[0025] According to an embodiment of this application, an embodiment of a base station power generation and signal acquisition method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0026] Figure 1 This is a base station power generation and signal acquisition device according to an embodiment of this application, such as... Figure 1 As shown, the device includes:

[0027] The first AC relay 10 is used to monitor the on / off status of the mains power supply. The two input terminals of the first AC relay 10 are connected to the first phase line and the neutral line of the mains power supply, respectively. The output terminal of the first AC relay 10 is connected to the first switch of the indoor baseband processing unit. The first phase line is one of the three phase lines drawn from the mains power supply.

[0028] The Building Baseband Unit (BBU) is the baseband processing unit of the base station, providing external interfaces and performing functions such as system resource management, operation and maintenance, and environmental monitoring. Optionally, the first phase line can be a C-phase line drawn from the mains power supply, the first switch is dry contact 1, the first AC relay 10 is AC relay 1, and the two input terminals of the first AC relay 10 are input terminal 1 and input terminal 2.

[0029] The second AC relay 12 is used to monitor the power generation of the generator. The two input terminals of the second AC relay 12 are connected to the second phase line and the neutral line of the generator, respectively. The output terminal of the second AC relay 12 is connected to the second switch of the indoor baseband processing unit. The second phase line is one of the three phase lines drawn from the generator.

[0030] Optionally, the second phase line can be the C phase line drawn from the generator, the second switch is dry contact 2, the second AC relay 12 is AC relay 2, and the two input terminals of the second AC relay 12 are input terminal 3 and input terminal 4.

[0031] Power supply 14 is connected to the first AC relay 10 and the second AC relay 12, and is used to supply power to the first AC relay 10 and the second AC relay 12.

[0032] Optionally, power supply 14 can be powered by dry cell batteries to power the two AC relays.

[0033] By collecting data on the status of the mains power supply and the generator, the power generation duration of the base station can be statistically analyzed. This achieves the technical effects of visually monitoring the power generation status of the base station, accurately calculating the power generation duration, low risk, low energy consumption, low cost, and convenient connection.

[0034] According to an optional embodiment of this application, when the circuit formed by the first AC relay 10 and the first phase line and neutral line is connected, the first switch is turned on, indicating that the mains power supply is in a connected state; when the circuit formed by the first AC relay 10 and the first phase line and neutral line is disconnected, the first switch is turned off, indicating that the mains power supply is in a disconnected state; when the circuit formed by the second AC relay 12 and the second phase line and neutral line is connected, the second switch is turned on, indicating that the generator is in a generating state; when the circuit formed by the second AC relay 12 and the second phase line and neutral line is disconnected, the second switch is turned off, indicating that the generator is in a de-energized state.

[0035] Base station communication equipment rooms typically use a three-phase four-wire 380V power supply, connected to an AC distribution panel. The four wires consist of three live wires and one neutral wire. The three live wires are phases A, B, and C. The voltage between the neutral wire and each live wire is 220V, while the voltage between any two live wires is 380V. This device uses AC relay 1 and AC relay 2 to generate power and obtain signal. The specific circuit diagram is shown below. Figure 2 As shown.

[0036] AC relay 1 serves as a monitoring device for the on / off state of the mains power. AC relay 1 uses a circuit consisting of the first phase line and the neutral line as the method for determining the on / off state of AC power. The two ends of the AC input of AC relay 1 are connected to the first phase line and the neutral line, respectively. When the mains power is on, the voltage between the first phase line and the neutral line is 220V. This forms a closed circuit through the coil of AC relay 1, energizing the coil and generating a magnetic field that attracts the contacts to close. The 1.5V dry cell battery at the output end conducts through the BBU dry contact 1, and the input signal changes from 0 to 1. Conversely, when the mains power is off, the voltage between the first phase line and the neutral line becomes 0V. The coil of AC relay 1 loses its magnetic field, the dry cell battery at the output end disconnects from the BBU dry contact 1, and the input signal changes from 1 to 0.

[0037] AC relay 2, serving as a condition determination device for AC power generation, operates on a similar principle to AC relay 1. AC relay 2 uses a circuit consisting of the second phase line and the neutral line as the method for determining the on / off state of AC power. The two ends of the AC input of AC relay 2 are connected to the second phase line and the neutral line, respectively; that is, the second phase line and the neutral line are connected to input terminals 3 and 4 of AC relay 2, respectively. When the generator is generating electricity, the coil of AC relay 2 is energized, and the BBU dry contact 2 is closed; when the generator is de-energized, the coil of AC relay 2 is open, and the BBU dry contact 2 is disconnected.

