Overview of the platform system

The platform can realizeredl-time online monitoring of mobileAPP and background on PC;Can remote real-time monitoing through the lighning count liohningprotection device failure status,the SPD,such as temperature,line open alarm information,don't need to

travel long distances to the on-sie inspecion to be ableto grasp of the SPD real-time running state,the SPDs qging degradation is abnomal triping daomage,such as lightning ocuring can receive imely wamning,can timely for

equipment maintenance,to prevent undetection or fail to replace the loss caused by surge protector.

Surge protector set surge protection function and smart intelligent acquisition hardware at an organic whole,notonly have the functions of lightning surge

protection,surge protector itself will also be able to realize the statemonitor,including:the SPD degradation condition monitoring and the SPD false

grounding or monitoring,the SPDlightning number record,the SPD internal temperature monitoring,front open or back-up protector

power-on statemonitoring,abnormal state live sound and light alarm;

Configuration standard RS485 bus interface data communication,can choose RS485 private protocol or standardMODBUS protocol,can also be

customized according to customer demand private 485 protocol.RS485 privateprotocol can be used with our company's supporting monitoring software,

easy to network,easy to monitor,productstatus abnormal timely and effective early warning,historical data records form a log,easy to query and trace,

canbe exported to EXCEL,convenient for statistical analysis and printing.

The standard MODBUS protocol can be connected to other monitoring systems without complicated programming.
