Description of drawings
Fig. 1 is the background technology example schematic;
Fig. 2 is a schematic diagram 1 of the present invention;
Fig. 3 is a schematic diagram 2 of the present invention.
Specific embodiment
The present invention is described in detail below with reference to accompanying drawing.
As shown in Figure 2, K2 is the twin coil magnetic latching relay, when reverse connection of accumulator, just has electric current and flow in the reversal connection warning device, and electric current arrives alarm H1 through V7, R1, and this moment, alarm can send warning, and prompting user storage battery is by reversal connection.When reverse connection of accumulator, no matter which kind of state K2 is in, because the existence of V1 and V2 does not have electric current to enter control unit, does not have electricity on the coil of K1, and K1 is failure to actuate, so KM1 also is failure to actuate, the voltage on the storage battery can not be introduced into the band loading system.
When accumulator positive connects, electric current enters control unit through V1,16 pin and 15 pin are control ends of K2, this moment, 16 pin had low level to trigger, the normally opened contact closure of K2, and the coil of power relay K1 powers on, the K1 action, its normally opened contact closure, D.C. contactor KM1 action this moment, the voltage on the storage battery is access in the band loading system.
In addition, as shown, parallel diode V4 and diode V5 respectively between the positive pole of two groups of coils of magnetic latching relay and negative pole, when when magnetic latching relay sends cut-off signals, V4 and V5 can discharge magnetic
The inverse electromotive force that produces on two groups of coils of latching relay.And also be parallel with a diode V3 between the positive pole of power relay coil and negative pole, when power relay moved, V3 can discharge the inverse electromotive force that produces on the power relay coil.
As shown in Figure 3, the voltage on the storage battery is introduced in the different band loading systems, in actual storage battery power supply process, can work long hours in order to guarantee some important load, need selectively power to the band loading system.When needs cut off the battery feed of some band loading system, 15 pin at the control power supply K2 that links to each other with this band loading system have the low level triggering, the normally opened contact of K2 is opened, the coil blackout of power relay K1, voltage on the storage battery just can not insert the band loading system by KM1 at this moment, realize storage battery is inserted the control of band loading system.
From the above; the present invention is simple in structure; the warning of reverse connection of accumulator and the control that loading system is with in access to storage battery have been realized; and because 15 pin of K2 and 16 pin and microprocessor link together; in the time will changing the protection voltage setting value of storage battery; be to realize that by the set point that changes in the microprocessor its control precision height has very strong practical value.
More than control system that accumulator for communication power supply provided by the present invention is inserted be described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above example just is used for helping to understand method of the present invention and core concept; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, the content of this specification should not be construed as limitation of the present invention.
