Description
Technical field
This invention relates to multi-sensor field, particularly relates to ocean water quality field of sensor devices.
Background technology
Marine pollution is an international problem.Protecting the marine environment, preventing marine pollution is the common prescription of various countries.The feature of marine pollution is
Polluter is wide, and the kind of poisonous and harmful substance is many, and range of scatter is big, endangers far-reaching, controls complexity, and difficulty of governance is big.Therefore, marine pollution ratio
Play other land environmental pollution and want serious and complicated.In order to preferably protect and utilize ocean, collection and analysis to marine environment data are in weight
Weight.Ocean monitoring technologytechnologies quickly grows at present, and monitoring technology is towards integrated, real time implementation and intelligent development.
But at present under marine environment, the application of integrated sensing there is also two bottleneck problems: 1. cannot long time continuous working because most of sensor,
Such as pH sensor, it is easy to adhered to by the pollutant in sea water and make it lose efficacy；2. to carry battery electric quantity limited for sensor, integrated sensor
Running hours length be restricted.
Summary of the invention
It is an object of the invention to provide a kind of ocean water quality sensor device that can reduce sensor energy consumption and extend the sensor effective time.This
The technical scheme of invention is as follows:
A kind of ocean water quality sensor device certainly waking up mechanism based on intervalometer up, including pH sensor module, turbidity transducer module, temperature
Sensor assembly, main control chip, from wake-up circuit and external timer, wherein,
Turbidity transducer utilizes the turbidity transducer immersing seawater surface to gather the turbidity information of sea water；Temperature sensor module utilizes temperature sensor to adopt
The temperature information of collection seawater surface；PH sensor module gathers seawater pH value, and the data of each sensor acquisition are admitted to main control chip；
Described pH sensor module includes PH meter main body (1) and coupled ball electrode bubble (3), it is characterised in that main at PH meter

Detailed description of the invention
The present embodiment is the integrated sensor device for ocean water quality long term monitoring.
It is illustrated in figure 1 based on intervalometer from the schematic block circuit diagram of the ocean water quality sensor device waking up mechanism up.Including pH sensor module,
Turbidity transducer module, temperature sensor module, signal amplification circuit, A/D convertor circuit, memory element, main control chip, mu balanced circuit, from
Wake-up circuit, external timer and power supply composition.
Sensor node is gathered water quality information and is outwards transmitted by wireless signal；Turbidity data is passed back by turbidity transducer module by turbidity transducer
Control mainboard；Ambient temperature data is passed back control mainboard by temperature sensor by temperature sensor module；Signal amplification circuit can gather sensor
Small-signal that module produces also is amplified and is filtered, and output converts analog signals into digital signal to A/D convertor circuit；Main control chip receives
After the digital signal of A/D convertor circuit transmission, store data in memory element；Power supply provides electric energy by mu balanced circuit for main control chip.
It is illustrated in figure 2 from the workflow diagram waking up sensor up.Storing the reference time intervals waken up up in described external timer is 1 hour,
Sensor device gathers a seawater quality information the most per hour.After arriving reference time intervals, intervalometer overflows, and it is fixed to perceive from wake-up circuit
Time device overflow after just export a rising edge level to main control chip, main control chip starts to control sensing system and gathers water quality parameter.Data acquisition is complete
Cheng Hou, after intervalometer zero, chip is again introduced into resting state, waits and waking up up, and so forth next time.
Be illustrated in figure 3 pH sensor, i.e. pH meter, structural representation, pH meter includes pH meter main body 1, ultrasound unit 2, pH meter
Ball electrode bubble 3 and Ultrasonic Radiation flat board 4.PH meter main body 1 is internal is the 3mol/L kcl buffer solution containing saturated AgCl, and pH value is 7.Just
In the case of Chang, it is internal, within pH meter main body 1 that the H ion in solution to be measured can enter into pH meter main body 1 by pH meter ball electrode bubble 3
Electrode can detect potential change, thus draws the pH value of solution to be measured.When pH meter ball electrode steeps 3 surfaces by contaminated aqueous solution to be measured, H from
Subchannel can be blocked, and pH meter just can't detect potential change, i.e. cannot correctly detect pH value.
The present invention is fixed with ultrasound unit 2 in pH meter main body 1 near the position of ball electrode bubble 3.Ultrasound unit 2 includes supersonic generator
And ultrasonic transducer, the active antenna launching ultrasound wave that the present invention uses is plate aerial, is made up of two relative flat boards, referred to as radiation
Flat board 4.Supersonic generator includes agitator, power supply, amplifier and adapter.Supersonic generator is used for producing supersonic frequency electric energy, ultrasonic
In wave producer, agitator produces the signal of certain frequency, and amplifier is amplified to the output of certain power, carries out impedance matching also by adapter
Exported by power amplifier.
Seeing Fig. 4, ultrasound unit 2 produces ultrasonic signal, and by the transmitting of Ultrasonic Radiation flat board 4, pH meter ball electrode is steeped 3 tables
Solution near face shakes so that it is ball steeps the pollutant on 3 surfaces and departs from, and discharges H ion channel, makes pH meter recover sensitive.
