Summary of the invention

To be solved in the utility model is exactly the existing employed identify label device of colliery underground labour's work attendance, substitute by other people easily and check card, cause problems such as certain leak for the attendance management of going into the well, and provide a kind of simple in structure, be easy to make, esy to use, safe and reliable and can in personnel's attendance management is gone into the well in the colliery, reach and can't substitute the new device of checking card.

Technical solution of the present utility model is to realize like this.The safety cap that has induction marker, comprise safety cap, RF identification sign device, RF identification sign device is formed by connecting with parallel way by inductance coil, capacitor and RFID IC chip according to the coiling of safety cap inner wall shape, RF identification sign device places the safety cap inwall, by encapsulating material this RF identification sign device and safety cap is bonded to one.

Described encapsulating material is insoluble adhesive.

The package position of described RF identification sign device in safety cap can also can be at sidewall at the top of safety cap inwall.

The packaged type of described RF identification sign device can directly identify RF identification device and finished product safety cap bonding and form, and also can in safety cap manufacturing process RF identification be identified device and embed in the helmet shell one-shot forming.

Noncontact RF identification (RFID) principle of the utility model application of known identifies device with RF identification and safety cap is combined as a whole cleverly.Owing to go into the well and must wear, and do not have maintenance problem in safety cap one people one top, thus can the guarantor, card is corresponding; Concentrator marker and safety cap become one, can't separate unless damage, thereby prevent for checking card behavior.Increase any added burden can not for the workman that goes into the well with the incorporate concentrator marker of safety cap, the sphere of action that only need enter card reader when the workman checks card gets final product, even without any need for specially the action of checking card.This for usually will be pickaback, the workman and the crowded situation advantageous particularly of upper and lower well time of portable various tool, material.

When the workman passed through the sphere of action of attendance recorder card reader in the last process of going into the well, RF identification sign device was subjected to the excitation of card reader, just the identification code that is solidificated in the RF identification sign device can be sent, and card reader is with the identification code input attendance recorder that receives.Attendance recorder forms attendance record with each identify label sign indicating number and the combination of temporal information at that time, is sent to host computer by the attendance recorder communication interface, for the various management softwares uses information-related with work attendance.
