It is that central controlled lock is powered that parallel operation remains to export a road voltage；The advantage of this scheme is that system is simple and convenient, low cost;Shortcoming is when whole
When the total emergency stop switch of car is closed, DC transducer cannot export and cause central controlled lock disabler；Effective to make central controlled lock function, need
Make the total emergency switch of car load be constantly in open mode, charged can there is certain potential safety hazard, in addition because car load main power is normal
Because central control lock controller itself exists certain power consumption, the most so may result in the total accumulator feeding of car load, overdischarge；
2, DC transducer still exports for single channel, and the accumulator increasing by one piece of low capacity is that central controlled lock function is powered, the total jerk of car load
Switch also has power supply to maintain central controlled lock work when cutting out, after opening ignition switch, DC transducer can be the charging of little accumulator；This
Scheme advantage be car load total emergency stop switch when closing central controlled lock function still effective, even if car load place for a long time be also not result in whole
The total accumulator feeding of car.Shortcoming is for be powered because DC transducer is also required to be other electrical equipments of car load, and output voltage should not surpass
Cross electrical part rated voltage too much, therefore cannot ensure as the little accumulator of central controlled lock fully charged.
It is substantially on small-sized electric money carriage market at present and takes both the above mode, because above two scheme is all deposited
In corresponding shortcoming thus be likely to result in corresponding problem.
Summary of the invention
