Accompanying drawing 1 is a system of the present utility model pie graph.
Accompanying drawing 2 is communication link figure of the present utility model.
Accompanying drawing 3 is the utility model embodiment schematic flow sheets.
Embodiment
As Fig. 1, Fig. 2, shown in, distribution type electric energy quality remote monitoring record wave system turnkey is drawn together some qualities of power supply monitoring device on the spot, Ethernet backstage and a public remote data center of some and matched with devices, described monitoring device on the spot is made of CPU card, communication management plug-in unit and GPRS module, and described monitoring record wave system system has two communication links.Link one: data are sent to the communication management plug-in unit by CPU card through the CAN net, are sent to the GPRS communication module by 485 again, are sent to remote data center via the GPRS wireless network at last.The baud rate of CAN net is 115200bps, and 485 baud rate is 9600bps; Link two: data are sent to the communication management plug-in unit by CPU card through the CAN net, are sent to the Ethernet backstage by Ethernet again.
Referring to Fig. 3, the sample frequency of its device is 6400Hz, and the utilization fast algorithm detects voltage in real time, in case voltage reaches the voltage dip threshold value or voltage rises threshold value temporarily, device starts the record wave energy in 1ms.In order to reduce the data volume of wall scroll record, increase the record total amount, the record wave frequency is for dividing the sample frequency of several times.
The input signal of device is 3 phase system voltages, 3 phase load voltages and 3 phase system electric currents.Device is calculating voltage effective value, current effective value, 0 ~ 17 voltage harmonic, 0 ~ 17 primary current harmonic wave, active power, reactive power, applied power, power factor, analog quantitys such as voltage THD, electric current THD in real time, and can regularly remote data center will be delivered on the analog data according to the time of setting.
