Environment monitor of self-repairing photovoltaic power generation monitoring system and achieving method of environment monitor

The invention discloses an environment monitor of a self-repairing photovoltaic power generation monitoring system and an achieving method of the environment monitor. The environment monitor of the self-repairing photovoltaic power generation monitoring system comprises a redundant module, a fault diagnosis module, a programmable array, a fault detection signal line, a fault diagnosis signal line, a sensor module, a power management module and a communication module. The redundant module comprises a power management redundant module and a communication redundant module, the fault diagnosis module is formed by connecting a fault diagnosis circuit and a microprocessor in series, the programmable array comprises a dynamic reconstruction module and a redundant dynamic reconstruction module, the dynamic reconstruction module is composed of a front amplifying module and a low-pass filter module, and the redundant dynamic reconstruction module comprises two I/O modules, two redundant I/O modules and two switches. The scheme of utilizing the environment monitor for efficiently and stably monitoring the fault and carrying out self-repairing process is provided, the real-time performance of the system is good, and the occurrence that the environment monitor is out of operation when encountering the weather variations and the environment influences is improved.
