[Abstract]:With the rapid economic development of all countries in the world, the global demand for energy is increasing. The excessive consumption of natural gas, oil and coal, such as natural gas, oil and coal, and more and more serious greenhouse effect and continuous fog haze force people to urgently look for the development and utilization of cheap, clean and pollution-free. The surface area of the new renewable energy. The surface area of the earth is 510 million km2, the ocean is 361 million 100 thousand Km2, accounting for more than 2/3 of the earth surface area, the ocean area and the land area are close to the proportion of 7:3. The sea not only provides water for human beings, shipping and rich mineral resources, but also contains huge energy, in which ocean waves can be a new type of energy. Pollution free, abundant storage and other significant advantages and huge development and utilization value have attracted worldwide attention.
Through the research of remote monitoring technology, communication technology, computer technology and data processing, it combines the advantages of the real-time, maintainability, automatic data acquisition and processing of the computer monitoring system and the convenience of human-computer interaction. At the same time, it takes into account that the computer monitoring system should be developed according to the particularity of the monitoring site. In this paper, a remote monitoring system for ocean wave energy generation is developed on the basis of the Windows7 operating system and using the GPRS wireless communication technology in the VB6.0 (VisualBasic6.0) development environment.

It ensures the uninterrupted communication and the security and reliability in the process of data exchange.
(2) the system's energy management hardware integration scheme and wireless data transmission terminal are designed, and the energy processing flow is developed. The generator output three-phase alternating current via rectifying and filtering processing is more pure DC, and then the lithium battery is charged through the charge controller before charging the 13.8V-60V range. The battery can be charged by electricity. The 24V DC provided by the lithium battery can be used directly for the DC load buoy. It can also be converted into AC load with rated frequency and amplitude by the inverter. The system uses the GPRS-DTU wireless transmission equipment connected to the intelligent DC power meter through 485 buses. Data transmission of field equipment.
(3) the data transmission of the system is based on the communication of the Modbus bus protocol. The communication protocol and the RTU transmission mode are studied. Through this protocol, the communication is completed between the wireless terminal and the intelligent instrument, and the current data from the field generator output, the voltage data and the power data are read smoothly.
(4) focus on the design of the system monitoring center software, including: (1) the characteristics and advantages of the VB development environment and the communication control Winsock provided in the VB to complete the communication between the two and more computers in the network; (2) the design of the system landing interface and the monitoring master interface, including the native IP address and end on the main interface. The setting and display of the mouth, the historical data curve and the real-time data curve display; how to establish the Access database, how to add the ADO control to the VB operation interface to access the data in the database and to store the data information of the collected field power generation equipment by using the Access database.
The ocean wave energy monitoring system based on GPRS wireless network has completed the receiving of the main parameters (voltage, current, power) of the generator in the field, and transmitted the received data to the school information center through wireless communication, and the generator is in the state of power under the condition of the marine environment. Through the analysis of historical data and real-time data, the working state of the generator is judged, and the optimal load that needs to be invested is determined. The development of the system breaks through the limit of distance, realizes the acquisition and operation of the information of the terminal of the remote generation equipment, and makes the management personnel at the same time. This system has the advantages of low cost, simple structure, easy operation and so on. It is proved that the system has good stability and practicability by calculating and analyzing a large amount of data collected from the field.
