：The upper dump surface of coal yard is scanned using high-precision laser,
Collection surface shape information at the same time, then handled through computer and synthesize three-dimensional dump shape, so as to obtain the volume of dump.Then
By parameters such as the density that is previously set, coal yard coal load quantity is calculated.The operation principle of infrared thermometer is：Pass through reception
The infrared heat that dump surface is sent, the surface temperature of accurate judgement dump, then handled through computer to represent that dump is warm in real time
The image of degree.By software processing, dump real time temperature monitoring can be superimposed upon in the 3-D view that laser coal checking is formed, from
And form the coal yard three-dimensional real-time model with temperature information.
In current coal yard system, laser coal inventory instrument is typically mounted at the coal yard that can be walked mechanically.Wherein, cantilevered bucket
Wheel stacker-reclaimer is (referred to as " bucket wheel machine ") the most frequently used coal yard machinery of walking.Using bucket wheel machine as main Work machine coal yard system
In system, laser coal inventory instrument is often installed on its cantilever.Walked by bucket wheel machine, it can be achieved that disk coal operation.
In coal fired power plant, in view of the original of the external pressure of environmental protection and two aspects of internal motivation of coal-fired fine-grained management
Cause, traditional outdoor coal yard have gradually been closed coal yard replacement.
The general uneasiness of conventional surface coal yard system is coaling a temperature measurer.But in coal yard system is closed, in order to prevent dump
Spontaneous combustion, coal fired power plant need monitoring dump temperature in real time.The infrared thermometer of coal yard is generally using fixed point installation at present.

Shortcoming：First is that there are the blind area of disk coal, it is impossible to accurately coal pile volume information is obtained, so that can not obtain accurate coal yard deposits coal
Measure data；Second is that bucket wheel machine cannot be carried out at the same time in the operation of disk coal and heap material extracting operation, solely in order to disk coal operation, it is walked
Power consumption is very big；3rd is inevitably to produce to vibrate in bucket wheel machine walking process, and the equipment such as disk coal instrument is inclined because this vibration can produce data
Difference, causes measurement result inaccurate.
The infrared thermometer closed in coal yard system is generally installed using fixed point, since its temperature-measuring range is limited,
Each coal yard needs to install multiple devices, and there are blind area, it is impossible to effectively monitors the situation of whole coal yard.
The visual camera head for closing coal yard system generally pinpoints installation, or, coverage. installed in coal dust mechanically
It is small.
Therefore, new efficient, energy saving, non-blind area the towed coal yard monitoring system of exploitation is badly in need of in this area.
