Configured according to the parameter of transmission unit 157, concurrently set the alarm limits of each water quality sampling parameter.User's (i.e. monitoring client) uses
Multichannel water quality monitoring system 1 is followed the steps below, in step S1：Water is filled in water sample flowing lumen body 113.First by water-supply-pipe
The water delivery magnetic valve 1113 on road 111 is opened, and water is input into water sample flowing lumen body 113 by water-supply-pipe 1111, and water fills up water
Sample circulation cavity 113.
In step S3：After previous step S1 fills up water in water sample flowing lumen body 113, water-supply-pipe 1111 continues water delivery,
And water is discharged by the drainpipe 115 on the top of water sample flowing lumen body 113, such water sample circulation collection module 11 carries out water sample circulation.
In step S5：Gather sensing unit 117 and sample frequency to control power supply list according to multiple water quality parameters of setting
The power supply of member 159, and then control multiple water quality parameter collection sensing units 117 to sample water.Wherein under normal circumstances,

Unit 157, and sampled data passes through the teletransmission of data transmission unit 157 to remote server.
In step S7：If judging sampled value without departing from setting value, repeat the above steps S5, carries out normal inspection sampling.
If judging, sampled value exceeds setting value, sends alarm and carries out second of water quality sampling.Wherein setting value for water dissolved oxygen amount,
PH value, temperature, chlorine residue, the safe range numerical value of turbidity or conductance, in other words, when the sampled value of water is fallen within the range of this, then water
There is not difference in matter, if the sampled value of water exceeds this scope, water quality is affected change.Between wherein normal inspection is sampled as
The multiple water quality parameter collection sensing units 117 of startup of having a rest property.When multiple water quality parameter collection sensing units 117 are detected,
Monitoring can just be started.When multiple water quality parameter collection sensing units 117 are without detection, then stop starting monitoring.It can so drop
Low electric energy power consumption.
In step S9：If judging, second of sampled value, without departing from setting value, returns to above-mentioned steps S7 judgement.If sentencing
Disconnected second of sampled value exceeds setting value, then automatically switches to continuous sampling pattern, and passed simultaneously through data transmission unit 157
Defeated alarm is to distally.In other words, the detection of sampled value judges whether double sampled value exceeds setting value to meeting foundation, if the
Double sampling value is normal value, then counts again, that is, counts and reset, and returns to normal inspection sampling.If double inspection
The sampled value of survey exceeds setting value, then is switched to continuous sampling pattern, to carry out the monitoring of continuation at once for water quality.It is above-mentioned
Mode be in order to avoid the unexpected water quality sampling value changes for causing to be temporarily, therefore, take the sampled value that continous way is detected beyond setting
Definite value, just carries out the monitoring of continuation.
From the above, when the sample values of double collection exceed setting value (i.e. the normal range (NR) of water quality data)
Afterwards, continuous sampling pattern is automatically switched to, the corresponding water quality parameter of anomaly parameter gathers sensing unit 117 by main control unit
Data are stored in data storage element (such as EEPROM) by the 151 control continued powers of power subsystem 159, while the local alarm of triggering
Device and pass through data transmission unit 157 carry out remote alarms information push.After attendant reaches the spot, insertion can be passed through
Formula Touch Screen 134 checks specific warning message.When acquisition parameter sampled value is recovered to setting value (the i.e. normal model of water quality data
Enclose) within, local warning device is closed, while sending alarm release information by data transmission unit 157, is automatically switched to just
Normal patrol mode.
In addition, in present embodiment, multichannel water quality monitoring system 1 further includes cleaning module 18, cleaning module 18 is included
Driver element 181 and cleaning unit 183, driver element 181 are located on water sample flowing lumen body 113, and cleaning unit 183 is located at water sample
