The hub is a device used to connect a computer using a cable. Generally, the hub is similar to a box with several connectors, in which nodes are attached and LEDs to indicate the status of each port. have.

The hub consumes less power than the existing structure and is designed in a structure capable of processing data and the like. Recently, research on reducing the power consumption of the hub itself is also being conducted.

In addition, when the hub is operated, if a data abnormality occurs in connection with data and an interface device, the operation may not be possible. Therefore, there is a problem in that the network system and the like must be reset one by one.

In addition, when the periphery of the hub is overheated, the current flowing through the device for controlling the motor speed can be blocked, and even if the periphery is not overheated, the current flowing between the hub and the device can be cut off when an overcurrent flows. There was a need for an interface module device or system that could reset the power supply.

First, referring to FIG. 1 , a switching hub 10 enables mutual communication with a computer or a network system, and has a feature that several connection ports are formed, so that data frames are exchanged with each other or can connect. In addition, when there is a large amount of communication between servers in the communication network and the servers are connected to the same hub at the same time, there is a function to improve the performance of the communication network by using it instead of a normal repeater hub.

In addition, since the switching hub has a switching function, it transmits data received to itself only to a node corresponding to a destination and does not transmit it to other nodes, so that a security problem does not occur. In addition, since it can communicate in a full-duplex mode, it has excellent transmission speed even when several nodes are connected.

In addition, the switching hub 10 is also characterized in that the Internet signal input through a UTP cable (Unshieded Twisted Pair Cable) is distributed to a plurality of distribution ports (not shown) and provided.

The central processing board 20 is integrally coupled to a CPU, an Ethernet switch, and an Ethernet physical device (PHY) in the form of a single chip to perform Ethernet data communication. A CPU in charge of managing and controlling each part, an Ethernet switch supporting multiple interfaces in connection with the CPU, and an Ethernet physical device (PHY: Ethernet Physical layer) that converts data into Ethernet physical signals to exchange data with the Ethernet switch may include. By integrating the CPU, Ethernet switch, and Ethernet physical device (PHY) having each of the above-described functions in the same board in the form of a single chip, miniaturization can be realized.

And, referring to FIG. 2 , a Power over Ethernet (PoE) 25 for supplying necessary power to the central processing board 20 through a data line (reference numerals are omitted) is included. The Power over Ethernet (PoE) 25 supports the PoE standard defined by, for example, IEEE (Electric and Electronic Communication Society) 8023, and has the effect of supplying power even in a terminal box (not shown) to which power is not connected. have. That is, it is connected to the central processing board 20 and a data line (LAN cable) to supply power to the central processing board 20 . That is, the PoE 25 also serves as a power supply module.

The interface module 30 is connected to the switching hub 10 so that at least one communicatively coupled port (not shown) performs a plurality of different network diagnosis functions.

In addition, when abnormal power is detected in the entire network, the interface module 30 immediately notifies the network server 60 to automatically reset the power through the network server 60 to automatically restore the power. When abnormal power is generated or data abnormality is detected due to the above functions, there is an advantage in that the administrator does not have to manually reset the power by turning the power on and off one by one.

Hereinafter, a method of resetting the power source will be described with accompanying drawings.

Referring to FIG. 3A , the network server 60 receives and stores data such as fault diagnosis from the interface module 30 according to a preset program, and an interface module having a function of automatically recovering a power control signal when an abnormality occurs as a result of self-analysis It is transmitted to (30) to control the power to be reset.

In addition, the network server 60 receives the status information of each component through the network communication network and transmits/receives a power control signal to the transmission/reception module 64, and a fault determination module 63 for determining whether a failure occurs through the status information , when it is determined that a failure has occurred through the failure determination module 63, the server control unit 61 that transmits a power control signal to reset the power to the interface module 30, failure diagnosis that stores data about the failure area and symptoms It may be configured to include a DB 65 and a data storage DB 66 for storing camera images.

