Description
Technical field
The utility model digital remote belt conveyer scale belongs to the belted electronic balance technical field.
Background technology
Belted electronic balance is the measuring apparatus of band conveyor loose unpacked material.Present domestic belted electronic balance is that parts such as scale frame, LOAD CELLS, tachogenerator, weighing instrument and signal cable constitute by Weighing force transmission mechanism normally.Scale frame, LOAD CELLS and tachogenerator are installed in the scene, weighing instrument is installed in the pulpit away from the scene, the transmission of 0mv-20mv voltage signal is adopted in sensor to the transmission of the weight signal between the instrument, it is analog signal transmission, after weighing instrument carries out the A/D conversion with voltage signal, carry out the integrating and the display result of cumulative amount.The shortcoming of sort signal transmission mode is: transmission range is short, and the decay of signal is very big in the transmission course, weight signal amplifies through signal, effective resolution is low after the analog to digital conversion, signal noise is big, and temperature is floated greatly, and is bigger to the metering performance influence of belt conveyer scale, and weight signal line and the independent separately cabling of rate signal line need, the large usage quantity of signal wire.In addition, as because of the communication signal line opens circuit, short circuit or interference cause that communication failure interrupts transmission, will influence metering and cause output to lose.
The utility model content
The utility model overcomes the deficiencies in the prior art, and technical matters to be solved has provided the digital remote belt conveyer scale that a kind of transmission range is long, measuring accuracy is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the digital remote belt conveyer scale, comprise situ part and pulpit, situ part comprises scale frame, LOAD CELLS and tachogenerator, the pulpit comprises Displaying Meter, LOAD CELLS and tachogenerator are installed on the scale frame, situ part also comprises integrator, described integrator comprises single-chip microcomputer and communication module, LOAD CELLS all is connected with the input interface of integrator with tachogenerator, and the output interface of integrator is connected with the input interface of Displaying Meter by the communication signal line.
The communication module of described integrator or be the RS485 communication module, or be the CAN communication module, or be the MODEN communication module, or be the optical-fibre communications module, or be the ethernet communication module.
The beneficial effect that the utility model is compared with prior art had is:
1, adopt digital signal to transmit long transmission distance.
2, totalized function is preposition, be about to integrator and be installed in the scene, LOAD CELLS to the distance of integrator has only 2 meters-3 meters, weight signal is almost not decay when transmission, and adopt the digital data transmission mode when signal passed to Displaying Meter, long Distance Transmission does not have any decay, has improved measuring accuracy greatly.
3, the communication signal line opens circuit, short circuit or interference cause when communication failure interrupts transmission, does not influence metering, also just can not cause output to lose.
Description of drawings
