Embodiment
The utility model is more specifically described in detail with reference to specific embodiment.
Embodiment
As shown in Figures 1 to 4.The utility model discloses one kind can show intelligent automatic meal selling machine, including Rice container
1st, (S types) weighing sensor 5, voltage amplifier and a/d converter, the LCD display circuit of 1 bottom of Rice container are arranged on；
Weighing sensor 5 produces electric signal due to being under pressure, which is admitted to after voltage amplifier amplifies
In a/d converter, and the conversion in A/D converter into horizontal electrical signal and digital signal, transformed digital signal are sent to
LCD display circuit, and show by LCD display 2 the remaining appetite data in Rice container 1；
The weighing sensor 5 is four, be symmetrically set in two of 1 bottom of Rice container it is diagonal on, one pair of which angle
Two weighing sensors 5 abut directly on the bottom of Rice container 1, another two diagonal weighing sensors 5 and Rice container bottom
Warm (thermal insulation) gasket of resistance is clamped between portion；The warm gasket of resistance is used to reduce the conductivity of heat between Rice container 1 and weighing sensor 5
Energy.They are connected into bridge architecture, have carried out temperature-compensating, to improve the accuracy of measurement.
The LCD display 2 is arranged at the top of 1 lateral wall of Rice container, passes through with the LCD display circuit of circuit board 4
Data cable 3 is connected.
The voltage amplifier uses AD603 type voltage amplification modules, and a/d converter uses AD736JPZ type AD conversion modules.
The weighing sensor 5 (resistance-strain type) uses diplopore beam type connection.
In Fig. 4.R1-R4 is four resistance strain gages, and R5, R6 and RPI collectively constitute part adjustment circuit.Before use, adjust
Section RPI can realize that the numerical value on LCD display is zero, so as to subtract the intrinsic weight such as Rice container, the numerical value for making display is appearance
Remaining appetite weight, realizes school zero in device.Resistance strain gage can be deformed after being under pressure, so that the resistance value hair of resistance
Changing, so that electric current changes, achievees the purpose that to show weight change.
In this sensor, resistance strain gage is attached on flexible member, when flexible member is subject to the effect of power to deform,
The foil gauge being attached to above also deforms therewith, causes resistance to change.
Measuring circuit can measure the change of strain sheet resistance and be transformed into the electric signal proportional to external force size and carry out
Output, that is, measure Rice container and wherein fill the quality of appetite.
, can be by it on the coupling nut of piston manometer during calibration load cell, the handwheel production of rotation pressure pump
Raw operating pressure, is transmitted to measurement piston, weighing sensor wiring makes pallet rise to defined scribe line position, by institute through working solution
Required pressure calibration interval.
Voltage amplifier and a/d converter use integration module, and small, superior performance, is easily disposed in circuit board.
Voltage amplifier uses AD603 type voltage amplifiers, it is by passive input attenuator, gain control interface and fixation
Gain amplifier three parts form.The signal of ladder type network input terminal is added in after overdamping, is exported by fixed gain amplifier,
When the connection of two pins of VOUT and FDBK is different, the gain ranging of amplifier can change, final to realize piezo-electric crystal
The potential for being under pressure and producing amplifies step by step, and the electric signal is gathered easy to a/d converter below.
A/d converter uses AD736JPZ type a/d converters, and this converter is mainly characterized by precision height, and its
Body carries output decoder, can directly drive LCD display show it is converted after signal.
A/d converter and LCD display are designed to the structure of a voltage tabular form, can be according to actual needs design flow
Journey.For example, the voltmeter of 300mV ranges is may be designed to, the weight change of corresponding one or two meal of change of voltmeter 1mV, so that directly
See ground and show remaining appetite in Rice container.
Remaining appetite in Rice container is directly displayed out by LCD display, understand in time easy to the person of getting food surplus and
Administrative staff are replenished in time.
As described above, it can preferably realize the utility model.
The embodiment of the utility model is simultaneously not restricted to the described embodiments, other are any without departing from the utility model
Spirit Essence with made under principle change, modification, replacement, combine, simplification, should be equivalent substitute mode, be included in
