Server 300 also sets up the correspondence mappings relation between locator data and water quality testing data, geographic position residing when making can determine to detect to each water quality testing data.Water quality detecting device 100 and intelligent terminal 200 normally carry out wireless connections by in-plant communication (Bluetooth communication as escribed above, BLE communicate etc.), therefore also can know the geographic position residing for water quality detecting device 100 by the locator data of intelligent terminal 200.Therefore, the locator data of intelligent terminal 200 also can be understood as the locator data of water quality detecting device 100.

Server 300 can determine the first geographic area according to locator data.After server 300 obtains locator data, centered by the coordinate that can identify by locator data, radius be r border circular areas in geographic area be the first geographic area.

After server 300 determines the first geographic area, obtain the first mean value of the water quality testing data in the first geographic area.Because each water quality testing data has locator data corresponding, therefore in the water quality testing data in the past stored, server 300 can obtain locator data and be in water quality testing data in the first geographic area, then calculates its mean value using as the first mean value.First mean value of the water quality testing data in the first geographic area, can be the mean value of the water quality testing data in some time periods, can be such as the mean value of the water quality testing data detecting the same day and stored, or the mean value of the water quality testing data detecting in a few hours recently and store.

After server 300 obtains the first mean value, water quality testing data DATA and the first mean value are contrasted, the difference according to water quality testing data DATA and the first mean value sends the first information to intelligent terminal 200.The first information is for characterizing water quality situation.By determining the first geographic area, the water quality testing data DATA that water quality detecting device 100 this time can be detected and the water quality testing data mean value of periphery contrast, the water quality situation information (first information) that user can export according to intelligent terminal 200 is directly acquainted with the contrast situation of oneself water quality and periphery water quality, thus oneself water quality goes wrong or periphery water quality all has problems to facilitate user to judge.

Such as, server 300 stores multiple history water quality testing data, according to the locator data corresponding with these history water quality testing datas, determine the region A in circumference 2 kilometers, the mean value (i.e. the first mean value) of the history water quality testing data in the A of zoning is 240ppm.If the water quality testing data DATA accessed by server 300 is about 300ppm, obviously more much bigger than the mean value of the history water quality testing data of region A, prove that the water body that water quality detecting device 100 this time detects may have occurred water pollution, may go wrong with drainage facility in user family, therefore server 300 sends the first information to intelligent terminal 200.

In order to make water pollution extremely can to knowing in time and processing, in the present invention, when the difference of water quality testing data DATA and the first mean value is greater than the first predetermined threshold value, the output module of intelligent terminal 200 sends the first water quality warning information in response to the first information.Similar with terminal predetermined threshold value, the first predetermined threshold value can be user's sets itself, also can be that system presets.

Such as, first mean value is 240ppm, first predetermined threshold value is 50ppm, and water quality testing data DATA is 300ppm, the difference of water quality testing data DATA and the first mean value is 60ppm, exceeded the first predetermined threshold value, therefore intelligent terminal 200 responds the first information and sends the first water quality warning information.First water quality warning information can make user just directly can be known the contrast situation of water quality by intelligent terminal 200, such as the first water quality warning information can be " water quality that water-quality ratio has an area of in 2 kilometers is bad ", " this detects water quality TDS value is 300ppm, water quality TDS mean value in having an area of 2 kilometers is 240ppm " etc., and on the corresponding multiple position of electronic chart, mark history water quality testing data corresponding to this position simultaneously, make user comparatively can get information about water quality contrast situation, user can judge that may go wrong with drainage facility in family causes water degradation.Certainly, when the difference of water quality testing data DATA and the first mean value is less than the first predetermined threshold value, intelligent terminal 200 also can send the first water quality information in response to the first information, such as " water-quality ratio has an area of the water quality height 20ppm in 2 kilometers ", " this detects water quality TDS value is 300ppm, and the water quality TDS mean value in having an area of 2 kilometers is 280ppm " etc.

In a lot of situation, user has understood this water quality detected and has contrasted situation with the water quality in circumference 2 kilometers (zonule), also may wish that understanding exceeds the water quality situation of circumference 2 kilometers, i.e. more large regions scope (large regions), whether normal to understand this water quality detected further, or or large regions within the scope of water quality all there is exception.Therefore, through carrying out with the first mean value of water quality testing data in the first geographic area above after first time contrasts, enlarged area scope to carry out secondary contrast, then describing second time comparison process below.

After receiver module receives the first information, intelligent terminal 200 also provides the interface receiving user's input to carry out input operation for user in response to the first information, incoming event monitored by intelligent terminal 200 simultaneously.Intelligent terminal 200 is after recognizing the first incoming event, sending module sends the information continuing to detect to server 300, after server 300 receives the information continuing to detect, the second mean value of the water quality testing data in the second geographic area is determined according to locator data, water quality testing data DATA and the second mean value are contrasted, the difference according to water quality testing data DATA and the second mean value sends the second information to described intelligent terminal.Wherein the second geographic area covers the first geographic area completely, and also namely the first geographic area is in the second geographic area, and the second geographic area is larger than the first geographic area.

