In this embodiment, the working principle of the hand washing monitoring system is as follows:

when medical staff approach a hand basin, a first RFID directional antenna 2 arranged at the hand basin induces RFID tags 4 on wearing equipment of the medical staff, a fixed RFID reader-writer 1 reads medical staff identity information (such as the name, the job number, the post and other basic information of the medical staff) stored in the RFID tags 4, each RFID tag 4 has a unique ID number, the ID number is bound with the corresponding basic information of the medical staff, the read medical staff identity information is sent to a main control module 5, meanwhile, the main control module 5 receives the medical staff identity information sent by the fixed RFID reader-writer 1, and the time when the medical staff approach the hand basin and leave the hand basin is recorded according to the time information provided by a clock module 6 (namely, the time information is recorded); when a medical worker approaches a sickbed/operating table, the second RFID directional antenna 3 arranged at the sickbed/operating table senses the RFID tag 4 on the wearing equipment of the medical worker, the fixed RFID reader-writer 1 reads medical worker identity information stored in the RFID tag 4 and sends the read medical worker identity information to the main control module 5, and meanwhile, the main control module 5 receives the medical worker identity information sent by the fixed RFID reader-writer 1 and records the time (namely records the operation/nursing time information) when the medical worker approaches the sickbed/operating table according to the time information provided by the clock module 6. After recording the operation/care time information corresponding to a certain RFID tag 4, the main control module 5 queries whether hand washing time information corresponding to the RFID tag 4 is recorded within a preset time, and if no corresponding record is recorded, the main control module 5 controls a first alarm prompting module arranged at a hospital bed or an operating table to send an alarm prompt to prompt medical staff to wash hands before the operation/care.

It should be noted that the preset time may be set according to the hand washing rule before operation/nursing in a hospital, for example, the preset time may be 5 minutes, that is, when a medical staff approaches a hospital bed/operating table, whether to wash hands within 5 minutes, and if so, the preset time conforms to the corresponding hand washing rule; if the record of the hand washing of the medical staff at the hand washing basin exists, but the hand washing record is not within 5 minutes, or the hand washing record of the medical staff is not inquired, the corresponding hand washing rule is not met, and the main control module 5 controls the first alarm prompting device 7 to send out an alarm prompt.

Specifically, the wearing equipment of medical personnel comprises a worker plate, a work clothes and shoes. Preferably, in this embodiment, the RFID tag 4 is provided on a worker plate of the medical staff in order to facilitate attachment and detachment of the RFID tag 4.

Specifically, in the present embodiment, the RFID tag 4 is a passive microwave radio frequency tag. The microwave radio frequency tag is a general name of the ultrahigh frequency and microwave band RFID tag 4, and has long transmission distance and strong anti-interference capability. The working frequency of the passive microwave radio frequency tag used in the embodiment is 902MHz to 928 MHz. The diffraction capability of radio waves in ultrahigh frequency and microwave bands is weak, and no object can block between the transmitting antenna and the receiving antenna. Therefore, the reader antenna for the uhf and microwave band RFID tag 4 is designed as a directional antenna, and only the electronic tags within the directional beam range of the antenna can be read and written. The reader-writer antenna radiation field provides energy for the passive tag, the working distance of the passive tag is more than 1 meter, and the typical value is 4-7 meters. The antenna of the reader-writer sends a reading instruction to the active tag, and the active tag sends identification information stored by the tag to the reader-writer.
