An automatic quality measurement system for constant temperature and humidity chamber

Abstract

The invention relates to an automatic quality measurement system in a constant temperature and humidity box. A plurality of sample trays are arranged in the constant temperature and humidity box; a force sensor is arranged inside each sample tray. The constant temperature and humidity box comprises a control module, a data acquisition module, a computation module and a display and alarm module, wherein the data acquisition module collects the data of the force sensors and transmits the data to the control module according to instructions of the control module; the control module controls the measurement channels of the force sensors to measure quality, and stores the multi-measurement time and corresponding measurement quality into a memory; the computation module takes measurement data in real time and judges conditions; after the control module transmits the measured force sensor No. to the display and alarm module, the display and alarm module displays the corresponding force sensor No. and raises the alarm. According to the invention, the detection time is saved, the regulating process is controlled automatically, alarm reminding and display are achieved, the states of all samples are absolutely clear, and the operation is convenient.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to an automatic quality measurement system for constant temperature and humidity chambers. Background technique [0002] Before the fire detection and combustion performance test of building materials, the test samples need to be adjusted according to the legal standards corresponding to the test (temperature, humidity), so that the test is representative and reproducible. The current measurement method and its working state: use constant temperature and humidity test chamber, electronic balance, and quartz clock. The staff need to take out each sample from the constant temperature and humidity test chamber many times during the adjustment process and weigh it with an electronic balance. The time is manually set by a quartz clock, and the human error is relatively large; after each weighing, the relevant personnel need to sort out and calculate the data, and the workload of the pers...

The current measurement method and its working state: use constant temperature and humidity test chamber, electronic balance, and quartz clock. The staff need to take out each sample from the constant temperature and humidity test chamber many times during the adjustment process and weigh it with an electronic balance. The time is manually set by a quartz clock, and the human error is relatively large; after each weighing, the relevant personnel need to sort out and calculate the data, and the workload of the personnel is heavy; the corresponding personnel need to weigh the samples on time, which increases the workload of the personnel

Due to the above reasons, newly arrived samples need to be adjusted together with other samples at the specified time, and cannot be adjusted at any time, and the adjustment efficiency is extremely low
