Background
Along with the diversity and the quantity increase of photovoltaic platform district access device type, wherein involve the terminal and the interaction of multiple electric energy device equipment, especially involve and add various 'terminal + table' for realizing different demands, the phenomenon that new and old product coexisted in the standard change transition in addition, and then lead to equipment in the whole photovoltaic platform district to be miscellaneous, and the field installation wiring is disorderly fallen with the line. Meanwhile, in the process of continuously advancing to the intelligent direction of information acquisition of the photovoltaic platform area in China, various novel intelligent terminals and intelligent electric meters are continuously hung and used on the site step by step, so that the running condition of the current photovoltaic platform area in a long period of time in the future is still very severe. The invention provides a photovoltaic intelligent metering device and a method based on self-adaptive communication aiming at the problem caused by the fact that equipment redundancy and communication modes are not uniform in the current photovoltaic platform area application scene.
At present, photovoltaic platform district is for satisfying different demands, like information acquisition and control function, generally adopts the terminal to be responsible for going upward and master station communication, hangs a metering device again down, like the electric energy meter, is responsible for information acquisition and realizes down communication. With the continuous iteration of new requirements, the mode of 'terminal + table' is adopted in the field of the platform area. When a plurality of electric energy devices such as a photovoltaic acquisition device and a protocol converter exist in a lower photovoltaic platform area, the phenomenon that a plurality of terminals and a plurality of subordinate devices coexist on site is formed. At present, a local communication mode of photovoltaic cell area information acquisition mainly comprises single RS-485 communication and WiFi, two single communication modes are combined, and the mainstream is to organically combine the single wired communication mode and the single wireless communication mode.
For realizing communication and information acquisition of a master station, a 'terminal + meter' mode is generally adopted on the spot in a photovoltaic platform area, but with the appearance of different requirements and new functions, the current single mode cannot meet the new requirements. Various novel terminals and different electric energy meters are combined in a photovoltaic distribution room, so that the equipment in the distribution room is redundant and messy to install on site; meanwhile, some functions can be realized by using the existing equipment, and the added equipment can cause resource waste of the existing equipment on the site and redundancy of newly added equipment, and can also cause messy and wrong wiring on the site, thus easily causing potential safety hazards. The RS-485 communication has the advantages of high success rate of data acquisition, good real-time performance, low error rate and the like, but a special 485 line needs to be laid, the investment cost is high, the line needs to be maintained, and the maintenance workload is increased. The WiFi has the advantages that local area network deployment does not need wires, and the cost of deployment and expansion is reduced. WiFi has the disadvantages of limited communication distance, poor stability, larger power consumption, poor networking capability and poor safety. The field complex application environment which is difficult to process by the single communication mode is adopted, so that the single RS-485 wired communication and the single WiFi wireless communication are organically combined, and the information acquisition of the photovoltaic platform area is realized by establishing the communication mode. However, the communication mode can not meet the requirements for complex field environments, such as the phenomenon that new and old equipment coexist in the replacement transition for equipment with different voltage specifications, and the problem caused by the non-uniform communication mode in the whole photovoltaic platform area.
