Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples. The method comprises the following specific steps:
detailed description of the invention
As shown in fig. 1, the safety self-inspection method of the UV lamp comprises the following steps:
s1: preparing materials, namely preparing a UV lamp, and an MCU (microprogrammed control unit), a key switch, an alarm module and a microwave induction module which are used for controlling the UV lamp;
s2: the method comprises the following steps that (1) detection is carried out for the first time, the microwave induction module outputs a high-level pulse when the microwave induction module is electrified for the first time, if the MCU of the UV lamp receives a high level, the microwave induction module does not fail, the UV lamp can be started, otherwise, the microwave induction module fails, the UV lamp cannot be started, and the alarm module needs self-checking alarm at the moment;
s3: the first detection in the step S2 is that, if the MCU of the UV lamp receives a high level, then if the key switch is manually turned on, the UV lamp is turned on, and during the turning on of the key switch, if the MCU of the UV lamp receives a high level, the microwave sensing module is not deactivated, the UV lamp can be turned on, otherwise, the microwave sensing module is deactivated, the UV lamp cannot be turned on, and the alarm module needs self-checking and alarming at this time; the step S3 is designed mainly in consideration of the fact that the keys need to be operated by hands, that is, the human body is close to the UV lamp, the microwave is sensed, that is, the microwave outputs a high level, and this point further determines whether the microwave module has a sensing effect, and if there is no high level during the key pressing, it indicates that the microwave module is out of sensing.
S4: delaying protection, namely after step S3, during the period of manually turning on the key switch, if the MCU of the UV lamp receives a high level, controlling the UV lamp to turn on after delaying T (T is more than 0) time by the MCU; this step S4 is designed mainly considering that the person leaves the irradiation area of the UV lamp, and the delay time T may be set according to the size of the irradiation area range and the speed at which the person moves.
S5: through step S4, in the T period of the delay protection, if the MCU of the UV lamp receives the high level, the microwave induction module is not invalid, the UV lamp can be started after the time of nT (n is more than 0), otherwise, the MCU controls the MCU to start the UV lamp after the time of delay T again, in the nT period of the delay protection again, if the MCU of the UV lamp receives the high level, the microwave induction module is not invalid, the UV lamp can be started after the time of nT, otherwise, the microwave induction module is invalid, the UV lamp cannot be started, and the alarm module needs self-checking alarm at the moment. The design of this step S4 mainly considers that the human movement will make the MCU receive the high level again, or the human does not leave yet, and the high level will not be generated, and by setting the nT period of the re-delay protection, it is detected whether the human leaves, and if the human leaves, the high level will be generated, otherwise it is highly likely that the microwave sensing module will fail.
Specifically, the delay T time in step S4 and step S5 is 2S to 5S. The delay T time is set to 2S in this example, and nT in step S5 is also 2S.
Specifically, the alarm module is a buzzer or an LED lamp capable of displaying red. In this embodiment, the alarm module is a buzzer.
Detailed description of the invention
The second embodiment is basically the same as the first embodiment, and the main differences are as follows: (1) the delay T time in step S4 and step S5 is 5S, and nT in step S5 is 3S. (2) The alarm module is an LED lamp capable of displaying red.
Detailed description of the invention
The third embodiment is basically the same as the first embodiment, and the main differences are as follows: (1) the delay T time in step S4 and step S5 is 3S, and nT in step S5 is 4S. (2) The alarm module is an LED lamp capable of displaying red.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
