Problems solved by technology
For example, the detection process requires manual assistance, which cannot realize large-scale and automatic detection
Furthermore, automatic calibration cannot be performed on unqualified products
In addition, the inspection process cannot record product information, nor can ID input
Finally, the temperature sensor in the prior art can only perform temperature detection, but cannot perform photometric detection, which greatly limits the application range of the sensor

Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0023] figure 1 It is a structural schematic diagram of the sensor detection device of the present invention.
[0024] The sensor testing device of the present invention is mainly used to test the performance of one or more sensors to determine whether the sensing performance is within the acceptable range. In the present invention, the temperature value and photometric value sensing performance of the sensor are mainly detected. In a preferred embodiment, the sensor is a distributed indoor information sensor.
[0025] Such as figure 1 As shown, the sensor detection device mainly includes an incubator, a standard thermometer and a standard photometer, and a controller. The incubator communicates with the controller thr...

Provided is a test device and a test method for a sensor. The test device for the sensor comprises a constant temperature cabinet, a standard thermometer used for providing a standard temperature value, a standard photometer used for providing a standard photometric value and a controller, wherein the constant temperature cabinet can accommodate one or more than one to-be-tested sensor and provides a temperature value test environment and a photometric test environment for the to-be-tested sensor, the standard thermometer and the standard photometer are arranged in the constant temperature cabinet, and the controller is used for comparing the standard temperature value and the standard photometric value with a temperature value tested by the sensor and a photometric value tested by the sensor to judge whether the sensor is qualified or not and to correct an unqualified product. According to the test device and the test method for the sensor, manual intervention can be needless, automatic test and automatic correction of the temperature and the luminosity of mass sensors can be achieved at the same time, product status and corresponding identification (ID) number can be recorded, and therefore, test efficiency and correction efficiency are improved, cost is saved, and product status traceability is facilitated.
Description
technical field [0001] The invention relates to sensor detection technology, in particular to a device and method for batch automatic detection and / or calibration of more than one sensor at the same time. Background technique [0002] Distributed indoor information sensor is a kind of sensor, which is a comprehensive sensor integrating ultrasonic human body detection technology, pyroelectric human body detection technology, temperature detection technology, photometric detection technology, single-chip processing technology and data communication technology. Provide comprehensive information on human presence, luminosity and temperature for smart home control systems. [0003] At present, the temperature detection technology of the sensor is to use thermistor and single-chip A / D (analog-to-digital conversion) detection technology to detect the ambient temperature. The photometric detection technology of the sensor is to use the photoresistor and single-chip A / D detection te...