Server 300 can determine the second geographic area according to locator data.After server 300 obtains locator data, centered by the coordinate that can identify by locator data, radius be R border circular areas in geographic area be the second geographic area.Wherein, R is greater than above-mentioned r.

After server 300 determines the second geographic area, obtain the second mean value of the water quality testing data in the second geographic area.Because each water quality testing data has locator data corresponding, therefore in the water quality testing data in the past stored, server 300 can obtain locator data and be in water quality testing data in the second geographic area, then calculates its mean value using as the second mean value.Equally, second mean value of the water quality testing data in the second geographic area, can be the mean value of the water quality testing data in some time periods, can be such as the mean value of the water quality testing data detecting the same day and stored, or the mean value of the water quality testing data detecting in a few hours recently and store.

After server 300 obtains the second mean value, water quality testing data DATA and the second mean value are contrasted, the difference according to water quality testing data DATA and the second mean value sends the second information to intelligent terminal 200.Second information is for characterizing water quality situation.By determining the second geographic area, the water quality testing data DATA that water quality detecting device 100 this time can be detected contrasts with the water quality testing data mean value more wider than the first geographic area, the water quality situation information (first information) that user can export according to intelligent terminal 200 is directly acquainted with the contrast situation of oneself water quality and water quality on a large scale, thus oneself the water quality water quality on a large scale that goes wrong still all has problems to facilitate user to judge.

Such as, server 300 stores multiple history water quality testing data, according to the locator data corresponding with these history water quality testing datas, determine the region B in circumference 5 kilometers, the mean value (i.e. the second mean value) of the history water quality testing data in the B of zoning is 240ppm.If the water quality testing data DATA accessed by server 300 is about 300ppm, obviously more much bigger than the mean value of the history water quality testing data of region B, prove that the water body that water quality detecting device 100 this time detects may have occurred water pollution, may go wrong with drainage facility in user family, therefore server 300 sends the second information to intelligent terminal 200.

In order to make water pollution extremely can to knowing in time and processing, in the present invention, when the difference of water quality testing data DATA and the second mean value is greater than the second predetermined threshold value, after the receiver module of intelligent terminal 200 receives the second information that server 300 sends, output module sends the second water quality warning information in response to the second information.Similar with the first predetermined threshold value, the second predetermined threshold value can be user's sets itself, also can be that system presets.

Such as, the second mean value is 240ppm, and the second predetermined threshold value is 50ppm, and water quality testing data DATA is 300ppm, the difference of water quality testing data DATA and the second mean value is 60ppm, has exceeded the second predetermined threshold value, and therefore intelligent terminal 200 response sends the second water quality warning information.Second water quality warning information sends to intelligent terminal 200, user can be made just directly to know the contrast situation of water quality and water quality on a large scale by intelligent terminal 200, such as the first water quality warning information can be " water quality that water-quality ratio has an area of in 5 kilometers is bad ", " this detects water quality TDS value is 300ppm, water quality TDS mean value in having an area of 5 kilometers is 240ppm " etc., and on the corresponding multiple position of electronic chart, mark history water quality testing data corresponding to this position simultaneously, make user comparatively can get information about water quality contrast situation, user can judge that may go wrong with drainage facility in family causes water degradation.Certainly, when the difference of water quality testing data DATA and the second mean value is less than the second predetermined threshold value, intelligent terminal 200 also can send the second water quality information in response to the second information, such as " water-quality ratio has an area of the water quality height 20ppm in 5 kilometers ", " this detects water quality TDS value is 300ppm, and the water quality TDS mean value in having an area of 5 kilometers is 280ppm " etc.

Certainly, in certain embodiments, the water quality contrast more wider than the 3rd geographic area can also next be carried out, or the water quality contrast continuing the second geographic area etc., again repeat no more.

Or, in a lot of situation, user has understood this water quality detected and has contrasted situation with the water quality in circumference 2 kilometers (zonule), may also wish to understand the water quality situation detected in similar time section within the scope of neighboring area, whether normal to understand this water quality detected further.After all, first mean value used during contrast is the mean value of the water quality testing data in some time periods, can be such as the mean value of the water quality testing data detecting the same day and stored, or the mean value of the water quality testing data detecting in a few hours recently and store, time span is comparatively large, and within the scope of neighboring area, water quality may change in nearest one or two hour.Therefore, through carrying out after first time contrasts above with the first mean value of water quality testing data in the first geographic area, also the second time of water quality testing data in similar time within the scope of the water quality testing data DATA of this detection and neighboring area can be contrasted, then describe second time comparison process below.

