Problems solved by technology

The vast majority of existing WBGT thermal stress measurement systems on the market are portable systems, not designed for continuous measurement outdoors
In addition, the sensors of these systems are mounted close together for portability, thus preventing the free circulation of air between the sensors

Abstract

The invention discloses a heat stress monitoring system and a field apparatus thereof. The heat stress monitoring system comprises the field apparatus and real-time monitoring equipment, wherein the field apparatus comprises a WBGT measuring device, a position measuring device for acquiring the position of the field apparatus, a data processing device, a data communication device and a power supply device, wherein the WBGT measuring device is positioned in field environment and comprises a dry-bulb temperature measuring unit, a black-bulb temperature measuring unit and a natural wet-bulb temperature measuring unit; the data processing device is used for acquiring and processing all related temperature data acquired by the WBGT measuring device, further calculating WBGT heat stress temperature data, and sending all the related temperature data and calculated data; and the data communication device is used for communicating with the data processing device and receiving the related temperature and the calculated data sent by the data processing device. The system can realize long-time detection of the WBGT heat stress temperature in far-end outdoor environment and displays quality control data in a central station in real time.

Description

technical field [0001] The invention relates to a heat stress monitoring system, in particular to a monitoring system for real-time measurement of wet bulb temperature (WBGT) heat stress in an outdoor environment and a field device thereof. Background technique [0002] The thermal comfort experienced by humans or animals mainly depends on wind speed, air temperature, relative humidity and solar radiation. The WBGT heat stress index is a composite temperature used to assess the impact of the above four environmental factors on humans or animals. The index was developed in the late 1950s for the US Marine Corps Recruit Depot on Parris Island in South Carolina (South Carolina). The method of measuring the WBGT thermal stress index was standardized in 1982. This measurement standard is recorded in ISO 7243 document (1989 edition), and also published in British Standard BS EN 27243 (British Standard BSEN 27243) document. [0003] According to ISO 7243 document, WBGT thermal s...
