3, the data merge unit 140 includes a second power source unit 170, a second communication unit 172, a second control unit 174, a third communication unit 176, (178), and a second conversion unit (180).

The second power supply unit 170 is connected to the second communication unit 172, the second control unit 174, the third communication unit 176, the second measurement unit 178, the second conversion unit 176, And supplies the power supply voltage to the unit 180.

The second communication unit 172 receives the digital type cell voltage, the cell internal resistance, the bank current, and the cell voltage from the first communication unit 168 of the first and second measuring devices 130 and 132 under the control of the second control unit 174, Cell internal resistance, the bank current, and the second temperature signal to the second controller 174, and transmits the second temperature signal to the second controller 174 in a free near range such as Bluetooth, Zigbee, Wireless communication module.

For example, the second conversion unit 180 may be an analog-to-digital converter (ADC).

The second control unit 174 includes a second power supply unit 170, a second communication unit 172, a second control unit 174, a third communication unit 176, a second measurement unit 178, a second conversion unit 180 The cell voltage, the cell internal resistance, the bank current, and the room temperature of the first to fourth batteries 122, 124, 126, and 128 are periodically measured.

Also, the second control unit 174 transmits the first temperature signal and the theft signal of the digital type corresponding to the room temperature and the theft condition to the third communication unit 176.

The second controller 174 may control the real time cell voltage, the real time cell internal resistance, and the real time cell voltage using the second temperature sensor 138, the first and second meters 130 and 132, The real-time bank current and the real-time cell temperature may be periodically measured (e.g., 5 minutes) and the first temperature sensor 136 may be used to periodically (e.g., 5 minutes) measure the real-time room temperature.

For example, the cycle of measurement of the cell voltage, the cell internal resistance, the bank current, the room temperature, and the cell temperature when the room temperature deviates from a certain standard is determined by the first to fourth batteries 122, 124, 126, May be shorter than the period of measurement of the cell voltage, the cell internal resistance, and the bank current when used.

The third communication unit 176 transfers the average cell voltage, the average cell internal resistance, the average bank current, and the average room temperature to the server 152 of the management center 150 under the control of the second control unit 174, And transmits the measured first real-time cell voltage, real-time cell internal resistance, and real-time bank current to the server 152 of the management center 150. The first temperature signal and the theft signal of the digital type corresponding to the room temperature, The real-time internal resistance, the real-time bank current, the real-time room temperature, and the real-time cell temperature to the server 152 of the management center 150, Bluetooth, Zigbee, and the like.

Meanwhile, the server 152 of the management center 150 communicates with the data combiner 140 of the base station tower 120 by wire or wireless, so that the first to fourth batteries 122, 124, 126 and 128 are not used In the abnormal state in which the first to fourth batteries 122, 124, 126, and 128 are used, the real-time cell voltage, the real-time cell voltage, the real- A real-time cell voltage, a real-time internal voltage, and a real-time internal voltage when the room temperature deviates from a specific reference, and receives a first temperature signal and a theft signal of a digital type corresponding to room temperature and theft, Real-time bank current, real-time room temperature, and real-time cell temperature.

The indicator 154 communicates with the server 152 in wired and wireless communication to determine the average cell voltage of the first to fourth batteries 122, 124, 126 and 128, the average cell internal resistance, the average bank current, Battery state information such as cell voltage, real-time internal resistance, real-time bank current, and real-time cell temperature, and base station tower status information such as room temperature and theft status. Indicator 154 may be a touch monitor.

The first and second terminals 156 and 158 communicate with the server 152 via wired or wireless communication so that the average cell voltage of the first to fourth batteries 122, 124, 126 and 128, the average cell internal resistance, Battery state information such as a current, an average room temperature, a real time cell voltage, a real time internal resistance, a real time bank current, and a real time cell temperature, and a room temperature and a stolen state, 156, and 158 may be a computer or a mobile terminal, respectively.

The server 152 compares the average cell voltage, the average cell internal resistance, the average bank current, and the average room temperature of the first to fourth batteries 122, 124, 126, and 128 with the real-time cell voltage, Real-time bank current and real-time cell temperature.

The server 152 compares the state of the first to fourth batteries 122, 124, 126, and 128 with the reference value by comparing the deviation of the real-time cell voltage or the real-time cell voltage, the real-time bank current, .

For example, if the cell voltages of the first to fourth batteries 122, 124, 126, and 128 are within the reference voltage range, the first to fourth batteries 122, 124, 126, And determines that the first to fourth batteries 122, 124, 126, and 128 are in an abnormal state when the cell voltages of the first to fourth batteries 122, 124, 126, and 128 are out of the reference voltage range .

