Abstract

This utility model discloses a kind of electric tool system preventing operator's hands injured, electric tool system includes wearable device and electric tool, passive ranging detection module it is provided with in wearable device, initiative range measurement detection module it is provided with in electric tool, being communicated by wireless transmission method between passive ranging detection module and initiative range measurement detection module, initiative range measurement detection module controls electric tool work.This utility model strengthens the safety of tool operation person: prior art can only be by passive protection operators such as protective covers; in some instrument, protective cover all cannot be installed; and instrument is in the course of the work; protective cover is the cutting of instrument, polishing part to be protected completely completely; the feature that this utility model is just worked in the scope nearer apart from antenna by RFID; can actively detect that operator's distance deathtrap is the nearest; thus the operation stopping motor actively; for secure context, have an enormous advantage.

Description

Prevent the electric tool system that operator's hands is injured

Technical field

This utility model discloses a kind of electric tool system preventing operator's hands injured, and particularly one is passed through RFID ranging technology prevents the electric tool that operator's hands is injured.

Background technology

Refer to accompanying drawing 1, electric tool 1 of the prior art, such as cast-cutting saw, toothless saw, electricity emery wheel etc., Its moving component is wanted exposed and the most just can be operated, and the electric tool in routine techniques is for cutting of exposing Cut, the moving component such as polishing is generally only and simple protects operator plus protective cover, even has A little instrument protective covers all cannot be installed.Operator are when operation instrument is processed, it is often necessary to one The operations such as processed workpiece is fixed by hands 2, shaping, this operation is due to hands relatively instrument The moving components such as cutting, polishing, even if there being protective cover also frequent generating tool to accidentally injure phenomenon.

Summary of the invention

The shortcoming easily accidentally injuring operator's hands for electric tool of the prior art mentioned above, this reality With a kind of electric tool preventing operator's hands injured of novel offer, it is by the pendant with range finding detection module Wearing device coordinates electric tool to use, and can effectively solve the problems referred to above.

This utility model solves its technical problem and the technical scheme is that and a kind of prevent operator's hands injured Electric tool system, electric tool system includes wearable device and electric tool, and it is passive to be provided with in wearable device Range finding detection module, is provided with initiative range measurement detection module, passive ranging detection module and active in electric tool Being communicated by wireless transmission method between range finding detection module, initiative range measurement detection module controls electronic work Tool work.

This utility model solves the technical scheme of its technical problem employing and further comprises:

Described wearable device is glove, bracelet or finger ring.

Described passive ranging detection module uses RFID, and initiative range measurement detection module includes Rfid interrogator and circuit for controlling motor, rfid interrogator output control signal is to circuit for controlling motor.

Described rfid interrogator includes RFID detection antenna and RFID testing circuit, and RFID detects antenna Receive the signal of RFID, and be transferred to RFID testing circuit.

The beneficial effects of the utility model are: this utility model strengthens the safety of tool operation person: existing skill Art can only be by passive protection operators such as protective covers, and in some instrument, protective cover all cannot be installed, And instrument is in the course of the work, protective cover is the cutting of instrument, polishing part to be protected completely completely Get up, the feature that this utility model is just worked in the scope nearer apart from antenna by RFID, can be actively Detect that operator's distance deathtrap is the nearest, thus the operation of stopping motor actively, from secure side For face, have an enormous advantage.

Below in conjunction with the drawings and specific embodiments, this utility model is described further.

Accompanying drawing explanation

Fig. 1 is conventional instrument protection schematic diagram.

Fig. 2 is that this utility model instrument protects schematic diagram

Fig. 3 is this utility model instrument control block.

In figure, 1-electric tool, 2-staff, 3-glove, 4-RFID read write line, 5-RFID electronic tag.

Detailed description of the invention

The present embodiment is this utility model preferred implementation, other its principles all and basic structure and this enforcement Example is identical or approximation, all within this utility model protection domain.

Refer to accompanying drawing 2 and accompanying drawing 3, this utility model mainly includes wearable device and electric tool two large divisions Composition, in the present embodiment, wearable device is preferably glove 3, when being embodied as, it is also possible to uses bracelet, refer to Rings etc., are provided with passive ranging detection module in wearable device, be provided with initiative range measurement detection mould in electric tool 1 Block, in the present embodiment, range finding detection uses RFID technique, and passive ranging detection module uses RFID electronics Label 5, initiative range measurement detection module uses rfid interrogator 4 and circuit for controlling motor, rfid interrogator Output control signal, to circuit for controlling motor, controls motor work, and in the present embodiment, rfid interrogator is main Including RFID detection antenna and RFID testing circuit, RFID detection antenna receives the letter of RFID Number, and be transferred to RFID testing circuit, RFID testing circuit output control signal to circuit for controlling motor, Control motor work.

To illustrate this utility model with instantiation below, this utility model mainly includes built-in The glove of RFID, RFID detection antenna, RFID testing circuit and circuit for controlling motor, RFID Testing circuit by RFID detection antenna send radio wave to the RFID being built in glove, Meanwhile, after the electric wave that the RFID during antenna receives glove sends, return id information etc. are to RFID Testing circuit, and carry out distance calculation, RFID testing circuit receives the id information of return, and finds range After calculating, determine the operation controlling motor, when RFID and RFID detect the distance between antenna During less than the safe distance threshold value set, RFID testing circuit notice circuit for controlling motor stops motor and runs. In the present embodiment, RFID testing circuit is additionally provided with RFID device and unlocks logic, need before running after powered up Want effective RFID to carry out equipment unblock, prevent in the non-wearing gloves of operator or glove RFID inefficacy etc..

The using method of control equipment of the present utility model is: worn built-in RFID electronics before operation instrument The glove of label, up tool power supply, glove are carried out instrument unblock near device RF ID detection antenna, will Glove are removed to outside safe distance, and opener is processed.When glove detect antenna detection near RFID In the range of i.e. (distance between RFID and RFID detection antenna is less than the safe distance threshold set Value), motor is out of service.

This utility model strengthens the safety of tool operation person: prior art can only be passive by protective cover etc. Protection operator, in some instrument, protective cover all cannot be installed, and instrument is in the course of the work, anti- Guard shield is the cutting of instrument, polishing part to be protected completely completely, and this utility model passes through RFID The feature just worked in the scope that distance antenna is nearer, can actively detect that operator's distance is dangerous Region is the nearest, thus the operation stopping motor actively, for secure context, have an enormous advantage.
