Description
Technical field
The present invention relates to field of measuring techniques, particularly relate to the device and method that large-scale coal chemical enterprise coal car logistics route is followed the tracks of.
Background technology
Current domestic most coke-oven plant adopts traditional top to coaling coke making process, coke oven top has coal tower scale to carry out Weighing to coal car, continuous data is the Main Basis of coking cost analysis, and therefore the accuracy of coal tower scale data plays a part very important to coking coking cost analysis.For coal tower scale automatic data collection problem, most enterprise adopts PLC to realize the unattended metering of coal tower scale, namely by signal cable, the current signal of coal tower scale is sent to PLC, by the gross weight of coal car after routine processes, tare weight, net weight, the data feedbacks such as cumulative amount are to supervisory control comuter, although this method solves coal tower scale unattended metering problem, but because coal car lacks monitoring in operational process, coal car is at dress, in process of unloading coal, existence is not gone up scale after coalingging and is measured the situation of directly unloading coal, obviously the coal tower scale data drawn by this method are inaccurate.
When using other funnel coal, coal car is not partially or completely on coal tower scale, and in this case because coal car is not on scale, current curve can not reflect the behavior of coalingging of coal car, so just there is cheating.For the weighing process of coal car, empty wagons enter coal tower scale stable after, metering tare weight (corresponding last firehole), then under coal car moves to coal bunker, open feed opening automatic stoking, fill rear coal car and move to again on scale, metering gross weight (corresponding this answers the firehole of coal).Gross weight is corresponding with tare weight, calculates the net weight of the coal adding a firehole, if obviously coal car is weighed not in accordance with above-mentioned metering process, so just there is metering cheating, affects the authenticity of data, accuracy.
Summary of the invention
The object of this invention is to provide a kind of coking coal car logistics route tracking device, to solve the problem of existing coal car metering cheating.
Another object of the present invention is to provide a kind of coking coal car logistics route tracking.
A kind of coking coal car logistics route tracking device, comprise coal car, coal tower scale, PLC, supervisory control comuter, switch board, PLC is arranged in switch board, it also comprises two groups of proximity switches, namely the first proximity switch and the second proximity switch are one group, 3rd proximity switch and the 4th proximity switch are one group, two groups of proximity switches are arranged in the both sides of described coal tower scale, described coal tower scale is fixedly mounted on rail, first proximity switch, second proximity switch, 3rd proximity switch and the 4th proximity switch are fixed on rail, first proximity switch, second proximity switch, the on-off model of the 3rd proximity switch and the 4th proximity switch is respectively by the first signal cable, secondary signal cable, 3rd signal cable and the 4th signal cable deliver to the switching value module in PLC, coal tower scale current signal delivers to the analog module in PLC by the 5th signal cable, through processor module, again data are delivered to supervisory control comuter.
When the method that above-mentioned coking coal car logistics route tracking device carries out following the tracks of comprises the steps: that coal car is delivered coal to coke oven, coal car leaves to coal bunker, empty wagons coal, then coal car leaves and measure gross weight to coal tower scale, gross weight signal delivers to the analog module in PLC, coal car is through two proximity switches, the switching value module that the signal of two proximity switches is delivered in PLC successively carries out record, coal car arrives above coke oven and unloads coal, then coal tower scale is back to through two proximity switches, the switching value module that the signal of two the second proximity switches is delivered in PLC successively carries out record, metering curb weight and tare weight, tare weight signal delivers to the analog module in PLC, empty wagons tare weight is corresponding with loaded vehicle gross weight, calculate this car to feed in raw material net weight.
The present invention is directed to coal tower scale and can only carry out data acquisition to the coal car of normal loading, unloading coal, and leakage adopt requiring that not in accordance with the measure of production the coal car carrying out loading, unloading coal will produce, thus cause data distortion, bring the problem of impact to coking cost analysis and develop, usually above coal tower scale, direction along ng a path has some coal bunker funnels, middle hopper is positioned at directly over scale, when using this coal bunker funnel coal, add coal car to be placed in completely on scale, in this case coal tower scale current curve there is not cheating possibility, because can reflect the behavior of coalingging of coal car completely.
Compared with prior art have the following advantages:
1, the present invention can to the complete monitoring of coal car loading, unloading coal operation behaviour, stop the metering cheating of coal car driver, achieve and adopt counting loss certificate without leaking, ensure that the authenticity of coal car continuous data, improve the accuracy of coal tower scale continuous data, thus reach normative operation behavior, for cost accounting provides reliable continuous data, make enterprise's material production, consume achieve become more meticulous, information-based, scientific.
2, the present invention plugs metering leak, for technique scale transformation and newly-builtly provide direction, greatly promoted the saving of enterprise's material energy, created considerable economic benefit, there is very high promotional value.
