Description

{System for remote failure diagnosis and monitoring empolying building power-saving system empolying Long Term Evolution network}

The content disclosed in this specification relates to a technology for remotely monitoring and controlling a building power saving system, and more particularly, when performing such remote monitoring and control, the central control center remotely monitors and controls the building power saving system through an LTE network. It's about technology.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

In general, a building power saving system monitors and controls power consumed by power devices installed in homes, buildings, and city facilities.

Such a building power saving system includes a central control unit that monitors and controls the power consumed by a plurality of power devices, a power control unit that controls the power of a plurality of power devices, a sensing unit that detects the environment around the power device, and information collected by the sensing unit and a transmitting unit which transmits to the central control unit and transmits a control signal provided from the central control unit to the power control unit.

At this time, the application service program may be provided to all users in bulk.

However, it is generally provided variably according to the characteristics and needs of the user.

On the other hand, in relation to a building power saving system, for example, an emergency state information transmission method is divided into an RS-232 method for transmitting power status information in a packet form and an Ethernet method using SNMP (Simple Network Management Protocol).

Among these methods, the RS-232 method is a half-duplex communication method that has a short communication distance and is mainly used for 1:1 communication.

This is a condition that can only be achieved by converting in this way.

In addition, the Ethernet method using SNMP has a problem in that it cannot provide an information transmission system that perfectly meets the various needs of consumers and business operators because various configurations are possible with a network switch in the premises, but it is a construction method that necessarily requires the laying of network cables.

In addition, the existing wired network network method, which configures a physical network to configure a separate SMS module to receive messages for simple alarms, is exposed to external hacking, which can cause fatal flaws in security. In addition, the method of real-time control of data in the control room or the operator's PC has limitations on monitoring/management in terms of time and location.

In addition, each mobile carrier currently has a dedicated IoT network as of the end of 2016.

In addition, there is a need for a manager to monitor real-time power status information in real-time even in indoor facilities where separate network construction is impossible or in areas where long-distance remote monitoring is required.

Meanwhile, the configuration of the PLC controller 103 applied to the building power saving system 100 of FIG. 3 described above will be described in more detail herein.

First of all, additional explanation in this regard requires modules with various functions for existing PLC systems used in various environments, and accordingly, PLC manufacturers provide various modules that satisfy user requirements. For example, a module having various functions, such as a digital input/output module, an analog input/output module, and a communication module, is used in a PLC system, and a system desired by a user is built through these various modules.

For example, the technology of Patent Document KR101778333 Y1 is an invention registered as such a technology, and specifically relates to a PLC system having a diagnostic module for diagnosing whether an output module of the PLC is defective in operation.

The above-described IOT module according to an embodiment uses these points to provide a PLC that provides an IOT function from the IOT module, so that monitoring and control can be easily performed by an administrator.

Accordingly, according to an embodiment, the PLC controller 103 outputs a control signal to an input module receiving a signal from the 1-2 sensor unit 101-102, a CPU module serving as a central control unit, and a control target. Includes output module.

In addition, the PLC controller 103 includes an IOT module that additionally performs an IOT function in the PLC itself, so that the CPU module interworks with the input/output module by such an IOT module to provide an IOT function from the corresponding control logic.

For reference, here, the input module of the PLC controller 103, that is, the A/D module and the D/I module, includes various analog and digital information is input in an integrated way.

For example, the input module receives analog information on fine dust around the building from the second sensor unit 102 , for example, a fine dust sensor. Alternatively, the second sensor unit 102 through the D/I module, for example, receives the sunlight information around the building as digital information.

In this case, the input module is defined as including an I/O card as an input module of the PLC.

And, the output module of the PLC controller 103 is a control target when a signal is input through the input module and a control signal is generated by the CPU module, for example, a fine dust reduction device installed in a building. transmit a signal

In addition to this, the IOT module performs the IOT function in the PLC itself in this case according to an embodiment.

Specifically, the IoT module has its own TTS engine, and the TTS engine provides voice information corresponding to the level of the surrounding environment state of the building by the second sensor unit 102 directly.

Also, as another example, the IoT module receives an external voice related to power saving of a building, performs noise cancellation, and outputs audio.

In addition, the IoT module makes a voice alarm to the central control center 200 with the voice information corresponding to the level of the surrounding environment of the building by the second sensor unit 102 as IoT data.

