Internet of things equipment network parameter configuration method, Internet of things equipment and system

The invention discloses an Internet of Things device network parameter configuration method, and the method comprises the steps that a current online Internet of Things device serving as a configuration device responds to a first interaction with a user side, and triggers a second interaction with a to-be-accessed Internet of Things device for network parameter configuration, wherein the first interaction at least comprises the step of receiving a second command indication message from the user side, and the message is used for indicating the current online Internet of Things device as a configuration device to perform network parameter configuration on the to-be-accessed Internet of Things device; the second command indication message carries the device information of the to-be-accessed Internet of Things device, wherein the second interaction at least comprises the step of responding to a second command indication message, and configuring network parameters of the device informationof the to-be-accessed Internet of Things device. According to the invention, the current online Internet of Things device and each to-be-accessed Internet of Things device can be used as configurationdevices after accessing the network, so the number of the configuration devices is greatly increased, the efficiency of network parameter configuration is greatly improved, and the problem of networkparameter configuration of a large number of to-be-accessed Internet of Things devices is solved.

Interconnection method for PROFIBUS DP and PROFINET communication networks through sharing storage unit

The invention discloses an interconnection method for PROFIBUS DP and PROFINET communication networks through a sharing storage unit, and the method comprises the steps: (1) the sharing storage unit is divided into a register region, a pipeline region, an IO data region, and a mail box region; (2) a DP communication protocol micro-control unit detects whether there is effective DP configuration locally or not after power-on; (3) the DP communication protocol micro-control unit periodically visits the sharing storage unit to search the effective DP configuration and carry out communication data inter-transmission which serves as the communication between a DP main station maintenance gateway and a slave station; (4) an Ethernet communication protocol micro-control unit maintains PROFINET communication and communication data inter-transmission; (5) the Ethernet communication protocol micro-control unit transmits the DP configuration obtained through an Ethernet to be transmitted to the DP communication protocol micro-control unit through the sharing storage unit; (6) DP bus scanning is started according to the current state of the main station and the DP configuration when the DP communication protocol micro-control unit finds DP configuration updating. The method achieves the protocol conversion and data transmission between a PROFIBUS DP communication network and a PROFINET communication network.
