[0002] The safety of the power supply system is an important part of ensuring the stable operation of highway toll stations. In order to ensure a high power supply reliability, highway power supply systems are equipped with uninterruptible power supplies (UPS). When the three-phase power of the city power is missing, the UPS input is abnormal, or the UPS itself fails, the UPS host will issue an abnormal alarm, but the alarm sound is small and often difficult to be detected, which may cause the UPS battery to run out and cause power outages, causing unnecessary losses. At the same time, the UPS control motherboard has a small driving current and cannot directly drive a large-power alarm device. In addition, arbitrarily connecting and modifying the UPS control motherboard is not conducive to the stable operation of the UPS. Therefore, it is very necessary to use relevant technical means to non-destructively expand the alarm function. Utility Model Content

The UPS host control board 10 is connected to the UPS abnormality monitor 11 through an RS232 serial port line. The UPS abnormality monitor 11 is responsible for collecting, reading, and analyzing the status information of the UPS host control board and outputting an alarm control signal. The signal detection circuit module 12 is responsible for detecting the signal output by the UPS abnormality monitor 11 and converting it into a digital signal that can be collected by the controller module 13. The signal output by the UPS abnormality monitor 11 is a voltage signal or a switch signal. The signal detection input end of the signal detection circuit module 12 is electrically connected to the alarm signal output end of the UPS abnormality monitor 11. The IO pin of the controller module 13 is electrically connected to the signal detection judgment output end of the signal detection circuit module 12. The controller module 13 is used to collect the detected digital signal and send a single-chip microcomputer control signal. The relay module 14 is responsible for converting the single-chip microcomputer control signal into a relay switch signal. The control signal input end of the relay module 14 is connected to the IO pin of the controller module 13.

[0030] Working principle: When the UPS main engine detects that the mains power is missing phase (or the UPS input is abnormal or the UPS itself fails), the UPS main engine triggers the phase-loss protection, and the UPS main engine control board 10 automatically controls to disconnect the input line. At the same time, the main engine issues an alarm. Then, the UPS abnormality monitor 11 communicates with the UPS main engine control board 10 in real time through the RS232 serial port line. The UPS abnormality monitor 11 will also obtain the fault information and output a voltage signal (or a switch signal) at its alarm output port. The signal will be connected to the signal detection circuit module 12 for collection, processing and analysis, and converted into a control signal. The controller module 13 can collect the digital signal. After that, the controller module 13 collects the fault signal and controls a certain IO port to send a control signal.

At this time, the relay signal normally open output terminal NO of the relay module 14 is connected to the output common terminal COM, the voice alarm module 15 is powered on and a high-pitched alarm sound is emitted. At the same time, the relay signal normally closed output terminal NC is disconnected from the output common terminal COM, the 4G power off alarm module 16 loses the power supply 17, triggering the power off alarm function, and notifying the client 18 of the alarm through phone calls, text messages, etc.
