The variable frequency driving unit comprises a frequency converter and a variable frequency motor, the variable frequency motor is arranged on the feeding belt conveyor, and an output shaft of the variable frequency motor is in transmission connection with the belt pulley. The variable frequency motor is connected with a frequency converter, and the frequency converter is preferably connected with a communication module 2 of the system controller through a Profibus-DP protocol to realize communication with the CPU.

The operation of the limestone dosing device of the present application will now be described briefly with reference to figures 2 and 3. Wherein, fig. 3 is a control circuit diagram of the limestone quantitative feeding device of the present invention.
As shown in fig. 2 and 3, when the limestone quantitative feeding device automatically operates, the system controller receives a set feeding amount signal and a starting signal of the remote controller in real time through a Modbus TCP/IP protocol, and then the system controller starts the frequency converter through Profibus-DP communication to drive the feeding belt conveyor to operate and convey limestone materials. In the conveying process, the system controller calculates the actual feeding amount in real time through the speed sensor signal and the load sensor signal, and compares the actual feeding amount with the set feeding amount. If the actual feeding amount is calculated as follows: the actual feeding amount is the calculation coefficient multiplied by the running speed of the feeding belt conveyor multiplied by the load of the material. When the deviation between the actual feeding amount and the set feeding amount is within the allowable deviation range, the running frequency of the frequency converter is unchanged, and meanwhile, the system controller transmits signals of the actual feeding amount, the equipment running state and the like to the remote controller in real time through ModbusTCP/IP communication. When the deviation between the actual feeding amount and the set feeding amount is out of the allowable deviation range, PID control is carried out on the frequency converter, a PID control unit in the system controller calculates the working frequency of the frequency converter in real time according to the deviation between the set feeding amount value and the actual feeding amount, and then the working frequency of the frequency converter is adjusted through Profibus-DP communication. In the working process, if the actual feeding amount suddenly deviates from the set feeding amount, the system controller sends an alarm signal to drive the audible and visual alarm to flash, and meanwhile, the alarm signal is transmitted to the remote controller; when the alarm disappears, the limestone quantitative feeding device automatically resets. If equipment such as a frequency converter and the like has a fault signal, the system controller gives a stop signal to drive the audible and visual alarm to be on constantly, and the limestone quantitative feeding device cannot be automatically reset.
In order to improve the control precision, after the limestone quantitative feeding device automatically operates for a period of time, the calculation coefficient is calibrated. The calibration process may be: randomly extracting a batch of materials from limestone materials conveyed by a feeding belt conveyor, conveying the batch of materials to a high-precision wagon balance for weighing, then comparing the feeding amount calculated based on the weighing weight of the batch of materials with the actual feeding amount automatically calculated by a system, calibrating and correcting the calculation coefficient if the deviation of the comparison result is outside a preset range, and continuing feeding if the deviation is within the preset range.
When the limestone quantitative feeding device is manually operated on site, a site operator presses a site start-stop button, and the system controller receives a set value of a site speed regulating knob and transmits the corresponding working frequency to the frequency converter through Profibus-DP communication to drive the feeding belt conveyor to operate. And the control system controller calculates the actual feeding amount according to the received speed sensor signal and the load sensor signal and transmits the actual feeding amount to the remote controller through Modbus TCP/IP communication. When the feeding belt conveyor breaks down, an operator presses a field emergency stop button, the feeding belt conveyor stops running emergently, and the audible and visual alarm is on constantly.
It should be noted that, in the above embodiments, data transmission is performed by using the Modbus TCP/IP protocol and the Profibus-DP protocol, but the cost and transmission efficiency of the device are balanced by using the preferred method, and in practical applications, data transmission may also be performed by using other methods, and as technology develops, alternative methods with lower price and higher transmission efficiency will inevitably occur. The sensor unit in the embodiment adopts a speed sensor and a load sensor, and other sensors which are in line with the production scale in practical application can be adopted as long as the data collected by the sensors can be applied to the subsequent calculation of the actual feeding amount. Similarly, the variable frequency driving unit can also adopt other forms of equipment. Besides the above setting mode, the field control unit can omit a field emergency stop button or add other buttons such as a field alarm button. In a word, the utility model discloses a protection object is the macroscopical framework that variable frequency drive unit, sensor unit, field control unit, system controller, remote control constitute, and not these units or the concrete function or the operation of its submodule piece, also not the interactive mode or the method between these units, consequently, under the prerequisite that does not violate this kind of macroscopical constitution, the utility model discloses a limestone dosing device's concrete component part can adjust and change as required, and the feeder after adjustment and change does not deviate the basic principle of the utility model, consequently will fall into within the protection scope. For example, the system controller that loads various different control programs can be used in the present invention, the protection object of the present invention is not the program itself loaded and executed by the system controller, but the integrated device composed of the system controller, the sensor unit, the variable frequency driving unit, the remote control unit, and the field control unit.
