Abstract

PROBLEM TO BE SOLVED: To provide a small-power communication device, by which a communication apparatus is miniaturized and manufacturing cost is reduced. SOLUTION: In a master apparatus 10, the field strength of a slave apparatus received by an antenna section 11 is measured in a measuring circuit 13, a slave apparatus 20 having a maximum field strength is detected in a control section 14, and a password data transmitted from the slave apparatus 20 is received. The received password data is compared with a reference password data stored in a reference storage section 15, and the password data is registered in a registration section 16 when they match. Thus, the slave apparatus 20 registered in the master apparatus 10 can be radio-communicated with the master apparatus 10. Since a keyboard for inputting a password, which has been used in registration is dispensed with, the communication apparatus such as the master apparatus 10, the slave apparatus 20 or the like can be miniaturized, and the manufacturing cost of the communication apparatus can be reduced. Since field strength is measured and the slave apparatus having maximum field strength is registered, other slave apparatuses will not be registered by mistake.

Next, the internal configuration of the slave unit 20 will be described. The slave unit 20 includes an antenna unit 21, a wireless circuit 22,
It comprises a measurement circuit 23, a control unit 24, a password storage unit 25, and a registration unit 26. The antenna unit 21 is an antenna for transmitting password data and transmitting and receiving various data to the antenna unit 11 of the base unit 10. The wireless circuit 22 changes the password data transmitted by the antenna unit 21 into a signal to be radiated by the antenna. Of course, when data is received from the antenna unit 21, the data is transmitted to the measurement circuit 13 in the subsequent stage.

In this case, child device 20 is closer to parent device 10 than child device 29 that is not registered. Then, the master unit 10 receives the electric field strength of the antenna unit of the slave unit (step 1), and the measuring circuit 13 outputs the maximum electric field strength of the received electric field strength to the control unit 14. Here, FIG. 3A shows the state of the electric field strength received in step 1. The child device 20 is a parent device 1 more than the child device 29.
Since it is close to 0, the electric field strength of the slave 20 has a higher value than the electric field strength of the slave 29. Therefore, the measurement circuit 13

In step 4, if the password data does not match the reference password data, the registration process ends, and if they match, the process proceeds to the next step. If the password data and the reference password match, the password data of the child device 20 is registered in the registration unit 16 (step 5), and the parent device 1
Registration of the child device 20 with 0 is completed.

Therefore, it is not necessary for both the master unit 10 and the slave unit 20 to have a keyboard for inputting a password used for registration. Cost reduction is possible. In addition, since the communication device (slave device) having the largest electric field strength is registered by measuring the electric field strength, another communication device (slave device 29) is not erroneously registered.
