Abstract

The invention discloses a device and a method for dynamically calculating the physical quantity of a sensor; the method comprises the following steps: setting corresponding formula configuration items for all physical quantity signal values or setting corresponding formula configuration items for all physical quantity signal values for different wireless sensor nodes; saving the corresponding relationship of the settings; receiving the physical quantity signal values measured by the wireless sensor nodes, and selectively receiving the identifies of the wireless sensor nodes; according to the physical quantity signal values or the wireless sensor node identifies and the physical quantity signal values, searching the corresponding formula configuration items from the saved corresponding relationship; and after finding the corresponding formula configuration items, and calculating the real physical quantity measured value according to the formula that the formula configuration items express. The technical scheme can dynamically increase or replace a sensor circuit board under the circumstance of not compiling the programs of an upper computer.

Description

technical field [0001] The invention relates to the field of measurement and control, in particular to a device and method for dynamically calculating the physical quantity of a sensor. Background technique [0002] In the industrial field, more and more enterprises use wireless sensor networks as a powerful guarantee for safe production. However, the physical quantity data collected by sensor nodes in wireless sensor networks needs to be transformed and calibrated in many cases. [0003] The shortcomings of the existing technology are high cost, low efficiency, time-consuming and other similar problems; once a certain standard 4-20mA or a certain standard 0-10V interface of the wireless sensor node is replaced with a sensor circuit board for measuring other types of physical quantities, Or to add sensor nodes, or to adjust the conversion formula, it is necessary to stop the running sensor monitoring system, modify and recompile the wireless sensor host computer program; th...
