Description

Technical Field

[0001] This algorithm mainly involves computer technology and the principle of energy consumption sharing among departments. Background Art

[0002] With the continuous development and improvement of medical technology, the scale of hospital construction is getting larger and larger, and with it comes the management of more and more hospital departments. How to quickly and effectively understand the energy consumption of each hospital department, conduct energy consumption performance analysis, and thus maximize the emergency benefits of the hospital has become a key issue.

[0003] Currently, many hospitals still implement traditional departmental energy management methods, requiring dedicated staff to manually read and record energy meters in relevant department rooms. This approach is inefficient, prone to errors, and presents numerous problems. In real-world hospital environments, the energy consumption relationships between departments are often extremely complex. For example, it is common for a department to have multiple rooms, each with multiple meters, and a single meter to be allocated to multiple rooms. These complex relationships between energy meters and rooms make it extremely difficult and unrealistic to manually calculate accurate values ​​using traditional building energy consumption algorithms, even with defined relationships between meters and rooms and the allocation ratios for each meter. Inaccurate departmental energy consumption data can ultimately lead to incorrect decisions by hospital management.

[0004] Therefore, there is an urgent need for a computer-related algorithm to accurately calculate the energy consumption of each department. Summary of the Invention

[0005] To overcome and address the aforementioned shortcomings and deficiencies in traditional Chinese medicine hospitals, the present invention provides a hospital department energy consumption algorithm system based on meter allocation. The present invention aims to address the existing problems of hospitals' energy consumption being unable to be scientifically allocated to corresponding departments, resulting in unclear and difficult-to-track allocations, inability to implement departmental energy consumption allocations, and inability to implement energy consumption performance.

[0006] In order to solve the above technical problems, the present invention needs to take measures to modify the existing energy consumption architecture of the hospital. The main contents are as follows: First, we need to clarify the overall framework diagram of the energy consumption of the hospital departments. We divide the energy consumption metering areas of the hospital into four types: hospital, building, location and room. Generally, a hospital is set as the first level, and the room is fixed as the last level. There are no other setting rules for buildings and locations. At the same time, each room is set to have its own department.

[0007] The connection between the metering area and common meters (electricity meter, water meter, gas meter) meets the following rules: one metering area is allowed to connect to multiple meters at the same time, and one meter is allowed to connect to multiple metering areas at the same time. In the latter case, the meter can set the allocation parameters. If not set, the default is equal allocation.

[0008] Regarding meters and their sub-meters, the meter's metering range is the sum of the lowest level of the area it's connected to (generally, all rooms). A single meter can, in principle, have an unlimited number of sub-meters, but each sub-meter's metering range must fall within the parent meter's. Regarding central air conditioning power consumption calculations, a single master meter is typically used to record the unit's total power consumption. Each room's air outlet is managed by its own timed valve. Therefore, timed valves are not sub-meters, and the top-level meter for these timed valves must be the meter connected to the central air conditioner.

[0009] After determining the implementation framework of the present invention, the following is the technical solution for implementing this algorithm.

[0010] On the one hand, the present invention provides a method for calculating the meter-based allocation of basic energy consumption such as electricity, water, and gas. Here, the calculation of electricity consumption is used as an example to calculate the energy consumption allocation of hospital departments.

[0011] To calculate the energy consumption of electricity meters in hospital departments: first, you need to obtain information about all rooms in the department, and then perform energy consumption statistics for each room.

[0012] Obtain all electricity meters, including sub-meters and sub-meters, whose metering range includes the requested room. Then, sort these meters by meter level, with no explicit restrictions for meters of the same level. Then, iterate through the sorted meters in order, calculating the energy consumption of each meter according to the following rules. (Meter readings in the following steps are all current values, i.e., the difference from the previous reading).

[0013] S1. First determine whether the table has a sub-table. If no sub-table exists, proceed to step S2; otherwise, proceed to step S4. S2. Obtain the metering range of the meter. If it only includes the requested room, the meter reading is the power consumption of the room. If the metering range includes other rooms in addition to the requested room, proceed to step S3. S3. Obtain the allocation ratio set for the meter. The power consumption of the room in question in the meter can be calculated based on the meter reading of the allocation ratio. S4. For all sub-tables, first determine whether the measurement range of these sub-tables includes the requested room. If the measurement range of at least one table includes the requested room, no further measurement is performed on that table and the value is recorded as zero. If none of the sub-tables include the requested room, proceed to step S5. S5. Obtain the area that differs between the metering range of the table and the metering ranges of all sub-tables. If the area contains only the requested room, proceed to step S6; if it contains more than the requested room, proceed to step S7. S6. Subtract the sum of the readings of all sub-meters from the reading of the meter, and the result is the energy consumption of the room; S7. Subtract the sum of the readings of all sub-meters from the reading of the meter and divide the result by the number of the different areas to make an average of the power consumption. The result is the power consumption of the room in the meter.

