Method for detecting surge occurrence and its base station

The present disclosure relates to detecting the occurrence of a surge in a base station of a mobile communication system.

In a mobile communication system, a base station may include a data processing unit (DU), a radio unit (RU), and an antenna. The antenna of the base station is installed outside, such as on the roof of the building, and the data processing unit (DU) and the radio unit (RU) of the base station may be installed inside the building. However, recently, for telecommunication service providers, for cost reduction and maintenance convenience, the RU and antenna of the base station are installed in places directly exposed to lightning, such as iron towers or rooftops, and the DU of the base station can be installed separately inside the building. have.

On the other hand, in order to protect from lightning, a surge protection circuit (or surge protection device) may be included in the RU device. There are several types of protection devices used in the surge protection circuit, and a gas discharge tube (GDT) is widely used among the various types of protection devices. The gas discharge tube is positioned between the signal line to which the surge is applied and the ground line, and when the surge is applied, the gas discharge tube may operate to transmit the surge to the ground line using arc-discharge of gas existing inside the component. The lifespan of these GDT parts can be determined by the amount of surge applied and the number of surges. For example, if the surge amount and the number of surge occurrences exceed the threshold values, the GDT component may not be able to block the surge from flowing into the RU device.

Therefore, the base station manager needs to replace the surge protection circuit by estimating the lifespan of the surge protection circuit coupled to the RU device in order to safely protect the RU device from surge occurrence.

An embodiment may provide a method and apparatus for detecting a surge in a base station device.

Another embodiment may provide a method and apparatus for predicting the lifespan of a surge protection circuit in a base station device.

Another embodiment may provide a method and apparatus for resetting the base station device when the surge voltage or surge current value introduced from the base station device exceeds an expected range.

Another embodiment may provide a method and apparatus for detecting a surge using an optical sensor that is not electrically connected to a surge protection circuit in a base station device.

The device for detecting the occurrence of a surge according to an embodiment includes a detection unit that detects a signal corresponding to a change in state of the surge protection device through a sensor and a surge introduced into the surge protection device based on the signal detected by the sensor and a bibliographic determination unit that determines whether or not it occurs.

A base station device according to an embodiment includes a surge protection device, a surge detection device for detecting a state change of the surge protection device through a sensor, and a processor for processing an interrupt related to surge generation based on a signal detected from the surge detection device includes

A method of operating a base station apparatus according to an embodiment includes detecting a state change of a surge protection device through a sensor, and processing an interrupt related to surge generation based on the detected signal.

As described above, by predicting the replacement timing of the surge protection circuit in the base station device and providing the result to the manager, it is possible to stably protect the base station device from the incoming surge.

In addition, when the surge voltage or surge current flowing into the base station exceeds the expected range, the base station apparatus can be stably operated by resetting the base station apparatus.

In addition, by detecting a surge using an optical sensor that is not electrically connected to the surge protection circuit in the surge detection circuit of the base station device, the surge detection circuit malfunctions even if the incoming surge voltage or surge current exceeds the expected range. It can be prevented.

In addition, by using an optical sensor that is not electrically connected to the surge protection circuit, the surge detection circuit can be simply implemented.

Hereinafter, the principle of operation of various embodiments will be described in detail with reference to the accompanying drawings. In the following, when it is determined that a detailed description of a known function or configuration related to various embodiments may unnecessarily obscure the gist of the present invention, a detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in various embodiments, which may vary according to intentions or customs of users and operators. Therefore, the definition should be made based on the content throughout this specification.

Hereinafter, the present disclosure describes a technique for detecting the occurrence of a surge in a base station apparatus.

A term that refers to a surge protection device (eg, gas discharge tube, GDT) used in the following description, a term that refers to a change in state (eg, light, vibration, temperature) according to the occurrence of a surge, and a component of the device Terms and the like referring to are exemplified for convenience of description. Accordingly, the present invention is not limited to the terms described below, and other terms having equivalent technical meanings may be used.

1 illustrates a configuration of a surge detection device according to an embodiment.

The surge protection device 140 is connected between the protection line 130 and the ground, and when a surge flows into the protection line 130, the surge protection device 140 transfers the incoming surge to the ground, and the device connected to the protection line 130 (not shown) It can operate so that the surge is not transmitted. The device may be a radio unit (RU) device of a base station installed in a place directly exposed to lightning. The protection line 130 may be a line connecting an external port and at least one internal component (eg, a processor, a memory, etc.) in the device.

