The invention discloses a remote transmission fuel gas meter collector system based on WIFI (wireless fidelity). The remote transmission fuel gas meter collector system based on the WIFI comprises a power supply module, an MCU (microprogrammed control unit), a memory module, a wireless module, a WIFI module, a USB-OTG (universal serial bus-on-the-go) module, a card operation module and an RTC (real-time clock) module, wherein the MCU is in communication connection with the power supply module, the memory module, the wireless module, the WIFI module, the USB-OTG module, the card operation module and the RTC module. The WIFI module is used for realizing data interaction between the collector system and a user mobile phone; meanwhile, the USB-OTG module is used as assistance; the data format is simple; the transmission speed is high; the operation requirements of different mobile phones can be met; no connection limit exists; high universality is realized.
