The external communication device 10 may be a device capable of short-range network communication such as Bluetooth, NFC (Near Field Communication), Zigbee, WiFi, and long distance network communication such as 3G, 4G, 5G communication, It is used in a broad sense. The smart lantern apparatus 100 can transmit information related to occurrence of a fire and whether or not a battery is discharged to an external communication device 10. [ The external communication device 10 can transmit the occurrence of a fire through communication with the control server.

The control server 20 is a server managed by an emergency disaster center such as a fire station or a police station communicating with an external communication device or a smart lantern apparatus. The control server 20 can receive information on a fire from an external communication device or a smart lantern device and input a firefighting manpower to the site. In this case, the control server 20 can receive location information of a fire scene from an external communication device or a smart lantern device. Also, the control server 20 can communicate with an external communication device or a smart lantern device to receive additional information such as the image of a fire scene, the number of people detected, and the like.

The smart lantern apparatus 100 is used in an outdoor accommodation such as a tent, and can detect a fire in an outdoor accommodation. The smart lantern device communicates with an external communication device or a control server, and can notify a fire when it is detected at an outdoor accommodation facility. The smart lantern apparatus 100 may have a plurality of LEDs and may be used by a user as a portable lantern. In addition, the smart lantern apparatus 100 manages internal battery power and transmits it to an external communication device or a control server so that the smart lantern apparatus 100 can monitor and maintain the battery in a discharged state or externally.

Hereinafter, the smart lantern apparatus 100 will be described in detail with reference to FIG.

3 is a detailed configuration diagram of the smart lantern apparatus according to FIG.

3, the smart lantern apparatus 100 includes a communication unit 110, an illumination unit 120, a fire detection unit 130, a power management unit 140, and a control unit 150 .

The communication unit 110 communicates information such as internal fire occurrence with an external communication device or a control server. The communication unit 110 can also receive a control command from an external communication device. The communication unit 110 may be capable of short range network communication such as Bluetooth, NFC (Near Field Communication), Zigbee, WiFi, and long distance network communication such as 3G, 4G, 5G communication or satellite communication. The communication unit 110 may provide location information of a fire site to communicate with an external communication device as well as a control server.

The illumination unit 120 arranges a plurality of LEDs to output illumination. It can be configured using white LED or RGB LED.

The power management unit 140 charges or discharges at least one battery built in the smart lantern apparatus 100. A plurality of batteries can be accommodated in the smart lantern apparatus 100 and charged. In this case, the power management unit 140 can acquire characteristic information such as a charging power, a charging voltage, and a charging current of each battery. The power management unit 140 transmits the state of charge of each battery to an external communication device or outputs it to the control unit 150. [

Also, when the plurality of different batteries are simultaneously charged, the power management unit 140 may divide the charging timing of each battery to distribute the power within the maximum power. For example, a first control signal, which is a charging signal of the first battery, is generated and a second control signal, which is a charging signal of the second battery, is generated, And controls the sum of the charging powers to be less than or equal to the maximum power. This is for not dividing the first battery and the second battery at all times, but dividing the charging power within the maximum power range by selectively charging the divided time. The first battery and the second battery can be prevented from exceeding the total maximum power by changing the charging timing.

In addition, when the second battery is operated during operation of the first battery, the power management unit 140 allows the first battery and the second battery to operate simultaneously when the charging power of the first battery and the second battery is less than the maximum power, The controller controls the charging power of the first battery and the second battery to be kept below the maximum power by charging the second battery while reducing the charging interval of the first battery.

Also, the power management unit 140 may discharge power to at least one battery accommodated in the smart lantern apparatus 100. The power management unit 140 receives electricity from an external power source to charge the battery, but discharges the battery when the power source is disconnected from an external power source. The power management unit 140 can also discharge power when communicating with an external communication device even when the battery is being charged or fully charged, or when supplying power to the illumination unit 120.

In addition, the power management unit 140 may control the sum of the first reaction signals obtained by applying a plurality of first test signals to the battery at predetermined time intervals, and the second test signals superimposed on the plurality of first test signals And the second reaction signal obtained by comparing the first and second reaction signals. This is to enable the user to determine whether the internal battery of the smart lantern apparatus 100 can be used when the performance of the internal battery is deteriorated due to frequent charge and discharge. The performance of the battery in the power management unit 140 will be described in detail with reference to FIG.

The control unit 150 transmits the charging state of the battery and the environmental state of the sensing area to the external communication device or the control server at a predetermined time period. Here, the environmental information is used to include information such as the occurrence of fire, temperature, and humidity. When the battery is discharged or a fire occurs in the sensing area, the control unit 150 may transmit an alarm signal to an external communication device or a control server and output the alarm signal through a speaker. Before the battery is discharged, an alarm may be sent to the communication device used by the user to warn the user of the discharge risk of the battery. Accordingly, when a fire occurs, an alarm signal is transmitted to an external control server as well as a communication device used by the user, thereby minimizing the damage of the person.

