Some possible embodiments of the present application are described in more detail below with reference to table 1.
In table 1, a denotes a first switching signal; b represents a second switching signal; c represents a sensing signal; d represents a field programmable gate array control signal; PS _ ON # represents a power-ON signal; e and f are cylinder control signals, wherein e represents the ascending of the cylinder, and f represents the descending of the cylinder; g and h are both power-on control signals, g represents power-on, and h represents power-off.
Table 1 state control truth table
As can be seen from table 1, the PS _ ON # signal is normally high, and when the cylinder has moved to the predetermined position and the PS _ ON # signal is low, the switch control circuit 1 is powered ON.
Since the power normal indication signal is generally opposite to the PS _ ON # signal, when the PS _ ON # signal is low, the power normal indication signal should be high, which means that the power supply is working normally at this time, and can be powered ON.
In the initial state, the first switching signal and the second switching signal are both at a low level (a and b are both 0), and the logic control signal is at a low level (d is 0).
When the first switching signal and the second switching signal are switched to a high level (a and b are both 1) together, the first input terminal of the second and gate 132 is connected to the high level, and at this time, the power supply normal indication signal is at the low level, the second input terminal of the second and gate 132 is connected to the high level, and at this time, the latch control signal connected to the control terminal of the latch 135 is at the high level, and the output terminal state of the latch 135 is consistent with the data terminal thereof, so as to control the cylinder to rise (e is 1, f is 0).
When the cylinder moves to a preset position, the sensing signal changes from a low level to a high level (c changes from 0 to 1); meanwhile, the power supply normal indication signal changes from low level to high level (the PS _ ON # signal changes from 1 to 0), then the second input terminal of the second and gate 132 is switched into low level at this time, the latch control signal switched into the control terminal of the latch 135 is at low level at this time, the state of the data terminal of the latch 135 at this moment is latched to the output terminal, the e and f states are not changed, and the switch control circuit 1 is powered ON.
Referring to fig. 2, the present application further provides a switch control system according to some embodiments, which may include the switch control circuit 1 provided in any of the foregoing embodiments, a switch 2 and a sensing device 3.
Specifically, the switch 2 may be connected to the switch signal obtaining module 11, and configured to send a switch signal; the sensing device 3 may be connected to the sensing signal obtaining module 12 for sending out the sensing signal.
The switch control system provided by the above embodiments includes the switch control circuit 1 in some of the foregoing embodiments, so that the technical effects that the switch control circuit 1 can achieve can be achieved by the switch control system, and the details are not described here.