In an embodiment, the surge protection device 140 may be configured as a gas discharge tube (GDT). A gas discharge tube is an element in which an open state occurs when a surge below the discharge start voltage is exceeded, and when the discharge start voltage is exceeded, the gas discharge tube conducts instantaneously. When the surge is removed, the gas discharge tube becomes open again. That is, the gas discharge tube has a high impedance when no surge is applied, and a low impedance when a surge is applied. Also, the gas discharge tube may emit light by transitioning from a glow discharge region to an arc-discharge region when a surge is introduced. In the present disclosure, the surge protection device 140 is not limited to a gas discharge tube, and other types of elements may be used.

The surge detection device 110 may detect whether a surge has occurred, count the number of surges when the surge is detected, and transmit the result to the corresponding device (eg, a base station device).

The detection unit 114 of the surge detection device 110 may detect a signal corresponding to a state change of the surge protection device 140 . For example, when a surge flows into the protection line 130, light may be emitted from the surge protection device 140, the ambient temperature (or humidity, etc.) of the surge protection device 140 may change, or vibration or sound may occur. The detection unit 114 of the surge detection device 110 may include at least one of an optical sensor, a temperature sensor, and a vibration sensor capable of detecting a state change of the surge protection device 140 .

The surge determination unit 112 of the surge detection device 110 may determine whether a surge has occurred based on the signal detected from the detection unit 114 and count the number of surge occurrences. For example, if the level of light is higher than the threshold value, the surge determination unit 112 may recognize that the surge has occurred, and if the level of light is lower than the threshold value, it may recognize that the surge has not occurred. In various embodiments, the surge determination unit 112 may determine whether a surge has occurred based on two or more state change signals. For example, when light is emitted and the temperature is higher than a threshold value, it is recognized that a surge has occurred, and even if the light is emitted, when the temperature is lower than the threshold value, it can be recognized that a surge has not occurred.

On the other hand, in order to determine the surge application state, when the surge detection device 110 and the surge protection device 140 are electrically connected, and the voltage and current values of the surge expected during design are out of range, the surge detection device 110 or the protection line 130 All or part of the surge may flow into the device connected to it. That is, the surge protection device 140 is designed to operate within the range of the allowable surge voltage/current of the device, and when an excess surge is introduced outside the range of the allowable surge voltage/current, the surge is detected in whole or in part as it is. may be introduced into device 110 . Accordingly, the corresponding device or the surge sensing device 110 may not operate normally and an error may occur.

However, in the present disclosure, since the surge detection device 110 and the surge protection device 140 are not electrically connected, the surge detection device 110 may not be affected even if the incoming surge is outside the allowable surge voltage/current range.

2 illustrates a detailed configuration of the surge determination unit 112 of the surge sensing device 110 according to an embodiment.

The surge determination unit 112 may include an A/D converter 201 , a comparator 203 , a determination unit 205 , and a counter unit 207 .

The A/D converter 201 may convert an electrical signal corresponding to a physical quantity (eg, light, temperature, vibration, etc.) sensed by the detector 114 into a digital signal.

The comparator 203 may compare a value of the digital signal converted from the A/D converter 201 with a first threshold value (or a second threshold value) and provide the result to the determination unit 205 . Here, the first threshold value is a threshold value for determining whether a surge is generated, and the second threshold value is a threshold value for determining whether a surge is out of an allowable range. The second threshold value may be greater than the first threshold value.

The determination unit 205 may determine whether a surge has occurred according to the comparison result of the comparator 203 . For example, the determination unit 205 may determine that a surge has occurred when the value of the converted digital signal is greater than the value and the first threshold value, and determine that the surge has not occurred when the value of the converted digital signal is smaller than the value and the first threshold value. Also, the determination unit 205 may determine whether the surge is out of an allowable range according to the comparison result of the comparator 203 . For example, if the value of the converted digital signal is greater than the second threshold value, it may be determined that the surge has occurred, and if the value of the converted digital signal is smaller than the value and the second threshold value, it may be determined that the surge has not occurred.