In this case, the voice message is registered, for example, in a flash voice memory provided in the IOT module itself.

So, through this, the data collected from the PLC's I/O card is alarmed with a designated voice.

In addition, the PLC controller 103 performs a noise canceling function for an external voice.

Specifically, the IOT module performs an audio IOT function by receiving a voice of a manager related to power saving of a building, performing noise cancellation, and outputting audio.

For example, in this case, an audio IOT function is performed by receiving an external audio input, performing noise cancellation, and outputting audio through an audio amplifier provided in the IOT module itself.

Then, the central control center 200 receives the power saving state information of the building from the IoT module of the PLC controller 103 and compares it with preset reference power saving state information to check whether the building power saving system has a failure.

4 is a flowchart sequentially illustrating the operation of a remote fault diagnosis and monitoring system of a building power saving system using an LTE network according to an embodiment (refer to FIG. 2 ).

As shown in Figure 4, the remote fault diagnosis and monitoring system of the building power saving system using the LTE network of an embodiment is first installed in each building, and the building power saving system is installed in each building to detect the electricity consumption of each building (S401). By notifying the central control center registered in advance by the LTE network (PLC-based IoT-type LTE network) according to the example (S402), the administrator is informed of the current state of electricity use in the building.

And, in the system according to an embodiment, the central control center receives a notification of the building's electricity consumption for each building power saving system, calculates the electricity usage status of each building for different time zones or seasons (S403), and a corresponding power saving control signal to control the power saving operation of each building through the LTE network (S404).

Therefore, through this, the system of one embodiment performs remote monitoring of the building power saving system, by monitoring the electricity usage status of each building by the LTE network by time zone or by season by the central control center, remote power saving of each building power saving system Control.

On the other hand, in addition to this, the building power saving system detects the surrounding environment state of each building at this time (S405) and notifies the central control center through the LTE network (S406), thereby notifying the manager of the surrounding environment status of the building.

And, in the system, the central control center receives notification of the surrounding environment state of the building for each building power saving system, and compares the surrounding environment condition of each building with a preset reference environment condition for each different time period or season, for example. By calculating for each different surrounding environment, for example, fine dust, temperature, and humidity (S407), and providing it to each building power saving system through the LTE network, the surrounding environment of each building is controlled (S408).

Accordingly, when the system of one embodiment remotely monitors the building power saving system, the central control center can remotely monitor the electricity use of each building or the surrounding environment of the building by time zone or season by the LTE network according to the embodiment. monitor and control.

As described above, in one embodiment, the building power saving system installed in each building detects the electricity consumption of each building or the surrounding environment state of each building, and transmits the electricity usage information of each building or the surrounding environment state of each building to the central control center. By providing wirelessly by LTE network (PLC-based IoT-type LTE network), it informs the building's electricity consumption and surrounding environment status easily and quickly.

Therefore, in one embodiment, when remote monitoring of the building power saving system, the central control center remotely monitors and controls the state of electricity use of each building or the state of the surrounding environment of the building by time zone or season by LTE network, which is a mobile communication network. do.

5 is a diagram for explaining an operation of notifying a building electricity consumption or a building surrounding environment state of a remote fault diagnosis and monitoring system of a building power saving system using an LTE network according to an embodiment.

As shown in FIG. 5 , the system of one embodiment is a PLC controller when the building power saving system 100 detects the electricity consumption of the building and the surrounding environment state of the building by the 1-2 sensor units 101-102. By notifying the detection result from the IoT module of 103 to a pre-registered manager terminal (eg, smart phone) app, the manager easily and quickly grasps the electricity consumption of the building.

For example, the CPU module of the PLC controller 103 is connected to the manager terminal 300 with an individual IP address of the corresponding wireless communication network when the previously registered administrator terminal 300 is connected to the wireless communication network, and the wireless communication network is connected. If not, the terminal identification number of the mobile communication data network is connected to the manager terminal 300 to secure a real-time connection with the manager terminal 300 .

So, the CPU module of the PLC controller 103 transmits the electricity usage amount and the surrounding environment information of the building sensed by the 1-2 sensor unit 101-102 to the manager terminal 300 by the IoT module. do.

As another example, in the system according to an embodiment, the CPU module of the PLC controller 103 determines the surrounding environment state of the building by the second sensor unit 102, for example, a preset reference value for each different time period or season. When an abnormal state is determined by comparing the environmental state and the different surrounding environments, the IoT module notifies the manager terminal app.

