Rate is hit less than 5%.
Main frame calculates the quantity of many moisture probes once obtaining after the address information of all many moisture probes, how wet sets up
Spend the address list of probe and for each many moisture probe storage allocation, then scanned successively respectively according to the address list of foundation
Individual probe (being the address transmission request data into list), obtains real time data, until epicycle poll-final.Each poll
Cycle can set, scope be 1s~12 hour, it is flexible and convenient to use.
Temperature and humidity filed device, system and temperature and humidity filed method that the present invention is provided, can be real by upper computer software
The now remote control to temperature and humidity filed device and management, can be achieved following function：
1st, the inquiry of humiture real time data, the average value inquiry of each many moisture probe；
2nd, the inquiry of the humiture information of temperature and humidity filed device collection and its related information, including stored record number, deposit
The information such as storage interval and battery allowance；
3rd, historical record is obtained with deleting, and can obtain the record of most 60000, and support to wipe whole writing functions；
4th, system is set, including the parameter such as equipment time, device number, memory gap；
5th, homing device.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention described should be defined by scope of the claims.
