Abstract
Description
[Technical field]
[0001] The present invention relates to a support system for the deployment of compatible batteries for hospital beds. [Background technology]
[0002] In order to maintain a continuous supply of power, data centers, factories such as semiconductor manufacturing plants, hospitals, and the like often have uninterruptible power supply equipment and private power generation equipment in preparation for power outages in the grid.
[0003] For example, Patent Document 1 discloses a system equipped with multiple regular UPS (Uninterruptible Power Supplies) and a spare UPS that commonly backs up the regular UPS. Patent Document 2 discloses a technology for extending the operating time of a UPS by controlling the power supply status of medical equipment in an operating room that receives power from the UPS.

[0004] [Patent Document 1] JP 2018-11487 A [Patent Document 2] JP 2020-162320 A Summary of the Invention [Problem to be solved by the invention]
[0005] Conventional technologies were large-scale, with emergency power supply equipment such as uninterruptible power supply equipment and private power generation equipment being concentrated in specific locations of facilities or buildings, such as specific rooms or specific floors. In addition, most of the conventional technologies were based on the assumption that emergency power supply equipment exists, and were concerned with how to use the emergency power supply equipment in an emergency. In addition, in data centers, factories, etc., the power demand does not fluctuate greatly in order to ensure stable operation, and the power demand can be determined in advance. Above all, in facilities such as data centers and factories, the power demand can be controlled at the operator's discretion. Therefore, it was relatively easy to design emergency power supply equipment in advance before the construction or operation of the facility. However, in hospitals, the bed usage situation changes depending on epidemics and changes in the local medical system, and the equipment required changes depending on each hospitalized patient, so the circumstances of power demand are completely different from those of data centers, factories, etc. Furthermore, attempting to meet the maximum temporary power demand that may be required for the entire hospital would require the deployment of large-scale emergency power equipment in a specific location, which would require the deployment of excessively large-capacity power equipment and the preparation of corresponding power distribution facilities, and this was often not cost-effective from the perspective of hospital management.
[0006] The problem to be solved by the present invention is to provide a technique for supporting the introduction of emergency power supply equipment for hospital beds. [Means for solving the problem]
[0007] The first invention for solving the above-mentioned problems is a hospital bed compatible battery deployment support system including a power relay device that relays and outputs externally supplied power and a computer system, The power relay device includes a measurement unit that measures any one of a voltage, a current, and a power to be relayed, a storage unit, a communication unit, and a control unit; The control unit, in a monitoring state in which the control unit is connected so as to be interposed between a power supply facility in a hospital room and an electrical facility in a hospital bed and / or an electrical device used by an inpatient in the hospital bed (collectively referred to as "hospital bed individual equipment" below), performs control to cumulatively store monitoring data in the storage unit, the monitoring data being associated with measurement results by the measurement unit and measurement dates and times, and control to transmit the monitoring data to the computer system; When a battery is installed in a power line from a power supply facility in a hospital room to an individual device in the hospital bed and charging and discharging of the battery are controlled, the computer system calculates a control logic for charge and discharge control and a battery specification that satisfies a given low-cost condition for electricity charges based on the monitoring data and a given time-of-day electricity charge.

[0022] According to the eighth aspect of the present invention, a battery deployment plan can be calculated that takes into account the increase or decrease in the power demand of individual hospital bed equipment.
[0023] A ninth invention is the above-mentioned hospital bed compatible battery deployment support system, wherein the computer system recalculates the battery deployment plan at a given timing.
[0024] According to the ninth aspect of the present invention, after a battery deployment plan proposal is calculated once, the battery deployment plan proposal can be recalculated at a given timing.

[0032] 1 is a diagram showing an example of a hospital having hospital beds. The hospital 10 has one or more patient rooms 12, and each patient room 12 has one or more patient beds 20.
[0033] FIG. 2 is a diagram showing an example of a hospital bed. The hospital bed 20 has a bed body 21 and individual hospital bed equipment 22. The bed-specific equipment 22 includes electrical equipment 24 for the bed and electrical equipment 26 used by the hospitalized patient in the bed. Depending on the expected condition of the hospitalized patient, the bed-specific equipment 22 may include only one of the electrical equipment 24 and the electrical equipment 26.
[0034] The electrical equipment 24 of the hospital bed includes, for example, an electrically operated movable part of the bed body 21, accessories of the bed body 21, a heater or cooler for adjusting the temperature of the bed body 21, a hand lamp, and a foot lamp. Examples of movable parts of the bed body 21 include a bottom, a frame, a handrail, a table, a traveling device, etc. Examples of accessories of the bed body 21 include a liftable table that is attached to the bed body 21, and an electric arm that can electrically change the holding position of a monitor, a tablet computer, etc.
[0035] The electrical equipment 26 used by the hospitalized patient in the hospital bed includes one or more medical equipment 27 and non-medical equipment 28 (eg, TV, refrigerator) that are configured in various ways depending on the condition of the hospitalized patient in the hospital bed.