If the deviation of the cell voltages of the first to fourth batteries 122, 124, 126, and 128 is less than the reference deviation, the first to fourth batteries 122, 124, 126, The first to fourth batteries 122, 124, 126, and 128 may be determined to be in an abnormal state if the deviation of the cell voltages of the first to fourth batteries 122, 124, 126, and 128 is equal to or greater than the reference deviation.

As the charging and discharging of the first to fourth batteries 122, 124, 126 and 128 increases, the variation of the cell voltage between the first to fourth batteries 122, 124, 126 and 128 becomes larger. The battery having the higher cell voltage of the first to nth batteries 122, 124, 126, and 128 connected thereto quickly reaches the charging end voltage, so that the remaining battery does not reach the charging end voltage. The sulphation of the cell is further exacerbated, leading to a shortening of the life span.

Accordingly, if the deviation of the cell voltage is equal to or greater than the reference deviation, the first to fourth batteries 122, 124, 126, and 128 may be determined to be in an abnormal state.

Meanwhile, the server 152 compares the deviation of the real-time cell internal resistance or the real-time internal resistance with the reference value to more accurately grasp the states of the first to fourth batteries 122, 124, 126, and 128.

For example, as the first to fourth batteries 122, 124, 126 and 128 are continuously used, a variation occurs in the cell internal resistance of the first to fourth batteries 122, 124, 126, and 128 Accordingly, a variation in the cell voltages of the first to fourth batteries 122, 124, 126, and 128 may occur.

Therefore, the state of the first to fourth batteries 122, 124, 126, and 128 can be determined by comparing the internal resistance of the real-time cell with the resistance of the initial cell. For example, 20%, the capacity drops to 80% when the real-time cell internal resistance increases by 30% to 50% of the initial cell internal resistance, and the real-time cell internal resistance decreases to 100 %, The battery can not be restored and replacement may be necessary.

Here, when the server 152 determines that each of the first to fourth batteries 122, 124, 126, and 128 is in an abnormal state using the deviation of the cell voltage, the cell voltage deviation, the cell internal resistance, , The alarming means such as an alarm or an emergency light can be used to inform the user of the abnormal state and the user can charge the battery for a long time with a constant voltage slightly higher than the voltage of the low current charging or floating charge which is long- The first to fourth batteries 122, 124, 126, and 128 may have a uniform state by performing an equalizing charge.

If the directions of the bank currents of the first to fourth batteries 122, 124, 126, and 128 are the same as the reference direction, it is determined that the base station tower 120 is in the active state, and the first to fourth batteries 122, 124, 126, and 128 are different from the reference direction, it can be determined that the base station tower 120 is in a power failure state.

The fact that the bank current flows in the same direction as the current flowing during discharging means that the base station tower 120 is in operation and therefore the direction of the bank current of the first to fourth batteries 122, It can be determined that the base station tower 120 is in the active state and the fact that the bank current flows in the same direction as the current flowing in discharging means that the base station tower 120 is in the power-off state, If the directions of the bank currents of the first to fourth batteries 122, 124, 126, and 128 are different from the reference direction, it can be determined that the base station tower 120 is in the power failure state.

In order to sense the direction of the bank current, the battery monitoring system 110 for the base station tower may include a current sensor (not shown), which may be embedded in the first and second meters 130 and 132 .

2, the first measuring unit 162, the first converting unit 164 and the first communicating unit 168 are constructed separately from the first controlling unit 166. However, in another embodiment, the measuring unit 162 ), The first conversion unit 164, and the first communication unit 168 may be incorporated in the first control unit 166.

Although the second communication unit 172, the third communication unit 176, the second measurement unit 178 and the second conversion unit 180 are configured separately from the second control unit 174 in FIG. 3, In another embodiment, the second communication unit 172, the third communication unit 176, the second measurement unit 178, and the second conversion unit 180 may be incorporated in the second control unit 174.

As shown in FIGS. 4A and 4B, when the first to twenty-fourth batteries having a nominal voltage of 2 V are charged, the end-of-charge voltage of each battery is 2.5 V, the end- A charger set to 60 V can be used. When the cell voltages of the first to 24th batteries reach the charging end voltage, the charger can be immediately stopped or charged and stopped for 1 to 2 hours.

Due to the chemical characteristics of the first to twenty-fourth batteries, a cell voltage deviation occurs between the first to twenty-fourth batteries during charging and discharging.

