Abstract

The utility model provides an electronic scale comprising a plurality of sensors and a controller connected with the plurality of the sensors. The electronic scale is characterized in that the input ends and the output ends of the plurality of the sensors are respectively connected with corresponding signal connector assemblies; the input ends of all signal connector assemblies are connected in parallel and are connected with a stable-voltage power supply; and the output ends of all signal connector assemblies are connected in parallel and are connected with the controller. Under the condition that one sensor has a fault, all electric connection of the sensor which has the fault is rapidly switched off and normal work of the other sensors is not influenced; and the continuous meting of materials is maintained and the smooth production is guaranteed, so that the problem in the prior art that the controller cannot work as one sensor is damaged is basically solved..

Description

A kind of electronic scales

Technical field

The utility model relates to a kind of electronic scales, and particularly a kind of electronic scales with a plurality of sensors belongs to the WT-MSR technical field.

Background technology

In process of production; Often will come material is carried out weighing with bunker scale or belt conveyer scale, the bunker scale or the belt conveyer scale that adopt at present be the electronic scales that is made up of a plurality of LOAD CELLSs and display mostly; And a plurality of LOAD CELLSs all adopt parallel way to be electrically connected; And shared stabilized voltage supply power supply, in case when certain sensor wherein damaged, its output valve occurred unusual; Must cause total output valve of a plurality of sensors that are connected in parallel unusual, thereby bunker scale or belt conveyer scale can't be worked.And maintenance expends time in emat sensor more, just has to suspend the use of bunker scale or belt conveyer scale thus, and material can't be measured, even causes production line to stop production, and brings economic loss to enterprise.Therefore be necessary prior art is improved.

Summary of the invention

When damaging for the some sensors in a plurality of LOAD CELLSs that solve existing electronic scales existence, with the problem that influences all the sensors operate as normal, the utility model provides the electronic scales of a kind of ability continuous working.

The utility model provides a kind of like this electronic scales; Comprise a plurality of sensors and the controller that links to each other with a plurality of sensors, it is characterized in that a plurality of sensor input ends and output terminal link to each other with corresponding signal socket connector respectively, link to each other with stabilized voltage supply after the input parallel connection of each signal socket connector; Link to each other with controller after the output terminal parallel connection of each signal socket connector; When damaging with the wherein some sensor of box lunch, take off corresponding signal socket connector just fast all of open failure sensor be electrically connected, fault sensor is isolated from system; And the sensor of other operate as normal still is retained in the system, and controller still can work on.

Said controller is commercial product.

Said signal socket connector is commercial product.

The utlity model has advantage and effect: adopt such scheme; Can be under the situation that some sensors break down; All of quick open failure sensor are electrically connected, and can not influence the operate as normal of other sensor, keep the continuous measurement of material; Guarantee carrying out smoothly of production, fundamentally solve prior art and damage the problem that causes controller to work because of some sensors.

Fig. 2 is the circuit structure diagram of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be further described.

The electronic scales that the utility model provides comprises four sensors 2 and the controller that links to each other with four sensors 2, and these four sensors 2 are installed on the hopper 4, like Fig. 1 through web member 1 and bearing 3 symmetries respectively; The input end of four sensor a1, a2, a3, a4 and output terminal link to each other with corresponding commercial signal socket connector B1, B2, B3, B4 respectively, after the input end parallel connection of each signal socket connector with the anodal V of D.C. regulated power supply ₊, negative pole V _-Link to each other, pass through mV after the output terminal parallel connection of each signal socket connector ₊, mV _-Signal output links to each other with conventional controller, like Fig. 2, when damaging with the wherein some sensors of box lunch, directly takes off the signal socket connector of correspondence, can break off fast with all of controller being electrically connected, and does not influence the operate as normal of all the other sensors.

Claims

1. electronic scales; Comprise a plurality of sensors and the controller that links to each other with a plurality of sensors; It is characterized in that a plurality of sensor input ends and output terminal link to each other with corresponding signal socket connector respectively; Link to each other with stabilized voltage supply after the input parallel connection of each signal socket connector, link to each other with controller after the output terminal parallel connection of each signal socket connector.