[0036] The medical device 27 is, for example, an infusion pump, a syringe pump, a bedside monitor (a composite device also called a patient monitor or a vital sign monitor), an oxygen inhaler, a foot pump, an air mat, an artificial respirator, etc. Of course, more advanced devices than these may also be included.
[0037] The number and configuration of the individual bed equipment 22 in one hospital bed 20 varies depending on the condition of the hospitalized patient in the hospital bed, and increases or decreases from the initial configuration depending on the change in the condition of the hospitalized patient. In addition, the configuration of the individual bed equipment 22 may be changed depending on the hospital room.
[0038] The hospital beds 20 are divided into a number of bed types depending on the configuration of the electrical equipment 24 and the electrical devices 26. The method of division can be set appropriately according to the condition of the admitted patients. In the following, the explanation will be given by dividing into first type, second type, and third type beds.
[0039] Type 1 beds are intended for hospitalized patients who are seriously ill or who are at risk of becoming seriously ill and require follow-up observation. Type 2 beds are intended for hospitalized patients whose condition has stabilized but who still have a risk of worsening. Type 3 beds are intended for hospitalized patients whose condition has stabilized to a certain extent. Focusing on the power consumed by one hospital bed 20, Type 1, Type 2, and Type 3 beds have high, medium, and low power consumption, respectively.
[0040] The number of hospital beds 20 in one hospital room 12 and the type of hospital beds 20 in one hospital room 12 can be set appropriately.
[0041] FIG. 3 is a diagram for explaining a configuration example of a hospital bed compatible battery deployment support system 50 and the purpose of the system. The hospital bed compatible battery deployment support system 50 comprises a power relay device 60 that relays externally supplied power and outputs it to the hospital bed individual equipment 22, and a computer system 80 that is connected to and communicates with the power relay device 60.
[0042] The hospital bed compatible battery deployment support system 50 monitors the power consumption of the hospital bed individual equipment 22 using a power relay device 60 provided for each of the multiple hospital beds 20. Then, based on the monitoring data and the like, a computer system 80 creates a battery deployment plan proposal for deploying batteries 52 in the power lines 17 from the power supply equipment 16 (e.g., a power outlet provided on a wall) of the hospital room 12 to the hospital bed individual equipment 22. The management of the hospital 10, which is the user of the hospital bed compatible battery deployment support system 50, can plan battery deployment by referring to the battery deployment plan proposal created by the hospital bed compatible battery deployment support system 50.
[0043] Although FIG. 3 shows an example in which one hospital bed 20 is assigned to one battery 52, a plurality of hospital beds 20 may be assigned to one battery 52 (described in detail later).
[0044] The battery 52 has a UPS function and a schedule function that can set a timer for charging and discharging periods. The battery 52 uses the schedule function to charge from the grid power during the charging period and relay and supply the grid power to the individual hospital bed equipment 22. During the discharging period, the relay supply of the grid power is cut off while the stored electricity is supplied. However, if the amount of electricity stored in the battery 52 reaches a predetermined reduction threshold due to the supply of stored power during the discharging period, the relay supply of the grid power is resumed and charging is suppressed. Note that if the battery 52 is fully charged, float charging may be performed outside the charging period.
[0045] FIG. 4 is a diagram for explaining a configuration example of the power relay device 60. As shown in FIG. The power relay device 60 has a plug 61 to be inserted into the power supply equipment 16 (e.g., a power outlet installed on a wall) of the hospital room 12, a plug socket 62 for inserting the power plug of the hospital bed individual equipment 22, and a case 63.
[0046] A measuring unit 65 is provided in the relay line 64 connecting the plug 61 and the plug socket 62 to measure any one of the voltage, current, and power to be relayed. In the example of Fig. 4, a voltmeter 65a and an ammeter 65b are illustrated as the measuring unit 65, but a power meter may be added or may be replaced by one power meter. The measuring unit 65 measures the power consumption. Then, the measuring unit 65 outputs an electric signal indicating the measurement result to the control unit 70 built in the case 63.
[0047] The control unit 70 includes a CPU 71 , a storage unit 72 , and a communication unit 74 . The storage unit 72 is realized by, for example, an IC memory, and stores programs and various data. The communication unit 74 is realized by, for example, a wireless communication device, and executes predetermined communication with the computer system 80 and other power relay devices 60 via wireless communication.
[0048] The CPU 71 executes a predetermined program stored in the storage unit 72 to perform monitoring control and data transmission control.
[0049] Through monitoring control, monitoring data 75 is cumulatively stored in the memory unit 72. The monitoring data 75 is data in which the measurement results by the measurement unit 65 are associated with the measurement date and time in a monitoring state in which the power relay device 60 is connected so as to be interposed between the power supply equipment 16 of the hospital room 12 and the hospital bed individual device 22. Specifically, a data set in which a device ID for individually identifying the power relay device 60, a measurement date and time, and a power consumption value (or a voltage value and a current value) are associated with each other is cumulatively stored in chronological order. The monitoring period and the number of data sets can be set appropriately.
