A communication sensor device

Abstract

The invention provides a communication sensor device which can accurately detect information related to actions of an object of sensor detection, and can carry out processing based on the information. According to the communication sensor device (100), a first antenna (1) which carries out electromagnetic transmission and reception, a second antenna (2) which carries out electromagnetic transmission and reception, a communication portion (3) which carries out data communication with a communication opposite side (52) and a sensor portion (4) which detects actions of the sensor detection object (51) are arranged in a same module (10). The first antenna is composed of an non-directional antenna, and the second antenna is composed of a directional antenna and is also provided with a transition portion (5) which can be utilized to carry out time-sharing switching of the first antenna and the second antenna. The first antenna is utilized to carry out transmission and reception used for data communication, and the second antenna is utilized to carry out transmission of sensor detection of the sensor detection object.

Description

technical field [0001] The present invention relates to a communication sensor device having both a sensor function of detecting the presence or absence of movement of a sensing object by means of radio wave reflection and a communication function of performing data communication with a communication partner. Background technique [0002] In recent years, there has been an increase in the number of households of elderly people living alone, disabled persons living alone, etc., so-called single person households. In particular, the number of elderly people living alone due to recent aging populations and smaller families has increased significantly. Therefore, in many cases, it is not possible to sufficiently confirm the safety of an elderly person living alone, and this causes problems such as slow response when an abnormality occurs. [0003] In response to such problems, technologies related to safety monitoring devices that detect the daily living conditions and abnormali...

Problems solved by technology

[0008] However, the safety monitoring device 900 disclosed in Patent Document 1 separately prepares and combines the safety notification unit 907 having the communication unit 973 and the microwave Doppler sensor 903 for distance measurement, which may lead to an increase in size and cost of the device. The problem

In addition, when the subject 910 is irradiated with microwaves, if there is an object other than the sensing object or other moving object near the bed where the subject 910 exists, the irradiation angle of the microwave is wide. In the case of , there is a possibility of erroneously detecting motions other than the subject 910 as the sensing object.

As a result, there is a risk that information on objects other than the subject 910 or other moving objects is mistakenly treated as information on whether the subject 910 is safe or not.
