Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example one
The technical scheme provided by the embodiment of the invention is particularly applied to low-power-consumption wireless equipment, the equipment is low-power-consumption wireless Internet of things equipment, and the equipment can support one or more of wireless protocols such as WIFI, Zigbee, NB-loT, eMTC, Z-wave, LoRa, SigFox, RF (radio frequency), Bluetooth and the like. The low-power-consumption wireless equipment can be specifically installed on the intelligent door and used for detecting whether a person approaches the intelligent door; and may also be specifically configured in other application scenarios, which are not limited herein.
The technical solutions provided by the embodiments of the present invention are described in detail below.
Referring to fig. 1, a schematic flow chart of an infrared detection false triggering prevention method provided in an embodiment of the present invention is specifically applicable to a low power consumption wireless device, where the low power consumption wireless device includes a pyroelectric infrared sensor, and the infrared detection false triggering prevention method may include the following steps:
step S101, acquiring a sleep wake-up signal, and judging whether the sleep wake-up signal is a PIR trigger signal.
It will be appreciated that in order to ensure low power consumption of the device, a low power wireless device may need to enter a sleep state when not in an active state, and if a sleep wake-up signal is received, may enter a wake-up state and perform corresponding actions.
It should be noted that the sleep wake-up signal may include various types of signals, including, but not limited to, a PIR trigger signal, a key trigger signal, and a timing trigger signal.
And S102, when the sleep awakening signal is a PIR trigger signal, judging whether a human body moves in a PIR monitoring range or not according to the PIR trigger signal.
Specifically, when the sleep wake-up signal is the PIR trigger signal, whether a human body moves in the PIR monitoring range is judged according to the signal type of the PIR trigger signal. For example, the PIR trigger signal is a specific level signal, and when human body movement is preset, the trigger signal is a high level, otherwise, the trigger signal is a low level; at this time, when the PIR trigger signal is at a high level, the human body moves in the PIR monitoring area, otherwise, the human body does not move.
And step S103, judging whether the low-power wireless equipment is sending wireless messages or not when human body movement occurs.
And step S104, when the low-power wireless equipment sends the wireless message, clearing the PIR trigger signal.
Specifically, when human body movement is detected, whether the device is sending wireless messages or not is judged, and when the device is sending wireless messages, the PIR trigger signal can be cleared. While clearing the PIR trigger signal may specifically be accomplished by pulling a pin level signal low or high. When the human body movement is not detected, the sleep time can be cleared, and then whether the human body enters the sleep state or not is determined.
And S105, when the low-power wireless equipment does not send the wireless message, judging whether PIR triggering meets a preset normal triggering condition or not according to the dormancy time of the low-power wireless equipment.
It should be noted that the preset normal trigger condition is an empirical condition obtained through a lot of experiments, and is used for determining the influence of the device on the trigger signal from waking to sleeping. The preset normal trigger condition may specifically be that the sleep time is greater than a first preset threshold or equal to zero, that is, when the sleep time is greater than the first preset threshold or equal to zero, the PIR trigger is a normal trigger; otherwise, if the sleeping time is greater than zero and less than or equal to the first preset threshold, the PIR trigger is a false trigger.
The first preset threshold may be set according to actual conditions. Preferably, the first preset threshold may be specifically 500 ms.
And S106, when the PIR trigger does not accord with the preset normal trigger condition, clearing the PIR trigger signal.
Specifically, when the PIR trigger is a false trigger, then the PIR trigger signal may be cleared. And clearing the PIR trigger signal can be realized by pulling a level signal of a corresponding pin down or pulling a level signal of a corresponding pin up. And when the PIR trigger is a normal trigger, corresponding PIR operation may be performed, for example, reporting the PIR trigger signal to the monitoring platform, and then clearing the sleep time and clearing the PIR trigger signal.
In the embodiment, when the motion of a human body is detected through the received PIR trigger signal, whether the low-power wireless equipment sends a wireless message is judged, if so, the PIR trigger signal is a false touch signal, and the PIR trigger signal is cleared to prevent false triggering; when the low-power wireless equipment is determined not to send the wireless message, judging whether the sleeping time of the low-power wireless equipment meets a preset normal triggering condition or not so as to judge whether the low-power wireless equipment enters a sleeping state from a wake-up state or not, if not, determining that the PIR triggering signal is a false triggering signal, and clearing the PIR triggering signal. Therefore, the possibility of false triggering of the low-power-consumption wireless equipment is reduced, the reliability of the equipment is greatly improved, and the user experience is improved.
Example two
Through the technical scheme of the embodiment of the invention, the false triggering caused when the wireless equipment sends the wireless message or the equipment wakes up to sleep can be prevented. First, the hardware implementation of the PIR sensor shown in fig. 2 will be described. As shown in FIG. 2, U1 is a PIR sensor, specifically model E931.96B, which includes pins VDD, INT/DOC1, PIRIN, TEST, etc., and some necessary peripheral circuitry on the sensor periphery. E931.96B the sensor can detect the change of infrared ray intensity of human body radiation, and the change can be used as a standard for human movement. Generally, in the E931.96B monitoring area, if no human being appears or does not move, the signal intensity curve detected by E931.96B is almost flat, and when a human body appears or moves, the signal intensity curve fluctuates greatly, and according to the fluctuation characteristic, whether the human body moves or not can be judged.