[0050] The power relay device 60 transmits the monitoring data 75 to the computer system 80 at a predetermined period by data transmission control.
[0051] The wireless communication standard adopted by the communication unit 74 can be appropriately set. In case direct communication from the power relay device 60 to the computer system 80 is not possible, the communication unit 74 supports multi-hop communication and can transmit the monitoring data 75 to the computer system 80 via another power relay device 60.
[0052] FIG. 5 is a diagram for explaining an example of the configuration of a computer system 80. As shown in FIG. The computer system 80 is realized by, for example, a personal computer, etc. The computer system 80 is installed in a location within a range where it can be wirelessly connected to the power relay device 60 directly or via multi-hop communication.
[0053] The computer system 80 has a monitor 82, an operation input unit 84, and a control unit 90. The operation input unit 84 is a device for a user of the hospital bed compatible battery deployment support system 50 to input various setting data, and is realized by a keyboard, a touch panel, or the like.
[0054] The control unit 90 includes a CPU 91, a storage unit 92, and a communication unit 94. The storage unit 92 is realized by, for example, an IC memory, a hard disk, online storage, etc. The communication unit 94 supports the same wireless communication standard as the communication unit 74 of the power relay device 60.
[0055] The storage unit 92 stores a support program 100, bed-specific monitoring data 110, hospital room registration data 120, time-of-day power fee setting data 130, and expected power outage duration setting data 140. It also stores candidate battery group data 150, allowable fee setting data 170, the number of permitted battery sharing 172, battery deployment plan proposal data 200, and the current date and time 900.
[0056] The computer system 80 realizes a function of calculating a battery deployment plan and presenting it to the user by causing the CPU 91 to perform calculations on an assistance program 100 stored in the storage unit 92 .
[0057] As basic data for calculating the battery deployment plan, the computer system 80 receives monitoring data 75 from the power relay device 60 and stores the received monitoring data 75 as bed-specific monitoring data 110.
[0058] As shown in FIG. 6, each bed-specific monitoring data 110 includes a power relay device ID 112 indicating the power relay device 60 that sent the original monitoring data 75, and time-series power consumption data 114 that stores the measurement date and time and the power consumption value in chronological order.
[0059] The power consumption value for each measurement date and time is added based on the monitoring data 75 received one after another, and the data is accumulated and recorded in the time-series power consumption data 114. By referring to the time-series power consumption data 114, the usage status of the hospital bed 20 at each measurement date and time can be known. For example, if the power consumption value is less than a predetermined standby power reference value, it is known that the individual hospital bed equipment 22 is not being used and the hospital bed 20 is an "empty hospital bed". By dividing the power consumption of each hospital bed 20 by bed type and performing statistical processing, it is possible to know the standard power consumption for each bed type. If the power consumption temporarily increases above the standard power consumption, it can be known that the condition of the hospitalized patient in the hospital bed 20 has deteriorated and a medical device 27 has been added. If the power consumption returns to the standard power consumption, it can be inferred that the condition has improved to the point where the added medical device 27 is no longer used.
[0060] Returning to Figure 5, the hospital room registration data 120, time-of-day electricity fee setting data 130, expected power outage duration setting data 140, candidate battery group data 150, allowable fee setting data 170, and permitted number of shared batteries 172 are set and stored based on operational inputs by the user of the hospital bed compatible battery deployment support system 50.
[0061] The hospital room registration data 120 is prepared for each hospital room 12, and stores information about the hospital beds 20 arranged in the hospital room. For example, as shown in Fig. 7, one hospital room registration data 120 stores a hospital room ID 121 and one or more hospital bed registration data 122. One hospital bed registration data 122 stores a hospital bed ID 123, a hospital bed type 124, and a power relay device ID 125 that indicates the power relay device 60 connected to the power line of the hospital bed individual device 22 of the hospital bed.
[0062] Returning to Fig. 5, the time-of-day electricity rate setting data 130 is data on electricity rates for each time period provided by a power grid company that is expected to be used by the user of the hospital bed compatible battery deployment support system 50. Specifically, it includes a low-cost condition satisfying time period 132 indicating a time period during which electricity rates are recognized as low for the user of the hospital bed compatible battery deployment support system 50, a low-cost condition satisfying rate 134 which is the electricity rate for that time period, a high price time period 136, and a high price rate 138 which is the electricity rate for that time period.
[0063] The user of the hospital bed compatible battery deployment support system 50 sets the contents of the time-of-day electricity rate setting data 130 using the operation input unit 84, thereby setting the low-cost conditions related to the electricity rate that must be satisfied in order to calculate the battery deployment plan. Therefore, it can be said that the control unit 90 functions as a setting unit 95 that sets the low-cost conditions.
[0064] The expected power outage duration setting data 140 is basic data for determining the capacity specifications required for the battery 52 (see FIG. 3) as a UPS. It stores the desired duration (operating duration) for continuing power supply after a power outage in the grid. The duration may be "0".
