[0039] FIG. 1 is a diagram showing a tray and a battery movement sensing device according to an embodiment disclosed in this document.

[0040] Referring to FIG. 1, the tray 10 can accommodate the battery 20. The battery movement sensing device 100 can be connected to the tray 10. The battery movement sensing device 100 can sense the movement of the tray 10. Therefore, the battery movement sensing device 100 can sense the movement of the battery 20 accommodated in the tray 10.

[0041] The battery movement sensing device 100 according to an embodiment disclosed in this document may include a speed sensor 110, a communication unit 120, a power supply unit 130, an environmental sensor 140, and a control unit 150. The battery movement sensing device 100 may further include a storage unit 160.

[0042] The speed sensor 110 can obtain information for sensing the impact of the battery movement sensing device 100. According to an embodiment, the speed sensor 110 can obtain the speed information of the tray 10. The speed sensor 110 may include an acceleration sensor and / or an angular velocity sensor. According to an embodiment, the angular velocity sensor may include a gyro sensor.

[0043] The communication unit 120 can communicate with other electronic devices. According to an embodiment, the communication unit 120 can perform UWB (Ultra-WideBand) wireless communication. The communication unit 120 can communicate with other electronic devices at each preset communication period. The communication unit 120 can transmit the speed information obtained by the speed sensor 110 to other devices or servers other than the battery movement sensing device 100.

[0044] According to an embodiment, the communication unit 120 can operate in a wake-up mode corresponding to the communication period. After communicating with other electronic devices in the communication period, the communication unit 120 can operate in a sleep mode. When the communication unit 120 operates in the sleep mode, the battery movement sensing device 100 can reduce power consumption. According to an embodiment, the operation of the communication unit 120 may be controlled by the control unit 150. For example, the communication period of the communication unit 120 may be controlled by the control unit 150.

[0045] The power supply unit 130 can provide a driving power supply to the battery movement sensing device 100. According to an embodiment, the power supply unit 130 can provide a driving power supply to the speed sensor 110, the communication unit 120, the environment sensor 140, the control unit 150, and / or the storage unit 160. According to an embodiment, the capacity of the power supply unit 130 may be limited. The power supply unit 130 may be a power storage unit that is not constantly connected to a power supply and has a predetermined capacity.

[0046] The environment sensor 140 can measure the environmental information around the battery movement sensing device 100. The environmental information measured by the environment sensor 140 may include temperature information and / or humidity information. For example, the environment sensor 140 can measure the environmental information of the power supply unit 130. That is, the environment sensor 140 can measure the temperature and / or humidity around the power supply unit 130.

[0047] The control unit 150 can control the operation of the communication unit 120. The control unit 150 may be connected so as to be communicable with the communication unit 120.

[0048] Environmental information may be transmitted from the environment sensor 140 to the control unit 150. The control unit 150 can control the operation of the communication unit 120 in consideration of the environmental information transmitted from the environment sensor 140. The control unit 150 can calculate the available limit of the power supply unit 130 in consideration of the environmental information, and control the operation of the communication unit 120 based on the calculated available limit. According to an embodiment, the control unit 150 can adjust the communication cycle of the communication unit 120 based on the available limit.

[0049] Specifically, the control unit 150 can calculate a diagnostic coefficient regarding the power supply unit 130 based on the environmental information. The control unit 150 can calculate the available limit of the power supply unit 130 in consideration of the diagnostic coefficient. Here, the diagnostic coefficient is calculated based on the environmental information around the power supply unit 130, and may be understood as a factor related to the performance degradation of the power supply unit 130 due to the surrounding environmental information.

[0050] Specifically, the control unit 150 can calculate a diagnostic coefficient according to the temperature difference between a reference temperature preset for the power supply unit 130 and the temperature around the power supply unit 130 and / or the humidity difference between a reference humidity preset for the power supply unit 130 and the humidity around the power supply unit 130. Here, the reference temperature may be an optimal temperature that has been set so that the power supply unit 130 can exhibit optimal performance. Here, the reference humidity may be an optimal humidity that has been set so that the power supply unit 130 can exhibit optimal performance. According to an embodiment, the reference temperature may be set to 25°C which is normal temperature, and the reference humidity may be set to 0%, but it is not limited thereto. The performance of the power supply unit 130 may decrease as the temperature difference between the reference temperature and the temperature around the power supply unit 130 and / or the humidity difference between the reference humidity and the humidity around the power supply unit 130 increases. That is, the greater the temperature difference and / or the humidity difference, the more likely the power consumption of the power supply unit 130 consumed by the communication unit 120 will increase when the communication unit 120 transmits speed information to other electronic devices.

[0051] The control unit 150 can divide a high-temperature section and a low-temperature section based on the reference temperature. The control unit 150 can calculate a diagnostic coefficient by distinguishing between the case where the temperature of the power supply unit 130 belongs to the low-temperature section and the case where it belongs to the high-temperature section. According to an embodiment, the control unit 150 can calculate so that the diagnostic coefficient has a larger value when the temperature around the power supply unit 130 belongs to the low-temperature section than when the temperature around the power supply unit 130 belongs to the high-temperature section.

