Embodiment eight:
The present embodiment is a kind of Legionella method for early warning that uses the described system of above-described embodiment, and the step of described method is as follows:
Control and instruction that signal processing apparatus sends according to warning center or according to predetermined time interval intercept the physical and chemical parameter of monitored water source water temperature that each sensor of physics and chemistry detection subsystem obtains, pH value, conductivity, chlorine residue, turbidity, flow, flowing time and analyze, determine whether as the Legionella Reproduction Conditions.As previously mentioned, the physical parameter of the Reproduction Conditions of Legionella to a certain extent, easy detecting very.But, be not to have possessed just certain generation Legionella of these conditions, or there is no conversely speaking, these conditions, just can produce Legionella scarcely.Modern research shows, above-mentioned these conditions are only the top conditions of Legionella breeding.Whether there is Legionella also will could determine through biochemistry detection.The meaning that physics and chemistry detects is, these physical and chemical parameters can be surveyed continuously, and easy to detect, under the modern digital condition, very easily detect and transmit online, are the technology of high mature.And biochemistry detection is relatively difficult, testing cost is high, can't realize continuous detection.Only have the combination of two kinds of technology to be only best selection.
Control and signal processing apparatus is treated to digital signal by physical and chemical parameter and analysis result and transfers to warning center by signal receiving/transmission device and public communication network.Physical and chemical parameter can be surveyed continuously, therefore, can detect at any time, and record, to warning center transmission physicochemical data, be total to the warning center analysis at any time at any time.
Control and signal processing apparatus send the instruction that starts biochemistry detection to the biochemistry detection system according to the detection event.The described detection event of this step is several situations that control and signal processing apparatus run into.These several situations comprise: physics and chemistry detects condition, the warning center of finding the Legionella breeding and sends the instruction that starts biochemistry detection, the time interval of predesignating.
Physics and chemistry detects the condition of having found the Legionella breeding to be possessed, and this just may produce Legionella, therefore needs in this case to start biochemistry detection, because biochemistry detection could finally determine whether the Legionella breeding or exist.
Also having a kind of situation is that biochemistry detection is carried out in the startup of warning center direct instruction biochemistry detection subsystem.Because under certain conditions, for example, artificial discovery the Legionella situation that may occur, or other reasons need to carry out biochemistry detection immediately, the biochemistry detection subsystem start detection that warning center can certain check point of immediate instruction.
Predetermined time, interval was the modal startup reason of automated detection system.Common automatic checkout system is all to detect by certain time interval.Generally, the time interval is fixed.For example each hour, every 12 hours, weekly etc.But some special place of the detection of Legionella.Because biochemistry detection is costly, in the situation that do not have physics and chemistry to detect, regular biochemistry detection, the high cost of carrying out.Therefore, someone has proposed a kind of step detection model.
At first the batch (-type) detection model assesses the safe class at monitored water source.The method of assessment is to analyze the data in this system past, according to factors such as artificial safeguard procedures such as systematic protection measure, the dispensing of the probability of occurrence of Legionella, equipment are sterilizing, it is divided into: idealized system, security system, time-dependent system, four grades of high-risk system.Idealized system carried out one time biochemistry detection in every six months, and the security system every three months carries out biochemistry detection one time, time-dependent system every month or carry out weekly biochemistry detection one time, carried out one time high-risk system every day or U.S. 12 hours biochemistry detection.More than just intermittently detection model for example, the actual time interval and condition all can change.
The biochemistry detection subsystem according to control and the instruction of signal processing apparatus start detection from monitored water source, randomly drawing on-the-spot water sample.
On-the-spot water sample is treated to sample to be tested through sample preparation facilities to be detected.In this step, typically use suspending liquid by the bacterial suspension in on-the-spot water sample, in order to detect.
When carrying out above-mentioned two steps, detection subsystem is from extracting a not collaurum in Kaifeng the collaurum memory storage, and the encapsulation device for opening is opened the encapsulation of collaurum, exposes colloidal gold test strip.Collaurum normally seals, otherwise can't retain for a long time, opens encapsulation and just can test.
Sample to be detected is added on the test-strips of collaurum.Sample to be tested can only have 0.1 milliliter to get final product, therefore must the strict amount of controlling sample to be tested.
The testing result reading device reads the striped demonstration of colloidal gold test strip, and is converted into striped demonstration digital signal, transfers to and controls and signal processing apparatus.This step, with camera or contact-type image sensor, is converted into data image signal by the demonstration of the striped of collaurum, and this data image signal is convenient to carry out graphical analysis, also is convenient to the transmission of modern any communication network.Due to the power of digital image analysis software, any variation that striped shows, after being converted to digital picture, is easy to analyze and identification more.
Control and signal processing apparatus show that by striped digital signal transfers to warning center by public communication network.Due to the prosperity of modern means of communication, any digital signal all can be transmitted very easily, and this technology is very ripe.
Control and signal processing apparatus when operating, the biochemistry detection subsystem used collaurum of dishing out, bactericidal unit carries out disinfection to the biochemistry detection subsystem.After each the detection, all must carry out sterilization, accurate with what keep detecting.Sterilization, can be that whole detection subsystem is carried out disinfection, and also a desinfection chamber can be set specially, and desinfection chamber is carried out disinfection.
The striped that warning center is received by analysis shows digital signal, stores on the one hand striped and shows digital signal, takes simultaneously to ignore, further analyze, send early warning, several different counter-measures.This step can require to select according to different monitorings.For example, be only that early warning just can directly be sent warning, if also need further confirmation, need warning center the detection subsystem of finding Legionella to be sent to the instruction that starts the biochemistry detection subsystem, biochemistry detection tries again.
Embodiment nine:
The present embodiment is the improvement of embodiment eight, is that embodiment eight is about detecting the refinement of event.The described control of the present embodiment and signal processing apparatus send in the step of the instruction that starts biochemistry detection to the biochemistry detection system according to the detection event, and described detection event is: draw it is the condition of Legionella breeding according to the analysis to physical and chemical parameter.
The analysis of physical and chemical parameter can only illustrate the condition that has possessed the Legionella breeding, at first can not illustrate and Legionella occur, can not illustrate and there is no external Legionella invasion.If, so the physical and chemical parameter analysis has possessed the condition of Legionella breeding, will carry out biochemical test, produce to have determined whether the Legionella breeding.
Embodiment ten:
The present embodiment is the improvement of embodiment eight, is that embodiment eight is about detecting the refinement of event.The described control of the present embodiment and signal processing apparatus send in the step of the instruction that starts biochemistry detection to the biochemistry detection system according to the detection event, and described detection event is: a kind of in the biochemistry detection instruction that warning center sends or predetermined time interval.
In strict Legionella examination criteria, do not allow the existence of any Legionella, therefore, it is far from being enough only relying on physics and chemistry to detect, and must carry out biochemistry detection.On time to carry out biochemistry detection the safest.
Finally it should be noted that, below only unrestricted in order to technical scheme of the present invention to be described, although with reference to the preferred arrangement scheme, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention (such as the various forms in each device in the connected mode, detection subsystem between each device in detection subsystem etc.), and not break away from the spirit and scope of technical solution of the present invention.
