Specific embodiment
Present invention is further described in detail with reference to the accompanying drawings of the specification.
The present invention is a kind of card insert type power output circuit board that can be individually replaced, including muti-piece power output circuit plate
Component and one piece of main circuit board component, every piece of power output circuit board group part is by externally exporting curved formula electric connector 1, power output
Circuit board 2 and internal curved formula electric connector 3 form, and main circuit board component is made of main circuit board 4 and busbar 5；Such as Fig. 1 institute
Show.
It externally exports curved formula electric connector 1 and internal curved formula electric connector 3 is installed on 2 both ends of power output circuit plate, it is right
The outer curved formula electric connector 1 of output is output to the outside power electricity, and internal curved formula electric connector 3 is for connecting power output circuit plate 2
With main circuit board 4.
As shown in Fig. 2, main circuit board 4 connects each power output circuit board group part by CAN communication circuit, external unit passes through
Busbar 5 is electric to card insert type power output circuit input power.
As shown in figure 3, having CPU control module, communication interface chip, driving chip on every block of power output circuit plate 2
And power device, CPU control module connect 5 power amplifier board Address Recognition signals；CPU control module connecting communication interface chip,
It is communicated with main circuit board 4；CPU control module connects driving chip, and driving chip connects power device.
On main circuit board 4 by+3.3V power supply be card insert type power output circuit power,
Power output circuit board group part on card insert type power output circuit is 1-32 block.
Foregoing circuit working principle are as follows: when circuit works, external power electric current accesses main circuit board, power by busbar
Output circuit plate is connected by internal curved formula electric connector with main circuit board, and external power electric current passes through main circuit board ingoing power
Output circuit plate input port, the communication data that power output circuit plate is sent according to main circuit board, control power device conducting
And disconnection, realize Cell and Time Distribution heating.
When circuit works, when CPU receives that external temperature is low to need heating information by communication interface chip, CPU is controlled
Driving chip output processed effectively control signal, the signal control power device conducting, externally export electric current, realize heating function；
When CPU, which receives external temperature by communication interface chip, does not properly need heating information, CPU controls driving chip and exports nothing
Effect control signal, power device cut-off do not export electric current externally, and heating function is closed.
