Description of the Invention: [Technical Field] The present invention relates to a GPS sea surface fluctuation observation method, and more particularly to a method for detecting the velocity of water particles on the sea and then obtaining water surface fluctuation data. [Prior Art] #, The observation and acquisition of the sea wave information of the sea area, the observation of the Xiangbu floating body with observation devices. The observation device uses the conventional accelerometer to observe the wave φ 'good' system according to the wave analysis theory, and analyzes the acceleration, east-west and north-south inclination when the sequence is free of the ship (four) material. According to the practice of scales, the floating body problem changes with the wave surface movement. However, the floating body made by the technology must be limited to a dish-shaped floating body in order to make the observations _ optimal, and other types of floating bodies cannot be used. Furthermore, conventional observation techniques use accelerometers to observe waves. However, during the observation, the accelerometer generates noise, so that the sequence of the acceleration time outputted by the accelerometer is calculated according to the wave knife analysis theory, and then converted into the water level spectrum by the frequency quadratic reciprocal, thereby obtaining Wave height, cycle data. At the same time, the acceleration spectrum noise is also subjected to the frequency quadratic reciprocal conversion, so that the frequency of the low frequency noise is amplified larger than the frequency, and the wrong water level spectrum is obtained. Conventional techniques also use RTK_GPS to measure sea level changes. When using RTK_GPS, 'use more than two GPS receivers. And set one of them to the known location=fixed point is called GPS reference station. The GPS reference station calculates the atmospheric county based on the received observation data ( The lion layer and tropospheric delay) and the error caused by the financial error are transmitted to the other =PS receivers through the terrestrial radio or the electric m, and the relative vector of the receiver and the base station is calculated instantaneously. Position of accuracy #^ However, RTK GPS has (4) its limit, that is, when the base station and the receiving g increase, the domain error is changed, so that the receiver can only reach about four kilometers from the wire queuing station to achieve the public classification accuracy. . Therefore, the RTK GPS wave measurement system can only be applied to coastal waters, and this technology can be applied to deep sea areas, and the measurement accuracy will be greatly reduced. In view of this, our inventors have solved the problems caused by the conventional observation techniques and have not been invented after continuous design and improvement. SUMMARY OF THE INVENTION Shame is a GPS sea surface fluctuation observation method provided by the present invention, and the purpose thereof is to make the observation device provided on the floating body not subject to the limitation of the GPS reference station and the interference of the low frequency signal, and fluctuate in any sea area (4) And as a secret floating body can move with the wave water particles, and does not limit the shape of the floating body, you can get accurate information on sea surface changes. To achieve the above object of the present invention, the present invention is a method for Gps sea surface fluctuation, and the method includes: the GPS module detects the amount of change in the wave motion of the χ axial direction, the γ axis, and the 2 axial direction, And converting the output wave motion speed time sequence, the analysis processing mode _ the removal of the secret time sequence _ containing the low frequency miscellaneous, retaining the sequence of the true wave/good motion velocity, and applying the Fourier transform analysis method to the motion capture time sequence, And with the wave theory, the wave data such as the diurnal spectrum, the one-dimensional water level spectrum, the indicative wave surface, the average period and the direction spectrum are obtained. 1356897 According to the above concept, the GPS sea surface fluctuation observation method further comprises: a speed sound spectrum, a one-dimensional water gift, a display wave height, an average position and a direction wave fresh wave material: the analysis processing module is coded as a data string, And storing the data string in the storage module 1 according to the above concept, wherein the storage group is a hard disk drive or a card reader that uses her memory card and a Compact Flash memory card as a recording medium. According to the above concept, the GPS sea surface fluctuation observation method further comprises: the analysis processing module outputs the data string to the transmission module, and the transmission unit transmits the data string to the remote base station in a non-transmission manner. . According to the above concept, it is a scale motor, a GSM data machine, a GPRS data machine or a satellite transmission device. [Embodiment] The technical means of the present invention will be described in detail below with reference to the drawings, and the present invention will be further understood and recognized. First, please refer to the figure-picture, which