[0065] The candidate battery group data 150 is a data group regarding candidates for the battery 52. For example, as shown in Fig. 8, the candidate battery group data 150 includes candidate battery data 151 for each specification of the candidate battery.
[0066] Each candidate battery data 151 includes a battery specification ID 152 , a manufacturer name 153 , a model number 154 , a battery price by specification 155 equivalent to the purchase price of the battery, a life cycle cost 156 , and specification data 160 .
[0067] The specification data 160 includes, for example, a battery capacity 161, a charger output 162, a guaranteed charging cycle count 163, a guaranteed year count 164, and a guaranteed capacity 165. Of course, data other than these may be included as appropriate.
[0068] 5, the allowable fee setting data 170 is an amount that is allowable by a user of the hospital bed compatible battery deployment support system 50 as the total fee for the deployed battery 52 when deploying the battery 52. In other words, it is a budget amount.
[0069] The permitted number of battery sharing 172 is the maximum number of hospital beds 20 that a user of the hospital bed compatible battery deployment support system 50 is permitted to share one battery with.
[0070] FIG. 9 is a diagram for explaining the formulation of a battery deployment plan by the hospital bed compatible battery deployment support system 50. As shown in FIG. In the example of FIG. 9, a hospital 10 has two hospital rooms 12 (hospital room A and hospital room B), each of which has multiple hospital beds 20. "Hospital room A" has six hospital beds 20, "A01" to "A06". "Hospital room B" has six hospital beds 20, "B01" to "B06". Electric power is supplied to the individual hospital bed devices 22 of each hospital bed 20 via a power relay device 60, and the power consumption of each is monitored by the power relay device 60.
[0071] The hospital bed compatible battery deployment support system 50 selects a battery 52 (compatible battery) that is compatible with the usage conditions estimated from the results of monitoring the power consumption of the individual hospital bed devices 22 of each hospital bed 20 and that is compatible with the low electricity rate conditions desired by the user from among the candidate batteries set in the candidate battery group data 150. Then, the control logic for the charge and discharge control is calculated. This becomes the battery deployment plan proposal.
[0072] In the battery deployment plan proposal, one connection group ("G01" to "G05" in the example of FIG. 9) is created with one or more hospital beds 20, and one battery 52 suitable for the connection group is selected and assigned. However, a connection group is not formed across hospital rooms 12. In other words, the computer system 80 calculates the battery deployment plan proposal based on a prohibition condition that prohibits the application of the option of deploying one battery 52 to beds 20 in different hospital rooms 12 (i.e., to "two" or more hospital beds 20).
[0073] FIG. 10 is a diagram showing an example of the data configuration of the battery deployment plan data 200. As shown in FIG. The battery deployment plan data 200 includes a plan ID 201, a creation date and time 202, control logic data 205, a bed arrangement plan data 210, a total battery charge 230, spare battery plan data 232, and power demand data at the time of creation 234. Of course, data other than these may also be included as appropriate.
[0074] The control logic data 205 indicates a control logic for charge / discharge control such that the power fee satisfies a given low-cost condition. Specifically, information on one or more charging time periods and one or more discharging time periods in a day is stored. When the battery deployment plan proposal data 200 is adopted, the user of the hospital bed compatible battery deployment support system 50 sets the schedule function of each battery 52 according to the control logic data 205 of the battery deployment plan proposal data 200.
[0075] The control logic data 205 is determined based on the time-of-day power rate setting data 130 (see FIG. 5). Specifically, the low-cost condition fulfilling time period 132 is set as the charging time period, and the high-price time period 136 is set as the discharging time period. If the high-price time period 136 is not set, a predetermined initial setting time period is set as the discharging time period.
[0076] The bed layout plan proposal data 210 indicates the layout of hospital beds in the battery deployment plan proposal data 200, that is, the number of hospital beds 20 of each bed type to be arranged in each hospital room 12. Specifically, the bed layout plan proposal data 210 has room-specific layout plan proposal data 212 for each hospital room 12 in the hospital room registration data 120 (see FIG. 7).
[0077] Each hospital room layout plan data 212 includes a hospital room ID 213 , a list of the number of hospital beds by bed type 214 , and battery allocation plan data 220 .
[0078] The battery allocation plan data 220 is created for each battery 52 installed in the hospital room, in other words, for each connection group of the individual hospital bed devices 22 connected to one battery 52. One battery allocation plan data 220 includes a compatible battery specification ID 221, a connection group ID 222, a type of hospital bed constituting the group 223, a number of hospital beds constituting the group 224, and an expected lifespan unit cost 225.
[0079] The compatible battery specification ID 221 indicates any one of the candidate batteries in the candidate battery group data 150 (see FIG. 8).
[0080] The group composition bed type 223 and the group composition bed number 224 indicate the composition of the connection group (see FIG. 9) connected to the battery 52. In other words, the group composition bed type 223 and the group composition bed number 224 indicate which bed type and how many bed individual devices 22 of beds 20 the battery 52 is connected to and supplies power to.
