Description
Technical field
Small weighbridge field of instrumentation technology is the utility model is related to, it is particularly a kind of to make with four simulation weighing sensors cooperations
The small weighbridge instrument of New-type mould revolution.
Background technology
Small weighbridge is a kind of less electronic scale in truck scale, convenient to use, metering is accurate, reaction speed spirit
Quick, conveniently moving, the small platform balance that need not be laid the foundations, as long as can freely it be weighed to goods in same ground level, four
Respectively there are a sensor, simple structure in each angle in angle.
Small weighbridge is divided into digital sensor weighbridge and analog sensor weighbridge, wherein digital sensor weighbridge in the market
By the small weighbridge instrument of numeral and digital sensor group into, debugging convenient function dimension is scheduled on big weighbridge and is generalizable, but due to
Digital sensor cost is high, cannot be popularized in small weighbridge.Analog sensor is largely popularized because cost is low in the application of small weighbridge,
But simulation sensor inconvenient debugging, performance is unstable, and instrument used in two kinds of weighbridges is specifically described as follows：
1st, small weighbridge instrument is simulated
It is made up of as shown in figure 1, simulating small weighbridge instrument simulation potentiometer terminal box and the small weighbridge display instrument of simulation, often
One simulation weighing sensor is connected with a potentiometer in terminal box respectively, and it is sensitive that each simulation weighing sensor has output
The problem of inconsistent is spent, if directly angular difference occurs in parallel sensor supply instrument use, at this moment needs to connect by potentiometer
Line box adjustment enables each simulation sensor output sensitivity is basically identical to be just connected in display instrument.
In order to eliminate angular difference, the sensor that technical staff will be constantly in each angle position puts weights and checks ISN and then adjust current potential
Device eliminate angular difference, operating technology personnel need constantly repeatedly formulation code see ISN adjust potentiometer, to technical staff's technical requirements compared with
It is high, it is necessary to by certain time training, and labor intensity is higher wastes time and energy in debugging, the sense in debugging and by people
Feel adjustment potentiometer, be not very accurate.Complete weighbridge angle modulation in transport or long-play is to be easy to using middle potentiometer resistance
Change, so cause angular difference occur again.
2nd, the small weighbridge instrument of pure digi-tal
As shown in Fig. 2 the small weighbridge instrument of pure digi-tal is by 4 digital sensors, four simulation weighing sensors, digital wiring
Box and the small weighbridge display instrument composition of numeral, digital sensor integrate AD, MCU and 485 chips, can gather analog signal
And data signal is switched to by AD conversion chip, then by the data that MCU is calculated by 485 chips send to terminal box and
Bus supply digital instrument uses, and such small weighbridge instrument of a numeral includes 4 AD conversion chips, 4 MCU and 4 485 cores
Piece, its chip is more, therefore the small weighbridge device cost of numeral is high, and power consumption is high, and processing cost is also high, is not generalizable also.
In view of this, the present inventor furthers investigate small weighbridge instrument, and especial manufacture goes out that a kind of cost is low, output is more stable
Thus the small weighbridge instrument of New-type mould revolution, this case produce.
Utility model content
The purpose of this utility model is to provide a kind of New-type mould revolution small weighbridge instrument, and it has, and device is few, small power consumption,
Cost is low and the characteristics of stability is high.
To achieve these goals, the technical solution of the utility model is as follows：
A kind of New-type mould revolution weighbridge instrument, including a mould revolution terminal box and a small weighbridge display instrument of numeral；It is described
Mould revolution terminal box includes four AD conversion chips, a MCU and one 485 chips, and four AD conversion chips connect with MCU
Connect, the chip of MCU connections 485,485 chip connects the small weighbridge display instrument of numeral by 485 order wires.
After such scheme, during utility model works, four AD conversion chips difference of mould revolution terminal box is external
One simulation weighing sensor, four AD conversion chips distinguish external simulation weighing sensor by it and obtain weight simulation letter
Number, then above-mentioned analog signal is switched to the unified transmission of data signal to MCU processing by four AD conversion chips, obtains weight
After data the small weighbridge display instrument of numeral is sent to by 485 chips through its order wire.
The beneficial effects of the utility model are：The utility model is only with 1 MCU and 1 485 chip and 4 AD compositions
Mould revolution terminal box, the processing after signal digitlization is completed by mould revolution terminal box, device compares conventional digital weighbridge instrument
Greatly reduce, cost is minimized, and signal transacting is fast, small power consumption, and the utility model has abandoned traditional analog smallly simultaneously
The shortcomings that pound instrument, by mould revolution, avoid the situation of jitter, thus the utility model had digital sensor concurrently can
The advantages of device cost used in the advantages of leaning on, easily adjusting and analog sensor is low.

Label declaration
Mould revolution terminal box 1, the chip 13 of AD conversion chip 11, MCU12,485, the small weighbridge display instrument 2,485 of numeral are logical
Believe line 3.
Embodiment
As shown in figure 3, the small weighbridge instrument of a kind of New-type mould revolution that the utility model discloses, including a mould revolution terminal box
1 and the small weighbridge display instrument 2 of numeral；Mould revolution terminal box 1 includes four AD conversion chips 11, a MCU12 and one 485 cores
Piece 13, four AD conversion chips 11 are all connected with MCU12, and the chip 13 of 485 chip of MCU12 connections 13,485 is connected by 485 order wires 3
Connect the small weighbridge display instrument 2 of numeral.
Utility model works process is：Four AD conversion chips 11 of mould revolution terminal box 1 distinguish an external simulation
Weighing sensor, four AD conversion chips 11 distinguish external simulation weighing sensor by it and obtain weight analog signal, so
Above-mentioned analog signal is switched to the unified transmission of data signal to MCU12 processing by four AD conversion chips 11 afterwards, obtains weight
After data the small weighbridge display instrument 2 of numeral is sent to by 485 chips 13 through its order wire.
It should be noted that the processing of mould revolution signal transacting and MCU to data signal is existing processing method.
It is a kind of small weighbridge instrument of New-type mould revolution of the utility model below with traditional analog weighbridge instrument and pure digi-tal
Pound instrument function contrast chart：
Specific embodiment of the utility model is these are only, not to the restriction of the scope of protection of the utility model.It is all according to
The equivalent variations that the mentality of designing of this case is done, each fall within the protection domain of this case.