Since the first to twenty-fourth batteries are connected in series, the charging end voltage of a relatively high cell voltage of the battery during charging is quickly reached, and the remaining battery is in a state of insufficient charging that can not be charged by the charging end voltage , The states of the first to 24th batteries can be monitored by the deviation of the cell voltage or the cell voltage.

For example, when a charger having a reference voltage range of 2.60 V to 2.70 V and a reference deviation of 0.10 V is used, as shown in FIG. 4A, the cell voltages of the first to the twenty-fourth batteries are 2.62 V To 2.68 V and has a value within the reference voltage range, and when the deviation of the cell voltages of the first to the twenty-fourth batteries is measured to be 0.06 V and has a value less than the reference deviation, State.

4B, the cell voltages of the first to the twenty-fourth batteries are measured to be 2.49 V to 2.73 V and have values outside the reference voltage range, and the deviation of the cell voltages of the first to the twenty-fourth batteries The first to the twenty-fourth batteries may be determined to be in an abnormal state, and the user may select the low-current charging mode or the even-numbered charging mode according to the state information of the first to twenty- The first to the 24th batteries can be made uniform by charging.

A configuration of a first measurement unit for measuring a cell internal resistance of a battery monitoring system for a base station tower according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 5 is a diagram illustrating a first measurement unit of a battery monitoring system for a base station tower according to an embodiment of the present invention, and will be described with reference to FIGS. 1 to 3. FIG.

5, the first measuring unit 162 connected to the first to fourth batteries 122, 124, 126 and 128 includes a current amplifying unit 182, a sine derivative 184, An amplifying unit 186, a noise removing unit 188, and an averaging unit 190.

The sine derivative 184 generates a sine wave for measuring the internal resistance of the cell and transmits it to the current amplifier 182. The current amplifier 182 amplifies the sine wave current and corrects the voltage To the first to fourth batteries 122, 124, 126, and 128, respectively.

The voltage amplifying unit 186 amplifies the output voltages of the first to fourth batteries 122, 124, 126 and 128 by applying a sine wave and transmits the amplified output voltage to the noise removing unit 188.

The noise removing unit 188 removes noise from the output voltage and transmits the noise to the average measuring unit 190.

The average measuring unit 190 calculates an internal resistance of the cell by measuring an average of noise-removed output voltages, and transmits the calculated internal resistance of the cell to the first converting unit 164.

A monitoring method using the battery monitoring system for a base station tower according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 6 is a flowchart illustrating a method of monitoring a battery monitoring system for a base station tower according to an embodiment of the present invention, and will be described with reference to FIGS. 1 to 3. FIG.

6, the base station tower battery monitoring system 110 monitors the first to fourth batteries 122, 124, 126, 128 of the first and second banks BK1, BK2 in real time (St10).

Thereafter, the battery monitoring system 110 for the base station tower periodically detects the cell voltages of the first to fourth batteries 122, 124, 126, and 128 using the first and second meters 130 and 132, The resistance and bank currents are periodically measured (st12) and the first temperature sensor 136 is used to periodically measure the room temperature of the base station tower 120.

Then, the base station tower battery monitoring system 110 determines whether or not the first to fourth batteries 122, 124, 126, and 128 are used (st14).

For example, in a normal state, the base station tower 120 uses a main power supplied via a power line or the like instead of the first to fourth batteries 122, 124, 126 and 128, and in an abnormal state such as a power failure, Uses the power of the first to fourth batteries 122, 124, 126, and 128.

Thereafter, the battery monitoring system 110 for the base station tower calculates the average cell voltage, the average cell internal resistance, the average bank current, and the average cell voltage for one day when the first to fourth batteries 122, 124, 126, (St16), and stores the calculated average cell voltage, the average cell internal resistance, the average bank current, and the average room temperature (st18).

For example, the average cell voltage, the average cell internal resistance, the average bank current, and the average room temperature may be stored in the storage of the server 152.

On the other hand, the base station tower battery monitoring system 110 immediately measures the real-time cell voltage, the real-time cell internal resistance and the real-time bank current when the first to fourth batteries 122, 124, 126 and 128 are used st20), the measured real-time cell voltage, the real-time cell internal resistance, and the real-time bank current (st22).

For example, the real-time cell voltage, the real-time cell internal resistance, and the real-time bank current may be stored in the storage unit of the server 152.

Then, it is determined whether the room temperature of the base station tower 120 exceeds a specific reference temperature range (st24).