Also, the control unit 150 may output a pre-set warning sound through the speaker to alert the sleeping user in the outdoor accommodation. A plurality of speakers arranged in a line may be formed inside the smart lantern apparatus. This is to adjust the output of the speaker so that the warning sound is transmitted to the user who is lying in the outside accommodation as much as possible.

Meanwhile, the smart lantern apparatus 100 according to the embodiment of the present invention may further include an insect-proof part 160 and a fire extinguisher part 170. [

The insect control part 160 outputs an ultrasonic wave of a predetermined frequency through a speaker or outputs light of a predetermined wavelength through the illumination part to attract or exterminate insects. The insect control part 160 can output the frequency of the preset area to inhibit the activity of insects such as mosquitoes. Also, the insect control unit 160 can output illumination of a wavelength that attracts insects using the illumination unit, and remove insects attracted to the high temperature heat transfer plate (not shown) with high heat. The insect control part 160 can set the operation time differently according to the activity time of the pest.

The fire extinguishing unit 170 is formed of a fire extinguishing material and emits fire extinguishing material when detecting a gas or flame exceeding a predetermined concentration in the outdoor accommodation from the fire sensing unit. It is also possible that the extinguishing unit 170 discharges the extinguishing material through the nozzle at a preset pressure. In this case, it is preferable that the fire extinguishing unit 170 is designed such that the nozzle is rotatable so as to discharge the extinguishing material only in the sensing area where the fire is sensed.

4 is an exemplary diagram for explaining that the smart lantern apparatus according to FIG. 1 sends a fire alarm to an external communication device.

Referring to FIG. 4, the external communication device 10 may include time information of occurrence of a fire and location information of occurrence of a fire. The external communication device 10 can transmit the fire alarm to the control server. When the external communication device 10 is provided with the location information of the fire by the GPS information, it is also possible to check the location information with the map by linking the map program installed in the communication device 10. It is also possible to receive image information on fire from the smart lantern apparatus. Accordingly, the user who manages the external accommodation can receive the fire situation promptly regardless of the place.

FIG. 5 is a diagram illustrating current-voltage characteristics of a battery of the smart lantern apparatus shown in FIG. 1, which is determined by the power management unit.

Referring to FIG. 5, in the case of (a), the voltage-current characteristic curve of the battery can be expressed as V = -2.498 * I + 41.26 [V]. In this case, assuming that the current, which is the characteristic input signal of the battery itself, is set to 1 [A], the voltage of the characteristic reaction signal is 38.7620 [V]. For example, when the first test signals are 0.1 [A] and 0.2 [A], respectively, 1.1 [A] and 1.2 [A] are added to the characteristic input signal 1 [A] The reaction signals are 38.5122 [V] and 38.2624 [V], respectively.

In addition, the overlapped second test signal becomes 0.3 [A] which is the sum of 0.1 [A] and 0.2 [A], 1.3 [A] combined with the characteristic input signal 1 [A] Is 38.0126 [V]. The sum of the first reaction signals when the first inspection signal is 0.1 [A], 0.2 [A] is 38.5122 [V] + 38.2624 [V] = 76.7746 [V] A], the second reaction signal is 38.0126 [V], and the characteristic reaction signal of the battery is 38.7620 [V], so 38.0126 [V] + 38.7620 [V] = 76.7746 [V]. As a result, since the sum of the second reaction signals corresponding to the plurality of first inspection signals and the second reaction signal corresponding to the second inspection signal have the same value, the state of the battery is established by the principle of superposition, It can be judged as a normal state.

On the other hand, in case of (b), the voltage-current characteristic curve can be expressed as V = -0.067 * I3 + 0.6943I2-3.992I + 41.33 [V]. In this case, assuming that the characteristic input signal of the battery itself is set to 1 [A], the characteristic response signal voltage is 37.9653 [V]. For example, when the first test signals are 0.1 [A] and 0.2 [A], respectively, 1.1 [A] and 1.2 [A] are added to the characteristic input signal 1 [A] The reaction signals are 37.6897 [V] and 37.4236 [V], respectively.

Also, the overlapped second test signal is 0.3 [A], which is the sum of 0.1 [A] and 0.2 [A], and 1.3 [A] combined with the battery characteristic input signal 1 [A] The response signal is 37.1666 [V]. The sum of the first reaction signals when the first inspection signal is 0.1 [A] and 0.2 [A] is 37.6897 [V] + 37.4236 [V] = 75.1133 [V] The second reaction signal is 37.1666 [V] + 37.9653 [V] = 75.1319 [V] because the reaction signal is 37.1666 [V] and the response signal according to the characteristic input signal of the battery is 37.9653 [V]. As a result, since the first reaction signal, which is the sum of the respective reaction signals corresponding to the plurality of first inspection signals, and the second reaction signal corresponding to the second inspection signal, which is a signal superimposed on the first reaction signal, have different values, Is not established and has non-linearity, it can be judged as an abnormal state.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, Therefore, the present invention should be construed as a description of the claims which are intended to cover obvious variations that can be derived from the described embodiments.
