The automatic Batching system can meet the requirements of users in many aspects, with perfect operation and alarm records, all data can be queried and printed online, and the auxiliary functions such as channel switching and automatic shift switching are expanded. Perfect database and report function. This Weighing system has a complete function of data recording and statistical report, which meets the needs of enterprise production management. All kinds of reports include: shift operation report: including the start and end time of each shift, the control target value set according to the formula, the operation data of each scale, the batching output and the average hourly output of the reaction kettle, etc. Daily report and monthly report: the content is the same as above, and statistics can be made by shifts. Cumulative statistical report: specify the single scale and cumulative output within the start and end date and time, and make statistics and proportion according to the classification of materials. Alarm record report: including alarm classification statistics, alarm times and alarm waiting time, that is, the accumulated time from the alarm issued by the microcomputer to the keyboard response of the operator.

Formula modification, query and report printing can all be done online. The operator can modify or re-enter the formula in use online, and the system will run according to the new formula after confirmation. All the above-mentioned reports can be queried and printed online, without exiting the control operation process. The online query also includes the dynamic compensation coefficient of each scale, which is convenient for the operator to master the operation of the system.

Diversified mathematical calculation methods. The program of this weighing control system has been improved, and three different mathematical calculation methods between AD sampling voltage and weight are provided for users to choose. "Linear regression" can better overcome the random error caused by external factors, such as stirring, in the calibration process of weighing module, so that the setting results have better adaptability. "Curve fitting" is particularly effective in correcting the nonlinearity of the sensor, and can be compared and selected according to different situations.

For the control channel with continuous PID adjustment mode, the system also allows it to be set to calculate the conveyor load with "absorption value method", and this channel can be measured with a nuclear scale. The multi-functional characteristics of this batching system are fully reflected here to meet the special needs of users. After changing the calculation method, it can be operated directly without recalibration.

Flexible channel switching function of automatic feeding system When a certain A/D, D/A analog channel and D/O switch output channel are in fault, the user can call the submenu operation function of "Scale Group Definition" at any time, simply change the fault channel to the standby channel number, and switch its hardware connection line to the corresponding terminal, and the system can immediately resume continuous operation. This function is particularly convenient and quick to handle faults when there are problems in the electric vibration trigger board or individual channels of microcomputer I/O board.
