Abstract
The invention belongs to the field of power supply control and particularly relates to single-chip microcomputer detection and control technology. A multi-way power supply controller is formed by connecting a voltage detection input unit, a plurality of current detection input units and a plurality of relay control output units through a central control unit. The central control unit can determine whether the corresponding output unit is off or not according to correlations of changes in input values of the current detection input units. By a control method, one high power load can be prevented from simultaneously powering multiple control-independent power supply lines.
Description
Technical field
The invention belongs to power supply control field, particularly one-chip computer current detecting, control technology.
Background technology
In order to prevent that the students' dormitory middle school student from using high-power heating to provide electrical appliance for oneself and causing fire, school is provided with a supply line at each dormitory and is connected with all electrical appliances at present; In each bar supply line a controller is installed, controller detects, controls each bar supply line, when high-power electric appliance uses, stops power supply.Adopted the method for restriction supply line general power in order to achieve the above object, and allowed to use the electrical appliance general power greater than a power that does not allow to use high-power electric appliance because living standard improves, the method can not be used; After adopting the method for differentiating unit interval internal power variation, because the user adopts progressively boosted voltage power supply, make the unit interval variable power little, the method can not be used; Adopt the method that the pure resistance linear load does not allow high-power linear load to use of differentiating at present; Because the user gives the power supply of pure resistance high power load with electric network source rectification, filtering, inversion, pressure regulation; Convert linear load to non-linear, that power progressively increases load, make this method can not limit the high power electrothermal device and use.But in order in dormitory, to allow to use heated type water dispenser (like power 400W), the controller that uses at present can allow the resistive load of a certain power (like 400W) to use; But the student can use and the electric heater of heating water fountain with power.Some schools hope that the power supply base of students' dormitory at night in summer can only allow to use the student to provide electric fan for oneself, and other electrical equipment can not use, and does not have implementation method at present.
Summary of the invention
The present invention seeks to prevent to use in the students' dormitory high-power electric appliance; Night in summer the students' dormitory power supply base only allow to use the student to provide electric fan for oneself.
Method of the present invention is that the multiple-way supply controller is taked following operating conditions.
Some output unit timesharing are connected.
The individual current detecting unit input value of supply line continuously of N increases simultaneously and equates that corresponding output unit breaks off.
N the continuously current detecting unit input value of supply line increases simultaneously and is unequal, but N input value increment summation be greater than definite value, the disconnection of the output unit of correspondence.
N continuously current detecting unit input value timesharing in the unit interval of supply line increases and equates and greater than definite value, corresponding output unit disconnection.
N continuously current detecting unit input value timesharing in the unit interval of supply line increases, and a current detecting unit input value causes the variation of other current detecting unit input value, corresponding output unit disconnection when increasing.
The power intermittently current detecting unit input value of varying duty supply line does not change by setting rule, and corresponding output unit breaks off.
The present invention can prevent supply line's power supply that a high power load is independently controlled with multichannel simultaneously.
Embodiment
Embodiment 1, and single-chip microcomputer of the present invention is the control method of central control unit multiple-way supply controller.The multiple-way supply controller is made up of central control unit connection voltage detecting input block, several current detecting input blocks, several relays control output units.
Each output terminal of multiple-way supply controller connects a supply line and only gives certain loads power supply in the students' dormitory: independently-powered line powering of each student's notebook computer; Independently-powered line powering of each student's desk lamp and electric fan; Independently-powered line powering of indoor roof lamp of every dormitory; But independently-powered line powering of the heating water fountain of every dormitory; Independently-powered line powering of the water heater of every dormitory.
But the intermittently variation pattern work of power according to certain rules of heating water fountain and water heater, but with heating water fountain and water heater and the disconnection of its supply line; When supply line connected the continuous working load corresponding with its power, the multiple-way supply controller stopped its power supply.
Central control unit judges when having only the electric fan work by the work of natural wind state night in summer according to time, indoor temperature and keeps power supply that other load is used and stopped power supply; Promptly have only power to be not more than electric fan rated power, could use by the power varying duty at intermittence of setting rule (cycle and dutycycle) variation.
The product of several current detecting input block input values and voltage detecting input block input value is during greater than definite value, breaks off with its output unit of relay control one to one stopping to supply power to electrical appliance; Limit the supply load of each bar supply line, prevent to use high-power electric appliance on the circuit of continuous working electric at some.
Each output terminal of multiple-way supply controller is connected with the same phase line of electric network source.For the supply line's power supply that prevents that the high power load from independently controlling with multichannel simultaneously, the multiple-way supply controller adopts following operation:
The corresponding output terminal timesharing of some output unit controls is connected with electrical network.
The individual current detecting input block input value of supply line continuously of N increases simultaneously and equates, corresponding output unit breaks off and stops powering load.
N the continuously current detecting input block input value of supply line increases simultaneously and is unequal, but N input value increment summation be greater than definite value, the output unit of correspondence disconnection stopping powering load.
N continuously current detecting unit input value timesharing in the unit interval of supply line increases and is equal and greater than definite value.Corresponding output unit breaks off and stops powering load.
N current detecting unit input value timesharing increase in the unit interval of supply line continuously; And a current detecting unit input value causes the variation of other current detecting unit input value when increasing, corresponding output unit breaks off and stops powering load.
