Description

Technical Field

[0001] The present invention relates to the technical field of electricity consumption metering, and in particular to a method and system for allocating electricity consumption of equipment of multiple operators. Background Art

[0002] The present invention originates from the indoor coverage construction project of subways and large transportation hubs of the tower company. The present invention is mainly used in new or renovated shared large-scale indoor distributed communication system projects. Since 2014, in accordance with national requirements, the indoor distributed communication systems of new large-scale infrastructure have been led by the tower company for construction, shared by three operators, and all electricity charges for communication equipment are paid by the tower company. Then, the sharing parties send people to use clamp meters to measure the current values ​​of their respective equipment station by station, and share the electricity charges in proportion to the measured current values, and finally settle with the tower company. Due to the rapid increase in the number of large indoor distribution sites, people have to be sent to each indoor distribution site to clamp the flow at regular intervals. In view of the large difference in power consumption between busy and idle times, taking the current clamping data as the benchmark allocation data value for a long period of time is not accurate enough and also consumes a lot of manpower and material resources. In addition, the frequent expansion and renovation of various operators in the later period has led to a large increase and decrease in the number of communication equipment. At present, there is often disagreement on the proportion and amount of electricity bills shared by various companies, resulting in the tower company's advance payment of electricity bills being delayed in time. At the same time, it is also impossible to evaluate the energy conservation and emission reduction effects of various operators and tower companies. Summary of the invention

[0003] The present invention solves the problems of rough electricity fee sharing methods, large errors, high labor costs and long settlement cycles in the current newly built or renovated large-scale indoor distributed systems, and proposes a method and system for sharing electricity consumption of equipment of multiple operators. It is simple and easy to implement through independent metering of phase lines, providing a basis for operators and tower companies to improve energy conservation and emission reduction.

[0004] In order to achieve the above objectives, the following technical solutions are proposed: A method for allocating power consumption of equipment of multiple operators, comprising the following steps: S1, independent phase measurement of each operator’s AC equipment power; S2, independently measures the power consumption of each operator’s DC equipment; S3, measuring the electricity consumption of each operator's AC public power equipment; S4, uploading the AC equipment power, DC equipment power and shared power of each operator to the electricity fee processing system for sharing calculation.

[0005] The present invention is mainly suitable for large-scale indoor distribution scenarios. Since it adopts a physical power supply method of split-phase line and split-DC, it is based on the existing tower company electricity fee management platform and does not involve the investment in newly added complex software and hardware. It can realize the independent metering of electricity fees for each operator in a simple, clear and accurate manner, greatly saving the labor cost of current clamping at the station, shortening the electricity fee settlement cycle, improving the capital turnover rate of electricity fees, and providing real data basis for energy conservation and emission reduction for all parties.

[0006] Preferably, the S1 specifically comprises the following steps: Smart meters are set up for phase-by-phase independent metering according to the power supply mode of each operator's AC equipment. The power supply mode of each operator's AC equipment includes centralized power supply mode and nearby power supply mode.

[0007] The S1 of the present invention specifically comprises the following steps: According to the different power supply methods of AC equipment of each operator, smart meters are set up for independent phase measurement. The power supply methods of AC equipment of each operator include local power supply method and centralized power supply method.

[0008] The equipment used in the remote weak-current room is usually powered by 220V AC, and the following two power supply methods are generally used: the first is a centralized power supply method, that is, a 4-core cable is laid from the computer room to each weak-current room, and the meter is installed in the AC distribution box of the computer room; the other is a decentralized power supply method that takes the main power supply nearby. For large indoor sites that do not require centralized power supply, in order to save professional power investment, the principle of taking power nearby is adopted in each remote weak-current room, and a single-channel intelligent three-phase AC meter is installed separately for measurement. Whether it is a centralized power supply method or a decentralized power supply method that takes the main power supply nearby, it is required to strictly follow the phase-by-phase independent power metering method for power supply. Figure 1 and Figure 2 , K1 and K2 circuit breakers output corresponding electrical quantities P1 (P1's A, B, and C phase electrical quantities are represented by P1a, P1b, and P1c, respectively) and P2 (P2's A, B, and C phase electrical quantities are represented by P2a, P2b, and P2c, respectively), that is, it is stipulated that China Mobile's equipment uses the yellow A phase electricity, China Unicom's equipment uses the green B phase electricity, and China Telecom's equipment uses the red C phase electricity. In this way, the A phase electrical quantities P1a and P2a measured by the three-phase smart meter are the electrical quantities used by China Mobile, the B phase electrical quantities P1b and P2b are the electrical quantities used by China Unicom, and the C phase electrical quantities P1c and P2c are the electrical quantities used by China Telecom.