If the determination unit 205 determines that a surge has occurred, the counter unit 207 may count the number of surge occurrences. The number of surge occurrences may be used as a criterion for determining the replacement timing of the surge protection device 140 .

3 is a flowchart illustrating an operation of a surge sensing device according to an exemplary embodiment.

Referring to FIG. 3 , in step 301 , the surge detection device 110 may detect a signal corresponding to a state change of the surge protection device 140 through a sensor. The sensor may be one of an optical sensor, a temperature sensor, and a vibration sensor. The state change of the surge protection device 140 may be at least one of light, vibration, and temperature that may be generated by the surge protection device 140 depending on whether or not a surge is applied.

Thereafter, in step 303 , the surge detection device 110 may determine the number of issuance of a surge introduced into the surge protection device based on the detected signal.

Thereafter, in step 305 , the surge detection device 110 may display whether replacement of the surge protection device is necessary based on the number of surge occurrences. For example, when the number of surge occurrences exceeds the threshold, the surge detection device 110 turns on a status indicator (eg, LED) indicating that it is time to replace the surge protection device, sounds an alarm, or an external interface An external device (via the Internet, for example) may provide information indicating that it is time to replace the surge protection.

4 is a flowchart of an operation of a surge determining unit of a surge sensing device according to an exemplary embodiment.

Referring to FIG. 4 , in step 401 , the surge sensing device 110 may convert an electrical signal corresponding to a sensed physical quantity (eg, light, temperature, vibration, etc.) into a digital signal.

Thereafter, in step 403 , the surge detection device 110 may compare the value of the converted digital signal with a threshold value.

Thereafter, in step 405 , the surge sensing device 110 may determine whether a surge has occurred according to the comparison result. For example, the determination unit 205 may determine that a surge has occurred when the value of the converted digital signal is greater than the value and the first threshold value, and determine that the surge has not occurred when the value of the converted digital signal is smaller than the value and the first threshold value. Also, the determination unit 205 may determine whether the surge is out of an allowable range according to the comparison result of the comparator 203 . For example, if the value of the converted digital signal is greater than the second threshold value, it may be determined that the surge has occurred, and if the value of the converted digital signal is smaller than the value and the second threshold value, it may be determined that the surge has not occurred. Here, the first threshold value is a threshold value for determining whether a surge is generated, and the second threshold value is a threshold value for determining whether a surge is out of an allowable range. The second threshold value may be greater than the first threshold value.

Thereafter, in step 407, the surge detection device 110 may count the number of surge occurrences according to the determination result. The number of surge occurrences may be used as a criterion for determining the replacement time of the surge protection device 140 .

5 shows a configuration of an RU device including a surge protection device and a surge detection device according to an embodiment.

The base station may be divided into a digital unit (DU) device and a radio unit (RU) device. The DU device processes the digital signal of the base station. For example, the DU device is composed of a channel card that encrypts and decrypts a wireless digital signal, and can interwork with the RU device through an optical cable. In addition, DU devices associated with a plurality of base stations may be centrally managed at the switching center.

The RU device processes the RF signal of the base station. For example, the RU device may convert a digital signal received from the DU into an RF signal according to a frequency band and output the RF signal to the antenna, or convert the RF signal received through the antenna into a digital signal and output it to the DU device.

And, in the present disclosure, the RU device and antenna of the base station may be installed in a place directly exposed to lightning, such as a pylon or a rooftop, and the DU of the base station may be installed separately inside a building.

Accordingly, since a surge voltage or surge current may flow into the RU device and the antenna due to lightning, at least one surge protection device (eg, GDT) may be installed inside or outside the RU device. In addition, a surge detection circuit may be additionally installed to predict the replacement timing of the surge protection device.

Referring to Figure 5, the RU device 500 includes two external ports (first and second external ports). In addition, when the RU device 500 is installed on a tower or a roof of a building, it may have a closed enclosure structure to prevent rainwater or moisture from flowing in from the outside.

Although the number of external ports of the RU device 500 shown in FIG. 5 is two, the present disclosure is not limited to two external ports, and the RU device 500 may include one or more external ports.

The external port of the RU device 500 may provide an interface for interworking with external devices (eg, Remote Electrical Tilting (RET), a power supply). In addition, the external port of the RU device 500 may be connected to at least one internal component of the RU device 500 through at least one or more wires (not shown). For example, the first wiring may be a power line or the second wiring may be a control line for interworking with the RET.

