As shown in figure 3, it is applied to main control device 200 the embodiment of the invention provides a kind of Network Fault Detecting method, it should
Main control device 200 is used to establish with multiple wireless data collection devices 100 and wirelessly communicate, to form wireless data acquisition network,
It the described method comprises the following steps.
Step S401: detecting and records wireless data collection device 100 and the time point of communication failure of communication failure.
Wherein, the wireless data collection device 100 of communication failure refers to fail and carries out the wireless data of data interaction and adopt
Collect equipment 100.
In practical applications, each wireless data collection device 100 can be set and periodically carry out data interaction, then, it is setting
Time fails to complete the wireless data collection device 100 of the as communication failure of wireless data collection device 100 of data interaction, should
Setting time is the time point of communication failure.Also it may be set under certain condition, refer to as administrative staff issue data acquisition
Each wireless data collection device 100 carries out data interaction under conditions of order, then, after administrative staff issue data acquisition instruction
The wireless data collection device 100 for failing completion data interaction is the wireless data collection device 100 of communication failure, administrator
Member issues the time point that the time point that data acquisition instructs is communication failure.
Step S402: it judges whether there is the continuous communiction frequency of failure and reaches the data acquisition of the first preset threshold and set
Standby 100, if it is present executing step S403: statistics continuous communiction frequency of failure within the same period reaches described first
100 total amount of wireless data collection device of preset threshold.
In the present embodiment, show that the wireless data for reaching the first preset threshold there are the continuous communiction frequency of failure is adopted in judgement
When collecting equipment 100, that is, startup separator diagnosis mechanism, this care diagnostic mechanism abandoned in the prior art only one in network 300
The direct processing mode of networking again when the device fails of certainty ratio, can effectively improve the timeliness of troubleshooting.
Wherein, fault diagnosis mechanism includes above-mentioned steps S403: statistics continuous communiction frequency of failure within the same period
Reach 100 total amount of wireless data collection device and step S404 of first preset threshold: judging that the wireless data is adopted
Whether collection 100 total amount of equipment reaches the second preset threshold, if reaching second preset threshold, thens follow the steps step
S405: detection each data acquisition that the continuous communiction frequency of failure reaches first preset threshold within the same period is set
In standby 100 with the presence or absence of for critical path by wireless data collection device 100, if there is for critical path by wireless data adopt
Collect equipment 100, then follow the steps S406: be detected as critical path by the wireless data collection device 100 whether failure.
Wherein, the first preset threshold and the second preset threshold can with flexible setting, such as: if main control device 200 and multiple
Wireless data acquisition network composed by wireless data collection device 100 is smaller, such as unit of cell, in order to improve failure prison
Timeliness is surveyed, the first preset threshold can be set as 3, then, in each wireless data collection device 100 being set in cell
There are the communication failure numbers of any wireless data collection device 100 to reach 3 times, i.e. startup separator diagnosis mechanism.Assuming that cell
In a minimum of 3 wireless data collection devices 100 in each family, the second preset threshold can be set as 3, then, master control is set
The continuous communiction frequency of failure reaches 3 wireless data collection devices 100 always within the same period in the standby 200 detection cell
Whether amount reaches 3 or more, may be a certain family or multiple family's integrated communications in the cell if reaching 3 or more
It goes wrong or some communication relay node goes wrong, at this point, first detecting whether that there are communication relay nodes, i.e. master control
Equipment 200 detect communication failure 3 wireless data collection devices 100 in the presence or absence of for critical path by data acquisition
Equipment 100, if there is for critical path by wireless data collection device 100, then be detected as critical path by the no line number
According to acquisition equipment 100 whether failure.
A kind of completely new fault diagnosis mechanism is provided in above scheme, it can be in more wireless data collection devices 100
Specific aim diagnosis is carried out when concentration breaks down, and exists for key in the wireless data collection device 100 of more communication failures
When the wireless data collection device 100 of routing, directly to for critical path by wireless data collection device 100 diagnose, and
It is non-that networking again directly is carried out to all wireless data collection devices 100 such as the prior art, so that being diagnosed to be as critical path
By wireless data collection device 100 break down when, only need to for critical path by wireless data collection device 100 carry out again
Failure can be solved in new connection, will not improve available to the networking again of wireless data collection device 100 that remaining is worked normally
Property.
If each wireless data that the continuous communiction frequency of failure reaches first preset threshold within the same period is adopted
Integrate in equipment 100 there is no for critical path by wireless data collection device 100, then follow the steps S407: judgement is in same a period of time
Between the continuous communiction frequency of failure reaches first preset threshold in section each wireless data collection device 100 do not break down.
Equally by among the above by taking wireless data acquisition network 300 composed as unit of cell as an example, the first preset threshold
It is 3, there are the communications of any wireless data collection device 100 in each wireless data collection device 100 being set in cell
The frequency of failure reaches 3 times, i.e. startup separator diagnosis mechanism.A minimum of 3 wireless data collection devices in each family in cell
100, the second preset threshold is set as 3, then, main control device 200 detects the continuous communiction mistake within the same period in the cell
It loses number and reaches 3 100 total amounts of wireless data collection device and whether reach 3 or more, it, may if reaching 3 or more
It is that a certain family or multiple family's integrated communications go wrong in the cell or some communication relay node goes wrong, this
When, first detect whether that there are communication relay nodes, i.e. 3 wireless data collection devices of the detection of main control device 200 communication failure
In 100 with the presence or absence of for critical path by wireless data collection device 100, if there is no for critical path by wireless data adopt
Collect equipment 100, then it is believed that certain families may occur to concentrate power-off in cell, communication failure, which is powered off, to be caused, rather than because of nothing
Line data acquisition equipment 100 breaks down, at this point, being then not necessarily to networking again.
It should be noted that the wireless data collection device 100 of outage area can communicate mistake in occurrence of large-area power-off
Lose, at this point, may include in the wireless data collection device 100 of communication failure for critical path by wireless data collection device
100, in that case, it can be determined that with the presence or absence of it is multiple for critical path by wireless data collection device 100 in same a period of time
Between section communication failure, if it is multiple for critical path by wireless data collection device 100 also may be used in same period communication failure
Determining that power cut-off incident occurs, communication failure, which is powered off, to be caused, rather than because wireless data collection device 100 breaks down, at this point, then
Without networking again.
If the same period continuous communiction frequency of failure reaches the wireless data collection device of the first preset threshold
100 total amounts are lower than second preset threshold, then follow the steps S408: detecting the continuous communiction frequency of failure respectively and reach described the
Whether each wireless data collection device 100 of one preset threshold breaks down.
When implementing, the second preset threshold is preferably set as 300 unit of minimal network in wireless data acquisition network,
Such as: among the above as unit of cell in composed wireless data acquisition network 300, if family is minimum unit in cell,
A minimum of 3 wireless data collection devices 100 in each family, that second preset threshold are 3.If small within the same period
It is 2 that the continuous communiction frequency of failure, which reaches 3 wireless data collection devices 100, in area, then illustrates it is not centainly for critical path
By wireless data collection device 100 break down or some family have a power failure, then 2 wireless datas of communication failure are adopted at this time
