The invention relates to the technical field of weighing instrument zero clearing, and discloses a method for remotely controlling zero clearing of a weighing instrument, and the method comprises the steps: switching on a network cable through the closing of a zero clearing button on an industrial personal computer, enabling a first switch to obtain a zero clearing signal, and transmitting the signal to a first optical fiber transceiver through the network cable; sending all information of the industrial personal computer to a second optical fiber transceiver through an optical fiber, the second optical fiber transceiver converting received optical signals into electric signals, and sending the electric signals to a second switch through a network cable; leading a zero clearing contact of the weighing instrument out from an internal circuit board of the weighing instrument through a cable, the other end of the cable being connected with an output point of a control panel of the weighing system, additionally arranging a zero clearing button of the weighing instrument on an unmanned weight checking management system picture of the weighbridge installed on the industrial personal computer, and the output point of the control panel of the weighing system being closed by clicking the zero clearing button of the weighing instrument. Therefore, the zero clearing contact of the weighing instrument is closed, remote zero clearing of the weighing instrument is completed, the workload of maintenance personnel is reduced, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of zeroing of weighing instruments, in particular to a method for remotely controlling the zeroing of weighing instruments. Background technique [0002] Currently, there are roughly two methods for clearing the weighing instrument. The first method is to use the reset button on the operation panel of the weighing instrument to perform on-site zero reset. The second method is to use the industrial PLC to control the contact of the relay to make the weighing The zero contact of the heavy instrument is closed to realize remote zeroing. [0003] At present, in the field of unmanned weighing scales, there is no effective method and device for remote zeroing. In order to improve work efficiency and reduce maintenance intensity, it is necessary to combine the unmanned weighing scale management system to realize the remote zeroing function of weighing instruments. to solve the above problems.