For example, when the fine dust concentration of the building by the fine dust sensor exceeds the preset reference fine dust concentration, the CPU module of the PLC controller 103 determines an abnormal state and notifies the manager terminal app by the IoT module do.

6 is a view showing a user interface screen related to the condition of the surrounding environment of the building of the remote fault diagnosis and monitoring system of the building power saving system using the LTE network according to an embodiment.

As shown in FIG. 6 , in the system according to an embodiment, when the building power saving system, for example, when fine dust information of a building is input, the camera image (used as a background image here) and the fine dust monitoring result are mutually By interworking with the user interface, the central control center or the manager terminal measures the fine dust information and the like with video.

For example, when fine dust information is input, the system according to an embodiment interlocks the camera image, fine dust state information such as fine dust amount and goodness, and text, graph, coordinates, etc. By converting it into an image, it measures the image including fine dust information.

Here, it is an example of notifying ‘Air cleanliness in the premises is abnormal!’ and ‘2nd floor’, which is area information.

So, the system of one embodiment provides such an abnormal state, ie, the surrounding environment of the building, to the manager in an image from the central control center or the manager terminal.

To this end, the building power saving system according to the embodiment includes a camera module for photographing the surrounding environment of the building, and a DSP unit that digitally processes the captured image of the surrounding environment of the building and transmits it to the PLC controller .

And, in addition to this, the PLC controller according to an embodiment includes an HMI module.

At this time, the IoT module of the PLC controller provides the above-described abnormal state UI information as IoT data to the central control center or the manager terminal through an LTE network or the like.

In addition, the HMI module pops up a map in the form of a map based on the HMI when there are a plurality of images captured including the camera module.

Additionally, the remote fault diagnosis and monitoring system of the building power saving system using the LTE network according to an embodiment performs authentication of the building power saving system to which the IoT is applied so that broadcasting can be selectively performed.

To this end, in the remote failure diagnosis and monitoring system of a building power saving system using an LTE network according to an embodiment, a location-based authentication system for an IoT network is a cell through an evolved Multimedia Broadcast Multicast Service (eMBMS). A seed code is transmitted to an internal IoT (Cellular internet of things) terminal. A seed code is a basic code used in a terminal encryption algorithm generally used in a location-based authentication encryption system and the like. In an embodiment, the seed code may be implemented in various ways, such as symmetric key exchange, asymmetric key exchange, symmetric key encryption, asymmetric key encryption, and the like. The selective encryption apparatus and method are not limited to a specific encryption algorithm method, and the seed code may be secured in various ways.

The eMBMS (evolved Multimedia Broadcast Multicast Service) system is an LTE-based video transmission service supporting one-to-many.

In such a location-based authentication system, a building power saving system to which the IoT is applied receives, for example, a temporary terminal group ID requested from the SCEF, and allocates it to the IoT-applied building power saving system that controls various home appliances in the IoT network. The seed code for generating location-based authentication passwords is sent to the building power saving system. In an embodiment, the IoT building power saving system may collect the user's biometric information and location information with a sensor and a camera provided in the terminal, and may generate a terminal authentication password using the collected information through a pre-installed password generation algorithm. Specifically, the user's biometric information and location information are combined to generate a terminal version location-based biometric authentication password, and it is transmitted to the location-based authentication server to perform IoT building power saving system authentication before receiving the seed code.

Therefore, through this, the IoT building power saving system and the location authentication server generate a password combining biometric information and location information and transmit the seed code after terminal authentication through this, thereby further improving security in the IoT network.

Additionally, the remote fault diagnosis and monitoring system of the building power saving system using the LTE network according to an embodiment is different from the above-described PLC, and an external input/output port, that is, a digital input (Digital Input), a digital output (Digital Output), Provides a video monitoring system that can handle analog input (Analoge Input: 4-20mA input, etc.) make it possible

To this end, the remote fault diagnosis and monitoring system of a building power saving system using an LTE network according to an embodiment includes a data collection unit that receives analog data and digital data from an external measuring device, respectively, and a commercial CPU accordingly.

The data collection unit includes an ADC converter that converts a signal of an analog sensor into a digital signal, a GPIO port for receiving an electrical input or output to control an external sensor by interworking with viewer software, and digital data from the external measuring device.
