The invention discloses an automatic measuring device for multi-field simultaneous automatic measurement in an indoor environment field. The automatic measuring device comprises a three-dimensional motion system, a control system and a data acquisition system. The three-dimensional motion system is composed of a longitudinal linear module, a vertical linear module and a transverse linear module according to a three-dimensional coordinate axis mode and an instrument carrying platform for installation of a measuring instrument can be arranged on the three-dimensional motion system. The control system comprises a human-computer interface device, a programmable logic controller and three motor drivers. The data acquisition system comprises the measuring instrument, the programmable logic controller, a data acquisition card and a computer. The automatic measuring device can achieve multi-field simultaneous measurement of the environment field and reduce errors caused by asynchrony of multi-field measurement time, integration of control and measurement is achieved, influence on an experiment by personnel is reduced, the accuracy and efficiency of a test are improved, personnel operation is simplified, time spent on manual data processing is shortened, and errors of manual data processing are reduced.

Description

Technical field [0001] The invention belongs to a measuring device, in particular, it relates to a three-dimensional automatic measuring device used for simultaneous testing of multiple fields in an indoor environment field. Background technique [0002] In order to study indoor air flow, temperature distribution, pollutant transmission law, etc., and ensure the comfort and health of the indoor environment, it is necessary to measure the temperature field, velocity field, concentration field and other environmental fields in a specific space. How to accurately locate and achieve high-efficiency measurement of various environmental field measurement instruments has become a key difficulty for environmental field measurement in characteristic spaces. [0003] At present, the measurement of the environment in a specific space usually adopts an adjustable bracket to carry a measuring instrument, and a ruler is used to determine the spatial position of the measuring point. Using this m...

Problems solved by technology

[0004] The present invention aims to solve the technical problems of positioning error caused by the existing manually operated adjustable bracket and ruler positioning, and the measurement field error caused by the activities of experimenters in the measurement area. It provides a multi-field simultaneous automatic measurement device for indoor environmental fields. The three-dimensional motion system replaces manual operation, which can not only perform precise positioning, avoid the influence of measuring personnel on the flow field, but also save measurement time, reduce the number of people to be measured, reduce measurement costs, and improve measurement efficiency. Simultaneous measurement of the field, automatically pairing and outputting the environmental field information measured by the measuring instrument with the spatial coordinates where the measuring instrument is located, reducing the error caused by the asynchronous measurement time of multiple fields and the time of manual data processing
