3 is a diagram illustrating a method for controlling a situation awareness event air conditioning notification system using a mobile device according to an embodiment of the present invention.

Referring to FIG. 3, a method for controlling a situation awareness event air conditioning notification system using a mobile device is described. When a mobile device is registered with the control center server (S101), the location signpost value of the mobile device is transmitted in real time to the control center server (S102). It starts.

Mobile device registration contrasts with relevant information stored on the control center server, such as name, gender, date of birth, ID, password, hobbies, favorite teachers, etc., and related information entered through the mobile device. Or, it is performed by entering mobile device identification information, model name, etc. into the control center server.

The characteristics of each photographing area in which the camera is installed and the event occurrence criteria are set as required (S103). For example, in the case of military areas where entry of uninspected objects such as people, automobiles, and drones is restricted, movement monitoring is performed, and in cases where there are many people entering and exiting such as cultural properties, fire occurrence monitoring is performed. The image analysis algorithm is selectively applied according to the characteristics and needs of the installation area.

According to the criteria set in step S103, the image of the photographed area is analyzed (S104), and if it is determined that an event has occurred, an event generation signal is generated (S105), and a push event generation signal is transmitted to a mobile device concerned within a set radius (S106). ).

From the set time before the event occurrence time to the present, for example, from 5 minutes to the present time, from 1 hour to the present, the video information is extracted and transmitted to the mobile device concerned (S107).

A push notification is displayed on the screen by receiving a push event generation signal from the person's mobile device (S108).

When the relevant person confirms the push notification, dispatches to the site, or checks the video to notify the relevant agency of the site judgment result, dispatch completion, etc. (S109), the mobile device of the relevant person existing within the set radius excluding the person who reported the result To form a stop-stop pop-up (S110).

Referring to FIG. 4, in another embodiment of the present invention, after steps S109 and S110, an additional manpower request and a situation termination button are formed in the mobile device of the person concerned with the result (S111).

When it is determined whether the user selects the additional manpower request button (S112), and the user selects the additional manpower request button, the control center server transmits an additional manpower request signal to the mobile device of the related person within the set radius to form an additional manpower request popup. (S113). If the additional human resource request pop-up is viewed and the additional human resource request is not accepted, the process returns to step S113 to form a pop-up to another person who has entered the setting range, and if accepted, the mobile device of the person who accepted the request is compared with the location coordinates of the site (S115). ).

It is determined whether the mobile device of the relevant person has entered within a certain range of the site location coordinates (S116), and if it has not entered within a certain range, the process returns to step S115. Leave the arrival record (S117).

In step S116, it is determined whether the coordinates are the same or not, since there is a GPS error to determine whether the coordinates are the same, and may exist in the field even if the coordinates are not actually the same. It is judged that it has reached.

If the person notifying the result does not select the request for additional manpower, or if it is determined that the additional manpower has been reached by requesting additional manpower, it is determined whether or not the situation is selected (S118), and when the situation is terminated, it is terminated. If it is not selected, it returns to step S112 to determine whether a button for requesting additional personnel is selected.

In another example, the mobile device of the air conditioning system is a wearable device, or in another example, the wearable device interlocked with the mobile device further includes. The wearable device measures the pulse, body temperature, etc. of the person involved, including the biometric module, and checks the safety of the person involved in the field. The biometric module includes a blood pressure monitor, a pulse meter, and a diabetes monitor.

If the pulse, body temperature, etc. rise above a certain value or fall below a certain value, and it is determined that the problem has occurred to the related person, the control center server transmits the abnormality signal to the control center server and the position coordinates of the related person suspected to have occurred, and the control center server Rescue sends a rescue dispatch signal to another person in the vicinity using the location coordinate value of the mobile device.

In another example, when a related person abnormal signal occurs, a pop-up window pops up asking for an emergency with a warning sound on the related person's mobile device where the abnormal signal occurred, and 'No', which means that the related person is not abnormal within a certain time, for example, within 30 seconds. If the button of is not selected, a rescue request signal is transmitted to a mobile device of a nearby person concerned.

Alternatively, a quick rescue can be made by transmitting the dispatch signal, the pulse of the related person, body temperature, and the time when the abnormality occurred to the medical institution, etc.

The control center server further includes an emergency power supply for receiving constant power through an A / D converter and continuing operation when a power failure occurs.

Although described above with reference to the drawings according to embodiments of the present invention, those of ordinary skill in the art to which the present invention pertains may be able to perform various applications, modifications, and adaptations within the scope of the present invention based on the above contents will be. Accordingly, the true scope of protection of the present invention should be defined only by the appended claims.

The emergency power supply supplies power to the fire alarm 300 including a DC-DC converter.

The DC / DC converter circuit of the synchronous rectifying switching regulator has a phenomenon in which the PWM frequency is distorted due to external factors such as overheating, and there is a phenomenon in which the circuit malfunctions because there is no input / output overvoltage protector or overheat detection circuit.

Accordingly, the present invention applies the DC-DC converter shown in FIG. 5. In more detail, when the input voltage is input, it passes through the filter 401, and the overvoltage is removed by the input overvoltage protector 404 (Input OVP). The voltage is stepped up or stepped down through 402.

The signal switched by the PWM frequency is switched by the FET device, which also senses the current of the transformer 402 to input the PWM control signal. The signal boosted by the transformer 402 is filtered by the LC filter 403, which is a low-frequency filter, to be an output voltage. An overvoltage protector 405 is provided at the output voltage stage to suppress the occurrence of an overvoltage when it occurs.

The PWM controller 406 is a PWM input frequency generator circuit for dividing the input voltage, and the PWM controller 406 is connected to the overheat protection circuit 408.

The function of the overheat protection circuit 408 detects overheat in the DC / DC converter circuit of the synchronous rectifying switching regulator, and transmits an overheat detection signal to the control unit. In addition, the transformer 402 amplifies or drops the input voltage, and the voltage is determined in proportion to the ratio of the number of windings of the primary and secondary sides of the transformer 402. In addition, a current sensor 407 is placed to measure the current of the transformer 2, and the current sensor 407 is typically a current sensor using a Hall effect, a current sensor using a current loop, or the like.

When the current value of the current detector 407 is equal to or greater than a certain voltage, the control circuit detects this and sends an overcurrent message, and if necessary, cuts the current. A switching device that converts AC voltage into a DC / DC converter circuit of a synchronous rectifying switching regulator uses a FET, and applies a voltage to the gate terminal of the FET to turn the FET ON / OFF.

The LC filter 403 connected to the output voltage terminal is a low-pass filter, and is used to smooth the voltage. The PWM controller has a structure that can be remotely monitored by transmitting communication signals.

In addition, the PWM controller 406 circuit is as shown in FIG. 6, and the overheat protection circuit 407 is as shown in FIG. Figure 8 is a PWM controller circuit, the PWM output frequency is determined by R3, C2, C34 of Figure 9. When the temperature of the output frequency of the PWM rises due to overheating of the DC / DC converter, fluctuation of the frequency occurs. In order to prevent this, the capacitance value is changed to a MLCC capacitor whose capacitance value is stable even when the temperature rises in the conventional tantalum capacitor. Stability is increased to prevent frequency distortion due to temperature.