[0014] After the traversal is complete, the readings from each meter are added together to obtain the meter power consumption for that room. The power consumption of all rooms in the department is then calculated using the same method, and the total power consumption for the department is obtained.

[0015] Another aspect of the present invention provides a method for calculating the power consumption of central air conditioning in a department.

[0016] For other energy consumption types, such as water and gas, the metered consumption often represents the final energy consumption. However, in a hospital setting, it's often necessary to separately calculate the power consumption of central air conditioning. The following steps describe how to calculate the power consumption of central air conditioning in a department. Similarly, first obtain all rooms within the department and then calculate the power consumption of the central air conditioning in each room.

[0017] S1. First, obtain all time valves connected to the desired room, and then traverse these time valves in sequence; S2. Find the uppermost instrument of the time valve, which is the power supply connected to the central air conditioner; S3. Calculate all time valves of the central air conditioner and traverse each time valve; S4. Obtain the setting data of the time valve and the metering readings of each gear. Calculate the metering value according to the formula: high-speed time reading * high-speed parameter + mid-speed time reading * mid-speed parameter + low-speed time reading * low-speed parameter. Record the metering value of the time valve in question. S5. Add up the measurement values ​​of all time valves under the central air conditioner to obtain the total air output measurement value of the central air conditioner; S6. Divide the meter reading by (the measured value of the time valve to be determined / the total air volume of the central air conditioner). The result is the power consumption of the time valve. S7. After traversing all the time valves connected to the table, the power consumption obtained by each time valve is added up, and the result is the central air-conditioning power consumption of the desired room.

[0018] Add up the central air-conditioning power consumption of all rooms under the department to get the central air-conditioning power consumption of the department.

[0019] Compared with the existing energy consumption sharing method in hospitals, the technical effects brought by this invention are superior in the following three aspects:

[0020] 1. Effectively optimize the hospital's existing manual energy consumption management model of offline meter reading and manual calculation and allocation. Through a fully automated online process, manual errors are reduced. Only basic data entry is required at the initial stage, and only regular inspections and maintenance are required thereafter. This improves the efficiency of energy consumption performance management, making it convenient and efficient.

[0021] 2. A more scientific and comprehensive allocation calculation method. The content of this invention refers to the various energy consumption calculation allocation methods currently on the market.

[0022] 3. At the same time, the current status of many hospitals was examined, combined with various possible sharing scenarios.

[0023] 4. It can better assist hospitals in managing the energy consumption performance of departments, monitor hospital energy consumption, reduce energy consumption, reduce energy costs, and improve the hospital's economic benefits. Based on the calculated energy consumption allocation, the hospital can further expand the present invention to obtain advanced data such as hospital department energy consumption, hospital historical energy consumption, energy consumption change rate, daily and monthly year-on-year comparison, etc., to assist in the hospital's energy consumption monitoring.

This is to more clearly demonstrate the content and process of this algorithm. The following will also be described through a specific embodiment with reference to the information in the figure. DETAILED DESCRIPTION

[0028] In this hospital case, there are two departments: Internal Medicine and Emergency Department. There are two buildings under the hospital, each connected to a central air conditioner, and there are a total of eight rooms under each building, with ten electricity meters and six time valves. The specific meter connection conditions and meter readings are as follows: Figure 1 As shown, the specific energy consumption calculation implementation method will also be combined with Figure 2 and Figure 3 Provide explanation.

[0029] Example 1.

[0030] like Figure 2 , assuming that you want to calculate the electricity consumption of the internal medicine department, the steps are as follows.

[0031] First get all the rooms belonging to the internal medicine department, namely 111 and 211.

[0032] First calculate the electricity consumption of the electricity meter in room 111.

[0033] S1. Obtain all the electricity meters measuring room 111, and obtain meters A and A1. S2. Traverse tables A and A1 in table level order, traversing table A first; S3. Check whether table A has any child tables. S4, Table A has sub-tables: A1, A2, A3; S5. Determine whether these sub-tables of table A contain room 111; S6. If table A1 contains room 111, table A is not measured and the next table is traversed: table A1. S7. Check whether table A1 has any child tables. Tables S8 and A1 have no sub-tables and perform data calculations directly; S9. Get the allocation information of table A1, 111:112=1:2; S10, the power consumption is calculated as: 30*(1 / (1+2))=10; S11. All meters have been traversed, and the power consumption of the meter in room 111 is 0+10=10.

[0034] Then calculate the electricity consumption of the electric meter in room 221.