[0081] The expected lifespan unit price 225 is a unit price per day on the assumption that the battery 52 indicated by the compatible battery specification ID 221 is used for the warranty period 164 in accordance with the battery deployment plan data 200 .
[0082] The spare battery plan data 232 stores the number of spare batteries in association with each battery specification ID of the spare battery. The spare batteries include a "basic spare" and an "additional spare".
[0083] The "basic reserve" is a reserve that assumes replacement in the event that the battery 52 fails. Specifically, the total number of batteries is calculated for each compatible battery specification ID 221 of all the battery allocation plan data 220, and the number of spare batteries for each compatible battery specification ID 221 is calculated using a predetermined function with the calculated total number as a variable. The predetermined function can be set appropriately taking into consideration the probability of battery 52 failure and the additional quantity ratio as an insurance measure in case of a prolonged power outage.
[0084] The "additional spare" is an additional quantity intended as insurance in consideration of an increase in power demand that occurs when some of the hospital beds set in the initially assumed hospital room registration data 120 (see FIG. 7) are replaced with medical equipment 27 due to changes in hospitalized patients or changes in their condition. It is also a spare for replacing or additionally connecting batteries 52 with compatible battery specification ID 221 on an ad-hoc basis. It is also a spare for additional deployment when it becomes necessary to split a connection group in order to deal with changes in hospitalized patients or changes in their condition.
[0085] To set the number of additional spare units, the power demand fluctuation range (difference between standard power consumption and peak power consumption value) in the bed-specific monitoring data 110 (see FIG. 6) is referenced. In a bed 20 where the power demand fluctuation range has reached a predetermined additional standard value, it can be presumed that an additional bed individual device 22 (particularly medical equipment 27) is required due to a change in the condition of an inpatient. Alternatively, in a bed 20 where the power demand fluctuation range has reached a predetermined additional standard value, it can be presumed that the bed type in reality has changed to a higher type than the bed type set in the hospital room registration data 120 (for example, from a type 2 bed to a type 3 bed, or from a type 2 bed to a type 1 bed) due to a change to a new inpatient with a worse condition.
[0086] Specifically, a search is made for hospital beds 20 whose power demand fluctuation range value exceeds a predetermined additional reference value. If the bed type of the searched hospital bed 20 is a second or third type hospital bed, data of "a hospital bed 20 of a bed type one rank higher and to which one battery 52 is assigned" is searched from the battery allocation plan data 220. Then, a battery with the compatible battery specification ID 221 is added as an additional spare.
[0087] If the bed type of the searched bed 20 is a Type 1 bed, data is searched for that "bed 20 is a Type 1 bed and one battery 52 is assigned to that bed 20", and a battery with the compatible battery specification ID 221 is added as an additional spare.
[0088] The power demand data at creation 234 stores various information calculated based on the bed-specific monitoring data 110 when calculating the battery deployment plan proposal data 200, that is, information on the premise for creating the battery deployment plan proposal data 200. Specifically, the power demand data at creation 234 stores the standard power consumption by bed type, the power demand fluctuation range by bed type, and the maximum power consumption by bed type.
[0089] FIG. 11 is a diagram for explaining the flow of processing executed by the computer system 80. As shown in FIG. The computer system 80 first executes a premise setting process (step S10).
[0090] Specifically, a predetermined input screen is displayed to accept setting inputs regarding the bed configuration of each hospital room 12, the time-of-day power fee setting desired by the user, and the expected power outage duration required for the battery 52 as a UPS. Also accepted are setting inputs regarding information by specification of the batteries 52 that are candidates for deployment, the budget amount for the batteries, and the number of hospital beds 20 that are permitted to be allocated to one battery 52. These input results are stored as hospital room registration data 120, time-of-day power fee setting data 130, expected power outage duration setting data 140, candidate battery group data 150, allowable fee setting data 170, and permitted number of shared batteries 172.
[0091] Next, the computer system 80 starts collecting the monitoring data 75 accumulated in each power relay device 60 (step S12). The contents of the monitoring data 75 received from the power relay device 60 are cumulatively stored as bed-specific monitoring data 110 each time the monitoring data 75 is received.
[0092] Next, the computer system 80 judges whether the necessary amount of monitoring data has been collected based on the amount of data (e.g., one week's worth, one month's worth) accumulated in the bed-specific monitoring data 110. If the necessary amount of monitoring data has been collected (YES in step S14), the computer system 80 judges whether there is an input to start creating a plan based on the collected monitoring data. If an operation input to start creating a plan by the user of the hospital bed compatible battery deployment support system 50 is detected (YES in step S16), the computer system 80 executes a plan creation process to create new battery deployment plan data 200 (step S18).
[0093] 12 to 14 are flowcharts for explaining the flow of the plan creation process. As shown in FIG. 12, in the plan creation process, the computer system 80 calculates a control logic and creates control logic data 205 (step S50).
