Embodiment Construction

[0028] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] The invention provides a WIFI-based remote gas meter collector system, such as figure 1 As shown, it includes power supply module, MCU, memory module, wireless module, WIFI module, USB-OTG module, card operation module and RTC module.

[0030] Among them, the power module is used to provide adaptive power for other modules in the collector system. In the embodiment of the present invention, the power supply module includes two No. 5 800mAh lithium-ion rechargeable batteries (with a voltage of 3.7-4.2V), one of which is used as the main battery to supply power to other modules, and the other is used as a backup battery. The main battery is stepped down to 3.3V by an LDO (low dropout regulator) chip, and then supplies power to the MCU, memory module, wireless module, USB-OTG module and RTC module, and supplies power to the WIFI via an LDO chip. Th...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of remote gas meters, and in particular relates to the design of a remote gas meter collector system based on WIFI. Background technique [0002] With the development of remote meter reading technology, the convenient and fast hand-held meter reading method is more and more popular in the market. The STM32 platform is an emerging high-performance embedded processor. At present, many domestic gas meter manufacturers are evaluating or replacing it. On the platform, the platform is convenient for C language development, has rich hardware resources, and is suitable for handling complex application tasks of remote gas meter collectors. [0003] After the user uses the collector to read the remote gas meter, it may also need to send the corresponding reading to the mobile phone and the background data system for subsequent processing. In the prior art, the Bluetooth module is usually used to realize the communica...