When it is determined that an abnormality has occurred based on the ping signal received from the interface module 30, the failure determination module 63 controls the server control unit 61 to take action on the corresponding IP, that is, to reset the power. By sending a signal to the interface module 30, the entire network can be restarted.

Here, the PING is a basic Internet program that checks whether a specific Internet address exists and whether the address can accept a request. is used as For example, if a user cannot ping a certain device (that is, if the response to the ping is not normal), it can be judged as a fault diagnosis.

In addition, in order to be able to check the faulty part in more detail in the network server 60, the data on the corresponding faulty part and symptoms for each IP stored in the fault diagnosis DB 65 is stored and then stored in the data storage DB 66. If necessary, it can be stored and read and compared with the data of the failure diagnosis DB 65 so that an accurate failure phenomenon can be identified.

The server control unit 61 can determine that a failure has not occurred when the entire network operates normally through the first signal, and the control device operates normally after one or more repeated attempts, or the control device does not operate normally after one or more repeated attempts. Otherwise, it can be judged that there is a failure.

In addition, the network server 60 may be configured to store applications related to remote control in the user authentication unit 62 and install the corresponding program.

Also, the network server 60 may be configured in the following manner.

Referring to FIG. 3B , the failure diagnosis DB 65 of the network server 60 receives a signal input via the data line of FIG. 1 through the transmission/reception module 64, and monitors the network state to cause an error such as an abnormal signal. Diagnose whether or not

Then, when a failure is detected, the failure determination module 63 notifies the server control unit 61 of the network server 60 to execute the automatic search according to the failure type.

When the occurrence of a failure is detected, the server control unit 61 notifies the occurrence of the failure and performs automatic recovery according to the type of failure. As an automatic recovery method, a Re-Link command is generated to retry the connection, and if the failure is not recovered even by the re-linking, a software reset signal or a hardware reset signal is generated.

As shown, the reset unit 67 receives the reset signal output from the server control unit 61 and resets it.

The control module 50 is communicatively coupled to the interface module 30 , and serves to coordinate the transmission of data between the interface modules 30 .

The control module 50 coordinates data transfer between the interface module 30 and memories (not shown). The control module 50 converts data received from the interface module 30 into a format that can be processed by the programmable logic modules 40 .

In addition, the control module 50 may be compatible with data received from the programmable logic module 40 and transmitted via a computer system bus (eg, a PCI bus) that communicatively couples the interface module 30 . It can be converted to a format with

Based on the received data (eg, appropriate addressing information), the control module 50 may also identify the programmable logic module 40 associated with the received data. Accordingly, the control module 50 may transmit at least a portion of the received data (eg, computer-executable instructions, computer-interpretable instructions, or circuit design) to the associated programmable logic module 40 .

As described above, the network server 60 transmits data instructing the operation of the corresponding device or devices, and receives a signal from the interface module 30 to automatically restore power.

In addition, the network server 60 stores information such as operation details of the device or device in a database, and stores the information in an emergency situation or device or device through a wireless terminal (not shown) via the Internet network and network network. It transmits a notification message to be notified of whether the operation is performed, and may receive a device or device operation command through the wireless terminal and instruct each device or device to perform the operation command.

The gateway 70, which is a communication device that provides interconnection between two completely different networks using different communication protocols, transmits and receives data between the network server 60 and the interface module 30, It serves to receive an operation command from the network server 60 and transmit it to a corresponding device or device (not shown). That is, different types of networks are connected so that information can be exchanged.

In addition, the gateway 70 may provide a monitor that can check the processed data according to the network information from the network server 60 and the stored data accordingly, and select a device connected to the network server 60 . You can also make environment settings. In addition, data is transmitted and received between the network server 60 and the sensor module 80 .

To this end, the gateway 70 receives the sensing value from the sensor module 80 through RS-485 (serial communication) communication or power line communication (PLC), and transmits the setting information received from the network server 60 . received and transferred to the sensor module 80 .

