Description of drawings
Fig. 1 is an embodiment part section structural representation.
Fig. 2 is that Figure 1A is to view.
Fig. 3 is an embodiment electricity structural principle block diagram.
Number in the figure: 1 end cap, 2 battery compartments, 3 liquid crystal micro display chips, 4 circuit storehouses, 4-1 buckle closure, 5 Temperature Humidity Sensors, 6USB interface, 7 transparent covers, 8 warning LED display aperture.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Embodiment as shown in Figure 1, 2, cylindrical body and end cap 1 that the registering instrument housing is made up of battery compartment 2 and circuit structure storehouse 4 constitute, end cap 1 inboard is provided with battery contact electrode plate structure, and battery compartment is equipped with a standard ER14250 column type lithium battery, and battery compartment 2 surfaces are provided with liquid crystal micro display chip 3.It is the buckle closure 4-1 that axially is provided with that circuit storehouse 4 is provided with respect to cylindrical body.4 surfaces, circuit structure storehouse are provided with two humiture upper and lower limit warning LED lamp display aperture 8, Temperature Humidity Sensor 5 and USB interface 6.Surface, circuit storehouse is provided with the transparent cover 7 that covers the circuit structure storehouse and engage with cylindrical body, and transparent cover and cylindrical body grafting junction surface are provided with the O-ring seal (not shown).
As shown in Figure 3, circuit structure in the circuit storehouse comprises the MCU of the single-chip microcomputer C8051F320 formation that is integrated with A/D converter and USB controller and the EEPROM24LC256 storer of Microchip company, Temperature Humidity Sensor employing NTC type thermistor (R25 ℃=2K), the LED alarm lamp adopts and has a positive red and green color LED and an orange LED altogether, thermometric hygrometric circuit adopts the direct current wheatstone bridge in this enforcement, two output terminals of electric bridge connect the positive-negative input end of the inner integrated A/D converter of C8051F320 respectively, draw the humiture of actual detected by conversion, be stored to 24LC256 then.When humiture exceeds the predefined humiture upper limit or down in limited time, two kinds of LED make up flicker with different frequencies respectively under different alarm condition, specifically: green LED per second flicker 2 times: the humiture pen recorder is in the delayed startup stage; Green LED per second flicker 1 time: the humiture pen recorder does not exceed the warning bound just in normal recordings; Green LED and the flicker of orange LED per second 1 time: the humiture pen recorder is record, does not exceed the warning bound.But storer is full, and data can not be stored; Red LED per second flicker 1 time: current record is equal to or less than low alarm limit; Red LED and the flicker of orange LED per second 1 time: current record is equal to or less than low alarm limit, but storer is full, and data can not be stored; Red LED per second flicker 2 times: current record is equal to or higher than high alarm setting; Red LED and the flicker of orange LED per second 2 times: current record is equal to or higher than high alarm setting, but storer is full, and data can not be stored; Orange LED per second flicker 1 time: the humiture pen recorder is in holding state, the battery electric quantity deficiency.
