Description
Technical Field

Background
The power-off switch is widely used in the electronic industry, is only used for switching on and off power at first, and along with the rise and development of intelligent hardware, the power-off switch is endowed with more and more using methods and purposes while being compatible with traditional functions. For example, the color temperature or brightness of the bulb or the light mode is switched by the power-off switch; and the product is restored to factory settings or enters a distribution network state and the like by the continuous triggering times of the switch.
At present, a power-off switch on the market has two implementation modes, one mode is that a product is powered on, and a Flash record is written into a memory once when software starts to run; the other is that the product works normally, and the Flash record is written once when the software detects that the product is powered off in the running process. And each time the computer is electrified, different functions are executed or one state is triggered by reading the record in the Flash. The two modes have requirements on the charging and discharging time of the product hardware driving power supply, and have some defects: in the first mode, if the driving power supply discharges slowly, when the voltage does not drop below the starting voltage of the MCU, the MCU is powered on again, the MCU still runs normally, the running cannot be restarted, and Flash records cannot be written in. In the second mode, if the driving power supply discharges quickly, the voltage drops below the MCU working voltage instantly, the software does not detect the power failure, or the MCU stops working when the power failure trigger operation is not written into the Flash record. From the above analysis, it can be known that the compatibility, reliability and consistency of the current scheme on the market are not good, so that the switch power-off triggering times cannot be accurately detected.