In the present disclosure, a gas discharge tube (GDT) may be disposed on a signal line requiring surge protection. For example, in order to prevent a surge from flowing into the RU device 500 through the two wires of the first external port 505, GDTs 510 and 511 may be respectively connected to the two wires. Similarly, in order to prevent a surge from flowing into the RU device 500 through the four wires of the second external port 507, GDT 513, 514, 515, and 516 may be connected to the four wires, respectively.

The GDT 510 may be connected to a first wire (not shown) of the first external port 505 and the GDT 511 may be connected to a second wire (not shown) of the first external port 505 . And, GDT 513 is connected to a first wire (not shown) of the second external port 507, GDT 514 is connected to a second wire (not shown) of the second external port 507, and a third of the second external port 507 GDT 515 may be connected to a wiring (not shown) and GDT 516 may be connected to a fourth wiring (not shown) of the second external port 507 . In addition, each of the GDTs 510, 511, 513, 514, 515, and 516 may be connected to a ground (not shown).

In addition, the surge detection device 512 including the optical sensor may detect whether a surge has been introduced into the GDT by at least one of GDT 510, 511, 513, 514, 515, and 516. For example, when a surge is introduced into the GDT, light is emitted from the GDT, and the surge sensing device 512 may detect light from the GDT according to the surge.

In addition, in order to detect light generated during arc discharge of the GDT, a surge detection device 512 including a photosensor may be disposed near the GDT. At this time, in order to limit the light detected by the photosensor to the light generated by the GDT, partition walls (or shielding walls) 501 and 503 may be installed around the GDT and the photosensor. Since at least one LED (Light-Emitting Diode) (not shown) may be installed inside the RU device for a status indicator, light generated from the at least one LED through the partition walls (or shielding walls) 501 and 503 This can be blocked.

In FIG. 5 , one surge sensing device is disposed in a plurality of GDTs in the vicinity, but the present disclosure is not limited to a plurality of GDTs and one surge sensing device, and one GDT and one surge sensing device are disposed. it might be For example, each surge sensing device may be disposed for each GDT.

6 shows a detailed configuration of an RU device according to an embodiment.

Referring to FIG. 6 , the RU device 600 may include a processor 601 , a surge protection device 610 , a programmable logic device (PLD) 603 , and an electrically erasable programmable read-only memory (EEPROM) 605 . The RU device 500 may further include a power amplifier, not shown. In addition, the RU device 500 may further include an external display device 620 . For example, the external display device 620 may be configured as an LED indicating a status display or a speaker that sounds an alarm.

Also, the RU device 600 may be connected to an external device through an external port. In addition, the processor 601 and the external port of the RU device 600 may be connected by wiring. If the present disclosure is not limited to the connection between the processor 601 and the external port of the RU device 600, depending on the implementation, a plurality of wires between the external port and other components (eg, PLD 603, EEPROM 605) of the RU device 600 can be connected to

In order to block the surge from flowing into the RU device 600 through the external port, a GDT 630 may be disposed between a wiring (hereinafter, a protection line) and the ground to protect it. Although one GDT is illustrated in FIG. 6 , two or more GDTs may be disposed to protect two or more wirings.

When the surge is introduced through the external port, the GDT 630 may operate so that the surge is not transferred to the components of the RU device 600 by transferring the surge to the ground. In addition, the GDT 630 may be replaced by an administrator depending on the lifespan.

The surge detection device 610 may be disposed around the GDT 630 to detect a surge flowing into the GDT 630 and generate an interrupt when the surge is detected. The surge detection device 610 may include an optical sensor 613 for detecting arc light generated from the GDT 630 when a surge is applied, and an analog to digital converter (ADC) 611 for converting an analog signal of the optical sensor 613 into a digital signal.

The surge detection device 610 may generate an interrupt and transmit the interrupt to the PLD 603 when the value of the digital signal in the ADC 611 is higher than a set threshold. As the surge flows into the GDT 630, the interrupt may be a command instructing to execute predetermined processes in response to the surge. For example, according to the generated interrupt, the RU device 600 counts the number of surge occurrences when a surge is introduced, indicates that a surge has occurred, or sounds an alarm when the number of surge occurrences exceeds a threshold value or indicates that GDT 630 replacement is necessary to an external device or external device. It can be provided as a module.

