Embodiment Construction

[0027] Combining with specific examples Figure 1-6 Describe this plan,

[0028] The hardware system of the IoT mobile terminal equipment consists of an ARM9 processor connected to an RFID reader module, a WiFi module, a GPRS module, a GPS module and a two-dimensional barcode module. Among them, the GPRS, GPS, and one-dimensional barcode modules are connected through UART, the WiFi module is connected through SDIO, and the RFID reader is connected to the ARM9 processor through USB ( figure 1 ).

[0029] The system software architecture is composed of the interface driver program of each module, the memory management unit driver program and the upper layer application program. The drivers of each hardware interface are independent of each other, and are logically connected with the memory management unit, forming a topology centered on the memory management unit, see figure 2 . The memory management unit communicates with the upper-layer application in the form of netlink,...

Abstract

The invention relates to a method for processing an embedded multi-module Internet of Things mobile terminal device data system. The system comprises an application unit, a memory management unit and hardware modules, wherein the memory management unit comprises a Linux kernel module, the hardware modules comprise hardware kernel modules, a communication mode is established by the memory management unit between the application unit and the hardware modules, and each of the hardware modules communicates with the outside through an antenna. According to the method for processing the embedded multi-module Internet of Things mobile terminal device data system, a memory management unit driving module is designed to communicate with the rest of the hardware modules in a driving mode, and simultaneously a netlink mode is utilized to provide only one communication channel between an underlying driver and an upper-layer application program to control the distribution and collection of data. By means of the method for processing the embedded multi-module Internet of Things mobile terminal device data system, the programming is extremely flexible, and the program efficiency is extremely high.
