Embodiment Construction

[0018] The embodiment of the present invention provides a UPS parallel system and a signal transmission method. The control chip in each UPS in the parallel system completes the signal transmission through the receiving and sending chip connected to the control chip and the bus connected to the receiving and sending chip. And acceptance, without the need to complete the corresponding logic circuit based on the peripheral equipment in the control chip through the corresponding logic circuit built based on the peripheral equipment in the control chip, thus solving the problem of UPS in the parallel system in the prior art The logic circuit design of the communication between them is complex and the debugging is difficult.

[0019] The specific implementation manners of a UPS parallel system and a signal transmission method provided by the embodiments of the present invention will be described below with reference to the drawings in the description.

Abstract

The embodiment of the invention provides a UPS (Uninterruptible Power Supply) parallel system and a signal transmission method which aim at solving the problems that logic circuits are complicated in design and comparatively great in debugging difficulty when the logic circuits set up based on peripheral equipment of control chips in UPSs are used for communication in the prior art. The system comprises a plurality of UPSs connected in parallel, and a bus. Each UPS comprises a control chip and a transmitting-receiving chip. The control chips in the UPSs are connected with the transmitting-receiving chips in the UPSs and the transmitting-receiving chips in the UPSs are connected with the bus.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a UPS parallel system and a signal transmission method. Background technique [0002] UPS (Uninterruptible Power Supply, uninterruptible power supply) refers to that when the AC input power supply (used to be called the mains) is abnormal or powered off, it can continue to supply power to the load, and can ensure the quality of the power supply so that the power supply to the load is not affected. device to ensure the reliability of power supply. In some occasions that require high power supply reliability, multiple UPSs are usually connected in parallel to further improve power supply reliability. [0003] At present, each UPS connected in parallel can communicate through the logic circuit built based on the peripheral equipment in the control chip in the UPS. , Random Access Memory) other devices, such as pins, etc. However, these logic circuits are complicated to...
