PURPOSE: An opening and closing detector using an RFID(Radio Frequency Identification) is provided to immediately sense a trespassing area from a central control office when sensing external trespassing by including an identification code in each apparatus which is arranged in each an entrance and places to be trespassed. CONSTITUTION: An inductive supply part(22) includes an electrical generation induction receiving coil(22a). An electrical generation induction receiving coil generates power by reacting to an electromotive force line which is generated in a fixed sensing device(20). A private code value is operated while being connected with the inductive supply part and is recorded in a code value memory(24). A driving sensing device includes the code value memory and a transmission part(28). The transmission part transmits the code value of the code value memory to the fixed sensing device. An electromotive force generation coil(42a) generates an electromotive force line so that an electromotive force is applied to the electrical generation induction receiving coil of the driving sensing device. |
