Device, prompt messages is sent to by way of mail mail server.
Further, for improving the accuracy to terminal control, described step S30 includes：
The intensity of the audio signal that described terminal acquisition extracts, and determine that audio number intensity is more than the effective of pre-set threshold value
Audio signal；
Described terminal is according to the mapping relations between the frequency of default audio signal and operational factor, or default sound
Mapping relations between the frequency of frequency signal and regulation rule, obtain the operational factor corresponding to the frequency of audio signal determining
Or regulation rule.
In the present embodiment, the sound of setting on the audio playing apparatus worn due to personnel to be detected or measurement equipment to be checked
The audio signal of the predeterminated frequency that frequency playing device is play may penetrate cladding system, then the audio signal extracting in terminal
When intensity is more than default threshold values, acquiring unit runs according to default first operational factor, or according to the default first tune
Whole rule carries out parameter adjustment, to ensure the accuracy that terminal is controlled.
Further, for improving the accuracy to terminal control, described step S40 replaces with step：
When the frequency of the audio signal extracting comprises all default frequencies, described terminal is according to the operation getting
Parameter is run or is carried out parameter adjustment according to the regulation rule getting, and sends alarm letter to default communication terminal
Breath.
For example, the audio playing apparatus such as baby's wearable sounding foot ring, sounding bracelet, sounding belt and sounding medicated cap,
And the frequency of audio signal play of sounding foot ring, sounding bracelet, sounding belt and sounding medicated cap be respectively 17K,
17.5K, 18K, 18.5K, then comprising frequency in the mixed audio signal that terminal detects is 17K, 17.5K, 18K, 18.5K
During audio signal, illustrate that the quilt of lid with baby is raised completely, now, can to default communication eventually for preventing baby from catching a cold
End sends prompt messages；Or, the first audio frequency is set at the edge needing capped measurement equipment to be checked and middle part and broadcasts
Put device, the second audio playing apparatus, the 3rd audio playing apparatus and the 4th audio playing apparatus, first to fourth audio frequency is broadcast
Put device respective frequencies and be respectively 17K, 17.5K, 18K, 18.5K, then comprise frequency in the mixed audio signal that terminal detects
When rate is the audio signal of 17K, 17.5K, 18K, 18.5K, illustrate that the covering on measurement equipment to be checked is raised completely, can be to pre-
If communication terminal send prompt messages.
It will be appreciated by persons skilled in the art that extracting when comprising all default frequencies, terminal can only to
Default communication terminal sends prompt messages, and processing unit can control terminal closedown.
