Description
Technical Field
The invention relates to the technical field of counting and turning joint control, in particular to an unattended counting and turning joint control system for train coal and a control method thereof.
Background
Most of the fire coal required by a thermal power plant is transported into a plant by a railway train wagon, a state railway locomotive pushes the train wagon carrying the coal to a static rail weighbridge area of a train unloading line of the power plant, traction power is provided for the train wagon by a shunting machine of a turn-back type tipper system, the train wagon is dragged section by section to carry out metering operation through the static rail weighbridge, and then the train wagon is dragged into the tipper to carry out unloading operation. The tippler system completes the metering and unloading work of each coal-carrying wagon in a turn-back type operation mode. The unloading operation of the coal-carrying vehicle is completed by the cooperative work of the static railroad track scale and the tipper system, and the unloading operation flow is as follows: a domestic railway locomotive pushes a whole train of coal-loaded wagons to a static rail weighbridge area of a power plant unloading line, and a tipper operator adjusts a first section of wagons to a metering parking space by controlling the traction or reverse pushing of a shunting machine, as shown in figure 1; after confirming that four wheels of the railway wagon are completely static on a weighing platform of the railway wagon and the weight of the instrument is stable, the railway wagon operator clicks a weighing button to complete the measurement of the first section of railway wagon. After the first section of wagon is weighed, the tipper operator pulls the first section of wagon to the wheel clamping device area by controlling the shunting machine until the second section of wagon reaches the metering parking space, as shown in fig. 2; and after four wheels of the train wagon are completely static on a weighing platform of the rail weighbridge and the weight of the instrument is stable, clicking a weighing button to complete the metering of the second section of train wagon. After the second section of train wagon is weighed, the tipper operator controls the shunting machine to pull the first section of train wagon to the unloader to unload, during which, the unhooking worker unhooks and separates the first section of train wagon from the whole train wagon in the wheel clamp area, the first section of train wagon is pulled to the unloader by the shunting machine to unload, the unhooked whole train wagon naturally decelerates to advance under the action of inertia due to loss of traction power until the second section of train wagon stops in the wheel clamp area, and at this time, a third section of train wagon to be weighed is on the weighing platform of the rail weighbridge, as shown in fig. 3; after the rail weighbridge operator confirms that the four wheels of the third section of train wagon are completely stopped on the weighing platform and the weight of the instrument is stable through manual work, the weighing key is manually clicked, and the weighing of the third section of train wagon is completed. And repeating the steps until the last train wagon finishes the coal unloading operation.
Since the railway train wagons are formed by mixing three series of train types of C62, C64 and C70, the length of the railway wagons of the C62 series and the C64 series is 13438mm, the length of the railway wagons of the C70 series is 13976mm, and the length of the railway wagons of the C62 series and the C64 series is 538mm different from that of the railway wagons of the C70 series. Under the condition of dumping of a mixed vehicle type, due to certain uncertainty of the manual unhooking position and the inertial travel distance of the rest whole train of wagons after unhooking, it is difficult to ensure that only four wheels of N +2 wagons are completely static on a weighing platform of a rail weighbridge under the inertial action after unhooking, and the metering condition that only four wheels of the same wagon are completely on the weighing platform in the railway coal transportation unloading process is not met.
When the metering condition is not satisfied, the following technical problems are brought about: (1) In the prior art, a metering operator and a tippler operator are required to frequently communicate and transfer, so that metering and unloading are not smooth, and unloading efficiency is influenced; (2) When the condition that the metering condition is not met exists, a certain probability that the condition is not found by a metering operator exists, and the condition is mistakenly taken as a metering condition to weigh, so that the metering data is inaccurate. Therefore, it is urgently needed to provide a train coal unattended operation, counting and turning combined control system and a control method thereof, so as to solve the technical problems of inaccurate metering data and low unloading efficiency caused by the fact that the metering conditions are not met in the prior art.

the stability monitoring unit 1000 is configured to determine whether a weighing result is stable, and when the weighing result is stable, the weighing result is a target weighing result.
The embodiment of the invention can ensure that the metering meets the metering condition by arranging the stability monitoring unit 1000, and further improve the metering accuracy.
In a specific embodiment of the present invention, the stable weighing result specifically comprises: the stability monitoring unit 1000 collects data of the weighing instrument in real time, performs difference calculation on the adjacent 50 frames of instrument data, and when the range of 50 groups of adjacent frames of data is smaller than a set range standard value, the weighing result is stable, otherwise, the weighing result is unstable.
It should be understood that: the standard range value can be set or adjusted according to empirical values, and is not particularly limited herein.
In order to avoid disconnection between the main control unit 100 and the unloading unit 600 caused by a crash, a power failure, and the like, when the main control unit 100 fails, the unloading unit 600 still performs unloading operation, which causes an error in the unloading operation, in some embodiments of the present invention, as shown in fig. 4, the train coal unattended operation roll-over joint control system 10 further includes a heartbeat monitoring unit 1100;
the heartbeat monitoring unit 1100 is configured to determine whether the main control unit 100 fails, and control the unloading unit 600 to stop unloading when the main control unit 100 fails.
It should be understood that: when the main control unit 100 is restored to normal, and when there is no railroad car that has not been metered into the unloader, the unloading operation of the unloading unit 600 is resumed.
The embodiment of the invention can further improve the reliability and the accuracy of the unloading operation of the unloading unit 600 by arranging the heartbeat monitoring unit 1100.