[0009] Preferably, the S2 specifically comprises the following steps: The DC equipment of each operator uses an independent DC bus, and each DC bus independently measures the DC power consumption through the switching power supply.

[0010] The S2 of the present invention specifically comprises the following steps: An independent DC bus is used to power the DC equipment of each operator. Each independent DC bus independently measures the DC power consumption through the metering module built into the switching power supply.

[0011] The DC output part of the switching power supply is divided into 4 bus outputs, and each DC power is measured and collected separately. The first bus is defined as mobile, and the DC power consumption generated is Pdc1; the second bus is dedicated to China Unicom, and the DC power consumption generated is Pdc2; the third bus is dedicated to China Telecom, and the DC power consumption generated is Pdc3; the fourth bus is spare, and the DC power consumption generated is Pdc4. According to the current actual situation, Pdc4 is vacant and the value is 0. Therefore, the proportion of mobile DC power consumption is βy=Pdc1 / (Pdc1+Pdc2+Pdc3+Pdc4), the proportion of China Unicom DC power consumption is βL=Pdc2 / (Pdc1+Pdc2+Pdc3+Pdc4), and the proportion of China Telecom DC power consumption is βd=Pdc3 / (Pdc1+Pdc2+Pdc3+Pdc4). The DC power used by each bus is automatically uploaded to the tower backend system for processing electricity bills through the dynamic environment monitoring system during each billing cycle.

[0012] Preferably, the S3 specifically comprises the following steps: Obtain the difference between the electricity meter of the power supply bureau or the owner and the total electricity meter of the tower; Obtain the common power loss of the switching power supply itself; The shared electricity consumption of each operator's AC public power equipment = (total output electricity of AC public power equipment + public power loss + difference) × the proportion of DC of each operator.

[0013] The AC power generated in the computer room includes air conditioning, lighting, dynamic environment, the loss of the switching power supply itself, the difference between the power supply bureau or owner's meter and the total meter of the tower, E = the power supply bureau or owner's meter reading minus the total meter reading of the tower, specifically E = P0-(P1+P2+P3+P4). The AC power used by each operator is apportioned according to the statistical proportion of DC power used by each operator. The AC power of equipment such as air conditioning, lighting and dynamic environment is measured by the tower's four-way smart meter, and the output power of circuit breaker K4 is P4. The output power of circuit breaker K3 measured by the four-way smart meter on the tower is P3 minus the total DC power of the switching power supply = (Pdc1+Pdc2+Pdc3+Pdc4), which is the value of the AC loss power Pk of the switching power supply itself. The formula is: Pk=P3-(Pdc1+Pdc2+Pdc3+Pdc4). In the computer room, the AC power that China Mobile should share is Pay=(P4+Pk+E)*βy, the AC power that China Unicom should share is PaL=(P4+Pk+E)*βL, and the AC power that China Telecom should share is Pad=(P4+Pk+E)*βd.

[0014] Preferably, the DC proportion of each operator = the DC power of each operator's DC equipment using an independent DC bus / the total DC power output by the switching power supply.

[0015] Preferably, the electricity fee processing system performs the apportionment calculation according to the following formula: The electricity charge of each operator = (the power consumption of each operator's AC equipment + the power consumption of each operator's DC equipment + the shared power consumption of each operator's AC public power equipment) × the electricity price.

