Introduction of GB/T 44299-2024

GB/T 44299-2024 Methods of measurement and declaration of the detection range of detectors-Passive infrared detectors for major and minor motion detection 1 Scope This document specifies the general test requirements, test environment, test equipment, test procedures and expression of test results for passive infrared detectors for major and minor motion detection. This document is applicable to the methods and declaration of measurement and declaration of the detection range of detectors for passive infrared detectors for major and minor motion detection. The detectors can be stand-alone (direct control of one or more applications) or as part of home and building electronic systems or building automation control systems (HBES/BACS) or similar. This document specifies methods and test procedures for the detection range of detectors to declare and verify the detection area for motion detectors using passive infrared technology in electronic control devices and appliance switches. It also provides a uniform way to present the test results. The purpose of these detectors is to detect the major and minor movements of persons. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: - IEC Electropedia: available at http://www.electropedia.org/ - ISO Online browsing platform: available at http://www.iso.org/obp 3.1 infrared; IR optical radiation for which the wavelengths in vacuum are longer than those for visible radiation, that is approximately between 780 nm and 1 mm [Source: GB/T 14733.12-2008, 731-01-05] 3.2 passive infrared detector electronic detector that measures infrared (IR) light radiating from humans in its field of view 3.3 motion detector unit detecting motion that can be part of an electronic control device or an appliance switch Note: "Electronic control device" is used as a general term to cover electronic switches, HBES/BACS switches and electronic extension units. 3.4 major motion movement of a person walking into an area or walking within an area 3.5 minor motion small movements of a person or a part of a person within an area Note 1: Typical examples of minor motion are in working areas, for example, offices, classrooms, meeting rooms, where the attendance time is long, and the motions of the persons are small (e. g. sitting activities with arm movements). Note 2: Non-standardized terms for a minor motion detector are "presence detector" or "occupancy detector". 3.6 radial motion motion directly toward the motion detector Example: See Figure 1. 3.7 tangential motion motion laterally or obliquely to the motion detector Example: See Figure 2. 3.8 detection area surface area in which the detector is specified to detect the motion of a person Example: See Figure 3 3.9 non-detection area surface area where detection is not expected Note: Although it becomes unlikely that detection of persons will occur, triggering of the detector is not excluded in this area. 3.10 sensitivity degree of response of a detector to an incoming signal Note: Depending on the technology, sensitivity can be adjusted for certain parameters (e.g. range, amplification of infrared signal). 3.11 delay-time duration of time from the moment the motion was last detected until the status of the controlled load is changed 3.12 dead time time during which the detector is unable to detect after the delay-time and at start up 4 General requirements on tests Detectors shall be mounted and installed according to the manufacturer's instructions. Manufacturer's instructions regarding operation shall be applied to all tests, where applicable. It is allowed to set the delay-time of detectors at minimum setting or in test mode. The sensitivity is set at maximum. Note 1: A modification of the detector software with a minimum value of 5 s for the delay-time can be necessary to shorten the test time in total. During the test, the detectors shall be able to activate the load independently of the light level in the test room. The dead time of the detector shall be considered according to the manufacturer's instructions. The timing of any persons' (dummy) movement and any test arm movement shall be adjusted accordingly. Tests according to this document are type tests. Note 2: Type tests are defined in GB/T 4210-2015, 581-21-08.
