Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing components of an embedded type smart IOT device 1 for sensing a load device in a building according to the present invention, and FIG. 2 is a block diagram showing components of an embedded smart IOT device 1 for sensing a load device in a building according to the present invention. FIG. 1 is a perspective view showing components of the device 1, which is detachably connected to one side of an input / output terminal of a load device in a building, and senses temperature, acceleration and load current of the load device, The system is configured to transmit the sensing data and the fault diagnosis data in real time to the central management server located at the remote location by analyzing the data on the site by self diagnosis.

More specifically, the embedded smart IOT device 1 includes a main body 10, a connection connector 20, a battery 30, a smart sensing module 40, a short range communication module 50, a display module 60 ), A wire / wireless communication module 70, an embedded module 80, and an actuation module 90.

First, the main body 10 according to the present invention will be described.

The main body 10 has a rectangular box shape and serves to protect and support each device from external pressure.

As shown in FIG. 3, the smart sensing module is formed on one side of the connection connector, the short-distance communication module is formed on one side of the smart sensing module, A display module is formed on one side of the short distance communication module, a wired / wireless communication module is formed on one side of the display module, an embedded module is formed on one side of the wired / wireless communication module, and an actuation module is formed on one side of the connection connector .

The main body according to the present invention is made of a material that can protect the internal memory unit from vibration and external pressure of the load device, has a high heat radiation effect, is light, and has excellent durability and strength.

More specifically, the main body may be made of one or more resins 60 selected from ABS, polypropylene, polycarbonate, polybutylene terephthalate (PBT), polyamide (PA), polysulfone (PSU) To 80 wt%

10 to 30 wt% of at least one additive selected from the group consisting of aluminum (Alumium), graphite (Graphite), silver (Silver) and copper (Copper)

10 to 20 wt% glass fiber having a diameter (Diameter, 탆) of 16, a density of 2.58, a tensile strength (Gpa) of 1.65 and a tensile modulus (Gpa) of 77 was put into a mixer The mixture was blended at 230 to 270 ° C at 5 to 10 rpm, extruded using an extruder, and cooled at room temperature to prepare pellets having a size of 4 to 6 mm,

The pellets are injected into an injection machine and injection-molded at a processing temperature of 200 to 250 DEG C and a processing pressure of 1,200 to 1,600 psi.

More specifically,

In selecting the resin, it is preferable to use poly (butylene terephthalate). This is because PBT molded parts have excellent rigidity and low wear. For this reason, it can be used at high temperature and it is easy to improve the rigidity because it is excellent in composite effect with glass fiber.

It also has excellent electrical properties and is less affected by temperature and humidity changes. Generally, the reason why plastic is recognized as an insulator is that the molecular structure of the polymer has a long chain tangled and dispersed by the vibration transmitted by the energy in the heat transfer process, and the thermal conductivity is 0.17 ~ 0.2 W / This is because there is a characteristic.

If the amount of the resin to be used is less than 60 wt%, the moldability is deteriorated. If the amount exceeds 80 wt%, the resin may deteriorate in thermal conductivity to deteriorate the heat generation characteristics. Therefore, the amount of the resin is limited within a range of 60 to 80 wt% .

Further, graphite is preferably used in selecting additives. Graphite has a higher thermal conductivity than other additives because the molecular size of graphite is relatively small compared to other molecules, resulting in a uniform distribution during mixing.

When the amount of the additive used is less than 10 wt%, the heat radiation characteristics become poor. When the additive amount exceeds 30 wt%, the heat radiation property is enhanced, but the problem of durability such as weakening of tensile strength and the problem that moldability is deteriorated , The amount of the additive to be used is preferably limited within a range of 10 to 30 wt%.

When the amount of the glass fiber used is less than 10 wt%, the improvement of the strength is insignificant. When the amount exceeds 20 wt%, the moldability may be deteriorated. Therefore, the amount of the glass fiber is preferably limited within a range of 10 to 20 wt% .

Specific examples of the formation of the main body will be described below.

70 wt% of polybutylene terephthalate (PBT)

20 wt% of graphite,

10 wt% of glass fiber having a diameter (Diameter, 탆) of 16, a density of 2.58, a tensile strength of 1.65 and a tensile modulus of 77 was introduced into a mixer to produce 250 The mixture was extruded using an extruder and then cooled at room temperature to prepare pellets having a size of 5 mm.

The pellet is injected into an injection molding machine and injection molded at a processing temperature of 230 DEG C and a processing pressure of 1,500 psi to form a body.

In addition, the main body 10 according to the present invention is formed with a circular magnetic part on one side of the bottom surface in contact with the load device in the building, so that it is fixedly attached to the load device in the building with a small force.

The lithium polymer battery pack 31 is a battery which is connected to a plurality of lithium polymer batteries in a cell unit and is used by being charged with an external power source and used semi-permanently. This is a lithium ion battery in which a polymer electrolyte as a solid component is used instead of a lithium ion battery using a liquid electrolyte .

This is because the electrolyte is in the form of solid or gel. Therefore, even if the battery is broken due to an accident, the electrolyte is not leaked out, so there is little fear of ignition or explosion, and the stability is secured and energy efficiency is higher than that of the lithium ion battery.

In addition, there is no need to use a solid metal sheath, and it can be formed in various sizes and shapes depending on the application. It can be manufactured to a thickness of 3 mm or less and can be reduced in weight by 30% or more and the forming process is relatively easy compared to a lithium ion battery , Mass production and formation of large batteries.

Next, the smart sensing module 40 according to the present invention will be described.

In the temperature sensor according to the present invention, a 4-wire RTC circuit part is connected to one side of the output terminal to reduce the resistance error generated on the line, thereby improving the accuracy and transmitting the result to the embedded module.

The 4-wire RTC circuit section comprises a 12V reference IC, an amplifier (AMP03) element, a header connector for temperature sensor connection, a comparator U8, and an amplifier U9.

The gyro acceleration sensor 42 reads the motion sensing value using the X, Y, and Z vector values from 0 to 20 mA through the first current loop receiver and the second current loop receiver, and outputs the 0 to 5 V output.

At this time, a 24-bit high-resolution ADC IC is connected to one side of the output terminal, and the value sensed by the 3-axis gyro sensor is transmitted to the smart sensor microcomputer input terminals PA4, PA5, PA6, and PA7 through 24-bit high resolution.

The second current loop receiver reads the Y and Z vector values as a 2-channel motion sensing value in the range of 0 to 20 mA, for example, among the motion sensing values using the X, Y and Z vector values of the 3-axis gyro sensor, To the input terminal AIN1 + of the IC.

At this time, the 24-bit high-resolution ADC IC converts the 1-channel motion sensing value of the X vector value sensed by the first current loop receiver and the 2-channel motion sensing value of the Y and Z vector values sensed by the second current loop receiver into 24- To the smart sensor microcomputer input terminals PA4, PA5, PA6, and PA7.

The load current sensor 43 senses a current flowing when a load is applied to a load device in the building.

This is configured by selecting either a current transformer type current sensor or a Hall element type current sensor.

The current transformer type current sensor serves to detect a primary current by measuring a secondary current by winding the primary and secondary coils around the magnetic core using a donut-shaped magnetic core.

The Hall element type current sensor has a role of detecting the strength of the magnetic field, that is, the strength of the current, by measuring a Hall voltage by providing a Hall element in a magnetic field generated by a current.

If a load is applied to the in-building load device, the load becomes large, and the current also becomes large.

Here, for example, in the case of a transformer, an electric arc is generated by connecting a lamp to a secondary side of the transformer, or a welding machine is connected to the transformer, or an electric motor is connected to rotate the transformer.