[0016] S4 of the present invention specifically includes the following steps: Based on the above steps S1-S3, in each billing cycle, the power consumption of the mobile company of the large indoor distribution site is Py=P1a+P2a+Pdc1+Pay; the power consumption of China Unicom is PL=P1b+P2b+Pdc2+PaL; the power consumption of the telecommunications company is Pd=P1c+P2c+Pdc3+Pad, and all classified statistical power is uploaded to the tower backend processing power fee system for apportionment calculation. The power fee of each operator = the power consumption of each operator × the power price.

[0017] A multi-operator equipment electricity consumption sharing system adopts the above-mentioned multi-operator equipment electricity consumption sharing method, including several owner-side smart meters for collecting three-phase output electricity of the power supply bureau or the owner and several tower-side smart meters for collecting input electricity of the tower company. The owner-side smart meters and the tower-side smart meters are electrically connected to a control center via a wireless transmission module, the control center is communicatively connected to a switching power supply via the wireless transmission module, and the control center is electrically connected to an electricity fee processing system.

[0018] A multi-operator equipment electricity consumption sharing system adopts the above-mentioned multi-operator equipment electricity consumption sharing method, including a number of tower-side smart meters for collecting tower company input electricity and a number of owner-side smart meters for collecting power supply bureau or owner's three-phase output electricity, the tower-side smart meters and the owner-side smart meters are electrically connected to a control center via a wireless transmission module, the control center is communicatively connected to a switching power supply via the wireless transmission module, and the control center is also electrically connected to an electricity fee processing system.

[0019] Preferably, the power supply modes of the AC equipment of each operator include a centralized power supply mode and a local power supply mode.

[0020] Preferably, when the power supply mode of the AC equipment of each operator is a centralized power supply mode, the owner is provided with one smart meter to collect the three-phase output power of the power supply bureau or the owner. The three-phase output of the power supply bureau or the owner has several outputs through the first air breaker, at least one of which is connected to the AC public power equipment and at least one is connected to the switching power supply. The switching power supply rectifies the AC power and outputs DC power to the DC bus. The switching power supply independently measures the DC power consumption and sends it to the control center; the remaining branches of the three-phase output of the power supply bureau or the owner are connected to the AC distribution box through the second air breaker, and the AC distribution box supplies power to the AC equipment of each operator. The tower side is provided with one smart meter to collect the output power of each phase of each branch after the three-phase output of the power supply bureau or the owner passes through the first air breaker.

[0021] The remote weak-current room of the present invention adopts a centralized power supply method from the integrated machine room, that is, a 4-core cable is laid from the machine room to each weak-current room, and the meter is installed in the AC distribution box of the machine room; China Mobile, China Unicom, and China Telecom strictly supply power in accordance with the phase-by-phase independent metering method, that is, China Mobile uses A-phase electricity, China Unicom uses B-phase electricity, and China Telecom uses C-phase electricity.

The electricity consumption of the near-end machine room is consistent with that of steps S2 and S3 above, and is finally summarized and apportioned by step S4.

[0022] Preferably, when the power supply mode of the AC equipment of each operator is the nearby power supply mode, the owner is provided with several smart meters, at least one of which collects the three-phase output power of the power supply bureau or the owner for the switching power supply and the AC public power equipment. The three-phase output of the power supply bureau or the owner has two outputs through the first air breaker, one of which is connected to the AC public power equipment, and the other is connected to the switching power supply. The switching power supply rectifies the AC power and outputs DC power to the DC bus. The switching power supply independently measures the DC power consumption and sends it to the control center; the three-phase output of the nearest power supply bureau or the owner is separately connected to the AC distribution box through the second air breaker, and the AC distribution box supplies power to the AC equipment of each operator. The tower side is provided with several smart meters, which respectively collect the output power of each phase of each branch after the three-phase output of the power supply bureau or the owner passes through the first air breaker.

[0023] The remote weak current room of the present invention adopts a distributed power supply method of taking power from the nearest power source, that is, each remote weak current room adopts the principle of taking power from the nearest power source, and a single-channel intelligent three-phase AC meter is installed separately for measurement; China Mobile, China Unicom, and China Telecom strictly supply power in accordance with the phase-by-phase independent power metering method, that is, China Mobile uses A-phase electricity, China Unicom uses B-phase electricity, and China Telecom uses C-phase electricity.

