Description
Technical Field
The invention relates to the technical field of uninterruptible power supply, in particular to an address allocation method for multiple parallel battery packs in a UPS system and the UPS system.
Background
The UPS (Uninterruptible Power System/Uninterruptible Power Supply) System mainly comprises a UPS host and one or more battery packs connected with the UPS host, wherein the UPS host comprises a Power electronic conversion device which is used for converting external sine alternating current input or direct current battery input into sine alternating current output with stable amplitude and period; the battery pack is used for providing energy storage, and when commercial power alternating current input is interrupted, the power electronic conversion device can convert direct current battery input into sine alternating current output to supply power to the load.
Conventional UPS systems typically use a lead-acid battery (VRLA) pack, and when a UPS system requires the use of multiple lead-acid battery packs, the battery packs may be connected directly in parallel. However, when the UPS system uses lithium batteries as the energy storage power source, in order to implement Battery Management (BMS) for ensuring safety, the UPS host needs to communicate with each lithium battery pack (for example, transmit temperature information, current, capacity, flag bit status, control command, and the like of the battery pack), and thus a unique address needs to be allocated to each lithium battery pack for the UPS host to identify.
For a plurality of lithium battery packs connected in parallel, a currently common address allocation method is to arrange a dial switch (see fig. 1) outside each lithium battery pack, and use the value of the external dial switch as the address of the lithium battery pack. The method specifically comprises the following steps: a user manually dials the dial switches outside each lithium battery pack, the dial switches are set to different values (for example, a four-bit dial switch can represent 2^4 ^ 16 values), the four-bit dial switch represents a unique address of the corresponding lithium battery pack, and the value of the corresponding dial switch is read after the battery pack is powered on; in actual operation, the UPS host inquires each possibly-existing address in turn for all lithium battery packs according to the number of bits of the dial switch (for example, the UPS host may inquire from 0000 to 1111 in a broadcast manner by taking a four-bit dial switch as an example), after receiving an inquiry command including its own address, the lithium battery pack replies to the UPS host to confirm that the lithium battery pack at the address exists, and the UPS determines the addresses of all lithium battery packs connected to the UPS host according to the received reply. However, this address allocation method requires a corresponding dial switch to be provided for each lithium battery pack, and requires a user to manually set a value of each dial switch, thereby causing inefficient allocation and poor user experience.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
According to an embodiment of the invention, an address allocation method for multiple parallel battery packs in a UPS system is provided, which is suitable for applying multiple lithium battery packs in parallel in the UPS system. The structure block diagram of the UPS system is shown in fig. 2, and referring to fig. 2, the UPS host and the battery packs in the UPS system are in a master-slave structure, and the UPS host and the battery packs adopt a communication mode of RS485+ CDBUS, where RS485 has advantages of simple interface, convenient networking, long transmission distance, and CDBUS (collision detection bus) has functions of bus arbitration, collision avoidance, and retransmission. In the UPS system shown in fig. 2, each battery pack is disposed with a CDBUS module for avoiding data transmission collision on the RS485 bus.
Fig. 3 is a flowchart illustrating an address assignment method for multiple parallel battery packs in a UPS system according to an embodiment of the present invention, and the steps in the method will be described separately with reference to fig. 3:
and S31, sending a serial number query command to the plurality of battery packs by the UPS host.
As shown in fig. 2, the UPS host is connected to a plurality of battery packs through the RS485 bus, so in step S31, the UPS host may send a serial number query command to all battery packs on the RS485 bus in a broadcast manner.
And S32, receiving the serial number query command from the UPS host by the plurality of battery packs, reading the serial number of the battery packs, and returning the serial number of the battery packs to the UPS host. According to one embodiment of the present invention, step S32 includes the following sub-steps:
s321, reading a self serial number of each battery pack in the plurality of battery packs after each battery pack receives a serial number query command from the UPS host; then, the serial number of the UPS host is sent to the UPS host through the RS485 bus.
Wherein those skilled in the art will appreciate that different battery packs have unique serial numbers that uniquely identify the respective battery packs.
Step S322, while each battery pack sends the serial number of the battery pack to the UPS host, the CDBUS module of the battery pack monitors the RS485 bus to judge whether the RS485 bus is occupied by other battery packs, if the RS485 bus is occupied by other battery packs, the sending of the serial number of the battery pack is stopped, and the serial number of the battery pack is sent again after the RS485 bus is idle.
Specifically, when a plurality of battery packs on the RS485 bus send their own serial numbers, the CDBUS module of each battery pack compares each bit level of the sent own serial number with the monitored level transmitted on the RS485 bus, if the levels are the same, the battery pack continues to send its own serial number, and if the levels are different, the battery pack stops sending its own serial number, and resends its own serial number when the RS485 bus is idle.
Step s33. receiving, by the UPS host, serial numbers from the plurality of battery packs, generating an address assignment command for each of the received serial numbers, and sequentially transmitting the generated address assignment commands to the plurality of battery packs.
Specifically, after waiting for several bus cycles, the UPS host considers that all battery packs in the UPS system have returned their own serial numbers. Because serial numbers are usually long, if the serial numbers are directly used as addresses of corresponding battery packs, communication time between the UPS host and the battery packs may be occupied in future communication processes, which causes communication inefficiency, for this reason, the UPS host generates a corresponding simplified address for each received serial number (the simplified address is an address with a lower number of bits than the serial number, for example, for a UPS system including 9-16 battery packs, the simplified address may be represented by a four-bit binary number), and combines the serial number and the generated simplified address to generate an address assignment command. Among them, it is necessary to ensure that simplified addresses in all address assignment commands generated are different from each other for uniquely identifying the battery pack. According to one embodiment of the invention, the simplified address may be generated in a manner that generates a random number. After generating the corresponding address allocation commands for all the received serial numbers, the UPS host broadcasts the address allocation commands to all the battery packs on the RS485 bus in sequence.
And S34, receiving an address allocation command from the UPS host by a plurality of battery packs, acquiring a marking serial number and a simplified address from the address allocation command for each received address allocation command by each battery pack, comparing the marking serial number acquired from the address allocation command with the self serial number, and if the acquired marking serial number is the same as the self serial number, taking the acquired simplified address as the self address of the battery pack and storing the address.
In future communication processes, the battery pack can communicate with the UPS host machine by using the simplified address.
Wherein each address assignment command consists of a sequence number and a reduced address, as described above.
The embodiment provides automatic address allocation for a plurality of battery packs connected in parallel in the UPS system, and improves the address allocation efficiency; in addition, the user does not need to set the address manually, so that an intelligent solution is provided for the user, and the user experience is improved.
In the above embodiment, the UPS host may generate a corresponding unique abbreviated address each time a serial number is received, while in another embodiment, the UPS host counts the number of received serial numbers (i.e., the number of all battery packets on the RS485 bus in the UPS system) after receiving serial numbers from all battery packets in the UPS system, and generates a corresponding number of abbreviated addresses different from each other according to the number. Specifically, if the received sequence number is any number from 9-16, the UPS host may generate reduced addresses (i.e., 0000, 0001, 0010, 0011 … …) starting at 0000 until a corresponding number of reduced addresses are generated. After generating the reduced address, a different reduced address may be concatenated after each received sequence number to generate an address assignment command.
