The temperature of the ocean is a very important physical quantity characterizing the ocean, and in particular, the temperature field vertically distributed along the ocean depth determines the number of horizontal layers of the ocean and the thickness of each layer, and it is the vertical layers of the ocean that are due to the longitudinal vertical layers of the ocean, which have different physical properties, such as different propagation properties of sound therein due to the density of the ocean water between different temperature layers, etc.
The typical method for monitoring the ocean temperature and depth information is to detect the ocean temperature and depth information through a sensor, the sensor detection can realize long-term real-time measurement, and has the advantages of high precision, sensitive response and good stability, and the seawater temperature on the ocean vertical structure can be measured in real time through a plurality of sensors connected in series, so that the technology is relatively mature, the real-time observation of the seawater temperature change can be realized by combining with a computer and a communication technology, and the observation data can be recorded in real time.
The fiber bragg grating sensor is a novel sensor, an optical fiber is adopted as a medium for signal transmission and measurement, an optical signal is not affected by electromagnetic interference and is easy to measure in complex occasions, long-distance transmission of the signal is very convenient to achieve due to low transmission loss of the optical fiber, the problems that the conventional resistance, piezoelectricity and vibrating wire sensor is single in measured physical quantity, short in signal transmission distance, easy to interfere in signal relay transmission, complicated in engineering construction wiring and the like are completely broken through, and the fiber bragg grating sensor is an important sensor for detecting ocean temperature and depth information.
However, the ocean temperature detection is carried out by an optical fiber sensing temperature measurement method, the acquired signals are required to be demodulated by corresponding optical fiber grating demodulation equipment, and the process is generally realized by combining a high-performance computer, so that the ocean temperature and depth monitoring system is large in size and high in cost. The monitoring system is also limited by the fact that the computer is provided with corresponding software to acquire observation data, and can only perform temperature deep observation at the computer end, so that seawater temperature data cannot be acquired anytime and anywhere.
In order to solve the above-mentioned problems, the present application proposes a marine Wen Shenyuan-process monitoring system based on a fiber bragg grating demodulator, as shown in fig. 1, the system includes a light source 1, a demodulation module 2, an optical switch 3, a processor 4, a fiber optic adapter 5 and at least one fiber bragg grating sensor, wherein the fiber bragg grating sensor is an external device, and is not shown in fig. 1. It should be understood that in order to achieve detection of ocean temperature and depth, at least one fiber grating sensor should be provided in the different temperature layers to obtain the depth change of ocean temperature.
The light source 1 is connected with the optical fiber adapter 5 through optical fibers, the optical fiber adapter 5 is connected with the input end and the output end of the optical fiber grating sensor through optical fibers, and the input end of the optical fiber grating sensor receives signal light sent by the light source 1 through the optical fiber adapter 5, so that the light source 1 can control the corresponding optical fiber grating sensor to monitor the ocean temperature and the ocean depth by sending out corresponding detection signal light.
The optical fiber adapter 5 can be regarded as an optical transmission device composed of a plurality of optical interfaces, and the optical fiber adapter can connect the light source 1 and the demodulation module 2 to a plurality of fiber grating sensors. The light source 1 may be an SLED broadband light source, which has a wide operating band and can emit signal light with a plurality of different wavelengths, so that the fiber bragg grating sensor has a wide detection range.
It should be understood that the number of optical interfaces of the optical fiber adapter 5 is 2 times the number of optical paths extending from the light source 1, for example, when the number of optical paths extending from the light source 1 is n, the number of optical interfaces of the optical fiber adapter 5 is 2n, where n may be any one of 2, 4, 6, 8, etc., and the specific value of n is not limited in this application. The number of the optical fibers connected to the optical fiber adapter 5 by the light source 1 is n, and in the same way, in order to control the on-off of the optical paths of the optical fibers, the number of the input interfaces on the optical switch 3 is the same as the number of the optical fibers, and the number of the input interfaces can also be n.
The optical switch 3 may be a magneto-optical switch, which can control on/off of an optical path under the action of magnetic force, and in this embodiment, has n input ports and n output ports, so that n optical fibers can be connected to the optical fiber adapter 5. It should be understood that, because there may be a part of the optical fiber adapter 5 with an unconnected optical fiber grating sensor, the optical switch 3 can disconnect the optical fiber corresponding to the optical interface of the unconnected sensor, so that the light source 1 is prevented from sending signal light to the optical interface of the unconnected sensor, and waste is reduced.
The demodulation module 2 is a module for demodulating a signal output by the fiber grating sensor in the system, and the demodulation module 2 is connected with an output end of the fiber grating sensor through the fiber adapter 5 to acquire and demodulate spectrum information output by the fiber grating sensor, so that the spectrum information can be further processed to acquire temperature and depth data corresponding to the fiber grating sensor. The demodulation module 2 is thus communicatively coupled to the processor 4 to transmit the spectral information to the processor 4, enabling the processor 4 to perform an acquisition analysis of the spectral information to obtain ocean temperature depth monitoring data.
