The communication channel of threshold value is spent, and the communication channel by being selected counts accordingly to all described send from equipment
According to read requests；
Step S3, it is described to receive the data read request from equipment, and corresponding real time data is passed through into the communication channel
It is sent to the main equipment；
Step S4, the main equipment according to acquisition moment of the real time data received, by it is all from it is same it is described from
The real time data of equipment is fitted the change curve to form the association real time data, and is shown.
9. collecting method as claimed in claim 8, which is characterized in that the step S3 is specifically included:
Step S31, it is described to acquire the real time data from equipment, and a corresponding time is added to each real time data
Information is stabbed, to indicate the acquisition moment of the real time data；
Step S32, it is described to save the collected real time data and the corresponding timestamp information from equipment；
Step S33, it is described receive the data read request from equipment after, by the real time data being saved and corresponding
The timestamp information be sent in the main equipment.
10. collecting method as claimed in claim 9, which is characterized in that described each from equipment in the step S33
After having sent the real time data being saved, the real time data sent is deleted.
11. collecting method as claimed in claim 8, which is characterized in that in the step S3, it is described from equipment every one
Preset wake-up period is waken up, and receives the data read request.
12. collecting method as claimed in claim 9, which is characterized in that in the step S4, the main equipment is according to right
The timestamp information for answering the real time data judges the acquisition moment of each real time data；
The main equipment is all from the same real time data from equipment by what is received according to the acquisition moment
It is arranged successively and is fitted to the corresponding change curve and export.
13. collecting method as claimed in claim 9, which is characterized in that in the step S4, formed by fitting corresponding
The change curve after, the main equipment continues to the real time data, and according to the time of the correspondence real time data
Information is stabbed, judges the acquisition moment of each real time data；
The main equipment by the acquisition moment for the real time data being currently received with upper one receive from same institute
It states and is compared from the acquisition moment of the real time data of equipment, and by earlier than upper one real-time number of the acquisition moment
According to real time data be judged as historical data；
The main equipment updates the corresponding change curve for being fitted formation according to the historical data, and is shown
Show.
14. the collecting method as described in any one of claim 8-13, which is characterized in that the main equipment is set to
In one mobile terminal.