Fig. 1 is a flowchart of a method for detecting a switch outage according to an embodiment, where, as shown in fig. 1, the method for detecting a switch outage includes steps 110 to 140; wherein:
and step 110, receiving a switch power-off detection signal, wherein the switch power-off detection signal is a square wave signal obtained by rectifying and depressurizing the alternating current.
And step 120, acquiring the level of the switch power-off detection signal.
Switch outage detected signal can be high-low level, is the low level when adopting the outage in this application, is the 50HZ square wave during normal power supply. It is understood that the switch de-energizing detection signal can be a square wave of other frequencies.
In addition, the switch power-off detection signal in the application is a square wave signal obtained after rectification and voltage reduction processing is carried out on alternating current. The hardware circuit for obtaining the switch power-off detection signal is shown in fig. 2, that is, one more line is added to the original driving power supply, and the switch power-off detection signal obtained after the AC power supply is rectified and stepped down is input to a single chip or a processor for normal IO.
The self-reset switch is taken as an example for explanation, the self-reset normally-closed switch is closed at ordinary times, namely, the product is powered on at ordinary times, when the self-reset normally-closed switch is pressed down, the product can cut off the power supply of the power supply, the switch power-off detection signal immediately becomes low level, and at the moment, the singlechip, the processor or the Internet of things module immediately detects the switch power-off to execute related actions. It will be appreciated that the solution in the present application also supports other types of switches and is not limited to use only for self-resetting switches.
When the switch power-off detection signal is detected to be at a low level and the duration of the low level reaches a preset duration, it indicates that the user triggers the power-off action. When the power-off detection signal is detected to be at a high level, the user may not trigger the power-off action; possibly, the user does the power-off action, but the MCU is not really powered off and is powered on again; or the user does power-off operation and the MCU is powered on and restarted; it may also be that without actually powering down, it is powered up again. Therefore, it is not accurate to determine whether the user triggers the switch to power off according to the MCU power off condition. If the driving power supply discharges slowly, when the voltage does not drop below the starting voltage of the MCU, the MCU is powered on again, the MCU still runs normally and does not restart running, and Flash records cannot be written in, so that the omission of power-off triggering times is caused. If the driving power supply discharges quickly, the voltage drops below the MCU working voltage instantly, the MCU stops working when the software does not detect power failure or the Flash record is not written, and the omission of the power failure triggering times can be caused.
In this application, according to the level height of switch outage detected signal, set up outage sign and switch state and change the sign. The method comprises the following specific steps:
if the switch power-off detection signal is at a low level, judging whether the continuous low-level time is longer than a first preset time, and if so, setting a power-off flag to be a second preset value;
if the switch power-off detection signal is at a high level, judging whether the power-off mark is a second preset value;
if the power-off mark is the second preset value, setting the power-off mark as the first preset value, setting the switch state change mark as the fourth preset value, and adding 1 to the power-off triggering times;
and if the power-off mark is the first preset value, judging whether the switch state change mark is a fourth preset value, if so, setting the switch state change mark to be a third preset value, and adding 1 to the power-off triggering times.
In this embodiment, the first preset value and the third preset value are 0, and the second preset value and the fourth preset value are 1.
Preferably, whether the switch power-off detection signal is a square wave is detected firstly, and the square wave detection mode is as follows: and detecting whether the switch power-off detection signal has a high level or a low level, and if the current detected signal is the high level and the last detected signal is the low level, determining that the signal is a square wave signal. After it is determined that the received square wave is received, the subsequent judgment is started. Specifically, if the switch power-off detection signal is detected to be at a low level, whether the duration of the low level is longer than 200 milliseconds is continuously judged, and if so, the power-off flag is set to be 1.
If the switch power-off detection signal is detected to be high level, two judgments are available: one is to detect whether the power-off flag is set to 1, if the power-off flag is set to 1, it indicates that the user has done power-off operation, but the MCU is powered on again after not being really powered off, at this time, the power-off flag is cleared to 0, and the switch state change flag 1 is set; and secondly, if the power failure flag is 0, judging whether the switch state flag is set to be 1 or not, if the power failure flag is set to be 1, indicating that the user does power failure action, wherein the MCU may be powered on and restarted or powered on again without real power failure, clearing the switch state change flag to be 0 at the moment, starting switch state change timing, and adding 1 to the power failure triggering frequency.
Under the condition that the driving power supply discharges quickly, the voltage drops below the MCU working voltage instantly, the software does not detect the power failure, or the Flash record is not written in, the MCU stops working, and the power failure triggering times are missed.
When the intelligent device is powered on, the power-off triggering times are increased by 1 so as to compensate the condition that the last power-off triggering software cannot record the power-off triggering times caused by the last time and the power-off triggering times are missed.
Compared with the prior art, the switch power-off detection method comprises the steps of receiving a switch power-off detection signal, wherein the switch power-off detection signal is a square wave signal obtained by rectifying and reducing voltage of alternating current; acquiring the level of a switch power-off detection signal; setting a power-off mark and a switch state change mark according to the level of the switch power-off detection signal; the power-off mark is used for indicating whether a user triggers power-off action, and the switch state change mark is used for indicating the increase of the power-off triggering times; when the intelligent device is powered on, the power-off mark is set to be a first preset value, the switch state change mark is set to be a fourth preset value, and the power-off triggering frequency is increased by 1. According to the method, the power-off action triggered by the user is recorded through the power-off mark, if the MCU is detected not to be powered off at present, whether the power-off action is triggered by the user is judged according to the power-off mark recorded last time, and the switch state change mark is set, so that the problem that power-off triggering times are missed due to slow discharge of the driving power supply can be solved. In addition, aiming at the problem that the power-off triggering times are missed due to the fact that the driving power supply discharges soon, when the intelligent device is powered on, the power-off triggering times are increased by 1 so as to compensate the situation that the last power-off triggering software cannot record the missed power-off triggering times caused by the fact. The switch power-off triggering times are judged by the level height of the switch power-off detection signal and the dual judgment of the power-off mark and the switch state change mark, so that the accuracy of power-off detection is improved, and the method can well and accurately and quickly detect the power-off of the switch no matter whether the driving power supply discharges slowly or discharges quickly or quickly.
In some embodiments, the switch power-off detection method further comprises: and acquiring the power-off triggering times, and controlling the working state of the intelligent equipment according to the power-off triggering times.
The intelligent device in this application can be door and window sensor, intelligent lock, intelligent doorbell, intelligent camera, intelligent lamps and lanterns, intelligent air conditioner or other intelligent house equipment to can receive the control command that intelligent house controlling means issued and carry out corresponding action. The control device may be a switch, and the control instruction may be the number of times of triggering the switch. Different trigger times correspond to different modes of different intelligent devices. In this embodiment, the intelligent device is taken as an example to explain, for example, if a user continuously triggers the switch three times, the color temperature of the bulb is switched to the first color temperature; if the user triggers the switch for four times continuously, the light mode is switched to be the first mode; and if the user triggers the switch for five times continuously, the intelligent lamp is restored to factory settings, and the like. It should be noted that the number of times of switch triggering and the working state of the matched intelligent device may be preset and stored in the memory, and when the switch power-off triggering is detected, the stored working state corresponding to the intelligent device is queried and the intelligent device is controlled to execute the operation.
Because the switch outage in this application detects fast and accurately, consequently, control smart machine is quick accurate more, the chaotic problem of control can not appear to user experience has been promoted.
In some embodiments, the first preset duration is greater than or equal to 2 cycles of the square wave signal.
Referring to fig. 4, each period of the square wave signal includes a high level and a low level. If the switch power-off detection signal is a 50HZ square wave signal, 20 milliseconds 1 period, 1 period has high and low levels, and 200 milliseconds has 10 periods of square wave signals. It can be understood that 200 milliseconds can be properly adjusted, and theoretically, as long as the continuous low level is ensured within more than 2 cycles, it can be determined that the user has performed the power-off triggering action.
In some embodiments, the switch power-off detection method further comprises: recording the duration of the change of the switch state; and if the on-off state change duration is longer than a second preset duration, clearing the previous power-off triggering times and the on-off state change duration.
The second preset time length can be 5 seconds, 6 seconds or 7 seconds, and a user can set the specific time length according to actual conditions or habits. The present embodiment takes the second preset time period as 5 seconds as an example for explanation. When the on-off state change duration is longer than 5 seconds, namely the on-off state is not changed for more than 5 seconds, the previous continuous pressing times are cleared and stored in the memory, so that misoperation of a user is avoided.
In order to better describe the effectiveness of the switch power-off detection method provided by the present application, the following describes the program operation flow in four situations, as shown in fig. 3. It can be seen from the flow that no matter the driving power supply discharges slowly, discharges fast, or fast and slow, the switch power-off detection method provided by the application can be well compatible with various situations, and the switch power-off can be detected accurately and fast.
The first situation is as follows: first power up (MCU power up restart), refer to fig. 4.

Then, the power-off flag is cleared to 0, and the switch state change flag is set to 1, and a power-off detection cycle is entered. And judging whether the switch state change flag is set to be 1 or not, if so, indicating that the user does power-off action, the MCU may be powered on and restarted or not and powered on again, clearing the switch state change flag to be 0 at the moment, starting switch state change timing, adding 1 to the number of continuous pressing times, setting the equipment state and storing the equipment state in Flash, and then executing the A related function module which can be understood as the working state of the intelligent equipment corresponding to the power-off times of the switch.
