2) electric energy meter data acquisition
Can check meter day or timing acquisition time is gathered at interval, storage of electrical energy table data by the on-the-spot service terminal equipment of the electricity consumption of setting by the RS-485 communication interface, image data comprises: have/the reactive energy indicating value, have/information such as idle maximum demand and time of origin, power, voltage, electric current, electric energy meter parameter, electric energy meter state, and call together in main website and to send to main website when surveying, the electric energy meter data of on-the-spot service terminal equipment records of electricity consumption and demonstration should be consistent with the corresponding data that the electric energy meter that is connected shows.
Data processing module is realized in the following manner:
1) real-time and current data
2) historical day, month data
3) quality of power supply qualification rate statistics
Control module realizes in the following manner:
The closed-loop control of power definite value
Have the power the settled value curve setting of many covers and the control of temporarily rationing the power supply
Many cover power definite value series are used to adapt to the realization of the avoiding the peak hour of the multiple mode of user, factory day-off, line being stopped etc. planned ordered electric scheme.The priority of quadruplet power definite value series is 4,3,2,1 order.
Every in the present embodiment cover power the settled value curve is provided with 8 periods, and the period is accurate to minute, and each period can be provided with different power definite values.There are three types of (day, the moon, week) plans of establishment the time of implementation of every cover power the settled value curve, is provided with flexibly as required.
Main website issues the order of power control input to the on-the-spot service terminal equipment of electricity consumption, and power control drops into, and when power control input and not when protecting electricity condition, carries out the closed-loop control functions of overlapping a certain cover curve of power the settled value curves according to being provided with automatically more.The on-the-spot service terminal equipment of electricity consumption is monitored realtime power in the power control period, when power surpasses the value of setting (definite value * (1 ± unsteady coefficient %)) and continues for some time (can be provided with), producing power overdetermination value reports to the police, but enter the aural warning of one section setting-up time (minute to be unit), alarm time finishes to control corresponding controlled on-load switch by round sequentially-operating output relay.
It is following or dropped to security personnel's definite value to continue to drop to the value of setting at the appointed time as the on-the-spot service terminal monitoring of equipment of electricity consumption realtime power, produces power overdetermination system and recovers to report to the police, and stops to end the action of subsequent passes.The on-the-spot service terminal equipment of electricity consumption automatically performs in the process of overlapping the closed-loop control of power the settled value curve more and should show definite value, controlling object, execution result etc. on display screen.
After end of control period or period control are removed, allow the user to close because the period is controlled the trip switch that causes.The control of temporarily rationing the power supply:
Main website issues to ration the power supply to control to electricity consumption scene service terminal equipment temporarily and drops into order, issues simultaneously the coefficient k % that floats downward, average load calculating slippage time M (min) are set, and rations the power supply temporarily and controls effective time, the isoparametric order of minimum load;
After the on-the-spot service terminal equipment of electricity consumption received that the control of temporarily rationing the power supply drops into order, rationing the power supply when temporarily, control dropped into and not when protecting electricity condition, automatically perform power definite value closed-loop control function.According to the current definite value of calculation of parameter is set, when the on-the-spot service terminal monitoring of equipment of electricity consumption realtime power surpasses current definite value and continues for some time (this time can be provided with), but enter the aural warning of one section setting-up time (min of unit), alarm time finishes, by setting round action output relay, control controlled on-load switch, until realtime power under current definite value.
After the control of temporarily rationing the power supply was removed or controlled the period end, the on-the-spot service terminal equipment of electricity consumption allowed the user to close and controls the trip switch that causes because current power is floated downward.
The on-the-spot service terminal equipment of electricity consumption can be dropped into or be removed the function of its power definite value closed-loop control by a main website distant place, and on display screen show state.Power control is removed, and can cancel the tripping operation control that is caused by the closed-loop control of power definite value automatically, and on display screen show state.When the on-the-spot service terminal equipment of electricity consumption is in guarantor's electricity condition, do not carry out the closed-loop control of power definite value.