[0035] S1. Obtain all the electricity meters in room 221 and obtain meters B, B2, C, and C2. S2. Traverse tables B, B2, C, and C2 in table level order, starting with table B. S3. Check whether table B has any child tables. S4, Table B has sub-tables: B1, B2; S5. Determine whether these sub-tables of table B contain room 221; S6. Table B2 contains room 221, so table B is not measured. The next table is traversed: table C. S7. Check whether table C has any child tables. Table S8 and C have subtables C1 and C2; S9. Determine whether these sub-tables of table C contain room 221; S10, since table C2 contains room 221, table C is not measured, and the next table is traversed: table B2; S11. Check whether table B2 has any child tables. Tables S12 and B2 have no sub-tables and perform data calculations directly; S13. Obtain the allocation information of table B2, and find that table B2 has no allocation information; S14, power consumption is the meter reading: 30; S15. Continue to traverse the next table: C2 table; S16. Check whether table C2 has any child tables. Tables S17 and C2 have no sub-tables and perform data calculations directly; S18. Obtain the allocation information of Table C2, and find that Table C2 has no allocation information; S19, power consumption is the meter reading: 10; S20. All meters have been traversed, and the power consumption of the meter in room 221 is 30+10=40.

[0036] Finally, calculate the power consumption of the central air conditioner in room 111.

[0037] S1. Get the central air conditioner corresponding to room 111: central air conditioner 1; S2. Get all time valves of central air conditioner 1: 111, 112, 121; S3. Calculate the air volume of the 111 time valve: 20*5+15*3+5*1=145; S4. Calculate the air volume of the time valve 112: 15*5+10*3+30*1=135; S5. Calculate the air volume of the 121 time valve: 10*5+25*3+20*1=145; S6. Get the electric meter reading of central air conditioner 1: 100; S7. Calculate that the power consumption of the central air conditioner in room 111 is approximately: 100*(145 / (145+135+145))=34.12.

[0038] Add up the readings of the three calculations to get the total power consumption of the internal medicine department: 10+40+34.12=84.12.

[0039] Example 2.

[0040] like Figure 3 , assuming that you want to calculate the electricity consumption of the emergency department, the steps are as follows.

[0041] First, get the rooms belonging to the emergency department, namely room 222 and room 122.

[0042] First calculate the power consumption of room 222.

[0043] S1. Get all the electricity meters in room 222 and get meter B. S2. Check whether table B has any child tables. S3, Table B has sub-tables: B1, B2; S4. Determine whether these sub-tables of table B contain room 222; S5. All sub-tables of table B do not contain room 222. The power consumption of room 222 needs to be summed up by the difference method. Metering rooms for S6 and B meters include 211, 221, and 222. Metering rooms for B1 and B2 include 211 and 221; S7, the difference in room value is 222, and the difference in meter data is 80-(20+30)=30; S8. The electricity consumption of room 222 is: 30 / 1=30.

[0044] Then calculate the electricity consumption of the electric meter in room 122.

[0045] S1. First, obtain all the electricity meters connected to room 122: A, A2, and A3. S2. Traverse table A first according to the order of table levels; S3. Determine whether table A has a subtable; S4, yes, get all sub-tables A1, A2, A3 of table A; Room 122 is included in S5, sub-tables A2, and A3, so it is not measured; S6. Check whether table A2 has a sub-table. No sub-table exists. S7. Obtain the apportionment ratio 3 / 4 of Table A2; The electricity consumption shared by room 122 in the meter readings of S8 and A2 is 40*3 / 4=30; S9. Check whether table A3 has any child tables. No child tables exist. S10, and A3 meter has no apportionment, so the power consumption is the meter reading, which is 30.

[0046] Finally, calculate the power consumption of the central air conditioner in room 222.

[0047] S1. Get the central air conditioner corresponding to room 222: central air conditioner 2; S2. Get all time valves under central air conditioner 2: 211, 222, 231; S3. Calculate the air volume of the 211 time valve: 15*5+30*3+5*1=170; S4. Calculate the air volume of the 222 time valve: 20*5+10*3+20*1=150; S5. Calculate the air volume of the 231 time valve: 5*5+15*3+30*1=100; S6. Get the electric meter reading of central air conditioner 1: 200; S7. Calculate that the power consumption of the central air conditioner in room 111 is approximately: 200*(150 / (170+150+100))=71.43.

[0048] Add the three calculated readings to get the total electricity consumption of the emergency department: 30 + 30 + 71.43 = 131.43.

[0049] The above are two hypothetical implementation examples, respectively calculating the room's electricity meter consumption and the central air conditioning power consumption data. For the calculation of water and gas meter data, you can refer to the electricity meter power consumption.
