Description

  The present invention relates to a lost item search device, and more particularly to a lost item search device that can easily search for items that are used in daily life and are easily lost.

  An aging society has emerged due to the long life and the extension of the average life. In such an aging society, many elderly people live daily at home or in nursing homes, but in particular, a decline in memory and intelligence associated with aging becomes a problem. In extreme cases, dementia may occur, making it difficult to identify and identify things.

Such an elderly person loses various things in daily life. For example, a channel selection commander, a spectacle case, a denture case, a wallet, a card compartment and the like used when watching a broadcast by a television receiver tend to be lost. If these items are lost, the elderly person, his / her family, or a caregiver at a care facility must search for the lost items. However, the search for lost items by the elderly whose intelligence has declined is very troublesome. Therefore, searching for lost items is a heavy burden for families and caregivers around the elderly. Furthermore, it has become a big problem in the shortage of human resources at nursing homes.

  Next, the operation of the base unit 17 will be described with reference to FIG. When the key of the input operation unit 29 of the base unit 17 is operated, the MPU 22 generates a code corresponding to the transmission signal, and this code is converted into communication data. Then, transmission data is generated by adding the object of search or the identification code of the slave unit corresponding to the object to the communication data. Such transmission data is transmitted to the Bluetooth core module 33 of the Bluetooth module shown in FIG.

  In contrast, when the core module 33 receives data from one of the plurality of slave units 18 via the antenna 34, the base unit 17 removes the header and the identification signal from the received data. To retrieve the received data. Then, code analysis is performed by decoding the received data, and the contents of the received signal are extracted. Then, the MPU 22 performs a predetermined display on the display unit 30 in accordance with the contents of such a signal. Such a display is, for example, a display indicating whether a corresponding signal has been received from a target search object or a display indicating whether a corresponding article has been found.

  Next, the operation of the slave unit 18 will be described with reference to FIG. When the Bluetooth module of the child device 18 receives a signal from the parent device 17 via the antenna 54, the identification information and the header are removed from the signal, and the decoded information is converted into a code. Then, such a code is analyzed, and the contents of the transmitted information are analyzed. Then, the MPU 42 constituting the one-chip microcomputer determines whether or not it matches the identification information of the slave unit from the above code, and if it matches, performs processing according to the contents of the signal. . In general, in the case of a search operation, the slave unit 18 to which a corresponding identification code is assigned operates the electronic buzzer 49 in accordance with an instruction from the MPU 42. Further, the display LED 50 is turned on. The notification operation is performed by the operation of the electronic buzzer 49 and the lighting of the LED 50.

  Thereafter, the slave unit 18 generates a reply code, adds an identification code and a header to the reply code, and generates transmission data by the encoder. The generated transmission data is transmitted as a radio wave by the Bluetooth core module 53 via the antenna 54. Such radio waves are received by the base unit 17.

  As described above, the lost item search device of the present embodiment is widely used for television receivers and air conditioner commanders, eyeglass cases, denture cases, key holders, wallets, periodic cases, business card holders, card holders, electronic notebooks, etc. So that if these items are lost, they can be easily found.

  That is, a signal corresponding to a predetermined code is generated from the parent device 17 to the child device 18 by operating a key of the input operation unit 29 of the parent device 17 constituting the transmitter. Then, the Bluetooth module of the slave unit 18 receives this radio wave, determines the identification code added to the radio wave, and if the identification code matches, the slave unit 18 attached to the corresponding article is A notification sound is emitted. If transmission is performed without adding an identification code, all the slave units simultaneously emit a notification sound.

  Such a lost item search apparatus can be attached to various items other than the television receiver remote control and easily lost. Further, by using a flat button battery as the battery 58 for driving the power supply circuit 56 of the slave unit 18, the slave unit 18 can be made an extremely small device.