After receiver module receives the first information, intelligent terminal 200 also provides the interface receiving user's input to carry out input operation for user in response to the first information, incoming event monitored by intelligent terminal 200 simultaneously.Intelligent terminal 200 is after recognizing the second incoming event, sending module sends the information continuing to detect to server 300, after server 300 receives the information continuing to detect, to determine in the 3rd geographic area according to locator data and the 3rd mean value of water quality testing data in preset period of time, water quality testing data DATA and the 3rd mean value are contrasted, the difference according to water quality testing data DATA and the 3rd mean value sends the 3rd information to intelligent terminal 200.Wherein, the 3rd geographic area can be identical with the first geographic area, and certainly in other embodiments, the 3rd geographic area can also be more greater or lesser than the first geographic area.In following description, the 3rd geographic area is the first above-mentioned geographic area.

Server 300 can determine the 3rd geographic area according to locator data.After server 300 obtains locator data, centered by the coordinate that can identify by locator data, radius be r border circular areas in geographic area be the 3rd geographic area.

After server 300 determines the 3rd geographic area, to obtain in the 3rd geographic area and the 3rd mean value of water quality testing data in preset period of time.Because each water quality testing data has locator data corresponding, therefore in the water quality testing data in the past stored, server 300 can obtain locator data and be in the 3rd geographic area and water quality testing data in preset period of time, then calculates its mean value using as the 3rd mean value.Preset period of time can be in nearest Preset Time, and such as, in nearest 1 hour, the 3rd mean value can be such as the mean value of the water quality testing data detecting in nearest 1 hour in the 3rd geographic area and store.

After server 300 obtains the 3rd mean value, water quality testing data DATA and the 3rd mean value are contrasted, the difference according to water quality testing data DATA and the 3rd mean value sends the 3rd information to intelligent terminal 200.3rd information is for characterizing water quality situation.By determining the 3rd geographic area, the water quality testing data mean value of the water quality testing data DATA that water quality detecting device 100 this time can be detected and the 3rd geographic area nearest time contrasts, the water quality situation information (the 3rd information) that user can export according to intelligent terminal 200 be directly acquainted with oneself water quality and the contrast situation of water quality in the 3rd geographic area nearest time, thus all a new problem arose for water quality among a small circle to facilitate user to judge to go wrong oneself water quality still.

Such as in first time water quality contrast, server 300 determines the region A in circumference 2 kilometers, and in the A of zoning, the mean value (i.e. the first mean value) of history water quality testing data that records is 240ppm the same day.If the water quality testing data DATA accessed by server 300 is about 300ppm, obviously more much bigger than the mean value of the history water quality testing data of region A, prove that the water body that water quality detecting device 100 this time detects may have occurred water pollution, therefore server 300 sends the first information to intelligent terminal 200.Then in the contrast of second time water quality, server 300 determines the region A in circumference 2 kilometers equally, the mean value (i.e. the 3rd mean value) of the history water quality testing data in the A of zoning in nearest 1 hour is 290ppm, the average value of the history water quality testing data of water quality testing data DATA obviously and in nearest 1 hour of region A is little, proving that region A (peripheral extent) interior water body just may be deteriorated in nearest 1 hour, is not because going wrong with drainage facility in user family.

In order to make water pollution extremely can to knowing in time and processing, in the present invention, when the difference of water quality testing data DATA and the 3rd mean value is greater than the 3rd predetermined threshold value, after the receiver module of intelligent terminal 200 receives the 3rd information that server 300 sends, output module sends the 3rd water quality warning information in response to the 3rd information.Similar with the first predetermined threshold value, the 3rd predetermined threshold value can be user's sets itself, also can be that system presets.

Such as, the 3rd mean value is 240ppm, and the 3rd predetermined threshold value is 50ppm, and water quality testing data DATA is 300ppm, the difference of water quality testing data DATA and the 3rd mean value is 60ppm, has exceeded the 3rd predetermined threshold value, and therefore intelligent terminal 200 response sends the 3rd water quality warning information.3rd water quality warning information sends to intelligent terminal 200, user can be made just directly to know the contrast situation of water quality and water quality on a large scale by intelligent terminal 200, such as the 3rd water quality warning information can be " water quality that water-quality ratio has an area of in 5 kilometers is bad ", " this detects water quality TDS value for 300ppm; the water quality TDS mean value in having an area of 5 kilometers is 240ppm " etc., and on the corresponding multiple position of electronic chart, mark history water quality testing data corresponding to this position simultaneously, make user comparatively can get information about water quality contrast situation.Certainly, when the difference of water quality testing data DATA and the 3rd mean value is less than the 3rd predetermined threshold value, intelligent terminal 200 also can send the 3rd water quality information in response to the 3rd information, such as " water-quality ratio has an area of the water quality height 10ppm in 5 kilometers ", " this detects water quality TDS value is 300ppm; the water quality TDS mean value in having an area of 5 kilometers is 290ppm " etc., user can just may be deteriorated by judging area A (peripheral extent) interior water body in nearest 1 hour, was not because going wrong with drainage facility in user family.
