Abstract

The invention relates to the field of smart monitoring and particularly relates to a communication manager. For the problem that serial ports of the communication manager are low in data processing rate and limited in data processing quantity, a joint design of a field programmable gate array FPGA and an embedded micro control unit MCU is employed for a main module. The FPGA is equipped with a plurality of serial ports and is used for receiving data and preprocessing the data. The MCU is connected with the FPGA and is used for receiving the preprocessed data and analyzing the preprocessed data. Compared with the traditional communication manager, the communication manager system has the advantages that the FPGA preprocesses the collected data, so the data processing pressure of the micro control unit is reduced; moreover, high-efficiency task scheduling is carried out in real time through adoption of an embedded real-time operating system, so the data processing efficiency is improved, the timeliness of the communication manager is improved, and the data processing capability of the communication manager is also improved; and the serial ports of the communication manager are easy to expand, so GPRS wireless communication also can be realized.

Description

technical field [0001] The invention relates to the field of intelligent monitoring, in particular to a communication management machine system based on FPGA+STM32. Background technique [0002] Most of the current communication management machines use the PowerPC series processors provided by Motorola as the main chip to realize the communication management machine technology. The related architecture is as follows: figure 1 The schematic diagram of the structure of the PowerPC series communication management machine is shown. [0003] Among them, the MPC chip, FLASH, SDRAM, etc. form an embedded system to realize the processing of all protocols and data forwarding. Multi-chip CPLD cooperates to realize multi-channel decoding and LCD driver for serial port reception. Serial port data acquisition realizes serial port protocol through serial port protocol chip. Go to FIFO. Because all protocol data processing is done by the main chip, when more serial ports need to be expan...
