MSP430F5438A single-chip microcomputers, which are sent to display module, to be shown；
B, MSP430F5438A single-chip microcomputers judge whether current time reaches the electrical equipment and start working by existing program
Time, if it is, MSP430F5438A single-chip microcomputers export high level signal, high level signal driving operational amplification circuit is led
Logical, relay coil obtains electric, contact adhesive, and electrical equipment, which is powered, starts working；Otherwise, continue waiting for；
B, when main insert row module controls the insert row module to realize the control of electrical equipment off-air time, specific steps bag
Include：
C, user sets the electrical equipment off-air time by input module, and the electrical equipment off-air time passes through
MSP430F5438A single-chip microcomputers, which are sent to display module, to be shown；
D, MSP430F5438A single-chip microcomputers judge whether current time reaches the electrical equipment and be stopped by existing program
Time, if it is, MSP430F5438A single-chip microcomputers export low level signal, low level signal driving operational amplification circuit is cut
Only, relay coil dead electricity, contact disconnect, and electrical equipment is powered and is stopped；Otherwise, continue waiting for.
5. the main insert row module of intelligent modules insert row as claimed in claim 1 or 2 controls the insert row module to carry out electric current
The method for detecting power on/off, it is characterised in that specific steps include：
(I) present current value of electrical equipment is read, and the present current value of electrical equipment is changed into standard voltage value, will be produced
Raw voltage signal transmits to MSP430F5438A single-chip microcomputers and is stored in memory module；
(II) step (I) is performed every time t, t span is 0<T≤10s, obtain one group of current value of electrical equipment
{ a1, a2 ... an }, wherein, n is positive integer, and n >=3, asks for maximum amax and minimum value in { a1, a2 ... an }
Amin, when any value in { a1, a2 ... an } is not less than the current value of user's setting, if in time T
Amin/amax is less than 10% always, then electrical equipment is in holding state, the power-off of single-chip microcomputer control relay, and elimination is treated
Machine power consumption, wherein, T span is T>60s；When maximum amax exceedes the current value of user's setting, single-chip microcomputer control
Relay powers off.
