The liquid filling machine receives the filling record generated by filling in real time, and sends the filling record to the base station. After the base station obtains the token of the server, it polls the filling scale under its jurisdiction in a time slice. If the wireless communication module of the filling scale has data to send, it must wait for the query local command of the base station to send it, otherwise it will not make any response. The base station is responsible for relaying the collected information.
020-34563445The weighing and Filling machine consists of a business layer composed of a filling Electronic scale, a data transmission layer composed of a wireless base station, and a data management layer composed of a background server. The filling machine communication module receives the filling record generated by the electronic scale in real time and sends the filling record to the base station. After the base station obtains the token of the server, it polls the filling scale under its jurisdiction in a time slice. If the wireless communication module of the filling scale has data to send, it must wait for the query local command of the base station to send it, otherwise it will not make any response. The base station is responsible for relaying the collected information.
The hardware system of measuring filling machine consists of base station and filling electronic scale. Filling electronic scale is responsible for the reading of the bar code of the filling barrel, the processing of the filling process and the display of information, and needs to transmit the filling record to the base station. The base station is responsible for the reception and forwarding of data, that is, the data received from the communication module is placed on the CAN bus, and the data received by the CAN module is sent out through the communication module. The filling machine controls the motor feeding, the weight of the material in the hopper is collected by the weighing module through A/D conversion, the weighing instrument constantly collects data and calculates the current feed speed of the hopper according to the collection time difference, and then compares the preset value with the weight of the material in the current filling scale and calculates the time to continue feeding. When the weight of the material in the filling is close to 70%~80% of the set value (specifically set by the software part of the weighing instrument), the filling port partially shrinks (medium input); when it is close to 80%~95% (specifically set by the software part of the weighing instrument), the feeding port shrinks to the smallest feeding port (small input). Finally, when the weight of the material in the filling scale and the weight of the air drop reaches the set value, the feeding port of the hopper is closed and the weighing is finished.
