Description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated：
Fig. 1 is the appearance diagram of portable WBGT Index Instruments provided by the invention；
Fig. 2 is the logical construction schematic diagram of portable WBGT Index Instruments provided by the invention.
In figure：1- shells, 2- dry-bulb temperature sensors, 3- natural wet bulb temperatures sensor, 4- black ball temperature sensor, 5-
Instrument switch, 6- displays, 7- time switches, 8- change-over switches, 9- processors, 10- data storages, 11-USB interfaces.
Specific implementation mode
Fig. 1 and Fig. 2 respectively illustrates the appearance and logical construction of portable WBGT Index Instruments provided by the invention.
As Fig. 1 and Fig. 2 jointly shown in, portable WBGT Index Instruments provided by the invention, including：It shell 1 and is respectively set
The dry-bulb temperature sensor 2 at the top of shell 1, natural wet bulb temperature sensor 3, black ball temperature sensor 4, in 1 side of shell
It is provided with instrument switch 5, is arranged in the display 6 on 1 surface of shell, the time switch 7 below display 6, is arranged in shell
The change-over switch 8 of 1 side of body, the processor 9 being separately positioned in shell 1, data storage 10 and it is arranged in 1 bottom of shell
Usb 11.
One end of instrument switch 5 is sensed with dry-bulb temperature sensor 2, natural wet bulb temperature sensor 3, black ball temperature respectively
Device 4 connect, the other end access power supply, instrument switch 5 for control dry-bulb temperature sensor 2, natural wet bulb temperature sensor 3,
Black ball temperature sensor 4 is turned on and off.
Dry-bulb temperature sensor 2, natural wet bulb temperature sensor 3 are selected with black ball temperature sensor 4 by change-over switch 8
Property access processor 9；When change-over switch 8 selects outdoor gear, by dry-bulb temperature sensor 2, natural wet bulb temperature sensor 3 with
Black ball temperature sensor 4 is all connected with processor 9, when change-over switch 8 selects outdoor gear, by natural wet bulb temperature sensor
3, black ball temperature sensor 4 is connected with processor 9, is equivalent to and is closed dry-bulb temperature sensor 2.When operating personnel works, root
Change-over switch 8 is adjusted to indoor gear or outdoor gear according to the place of required detection.Change-over switch 8 is the prior art, therefore herein no longer
It repeats.
For time switch 7 using the general purpose timer in STM32 type microcontrollers, time switch 7 connect 9 with processor, uses
In starting the WBGT indexes that processor 9 calculates current environment according to preset equilibration time, current environment is indoor environment or room
External environment.
According to actual job time and expected contact heat radiation situation of change, when time switch 7 is preset with different balances
Between come for operation personnel selection, such as 5min, 10min, 30min and 1h, when selecting 5min, after timing to 5min, at startup
Manage the WBGT indexes that device 9 calculates current environment.Can be seen that the equilibration time in the present invention by above-mentioned example refers at startup
The count down time of device 9 is managed, each selected equilibration time computes repeatedly the WBGT indexes of current environment.
Processor 9 uses the universal microcontroller of 80C51 formulas, for being passed according to dry-bulb temperature sensor 2, natural wet bulb temperature
The temperature data that sensor 3, black ball temperature sensor 4 transmit calculates the WBGT indexes of indoor environment or outdoor environment.
Processor 9 access dry-bulb temperature sensor 2, natural wet bulb temperature sensor 3, black ball temperature sensor 4, lead to
It crosses following formula and calculates WBGT indexes：
WBGT=wet-bulb temperature (DEG C) × 0.7+ black ball temperature (DEG C) × dry-bulb temperature × 0.1 0.2+；
Ball temperature sensor 3, black ball temperature sensor 4 are only accessed in processor 9, calculating WBGT by following formula refers to
Number：
WBGT=wet-bulb temperature (DEG C) × black ball temperature × 0.3 0.7+.
Processor 9 is averaged according to the equilibration time of selection using time weight, and to calculate time weight average for WBGT exponential formulas
WBGT indexes：
Data storage 10 is sent to after processor 9 calculates WBGT indexes to be stored.
Data storage 10 uses M25P32 type Nor flash storages, capacity 32Mb, data storage 10 to pass through
Data line is connect with processor 9, for being stored to 9 calculated WBGT indexes of processor.Data storage 10 also passes through
Spi bus is connect with display 6, and 9 calculated WBGT indexes of processor, which are sent to display 6, to be shown, display is passed through
Device 6 can real time inspection WBGT indexes variation.Display 6 uses UG-2832 type LCD MODULEs.
Usb 11 is connect by data line with data storage 10, for externally providing USB interface service, operation people
Member can export the result of calculation of the processor 9 stored in data storage 10 by the usb 11.
