Description

Technical Field

[0001] The present application relates to the field of sensor detection technology, and in particular to a high-precision air duct and water duct sensor detection system. Background Art

[0002] Current high-precision sensor detection and calibration methods have significant limitations and deficiencies, especially when faced with large-scale production needs. Traditionally, the detection and calibration process of high-precision air duct and water duct sensors (hereinafter referred to as high-precision air duct and water duct sensors) is handled one by one, and this process is highly dependent on manual operation.

[0003] Specifically, operators need to manually connect each sensor product to a computer and read the sensor output data through the serial communication interface. The data is then manually analyzed and judged by the operator based on their own professional knowledge and experience to determine whether the sensor needs to be calibrated and the specific parameters for calibration. This process is not only time-consuming and labor-intensive, but also greatly limits the improvement of production efficiency and cannot achieve batch operation.

[0004] In addition, since the detection and calibration process is highly dependent on human judgment, its accuracy and consistency are often difficult to guarantee. Human factors may lead to misjudgment or missed judgment, thereby increasing the error rate of the product. At the same time, this operation method also requires production personnel to have certain computer operation skills and a deep understanding of the internal register structure of the sensor, which undoubtedly increases the skill requirements for operators and increases the learning cost.

[0005] This traditional testing and calibration method is obviously disadvantageous for mass production. It not only prolongs the product production cycle and increases production costs, but also may affect the overall performance and market competitiveness of the product due to unstable quality caused by human factors.

[0145] In the formula, Vg represents the output voltage of the high-precision Feng Shui sensor; Vs represents the voltage value after the intelligent multi-channel thermometer measures stability; Vd represents the voltage difference between Vs and Vg; Vb represents the voltage compensation value; V represents the output voltage value of the high-precision Feng Shui sensor after compensation; the unit of voltage calibration is mV.

[0146] In this embodiment, the output voltage of the voltage-type high-precision Feng Shui sensor corresponds to the temperature and humidity scale calibration, and the voltages at points V1 and V2 are measured, where the voltages at points V1 and V2 correspond to the voltage values ​​converted from temperature and humidity, respectively. The standard outputs are 3300mV and 6700mV, respectively recorded as Vg. After waiting for 30 seconds to stabilize, the actual voltage values ​​at points V1 and V2 are measured by an intelligent multi-channel thermometer and recorded as Vs, respectively. Then, compensation calculations are performed respectively, and the compensation calculation results are recorded as Vb. Vb is written into the sensor register, and finally the correct output voltage is V.

[0147] The temperature and humidity scale conversion formula of the voltage-type high-precision wind and water sensor refers to Table 6 and Table 7. Table 6 is the temperature and humidity scale conversion formula of the voltage-type wind sensor (T (℃): temperature, RH (%RH): humidity); Table 7 is the temperature scale conversion formula of the voltage-type water sensor (T (℃): temperature) Table 6

[0151] In one embodiment, Figure 8 As shown, the global data communication function module specifically includes: obtaining the data of all registers of the high-precision Feng Shui sensor through serial port communication; reading the standard humidity value of the standard humidity sensor through serial port communication; accessing the thermometer through the Ethernet TCP / IP protocol to obtain the standard temperature value and the current and voltage values; and writing the compensation calculated data into the corresponding registers of the high-precision Feng Shui sensor through serial port communication.

[0152] In this embodiment, compared with the multi-source data reading module, the global data communication function module is also responsible for exchanging and transmitting data between different systems and devices. Since different sensors and devices may use different communication protocols and data formats, the data communication function module can handle these differences, realize protocol conversion and data format standardization, thereby ensuring interoperability between different devices.

[0153] In this embodiment, different types of high-precision Feng Shui sensors output different data types. For example, the current-type high-precision Feng Shui sensor outputs the temperature and humidity values ​​of the high-precision Feng Shui sensor through the current value, while the voltage-type high-precision Feng Shui sensor outputs the temperature and humidity values ​​through the voltage value. In the detection process of the high-precision Feng Shui sensor, multiple high-precision Feng Shui sensors are installed on the 36-way sensor detection tooling. If there are multiple current-type high-precision Feng Shui sensors at this time, the current value must be read by an intelligent multi-channel thermometer, and then the temperature and humidity values ​​are read. The current data read by the intelligent multi-channel thermometer is acquired into the detection system through the data communication function module of the high-precision Feng Shui sensor detection system in the form of TCP / IP communication. The detection system performs a series of operations such as parameter calibration on the current-type Feng Shui sensor through the above-mentioned multiple modules. The parameter calibration data is written into the register data of the current-type Feng Shui sensor through the 36-way sensor detection tooling in the form of serial communication. The voltage type is the same.

[0154] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
