Introduction

This document describes the test procedures and guidelines for object detection systems (ODSs) and their visual aids (VAs), which prompt the The machine has objects in the monitoring area. Appropriate on-site management, driver training and the adoption of relevant vision standards (GB/T 16937 and GB/T 25685) assist in solving the problem of on-site personnel problems. staff safety issues. In some cases, the driver cannot obtain the field of view of the work area through direct vision or indirectly through the use of surveillance mirrors. In this kind of In some cases, the driver's vision can be improved by using ODSs and their VAs. ODSs and their VAs provide the driver with information on whether a person or object is in the path of the machine's movement (mainly when reversing). Both ODSs and their VAs have advantages and disadvantages. System users need to recognize and understand the shortcomings of ODSs and their VAs. Appendix A summarizes the Advantages and disadvantages of the selected device. It is important to note that ODSs and their VAs have both advantages and disadvantages. No device can perform perfectly in all situations. system user It is very important to identify and understand the drawbacks of ODSs and their VAs, and Appendix A lists the advantages and disadvantages of the selected devices. Haptic signals are currently being used in the automotive industry, so the use of tactile signals in ODS warning devices was discussed during the revision of this document. Sensory signals (signals that stimulate the driver to touch, including vibration, force, and movement) replace visual and auditory signals. While this document currently does not allow An alarm device that uses tactile signals, but may be incorporated into the alarm device as a supplement to visual and audible signals. Apply touch on earth moving machinery The validity of sensory signals needs more research to be sure. Earth-moving Machinery Object Monitoring System and Its Visualization Auxiliary device performance requirements and tests

1 Scope

This document specifies general requirements for the performance of object detection systems (ODSs) and their visual aids (VAs) used on earth-moving machinery and description methods for evaluation and testing, including the following. --- Surveillance and/or visualization of objects including personnel in the surveillance area; ---Visual and/or audible alarms for test personnel and personnel in the monitoring area (if applicable); --- Reliability of system operation; --- System compatibility and environment description. This document applies to earth-moving machinery as defined in ISO 6165.ODS and/or VA can be used to increase the driver's direct field of view (see ISO 5006) or indirect vision when using a surveillance mirror (see ISO 14401). Additionally, ODS and/or VA can be used for object monitoring or Field of view provides additional methods, for example. consideration of ergonomic limitations on direct field of view effects, avoiding repeated rotation of the head and upper body.
