The present invention is to prevent the fire caused by electricity, such as high-rise buildings and large buildings, the system that can check the state of the electrical wiring (leakage, On / Off, temperature, security status, etc.) at a glance on the computer screen.

Above all, in addition to the conventional current sensor in the distribution panel, by applying a temperature sensor that measures the temperature by directly contacting the wire, and by installing a separate temperature sensor for the main facilities in the building, it is located in a specific position in the wiring and wiring Information can be provided.

In addition, by using a server-client system using a network, the server transmits the status information to each user terminal, where the user can be notified to their mobile devices such as fire control offices, building managers, store owners, etc. anytime, anywhere There is an advantage to encountering status reports.

1 is a block diagram illustrating a configuration of an indoor wiring temperature sensing system according to the present invention, which includes a distribution board 1, a temperature sensor 2, a housing 3, a communication module 4, a server 5, and a user terminal 6 ) Shows the relationship between the action.

Since the components of the present invention are applied to a conventional distribution panel, it will be apparent to those skilled in the art that the processing of information provided by the conventional current sensor can be performed in parallel. May be omitted, and the following description will be mainly focused on information processing by a temperature sensor which is a characteristic component of the present invention.

The distribution board 1 is a conventional wiring system including a switch capable of interrupting power supply to each branch circuit at a point where the branch wiring is divided from the trunk line to each branch circuit in the indoor wiring. In the present invention, power supply to each branch circuit is provided. Including a switch circuit 11 that is automatically on / off according to the input signal to remotely control the to ensure that the efficiency of the initial response by the automatic off / on or remote control in a dangerous situation.

The temperature sensor 2 is a thermal conductivity (eg K-type) temperature sensor (eg K-type) because it must be in direct contact with the wire and has an insulation sensing unit 21 coated with an insulating material such as epoxy, the insulation The branch part 21 is provided so that the branch part 21 may directly contact a part of the branch circuit of the distribution panel 1 from which the covering is removed.

As the temperature sensor 2 is installed on the wire from which the cover is removed, the wire must be shielded. The temperature sensor 2 is provided with an insulating housing part 3 so that the portion from which the cover is removed is shielded.

However, the temperature sensor 2 does not necessarily need to be installed in the housing part 3, and should be configured to transmit information to the outside even when installed in the housing part 3.

The temperature sensor (2) is to be installed for each branch circuit of the distribution panel, and if additionally installed in some of the indoor wiring location can be more accurately grasp the position where the dangerous situation is detected, it is to install the temperature sensor separately in the main facilities desirable.

The communication module 4 receives the temperature information of the temperature sensor 2, amplifies it, converts it into a digital value, and sends it to a server on a network. The transmission may be continuously performed at a predetermined time interval, or may be implemented to transmit only when certain conditions are met.

The predetermined condition is when a temperature that can be determined as a dangerous situation is detected, and the communication module 4 may perform the same operation on not only temperature information but also voltage information provided by a conventional current sensor.

In addition, the communication module 4 is configured to transmit an on / off input signal for controlling the switch circuit 11 of the distribution panel 1, in this case the communication module 4 is the temperature information received from the temperature sensor Including a self-determination circuit for comparing with the set threshold value, it is possible to send an on / off signal to the switch circuit 11 of the distribution panel 1 according to the set conditions.

As a result, if it is recognized as a dangerous situation, the communication module 4 directly controls the distribution panel switch circuit 11, thereby enabling rapid initial response.

In another embodiment, the communication module 4 does not have a self-determination circuit, and merely performs a role of relaying information, and the server 5, which will be described later, may take charge of the determination and command.

The server 5 is a node on the network, which may be installed in a building or a management company, and processes and analyzes the temperature information received from the communication module 4 to design the electrical structure of the building and the temperature state of each part.

The server 5 compares the processing and the temperature information of the temperature information received from the communication module 4 or according to the command of the user terminal 6, on the switch circuit 11 of the distribution panel 1 By sending the on / off signal to the communication module 4, the distribution panel can be automatically remote controlled.

In this case, the off signal may be automatically performed, and the on signal may be implemented to be recovered after confirmation by a worker by hand.

In addition, the server 5 may classify the dangerous situation step by step through the comparative analysis with the set threshold value for the temperature information, and alert the user terminal, so that the user can determine the current situation more quickly and cope with it.

For example, <1st stage> temperature change, <2nd stage> solid line short circuit (if it melts by fire), <3rd stage> circuit breakdown (when there is no signal, etc.) It is to facilitate the situation grasping.

The server 5 may be configured to provide the user terminal with graphic information which can visually confirm the wiring position of the branch circuit indicating the abnormal temperature by mapping the temperature information on the indoor wiring diagram of the distribution panel 1.

That is, the detailed structure of the building and the indoor wiring diagram are stored in the Internet server 5 as 3D graphic information, and the received information is applied to the 3D graphic information to access the point where the problem occurs in three dimensions and to read the details. I can make contact.

The above details are data on the wiring temperature and the state of the corresponding position, and the indoor wiring diagram may be used by graphic information of the electrical wiring circuit diagram in a format that is familiar to the user.