The processor 601 controls overall operations of the RU device 600 . For example, the processor 601 transmits and receives an RF signal through an antenna (not shown). In addition, the processor 601 writes and reads data in the storage unit 220 . To this end, the processor 601 may include at least one processor or microprocessor, or may be a part of the processor. Also, the processor 601 may be referred to as an application processor (AP). In particular, the processor 601 may control various functions of the RU device 600 to process an interrupt related to whether a surge has occurred according to various embodiments described below.

The processor 601 and other components (eg, the surge detection device 610, PLD 603, EEPROM 605) may perform Inter Integrated Circuit (I2C) communication or Serial Peripheral Interface (SPI) communication.

The PLD 603 may be programmed with logic related to some operations of the RU device 600, and may perform some operations of the RU device 600 according to the logic. In the present disclosure, the PLD 603 may control to record the number of surge occurrences in the EEPROM 605 according to an interrupt from the surge detection device 610 .

In addition, the PLD 603 may store the surge generation state in the EEPROM 605 and store the state in a separate internal register so that the processor 601 can know it.

The processor 601 directly handles the interrupt or inquires the internal register status of the PLD 603 to report whether a surge has occurred to the upper system or internally manages it.

According to various embodiments, the interrupt signal related to the surge generation may be generated in the ADC 611 or implemented in the PLD 603. For example, the PLD 603 reads the ADC value periodically, and when the processor 601 is higher than the threshold set in the PLD 603, an interrupt signal may be generated.

The EEPROM 605 may store data such as a basic program, an application program, and setting information for the operation of the RU device 600 . In particular, the EEPROM 605 may store at least one instruction set (eg, an application) for surge detection according to various embodiments. At least one instruction set stored in the EEPROM 605 may be executed by the processor 601 . And the EEPROM 605 provides the stored data according to the request of the processor 601. In addition, the EEPROM 605 may store the number of surge occurrences under the control of the PLD 603. The EEPROM 605 is provided in the RU device 600 and may be referred to as 'internal storage'.

The external display device 620 is not an essential component of the RU device 600, and under the control of the processor 601, the RU device 600 may display the number of surge occurrences when a surge is introduced or may indicate that a surge has occurred.

7 is a flowchart illustrating an operation of an RU device according to another embodiment.

Referring to FIG. 7 , in step 701 , the RU device 600 detects light generated from at least one gas discharge tube (GDT) connected to at least one internal wiring through the surge detection device 610 including an optical sensor. . For example, when a surge such as a lightning strike occurs from the outside, a surge is introduced into the RU device 600 through the external port of the RU device 600, and the introduced surge causes the GDT 630 to transition from the glow region to the arc region to GDT The 630 can be made to emit light.

Thereafter, in step 703 , the RU device 600 may check the detected light level (or light amount). For example, the RU device 800 may check the size of an analog signal corresponding to the monitored light level or digitally convert a signal corresponding to the monitored light level, and check the converted digital signal value.

Thereafter, in step 705 , the RU device 600 may compare whether the detected light intensity is greater than a first threshold, and if greater than the first threshold, proceed to step 707 , and may proceed to step 701 if it is smaller than the first threshold. The first threshold is a threshold for determining whether a surge has occurred.

Thereafter, in step 707 , the RU device 600 may execute an interrupt related to surge generation. That is, the RU device 600 may recognize the surge and perform a procedure for handling the surge. A process of executing an interrupt related to surge generation will be described with reference to FIG. 9 .

Thereafter, in step 709 , the RU device 600 may compare whether the detected light intensity is greater than a second threshold, and if greater than the second threshold, proceed to step 711 , and may terminate the operation if it is less than the second threshold. The second threshold is a threshold for determining whether the surge exceeds an allowable range.

Thereafter, in step 711 , the RU device 600 may perform a system reset. For example, when the surge exceeds the allowable range, the surge is not blocked by the surge protection device, all or part of the surge flows into the RU device 600, and the RU device 600 may malfunction. Therefore, in order to reduce malfunction, the RU device 600 stores the current state information (dynamic system parameters, etc.) and then performs a system reset to return to the initial state, and uses the pre-stored state information to the state immediately before the system reset. can return to

8 is a flowchart illustrating an operation of an RU device according to another embodiment.

