Method for achieving dynamic registration based on Subset-037 protocol

The invention relates to a method for achieving dynamic registration based on a Subset-037 protocol. According to the method, equipment B connected with equipment A is dynamically registered on the equipment A, safe and reliably communication is carried out through the Subset-037 protocol, and the method specifically comprises the following steps that 1) the equipment B carries out dynamic registration on an information collecting module of the equipment A; 2) the information collecting module of the equipment A transmits the collected information of the equipment B to a safety function module of the equipment A, and sends the state of the equipment A to the equipment B; 3) safe connection is built between the equipment A and the equipment B through the state and the information. Compared with the prior art, the method has the advantages of being good in safety performance, convenient to use, high in flexibility and the like.