In the research process, through a large amount of test and research work, the applicant finds that the power supply fluctuation of the VDD end can affect the change of the output level of a PIR _ INTDOC pin, so that false triggering and false detection are caused, the power supply fluctuation of the VDD end mainly occurs when the device sends a wireless signal and when the device wakes up to sleep, and based on the finding, the applicant shields the PIR triggering signal in the scene that the device sends a wireless message and the like, and prevents the false triggering and the false detection.
Referring to fig. 3, another schematic flow chart of an infrared detection false triggering prevention method according to an embodiment of the present invention is shown, where the method includes the following steps:
step S301, if receiving the sleep wake-up signal, judging whether the received sleep wake-up signal is a PIR trigger signal, if so, entering step S302, and if not, entering step S306.
Step S302, judging whether a human body moves in a PIR monitoring range or not according to the PIR trigger signal, if so, entering step S303, and if not, entering step S306 after clearing the sleep time.
Step S303, judging whether the low-power wireless device is sending wireless information, if not, entering step S305, if yes, clearing the PIR trigger signal, and entering step S306 after clearing the dormancy time.
Step S304, judging whether PIR triggering accords with a preset normal triggering condition or not according to the sleeping time of the low-power-consumption wireless equipment, and when the sleeping time of the low-power-consumption wireless equipment is larger than a first preset threshold value or equal to zero, the PIR triggering accords with the preset normal triggering condition, and entering step S305; when the sleep time of the low-power-consumption wireless device is greater than zero and less than or equal to a first preset threshold, the PIR trigger does not meet a preset normal trigger condition, the PIR trigger signal is cleared, the sleep time is cleared, and then the step S306 is executed.
The first preset threshold may be set according to actual conditions. Preferably, the first preset threshold may be specifically 500 ms. That is, when the sleep time is greater than 500ms or equal to 0ms, the process proceeds to step S305, and when the sleep time is greater than 0ms and less than or equal to 500ms, the process proceeds to step S306.
And S305, after PIR operation is executed according to the PIR trigger signal, clearing the PIR trigger signal and clearing the sleep time.
It can be understood that the low-power wireless internet of things devices all have monitoring platforms thereof, and the monitoring platforms can be, for example, intelligent terminals such as mobile phones and computers. Therefore, in some embodiments of the present invention, the performing the PIR operation according to the PIR trigger signal may specifically be: and uploading feedback information to a monitoring platform of the low-power-consumption wireless equipment according to the PIR trigger signal. That is, based on the PIR trigger signal, feedback to the monitoring platform accordingly may be made. For example, when the low-power wireless device is specifically arranged on the smart door, when the PIR sensor of the low-power wireless device detects that a person approaches, corresponding feedback information is uploaded to a mobile phone of a user so as to inform the user that the person approaches.
Step S306, judging whether the low-power wireless equipment meets the condition of entering the dormant state, and entering step S308 when the low-power wireless equipment meets the condition of entering the dormant state; when the low power consumption wireless device does not meet the condition for entering the sleep state, the process returns to step S301.
Because the low-power wireless equipment needs to enter the sleep state when not working, after the sleep time is cleared when no human body movement is detected, or after the PIR trigger signal is cleared and the sleep time is cleared, whether the low-power wireless equipment meets the condition of entering the sleep state or not can be judged, if yes, the low-power wireless equipment enters the sleep state and is subjected to sleep counting, and if not, the step S301 is returned, and whether the trigger signal exists or not is monitored continuously.
In some embodiments of the present invention, the specific process of determining whether the low power consumption wireless device meets the condition of entering the sleep state may be: judging whether the execution action corresponding to the dormancy awakening signal is finished or not; when the execution action corresponding to the dormancy wakeup signal is completed, the low-power wireless equipment meets the condition of entering the dormancy state; when the execution action corresponding to the sleep wake-up operation is not completed, the low power wireless device is not eligible to enter a sleep state.
It can be understood that, when the sleep wake-up signal is a key wake-up or a timing wake-up, the executed action is correspondingly an action corresponding to the wake-up operation. For example, when the timer is timed wake-up, the timed wake-up is the remaining time of the timer for resetting the device, and at this time, if the device has reset the timer, it is considered that the execution action corresponding to the timed wake-up is already completed, and it is in accordance with the condition of entering the sleep state. And when the sleeping wake-up signal is a PIR trigger signal, the execution action is to clear the PIR trigger signal or clear the PIR trigger signal after the PIR operation is executed, if the PIR trigger is determined to be false trigger, the PIR trigger signal is cleared, and after the clearing is finished, the execution action is considered to be finished and accords with the condition of entering the sleeping state.
Step S307, starting the sleep time count, and then entering the sleep state.
In the embodiment, when the motion of a human body is detected through the received PIR trigger signal, whether the low-power wireless equipment sends a wireless message is judged, if so, the PIR trigger signal is a false touch signal, and the PIR trigger signal is cleared to prevent false triggering; when the low-power wireless equipment is determined not to send the wireless message, judging whether the sleeping time of the low-power wireless equipment meets a preset normal triggering condition or not so as to judge whether the low-power wireless equipment enters a sleeping state from a wake-up state or not, if not, determining that the PIR triggering signal is a false triggering signal, and clearing the PIR triggering signal. Therefore, the possibility of false triggering of the low-power-consumption wireless equipment is reduced, the reliability of the equipment is greatly improved, and the user experience is improved
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
