Embodiment
Below in conjunction with accompanying drawing the present invention is done further elaboration.
A kind of embodiment of the present invention provides a kind of Internet of Things communication means, is applied to communicate by letter between data concentrator and the terminal equipment in the Internet of things system, and with reference to shown in Figure 1, described method is carried out according to following step:
Steps A, internet-of-things terminal equipment normality are resting state, and it is set in to wake up behind the unit interval and initiatively sends the signal of reporting for work to data concentrator;
Fig. 2 shows internet-of-things terminal equipment and in the unit interval, sends signal and the circulation that receives signal; With reference to shown in Figure 2; The inventor is in the experiment of carrying out; Tester networking terminal equipment is 4 hours in the time interval of sending the signal of reporting for work to data concentrator; Therefore can be preferred embodiment of the present invention with regarding as after following two steps combines with it, but also need, come specifically to confirm that the transmission of waking up of internet-of-things terminal equipment reports for work time interval of signal according to the concrete purposes of internet-of-things terminal equipment and the difference in functionality of required its realization.
Step B, data concentrator check after receiving the signal of reporting for work whether the untreated information of this terminal equipment is arranged in its storage inside content, if any promptly in Preset Time, sending work order to this terminal equipment;
Step C, internet-of-things terminal equipment are handled after receiving the work order that comes from data concentrator immediately, dispose and after data concentrator sends feedback information, get into resting state.
Definite says; Accompanying drawing 1 shows central server carries out overall process from exchanges data to the internet-of-things terminal device A; Comprised the execution of above-mentioned steps A to step C whole steps in this process, what also need describe is that above-mentioned steps A can make the step of instantaneous completion to step C; Between each step the small time interval or the time interval of nothing can only be arranged; Therefore should above-mentioned steps A be regarded as to step C is three different steps, and under the part situation, steps A can be merged into the step of an Internet of Things operation to step C.
And stated out a kind of situation of data concentrator after receiving the signal of reporting for work that comes from internet-of-things terminal equipment among the above-mentioned step B; And the another kind of situation of data concentrator after receiving the signal of reporting for work that comes from internet-of-things terminal equipment is after data concentrator is being received the signal of reporting for work that comes from internet-of-things terminal equipment among the step B; As check and do not find the untreated information of this terminal equipment in its storage inside content; Then in Preset Time, send the dormancy instruction to this terminal equipment, terminal equipment carries out resting state immediately after receiving the dormancy instruction.This kind situation also can be combined to form another kind of the present invention to step B with above-mentioned steps A and be similar to preferred embodiment arranged side by side.For the Preset Time of mentioning several times in the aforementioned content of the present invention, as a kind of comparatively preferred embodiment of the present invention, can be set to 5 seconds by aforementioned Preset Time, the Preset Time that the definite data concentrator of saying so sends work order or dormancy instruction is 5 seconds.
Inventor of the present invention is according to the various data that drawn in the experiment; To in the above-mentioned steps to the matching relationship between internet-of-things terminal equipment and the data concentrator; And optimization has in various degree been carried out in the setting of the various time intervals and Preset Time; With the present invention in actual motion several kinds of situations that can relate to be described below: internet-of-things terminal equipment gets into resting state after the unit interval after data concentrator sends the signal of reporting for work in the described steps A, and should the unit interval greater than the Preset Time of data concentrator among the step B to internet-of-things terminal equipment transmission work order.In conjunction with inventor's experimental data, get into resting state after internet-of-things terminal equipment 7 seconds after data concentrator sends the signal of reporting for work in the more preferably described steps A.
And according to the content of above-mentioned unit interval; In conjunction with concrete step of the present invention; Also having situation is that internet-of-things terminal equipment does not receive any instruction that comes from data concentrator after the unit interval after data concentrator sends the signal of reporting for work in the described steps A; Then get into resting state automatically; And should the unit interval send the Preset Time of work order at least to internet-of-things terminal equipment greater than data concentrator among the step B; The experimental data that combines the inventor does not here equally receive after internet-of-things terminal equipment 6 seconds after data concentrator sends the signal of reporting for work in the more preferably described steps A and comes from the data concentrator signal, then gets into resting state automatically.
According to the above-mentioned technology contents of the present invention, make its can be arbitrarily and above-mentioned steps A make up to step C, and then be transformed to more preferred embodiment of one or more the present invention.
The above-mentioned afterwards below various time intervals of mentioning or unit interval are example; Various dormancy condition setting to internet-of-things terminal equipment in the Internet of Things communication means of the present invention are described; Internet-of-things terminal equipment sends in 5 seconds behind the signal of reporting for work; Data concentrator promptly can send work order or dormancy instruction to it, and as also not receiving any signal instruction that comes from data concentrator above internet-of-things terminal equipment after 5 seconds, it can get into resting state automatically after 6 seconds so.Certainly also can be according to another dormancy condition that is provided with in the internet-of-things terminal equipment; Promptly after 7 seconds after data concentrator sends the signal of reporting for work; Only if receive the work order that comes from data concentrator again before this, not so get into resting state without exception automatically.
Above-mentioned Internet of Things communication means is applied in the Internet of Things control system of intelligent gas meter, and communicates through wireless transmission between data concentrator and the internet-of-things terminal equipment, and wireless transmission method can be selected GPRS, bluetooth, Wi-Fi and ZigBee etc.
And above-mentioned terminal equipment is an intelligent gas meter, and intelligent gas meter communicates through CPU control module and data transmission module and data concentrator; And through the CPU counter triggers CPU control module is waken up, waken up back CPU control module and send the signal of reporting for work to data concentrator through data transmission module; Apply the present invention in the Internet of Things control system that intelligent gas meter forms, untreated information is for closing valve information and charging information among the so described step B.
The terminal equipment most of the time in the Internet of Things communication means of the present invention is in resting state; Through the time interval of science setting; The timing automatic entering operating state of waking up; Initiatively with data concentrator communicates and exchanges data, the time that guarantees work every day of internet-of-things terminal equipment is in controllable scope, simultaneously in the assurance receiving sensitivity through wireless mode; Greatly reduce the odd-numbered day power consumption of terminal equipment, belong to the battery life of the internet-of-things terminal equipment of equipment for no reason at all thereby significantly improve.
