Description

[0001] The present invention relates to a smart security light controller using NB-IoT,

The present invention is a system for controlling the security light from both sides by using the NB-IoT long-range communication network, and controlling the lighting and the light off by the sunrise and sunset data. In addition, when a current sensor (CT) is attached to the security light and the detected analog value is converted to digital and the conversion information is transmitted to the management server, the management server detects the lamp failure status, relay failure status, And a smart security system capable of efficiently managing the security light by receiving the unlit state data.

Conventional security light flickers use a timer system that puts sunrise and sunset data in memory and uses the internal clock to turn on and off at that time, but it is lit during the day because the internal time is broken due to lightning or external noise, And it is replaced with GPS flasher which is improved by setting time using GPS to secure it. However, it is operated during the day due to malfunction of internal relay and defective security (lamp) , There is a problem that even if a malfunction lighting signal is turned off at night, it is turned off due to a lamp failure.

In order to perform bidirectional communication, a transmission station must be installed separately or a wired / wireless terminal must be used. In such a case, the cost of the terminal such as security increases, and the system can not be introduced due to an increase in communication costs incurred each month.

In order to solve the problems of the related art as described above, the NB-IoT (NarrowBand) which supports low-power wide area (LPWA) communication through a mobile communication network without requiring a separate transmitter -Internet of Things) wireless communication technology) to create a smart security controller that can control the security light.

In addition, it provides a real time transmission of a lamp failure and a relay failure state when the security light is turned on / off by using a current sensor (CT).

It is also intended to provide a forced control system by means of an event (when the security light is to be turned on during the day or when it is forcedly turned off at night).

Also, it provides a timer and basic data to perform the basic operation of the security lamp in case of communication failure due to a communication failure, and to provide an emergency button system so that an emergency button can be pressed.

In addition, the security light of the same unit can be grouped into one group, the collected data can be managed by mapping, and the lights can be directly checked on the management server monitor.

FIG. 1 is a block diagram of a smart security controller according to a preferred embodiment of the present invention.

Referring to FIG. 1, the MPU unit 2 and the communication unit 3 of the smart security controller of the present invention are connected by a serial communication and communicate with the serial communication unit 3 to perform mutual data transmission to the NB- . The MPU unit 2 controls the security lamp 7 in accordance with the protocol transmitted from the NB-IoT unit 1. [

The MPU unit 2 transmits and receives the light signal, the light-off signal, the event signal, the emergency signal, the light signal, the lamp failure signal, the relay failure signal, and the time data signal to / .

The NB-IoT unit 1 checks the communication state through the antenna unit 20 and maintains the optimal communication state.

The output unit 4 controls the security lamp 7 by operating the relay in accordance with the control command of the MPU unit 2. [

The current sensor unit 5 measures the amount of current flowing through the AC power source by the CT coil. When a signal to turn on the MPU unit 2 is sent to the output unit 4, the output unit 4 operates the relay. At this time, the value of the current flowing through the AC line is measured and sent to the current detection and conversion unit 6, and the transmitted analog value is converted into a digital value. At this time, when the value of the current detecting and converting section 6 is "ON" when the value of the lighting signal is "ON", the security lamp 7 is turned on and the lighting indicator lamp 16 is turned on in a normal operation state. If the value of the current detecting and converting section 6 is "OFF " when the value of the lighting signal is" ON ", the security lamp 7 is turned off due to the security lamp 7 being defective. In this case, the MPU unit 2 sends the terminal ID and the failure content (lamp failure) to the management server unit 32 via the serial communication with the NB-IoT unit 1.

7 is a data representation of the sensor measurement values. The data detected by the security lamp 7 and the current sensor unit 5 connected to the ballast 21 is sent to the current detection and conversion unit 6 and the current sensor measurement value 45 And the measured value is sent to the MPU 2 and sent to the server unit 32 of the management server and the server unit 35 of the main server unit to be used as normal and bad judgment data,

On the contrary, if the MPU unit 2 sends a signal to the output unit 4 to turn off the light, the output unit 4 does not operate the relay. At this time, the value of the current flowing through the AC line is measured and sent to the current detection and conversion unit 6, and the transmitted analog value is converted into a digital value. At this time, when the value of the light-off signal is "OFF" and the value of the current detection conversion section 6 is "OFF", the security light lamp 7 is turned off and the light-off indicator 17 is turned on in a normal operation state. If the value of the light-off signal is "OFF" and the value of the current detection conversion unit 6 is "ON", the security lamp 7 is turned on due to a relay failure driving the lamp security light 7. In this case, the MPU unit 2 sends the terminal ID and the failure content (relay failure) to the management server unit 32 via the serial communication with the NB-IoT unit 1.

In the same manner as described above, the sensor measurement values are data obtained. The data detected by the security lamp 7 and the current sensor unit 5 connected to the ballast 21 are sent to the current detection and conversion unit 6, Value 45 and sends the measured value to the MPU 2 and sends it to the management server unit 32 and the server unit 35 of the main server unit 35 to check the normal or defective in real time.

Smart security, etc. If the controller is installed for the first time, the diagnostic indicator (18) turns on normally if there is no abnormality in the self-diagnosis by inputting the value of the light on / off, emergency switch or manual switch.

When the input signal of the emergency switch 13 is detected, the switch unit 12 generates an interrupt to the MPU unit 2, the MPU unit 2 sends the signal to the NB-IoT unit 1, An alarm is displayed in the server unit (32), and a person automatically sends an SMS text to the designated person in the emergency, and automatically sends an SMS to the registered person in charge of the earth station.

The manual switch 14 is used for a test purpose after installing a new lamp security light 7 or replacing a failed lamp. At this time, the LEDs of the turn-on indicator 16 and the turn-off indicator 17 also turn on and off.

The ID SET switch is the information data required by the communication protocol. It is used when the serial number is assigned to each terminal during installation and the controller number such as Smart Security according to the serial number is matched.

The MPU unit (2) stores the sunrise / sunset data for one year in a table, and turns on / off according to the internal sunrise sunset data in case of communication failure due to communication failure. The MPU unit 2 is programmed to perform the self-mode when the wireless data signal through the NB-IoT unit 1 is not received in the management server unit 32 at an appointed time during the day, And can be generated as an external factor. Therefore, the self-mode is required. When the self-mode is used, the internal RTC unit 9 reads the time data and operates in the self-mode if it corresponds to the sunrise data.

The EEPROM 11 is characterized in that the EEPROM 11 facilitates extension of a new program and enables upgraded firmware functions to enhance scalability.

Since the communication failure may occur for a long period of time, the back-up battery unit 10 may be inserted to have its own clock. The back-up battery unit 10 updates the time once every hour and synchronizes the time. The R.T.C portion 9 updates the time by one hour in order to maintain the updated time and reduce the time error with the security of other surroundings and sends it to the MPU portion 2. [
