Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] The present invention provides an address allocation method, which can be applied to various RS485 communication systems. For example, the communication system may be a base station communication system or a lead-acid lithium battery communication system. The communication system includes a master device and at least A raw slave device such as figure 1 As shown, the master device and the original slave device are connected in parallel through th...

Abstract

The invention discloses an address allocation method. A current slave device executes the following steps of receiving an active addressing instruction sent by a master device through a bus network, the active addressing instruction comprising at least one original address; if the local storage medium does not contain the allocated address, receiving a reply instruction which is sent by the calibration slave equipment through the bus network and contains the allocated address within the timeout period; determining at least one to-be-allocated address according to the at least one original address and the allocated address; and determining a target address from the at least one to-be-allocated address, and storing the target address as an allocated address in a local storage medium. According to the address allocation method provided by the invention, the target address is automatically determined without adding dialing equipment, cost is effectively reduced, the determination process is simple and efficient, and the address allocation method is suitable for all to-be-allocated slave equipment and has good compatibility.

Description

technical field [0001] The invention relates to the technical field of electronic communication engineering, in particular to an address allocation method. Background technique [0002] In order to realize the communication between the master device and the current slave device in the RS485 communication system, the master device needs to assign an address to each current slave device. At present, the master device usually needs to rely on hardware DIP switches to assign addresses to the slave devices to be assigned. Since the hardware DIP switches need to be manually set, there are problems of high cost, complicated operation, and prone to allocation errors, and the number of addresses is limited by the DIP switches. Limitation, not applicable Assign addresses for multiple current slaves. Alternatively, the master device needs to send a series of protocols to the slave device to be allocated in advance, and the slave device to be allocated needs to be modified, which requi...