[0052] Generally, the performance of the power supply unit 130 may deteriorate more at lower temperatures than at higher temperatures. For example, the degree of performance degradation when the temperature of the power supply unit 130 decreases from 25°C to 0°C may be greater than the degree of performance degradation when the temperature of the power supply unit 130 increases from 25°C to 50°C. Furthermore, when the temperature of the power supply unit 130 drops below zero, the degree of performance degradation of the power supply unit 130 may become even greater. Therefore, even if the temperature difference from the reference temperature is the same when the temperature around the power supply unit 130 belongs to the low-temperature range and the high-temperature range, the control unit 150 can calculate the diagnostic coefficient when belonging to the low-temperature range to be even greater than the diagnostic coefficient when belonging to the high-temperature range.

[0053] The control unit 150 can calculate the available limit of the power supply unit 130 based on the diagnostic coefficient, the capacity of the power supply unit 130, the current consumption required for the communication unit 120 to transmit speed information to other electronic devices, and the communication time of the communication unit 120.

[0054] Here, the capacity of the power supply unit 130 may be the maximum capacity of the power supply unit 130. According to an embodiment, the capacity of the power supply unit 130 may be the maximum capacity when the power supply unit 130 is in the BOL (Beginning of Life) state. Also, the current consumption may mean the current consumption required for the communication unit 120 to transmit speed information to other electronic devices. Also, the communication time may mean the time required in the process of the communication unit 120 transmitting speed information to other electronic devices.

[0055] Here, the available limit may be a factor for determining whether the power supply unit 130 can be driven. According to an embodiment, the available limit may be expressed as the available time of the power supply unit 130. According to an embodiment, the available limit of the power supply unit 130 that can be expressed as a unit of time may be expressed as the remaining capacity of the power supply unit 130 or the number of communicable times of the power supply unit 130 through appropriate unit conversion.

[0056] For example, the available limit may be configured to decrease as the calculated diagnostic coefficient increases. That is, the greater the diagnostic coefficient, the more likely the available limit of the power supply unit 130 is to decrease.

[0057] The control unit 150 can calculate the available limit of the power supply unit 130 with reference to the following Equation 1.

[0058]

Equation

[0059] In Equation 1, D is the available limit, C is the maximum capacity of the power supply unit 130, I is the consumption current, K is the diagnostic coefficient, and T may correspond to the communication time. According to the embodiment, the unit of C is [mAh], the unit of I is [mA], K is a constant, and the unit of T may be [s] or [h]. The control unit 150 may multiply part or all of Equation 1 by an appropriate coefficient for unit conversion in order to calculate the available limit (D) in units of seconds [s] or hours [h].

[0060] The available limit (D) calculated by Equation 1 may mean the available time of the power supply unit 130 based on the current capacity of the power supply unit 130. The available time of the power supply unit 130 may decrease as the power supply unit 130 operates, that is, as it provides driving power to the communication unit 120. That is, in Equation 1, since the available limit (D) subtracts the accumulated product of the diagnostic coefficient (K) and the communication time (T), Equation 1 may mean that the available limit (D) decreases as the power supply unit 130 operates.

[0061] Also, referring to Equation 1, the available limit (D) may further decrease as the diagnostic coefficient (K) is larger. That is, the decreasing range of the available limit (D) may increase as the diagnostic coefficient (K) is calculated to be larger based on the environmental information around the power supply unit 130.

[0062] After calculating the available limit of the power supply unit 130 with reference to Equation 1, the control unit 150 can control the operation of the communication unit 120 based on the calculated available limit. The control unit 150 can determine whether the power supply unit 130 can be driven in order to control the operation of the communication unit 120. Specifically, the control unit 150 can compare the calculated available limit with a reference value and control the operation of the communication unit 120 according to the comparison result.

[0063] According to an embodiment, if the available limit of the power supply unit 130 is equal to or greater than the reference value, the control unit 150 can determine that the power supply unit 130 can be driven. At this time, the control unit 150 may maintain the communication cycle of the communication unit 120 as it is.

[0064] According to another embodiment, when the available limit of the power supply unit 130 is less than the reference value, the control unit 150 can increase the communication cycle of the communication unit 120. When the available limit of the power supply unit 130 is less than the reference value, it may correspond to the case where the driving power supply cannot be provided normally. That is, when the available limit of the power supply unit 130 is less than the reference value, the communication unit 120 may become unable to communicate with other electronic devices according to the preset communication cycle. Therefore, when the available limit of the power supply unit 130 is less than the reference value, the control unit 150 can increase the communication cycle of the communication unit 120 so that the communication frequency of the communication unit 120 decreases.

