Make, charging pile display screen can show that the data such as charge volume, expense, charging time, existing charging pile control system work are inadequate
Stablize, and scalability is poor.
Utility model content
A kind of linear electrical isolation circuit that in order to solve the above problems, the utility model proposes, circuit are set using modularization
Meter, work are more stablized；Versatility is good；And scalability is good.
The utility model discloses a kind of linear electrical isolation circuit, including power isolation module, linear electrical isolation electricity
The high-pressure side on road is connected to power isolation module by protective cover, division module, amplifier processing module one step by step, the power supply every
It is spread out of step by step by amplifier processing module two, sampling module again from the feedback signal that module provides, the power isolation module is set
There is the characteristics of internal electric source and external power supply, this structure to be, linear electrical isolation circuit can realize that the level of 12V-12V is defeated
Go out.
Further, the internal electric source is made of TPV1212SARP chips and its peripheral circuit, realizes power supply power supply.
Further, it is equipped with light-coupled isolation HCNR201 chips in the external power supply, converts the electrical signal to light letter
Number, the linear isolation between realizing electrically.
Further, the amplifier processing module one constitutes circuit by LMV358.
The characteristics of the utility model and advantageous effect：Circuit uses modularized design, work more to stablize；Versatility
It is good；And scalability is good, circuit realizes the output of 12V-12V level, by external high pressure level conversion at optical signal, realize it is electrical it
Between linear isolation.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Specific implementation mode
Below by conjunction with attached drawing, the utility model will be further described.
A kind of linear electrical isolation circuit as shown in Figure 1, including power isolation module 1, linear electrical isolation circuit
