s406, comparing whether the serial numbers are consistent, namely comparing the current serial number with the self serial number after the child node receives the current serial number information;

s408, if the serial numbers are consistent, answering, and if the serial numbers of the subnodes are consistent with the current serial number sent by broadcasting, considering that the subnodes are under the current gateway serial port;

s410, adding the node into a 485 address queue to be distributed (corresponding to the first list);

s412, starting from address 1, sending probe information (corresponding to the first probe command) to all nodes;

s414, normal response or messy codes exist;

s416, the address is considered to be occupied;

s418, increasing the address by 1, and continuing to detect;

s420, the child node does not respond, for example, the gateway does not receive response information returned by any child node within a preset time length;

s422, the address is considered to be unoccupied;

s424, selecting a node of an address to be distributed (corresponding to the target node of the address to be distributed determined from the first list), and setting a 485 address;

s426, address setting is successful;

s428, the node is added to the gateway configuration.

s502, a sequence number list (corresponding to the aforementioned target list) is imported.

S504, send a sequence number broadcast instruction to the child node, for example, the gateway sends the current sequence number information to all child nodes by broadcasting, and repeatedly sends the current sequence number information three times.

S506, judging whether the child node has a response;

in the step, all the child nodes receive the serial numbers sent by broadcasting, and the child nodes compare the serial numbers with the self serial numbers after receiving the serial number information; if the serial number of the child node is consistent with the serial number sent by broadcasting, the node is considered to be under the current gateway serial port;

the child node initiates a response to the gateway, and the response content comprises the current 485 address, the serial number information and other contents.

S508, if the determination result in step S506 is negative, that is, the gateway does not receive the response from the child node, adding the serial number to the "serial number does not exist" list (corresponding to the second list).

And S510, if the judgment result in the step S506 is yes, namely the gateway receives the response of the child node, adding the serial number into the 485 address queue to be allocated, and waiting for the 485 address to be allocated again.

Steps S502-S510 are repeated until all sequence numbers are traversed.

And S512, ending.

Optionally, a "non-existent sequence number list" may be derived subsequently, the line connection may be checked, or whether the node is a child node of another gateway may be confirmed.

Fig. 6 is a schematic flow chart of automatic node address setting according to an embodiment of the present invention, which includes:

assume that the sub-node 485 address is set to 1-254 (corresponding to the aforementioned target address range), and 255 is a broadcast address.

S602, initializing the 485 address to be allocated to 1 (or other addresses);

s604, determining whether the 485 address to be currently allocated is within an address range allowed to be allocated, for example, determining whether 1< =485 address < =254 is satisfied;

s606, if the determination result in the step S604 is yes, transmitting instruction information (corresponding to the first probe instruction) to the address 1 child node;

if the determination result in the step S604 is negative, the process can be ended;

s608, judging whether a child node responds after the address in the step S606 is used for sending the instruction information;

s610, if the determination result in the step S608 is yes, it is determined that the 485 address already exists, that is, the node of the 485 address already exists, and the process proceeds to step S612;

s612, automatically increasing 1 to the 485 address to be distributed currently, and returning to the step S604;

s614, if the judgment result in the step S608 is negative, the 485 address is considered to be unoccupied; at this time, a node sequence number is selected from the list to be allocated (corresponding to the aforementioned first list);

in the above steps S602-S614, the gateway sequentially sends the instruction information to the designated address starting from address 1, and waits for the response of the child node, optionally, the gateway may repeatedly send the instruction information three times;

if the gateway can normally receive the response of the child node within three times, the address is considered to be occupied;

in practical application, if the gateway receives a child node response within three times but does not complete the command packet, the address is considered to be occupied and a conflict address exists;

then, the address of the gateway child node is increased by 1, and the steps S604-S612 are repeated until no child node responds, so that the 485 address is proved to be unused.

S616, setting a 485 address to the specified serial number;

after finding out the 485 addresses of the unoccupied child nodes, the gateway sets a new 485 address to the appointed child node (such as the node N) through a broadcast instruction;

s618, determining whether the child node (e.g., the node N) has a response, for example, after the gateway sets a new 485 address to the designated child node, the gateway sends instruction information to the new 485 address, and if there is a child node returning response information, it is determined that the 485 address is successfully set;

s620, when the gateway receives the response information sent by the child node (such as the node N), the new 485 address is considered to be successfully set;

s622, storing the information of the node (such as the node N) into gateway configuration; that is, the information of the sub-node serial number (namely the serial number of the node N), 485 address and the like is stored in the gateway configuration;

s624, starting to inquire child node information at regular time; after the information such as the serial number and 485 address of the child node is stored in the gateway configuration in step S622, the gateway can send an event to the platform to prompt that the child node is on line, so that the child node data can be queried;

and S626, ending.

In the above embodiment, the 485 address is automatically configured for the 485 gateway child node by importing the serial number list, and the 485 child node is automatically added to the gateway host by importing the serial number of the child node, so that the effect of one-key deployment can be achieved.

In the related art, there is a method for acquiring 485 addresses of all current nodes of a bus by generating response delay time through the id of the node itself, and there are some approaches of id values, which result in insufficient delay and failure to receive information of all nodes of the bus in time, and compared with the related art, the embodiment of the present application has the following advantages: 1) And scanning the 485 gateway sub-node two-dimensional code through a code scanning gun to obtain a sub-node serial number. Executing before project deployment; 2) The serial number is led into the gateway through 485 gateway web, technicians in subsequent projects do not need to be concerned about the problem of sub-node configuration, and the gateway automatically sets addresses of sub-nodes according to the idle-open serial number to avoid conflict and automatically reduces the configuration work of the technicians on line.
