Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings of the specification.

[0016] A system that realizes centralized management and remote management of off-grid photovoltaic power systems, including a management center, more than one terminal and more than one off-grid photovoltaic power system, one terminal corresponds to more than one off-grid photovoltaic power system. The management center mainly includes a PC, which joins the GPRS wireless public network (GPRS wireless public network IP can be purchased from the service provider), GPRS communication follows the message format in the DL / T 634.5101-2002 implementation rules ; The PC is installed with man-machine communication software, such as network configuration. The terminal includes a first CPU and a charging and discharging unit, a first radio frequency module, a first solar panel, a first battery, and a GPRS module; the first radio frequency module of the terminal...

Abstract

The invention discloses a system and a method for realizing centralized management and remote management over off-grid photovoltaic power systems. The method comprises the following steps that: a personal computer (PC) of a management center accesses the Internet to find terminals according to the general packet radio service (GPRS) wireless Internet access addresses of the terminals and read the information of the terminals or transmit an instruction to each terminal; each terminal finds a corresponding off-grid photovoltaic power system according to the address of a wireless radio frequency module in each off-grid photovoltaic power system; the information of each photovoltaic power system is acquired and stored in a corresponding terminal through wireless radio frequency communication for the management center to query, or an instruction is transmitted to each off-grid photovoltaic power system; and after receiving the instructions from the terminals, each off-grid photovoltaic power system measures and processes own data, and performs many kinds of control. Therefore, the centralized management and the remote management over the off-grid photovoltaic power systems are realized by the PC, and a prompt can be given when the systems are required to be manually managed and maintained to improve the running reliability of the systems.

Description

Technical field [0001] The invention relates to an off-grid photovoltaic power supply system. Background technique [0002] At present, the off-grid photovoltaic power system known in the market is composed of solar panels, batteries and controllers, all of which are free of management and maintenance. The disadvantage is that when people use more remote and dispersed off-grid photovoltaic power systems (such as solar street light systems), it is inconvenient to understand the operating conditions of the photovoltaic power system, and they do not know when the system requires manual management and maintenance. Summary of the invention [0003] One of the technical problems to be solved by the present invention is to provide a system that realizes centralized management and remote management of off-grid photovoltaic power system, realizes centralized management and remote management, and can be reminded when the system needs manual management and maintenance to improve system opera...
