Description

Temperature and humidity recorder

Technical Field

The utility model relates to a temperature and humidity measurement technical field especially relates to a humiture recorder.

Background

The humiture record appearance is the most commonly used mobilizable temperature and humidity measuring device at present, extensively is used for the monitoring of building indoor environment. The temperature and humidity recorder is usually internally provided with a battery, is provided with a temperature and humidity sensor or can be connected with an external temperature and humidity sensor to measure temperature and humidity, has the functions of recording and storing data and transmitting data, is provided with a key, and is convenient for maintenance personnel to operate the key nearby. The existing temperature and humidity recorder is an electronic paperless recorder. The electronic temperature and humidity recorder can accurately record and store data, and is convenient for downloading and storing the data. The temperature and humidity recorder of the U disk, which is introduced in recent years, enables the miniaturization of the temperature and humidity recorder to reach the utmost, and the mass temperature and humidity recorder is not limited by the number of traditional recording data sets, so that mass data storage is realized. Meanwhile, with the development of the internet of things and cloud technology, cloud storage thermometers for uploading data in real time are also widely used, and users can check and download data through a computer browser or a mobile phone at any time and any place.

However, currently, a humiture recorder for measuring an indoor environment generally does not have a positioning function, but in actual measurement, the humiture of an indoor test point is associated with an indoor position and environmental information of the test point, which is very important for accurately obtaining an indoor humiture field and analyzing humiture data. When indoor temperature and humidity measurement is carried out, the temperature and humidity of different points are measured by using the same temperature and humidity recorder generally, or a plurality of test points are placed in the same indoor space, particularly when the test space is large, the number of the test points is increased, so that if the position of each temperature and humidity recorder is not marked before each test, temperature and humidity data and the measurement position cannot be corresponded in the later stage. The method for manually marking the position adopted at the present stage is quite complicated, and even if the position is calibrated in many times, temperature and humidity data of the test point still cannot be matched with the spatial position due to later factors, so that the method is very unfavorable for accurately obtaining indoor temperature and humidity information, and even data analysis results are possibly wrong.

However, there are some humiture recorders with positioning function, such as a humiture recorder with outdoor positioning function based on a base station or GPS navigation, which is mainly used outdoors, for example, for cold chain transportation or field exploration, but is not suitable for positioning the indoor space of a building. The outdoor positioning and the indoor positioning have obvious difference, and the technical means are also far from each other. The outdoor positioning mainly acquires the position of a target on a map, and the positioning accuracy is not high, for example, the accuracy of GPS positioning is generally between 5 and 10 m; however, the indoor positioning mainly acquires the relative position of the target in the space in the building, belongs to small-range positioning, and requires high precision. For outdoor base station positioning, the distance between the devices is measured by the base station of the mobile operation network to determine the position of the devices, the accuracy of the positioning depends on the distribution and the coverage range of the base station, and sometimes, the error exceeds one kilometer. In addition, the GPS positioning is realized by sending a signal to a satellite by using a GPS positioning module on the device, and the positioning signal is weak when reaching the ground and cannot penetrate a building, so both are not suitable for indoor positioning of the building.

Therefore, it is necessary to provide a new humiture recorder suitable for indoor positioning.
