Embodiment 1

[0029] When the device 1 in the AC panel (such as a lightning arrester) fails, its fault data or switching value is collected by the AC monitoring unit. After the CPU in the AC monitoring unit judges that the data or switching value is a fault phenomenon, it will send the fault data through the RS232 / 485 communication interface. The data is uploaded to the programmable logic controller PLC. After analyzing the data, the PLC judges the location of the device 1 that caused the fault, controls the fault buzzer to sound an alarm, and uploads the data to the touch screen display through the RS232 / 485 interface at the same time: first Display "System Fault" on the main screen, such as Figure 4 , and secondly, display the specific fault content on the fault query screen in the form of lighting up the optical name plate (such as Figure 5 ), and at the same time query the screen at the fault location (such as Image 6 ) shows that the screen where the faulty device is located is an ...

Embodiment 2

[0031] When the device 2 (such as the inverter module) in the emergency lighting panel fails, its fault data or switching value is collected by the module monitoring unit. After the CPU in the module monitoring unit judges that the data or switching value is a fault phenomenon, it communicates through RS232 / 485 The interface uploads the fault data to the programmable controller PLC. After analyzing the data, the PLC judges the location of the device 2 that caused the fault, controls the fault buzzer to sound an alarm, and uploads the data to the touch screen through the RS232 / 485 interface at the same time Display: first display "system failure" on the main screen, (such as Figure 4 ), followed by displaying the specific fault content on the fault query screen in the form of light-on boards (such as Figure 5 ), and at the same time query the screen at the fault location (such as Image 6 ) shows that the screen where the fault device is located is the accident lighting scre...

Embodiment 3

[0033]When the device 3 in the DC panel (such as DC monitoring communication) fails, its fault data or switching value is collected by the DC monitoring unit. After the CPU in the DC monitoring unit judges that the data or switching value is a fault phenomenon, it can communicate through the RS232 / 485 communication interface. Upload the fault data to the programmable logic controller PLC. After analyzing the data, the PLC judges the location of the device 3 that caused the fault, controls the fault buzzer to sound an alarm, and uploads the data to the touch screen display through the RS232 / 485 interface at the same time : Firstly, "system failure" will be displayed on the main screen, (such as Figure 4 ), followed by displaying the specific fault content on the fault query screen in the form of light-on boards (such as Figure 5 ), and at the same time query the screen at the fault location (such as Image 6 ) shows that the screen where the faulty device is located is a DC ...

Abstract

The invention relates to a high-frequency switch DC power supply panel, in particular to a fault monitoring and warning device and fault monitoring and warning method of a DC panel. The method comprises the following steps that: when a device inside the DC panel goes wrong, a monitoring unit collects fault data or a switching value; when a CPU inside the monitoring unit judges that the data or the switching value indicates a fault phenomenon, the fault data is uploaded to a programmable controller through a communication interface; and the programmable controller judges the position of a device causing the fault through data analysis to control a fault warning device to send a warning signal, and uploads the data to a touch screen display through the communication interface.

Description

technical field [0001] The invention relates to a high-frequency switch DC power supply panel, in particular to a DC panel fault monitoring and alarm device and a fault monitoring and alarm method. Background technique [0002] As shown in Figure 1, it is the composition of the existing DC panel system. The DC screen system consists of two AC input parts, charging and control modules, voltage regulators, battery packs, output circuits and intelligent fault monitoring and alarm devices. [0003] Such as figure 2 As shown, it is the composition of the DC screen intelligent fault monitoring and alarm device. It is composed of main monitoring display, programmable logic controller (PLC), battery monitoring unit, DC monitoring unit, AC monitoring unit, insulation monitoring unit and module monitoring unit. Realize remote measurement, remote signaling, remote control, and remote adjustment for monitoring components. [0004] Such as image 3 As shown, it is the communication ...