The power supply methods of AC equipment of each operator include local power supply method and centralized power supply method.

[0028] The equipment used in the remote weak-current room is usually powered by 220V AC, and the following two power supply methods are generally used: the first is a centralized power supply method, that is, a 4-core cable is laid from the computer room to each weak-current room, and the meter is installed in the AC distribution box of the computer room; the other is a decentralized power supply method that takes the main power supply nearby. For large indoor sites that do not require centralized power supply, in order to save professional power investment, the principle of taking power nearby is adopted in each remote weak-current room, and a single-channel intelligent three-phase AC meter is installed separately for measurement. Whether it is a centralized power supply method or a decentralized power supply method that takes the main power supply nearby, it is required to strictly follow the phase-by-phase independent power metering method for power supply. Figure 1 and Figure 2 , K1 and K2 circuit breakers output corresponding electrical quantities P1 (P1's A, B, and C phase electrical quantities are represented by P1a, P1b, and P1c, respectively) and P2 (P2's A, B, and C phase electrical quantities are represented by P2a, P2b, and P2c, respectively), that is, it is stipulated that China Mobile's equipment uses the yellow A phase electricity, China Unicom's equipment uses the green B phase electricity, and China Telecom's equipment uses the red C phase electricity. In this way, the A phase electrical quantities P1a and P2a measured by the three-phase smart meter are the electrical quantities used by China Mobile, the B phase electrical quantities P1b and P2b are the electrical quantities used by China Unicom, and the C phase electrical quantities P1c and P2c are the electrical quantities used by China Telecom.

[0029] S2: Independently measure the power consumption of each operator's DC equipment in the power consumption area of ​​the proximal equipment room; The S2 of the present invention specifically comprises the following steps: An independent DC bus is used to power the DC equipment of each operator. Each independent DC bus independently measures the DC power consumption through the metering module built into the switching power supply.

[0030] The DC output part of the switching power supply is divided into 4 bus outputs, and each DC power is measured and collected separately. The first bus is defined as mobile, and the DC power consumption generated is Pdc1; the second bus is dedicated to China Unicom, and the DC power consumption generated is Pdc2; the third bus is dedicated to China Telecom, and the DC power consumption generated is Pdc3; the fourth bus is spare, and the DC power consumption generated is Pdc4. According to the current actual situation, Pdc4 is vacant and the value is 0. Therefore, the proportion of mobile DC power consumption is βy=Pdc1 / (Pdc1+Pdc2+Pdc3+Pdc4), the proportion of China Unicom DC power consumption is βL=Pdc2 / (Pdc1+Pdc2+Pdc3+Pdc4), and the proportion of China Telecom DC power consumption is βd=Pdc3 / (Pdc1+Pdc2+Pdc3+Pdc4). The DC power used by each bus is automatically uploaded to the tower backend system for processing electricity bills through the dynamic environment monitoring system during each billing cycle.

[0031] S3: Allocate electricity consumption to the public AC equipment of each operator in the power consumption area of ​​the proximal equipment room; The AC power generated in the computer room includes air conditioning, lighting, dynamic environment, the loss of the switching power supply itself, the difference between the power supply bureau or owner's meter and the total meter of the tower, E = the power supply bureau or owner's meter reading minus the total meter reading of the tower, specifically E = P0-(P1+P2+P3+P4). The AC power used by each operator is apportioned according to the statistical proportion of DC power used by each operator. The AC power of equipment such as air conditioning, lighting and dynamic environment is measured by the tower's four-way smart meter, and the output power of circuit breaker K4 is P4. The output power of circuit breaker K3 measured by the four-way smart meter on the tower is P3 minus the total DC power of the switching power supply = (Pdc1+Pdc2+Pdc3+Pdc4), which is the value of the AC loss power Pk of the switching power supply itself. The formula is: Pk=P3-(Pdc1+Pdc2+Pdc3+Pdc4). In the computer room, the AC power that China Mobile should share is Pay=(P4+Pk+E)*βy, the AC power that China Unicom should share is PaL=(P4+Pk+E)*βL, and the AC power that China Telecom should share is Pad=(P4+Pk+E)*βd.

