Fig. 1 is a schematic structural diagram of an intelligent base measuring box capable of realizing self-diagnosis according to an embodiment of the present invention. As shown in fig. 1, the intelligent base measuring box comprises a self-diagnosis module 1, wherein the self-diagnosis module 1 comprises a diagnosis processing unit 10 and a reference standard unit 20 which are connected with each other, the reference standard unit 20 is used for obtaining a sampling reference value of a preset measurement parameter and sending the sampling reference value to the diagnosis processing unit 10, the diagnosis processing unit 10 is also connected with a sampling standard device 2 of the intelligent base measuring box, and is used for receiving a sampling standard value of the sampling standard device 2 for the preset measurement parameter and receiving the sampling reference value, comparing the sampling standard value with the sampling reference value and carrying out fault diagnosis on the sampling standard device 2 according to the numerical difference of the sampling standard value and the sampling reference value.
The intelligent base measuring box is used for detecting the electronic sonde. The intelligent base measuring box comprises a sampling standard value for acquiring a preset measuring parameter by the sampling standard device 2, the preset measuring parameter is determined according to the measuring parameter of the electronic sonde, for example, the current electronic sonde is mainly used for measuring temperature, relative humidity and air pressure, and then the preset measuring parameter can be set to comprise temperature, relative humidity and air pressure. The sampling standard 2 compares the measured sampling standard value with the corresponding measured value of the electronic sonde to detect the performance of the electronic sonde.
To realize effective detection of the electronic sonde, the sampling standard device 2 is ensured to work stably and reliably. Therefore, the embodiment of the invention realizes the intelligent diagnosis of the sampling standard 2 by arranging the self-diagnosis module 1 in the intelligent base measuring box. The self-diagnosis module 1 comprises a diagnosis processing unit 10 and a reference standard unit 20, wherein the reference standard unit 20 is used for acquiring a sampling reference value of a preset measurement parameter and sending the sampling reference value to the diagnosis processing unit 10. The reference standard unit 20 also realizes the sampling measurement of the preset measurement parameters, and compared with the sampling standard unit 2, the reference standard unit can adopt a measurement element with high reliability but lower precision, so that the cost is reduced on the basis of ensuring the measurement accuracy. Wherein the reference standard unit 20 provides reference data for qualitatively analyzing the sampling standard 2.
The diagnosis processing unit 10 is respectively connected with the reference standard unit 20 and the sampling standard unit 2, and is configured to receive a sampling reference value measured by the reference standard unit 20 and a sampling standard value measured by the sampling standard unit 2, compare the sampling standard value with the sampling reference value, and perform fault diagnosis on the sampling standard unit 2 according to a numerical difference between the sampling standard value and the sampling reference value.

Therefore, a highly reliable humidity-sensitive capacitor may be provided in the reference standard unit 20 to measure a reference value of the relative humidity, that is, the sampling reference value corresponding to the relative humidity, to compare with a sampling standard value measured by the sampling standard 2, and to find a fault in time.
Based on the embodiment, the embodiment of the invention improves the diagnosis reliability by setting the humidity-sensitive capacitor to measure the reference value of the relative humidity.