[0094] Next, the computer system 80 obtains the "standard power consumption by hospital bed type", the "power demand fluctuation range by hospital bed type", and the "maximum power consumption by hospital bed type" (step S52). The "standard power consumption by hospital bed type" is determined by calculating the standard power consumption (for example, the median value of power consumption indicating standby power or more) of each hospital bed from the bed-specific monitoring data 110 for each hospital bed 20, and obtaining a statistical value of the standard power consumption by each hospital bed type. For example, the average value or the median value may be used as the statistical value.
[0095] The “range of increase / decrease in electricity demand by type of hospital bed” is determined by calculating the “range of increase / decrease in individual electricity demand” from the difference between the individual standard power consumption and the peak power consumption for each hospital bed 20 from the bed-specific monitoring data 110, and obtaining a statistical value of the range of increase / decrease in individual electricity demand by type of hospital bed. The "maximum power consumption by hospital bed type" is the sum of the standard power consumption by hospital bed type and the fluctuation range of power demand by hospital bed type.
[0096] Next, the computer system 80 creates "all combinations of connection groups" with the battery sharing permission number 172 previously set by the user as the maximum number of hospital beds 20 that constitute one connection group (step S54).
[0097] A connection group is formed by hospital beds 20 of the same bed type in the same hospital room 12, with the maximum number of battery sharing permissions being 172.
[0098] For example, assume that the battery sharing permission number 172 is set to "3" and that three first-class beds 20 are arranged in a certain hospital room 12. The combination of connection groups created for the hospital room is as follows: (1) A combination of three connected groups of 20 single beds each; (2) a combination of two connected groups of 20 beds and one connected group of 20 beds; (3) a combination of three connected groups of 20 beds each; Three types of files will be created: If a hospital room 12 has three beds 20 of type 1 beds and three beds 20 of type 2 beds, a total of nine combinations of connection groups will be created for that hospital room 12 by combining the three combinations of beds 20 of type 1 beds with the three combinations of beds 20 of type 2 beds.
[0099] "All combinations of connection groups" encompasses all combinations of connection groups of each patient room 12 thus created. If the battery sharing permission number 172 is set to "3", all combinations created in this step will include (1) a combination in which all connection groups in all hospital rooms 12 are composed of one hospital bed 20. In other words, a combination in which one battery 52 is provided for one hospital bed 20 will be included.
[0100] Furthermore, all the combinations created in this step will include (2) a combination in which a connected group made up of one hospital bed 20 and a connected group made up of two hospital beds 20 are mixed. Furthermore, all the combinations created in this step include (3) a combination in which a connection group consisting of one hospital bed 20, a connection group consisting of two hospital beds 20, and a connection group consisting of three hospital beds 20 are mixed. That is, a combination in which one battery 52 is provided for multiple hospital beds 20 is included.
[0101] Each "combination of connected groups" included in the "all combinations of connected groups" becomes the basis for creating one bed arrangement plan data 210 (see FIG. 10).
[0102] Next, the computer system 80 executes a loop A for each combination of connection groups (steps S60 to S144; FIG. 14).
[0103] In loop A, the computer system 80 executes loop B for each connection group included in the combination of connection groups to be processed (steps S62 to S122; FIG. 13).
[0104] In loop B, the computer system 80 calculates the group total maximum power consumption of the connected group to be processed (step S64). Specifically, the computer system 80 multiplies the maximum power consumption by bed type calculated in step S52 by the number of hospital beds constituting the connected group to be processed.
[0105] Next, the computer system 80 multiplies the group total maximum power consumption [kW] by the duration [h] of the discharge time period set in the control logic data 205. Then, it calculates the control logic required capacity [kWh] required for charging and discharging by the control logic (step S66).
[0106] Next, the computer system 80 multiplies the group's total maximum power consumption [kW] by the time length [h] indicated by the expected power outage duration setting data 140 to calculate the power outage required capacity [kWh] required for the battery 52 to operate as a UPS (step S68).
[0107] Next, the computer system 80 multiplies the sum of the required capacity for control logic [kWh] and the required capacity for power outage [kWh] by a predetermined safety factor, and calculates the total required capacity [kWh] for the batteries 52 for the connection group to be processed in loop B (step S80).
[0108] Next, the computer system 80 makes a first selection by listing battery specification IDs 152 whose battery capacities 161 are equal to or greater than the total required capacity [kWh] from among the candidate batteries indicated by the candidate battery group data 150 (see FIG. 8) (step S82).
[0109] If there are no candidate batteries that qualify for the first selection (NO in step S84), the computer system 80 determines that the combination of connection groups to be processed in loop A is not feasible, discards it, and exits loop A (step S86).
[0110] If there is a candidate battery that meets the first selection criteria (YES in step S84), the process moves to FIG. 13, and the computer system 80 performs a second selection by listing battery specification IDs 152 from the candidate batteries that have a charger output 162 capable of charging the total required capacity [kWh] within the duration of the charging time slot of the control logic (step S90).
