Embodiment Construction

[0016] The specific implementation of the present invention will be described in detail below in conjunction with the technical scheme and accompanying drawings.

[0017] The structural block diagram of the deep-sea self-capacitance sensor based on multivariable of the present invention is as follows figure 1 shown. The sensing unit selects the sensor chip based on MEMS technology to sense the signal, and the data acquisition and storage unit is responsible for storing the acceleration, inclination, temperature and humidity data sensed by the MEMS chip in the Flash memory. When the data needs to be exported, the data can be exported through the communication interface to on the computer. The power supply module is composed of an energy supply system, a power supply voltage stabilization chip and a battery. The energy supply system is composed of an electromagnetic linear generator, a super capacitor and a voltage multiplication circuit; the battery is a lithium battery. The ...

Abstract

The invention relates to a deep sea self-contained type sensor based on multiple variables and an energy supply method thereof. The deep sea self-contained type sensor locally comprises a sensing unit, a data acquisition storage unit and a power supply module, wherein the sensing unit comprises an acceleration sensor, an inclined angle sensor and a temperature and humidity sensor; the data acquisition storage unit comprises an MCU (Micro Controller Unit), a storage, a clock circuit and a communication interface; the communication interface comprises a USB (Universal Serial Bus), a serial port and a wireless interface; and data is transferred to a computer through the communication interface, the change in acceleration of vibration and inclined angle of an ocean platform structure can be monitored and the change in temperature and humidity of marine environment can also be monitored. The deep sea self-contained type sensor based on multiple variables overcomes the defect of a traditional monitoring method for only monitoring a variable, can simultaneously monitor multiple variables and has the characteristics of high test precision, excellent stability, low power consumption, small size, and the like. Meanwhile, according to the provided energy supply method, the vibration energy of the ocean platform is converted into available electric energy so as to supply power to the disclosed sensor, so that energy is saved, environment is protected and working time of the sensor is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of offshore platform structure monitoring, and relates to a multi-variable deep-sea self-capacity sensor and its energy supply method, in particular to a data acquisition of acceleration, structure inclination angle and seawater temperature and humidity using sensing technology , and then analyze the collected data to achieve the purpose of monitoring the marine environment under the ocean platform and the structure of the ocean platform itself. Background technique [0002] The offshore platform structure is the most important infrastructure for the development of offshore oil and gas resources, and it is the base for offshore production operations and living. At present, there are more than 6,500 offshore platform structures operating in the waters of 53 countries around the world, creating huge wealth for the world. Generally, the service period of offshore platforms is 20 years. However, due to the high...
