(Embodiment)
[Constitution]
A maintenance contract cost calculation system according to an embodiment will be described below. FIG. 1 is a block diagram showing the functional configuration of the maintenance contract cost calculation system according to the embodiment.

The maintenance contract cost calculation system 10 is a system for calculating a maintenance contract cost when a business operator A (or a general user) who owns the equipment 21 signs a maintenance contract with a business operator B who provides maintenance services for the equipment. . In general, the maintenance contract fee is empirically determined according to the number of years the equipment has been used, the scope of maintenance (items subject to maintenance), and the like. In this way, when maintenance contract costs are determined based on experience, business operator A pays the maintenance contract costs at the time of contract regardless of the occurrence of failures, repairs, or parts replacement, resulting in excessive maintenance contract costs. there is a possibility. In addition, if there are many failures, repairs, or part replacements, the operator B may not be able to cover the expenses with the already paid maintenance contract expenses.

On the other hand, in the maintenance contract cost calculation system 10, the maintenance contract cost is determined according to the environment in which the equipment 21 is used. The usage environment of the equipment 21 specifically includes temperature environment, humidity environment, power supply environment, and the like. When the equipment 21 is used in a severe environment, the probability of occurrence of failures of the equipment 21 increases, and the need for maintenance increases. In such a case, the maintenance contract cost calculation system 10 increases the maintenance contract cost. On the other hand, when the equipment 21 is used in an appropriate environment, the probability of failure of the equipment 21 or the like decreases, and the need for maintenance also decreases. In such a case, the maintenance contract cost calculation system 10 reduces the maintenance contract cost. According to the maintenance contract cost calculation system 10, both the business operator A and the business operator B can conclude a maintenance contract with an appropriate amount of money.

As shown in FIG. 1, the maintenance contract cost calculation system 10 includes a facility 21, a temperature sensor 22, a humidity sensor 23, a vibration sensor 24, a noise sensor 25, a power supply 26, and a first information terminal 27. , a second information terminal 30 , a server device 40 , and a weather information providing server 50 .

The facility 21 is a facility to be maintained, specifically an air conditioning facility. Equipment 21 may be equipment other than air conditioning equipment, and may be lighting equipment, elevators, escalators, ventilation equipment, motors, or the like. The facility 21 may be an industrial (business) facility or a residential facility. The equipment 21 may be equipment already purchased by the business operator A, or may be equipment lent (leased) from the business operator B or the like.

The temperature sensor 22 measures the temperature around the facility 21 or the temperature of the facility 21 itself, and transmits the measured temperature value to the first information terminal 27 . The temperature sensor 22 is implemented by, for example, a thermistor, a thermocouple, or a temperature measurement element such as an infrared detection element.

The humidity sensor 23 measures the humidity around the equipment 21 or the humidity inside the equipment 21 and transmits the measured value of the humidity to the first information terminal 27 . The humidity sensor 23 is realized by, for example, a humidity measuring element such as a capacitance type humidity sensing element or a resistance change type humidity sensing element.

The vibration sensor 24 measures the vibration at the installation location of the equipment 21 or the vibration of the equipment 21 itself, and transmits the measured value of the vibration to the first information terminal 27 . Vibration sensor 24 is implemented by, for example, an acceleration sensor, a piezoelectric sensor, or an ultrasonic sensor.

The noise sensor 25 measures the noise level around the facility 21 or the noise level of the sound emitted by the facility 21 itself, and transmits the measured value of the noise level to the first information terminal 27 . The noise sensor 25 is realized by a microphone or the like.

The power supply device 26 is, for example, a stabilized power supply device that supplies power to the facility 21 . In the maintenance contract cost calculation system 10, the power supply device 26 functions as a sensor that measures the voltage and current supplied to the equipment 21, and measures at least the voltage measurement value, the current measurement value, and the power consumption measurement value. One is transmitted to the first information terminal 27 .

Note that the maintenance contract cost calculation system 10 may not include the power supply device 26 when the facility 21 operates using power supplied from the power system. In such a case, the maintenance contract cost calculation system 10 includes a current sensor that measures the current supplied to the equipment 21 and a voltage sensor that measures the voltage supplied to the equipment 21 . The current sensor and voltage sensor in this case are separate from the equipment 21 , but may be incorporated in the equipment 21 . A power meter such as a smart meter may be used as the current sensor and the voltage sensor.

The first information terminal 27 receives the measured values output by the temperature sensor 22, the humidity sensor 23, the vibration sensor 24, the noise sensor 25, and the power supply device 26 through the local communication network, and transmits the received measured values to the server. It is a computer that sends to device 40 . The first information terminal 27 is specifically a general-purpose computer, but may be a dedicated computer for the maintenance contract cost calculation system 10 . Also, the first information terminal 27 may have a function as a controller that controls the facility 21 .

The second information terminal 30 is a computer for inputting information necessary for an employee b belonging to a business operator B to calculate a maintenance contract fee. The input information (hereinafter also referred to as input information) is transmitted to the server device 40 . The second information terminal 30 is, for example, a portable information terminal such as a tablet terminal or a smart phone, but may be a stationary information terminal such as a personal computer. The second information terminal 30 includes an input reception section 31 and a display section 32 .

The input reception unit 31 receives input of information such as employee b. The input reception unit 31 is realized by, for example, a touch panel, but may be realized by a mouse and a keyboard.

