Embodiment 1

[0042] figure 1 The hardware structure of the present invention is shown. The present invention includes 14 relatively independent functional modules in terms of hardware structure, which can be divided into four aspects according to functions: minimum system, human-computer interaction module, data acquisition and storage module and upper computer interface module. The minimum system is the minimum unit required for the normal operation of the microcontroller, including 101—ARM microprocessor, 102—power supply module, 103—calendar chip, 104—non-volatile memory NAND Flash and 105—volatile memory SDRAM . The data acquisition and storage module includes 106-7 RS485 bus interfaces, 107-4 AD conversion channels, 108-20 GPIO interfaces and 109-SD card interface. The host computer interface includes 111—network interface and 110—serial port console interface. The human-computer interaction interface includes 114—LCD display module, 113—sound card module and 112—GPRS module.

specific Embodiment approach

[0046] The data acquisition module implements data acquisition based on the RS485 protocol. This module implements three protocols used by standard data instruments in the industry, namely DL / T 645 multi-function electric meter communication protocol 203, CJ / T 188 household meter data transmission technical conditions 210 and GB / T 19582 industrial meter based on Modbus protocol Automated Network Specification 204.

[0047] The data collection module collects data from the seven RS485 ports 106 in a timing manner through the data collection program, and encapsulates the data into gateway packets. image 3 The Gateway module data structure is shown. Among them, ServerIP 301 describes the unique identification code of the gateway device, Location String 302 describes the server address corresponding to the gateway device, Port[7] 306 describes all the information involved in the independent data collection of the seven ports, and realizes functions such as data collection timing...

Abstract

The invention discloses a method for achieving an Internet of things intelligent data gateway. The gateway achieves data collection in a device and the data are sent to a server at regular time or the server obtains the data at a certain fixed time interval. According to the gateway device, the defects that a traditional gateway device is complex in upper computer software programming, low in data collection speed, low in real-time performance and integrity of data collection and the like are overcome.

Description

technical field [0001] The invention relates to a manufacturing method of an Internet of Things intelligent data gateway, which belongs to the field of electronic communication, and in particular relates to a method for realizing an Internet of Things intelligent data gateway system. Background technique [0002] In modern industrial production, energy management systems based on Internet of Things technology are getting more and more attention: use sensors to measure the use of energy in the factory area, then collect sensor data through gateway devices and transmit them to the information management center for storage, and finally pass The energy management platform conducts management tasks such as centralized monitoring and energy consumption analysis, which facilitates plant managers to grasp the monitoring data of each metering point in real time, thereby effectively realizing energy and resource management. [0003] The gateway device is one of the important component...
