Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example：
A kind of synchronic gas acquisition method that the present invention is provided, there is a variety of collecting devices in certain area, specifies any
One collecting device is the first collecting device, and other collecting devices are the second collecting device, and the first collecting device is main equipment, the
Two collecting devices are slave unit, when there was only two collecting devices in this region, and the second collecting device quantity is adopted to remove first
Collect another of equipment, when there are many collecting devices in this region, the second collecting device is other multiple devices.Set the
The timing wake-up time of one collecting device and the second collecting device, it is in the first collecting device and the second collecting device and wakes up shape
State and the alternate state of resting state, make equipment be in wake-up states when that need not gather gas concentration, reduce equipment
Power consumption, saves operating cost；Second collecting device and the first collecting device are located automatically after the duration of timing wake-up time
In wake-up states, the timing wake-up time of the first collecting device is T1, the second collecting device timing wake-up time was T2, first adopts
Integrate equipment in the time in a dormant state as T1Afterwards, the first collecting device is in wake-up states, and the second collecting device is in not
Dormancy state for time is T2Afterwards, the second collecting device is in wake-up states.
As shown in figure 1, this method has following steps：
Step 10：First collecting device gathers gas concentration data；When first collecting device is in wake-up states, first adopts
Collect equipment collection gas concentration data.
Step 20：First collecting device judges whether gas concentration data exceed gas concentration threshold, if so, continuing step
30, if it is not, then the first collecting device goes successively to resting state, next wake-up states are waited, when the second collecting device is located again
When wake-up states, step 10 is continued executing with.
Step 30：First collecting device sends synchronous acquisition order to the second collecting device, and the first collecting device passes through wide
Multicast data passage sends synchronous acquisition order data to the second collecting device, and the equipment in the second collecting device can be received
The synchronous acquisition order sent from broadcast channel；Synchronous acquisition order includes lead code, synchronous code, command frame, and lead code is
Binary coding, the preamble transmissions time is T3, make T3More than 2T2, when the lead code is sent to the second collecting device, second
If collecting device is in a dormant state, the second collecting device dormancy time passes through T2It can still be received when afterwards into wake-up states
The lead code sent to the first collecting device.
Step 40：Second collecting device receives being in the lead code that the first collecting device is sent, the second collecting device
The equipment of wake-up states receives the lead code that the first collecting device is sent, and lead code can be alternatively two for binary alternate code and enter
Loop-free any code body of system, as shown in Fig. 2 the transmission time T of lead code3Starting time Q1 can be divided into, during the end of transmission
Between point be Q, preamble transmissions time T3 is transmission end time point Q and starting time Q1 difference, Q2, Q3, Q4, is lead code
Random time point during transmission time, is not All Time point, before the first collecting device is sent to the second collecting device
During leading code, the equipment in wake-up states can immediately receive and can receive leading since starting time Q1 in the second equipment
Equipment in code, the second collecting device in a dormant state is again introduced into wake-up states after timing wake-up time duration, i.e.,
Lead code is received since random time point between Q1-Q, such as lead code is received since time point Q2 or Q3 or Q4, again
It is to start to receive the lead code time to lead code to preceding for the reception time of lead code to wake up the equipment for entering wake-up states
Leading code transmission end time point Q period, therefore the end time of all devices reception lead code in the second collecting device
It is identical.
Step 50：Second collecting device receives the command frame that the first collecting device is sent, when the second collecting device is received
During the synchronous code that the first collecting device is sent, the second collecting device, which receives lead code, to be terminated, as shown in Fig. 2 before synchronous code is located at
After leading code, synchronous code simultaneously before the command frame, and synchronous code be not belonging in lead code, step 40 in different time points
When the equipment for receiving lead code receives synchronous code at time point Q, then the second collecting device terminates to connect lead code simultaneously
Receive, after the second collecting device receives the synchronous code of the first collecting device transmission and reception terminates, in the second collecting device
All devices receive immediately the first collecting device transmission command frame, if in step 40 in different reception lead codes
Equipment be not received by synchronous code, then the second collecting device still continues the reception to lead code, now second collection set
It is standby to receive the command frame of the first collecting device.
Step 60：Second collecting device is more in the second collecting device according to command frame synchronous acquisition gas concentration data
Platform equipment is according to command frame synchronous acquisition gas concentration data.
Step 70：First collecting device and the second collecting device send the gas concentration data of collection into background monitoring
After the heart, the second collecting device collection gas concentration data, the first collecting device and the second collecting device are by the gas collected
Concentration data is sent to gateway device, and gateway device sends gas concentration data to background monitoring center, background monitoring center
The concentration data of the gas with various in this region can be obtained simultaneously.
