Because the bucket is made of high-strength alloy steel materials, the equipment such as a crushing and screening device of a mineral processing system can be seriously damaged, and huge economic loss is often caused. The current mode for solving the problem of bucket falling is complex and expensive, or needs active signals, and has short continuous working time and poor anti-interference capability.
Disclosure of Invention
In order to solve the problems, the invention provides an electric bucket tooth falling real-time monitoring alarm method and an alarm device based on the technology of the internet of things. The technical problems of complex and expensive structure, poor anti-interference capability and short maintenance working time in the prior art are solved.
In order to achieve the purpose, the invention adopts the technical scheme that: an electric bucket tooth falling real-time monitoring and alarming method based on the Internet of things technology comprises the following steps:
1) independent codes are written in the radio frequency identification electronic tags in advance, and corresponding electronic tag card readers are arranged in a cab of a host of the electric shovel;
2) a circular hole is formed in the electric bucket tooth at the installation position of the electric bucket body; installing an electronic tag packaging module with a radio frequency identification electronic tag inside a circular hole, and installing a compression spring in the circular hole;
3) when the electric bucket tooth normally works, the electronic tag packaging module is in a closed state and cannot be captured and read by a remote electronic tag card reader; when the electric bucket teeth fall off, the compression spring ejects the electronic tag packaging module to remove the shielding state, and the electronic tag card reader captures and reads data;
4) and after the electronic tag card reader reads corresponding data, processing the data, determining the position of the falling electric bucket teeth according to codes, and giving an alarm.
A circular hole is formed in the electric bucket tooth, the circular hole is formed in the installation position of the electric bucket tooth and the electric bucket body, and a compression spring and an electronic tag packaging module are arranged in the circular hole; the compression spring is in a compression state, one end of the compression spring abuts against the electronic tag packaging module, and the other end of the compression spring abuts against the inside of the electric shovel bucket body; when the electric bucket teeth fall off, the compression spring pops up the electronic tag packaging module.
The electronic tag packaging module is a cylindrical ceramic packaging block, and a radio frequency identification electronic tag is packaged in the electronic tag packaging module.
The radio frequency identification electronic tag is specifically an ultrahigh frequency passive radio frequency identification electronic tag with the frequency of 300HZ-3000 HZ.
The radio frequency identification electronic tag is internally written with independent codes.
The beneficial effects created by the invention are as follows: the electronic tag porcelain piece packaging structure is simple, the passive device can withstand harsh external environment and keep a long-term installation state, the packaging module synchronously pops up to remove a shielding state when the bucket teeth fall off, dynamic data can be accurately and automatically captured through the non-contact card reader, real-time monitoring is achieved, an alarm is given in time, effective remedial measures can be taken in time, loss is avoided, high economic benefits and social benefits are achieved, and popularization is facilitated.

Detailed Description
An electric bucket tooth falling real-time monitoring and alarming method based on the Internet of things technology comprises the following steps:
1) independent codes are written in the radio frequency identification electronic tag 1-1 in advance, and a corresponding electronic tag card reader is arranged in a cab of a host of the electric shovel;
2) a circular hole 5 is formed in the electric bucket tooth 3 at the position where the electric bucket body 2 is installed; installing an electronic tag packaging module 1 with a radio frequency identification electronic tag 1-1 inside a circular hole 5, and installing a compression spring 4 in the circular hole 5;
3) when the electric bucket tooth 3 works normally, the electronic tag packaging module 1 is in a closed state and cannot be captured and read by a remote electronic tag card reader; when the electric bucket teeth 3 fall off, the compression spring 4 ejects the electronic tag packaging module 1 to remove the shielding state, and the electronic tag card reader captures and reads data;
4) and after the electronic tag card reader reads corresponding data, processing the data, determining the position of the falling electric bucket teeth 3 according to codes, and giving an alarm.
An alarm device, its structure is: a circular hole 5 is formed in the electric bucket tooth 3, the circular hole 5 is formed in the installation position of the electric bucket tooth 3 and the electric bucket body 2, and a compression spring 4 and an electronic tag packaging module 1 are arranged in the circular hole 5; the compression spring 4 is in a compressed state, one end of the compression spring abuts against the electronic tag packaging module 1, and the other end of the compression spring abuts against the inside of the electric shovel bucket body 2; when the electric bucket teeth 3 fall off, the compression spring 4 ejects the electronic tag packaging module 1. The electronic tag packaging module 1 is a cylindrical ceramic packaging block, and a radio frequency identification electronic tag 1-1 is packaged in the electronic tag packaging module.
The radio frequency identification electronic tag 1-1 is specifically an ultrahigh frequency passive radio frequency identification electronic tag with the frequency of 300HZ-3000HZ, and an independent code is written in the radio frequency identification electronic tag 1-1. When the alarm device is used, the alarm device can be arranged at different positions needing to be detected, and multipoint monitoring is arranged. Because each RFID tag 1-1 is internally coded independently, the RFID tags do not interfere with each other.