[0111] If there are no candidate batteries that qualify for the second selection (NO in step S92), the combination of connection groups to be processed in loop A is determined to be infeasible and is discarded, and loop A is exited (step S94).
[0112] If there is a candidate battery that is eligible for the second selection (YES in step S92), the computer system 80 executes loop C for each of the candidate batteries that have been selected for the second selection (steps S100 to S110).
[0113] In loop C, the computer system 80 first calculates the expected lifespan days [d] for the candidate battery to be processed, assuming that the battery is charged and discharged once a day at the group's total maximum power consumption [kWh] (step S102). Specifically, the guaranteed charging cycle number 163 (see FIG. 8) is multiplied by the battery capacity 161 [kWh] and a predetermined lifespan deterioration coefficient. The multiplied value is then divided by the group's total maximum power consumption [kWh], and then further divided by 24 [h].
[0114] Next, the computer system 80 calculates the life-time unit price [¥ / d] of the candidate battery to be processed (step S104). Specifically, the computer system 80 divides the life-cycle cost 156 by the expected life-time number of days [d].
[0115] Next, the computer system 80 calculates the cost reduction amount [Δ¥] per day when the user uses the time-of-day discount plan (step S106). Specifically, the difference [Δ¥] between the high price price 138 and the low price condition fulfillment price 134 is multiplied by the expected charging time [h] required to charge the control logic required capacity [kWh] with the candidate battery to be processed, and the result is divided by 24 [h].
[0116] Then, the computer system 80 subtracts the cost reduction amount per day [Δ￥ / d] from the cost per day of life [￥ / d] to calculate the expected cost per day of life 225 [￥ / d] (step S108), and exits loop C (step S110).
[0117] When loop C has been executed for all of the secondary selected candidate batteries, computer system 80 sets the candidate battery with the lowest (cheapest) expected life-day unit price 225 [￥ / d] among the secondary selected candidate batteries as the suitable battery for the connection group to be processed in loop B (step S120), and then exits loop B (step S122).
[0118] Turning now to FIG. 14, the computer system 80 calculates the total battery fee 230 by adding up the specification-specific battery fees 155 of all compatible batteries for the combination of connection groups being processed next in loop A (step S130).
[0119] Here, it is determined whether the calculated total battery charge 230 exceeds the battery budget indicated by the allowable charge setting data 170. If the budget is exceeded (NO in step S132), the computer system 80 determines that the combination of connection groups to be processed in loop A is not feasible, discards it, and exits loop A (step S134).
[0120] If the calculated total battery charge 230 is equal to or less than the battery budget amount (YES in step S132), the computer system 80 determines that the allowable charge condition is met, and next calculates the spare battery plan data 232 (step S140).
[0121] Specifically, the number of batteries to be deployed is listed by specification for the combination of connected groups that are the subject of processing in loop A, and the basic reserve for each specification is determined using a specified function based on the number of batteries to be deployed. The function ensures the probability of failure and the number of batteries to act as an insurance in case the power outage lasts longer than expected.
[0122] Also, a hospital bed 20 whose power demand fluctuation range value exceeds a predetermined additional reference value is searched for. If the bed type of the searched hospital bed 20 is a type 2 or type 3 hospital bed, data on "a hospital bed 20 of a bed type one rank higher and to which one battery 52 is assigned" is searched for from the battery allocation plan data 220. Then, a battery with the compatible battery specification ID 221 is added as an additional spare battery.
[0123] In addition, if the bed type of the searched hospital bed 20 is a Type 1 bed, data is searched for that "bed 20 is a Type 1 bed and one battery 52 is assigned to that bed 20", and a battery with the compatible battery specification ID 221 is added as an additional spare.
[0124] Next, the computer system 80 creates and stores new battery deployment plan proposal data 200 using the control logic data 205 obtained in step S50 and various data calculated in relation to loop A (step S142), and exits loop A (step S144).
[0125] When loop A has been executed for all combinations of connection groups, the computer system 80 ends the planning process.
[0126] Returning to Fig. 11, the computer system 80 presents the newly created battery deployment plan proposals to the user and accepts the user's selection operation of which plan proposal to adopt (step S150). When presenting the plans, a plan proposal in which all connection groups are composed of one hospital bed 20 is presented as "a first option of deploying one battery 52 for one hospital bed 20". For plans including connection groups composed of multiple hospital beds 20, a predetermined number of plans (e.g., the three plans with the lowest total battery fee 230) are presented in ascending order of the total battery fee 230 as "a second option of deploying one battery for two or more hospital beds".
[0127] Then, the selected plan is saved, and the data of the plan that was not selected is discarded (step S152).
[0128] Next, the computer system 80 determines whether a predetermined "re-creation condition" is satisfied (step S160). If the re-creation condition is satisfied (YES in step S160), the computer system 80 executes a premise setting acceptance process (step S162), executes a plan creation process, and recalculates a battery deployment plan (step S164).