[0032] S4: Summarize the shared electricity of each operator from steps S1 to S3, and upload all classified statistical electricity to the tower backend system for processing electricity bills for sharing calculation.

[0033] S4 of the present invention specifically includes the following steps: Based on the above steps S1-S3, in each billing cycle, the power consumption of the mobile company of the large indoor distribution site is Py=P1a+P2a+Pdc1+Pay; the power consumption of China Unicom is PL=P1b+P2b+Pdc2+PaL; the power consumption of the telecommunications company is Pd=P1c+P2c+Pdc3+Pad, and all classified statistical power is uploaded to the tower backend processing power fee system for apportionment calculation. The power fee of each operator = the power consumption of each operator × the power price.

[0034] The present invention is mainly suitable for large-scale indoor distribution scenarios. Since it adopts a physical power supply method of split-phase line and split-DC, it is based on the existing tower company electricity fee management platform and does not involve the investment in newly added complex software and hardware. It can realize the independent metering of electricity fees for each operator in a simple, clear and accurate manner, greatly saving the labor cost of current clamping at the station, shortening the electricity fee settlement cycle, improving the capital turnover rate of electricity fees, and providing real data basis for energy conservation and emission reduction for all parties.

[0035] This embodiment proposes a multi-operator equipment power consumption sharing system, which adopts the above-mentioned multi-operator equipment power consumption sharing method, including several tower-side smart meters for collecting input power from the tower company and several owner-side smart meters for collecting three-phase output power from the power supply bureau or the owner, wherein the tower-side smart meters and the owner-side smart meters are electrically connected to the control center through a wireless transmission module, and the control center is connected to the switch power supply through a wireless transmission module, and the control center is also electrically connected to the electricity fee processing system. The near-end DC power supply of the integrated computer room at a large indoor distribution site is independently metered by a branch line, and the AC power supply used independently at the computer room end or the far end is independently metered by a phase-split line, which is summarized by a remote meter reading system, and the shared AC power such as lighting, air conditioning, line loss, etc. in the computer room is shared according to the proportion of DC power consumption of each company, thereby realizing independent power supply metering of each operator's communication equipment.

[0036] Generally, the communication equipment of large-scale indoor distribution sites is mainly installed in the near-end integrated machine room and the various weak current rooms or weak current wells at the far end. The independent metering method adopted in the near-end integrated machine room is as follows: the three-phase AC power is measured by the power supply department or the owner's meter, and then connected to the AC distribution box in the tower machine room. A four-way intelligent three-phase AC meter is installed in the AC distribution box. After being measured by this meter, the output is generally divided into several routes, one of which is a three-phase access to the switching power supply; if there is a large-scale indoor distribution with centralized power supply requirements, one route is also required to be allocated to the far-end weak current room or tunnel node; the remaining routes are connected to other AC power equipment such as air conditioners, lighting, and dynamic rings.

[0037] Embodiment 2: Based on Example 1, this embodiment proposes a method for allocating power consumption of equipment of multiple operators from a centralized power supply mode in an integrated computer room, including the following steps: S1: independently measuring the power consumption of each operator's AC equipment in the remote weak current room or tunnel equipment power consumption area; the S1 of the present invention specifically includes the following steps: According to the different power supply methods of AC equipment of each operator, smart meters are set up for independent phase measurement. The power supply methods of AC equipment of each operator include local power supply method and centralized power supply method.