Referring to FIG. 8 , in step 801 , the RU device 600 detects light generated from at least one gas discharge tube (GDT) connected to at least one internal wiring through the surge detection device 610 including an optical sensor. .

Thereafter, in step 803 , the RU device 600 may check the detected light level (or light amount). For example, the RU device 800 may check the size of an analog signal corresponding to the monitored light level or digitally convert a signal corresponding to the monitored light level, and check the converted digital signal value.

Thereafter, in step 805 , the RU device 600 may compare whether the detected light intensity is greater than a first threshold, and if greater than the first threshold, proceed to step 807 , and if smaller than the first threshold, proceed to step 801 . The first threshold is a threshold for determining whether a surge has occurred.

Thereafter, in step 807 , the RU device 600 may execute an interrupt related to surge generation. That is, the RU device 600 may recognize the surge and perform a procedure for handling the surge. A process of executing an interrupt related to surge generation will be described with reference to FIG. 9 .

Thereafter, in step 809 , the RU device 600 may report whether the RU device 600 has generated a surge and the number of surges. For example, the RU device 600 may display information indicating that a surge has occurred or may display the number of surge occurrences.

9 is a detailed flowchart of an interrupt related to surge generation according to an embodiment.

Referring to FIG. 9 , in step 901 , the RU device 600 recognizes an interrupt related to surge generation.

Thereafter, in step 903, the RU device 600 may count the number of surge occurrences.

Thereafter, in step 903 , the RU device 600 may store information on whether or not a surge has occurred (eg, status information) and information on the number of surges in the EEPROM 605 .

3 and 7 to 8 are examples of counting the number of surge occurrences by determining whether surges have occurred at each sampling interval.

In another embodiment, the presence or absence of surge and the number of surges may be counted based on signals detected at a plurality of sampling intervals during a predetermined time period as shown in FIG. 10 below.

10 is a flowchart illustrating an operation of an RU device according to another embodiment.

Referring to FIG. 10 , in step 1001, the RU device 600 detects light generated from at least one gas discharge tube (GDT) connected to at least one internal wiring through the surge detection device 610 including an optical sensor. .

Thereafter, in step 1003 , the RU device 600 may check the amount of light sensed during a predefined time period as shown in FIGS. 11(a) to 11(b) below. For example, the RU device 600 may determine whether a low surge continues to occur for a predetermined time or whether a large surge is maintained during a short time period.

Thereafter, in step 1005 , the RU device 600 may determine whether a surge is generated or whether it is outside the expected surge range by considering the size of light and how continuously the light is generated. For example, the RU device 600 may determine that a surge has occurred or that the surge is outside an expected surge range when a surge is continuously detected or a light intensity greater than or equal to a threshold is detected for a predetermined period of time.

Thereafter, in step 1007, if it is determined that a surge has occurred, the RU device 600 may proceed to step 1009 and execute an interrupt related to the surge generation. That is, the RU device 600 may recognize the surge and perform a procedure for handling the surge. The process of executing an interrupt related to surge generation is referred to FIG. 9 .

Then, in step 1011, if the RU device 600 determines that the surge exceeds the allowable range, in step 1013, the RU device 600 may perform a system reset. For example, when the surge exceeds the allowable range, the surge is not blocked by the surge protection device, all or part of the surge flows into the RU device 600, and the RU device 600 may malfunction. Therefore, in order to reduce malfunction, the RU device 600 stores the current state information (dynamic system parameters, etc.) and then performs a system reset to return to the initial state, and uses the pre-stored state information to the state immediately before the system reset. can return to

11 (a) to 11 (b) show the form of a surge voltage or surge current according to an embodiment.

11(a) is a case in which a high surge occurs during a short time period, and FIG. 11(b) is a case in which a low surge occurs during a long time period.

When a high surge occurs during a short time period, the surge may have a large effect on the RU device 600, and even if the surge is low, even if it continues for a long time period, the surge may have a large effect on the RU device 600. Therefore, based on the instantaneous magnitude of the surge voltage/current and the duration of the surge voltage/current, it is possible to determine whether a surge has occurred or whether it is outside the expected surge range.
