To achieve these goals, the technical solution adopted in the present invention is: in the design process of car load circuit, the normal power supply that influences each current consumer of quiescent current is concentrated in the total loop, and design increases the disconnection of a handled easily and the main supply switch of recovery in this total loop.Specifically, collect each electric component information that car load influence quiescent current, during design electrical equipment box the electric power loop of those functions that need shield concentrated to hang under the general supply switch of increase by one handled easily in the loop of general supply.When the commodity car in entrucking or Before Loading, with this switch opens in the electrical equipment box, when vehicle arrives the destination again by the staff with this switch closure, recover each electric component function of conductively-closed.
Concrete technical scheme is as follows:
A kind of quiescent current control circuit, it is used for the multiple-purpose electric appliance system, comprises a total loop and a main supply switch, the normal power supply of each current consumer in this total loop central system, this main supply switch is controlled the switch of this total loop.Each current consumer is the current consumer that influences quiescent current in the system in the described system.The main supply switch of described total loop is located in the electrical equipment box.Described switch is a plug-in unit, the switch of pulling up and insert the control total loop of this plug-in unit.
A kind of car load circuit comprises a quiescent current control circuit, and this quiescent current control circuit has a total loop, and this total loop is concentrated the normal power supply of each current consumer in the car load, and other is provided with the switch that a main supply switch is controlled this total loop.Each current consumer is for influencing vehicle drive and security function in the described car load, and influences each electric component of quiescent current.Described switch is a plug-in unit, and the electrical equipment box of car load circuit will need the electric power loop of the function that shields to concentrate to hang under the general supply, be provided with a plug-in unit in the loop of this general supply, and this plug-in unit is located in the electrical equipment box, and it pulls up or insert the switch of control general supply.
A kind of quiescent current control method of car load in the design process of car load circuit, concentrates on the normal power supply of each current consumer in the total loop, and a main supply switch is set in this total loop, controls the switch of this total loop.Specifically may further comprise the steps:
1) collects each electric component information of car load;
2) electric power loop of each electric component is concentrated hung under the general supply;
3) in the loop of general supply, increase by a switch;
When 4) needing, with this switch opens in the electrical equipment box;
5) after needs are removed,, recover each electric component function of conductively-closed with this switch closure.
Electric component in the step 1) is not for influencing vehicle drive and security function, and car load influences the electric component of quiescent current.
To need the electric power loop of the function that shields to concentrate during step 2) further for design electrical equipment box hangs under the general supply.
Step 4) and 5) needs described in are respectively vehicle before entrucking or shipment and when vehicle arrives the destination.
Compare with present prior art, beneficial effect of the present invention is embodied in: in the design process of car load circuit, the normal power supply that influences each current consumer of quiescent current is concentrated in the total loop, and design increases the disconnection of a handled easily and the main supply switch of recovery in this total loop; Design is simple, realizes easily, and is with low cost, easy to operate.
