The specific implementation mode is as follows: the following detailed description of embodiments of the invention refers to the accompanying drawings in which:
example (b): an intelligent warning device (see fig. 1 and 2) for an electric power operation site based on RFID comprises a main control system 1, wherein the main control system 1 is respectively connected with an RFID recognition system 2, a background server 3, a voice playing system 4 and a weather forecast system 5.
The main control system 1 comprises a single chip microcomputer 1-1, a memory 1-2, a key input detection circuit 1-3, a power module 1-4, a USB interface 1-5, an external network port 1-6 and an LED display screen 1-7, wherein the single chip microcomputer 1-1 is respectively connected with the memory 1-2, the key input detection circuit 1-3, the power module 1-4, the USB interface 1-5, the external network port 1-6 and the LED display screen 1-7, and the USB interface 1-5 and the external network port 1-6 are all connected with a background server 3.

The RFID reader has an important function of determining the working power of the whole RFID identification system, the working power of the RFID reader directly determines the identification distance between the RFID reader and the equipment electronic tag 2-1, and therefore the power regulator 2-5 can be controlled by the singlechip 1-1 in the main control system 1 to automatically regulate the working power of the RFID reader I2-3, so that the working power of the RFID reader can only identify one equipment electronic tag 2-1. However, when the electronic tag 2-2 of the on-site maintenance personnel is identified, the identification range needs to be relatively enlarged or fixed, and one RFID reader cannot be realized, so that two RFID readers need to be arranged, one is used for identifying the electronic tag of the equipment, and the other is used for identifying the electronic tag in the safety helmet of the maintenance personnel. The RFID reader I2-3 identifies the equipment electronic tag 2-1 after power is automatically adjusted, the RFID reader II 2-4 identifies the maintainer electronic tag 2-2 in the maintainer safety helmet, the RFID reader I2-3 and the RFID reader II 2-4 receive a modulation signal sent by the equipment electronic tag 2-1 and the maintainer electronic tag 2-2 and transmit the signal to the single chip microcomputer 1-1 to extract equipment voltage grade information, the single chip microcomputer 1-1 selects attention items and electric power safety procedure voice reminding information files at the corresponding voltage grade equipment during working, transmits the files to the voice decoding circuit 4-1 to be decoded, then amplifies the files through the audio amplification circuit 4-2, and finally plays the files through the loudspeaker 4-3. Meanwhile, the singlechip 1-1 checks the equipment name identified by the RFID reader I2-3 with the work ticket work place information, judges whether personnel mistakenly enter the electrified interval or not, and sends out an alarm prompt if the personnel mistakenly enter the electrified interval. Meanwhile, the RFID reader II 2-4 identifies the electronic tags 2-2 of the maintainers in the safety helmet of the operating personnel within a certain range, transmits the identified personnel number and personnel name information into the single chip microcomputer 1-1, checks the personnel number and names of the workers listed in the work ticket, judges whether the operating personnel in the work field conform to the list listed in the work ticket or not, and sends an alarm prompt if the operating personnel do not conform to the list listed in the work ticket. The single chip microcomputer 1-1 can control the position information of an operation site to be acquired through a position positioning module 5-2 in the weather forecast system 5 every 2 hours, the single chip microcomputer 5-1 is communicated with a mobile network through an antenna 5-1, a mobile communication module 5-3 sends the position information and a weather inquiry request to a weather station and a weather station, the weather forecast information returned by the weather station and the weather station is received by the antenna 5-1 after inquiry, the single chip microcomputer 1-1 in the main control system 1 controls an LED display screen 1-7 to display the weather forecast information and broadcasts the weather forecast information through a voice broadcasting system 4, and operators are informed of taking precautionary measures in advance according to relevant weather conditions. Workers can be reminded of broadcasting of common sense such as heatstroke prevention at high temperature, frostbite prevention at low temperature and the like according to weather conditions.