In addition, the gateway 70 is composed of the network server 60 and an external network, so that it receives an operation command signal of the device or device from the network server 60 and transmits it to the corresponding device or device.

The device or device is a device that receives an operation command from the network server 60 and operates or stops according to it, and is an electric device such as a light operated according to the sensing value of sensors (not shown) in the sensor module 80 . , CCTV, PC, Internet phone, etc.

The sensor module 80 receives information from the network server 60 and transmits the sensing values of the corresponding sensors to the network server 60 . That is, since the sensors of the sensor module 80 have a sensing function, the device or device is operated according to the sensed value.

The operation of the network interface module 30 according to the present invention of the above-described configuration is as follows.

First, power is connected to each component in the network, and each IP is registered in the network server 60 .

Power is applied to an input power source (not shown) and connected to the network server 60 through a communication network.

The server control unit 61 of the network server 60 transmits a signal to determine whether the data line is abnormal.

The server control unit 61 may determine that a failure has not occurred when the entire network is normally operated through the initial signal, and the control device operates normally after one or more repeated attempts or if the network does not operate normally after one or more repeated attempts It can be judged that there is a disability.

That is, by transmitting a signal, a component whose network state is unstable or a component that cannot communicate is determined as a failure.

When it is determined that a failure has occurred, the server control unit 61 transmits a power control signal that is a power reset signal of the corresponding IP.

The interface module 30 that has received the power control signal that is the power reset signal of the corresponding IP from the server controller 61 operates a relay (not shown) connected to the power of the corresponding IP to reset the power of the corresponding IP.

When the corresponding power is reset, the fault is recovered and normal operation is performed. As described above, when a failure or abnormal power is generated, the network server 60 records the received data and enables monitoring of the failure.

Hereinafter, an operation flow of the network interface module 30 of the present invention will be described with reference to the drawings. Descriptions overlapping with those described in the above embodiment will be omitted to some extent.

Referring to FIG. 4 , first, the administrator accesses the network server 60 and performs a network setting step ( S10 ) of setting the entire network to be operated.

That is, by setting a sensing value to be operated, a device or device corresponding to the reference value is operated.

In addition, it is set to operate a device or device through sensing and to be notified through a personal mobile terminal. In addition, the S10 generally uses a device called a router (not shown) to connect between IP networks in a network using an IP address to distinguish each computer, such as the Internet, or connect an IP network and the Internet. to do it

When this setting step (S10) is performed, the power input step (S20) in which power is supplied to the sensor module 80 is performed.

Through the above steps, each sensor of the sensor module 80 receives power and detects the corresponding

A sensor detection step (S30) of checking in real time is performed.

As the sensor detection is performed in real time, the network server 60 requests information transfer to the switching hub 10 to receive a predetermined detection value necessary for the operation of the corresponding device or device (S40) will perform

Accordingly, the switching hub 10 transmits the corresponding sensor value information to the network server 60 via the gateway 70 .

Through this, the network server 60 compares the received sensor value with the set reference value and generates a command to operate the device or device through internal calculation, and the command data is transmitted to the device through the corresponding gateway 70 . Alternatively, an operation step (S50) of operating the device is performed.

In addition, as long as power is supplied in the power input (S20) step by continuously sensing the sensors even while the device or devices are operating by the operation step (S50), the information is continuously transmitted to the network server (60). repeat the process of the method.

Here, the measurement value of the network server 60 is received through the gateway 70 together with the operation (S50) of the corresponding device or device, and can be confirmed by a monitor, and the measurement value and operation through a mobile phone (not shown), etc. You may also be notified of the situation.

In addition, the interface module 30 notifies the network server 60 of an abnormality in power flowing through the data line. Then, the network server 60 resets the power supply so that the entire network can be operated again. Since the automatic reset action of such an abnormal power supply has a positive effect on the lifespan of the network, it also has the advantage of being able to use it for a long time without failure.