[0038] It is particularly important to note that, according to the specifications, the input terminals of the AC distribution panel must be disconnected during power generation, and the AC generator must be connected to a dedicated generator interface. Therefore, input terminals 3 and 4 of AC relay 2 need to be connected to the back end of the dedicated AC generator interface to ensure effective monitoring of the power generation status.

[0039] According to another optional embodiment of this application, the first AC relay 10 and the second AC relay 12 are changeover AC relays.

[0040] The device provided in this application uses two AC relays, namely AC relay 1 and AC relay 2 (the specifications of the two AC relays can be 5A250AC / 5A28VDC). There are three basic types of relay contacts: normally open (H-type), where the two contacts are open when the coil is not energized and closed when energized; normally closed (D-type), where the two contacts are closed when the coil is not energized and open when energized; and changeover type (Z-type), which is a contact group type with three contacts: a moving contact in the middle and one stationary contact at the top and bottom. In the changeover type AC relay, when the coil is not energized, the moving contact is open with one of the stationary contacts and closed with the other; when the coil is energized, the moving contact moves, making the previously open contact closed and the previously closed contact open, thus achieving the changeover purpose. Considering that the input of this device is 220V AC, and since the output characteristics of 220V AC are high and low levels, a changeover type AC relay is used.

[0041] According to another optional embodiment of this application, the device further includes: a first fuse located between the first AC relay 10 and the first phase line, used to protect the base station power generation and signal acquisition device in the event of excessive input voltage of the mains power supply.

[0042] It should be noted that, in order to reliably monitor the on / off status of the mains power and avoid misjudgments caused by interference from generator signals, the input terminal of AC relay 1 must be connected to the input terminal of the AC distribution panel, and should be before the main control switch of the AC distribution panel. Furthermore, to prevent damage to AC relay 1 or short circuits due to excessive instantaneous voltage, a 220V / 1A fuse is installed at the input terminal of AC relay 1 as a safety measure.

[0043] In some optional embodiments of this application, the device further includes: a second fuse located between the second AC relay 12 and the second phase line, used to protect the base station power generation signal acquisition device in the event of excessive input voltage of the generator.

[0044] To prevent damage or short circuits to AC relay 2 due to excessive instantaneous voltage, a 220V / 1A fuse is also installed at the input terminal of AC relay 2 as a safety measure.

[0045] It should be noted that this application also uses connecting cables to connect the internal AC relay 1, AC relay 2, and dry cell battery of the device, as well as to make external connections with BBU dry contact 1, BBU dry contact 2, first phase line, second phase line, and neutral line.

[0046] The device provided in this application requires only two AC relays, a 1.5V dry cell battery pack, several connecting cables, and fuses. This device has few electronic components, is easy to manufacture and produce, and has advantages such as simple composition, reliability, and low cost. Since all components are physical devices, logic judgment and state transition functions can rely on network management equipment, eliminating the need for independent power supplies, thus reducing the risk of damage and ensuring high reliability. Furthermore, this device provides four input interfaces, one for connecting to AC mains power and the other for connecting to a generator, allowing direct parallel connection to an AC distribution panel without occupying additional input terminals. Simultaneously, the four outputs are RJ45 interfaces, making connection convenient and simple.

[0047] Figure 3 This is a flowchart of a base station power generation and signal acquisition method according to an embodiment of this application, such as... Figure 3 As shown, the method includes the following steps:

[0048] Step S302: Obtain the power supply status of the mains power source and the status of the generator through the base station power generation signal acquisition device;

[0049] Step S304: Determine the power generation duration of the base station based on the power supply status of the mains power supply and the status of the generator. The power generation duration of the base station includes the power generation duration of the generator in the base station and the discharge duration of the battery pack in the base station.

[0050] Optionally, the battery pack can be a rechargeable battery.

