Dry and wet bulb temperature sensor detector and detection method for intensive baking room

Abstract

The invention relates to the technical field of sensors, in particular to a dry and wet bulb temperature sensor detector for a dense baking room, which includes an external interface and a single-chip microcomputer interface. Detection link; Step 2: Detecting the dry and wet bulb temperature sensor of the intensive baking room; Step 3: Detecting the temperature control error of the intensive baking room controller. The detector is used to quickly detect whether the dry and wet bulb temperature sensor of a dense roasting room is faulty, avoiding the tedious steps of manually connecting the controller and manually operating the controller, and improving the detection efficiency. Solve the problem that there is currently no method for judging whether the sensor meets the standard, and can not accurately judge whether the sensor is well matched with the controller, so as to avoid the problem that the sensor cannot work normally only during the baking process.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a dry and wet bulb temperature sensor detector and a detection method thereof for a dense baking room. Background technique [0002] "Technical Specifications for Intensive Barns (Trial) Revised Edition" (Guoyan Ban Zong [2009] No. 418) specifies the technical standards for dry and wet bulb temperature sensors in intensive barns. The bulb temperature, the wet bulb temperature of the upper shed, the dry bulb temperature of the lower shed, and the wet bulb temperature of the lower shed use the 5569-6P plug and specify the pin sequence. Dry and wet bulb temperature sensor failures and temperature control errors are common causes of baking losses, so sensors and controllers need to be inspected, repaired or replaced before, during and after the baking season. Although this technical standard has been implemented for more than ten years, there has been a lack of special testing equip...

AI Technical Summary

Problems solved by technology

There is a possibility of misjudgment in this judgment method. First of all, the timing characteristics of the sensor at different temperatures are slightly different, and it can work normally during detection, which does not mean that it can always work normally in the baking room environment.

Secondly, the controller reads the sensor data and removes the abnormal data after multiple acquisitions and displays it after filtering. The normal display in a short period of time does not prove that the sensor has been working normally, that is, there may be a high reading error rate.

Finally, dense barns generally have a variety of different types of controllers, and sensors need to be installed on each type of controller for detection. The workload is huge and labor-intensive
