The present embodiment provides a power control system 20, as shown in fig. 1, the power control system 20 is connected to a power module 40 through a switch module 30, and the connection manner is electrical connection. The power supply control system 20 includes: a control module 202, configured to determine whether the power module 40 meets a reset condition, and output a first control signal when the power module 40 meets the reset condition; the delay driving module 204 is configured to output a first switching signal for controlling the switch module 30 to be turned off according to the first control signal, and output a second switching signal for controlling the switch module 30 to be turned on after a set time.
First, the control module 202 determines whether the power module 40 meets a reset condition, and does not output the first control signal when the reset condition is not met, and outputs the first control signal when the reset condition is met. Then, the delay driving module 204 outputs a first switching signal for controlling the switching-off of the switching module 30 according to the first control signal, and outputs a second switching signal for controlling the switching-on of the switching module 30 after a set time, thereby implementing the automatic power-down reset of the power module. Compare and pull out total electricity and insert total electricity again in the manual work, safer, in time.
The first control signal may be set according to a trigger manner of the delay driver 204. If the triggering mode of the delay driving module 204 is high level triggering, the first control signal is a high level signal; and if the triggering mode of the delay driving module is low-level triggering, the first control signal is a low-level signal. In this embodiment, the delay driving module adopts a 555 timer, the monostable trigger of the 555 timer is a falling edge trigger, and an input pin of the 555 timer needs to be connected to a 5V default high-level input through a pull-up resistor, so that the low-level input can be triggered to work.
The first switching signal and the second switching signal may be set according to a driving method of the switching module 30. If the switch module 30 is turned off when a high signal is inputted, the first switch signal is a high signal, and the second switch signal is a low signal. If the switch module 30 is turned off when a low level signal is inputted, the first switch signal is a low level signal, and the second switch signal is a high level signal.
In an embodiment, when the electrical device connected to the power module 40 operates abnormally, the control module 202 outputs a second control signal for controlling the electrical device to reset; when the electric device is still abnormal after the electric device is reset, the control module 202 determines that the power module meets the reset condition.
Specifically, the control module 202 determines whether the communication with the electrical equipment is normal, and if the communication is normal, determines that the electrical equipment is working normally; and if the communication is abnormal, judging that the electric equipment works abnormally. When the electric equipment connected to the power module 40 works abnormally, the control module 202 outputs a second control signal for controlling the electric equipment to reset; when the control module 202 determines that the power consumption device still works abnormally after the power consumption device is reset, the control module 202 determines that the power module 40 meets the reset condition.
It is understood that, besides the communication abnormality determination of the electric device, other abnormality determination of the electric device may also be performed, such as output voltage, and the like, and is not limited in this embodiment.
When a plurality of electrical devices are abnormal at the same time, the control module 202 determines that the power module meets the reset condition and outputs a first control signal.
In one embodiment, the set time may be adjusted according to actual power down time requirements. The delay driving module is a 555 timer, the set time is adjusted by adjusting a distance pin and a Treshold pin of the 555 timer, and the set time T is approximately equal to 1.1RC.
In an embodiment, the control module 202 is further configured to output a third control signal for controlling the switch module 30 to remain on during a power-on process of the electrical device connected to the power module 40.
Considering that the control pin of the control module is directly connected to the input pin of the delay driving module, the result is that the electric equipment is continuously restarted. The main reason is that the input pin of the delay driving module is firstly changed to high in the power-on process, then a section of low level pulse (the retention time is about hundreds of us, and the delay driving module is triggered to work) is changed to high, and the process is continuously repeated, so that the switch module is continuously and repeatedly switched on and off. Therefore, in this embodiment, the control module outputs the third control signal for controlling the switch module to be kept on during the power-on process of the electric device connected to the power module, so as to ensure that the electric device is not powered off during the power-on process.
In one embodiment, as shown in fig. 2, the power control system 20 further includes: a signal processing module 206, configured to output a fourth control signal according to the first control signal and the third control signal; the delay driving module 204 drives the switch module 30 to be turned on or off according to the fourth control signal.
Specifically, as shown in fig. 3, the signal processing module 206 includes: a not circuit 206a, configured to not-gate the third control signal output by the control module 202; the or gate circuit 206b is configured to output a fourth control signal after the or gate processing on the third control signal after the not gate processing and the first control signal output by the control module 202.
And after the control module sends the dog feeding signal to the watchdog resetting chip, the watchdog resetting chip outputs a third control signal. When the supply voltage of the watchdog reset chip rises to 2.93V, the output keeps low level of 200ms, and meanwhile, no dog feeding signal is input, and the output keeps low level.
In one embodiment, as shown in fig. 4, the power control system 20 further includes: the level shifting module 208 is configured to perform level shifting on the fourth control signal output by the signal processing module 206, and input the level-shifted fourth control signal to the delay driving module 204.
In an embodiment, fig. 5 is a schematic diagram of the overall structure of the power control system 20. In this embodiment, the delay driving module is a 555 timer triggered by a low level.
In the power-on process of the electric equipment, because the control module 202 needs to be started from the kernel, the state of the first control signal output pin is indefinite, and the output may be a low level, a high level or a high resistance state, and because the watchdog reset chip outputs a low level before the watchdog feeding signal is input, the low level is inverted by the not-gate circuit 206a and then becomes a high level. The high level and the first control signal are input to the or gate circuit 206b, or the or gate circuit 206b always outputs the high level. Because the delay driving module 204 is triggered at a low level, it can be ensured that the delay driving module 204 is not triggered by mistake in the whole power-on process.
During the reset process of the power module 40, the control module 202 outputs the first control signal as a low level, outputs a high level through the or gate circuit 206b, and triggers the delay driving module 204 to operate after performing level conversion through the level conversion module 208. The delay driving module 204 outputs a high level pulse for a period of time, the pulse controls the switch module 30 to be turned off, when the power supply module 40 is powered off for a period of time T, the delay driving module 204 outputs a low level pulse, the switch module 30 is turned on, and the power supply module is reset.
