Embodiment 1

[0031] A parameter synchronization method provided by an embodiment of the present invention, such as figure 1 shown, perform the following steps:

[0032] 101. The current device in the parallel system acquires its own system parameters, where the system parameters are parameters used during the operation of the current device;

[0033] 102. The current device reads a synchronization parameter corresponding to the system parameter;

[0034] 103. When the synchronization parameter indicates that the system parameter needs to be synchronized, broadcast the system parameter to all other devices in the parallel system through the RS485 bus or the CAN (Controller Area Network, Controller Area Network) bus to trigger All other devices in the parallel system use the system parameters during operation.

[0035] In the parameter synchronization method provided by the embodiment of the present invention, a device in the parallel system obtains its own system parameters, and reads the...

Embodiment 2

[0050] The present invention adopts the masterless mode, that is, the status of each device in the parallel system is equal, and the function of synchronizing parameters can be achieved through any device, and it is only necessary to pass through the LUI before selecting a device for parameter setting. Set the function of parameter synchronization to enable this function.

[0051] When solving the problem of data interaction between various devices in the parallel system, since there are multiple devices in the communication, it is necessary to use the bus method to realize the communication. Currently, the bus communication method commonly used in the industry is relatively simple and easy-to-use RS485 or CAN ( Controller Area Network, controller local area network), to realize the transmission of parameters between various devices. In this way, it is necessary to define an application layer protocol (such as CAN) to interactively set data, and define a signal for each parame...

Abstract

The invention, which relates to the parallel machine system, discloses a method for parameter synchronization and apparatuses. The method comprises the following steps that: current equipment in a parallel machine system obtains a system parameter of the parallel machine system itself; the current equipment reads a synchronization parameter corresponding to the system parameter; and when the synchronization parameter indicates that the system parameter needs to be synchronized, the system parameter is broadcasted to all other equipment in the parallel machine system by an RS485 bus or a controller area network (CAN) bus, so that all other equipment in the parallel machine system is triggered to use the system parameter during the operation processes of all other equipment. According to the embodiment of the invention, the method and the apparatuses are mainly applied to a processing process of automatic parameter synchronization in a parallel machine system.

Description

technical field [0001] The present invention relates to the technical field of parallel systems, in particular to a parameter synchronization method and device. Background technique [0002] The parallel system can support multiple devices, and the system parameters in each device must be consistent. In the application scenario of UPS (Uninterruptible Power Supply, uninterruptible power supply), the most common system is a parallel system, and usually a parallel system can support parallel connection of multiple UPSs. Another usage scenario is that the user first uses a single UPS, and then adds a UPS to form a parallel system due to capacity expansion. Under normal circumstances, the consistency of the corresponding UPS parameters in each UPS in the parallel system is very important for the UPS system, and there are many parameters that need to be set for the UPS. In the on-site deployment, it is generally necessary to set corresponding parameters for each UPS to ensure t...