[0038] The equipment used in the remote weak-current room is usually powered by 220V AC, and the following two power supply methods are generally used: the first is a centralized power supply method, that is, a 4-core cable is laid from the computer room to each weak-current room, and the meter is installed in the AC distribution box of the computer room; the other is a decentralized power supply method that takes the main power supply nearby. For large indoor sites that do not require centralized power supply, in order to save professional power investment, the principle of taking power nearby is adopted in each remote weak-current room, and a single-channel intelligent three-phase AC meter is installed separately for measurement. Whether it is a centralized power supply method or a decentralized power supply method that takes the main power supply nearby, it is required to strictly follow the phase-by-phase independent power metering method for power supply. Figure 1 and Figure 2 , K1 and K2 circuit breakers output corresponding electrical quantities P1 (P1's A, B, and C phase electrical quantities are represented by P1a, P1b, and P1c, respectively) and P2 (P2's A, B, and C phase electrical quantities are represented by P2a, P2b, and P2c, respectively), that is, it is stipulated that China Mobile's equipment uses the yellow A phase electricity, China Unicom's equipment uses the green B phase electricity, and China Telecom's equipment uses the red C phase electricity. In this way, the A phase electrical quantities P1a and P2a measured by the three-phase smart meter are the electrical quantities used by China Mobile, the B phase electrical quantities P1b and P2b are the electrical quantities used by China Unicom, and the C phase electrical quantities P1c and P2c are the electrical quantities used by China Telecom.

[0039] S2: Independently measure the power consumption of each operator's DC equipment in the power consumption area of ​​the proximal equipment room; The S2 of the present invention specifically comprises the following steps: An independent DC bus is used to power the DC equipment of each operator. Each independent DC bus independently measures the DC power consumption through the metering module built into the switching power supply.

[0040] The DC output part of the switching power supply is divided into 4 bus outputs, and each DC power is measured and collected separately. The first bus is defined as mobile, and the DC power consumption generated is Pdc1; the second bus is dedicated to China Unicom, and the DC power consumption generated is Pdc2; the third bus is dedicated to China Telecom, and the DC power consumption generated is Pdc3; the fourth bus is spare, and the DC power consumption generated is Pdc4. According to the current actual situation, Pdc4 is vacant and the value is 0. Therefore, the proportion of mobile DC power consumption is βy=Pdc1 / (Pdc1+Pdc2+Pdc3+Pdc4), the proportion of China Unicom DC power consumption is βL=Pdc2 / (Pdc1+Pdc2+Pdc3+Pdc4), and the proportion of China Telecom DC power consumption is βd=Pdc3 / (Pdc1+Pdc2+Pdc3+Pdc4). The DC power used by each bus is automatically uploaded to the tower backend system for processing electricity bills through the dynamic environment monitoring system during each billing cycle.

[0041] S3: Allocate electricity consumption to the public AC equipment of each operator in the power consumption area of ​​the proximal equipment room; The AC power generated in the computer room includes air conditioning, lighting, dynamic environment, the loss of the switching power supply itself, the difference between the power supply bureau or owner's meter and the total meter of the tower, E = the power supply bureau or owner's meter reading minus the total meter reading of the tower, specifically E = P0-(P1+P2+P3+P4). The AC power used by each operator is apportioned according to the statistical proportion of DC power used by each operator. The AC power of equipment such as air conditioning, lighting and dynamic environment is measured by the tower's four-way smart meter, and the output power of circuit breaker K4 is P4. The output power of circuit breaker K3 measured by the four-way smart meter on the tower is P3 minus the total DC power of the switching power supply = (Pdc1+Pdc2+Pdc3+Pdc4), which is the value of the AC loss power Pk of the switching power supply itself. The formula is: Pk=P3-(Pdc1+Pdc2+Pdc3+Pdc4). In the computer room, the AC power that China Mobile should share is Pay=(P4+Pk+E)*βy, the AC power that China Unicom should share is PaL=(P4+Pk+E)*βL, and the AC power that China Telecom should share is Pad=(P4+Pk+E)*βd.

[0043] S4 of the present invention specifically includes the following steps: Based on the above steps S1-S3, in each billing cycle, the power consumption of the mobile company of the large indoor distribution site is Py=P1a+P2a+Pdc1+Pay; the power consumption of China Unicom is PL=P1b+P2b+Pdc2+PaL; the power consumption of the telecommunications company is Pd=P1c+P2c+Pdc3+Pad, and all classified statistical power is uploaded to the tower backend processing power fee system for apportionment calculation. The power fee of each operator = the power consumption of each operator × the power price.

