Marine water quality sensor device based on timer self awakening mechanism

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...

Problems solved by technology

[0003] However, there are still two bottlenecks in the application of integrated sensing in the marine environment: 1. It cannot work continuously for a long time, because most sensors, such as pH sensors, are easily attached by pollutants in seawater and make them invalid; 2. .The battery power of the sensor is limited, and the continuous working time of the integrated sensor is limited
