Other functional implementations can be custom developed.Several functions of coal train contour identification and automatic positioning loading system are as follows：

I. Automatic reading of vehicle information：

By installing the car number recognition instrument, when the carriage passes through the car number recognition instrument, the system reads the vehicle information inside the electronic label of the carriage automatically and combines the read vehicle information: model, car number, ticket weight and weighing information into the comprehensive information of the carriage and generates the report automatically in the control system.

II. Automatic weighing of empty wagons：

As there is an error between the standard tare weight and the actual tare weight of the carriage, some even differ by as much as half a ton, if calculated by the standard tare weight, the actual amount of coal loaded will be much more; in order to achieve accurate loading, the approved load of the vehicle matches the actual loading, the empty tare weight should be reweighed before loading, and the measurement is calculated by the weighed tare weight, and each car is stopped and statically weighed during the empty weighing process.

III. Automatic loading function：

This function is the core of precision loading control system, which can complete the precision loading control of single carriage under the guidance of preset loading strategy. It is a comprehensive closed-loop control system integrating rail scale weight signal acquisition, loading status judgment and coal feeder belt control, which is used to complete the real-time control of single carriage loading process. After receiving the loading command and working condition information from the management control module, the loading control module calls the corresponding loading program and controls the coal feeder belt and the iron ox motor according to the predetermined loading strategy to complete the loading of different types of carriages. This function is a combination of many functions as follows：

IV. Actual loading effect: balanced loading, no set weight, no partial load

1）Vehicle precision positioning function: the vehicle position sensor determines the precise parking position of each wagon on the rail scale.

2）Balanced loading function: We divide each wagon into several virtual points, and set up balanced apportionment of tonnage at each point according to the principle of "balanced loading, no weight collection and no biased loading" of the railroad department.

3）Precision metering function: When the loaded tonnage reaches the precision control point, the system enters the point loading precision operation mode.

4）Prevention of humane loading function: In the process of loading, due to the realization of automatic loading, reducing the human link, the loading of the car, in function through the software set a series of chain functions, from the source to eliminate humane in loading.
The maximum loading error in the automatic loading report is 60Kg, the minimum is 0Kg, and the average loading error is 23.2Kg, which is far less than the 200Kg error specified by the shipping and marketing office.

V. Network docking function：

After the automatic loading is completed, the data of the loading is automatically saved in the local database, while the upload data is automatically generated according to the data format of the shipping and marketing office and can be uploaded to the shipping and marketing metering network at any time.

Local database and remote Orcle database interfacing.

Uploading data to a remote Oracle database through a bulk connection.

Use the script to query the local database and the remote database for uploaded data.

VI. Analysis of effects：

1、The measurement is standardized and precise, and the average loading error is less than 0.05T/truck, far less than 0.2T/truck as stipulated by the group company's measurement management.

2、The rate of set weight, partial load, wrong load and overload is "0", the balanced load is much higher than the manual load measurement level, the accuracy rate of faulty car identification is 100%, and the error rate is "0".

3、Fast loading speed: The average loading time is 4 minutes and 10 seconds per truck, and the fastest is 2 minutes and 30 seconds per truck, based on the high accuracy and the existing equipment.

4、Human resources have been saved. Normally, two people are needed for centrally controlled loading and metering, but now only one person is needed to complete all loading and metering work due to the input of automated loading equipment.

5、It is the functional extension of the transportation and sales measurement management software, which realizes the automatic control management system of loading and measurement in one. This research and development project is the leading one in the national coal loading and measurement management.
