Specific implementation mode
To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with
Good embodiment and attached drawing cooperation detailed description, are described as follows：
As shown in Figure 1,4 500ml reagent bottles and 1 2000ml reagent bottle be in a device according to several rows of row, according to this
The distributed thin film pressure sensor of the design feature and reagent bottle design feature of monitoring device, custom-made is also by several only
Vertical pressure sensor, which is arranged in a row, to be composed, this distributed thin film pressure sensor apparatus is positioned over reagent bottle bottom,
And each reagent bottle bottom is distributed an independent pressure sensing point, and sensing station is in reagent bottle bottom centre
Place, the weight for reflecting each reagent bottle that can be more sensitive and accurate.
Distributed thin film pressure sensor uses resistive pressure sensor principle, for testing sensor plane Vertical Square
To active force.Its two external lead is exactly a resistance, generally under the conditions of static (not being bent, do not exert a force), sensing
The resistance of device is very big, is more than 1M Ω.On the effective area of sensor after applied force, the resistance between 2 leads of sensor
Value may also change accordingly, and force is bigger, and resistance value is smaller.Then sensing is detected by accurate electronic signal detection circuit (Fig. 3)
The variation of device resistance value obtains force acting on transducer size by F-R curve graphs (Fig. 2), obtains corresponding force value, finally convert
Go out the residual capacity of corresponding reagent, and show on display unit in the controls, site operation personnel is facilitated to obtain in time
Reagent service condition, when the reagent surplus in reagent bottle is less than certain threshold value, prewarning unit is alarmed, and reminds work
Personnel add reagent, are provided conveniently for on-site maintenance.
In this monitoring device system, it is preferred that emphasis is how accurately qualitatively to grasp reagent service condition in real time.
It is described as follows：Since reagent is ceaselessly consumed in use, the amount of reagent in reagent bottle can also be sent out
Changing, field maintenance person need opening bottle cap and the cover of not timing to check the capacity of remaining reagent, not only operate numerous
It is trivial, maintenance difficulties are increased, and check when being easy to volatilization or dangerous harmful reagent, also cannot safely and effectively protected
Barrier.Therefore it needs to research and develop a kind of detection device that can need not in real time obtain reagent surplus information by manpower.
The utility model is facilitating equipment just using the automatic monitoring reagent surplus of distributed thin film pressure sensor apparatus
Normal operation and maintenance.Reagent surplus in reagent bottle is accurately effectively monitored in order to realize, selects pressure resistance type diaphragm pressure sensing
Device, the piezoresistive pressure sensor have high sensitivity, and low drifting, anti-flex performance is good and the good feature of wear-resisting property, and
And the design feature and reagent bottle design feature of this equipment are combined, allow 4 500ml reagent bottles and 1 2000ml reagent bottle setting
According to several rows of row in standby, a diaphragm pressure sensor is placed in each reagent bottle bottom, and sensing station is in reagent bottle
At bottom centre.This piezoresistive pressure sensor is semiconductor pressure sensitive semiconductor pressure resistance type sensors after by external force,
What the geometry of itself change almost without, but its lattice parameter changes, and influences energy gap energy gaps
Even very small change can all cause the prodigious change of carrier density, this finally causes the resistivity of material to occur
Change.In this weighing technique, the reagent bottle for filling reagent is put on piezoresistive pressure sensor, due to pressure sensor
When by ambient pressure, resistance changes as ambient pressure changes, and for microcontroller by the connection with AD converter, data are logical
Obtain real time resistance value after crossing the calculating and processing of microcontroller, so obtain sensor by external force value, treated, and value is
Then reagent surplus shows the value of this reagent surplus on liquid crystal display.With the operation of equipment, reagent is surplus
Surplus greatly improves work efficiency by equipment liquid crystal display real-time display, saves manpower.Acquisition methods are safely, just
It is prompt, reliable.
Implementation is further illustrated below by application method：Monitoring device is by being mounted in sampling system reagent bottle bottom
Distributed thin film pressure sensor, with sophisticated signal acquire computing circuit come calculate sensor real time resistance (R1_ sense
Device=(VCC/Vout) * Rf), and then force acting on transducer size is obtained, corresponding force value is obtained, the surplus of corresponding reagent is finally conversed
Covolume amount, and in real time show the reagent surplus in reagent bottle on display device liquid crystal display in the controls.
Site operation personnel can obtain the information of reagent surplus in time, and field maintenance person can in advance add according to device prompts information
Installed reagents avoid shutting down caused by reagent lacks, greatly improve working efficiency.
The core technology scheme of the utility model is the distributed thin film pressure sensor by customization, is monitored in real time
The surplus of reagent in reagent bottle, concrete structure, type and its distinct device, the device of each appliance arrangement used in the system
Between the equal without concrete restriction such as quantity, structure, shape, material, the size of connecting elements, can rationally be selected according to actual conditions
It selects.