is the preferred implementation of the Gps sea surface fluctuation observation method of the present invention. In the implementation of the money, the method must be implemented by the observation device 00 set in the floating body. The observation device (10) includes a milk module (Η), an analysis processing module 2G, a library module 3G, a transmission module 4G, and a power module 50. Among them: The milk mold has a global positioning system (Giobai Positioning SySteffl, GPS). The GPS module 10 and the analysis portion are configured to change the water particle velocity of the X-axis, the γ-axis, and the Z-axis of the floating body when the floating body is finely floating in a predetermined observation sea area. And simultaneously outputting the two-axis motion speed phase to the analysis service group 2G^ The X-axis is preset to the east-west direction in this example, that is, the GPS module 10 detects the east-west water particle velocity. Variety. In this example, the Y-axis is preset to be north-south, that is, the GPS module 1G detects the north-south water particle velocity dependence. The Z-axis is in the direction perpendicular to the sea level, that is, the GPS module detects the vertical velocity change of the water level. The analysis processing module 2 is electrically connected to the GPS module 1 , the storage module 3 , and the transmission module 40 . The analysis processing module 2 uses the analysis processing software to calculate the motion velocity time sequence transmitted by the GPS module 1 as an input value, and after processing, the water particles are obtained in the X axis, the γ axis, and the Z axis. Wave data such as velocity spectrum, water level spectrum, indicative wave height, average period and direction spectrum are compiled, and the wave data is compiled into a data string and output to the transmission module 4G and the storage module 30 at the same time. The storage module 30 receives the data string outputted by the analysis processing module 2, and stores the data string. The storage module 30 is a hard disk drive or a card reader using a flash memory card or a Compact Flash memory card as a recording medium. The transmission module 4 receives the data string output by the analysis processing module 2〇. The transmission module 40 is transmitted to the remote base station by wireless transmission. The transmission module is a radio, a GSM modem, a GPRS modem or a satellite transmission. The power module 40 is electrically connected to the GPS module 10, the analysis processing module 2, the storage module 30, and the transmission module 40, and is configured to provide the modules 1〇' 2〇, 3〇 The power supply. 8 1356897 As shown in the second figure, 'When the observation slot 100 is set in the floating body and placed in the predetermined observation sea, the floating body (four) surface floats and moves with the wave water particles' and the analysis processing The module 2 starts the Gps module 10 and the transmission charm 40 at a preset time period, so that the GPS module 1 〇 instantaneously produces water particles in the sea area in the X axis, the Y axis, and the 2 axis. The speed changes, and at the same time, the analysis processing module 2〇 is analyzed and operated corresponding to the output of the three-axis motion speed. As shown in the third figure, the analysis and calculation steps of the analysis processing module 20 are as follows: Step-S Huan the division of the fishing 2G to three (four) filament movement speed B temple sequence. The GPS module 1 detects and acquires the physical quantity of the water particle velocity in the X-axis, the γ-axis, and the z-axis and transmits the sequence of the motion capture to the analysis processing module. The analysis process 敝20 looks like the fresh speed physical quantity as the input value of the arithmetic processing. Step 2 S2GG: Does the analysis process touch 2Q in the pair of lying wires? Movement speed Before the sequence is calculated, it will first determine whether there is a GPS signal offset (10) (4)
Loss)。所謂GPS訊號偏移（GPS Signal Loss)，指當GPS衛星發 生偏移或訊號無法接收時，GPS模組1G所輸出之水粒子運動速度 時序列則會出現-整段往上或往下偏移的現象（Gps抑㈣Loss). The so-called GPS signal loss (GPS Signal Loss) means that when the GPS satellite is offset or the signal cannot be received, the sequence of water particle motion speed output by the GPS module 1G will appear - the entire segment is shifted upwards or downwards.

When the analysis processing module 20 detects the motion speed by using the moving average method to detect the motion speed, the sequence has a GPS number offset, and then enters the program of the age Gps signal offset. In contrast, the analysis processing module 20 performs the analysis of the wave information for the motion time series. Step 3: S300: When the analysis processing module 20 determines the motion speed, the sequence has 9 1356897 GPS signal offset, then the analysis processing module 2 () further reserves the 峨, which is true to the wave speed, that is, Destroy the wave information - count. ··· Turn to the fourth discussion: In this step, the analysis processing module 20 obtains the velocity spectrum for the three-axis operation = speed timing smoothing process. _ The change of the water level in the wave has a stationary, erg () dic) and a high __ _ _ (four) said ‘the time is difficult to grow with the lining of Lang’s.
