A method, device and system for discovering and controlling embedded network equipment

Abstract

The invention discloses a method for discovering and controlling an embedded access network device. The method includes sending a device retrieving message to a designated multicast group; receiving and storing all retrieving response messages sent by an embedded device in the multicast group, the retrieving response messages carry relevant information of the embedded device; setting a control command supported by the embedded device according to the relevant information; and utilizing the control command to control the embedded device and receiving a control result feedbacked by the embedded device. The invention further discloses a device and a system for discovering and controlling the embedded access network device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for discovering and controlling embedded network access equipment. Background technique [0002] At present, with the rapid development of IT technology, more and more embedded devices are applied to people's daily life and work. With the continuous maturity of Internet of Things technology, more and more devices need to be controlled and managed. Due to The number of devices is large and the connection between devices is complex, and the number of devices and their interrelationships are constantly changing, which makes it more and more difficult to control these devices in a unified manner. [0003] Especially for some large production enterprises, hundreds of devices may span different networks, and different devices also have corresponding sub-level devices. The device network is complex and changeable, which makes the control and management...

[0002] At present, with the rapid development of IT technology, more and more embedded devices are applied to people's daily life and work. With the continuous maturity of Internet of Things technology, more and more devices need to be controlled and managed. Due to The number of devices is large and the connection between devices is complex, and the number and interrelationships of devices are constantly changing, which makes it more and more difficult to control these devices in a unified manner.

[0003] Especially for some large production enterprises, hundreds of devices may span different networks, and different devices also have corresponding sub-level devices. The device network is complex and changeable, which makes the control and management of devices more difficult. Moreover, among them Many devices may not provide direct operation methods, such as various dumb terminals. A dumb terminal is a terminal that only depends on the host for processing. It is a terminal without input and output devices such as keyboards, monitors, and touch screens. Therefore, dumb terminals It is more difficult to control and manage equipment such as

[0004] At present, the UPnP protocol, as a widely used protocol, can realize peer-to-peer network connections (P2P) between various smart devices, wireless devices and personal computers, but because the UPnP protocol introduces the SOAP protocol, and its communication protocol The XML-based HTTP / HTTPU / HTTPMU protocol is selected, which is equivalent to introducing a small HTPP server. At the same time, the parsing of the XML protocol is relatively complicated, but for various small embedded devices and dumb terminal devices, most of them The device may not support the complex UPnP protocol mentioned above, so the UPnP protocol is not suitable for communication and control of small embedded devices such as microcontrollers