In some embodiments of the present application, the processor 4 may be a miniaturized, low-cost structure capable of carrying a certain software to perform an operation, and by way of example, the processor 4 may be any of a CPU, a raspberry pi (a kind of embedded Linux board card), a singlechip, and other miniaturized computing structures, which are not limited to the specific type and model of the processor 4, and in the embodiments of the present application, the above functions are implemented by using the raspberry pi as the processor 4. After the processor 4 analyzes the ocean temperature and depth monitoring data, the obtained monitoring data can be transmitted to the outside through the USB port connection.
Furthermore, in order to realize remote data acquisition, in the offshore area, a USB interface flow card or a transceiver antenna can be arranged in the processor 4 and an independent IP can be configured, and the two-way real-time communication between the processor 4 and the webpage end is performed based on a WebSocket communication protocol, so that the efficient data transmission is realized, and the change of the seawater temperature observation data can be acquired anytime and anywhere by opening a corresponding webpage on a mobile terminal or other equipment with a networking function. For the open sea area where the communication can not be realized by using the flow card, the data acquired and analyzed is transmitted back to the land through the satellite by arranging the satellite communication module in the processor 4, so that the data communication with the mobile terminal is realized.
In some embodiments of the present application, the cloud server may be further configured in a manner of collecting and analyzing the ocean temperature and depth monitoring data by the processor 4, and then, through communication connection with the processor 4 and the cloud server, the processing analysis result of the spectrum information by the processor 4 is sent to the cloud server, and then, through the mobile terminal or other devices capable of being connected to the cloud server, the data obtained by the processing analysis of the processor 4 is remotely obtained by the cloud server, so as to improve flexibility of data query.
In some embodiments, the marine Wen Shenyuan system may further include a memory module communicatively coupled to the processor 4 to receive and store the processing results of the processor 4 on the spectral information. Illustratively, the memory module may also be disposed within the processor 4, such as by providing a memory slot on the processor 4 to provide the memory module in the processor 4. After the processor 4 obtains the ocean temperature and depth data through information processing, the ocean temperature and depth data can be stored in the storage module, so that the ocean temperature and depth data can be inquired and called through the Ethernet connection and other modes.
Through the embodiment, the processor 4 is arranged in the demodulator, so that signals acquired by the fiber bragg grating sensor are analyzed and processed in the demodulator to replace computing equipment connected with the demodulator, the integration level of the marine Wen Shenyuan-range detection system is improved, and the volume and cost of monitoring equipment are reduced.

In some embodiments, as shown in fig. 1, the light source 1 includes a light source switch 11, where the light source switch 11 is electrically connected to the light source 1, and the light source switch 11 is disposed on the front panel to control the light source 1 to be turned on or off, and the light source switch 11 can control the light source 1 to be turned on or off by controlling the on/off of a circuit of the light source 1, so that the light source 1 can be independently controlled, and thus the light source 1 is turned on or off under the condition of power on, so as to start or terminate the transmission of signal light.
For example, in the process of actually using the system, after the power supply port 9 is connected with a power supply, the power switch 10 arranged on the front panel 120 is turned on to control the system to start the processor 4 when the power is on, and software in the processor 4 for processing data can be set to be started up and self-started, and after the processor 4 is successfully started up, the software runs automatically. The channel of each fiber adapter 5 on the front panel 120 can be connected with a certain number of fiber grating sensors in series according to the measurement requirement and placed at different depths of sea water, and real-time temperature measurement is carried out on the sea water profile so as to obtain the depth temperature information of the sea. The light source 1 emits light with a certain wavelength range, the light is transmitted (or reflected) by the sensor and then is transmitted to the demodulation module 2, the demodulation module 2 collects corresponding spectrum information in sensor return signal light by adopting a high-performance linear array image sensor and then transmits the corresponding spectrum information to the data collection board 6, the data collection board 6 transmits the spectrum information to the processor 4 through wireless communication (Ethernet communication, bluetooth communication and the like), and collection control is realized by software in the processor 4. The change of the seawater temperature can cause the movement of the wave crest or wave trough position in the spectrum, and the wave length corresponding to the wave crest or wave trough is calculated through a peak/trough searching algorithm, so that the current seawater temperature and the change thereof are calculated according to the functional relation between the wave crest or wave trough and the temperature. The mobile terminal is connected to the cloud server through the independent IP address of the processor 4, so that the spectrum information and the corresponding temperature change condition of the corresponding channel in the system can be checked, and meanwhile, the storage of wavelength and temperature data can be realized.
