Electric tool system for preventing hand of operator from getting hurt and control method

Abstract

The invention discloses an electric tool system for preventing a hand of an operator from getting hurt and a control method. The electric tool system comprises a wearable device and an electric tool. A passive ranging detection module is arranged in the wearable device. An active ranging detection module is arranged in the electric tool. The passive ranging detection module is in communication with the active ranging detection module in a wireless transmission manner. The active ranging detection module controls the electric tool to work. By means of the electric tool system, safety of the tool operator is enhanced. In the prior art, the operator can only be passively protected through protection covers and the like, the protection covers cannot be installed in some tools, and in the working process of the tools, the protection covers cannot completely protect cutting and grinding parts of the tools. According to the electric tool system, by means of the characteristic that RFID do not act until the RFID is within the range close to an antenna, the situation that the operator is too close to dangerous areas can be actively detected, and therefore running of motors is actively stopped and great superiority is achieved from the aspect of safety.

Description

technical field [0001] The invention discloses an electric tool system and a control method for preventing operator's hand injury, in particular, an electric tool for preventing operator's hand injury through RFID ranging technology. Background technique [0002] Please see attached figure 1 , electric tools 1 in the prior art, such as cutting saws, toothless saws, electric grinding wheels, etc., can only work when their moving parts are exposed, while the electric tools in the conventional technology are usually used for exposed cutting, grinding and other moving parts. It is simply to add a protective cover to protect the operator, and even some tools cannot even be installed with a protective cover. When the operator operates the tool for processing, he often needs one hand 2 to fix and reshape the workpiece to be processed. This kind of operation often occurs even if there is a protective cover because the hand is relatively close to the moving parts such as cutting and...

Problems solved by technology

[0002] Please see attached figure 1 , electric tools 1 in the prior art, such as cutting saws, toothless saws, electric grinding wheels, etc., can only work when their moving parts are exposed, while the electric tools in the conventional technology are usually used for exposed cutting, grinding and other moving parts. It is simply to add a protective cover to protect the operator, and even some tools cannot even be installed with a protective cover.

When the operator operates the tool for processing, he often needs one hand 2 to fix and reshape the workpiece to be processed. This kind of operation often occurs even if there is a protective cover because the hand is relatively close to the moving parts such as cutting and grinding of the tool.