[0044] The present invention is mainly suitable for large-scale indoor distribution scenarios. Since it adopts a physical power supply method of split-phase line and split-DC, it is based on the existing tower company electricity fee management platform and does not involve the investment in newly added complex software and hardware. It can realize the independent metering of electricity fees for each operator in a simple, clear and accurate manner, greatly saving the labor cost of current clamping at the station, shortening the electricity fee settlement cycle, improving the capital turnover rate of electricity fees, and providing real data basis for energy conservation and emission reduction for all parties.

[0045] This embodiment proposes a multi-operator equipment power consumption sharing system, which adopts the above-mentioned multi-operator equipment power consumption sharing method, including several tower-side smart meters for collecting the input power of the tower company and several owner-side smart meters for collecting the three-phase output power of the power supply bureau or the owner. The tower-side smart meters and the owner-side smart meters are electrically connected to the control center through a wireless transmission module, and the control center is connected to the switching power supply through the wireless transmission module. The control center is also electrically connected to the electricity fee processing system.

[0046] Embodiment 3: This embodiment is based on the power supply mode of the principle of close power supply in embodiment 1, and proposes a method for allocating power consumption of equipment of multiple operators, including the following steps: S1: independently measuring the power consumption of each operator's AC equipment in the remote weak current room or tunnel equipment power consumption area; the S1 of the present invention specifically includes the following steps: According to the different power supply methods of AC equipment of each operator, smart meters are set up for independent phase measurement. The power supply methods of AC equipment of each operator include local power supply method and centralized power supply method.

[0047] The equipment used in the remote weak-current room is usually powered by 220V AC, and the following two power supply methods are generally used: the first is a centralized power supply method, that is, a 4-core cable is laid from the computer room to each weak-current room, and the meter is installed in the AC distribution box of the computer room; the other is a decentralized power supply method that takes the main power supply nearby. For large indoor sites that do not require centralized power supply, in order to save professional power investment, the principle of taking power nearby is adopted in each remote weak-current room, and a single-channel intelligent three-phase AC meter is installed separately for measurement. Whether it is a centralized power supply method or a decentralized power supply method that takes the main power supply nearby, it is required to strictly follow the phase-by-phase independent power metering method for power supply. Figure 1 and Figure 2, K1 and K2 circuit breakers output corresponding electrical quantities P1 (P1's A, B, and C phase electrical quantities are represented by P1a, P1b, and P1c, respectively) and P2 (P2's A, B, and C phase electrical quantities are represented by P2a, P2b, and P2c, respectively), that is, it is stipulated that China Mobile's equipment uses the yellow A phase electricity, China Unicom's equipment uses the green B phase electricity, and China Telecom's equipment uses the red C phase electricity. In this way, the A phase electrical quantities P1a and P2a measured by the three-phase smart meter are the electrical quantities used by China Mobile, the B phase electrical quantities P1b and P2b are the electrical quantities used by China Unicom, and the C phase electrical quantities P1c and P2c are the electrical quantities used by China Telecom.

[0048] S2: Independently measure the power consumption of each operator's DC equipment in the power consumption area of ​​the proximal equipment room; The S2 of the present invention specifically comprises the following steps: An independent DC bus is used to power the DC equipment of each operator. Each independent DC bus independently measures the DC power consumption through the metering module built into the switching power supply.

[0049] The DC output part of the switching power supply is divided into 4 bus outputs, and each DC power is measured and collected separately. The first bus is defined as mobile, and the DC power consumption generated is Pdc1; the second bus is dedicated to China Unicom, and the DC power consumption generated is Pdc2; the third bus is dedicated to China Telecom, and the DC power consumption generated is Pdc3; the fourth bus is spare, and the DC power consumption generated is Pdc4. According to the current actual situation, Pdc4 is vacant and the value is 0. Therefore, the proportion of mobile DC power consumption is βy=Pdc1 / (Pdc1+Pdc2+Pdc3+Pdc4), the proportion of China Unicom DC power consumption is βL=Pdc2 / (Pdc1+Pdc2+Pdc3+Pdc4), and the proportion of China Telecom DC power consumption is βd=Pdc3 / (Pdc1+Pdc2+Pdc3+Pdc4). The DC power used by each bus is automatically uploaded to the tower backend system for processing electricity bills through the dynamic environment monitoring system during each billing cycle.

