Problems solved by technology

[0005] Traditional BACnet / Modbus gateways can only realize data exchange through data sharing. This "opaque" method is not only difficult to integrate and manage Modbus devices, but also must prepare large-capacity storage for a large amount of shared data for temporary storage

Embodiment Construction

[0022] The invention relates to a Modbus and BACnet Ethernet protocol conversion device and method based on routing function.

[0023] Such as figure 1 As shown, the device of the present invention includes a control unit, a network interface, a serial interface, and a working power supply. The network interface and the serial interface are connected to the control unit, and the working power supplies power to the control unit, the network interface, and the serial interface.

[0024] The control unit can be realized by the micro-processing circuit 1m3s6911+ circuit. The network interface can be an RJ45 standard network interface. The serial interface is RS485 standard interface. The working power supply rectifies and filters the input AC power and outputs it to other units.

[0025] Because the present invention will communicate with software or equipment of two different communication protocols of BACnetEthernet and Modbus simultaneously, so multitasking function is neede...

Abstract

The invention discloses a routing function-based apparatus for mutual conversion of Modbus network equipment and building automation and control networks (BACnet) Ethernet network equipment and a conversion method thereof. The conversion apparatus comprises an ethernet network interface, a control unit, a serial interface and a working power supply. The working power supply is respectively connected with the network interface, the control unit, and the serial interface as well as is used for supplying power for the network interface, the control unit, and the serial interface. The control unit is used for carrying out parsing, route orientation and repackaging on a Modbus message and a BACnet Ethernet message. The network interface is connected with the control unit and is used for receiving message data sent by the control unit and forwarding the message data to the ethernet network. And the serial interface is connected to the control unit and is used for receiving message data sent by the control unit and forwarding the message data to a Modbus network. According to the invention, the apparatus can be used conveniently with low power consumption; Modbus equipment can be directly packaged into BACnet equipment; transparent management, operation and debugging on the Modbus equipment in the BACnet environment can be realized; and an application value of the system integration is also improved.

Description

technical field [0001] The present invention relates to a Modbus and BACnet Ethernet protocol conversion device and conversion method based on the routing function, which can be applied to network equipment with the BACnet Ethernet communication protocol as the main communication protocol, and the Modbus equipment is routed and packaged into BACnet equipment, which is implemented in Direct management of Modbus devices in the BACnet environment, thus bringing greater application and development value to the integration of BACnetEthernet devices and Modbus devices. Background technique [0002] Since the first intelligent building appeared in the 1980s, the intelligent building system has continuously adopted the latest technology for system integration. The building automation network protocol BACnet (Building Automation and Control Networks) is a standard for the field of building automation. With its advanced technology, perfect architecture and open concept, it has been wi...