[0129] The “re-creation condition” may be, for example, a predetermined time has elapsed since the creation date / time 202 of the currently adopted battery deployment plan. The re-creation condition may be when the premise of the proposed plan changes significantly. Specifically, the standard power consumption by type of hospital bed, the fluctuation range of power demand by type of hospital bed, and the maximum power consumption by type of hospital bed are calculated from the monitoring data by type of hospital bed 110 at a given timing (for example, once a week). Then, the information is compared with the power demand data at the time of creation 234, and when a difference that satisfies a predetermined demand change condition occurs, the re-creation condition can be set.
[0130] The re-creation condition may include a case where a user inputs a predetermined re-calculation execution operation. When the type of hospital room 12 assigned to the hospital room is changed or the number of hospitalized patients is increased or decreased, the hospital room registration data 120 that was the premise when the plan was created significantly deviates, so it is desirable for the user of the hospital bed compatible battery deployment support system 50 to input the re-calculation execution operation himself / herself, reset the hospital room registration data 120, and create a new plan.
[0131] After executing the plan creation process, the computer system 80 presents the newly created plan to the user and accepts a selection operation of the plan to be adopted (step S166).Then, the selected plan is saved as the newly adopted plan, and the battery deployment plan data 200 of the plan that has been adopted up until now is discarded (step S168).
[0132] As described above, according to this embodiment, it is possible to provide a technique for supporting the introduction of emergency power supply equipment for hospital beds.
[0133] That is, the hospital bed-compatible battery deployment support system 50 monitors the power consumption of each hospital bed 20 using the power relay device 60 and accumulates the monitoring data. Then, based on the monitoring data and the time-of-day electricity charges for externally supplied electricity, it calculates the battery specifications to be deployed and the control logic for controlling the charging and discharging of those batteries. In other words, it is possible to present the user of the hospital bed-compatible battery deployment support system 50 with battery specifications that are compatible with the power consumption status of the individual hospital bed devices 22 and the control logic for low-cost charging and discharging control.
[0134] [Modifications] Although examples of embodiments to which the present invention is applied have been described above, the forms to which the present invention can be applied are not limited to the above-described forms, and components can be added, omitted, or modified as appropriate.
[0135] (Variation 1) In the above embodiment, in step S54 of the plan creation process (see FIG. 12), when creating a connection group, the requirement that "a connection group is composed of beds 20 of the same bed type in the same hospital room 12" is applied, but this is not limited to this.
[0136] For example, a more relaxed requirement that omits "forming a connection group with beds 20 of the same bed type" may be applied, i.e., the requirement that "forming a connection group within the same hospital room 12" may be applied, allowing a configuration in which one battery 52 is shared by beds 20 of different bed types. Furthermore, the requirement itself may be omitted. However, when the requirement for creating a connection group is relaxed or omitted, when calculating the total maximum power consumption of the group in step S64, the maximum power consumption of each of the beds 20 that constitute the connection group is calculated by adding together the maximum power consumption of each of the beds 20 that constitute the connection group, rather than the maximum power consumption by bed type.
[0137] In the premise setting reception process in step S10, it is preferable that the user of the hospital bed compatible battery deployment support system 50 be able to arbitrarily select which connection group creation requirement to apply, and whether to omit or not omit the connection group creation requirement.
[0138] (Variation 2) For example, the hospital bed compatible battery deployment support system 50 may be configured to calculate a battery deployment plan including a bed layout plan that is premised on changing the layout of the hospital beds 20 in each hospital room 12 to a layout different from that in the hospital room registration data 120. Specifically, following step S18 or step S164, a layout change premise plan creation process as shown in FIG.
[0139] In the process of creating a premise change plan proposal, the computer system 80 searches the bed-specific monitoring data 110 for beds 20 whose power consumption values have remained below a predetermined standby power standard value for a predetermined period of time or more, and extracts "vacant beds" and "vacant rooms" (step S200).
[0140] Next, when there are multiple "vacant rooms" (YES in step S202), the computer system 80 creates a bed layout plan for rearranging the beds 20 in one "vacant room" to fill the "vacant beds" in the other "vacant rooms" and saves it as "recommended bed registration data" (step S204). The recommended bed registration data has the same data structure as the hospital room registration data 120.
[0141] The arrangement of the hospital beds 20 may be changed by moving the bed body 21 and its individual hospital bed equipment 22 together with the hospitalized patient, or by moving the hospitalized patient and the individual hospital bed equipment 22 while leaving the bed body 21 in place. In other words, it is preferable that the hospital bed arrangement plan created in step S204 creates room allocation for hospitalized patients so as to reduce the number of "available hospital rooms" with "vacant hospital beds" as much as possible.
[0142] Then, the computer system 80 executes a plan creation process based on the bed allocation plan (recommended bed registration data) created in step S204 (step S206).
[0143] By adding the bed layout plan creation process, when a plan is presented to the user, a battery deployment plan based on the hospital room registration data 120 set by the user and a battery deployment plan based on the hospital bed layout plan are presented, further enhancing the effectiveness of support for users of the hospital bed compatible battery deployment support system 50 in creating plans.
