Description

IOT-based local management system {SYSTEM FOR LOCAL MANAGING BASED ON INTERNET OF THINGS}

The present invention relates to a local management system based on the Internet of Things (IoT).

In general, the Internet of Things (hereinafter referred to as'IoT') is an Internet that is more advanced than the existing wired communication-based Internet and mobile Internet, and is a sensing technology that obtains information from objects and surrounding environments used in daily life. It is an intelligent technology and service that is combined to communicate information between people and things or between things and things.

Meanwhile, according to the transformation of communication technology, in the early wired communication era, data exchange occurred only through the connection between objects such as personal computers (PC), requiring human intervention as a medium, but due to the gradual development of wireless communication technology. The range of communication between people and people, people and things, and things and things has been expanded, and furthermore, it has evolved into M2M, which enables autonomous communication between objects.

With the evolution of this IoT technology, various devices (eg, CCTV systems or communication network related equipment) are being converted into IoT devices, and IoT devices are connected to each other through various network methods to establish an Internet network.

In addition, a number of IoT devices constituting a communication network may perform specific tasks through external communication through a network connection in addition to running software and hardware at a local end, that is, each IoT device end.

On the other hand, in the communication network, normal connection may not be established due to malfunctions such as noise of signals transmitted through the communication channel, problems on the communication channel, or power supply of the corresponding IoT device.

However, when a corresponding IoT device is always connected to a communication network to provide normal power supply and/or communication, the above-described network communication interruption and/or power failure may be inconvenient or fatal.

Therefore, the administrator must always check the network connection status and/or power supply status of the IoT device, and quickly recover it when the network connection connection and/or power supply is unstable or disconnected.

At this time, when a communication network and/or power supply failure occurs, the first thing managers do is to find out what point and what point. However, for ordinary administrators, it is almost impossible to find out which point of the handicapped person is, so the network communication equipment is rebooted in the easiest and most accurate way.

Therefore, in recent years, the administrator has to always check the connection status and/or power supply status of the communication network to each IoT device, and in the event of a failure, the hassle of having to turn on/off the power of the network communication device individually. In order to solve this problem, a local management system that always checks the connection status and/or power supply status of the communication network to each IoT device, and can quickly recover from problems in the communication network connection and/or power supply is urgently needed. have.

The resistive humidity sensor measures humidity by using a change in resistance changed by humidity. This resistive humidity sensor has been used a lot because it is relatively cost competitive compared to the capacitive humidity sensor.

However, in recent years, as the capacitive humidity sensor can be manufactured in a one-chip form on a semiconductor substrate, it is possible to secure an advantage in price competitiveness compared to the resistive humidity sensor, and the use thereof is increasing. In particular, the capacitive humidity sensor has the advantage of having superior reliability compared to the resistive humidity sensor, but having a linear sensor characteristic and less influence of temperature.

Such a capacitive humidity sensor is a sensor using the principle that the capacitance changes according to the molecular weight of water adsorbed on the moisture-sensitive film. When moisture is absorbed, a moisture-sensitive material such as polyimide or ceramic that changes dielectric constant is used. It operates in the form of a capacitor made of a dielectric. That is, there is a moisture-sensitive layer that senses humidity, and it is a principle of detecting that the dielectric constant changes as moisture flows through the moisture-sensitive layer, and the capacitance changes accordingly.
