Embodiment Construction

[0011] Such as figure 1 As shown, the present invention discloses a balancer, which includes a human-machine interface device 1 and a weighing instrument controller 2, and the human-machine interface device 1 and the weighing instrument controller 2 are connected through a field bus. The field bus is an arcnet bus, wherein the arcnet bus is a bus used by the ARCNET local area network. The arcnet bus has high real-time performance and fast communication speed, the highest speed is 1.5Mbps per second. The man-machine interface needs to be changed more or less according to different products. In the prior art, the visualization function of the man-machine interface is completed by means of a single-chip microcomputer. If the man-machine interface is slightly modified, the single-chip microcomputer program must be modified, and then the single-chip microcomputer program can be updated to achieve the purpose of modification. It is very inflexible. Scale manufacturers need to rely ...

Abstract

The invention provides a balancer, comprising a human-machine interface device and a balancer controller, which are connected with each other by a field bus. The balancer has the advantages that the human-machine interface device is connected with the balancer controller by the field bus, and the transmission speed of the field bus is further higher than the speed of serial port communication, so that the communication speed between the human-machine interface device and the balancer controller is improved.

Description

technical field [0001] The invention relates to a precision instrument, in particular to a balancer. Background technique [0002] The use of man-machine interface in the weighing instrument industry has a long history. In the electronic scales in people's daily life, everyone is already familiar with the display methods of some electronic digital tubes, which display the unit price, weight and total price of the current weighing item. As technology develops, there are many other products in the weighing instrument industry that require an HMI. In these products, the requirements for the man-machine interface are very high. Now the data interaction between the man-machine interface and the weighing instrument controller uses serial communication, which has defects such as slow communication speed. The slow communication speed between the human-machine interface and the weighing instrument controller directly leads to the inability to increase the production capacity, which...
