Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail。
As shown in Figure 1, thermometer and biosensor assay table apparatus outline drawing, it includes housing 1, connects the industrial computer 3 being connected with instrument 2 communication in order to the instrument 2 shown for sensor, housing 1 adopts aluminum alloy materials to make, there is the effect that waterproof is antirust, housing 1 is provided with instrument 2 and is mainly ammeter and voltmeter, and there is interface and the button of multiple wiring。Instrument 2 can adopt RS485 communication to be connected with industrial computer 3。
As shown in Figure 2, this testing stand also includes the temperature chamber device 4 placing also simulated environment temperature for sensor, described temperature chamber device 4 includes water bath 41, it is arranged at the stirring motor 42 bottom water bath 41, described water bath 41 is connected to ramp cycle water pipe 43, described ramp cycle water pipe 43 is provided with the circulating pump 44 providing Water circulation hydrodynamics and the heater 45 of watering cycle offer heat, described water bath 41 is also associated with down cycles water pipe 46, described down cycles water pipe 46 is provided with provides the storage tank 47 of cold water and for reclaiming the collection box 48 of warm water for water bath 41。Water outlet place at storage tank 47 is also connected to adjustment valve 6, it is possible to regulate valve 6 with this and water outlet of storage tank 47 is controlled。Thermometer 5 it is additionally provided with in water bath 41。Collection box 48 is also attached on ramp cycle water pipe 43 and controls the water yield of collection box 48 by regulating valve 6。Thermometer 5 can be diesel fuel temperature meter 5 or other。Being additionally provided with polyurethane insulation coating 8 in water bath 41, polyurethane insulation coating 8 can effectively maintain the temperature of water bath 41。
Its mentality of designing is as follows: be easy to temperature controlled environment to build, water temperature is adopted to carry out the simulation of environment, it is because specific heat of water and holds bigger, adopt heater 45 that ramp cycle water pipe 43 is heated, keep so that water absorbs heat, again through circulating pump 44 by continuous for the water in water bath 41 heat cycles, thus after reaching the temperature value needed, just stop heating, so that the water temperature in water bath 41 is relatively stable, it is provided with blender in the bottom of water bath 41, such that it is able to the middle water of water bath 41 is sufficiently stirred for, make water temperature can ratio more uniform, identical temperature is may be in when the temperature sensor 7 of test is positioned over the diverse location in water bath 41 time, temperature deviation is little, test more accurate, simultaneously in order to control the water temperature in water bath 41, control mode from low temperature to high temperature is by ramp cycle water pipe 43 is heated, so that water temperature rises to the temperature of setting, in time needing the water of high temperature is lowered the temperature, close the function of ramp cycle water pipe 43, can pass through to open down cycles water pipe 46, by releasing the cold water in storage tank 47, cold water and hot water are sufficiently mixed, decline thus realizing temperature, and unnecessary warm water is reclaimed by collection box 48, regulate and control is quite convenient to, and efficiently。Heater 45 can adopt thermostatic heater 45, it is possible to achieve adds being automatically adjusted of heat。Thermometer 5 can temperature conditions in Real-time Feedback water bath 41, it is possible to provide reference for testing equipment。For the purpose reaching to save that recycles to water resource, the warm water that recovery comes can provide hot water for ramp cycle water pipe 43, such that it is able to reduce the heat time heating time of heater 45, thus effectively save electric energy。
As shown in Figure 3, housing 1 is additionally provided with the testing circuit A for detecting temperature sensor 7 quality, described testing circuit A include the detection interface A1 for connecting temperature sensor 7, in order to judge the on-off circuit A2 of temperature sensor 7 signal, in order to regulate the potentiometer Rp of preset temperature, in order to the display lamp LED of indicating operating status。On-off circuit A2 includes audion one T1, audion two T2, audion three T3, resistance one R1, resistance two R2, resistance three R3；Audion one T1 base stage connects detection interface A1, and colelctor electrode connects power Vcc, and emitter stage passes through resistance one R1 ground connection；The colelctor electrode of audion two T2 connects power Vcc, the node of base stage connecting triode one T1 and resistance one R1, grounded emitter by resistance three R3；The colelctor electrode of audion three T3 connects power Vcc by display lamp LED；The colelctor electrode of base stage connecting triode two T2, grounded emitter；The colelctor electrode of resistance two R2 one end connecting triode three T3, the base stage of the other end online audion two T2。
The operation principle of above-mentioned circuit is: when ambient temperature is below design temperature, and audion one Tl turns on。Audion two T2 is also switched on。Its collector voltage is at below 0.3V, and therefore audion three T3 cut-off, display lamp LED does not work。If ambient temperature rises, then the voltage of temperature sensor 7 output raises, and the base voltage of such audion one Tl will raise, owing to audion one Tl is PNP type triode, so audion one Tl can end。The base stage of audion two T2 can not get operating current and is also switched off。Its collector voltage raises, and makes audion three T3 saturation conduction, and at this moment display lamp LED lights。
Experimental procedure: regulator potentiometer Rp makes that its resistance is descending to be gradually changed, till display lamp LED does not just work。Now promote the ambient temperature of temperature sensor 7。Can see after several seconds that display lamp LED lights。Adjusting ambient temperature makes temperature sensor 7 ambient temperature decline, and display lamp LED again can automatic distinguishing a little while。The resistance of regulator potentiometer Rp, thus it is possible to vary the ambient temperature that display lamp LED is required when lighting。
Adopt testing circuit A that temperature sensor 7 carries out quality detection, such that it is able to improve detection speed, if bad temperature sensor 7 can directly judge, such that it is able to accelerate detection efficiency, by display lamp LED, the state of temperature sensor 7 is indicated, more intuitively。Circuit structure is simple, and components and parts are few, more miniaturization, and the space taken is few, it is simple to install。
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model。
