Hereinafter, operation characteristics of the small remote multi-control apparatus according to an embodiment of the present invention will be described in more detail with reference to FIG. 5 through FIG.

FIG. 5 is a diagram illustrating a camera control operation through traffic analysis of a small remote multi-control apparatus according to an exemplary embodiment of the present invention. FIG. 6 is a flowchart illustrating an image analysis of a small remote multi-control apparatus according to an exemplary embodiment of the present invention. FIG. 7 is a diagram illustrating a computer control operation through analysis of serial data of a small remote multi-control apparatus according to an embodiment of the present invention. FIG. 9 is a diagram for explaining an overload detection operation of the small remote control device according to an embodiment of the present invention.

First, a process of installing a small remote multi-control device will be described. In the power source section, a power cord is plugged into a power input terminal to supply power to a small remote multi-control device. Each terminal code that requires power control is connected to the power terminal block.

In the communication unit, the short-range communication terminal is composed of an RS232 communication connection, and receives data for controlling AC power from the computer. It also enables current temperature measurement. The long-range communication terminal is composed of RS485 communication connection. Bypass the data coming in via RS232 communication and transfer it to the camera.

Also, when the contact signal is received, the sensor connection terminal receives the contact signal from the non-contact contact sensor or the like, and transmits the determined data to the computer through the RS232 communication. For example, when a loop detector for detecting the passing of a vehicle is used as a contact sensor and is connected to a sensor connection terminal, if the loop detector is operated, the character 'L' is transmitted to the computer via RS232 communication. The LAN connector receives data from the router to control AC power.

Referring to FIG. 5, an example of using an IP camera as a camera is shown. First, video data is transmitted to a server to store an image captured by an IP camera. At this time, since the video data is continuously transmitted, it always causes traffic exceeding a fixed value. Especially, in the case of HD video, data of 3 ~ 4 megas per second is stored.

If the traffic of the IP camera drops below a certain value, it means that the image is not transmitted properly. If traffic reduction is detected for more than a certain time (about 5 minutes) while analyzing the traffic by monitoring the traffic of the IP camera through the small remote multi-control device, it is determined that the IP camera is abnormal, And turns it on via the remote multi control unit.

Referring to FIG. 6, there is an insufficient part for checking whether there is an abnormality in the IP camera by only analyzing the traffic, as another method for detecting the abnormality of the camera. For example, if the transmitter part of the camera operates normally and sends certain data but there is a problem in the part where the image is taken, if there is an external factor such as a lens, Analysis is required.

 Therefore, the IP camera operates normally but the non-normal screen is transmitted due to the camera lens or other factors. In this case, most of the images transmitted from the IP camera are composed of monochromatic colors.

If the above phenomenon is detected for a predetermined time while analyzing the image of the IP camera through the small remote multi-control device, it is determined that the IP camera is abnormal and the power of the IP camera is turned off through the small remote multi-control device .

On the other hand, when it is judged that there is an abnormality of the camera through traffic analysis and image analysis, if the abnormal phenomenon is repeated 3 or more times in succession, an abnormal alarm is displayed in the control room and power control is performed until a special action is taken in the control room Pause. That is, by preventing the camera from being damaged by repeated power on / off, and informing the control room of the camera, another fundamental problem of malfunction can be solved.

Referring to FIG. 7, a compact remote control device and a computer are connected by a serial communication (RS232) in order to detect whether the computer is alive or not. The small remote multi-control device and the computer communicate periodically (1 second) through specific data to check whether the computer is operating normally. As described above, if there is not more than 60 consecutive times of data being returned from the computer while transmitting / receiving specific data, the computer is detected as abnormal and turned off after turning off the computer.

On the other hand, even in the case of a computer, if an abnormality is repeated three times or more while judging whether or not the computer is abnormal through transmission / reception of serial data, an abnormal alarm is displayed in the control room, Suspend control. That is, it prevents damage to the computer by repeated power on / off, and informs the control room of the damage, thereby solving another fundamental problem of malfunction.

Referring to FIG. 8, in order to detect whether the router is alive or not, a small remote multi-control device performs a ping test on the router and returns a result value. If data such as no response and no normal packet value is returned during the ping test, it is determined that the router is abnormal and the power of the router is turned off and then turned on.

On the other hand, in case of the router, if it is judged that there is an abnormality, if the abnormal phenomenon is repeated three or more times in succession, the abnormal alarm is issued to the control room and the power control is temporarily suspended until a special action is taken in the control room. In this case, the router is a device for data communication to the control room. In this case, the LTE module is attached to the small remote multi-control device and an alarm is sent to the control room in this case because the router may not transmit an abnormality detection alarm to the control room due to a malfunction of the router give.

Referring to FIG. 9, in order to perform power measurement and overload detection of the controlled devices, the power amount of loads of the controlled devices that are subordinate to the small remote multi-control device is detected in real time and data is transmitted.

In particular, when the overload of a specific port is detected for a certain period of time (1 minute) while detecting the power amount, it is determined that the load is abnormal and an alarm is issued to the control room.

<Other Embodiments>

The small-sized multi-control apparatus according to another embodiment of the present invention can be used even in the pressure field of the water supply system. Specifically, it is possible to automatically recover the communication trouble (the router problem and the floating IP) between the control program installed at the central control center and the PLC and the electric panel of the unmanned pneumatic press. That is, it is possible to reset the router with the function of detecting whether or not the router is abnormal.

In addition, when the water is pumped to the pressure pump by the timer setting, the power of the pump can be turned off to prepare for pump failure. That is, when water enters the pump, the power can be turned off and the power can be applied after a certain period of time to reduce the pump failure.

Also, the temperature can be measured and data can be transferred to the pneumatic control room and the control room. That is, it is possible to check the temperature and humidity remotely, and when the fan cooler is connected to the contact point, the fan can be driven at a predetermined temperature or higher to reduce the energy consumption.

In addition, if the distance between the situation room computer and the pressure field is less than 1 Km, it is possible to periodically transmit data to the control room by determining whether or not there is a computer abnormality with the protocol data. Furthermore, it is possible to detect when a contact point is given by the water level sensing device.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the present invention should be construed as being included within the scope of the present invention.
