Distributed power generation system and remote monitoring system thereof

Abstract

The invention provides a remote monitoring system of a distributed power generation system. The distributed power generation system comprises one or more direct-current power sources, one or more inverters, a communicator and a database, wherein the inverter, the communicator and the database are matched with the direct-current power sources; the inverter is connected with a bus cable; one end of the communicator is connected with the bus cable, and the other end of the communicator is connected to the database through the internet. The remote monitoring system comprises a monitoring terminal, a local computer and a mobile application device, wherein the mobile application device and the communicator are connected with each other through a local area wireless communication network and are connected to the database through a wide area mobile communication network via the internet; the monitoring terminal is also connected to the database through the internet so as to obtain monitoring data; the local computer is connected with the communicator, conducts relevant setting on the communicator and displays relevant information in the communicator. According to the remote monitoring system of the distributed power generation system, a bidirectional transmission and information display mechanism is established between the communicator and the database, connection can be realized without an internet access device, and remote monitoring is realized. In addition, information in the database can be sent back to the communicator and displayed so that a customer can use the information conveniently.

Description

technical field [0001] The invention relates to the technical field of monitoring of power generation systems, in particular, the invention relates to a distributed power generation system and a remote monitoring system thereof. Background technique [0002] In the existing distributed power generation system, the power generation unit (DC power supply and inverter) is connected to the communicator to transmit data, and the communicator is connected to the Internet to transmit the data to the database, thereby providing monitoring account usage and realizing remote monitor. [0003] figure 1 It is a schematic diagram of a module connected to a distributed power generation system and its monitoring terminal in the prior art. Such as figure 1 As shown, the power generation system includes multiple DC power sources 101 and their associated inverters 102 , network port equipment 103 , communicator 105 , database 107 and local computer 109 . Wherein, each inverter 102 is conn...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing technology requires the communicator 105 to connect to the Internet 106 through the network port device 103, otherwise it cannot have such a remote monitoring function, and some customers do not have the network port device 103, so this function cannot be realized

In addition, the account information and other data of the monitoring terminal 108 are only stored in the database 107, and other devices such as the communicator 105 do not have the account information of the monitoring terminal 108, which is inconvenient for customers to use, and it will be troublesome if customers forget it.

In addition, in the prior art, the communicator 105 transmits the operating data to the database 107 in one direction, without reversely obtaining and displaying data information from the database 107, especially when the communicator 105 is not connected to the Internet 106
