The first covering is made of an insulator and can prevent power loss and short circuit. Additionally, it can be formed as a flame retardant to prevent flames from occurring. However, since it conducts heat, it can transfer heat to the heating object (P) of the building. Since the first and second coating materials use a flexible material such as rubber, they enable deformation. In other words, it makes it possible to wrap it around a structure such as a pipe. The heating wire and temperature sensor of the present invention enable integration. In other words, by forming the heating wire and temperature sensor into one body, work efficiency can be improved.

(Example 5-4) The present invention relates to a heating wire device for preventing freezes and bursts. In Example 5-2, the node includes a thermoster and a thermocouple.

(Example 5-5) The present invention relates to a heating wire device for preventing freezes and bursts. In Example 5-2, the nodes have the same shape and are formed in an uneven shape spaced a certain distance apart.

The present invention (Examples 5-1 to 5-5) embodies a temperature sensor. Conventional inventions measured temperature using thermosters and thermocouples. They can measure the temperature at a designated point. In other words, when measuring temperature at multiple locations, there is a disadvantage of having to install multiple temperature sensors. However, since the present invention measures the amount of heat generated for the entire section of the sensor itself, the temperature of the line and surface can be measured. Specifically, a sheet (deformable plate) of flexible material is formed as a base plate, and the deformed plate is formed as thin as possible and is made of a material with a high coefficient of linear expansion. In other words, as much deformation as possible is generated by external heat. There is a node at the top of the deformed plate. A sensor current is passed through the node, and the electrical resistance value changes due to deformation of the deformable plate. In other words, as the amount of deformation increases, the resistance value increases. A first connection line and a second connection line are connected to both ends of the node, and current is passed through the sensor. Each of the first and second connection lines may provide information to the controller through the first and second terminals. When an external current is applied to a node, it causes error information. Therefore, the nodes and the first and second connection lines must be coated with a second coating, and the second coating must be formed of an insulating material. The nodes are arranged in a plurality of grids to enable surface detection. The nodes have a concavo-convex joint structure and are kept at a constant distance from each other. Additionally, the nodes are located on the conductive layer plane. Therefore, it is possible to provide a change in resistance according to sensitive deformation.

The present invention (Example 6-1) provides a technology to recognize the operating state of the controller from the outside and, if necessary, remotely control the operation of the controller from the outside. To implement this, a communication module must be installed in the controller. The communication module sends signals from the controller to the outside. The transmitted signal transmits the device's unique number, temperature information, operation information, and leakage information. The control center's server measures each signal from each controller and verifies normal and abnormal conditions in real time using the measured signals. When an abnormal state occurs by the server, the purpose is to deliver related information to the administrator. In addition, the administrator can check multiple controllers at once through his or her terminal and check warnings in real time. As another embodiment, the operation of the controller may be controlled by a server and a terminal. In other words, remote operation is possible. The server receives information in real time from multiple controllers, the input information is stored as big data, and operation signals according to operating status are also stored.
