In conclusion the present invention has the following advantages：The positive anjd does not need circuit interlocking
Realize that the monophase machine positive and negative rotation control of safety, wiring are simple and of low cost.
Description of the drawings
Fig. 1 is the wiring diagram of the present invention.
Specific implementation mode
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
Embodiment is only used for explaining the present invention, is not intended to limit the scope of the present invention..
According to Fig. 1, the present invention provides a kind of operation sides of the positive anjd with hardware self-locking
Method, steps are as follows：
A, J3 interfaces short circuit, Vcc access positive pole, and COM connection positive and negative rotations control signal common end, and COM1, COM2 connection are single
Phase motor common end, CW connection monophase machine forward direction operation ends, CCW connection monophase machine inverted runnings end；In X1, X2 without letter
Number input when circuit be in off state, motor is in halted state；When X1 has signal, X2 no signals, 1 foot of U1, the 1 of U2
Foot is in low level state, and 2 feet of U1,2 feet of U2 are in high level state, and 3 feet of Q2 are connected with 2 feet, electric current through Vcc, R7,
1 foot and 2 feet of R9, U5,3 feet of D2, Q2 and 2 feet are to 1 foot of U1,1 foot of U2, at this point, D2 is lighted, U5 conductings, 4 feet of U5 with
6 jiaos of conductings, monophase machine carry out positive operation；When X1 no signals, X2 have signal, 1 foot of U3,1 foot of U4 are in low level
State, 2 feet of U3,2 feet of U4 are in high level state, and 3 feet of Q1 are connected with 2 feet, 1 foot of the electric current through Vcc, R8, R10, U6