[0050] S3: Allocate electricity consumption to the public AC equipment of each operator in the power consumption area of ​​the proximal equipment room; The AC power generated in the computer room includes air conditioning, lighting, dynamic environment, the loss of the switching power supply itself, the difference between the power supply bureau or owner's meter and the total meter of the tower, E = the power supply bureau or owner's meter reading minus the total meter reading of the tower, specifically E = P0-(P1+P2+P3+P4). The AC power used by each operator is apportioned according to the statistical proportion of DC power used by each operator. The AC power of equipment such as air conditioning, lighting and dynamic environment is measured by the tower's four-way smart meter, and the output power of circuit breaker K4 is P4. The output power of circuit breaker K3 measured by the four-way smart meter on the tower is P3 minus the total DC power of the switching power supply = (Pdc1+Pdc2+Pdc3+Pdc4), which is the value of the AC loss power Pk of the switching power supply itself. The formula is: Pk=P3-(Pdc1+Pdc2+Pdc3+Pdc4). In the computer room, the AC power that China Mobile should share is Pay=(P4+Pk+E)*βy, the AC power that China Unicom should share is PaL=(P4+Pk+E)*βL, and the AC power that China Telecom should share is Pad=(P4+Pk+E)*βd.

[0051] S4: Summarize the shared electricity of each operator from steps S1 to S3, and upload all classified statistical electricity to the tower backend system for processing electricity bills for sharing calculation.

[0052] S4 of the present invention specifically includes the following steps: Based on the above steps S1-S3, in each billing cycle, the power consumption of the mobile company of the large indoor distribution site is Py=P1a+P2a+Pdc1+Pay; the power consumption of China Unicom is PL=P1b+P2b+Pdc2+PaL; the power consumption of the telecommunications company is Pd=P1c+P2c+Pdc3+Pad, and all classified statistical power is uploaded to the tower backend processing power fee system for apportionment calculation. The power fee of each operator = the power consumption of each operator × the power price.

[0053] The present invention is mainly suitable for large-scale indoor distribution scenarios. Since it adopts a physical power supply method of split-phase line and split-DC, it is based on the existing tower company electricity fee management platform and does not involve the investment in newly added complex software and hardware. It can realize the independent metering of electricity fees for each operator in a simple, clear and accurate manner, greatly saving the labor cost of current clamping at the station, shortening the electricity fee settlement cycle, improving the capital turnover rate of electricity fees, and providing real data basis for energy conservation and emission reduction for all parties.

[0054] This embodiment proposes a multi-operator equipment power consumption sharing system, which adopts the above-mentioned multi-operator equipment power consumption sharing method, including several tower-side smart meters for collecting the input power of the tower company and several owner-side smart meters for collecting the three-phase output power of the power supply bureau or the owner. The tower-side smart meters and the owner-side smart meters are electrically connected to the control center through a wireless transmission module, and the control center is connected to the switching power supply through the wireless transmission module. The control center is also electrically connected to the electricity fee processing system. Reference Figure 2 In this embodiment, the remote weak-current room adopts a distributed power supply mode of nearby power supply, that is, the principle of nearby power supply is adopted in each remote weak-current room, and a single-channel intelligent three-phase AC meter is installed for measurement; China Mobile, China Unicom, and China Telecom strictly supply power in accordance with the phase-by-phase independent power metering method, that is, China Mobile uses A-phase electricity, China Unicom uses B-phase electricity, and China Telecom uses C-phase electricity. In each billing cycle, the sum of the A-phase electricity of each weak-current room meter is the electricity used by China Mobile's remote weak-current room, the sum of the B-phase electricity is the electricity used by China Unicom's remote weak-current room, and the sum of the C-phase electricity is the electricity used by China Telecom's remote weak-current room. The power consumption of the near-end computer room is consistent with the above steps S2 and S3, and is finally summarized and apportioned by step S4.
