Sensor detection device and detection method thereof

Abstract

The invention belongs to the field of electronic technology, in particular to a sensor detection device and a detection method thereof. The sensor detection device comprises an LED (Light Emitting Diode) indicating device, a singlechip and a peripheral circuit of the singlechip, wherein the singlechip is connected with a time adjustment device, a light control adjustment device and a sensitivity adjustment device of a sensor and the LED indicating device through an I / O (Input / Output) port; and the singlechip is provided with an own A / D (Analog to Digital) and PWM (Pulse-Width Modulation) controller or is externally provided with an A / D and PWM controller. According to the detection device, when the integrity of the product time adjustment device, the light control adjustment device or the sensitivity adjustment device is assessed, only the time adjustment device, the light control adjustment device or the sensitivity adjustment device need to be adjusted respectively, and through observing the varying condition of an LED display device, the sound condition of the adjustment device can be judged. Experimental results demonstrate that 30-40 minutes is needed for detecting a product through a traditional method, but only 10 seconds is needed by the detection method provided by the invention, so that the production cost and the installation cost of the product are greatly saved.

Background technique [0002] With the progress of society, induction products are favored by more and more consumers due to their high intelligence. However, in the production process of current sensors, it is necessary to adjust the time delay, light control and sensitivity adjustment devices. Integrity testing, the usual testing process is: when testing the delay time, if the delay time of a product is 8 seconds to 20 minutes, set the delay time of the product to 8 seconds, after the product is powered on, wait for the product After entering a stable working state, sense the product. After the light is on, wait for 8 seconds without subsequent induction. If the light can be turned off, the 8-second sensing time is normal. To test the 10-minute delay time, you need to follow the above process Wait for 10 ...

[0002] With the progress of society, induction products are favored by more and more consumers due to their high intelligence. However, in the production process of current sensors, it is necessary to adjust the time delay, light control and sensitivity adjustment devices. Integrity testing, the usual testing process is: when testing the delay time, if the delay time of a product is 8 seconds to 20 minutes, set the delay time of the product to 8 seconds, after the product is powered on, wait for the product After entering a stable working state, sense the product. After the light is on, wait for 8 seconds without subsequent induction. If the light can be turned off, the 8-second sensing time is normal. To test the 10-minute delay time, you need to follow the above process Wait for 10 minutes to judge. When testing a certain time, you need to wait according to the above process to judge the integrity of the delay adjustment device. The same is true when testing the light control and sensitivity adjustment devices. Test in different sections, and repeatedly wait for the delay time to determine the integrity of each device, which greatly increases the production cost of the product and affects the efficiency of product production

In addition, when the user installs the sensor, in order to verify whether the adjustment parts are normal, the user also needs to install and debug the sensor according to the above tedious process, which increases the cost of product installation and greatly hinders the popularization of induction products. And in the process of installation, there is another problem that is also very time-consuming. For example, when the delay time needs to be set to a certain value within the delay time period, the time device needs to be adjusted, but what position should the time adjustment device be adjusted to? Is it the time we want to set? This requires constant adjustment, constant induction, and constant waiting to determine that the adjusted time is the time we want to set.

It is not difficult to see from the above situation that a sensor needs to go through a lot of manual testing from production to normal use by users. In this way, the production cost of the product will greatly increase, which is extremely unfavorable for the popularization of such energy-saving, intelligent and environmentally friendly products.
