Embodiment 1

[0039] Such as Figure 1 to Figure 15 and Figure 17 to Figure 20 As shown, a multi-protocol data acquisition gateway adopts an embedded system structure based on ARM+DSP, including a hardware application platform, a system software platform and application software.

[0040]The hardware product platform is divided into modules, the main module is the SOC module, and the other separate modules are the data acquisition module and the power supply module. Communication between modules uses standard CAN interface. System hardware mainly includes microprocessor core circuit, analog input and output circuit, digital input and output circuit, video signal acquisition circuit, audio signal acquisition circuit, thermocouple, thermal resistance signal acquisition circuit, Ethernet interface circuit, serial port circuit, CAN The bus interface circuit and industrial bus adopt PROFIBUS interface circuit, CF card memory circuit, power supply and peripheral circuit. Each interface and ap...

Embodiment 2

[0061] Similar to Embodiment 1, the difference is that the Ethernet communication process is adopted, and when the Ethernet communicates with the database, it is first judged whether to receive data or send data from the database. If the data is received from the outside, the IP packet is received, the IP packet is parsed and sent to the TCP layer, and the TCP layer parses the received data packet and sends it to the application layer, and the application layer sends the parsed data to the database for storage . When choosing to send data, the data transferred from the database is packaged at the TCP layer, then IP is packaged, and finally transmitted to the outside, so as to complete the communication with the Ethernet, such as Figure 1 to Figure 14 and Figure 16 to Figure 20 shown.

Abstract

The invention relates to a device for connecting different types of exchanging system networks, in particular to a multiprotocol data acquisition gateway which adopts an ARM+DSP-based embedded system structure and comprises a hardware application platform, a system software platform and application software. A memory is used as a data server to set up a database; buses with different protocols access to the database to realize the protocol transformation, the data sharing and the communication among different networks with different protocols; the hardware application platform is provided with a universal interface so as to acquire standard and nonstandard current-voltage signals and audio-video signals in the industrial field or acquire the data of equipment with standard communication protocols in the industrial field and further realize the protocol transformation and provide a comprehensive data transformation scheme from a physical layer and a data link layer to an application layer, wherein the application layer is a single network protocol, which facilitates enterprise data intercommunication and reduces the application cost. The multiprotocol data acquisition gateway is applied to the electric power, the mine and the like to realize the remote centralized automatic data acquisition and is used for transforming different communication protocols of equipment in a system to the unified communication protocol.

Description

technical field [0001] The invention belongs to a device for connecting different types of switching system networks, and in particular relates to a multi-protocol data collection gateway. Background technique [0002] At present, with the development of computer, communication, network and other information technologies, information exchange technology has been widely used in factories and enterprises. Therefore, it is necessary to establish a comprehensive automation network platform including all levels from the industrial field equipment layer to the control layer and management layer. , Establish an enterprise information system based on industrial control network technology. Although Ethernet has been widely used in upper-middle-level network communications such as management and control layers in the industrial control field, due to the particularity of industrial applications, industrial Ethernet has high requirements for real-time performance, anti-interference and ...
