Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Also, like reference numerals in the drawings denote like elements.

Referring to FIG. 1, a system for managing a battery operation sensor according to an embodiment of the present invention is a station that is spatially spaced apart from at least one battery operation sensor 110 and at least one battery operation sensor 110 and connected in wireless communication. 120. In this case, the at least one battery operation sensor 110 may be connected to the station 120 by wire, such as an optical cable, in addition to wireless communication.

Hereinafter, the at least one battery operation sensor 110 will be described as an illuminance sensor mounted on the street light 111, but is not limited to the illuminance sensor, but may be a vibration sensor, a temperature sensor, an acceleration sensor, or the like.

The at least one battery operation sensor 110 is a sensor supplied with power from the battery. When all of the battery power is exhausted, the operation may be stopped. Accordingly, there is a need for a technique for efficiently managing a battery in at least one battery operation sensor 110. Accordingly, the at least one battery operation sensor 110 according to an embodiment of the present invention checks the remaining capacity of the battery, and if the remaining amount of the identified battery is smaller than a preset reference remaining amount, the at least one battery operation sensor 110. By transmitting a call for the remaining capacity of the battery or the state of the at least one battery operation sensor 110 to the station 120 to manage the station 120 to determine the charging method of the battery, it is possible to efficiently manage the battery have.

In this case, the at least one battery operation sensor 110 may periodically check the remaining amount of the battery based on a preset time period and transmit a call to the station 120. In addition, the at least one battery operation sensor 110 sets a plurality of preset residual levels to supply power to the at least one battery operation sensor 110 to check the remaining amount of the battery gradually being consumed, By comparing the remaining amount and the plurality of set reference remaining amounts, it is possible to check the remaining amount of the battery step by step.

For example, if 75%, 50%, and 25% of the total power of the battery is set as reference residuals and the time period is set to 8 hours, the at least one battery operation sensor 110 may perform the By checking the remaining amount, when the remaining amount of the identified battery is less than 75%, 50% and 25%, a call to the station 120 for the remaining amount of the battery or the state of the at least one battery operation sensor 110 may be transmitted, respectively. have. More specifically, for example, the at least one battery operation sensor 110 checks the remaining capacity of the battery every 8 hours, and at the first confirmation time when it is determined that the remaining battery level is less than 75%, the station 120 Can send a call indicating that the battery is below 75%. Thereafter, the at least one battery operation sensor 110 continuously checks the remaining capacity of the battery at 8-hour intervals, and at the first confirmation time when it is determined that the remaining battery level is less than 50%, the station 120 returns to the station 120. A call can be sent to indicate that the battery is below 50%.

In addition, after the at least one battery operation sensor 110 transmits the call to the station 120, in order to prevent the battery from being consumed, the at least one battery operation sensor 110 may be switched to either a shutdown state or a sleep state. Such a state transition may be automatically performed without separate instructions from the station 120.

In principle, the at least one battery operation sensor 110 is directly connected to the station 120 through wireless communication. However, when the direct connection with the station 120 is difficult, the at least one battery operation sensor 110 is different from at least one battery operation sensor 110. It may be directly connected to the station 120 through one battery operation sensor. Here, the meaning that the battery operation sensor 110 is directly connected to the station 120 means that the battery operation sensor 110 is wirelessly or wiredly connected to the station 120 through a single hop communication link rather than a multi-hop communication link. Means that.

The description thereof will be described in detail with reference to FIG. 2.

The station 120 activates the at least one battery operation sensor 110 based on a call for the remaining battery level or the state of the at least one battery operation sensor 110 received from the at least one battery operation sensor 110. The time may be predicted and a charging method of the at least one battery operation sensor 110 may be determined. For example, the station 120 may dispatch a robot agent to charge the battery to the station 120 or may charge the battery using a wireless power charging function. In addition, the station 120 may send a command to automatically replace the battery or may send a command to operate with energy harvesting by sunlight.

Here, in determining the charging method, the station 120 receives at least one of IP (Internet Protocol) information or Global Positioning System (GPS) information corresponding to at least one battery operation sensor 110 stored in advance. Time information is available. For example, as a result of analyzing GPS information corresponding to at least one battery motion sensor 110 that has transmitted a call, at least one battery motion sensor 110 is located in an area where the robot agent is difficult to access, and at least one If a call is received from the battery operation sensor 110 of 5 minutes ago that the remaining battery capacity is 1%, the station 120 determines that there is no time for dispatching the robot agent, and uses the wireless power charging function to at least one battery. The battery of the motion sensor 110 may be charged.

If the station 120 does not store IP information and GPS information corresponding to the at least one battery operation sensor 110 in advance, in the process of receiving a call from the at least one battery operation sensor 110, at least one At least one of IP information or GPS information corresponding to the battery operation sensor 110 may be additionally received and stored.

If a call is received that is less than the remaining 10%, the station may store time information 340 at which the call was received and calculate the remaining amount prediction information 360 based on the time information 340. Thereafter, the station determines a charging method for the at least one battery operation sensor based on the calculated remaining prediction information 360, the GPS information 320, and the IP information 330. Management can be performed.

Here, the at least one battery operation sensor may be directly connected to the station or through another at least one battery operation sensor distinguished from the at least one battery operation sensor. In addition, when the at least one battery operation sensor does not store IP information and GPS information corresponding to the at least one battery operation sensor in advance, the at least one battery operation sensor transmits at least one of the IP information and the GPS information to the station during the call transmission. Can transmit

After the call is transmitted, the at least one battery operated sensor may transition to either a shut down state or a sleep state (440).
