Problems solved by technology

[0003] Existing data gateways are mainly designed for a specific protocol conversion process, only support a single protocol conversion process, poor compatibility
When the communication protocol changes, the parsing and conversion program needs to be replaced again, which will lead to repeated development and waste a lot of manpower and material resources; in addition, the existing data gateway uses a microprocessor with a clock frequency of less than 80MHz in the hardware structure, and the processing speed is slow , can support few interfaces, cannot support high-speed communication, and has low reliability

Embodiment Construction

[0046] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] Microgrid data gateway devices, such as figure 1 As shown, including: main controller, power supply module, storage module, watchdog circuit, buffer module and drive module.

[0048] The drive module is used to receive the microgrid data through the RS485 interface and the RS232 interface respectively, drive the RS485 interface and the RS232 interface to work in full duplex, and transmit the received microgrid data to the main controller through the buffer module.

[0049] The main controller is used for protocol conversion of microgrid data.

[0050] The power module is used to provide +5V and +3.3V power for the main controller.

[0051]One end of the drive module is connected to the RS485 interface and the RS232 interface, the other end of the drive module is connected to one end of the buffer module, and the other end of the b...

Abstract

The invention relates to a micro-grid data gateway device and a data converting method. The device includes a main controller, a buffer module and a driver module, wherein the driver module is used to respectively receive micro-grid data by an RS485 interface and an RS232 interface, drive the RS485 interface and the RS232 interface work in full duplex, and transmit received micro-grid data to the main controller through the buffer module. The data converting method comprises: collecting a source protocol data frame data by an Internet to transmit it to the main controller, or collecting the source protocol data frame data by the RS 485 interface or the RS232 interface to transmit it to the main controller through the driver module and the buffer module, performing, by the main controller, a protocol conversion on the source protocol data frame data, and transmitting it to the Internet by Ethernet or to the RS 485 interface and the RS232 interface by the buffer module and the driver module.

Description

technical field [0001] The invention belongs to the technical field of data gateways, and in particular relates to a microgrid data gateway device and a data conversion method. Background technique [0002] In the production of modern enterprises, the management and operation system of the enterprise generally adopts the communication network with the computer as the main node, mainly based on the TCP / IP protocol; at the same time, the automation system of the production line generally adopts the control and communication network with the PLC as the main node. The commonly used field bus protocol is how to realize data communication between different application systems, open up data channels between different communication protocols, and perform data analysis, storage, and forwarding functions, such as the rapid release of production instructions and the rapid release of production status, so that Improving the production efficiency of enterprises is an objective requiremen...
