Embodiment Construction

[0015] This embodiment is an integrated sensor device for long-term monitoring of ocean water quality.

[0016] like figure 1 Shown is the circuit principle block diagram of the marine water quality sensor device based on the timer self-wake-up mechanism. It consists of pH sensor module, turbidity sensor module, temperature sensor module, signal amplification circuit, AD conversion circuit, storage unit, main control chip, voltage regulator circuit, self-wake-up circuit, external timer and power supply.

[0017] The sensor node collects water quality information and transmits it through wireless signals; the turbidity sensor module transmits the turbidity data back to the control board through the turbidity sensor; the temperature sensor module transmits the ambient temperature data back to the control board through the temperature sensor; the signal amplification circuit can collect The weak signal generated by the sensor module is amplified and filtered, and output to the A...

Abstract

The invention relates to a marine water quality sensor device based on a timer self awakening mechanism, which comprises a pH value sensor module, a turbidity sensor module, a temperature sensor module, a main control chip, a self awakening circuit and an external timer, wherein the pH value sensor module comprises a PH meter main body (1) and an electrode bulb (3) connected with the PH meter main body, an ultrasonic wave radiation flat plate (4) and an ultrasonic wave module (2) are arranged at one end, connected with the electrode bulb (3), of the PH meter main body (1), and the ultrasonic wave radiation flat plate (4) is located around the electrode bulb for enabling ultrasonic waves generated by the ultrasonic wave module (2) to form oscillation near the surface of the electrode bulb (3). After a reference time interval arrives, the external timer flows over; after the self awakening circuit senses the overflow of the external timer, awakening signals for the marine water quality information are acquired and transmitted to the main control chip; and thus, the effective working time duration of an integrated sensor can be prolonged.

Description

technical field [0001] The invention relates to the field of marine water quality monitoring, in particular to the field of marine water quality sensor devices. Background technique [0002] Marine pollution is an international problem. Protecting the marine environment and preventing marine pollution are the common requirements of all countries. Marine pollution is characterized by a wide range of pollution sources, many types of toxic and harmful substances, a wide range of diffusion, far-reaching harm, complicated control, and difficult governance. Therefore, marine pollution is more serious and complicated than other environmental pollution on land. In order to better protect and utilize the ocean, the collection and analysis of marine environmental data is a top priority. At present, marine environmental monitoring technology is developing rapidly, and monitoring technology is constantly developing towards integration, real-time and intelligence. [0003] However, t...
