  The present invention relates to an indoor monitoring sensor / network system, and more particularly, to connect a plurality of monitoring sensors arranged indoors such as a general house so that they can communicate with each other via a wireless network and transmit detection / monitoring data to a required contact. The present invention relates to a suitable indoor monitoring sensor network system.

  In recent years, the importance of countermeasures for the safety of the lives of indoor residents has increased along with the increase in the occurrence of fires in houses and houses and the increase in crimes in indoors such as general private houses. Therefore, for example, as a monitoring sensor for preventing a fire, conventionally, a fire alarm that can be easily connected to a large number of power outlets provided on an indoor wall or a power connector for lighting equipment provided on a ceiling is used. A vessel (Patent Document 1) has been proposed.

  However, when a large number of monitoring sensors of the same type or various types are deployed indoors such as a private house, problems related to the notification destination or contact information of the abnormal state detected by the monitoring sensor, or the situation detected by the monitoring sensor Information management issues are raised. For example, when there is a resident in a place close to the site of the indoor fire, the person himself / herself will know the abnormal state related to the fire by the alarm of the fire monitoring sensor, but the resident is absent. When you are away, or when you are away, the big problem is where to communicate such emergency abnormal conditions.

From the viewpoint of the above problem, an information network system in a private house has been proposed as a related prior art (Patent Document 2). This information network system is merely a proposal of a wired network system configured to perform wiring indoors using a lighting power supply outlet of a private house or the like.