[0051] According to an optional embodiment of this application, before executing step S304 to determine the power generation duration of the base station based on the power supply status of the mains power supply and the generator status, the method further includes: determining a first moment, wherein the first moment is when the mains power supply status is disconnected, the generator status is de-energized, and the battery pack is discharging; determining a second moment, wherein the second moment is when the mains power supply status is disconnected, the generator status is de-energized, and the battery pack is de-energized; determining a third moment, wherein the third moment is when the mains power supply status is disconnected, the generator status is generating, and the battery pack is de-energized; and determining a fourth moment, wherein the fourth moment is when the mains power supply status is on, the generator status is de-energized, and the battery pack is de-energized.

[0052] Optionally, the first time point is Td, the second time point is Tj, the third time point is Tf, and the fourth time point is Tz. When the mains power is normal, the BBU dry contact 1, dry contact 2, and the station failure alarm input are 111; when the mains power fails, the generator does not generate electricity and the battery discharges, the BBU dry contact 1, BBU dry contact 2, and the station failure alarm input are 001, and the time is recorded as Td; if generation continues without interruption, the battery is depleted, the BBU dry contact 1, dry contact 2, and the station failure alarm input are 000, and the time is recorded as Tj; if generation begins, the input is 011, and the time is recorded as Tf; when the mains power is restored, the input is 111, and the time is recorded as Tz. The above-mentioned power outage time Td, generation time Tf, station failure time Tj, and mains power restoration time Tz can be statistically analyzed through the connected network management equipment. The flowchart of this embodiment is shown below. Figure 4 As shown.

[0053] According to another optional embodiment of this application, step S304 determines the power generation duration of the base station based on the power supply status of the mains power supply and the status of the generator, including: when the mains power supply is turned on and the generator stops generating power, determining the power generation duration of the generator based on the fourth time and the third time; when the mains power supply is not turned on and the battery pack is discharging and the generator stops generating power, determining the power generation duration of the generator based on the first time and the third time; and determining the discharge duration of the battery pack based on the second time and the first time.

[0054] When the mains power is restored and the generator stops generating electricity, the generator's power generation time is the mains power restoration time Tz minus the power generation time Tf. If the mains power is not restored and the battery continues to generate electricity, the generator's power generation time can also be calculated as the power outage time Td2 minus the power generation time Tf. The battery's discharge time is the station outage time Tj minus the power outage time Td.

[0055] The device used in this application addresses the pain point of telecommunications companies being unable to monitor the power generation status of base stations by utilizing the state transitions of BBU dry contacts. This device is simple, reliable, low-cost, and easy to connect; it can directly utilize existing network management equipment to calculate power generation duration; it can accurately track the power generation and de-energization status of the base station, and the records of each status are visually verifiable. This device collects data on the base station's mains power status, battery discharge status, and generator operating status, and uses network management equipment to monitor the base station's power generation status in a timely and visual manner through changes in alarm status, achieving the goal of power generation and signal reception.

[0058] The network management device 52 is connected to the base station power generation and signal acquisition device 50 and is used to display the power generation duration of the base station.

[0059] According to an optional embodiment of this application, the network management device 52 is connected to the base station power generation and signal acquisition device 50 via an RJ45 interface, supporting a total of four signal inputs in pairs. The specific connection method is as follows: Figure 6 As shown, first reliably connect the RJ45 connector to the output terminal of this device, and then insert it into the interface of the network management device 52. The interface of the network management device 52 adopts a switch-type (on / off) judgment method, and the alarm information policy for the on / off state can be manually defined on the network management device 52. For example, it can be set to the initial state as on and the alarm state as off. Under this setting, when dry contact 1 is on, there is no alarm on the network management device 52; when dry contact 1 is off, the network management device 52 displays a custom alarm, and vice versa. The configuration method of dry contact 2 is the same as that of dry contact 1. Specifically, the network management device 52 is configured as follows: configure port 0 of dry contact 1 and port 1 of dry contact 2 as alarms, configure the corresponding alarm number, and then set the alarm name, category, and alarm registration.

[0060] The device provided in this application relies on the network management device 52 for data acquisition and presentation, eliminating the need for a new network management device 52 and avoiding the use of transmission equipment interfaces. Because the BBU and network management device 52 have relatively accurate clocks and alarm response capabilities, the power generation / disruption status based on alarm status statistics is also relatively accurate. Furthermore, the alarm data from the network management device 52 is visible and searchable, and can be directly exported for data processing to calculate the power generation duration.
