Problems solved by technology

Although the above studies all use the energy metabolism rate to measure the labor intensity load and grade the labor intensity load, for specific handling tasks, the task designer can only understand the labor intensity level by looking up the table, and cannot measure the actual load. Labor-intensive loads, let alone formulate corresponding task plans based on specific factors such as handling weight, handling distance and lifting height

Abstract

The invention discloses a carrying task labor intensity load measurement experiment system and method. The system is formed by two adjustable placing benches, variable-weight carrying boxes and carrying information acquisition devices. The adjustable placing benches and the variable-weight carrying boxes are used for simulating carrying tasks under various work conditions; and the carrying information acquisition devices are used for synchronously collecting and simulating carrying frequency and carrying height in the carrying task process. The device can carry out unified planning and collection on key elements, such as carrying height, carrying frequency and carrying weight, for calculation of labor intensity under a specific carrying task, thereby reducing experiment errors and facilitating carrying out the experiment. The system and method can calculate the amount of heat produced by a human body in unit time, and determine labor intensity load of an actual carrying task based on design of carrying distance, carrying weight and carrying time and according to the collected carrying frequency.

Description

technical field [0001] The invention belongs to the technical field of ergonomics, and in particular relates to an experimental system and method for measuring the labor intensity load of a handling task. Background technique [0002] The handling task activities are mainly concentrated on the upper limbs and torso of the human body. Among them, the carrying distance, lifting height and cargo weight are the key factors that determine the labor intensity load in the handling task. Only by concentrating these factors together can the accurate determination and prediction of the handling task be carried out. Labor load, and formulate a suitable handling plan based on these elements to ensure engineering safety and work efficiency. Handling tasks are very common in our country. Although mechanical automation can be used for handling operations at present, due to the diversity and complexity of tasks, as well as the limitations of regional financial resources and technical condit...