[0065] According to an embodiment, when the available limit of the power supply unit 130 is insufficient to provide sufficient power for the communication unit 120 to operate, the communication unit 120 may become unable to communicate with other electronic devices even when operating in the wake-up mode. According to an embodiment, the control unit 150 can calculate the available limit of the power supply unit 130 before the communication unit 120 operates in the wake-up mode.

[0066] The control unit 150 can control the operation of the communication unit 120. The communication unit 120 can transmit the available limit to other electronic devices. According to an embodiment, the communication unit 120 can transmit the available limit to other electronic devices only when the available limit is equal to or greater than a reference value. According to another embodiment, the communication unit 120 can transmit the available limit to other electronic devices only when the available limit is less than the reference value.

[0067] According to an embodiment of the battery movement sensing device 100 disclosed in this document, in calculating the available limit of the power supply unit 130, not only the current consumption and communication time required in the communication process and the available capacity of the power supply unit 130 that can provide driving power to the communication unit 120, but also the environmental information around the power supply unit 130 are considered, so that there is an advantage that the drivability of the power supply unit 130 can be determined more accurately.

[0068] The power supply unit 130 of the battery movement sensing device 100 according to an embodiment disclosed in this document may correspond to a power storage unit having a predetermined capacity, and performance deviation may occur depending on the ambient temperature and / or humidity during driving. Therefore, the control unit 150 calculates the available limit of the power supply unit 130 in consideration of the environmental information around the power supply unit 130 and determines the drivability, thereby preventing in advance a situation where the operation of the communication unit 120 is interrupted and / or a situation where the power supply unit 130 is over-discharged beyond the limit value.

[0069] The control unit 150 may selectively include a processor, an ASIC (application-specific integrated circuit), other chip sets, logic circuits, registers, communication modems, data processing devices, etc. known in the art in order to execute various control logics performed in the present invention. Also, when the control logic is implemented as software, the control unit 150 may be implemented as a set of program modules. At this time, the program modules may be stored in the memory and executed by the control unit 150. The memory may be inside or outside the control unit 150 and may be connected to the control unit 150 by various well-known means.

[0070] The storage unit 160 can store data, programs, or data generated during the operation and functions of each component of the battery movement sensing device 100 that are necessary for the operation and functions. The storage unit 160 is not particularly limited in type as long as it is a known information storage means capable of recording, erasing, updating, and reading data. According to an embodiment, the information storage means may include a RAM, a flash memory (registered trademark), a ROM, an EEPROM, a register, and the like. Further, the storage unit 160 can store program codes defining processes executable by the control unit 150.

The second control unit 250 can calculate the available limit of the second power supply unit 230 in consideration of the environmental information, and control the operation of the second communication unit 210 based on the calculated available limit. According to an embodiment, the second control unit 250 can adjust the second communication cycle of the second communication unit 210 based on the available limit.

[0102] Specifically, the second control unit 250 can calculate a diagnostic coefficient for the second power supply unit 230 based on the environmental information transmitted from the second environmental sensor 240. The second control unit 250 can calculate the available limit of the second power supply unit 230 in consideration of the diagnostic coefficient. Here, the diagnostic coefficient of the second power supply unit 230 is calculated based on the environmental information around the second power supply unit 230, and may correspond to a factor related to the performance degradation of the second power supply unit 230 due to the surrounding environmental information.

[0103] The method by which the second control unit 250 calculates the diagnostic coefficient of the second power supply unit 230 may be substantially the same as the method by which the control unit 150 calculates the diagnostic coefficient of the power supply unit 130 in FIG. 1.

[0104] The second control unit 250 can calculate the available limit of the second power supply unit 230 based on the diagnostic coefficient of the second power supply unit 230, the capacity of the second power supply unit 230, the current consumption required for the second communication unit 210 to transmit speed information and / or distance information to other electronic devices, and the communication time of the second communication unit 210.

[0105] The method by which the second control unit 250 calculates the available limit of the second power supply unit 230 may be substantially the same as the method by which the control unit 150 calculates the available limit of the power supply unit 130 in FIG. 1.

Here, the third reference value may be set to the same value as the first reference value in FIG. 2, but is not limited thereto.

[0108] According to an embodiment, if the available limit of the second power supply unit 230 is equal to or greater than the third reference value, the second control unit 250 can determine that the second power supply unit 230 can be driven.

[0109] According to another embodiment, when the available limit of the second power supply unit 230 is less than the third reference value, the second control unit 250 can increase the second communication cycle of the second communication unit 210. When the available limit of the second power supply unit 230 is less than the reference value, it may correspond to the case where the second power supply unit 230 cannot normally provide a driving power supply.

[0110] According to an embodiment, the second control unit 250 can calculate the available limit of the second power supply unit 230 before the second communication unit 210 operates in the wake-up mode.

Here, the fourth reference value may be set to the same value as the second reference value in FIG. 2, but is not limited thereto. The second warning message may include the available limit information of the second power supply unit 230. The second warning message may correspond to a message indicating that the battery position sensing device 200 is in the non-operation danger range. Here, the non-operation danger range may mean a range in which the battery position sensing device 200 may stop operating.
