Brief description
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is that the present invention realizes the FB(flow block) of the method distributed from the machine network address based on NFC communication.
Detailed description of the invention
Embodiment is as it is shown in figure 1, the present invention realizes comprising the steps: from the method for machine network address distribution based on NFC communication
Step one, being arranged side by side and be smaller than 10CM by some network drives from machine, under original state, all NFC communication modes from machine network drive are set to reception pattern；
Step 2, by main frame to First from machine send order, First starts decoding after machine receives Handshake Protocol, when confirm be main frame be sent to this from the Handshake Protocol of machine when, the protocol address receiving is entered as this from the network address of machine from the network drive of machine by First；
Step 3, First is set to sending mode from the NFC communication mode of machine network drive, and this is sent to after the network address of machine adds one neighbouring from machine by NFC communication mode, it is sent completely rear First and change back reception pattern from the NFC communication mode of machine network drive；
Step 4, neighbouring receive first from machine by network drive behind the network address that machine is issued, make decoding response, and check the network address whether big than the network address of oneself receiving, do not respond in this way；As otherwise the network address receiving being set to the network address of oneself；
Step 5, the network address is set from machine, the NFC communication mode of network drive is set to sending mode, and this is sent to after the network address of machine adds one neighbouring from machine by NFC communication mode, reception pattern should be changeed back from the NFC communication mode of machine network drive after being sent completely, make decoding response adjacent to receiving this from machine by network drive behind the network address that machine is issued, and check the network address whether big than the network address of oneself receiving, do not respond in this way；As otherwise the network address receiving being set to the network address of oneself；
Step 6, repetition step 5, until all network address from machine network drive are assigned.
Preferably, when adjacent to after from the machine transmission network address, judge not receive decoding response by timing, it is then automatically upgraded to the main frame of sub-network, and will former master network add to subnet by the follow-up of sequence of addresses connection from machine, in sub-network, repetition step 2 is to step 6, until the network address from machine network drive of all-ones subnet network is assigned.
This method utilizes the communication characteristic of NFC, discharge all in network side by side with 10CM spacing from the network drive of machine, make other network drives that a certain network drive can automatically around identification, and automatically connected for respectively arranging network from the network drive of machine by algorithm, and the network drive being newly added can be made to automatically obtain the network address, without very important person for arranging, intelligence completely.
The NFC communication of original state all-network driver is arranged to reception pattern, can only receive information and can not send information.Now main frame sends an address to First from machine, First performs the distribution of automatic network address after machine completes decoding and confirms the network address that main frame sends, and the network address of oneself is entered as the network address receiving, after NFC is set to transmission state, this being sent to after the network address of machine adds one neighbouring network drive, NFC communication after transmission is set to reception pattern again.
If the address that network drive around receives is not responding to greatly first than the network address of oneself, if not then the network address of oneself being entered as the address that receives, and the action before repeating, until all network address from machine network drive are assigned in network.
And when certain from machine network drive nonreply fault, whole network can be automatically separated into sub-network, do not affect the work of network other network drives interior；When addition one new network drive, sub-network merges into a network again and the network drive for being newly added enrolls the network address.
This method compares traditional bus communication form (CAN, RS485 bus, ethernet bus), NFC communication short range transmission speed is fast, and bus need not repair bus after being broken, as long as main frame accesses each sub-network and just can continue to control whole network, achieve network drive automatically identify, the function of automatic network-building, eliminate the debugging link of complexity in production scene, save substantial amounts of time and human resources, improve the operating efficiency of networking.
