RFID label tag, wherein photosensitive circuit includes photo resistance, twin voltage comparator and triode, when the correct safe wearing of staff
When cap, illumination condition locating for photosensitive circuit is poor, the variation of photosensitive circuit light characteristics, at this time the 2nd RFID mark with photosensitive circuit
Label can be identified that, when staff does not have safe wearing cap, illumination condition locating for photosensitive circuit is good by RFID reader, this
When the second RFID label tag with photosensitive circuit can not be identified by RFID reader；When staff does not have safe wearing cap, light
Illumination condition locating for quick circuit is good, and the second RFID label tag with photosensitive circuit can not be identified by RFID reader at this time；It is hot
After outer sensor detects staff, it will test signal and be sent to singlechip controller, the timing by singlechip controller,
If RFID reader is unidentified in 5s arrives any RFID label tag, representative has staff's cap not safe to carry to enter production
Operating area, singlechip controller sends a signal to warning device at this time, and warning device is directly alarmed；If RFID is read in 5s
It reads device and only recognizes the first RFID label tag, though then illustrate that staff's cap safe to carry is not worn on head correctly, this signal
It is sent to singlechip controller, singlechip controller sends a signal to warning device, and warning device is directly alarmed, while single
The label information recognized is sent to computer memory system by piece machine controller, carries out storage note by computer memory system
Record；If RFID reader recognizes the first RFID label tag and the second RFID label tag with photosensitive circuit simultaneously in 5s, illustrate
Staff is correct, and safe wearing cap enters production operation region, this signal is sent to singlechip controller, at this time warning device
It does not alarm, singlechip controller sends a signal to voice device, and " you have entered production scene, it is noted that peace for voice device sending
Voice prompting entirely ".
The configuration of the present invention is simple, convenient and easy, measurement is accurate and has a wide range of application, while can detect peace like clockwork
Full cap wear condition simultaneously issues warning in time.

Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Fig. 1-3 is please referred to, power plant's specific region method for safety monitoring, 5 side of channel in neighbouring production operation region 6 is by giving birth to
It produces operating area 6 and is successively arranged warning device 1 and infrared sensor 4 outward, the spacing of the infrared sensor 4 and warning device 1
For 1.75m, the height of warning device 1 and infrared sensor 4 apart from ground is 1.5m, warning device 1 and production operation region 6
Spacing be 20m, 5 other side of channel in neighbouring production operation region 6 is successively arranged voice device by production operation region 6 outward
3 and RFID reader 2, the voice device 3 be oppositely arranged with warning device 1, RFID reader 2 and the spacing of voice device 3 are
0.75m, the height of voice device 3 and RFID reader 2 apart from ground are 1.6m, singlechip controller pass through respectively route with
Warning device 1, voice device 3, infrared sensor 4, RFID reader 3 are connected with computer memory system, whole device by
The inside of 220V power supply power supply, safety cap 7 is equipped with the first RFID label tag and the second RFID label tag with photosensitive circuit, wherein light
Quick circuit includes photo resistance, twin voltage comparator and triode, when the correct safe wearing cap 7 of staff, photosensitive circuit
Locating illumination condition is poor, and the variation of photosensitive circuit light characteristics, the second RFID label tag with photosensitive circuit can be by RFID at this time
Reader identification, after infrared sensor 4 detects staff, will test signal and is sent to singlechip controller, by monolithic
Machine controller starts timing, if RFID reader 2 is unidentified in 5s arrives any RFID label tag, representative has staff not
Cap 7 safe to carry enters production operation region, and singlechip controller sends a signal to warning device 1 at this time, and warning device 1 is direct
It alarms；If RFID reader 2 only recognizes the first RFID label tag in 5s, though illustrate staff's cap 7 safe to carry
It is not worn on head correctly, this signal is sent to singlechip controller, and singlechip controller sends a signal to warning device 1, report
Alarm device 1 is directly alarmed, while the label information recognized is sent to computer memory system by singlechip controller, by
Computer memory system carries out storage record；If RFID reader 2 recognizes the first RFID label tag and with photosensitive simultaneously in 5s
Second RFID label tag of circuit then illustrates that the correct safe wearing cap 7 of staff enters production operation region 5, the transmission of this signal
To singlechip controller, warning device 1 is not alarmed at this time, and singlechip controller sends a signal to voice device 3, voice device 3
Issue the voice prompting of " you have entered production scene, it is noted that safety ".
As shown in figure 3, when safety cap is correctly worn, light is blocked the working principle of photosensitive circuit by head, this time
Quick resistance is larger, and 6 voltage of pin of LM393 is higher than pin 5, and triode Q1 is connected and to second in LM393 output low level
RFID label tag power supply, at this point, RFID reader can correctly read label information, i.e. staff's correct safe wearing
Cap；On the contrary, safety cap is not worn on the head, extraneous light will cause photo resistance R8 substantially to reduce, 5 voltage of pin of LM393
Higher than pin 6, LM393 output open circuit, pull-up resistor makes LM393 output end generate high level, at this point, triode Q1 ends, electricity
Road stops powering to the second RFID label tag, at this point, RFID reader can not read label information, i.e. staff is not correct
Safe wearing cap.
The violation record of related personnel by the record of inspection computer memory system, can be obtained, monthly convenient for safety
Management.
The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party
Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective
It makes a variety of changes.
