Embodiment Construction
[0073] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.
[0074] Considering the two most common communication connection methods of UPS power supply in the market: relay interface and RS232 interface, the present invention integrates the monitoring device on the communication equipment for the UPS power supply of these two interfaces, and makes full use of the CPU and RS232 interface of the communication equipment. CPLD realizes the monitoring of UPS power supply through the connection of relay interface and / or RS232 interface, and has the advantages of simple implementation, low cost, and convenient control.
[0075] see figure 1 , the figure shows the principle framework of the first UPS power supply monitoring device in the embodiment of the present invention, which is a UPS power supply monitoring device using a relay interface, integrated on communication equipment, including CPU11, CPLD...