The display unit 32 displays the maintenance contract fee calculated by the server device 40 . The display unit 32 is realized by a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel. For example, employee b shows the maintenance contract fee displayed on the display unit 32 to user a who belongs to business operator A, and proposes a maintenance contract to user a. We will try to conclude a maintenance contract for

The server device 40 performs maintenance contract cost calculation processing based on the measurement values of various sensors transmitted by the first information terminal 27 and the input information transmitted by the second information terminal 30 . The server device 40 also performs display processing for displaying the calculated maintenance contract cost on the display unit 32 of the second information terminal 30 . The server device 40 is used by the operator B, for example, but may also be used by an operator C different from the operator A and the operator B. That is, the service of calculating maintenance contract costs may be provided by a third-party operator C. The server device 40 includes a communication section 41 , an information processing section 42 and a storage section 43 .

The communication unit 41 is a communication circuit (in other words, a communication module) for the server device 40 to communicate with the first information terminal 27, the second information terminal 30, and the weather information providing server 50 through the wide area communication network 60. . The communication performed by the communication unit 41 may be wireless communication or wired communication. The communication standard of communication performed by the communication unit 41 is not particularly limited either.

The communication unit 41 receives, for example, measurement values of various sensors transmitted by the first information terminal 27 and input information transmitted by the second information terminal 30 through the wide area communication network 60 . The communication unit 41 also transmits a display command to the second information terminal 30 via the wide area communication network 60 to display the calculated maintenance contract cost on the display unit 32 of the second information terminal 30 .

The information processing unit 42 performs the above-described maintenance contract fee calculation processing and display processing. The information processing unit 42 also performs information processing for displaying the calculated maintenance contract cost on the display unit 32 of the second information terminal 30 . The information processing unit 42 is specifically implemented by a microcomputer or processor.

The information processing section 42 has, as functional components, an acquisition section 42a, an assessment section 42b, a calculation section 42c, and a display processing section 42d. The functions of the acquisition unit 42a, the assessment unit 42b, the calculation unit 42c, and the display processing unit 42d are obtained by, for example, executing a computer program stored in the storage unit 43 by a microcomputer or processor constituting the information processing unit 42.

The weather information providing server 50 provides weather information to the server device 40 . The weather information includes temperature information and the like.

[Example of operation]
Next, an operation example of the maintenance contract cost calculation system 10 will be described. FIG. 2 is a sequence diagram of an operation example of the maintenance contract cost calculation system 10. As shown in FIG. In the following operation example, based on the measurement values of various sensors acquired in the most recent year (also described as the target period), the cost of the maintenance contract for the next year (also described as the contract period) An example of calculating is shown. Note that the target period and the contract period may be set in any way.

The first information terminal 27 transmits the measurement values of various sensors during the target period to the server device 40 (S11). The measured value may be periodically transmitted from the first information terminal 27 or may be transmitted in response to a request from the server device 40 .

The communication unit 41 of the server device 40 receives the measured values. The information processing section 42 stores the received measurement value in the storage section 43 (S12). At this time, the information processing unit 42 associates the contract ID issued to the business operator A when the maintenance contract of the previous year was concluded with the measurement value and stores it in the storage unit 43 .

After that, the employee b who belongs to the business operator B inputs information to the second information terminal 30 for calculating the maintenance contract cost (estimated amount) for the next one year. FIG. 3 is a diagram showing an example of an information input screen displayed on the display unit 32 of the second information terminal 30. As shown in FIG. As shown in FIG. 3, the employee b, for example, inputs the contract ID of the business operator A and the maintenance range (contract content) desired by the business operator A as contract information. The maintenance range input screen is, in other words, a maintenance menu selection screen.

The input receiving unit 31 of the second information terminal 30 receives input of contract information (S13), and the second information terminal 30 transmits the input contract information to the server device 40 (S14).

The communication unit 41 of the server device 40 receives the contract information. The calculation unit 42c performs maintenance contract cost calculation processing based on the measurement values of the various sensors stored in step S12 and the received contract information (S15). The details of the maintenance contract fee calculation process will be described later.

The display processing unit 42 d performs display processing for displaying the calculated maintenance contract cost on the second information terminal 30 . Specifically, the display processing unit 42d causes the communication unit 41 to transmit to the second information terminal 30 a display command for displaying the calculated maintenance contract fee on the second information terminal 30 (S16).

The second information terminal 30 receives the display command. Based on the received display command, the display screen of the maintenance contract fee is displayed on the display unit 32 (S17). FIG. 4 is a diagram showing an example of a maintenance contract fee display screen. Employee b (a person in charge of concluding a maintenance contract) shows a display screen such as that shown in FIG. A proposal can be made, and the conclusion of a maintenance contract between the operator B and the operator A can be attempted.

As shown in FIG. 4, the breakdown of how the maintenance contract cost was calculated may be displayed on the display screen of the maintenance contract cost. In addition, although not shown, advice information may be displayed that indicates which item should be improved to reduce the maintenance contract cost (which item causes the maintenance contract cost to increase).

[Calculation processing of maintenance contract cost]
Next, the details of the maintenance contract fee calculation process in step S15 will be described. FIG. 5 is a flow chart of the maintenance contract fee calculation process.

The acquisition unit 42a of the server device 40 acquires the contract information (S21). As shown in FIG. 3, the contract information is information received by the communication unit 41 and indicating the maintenance scope (that is, the contents of the maintenance contract).

Next, the assessment unit 42b makes an assessment based on the acquired contract information (S22). The assessment unit 42b determines assessment points such that the wider the range of maintenance indicated by the contract information, the higher the cost.

Next, the acquisition unit 42a acquires the specification information of the facility 21 (S23). The specification information includes information such as the model number, durability, and lifespan of the facility 21, for example. The contract management information in which the contract ID and the specification information of the facility 21 are linked is stored in the storage unit 43 in advance. The specification information of the equipment 21 linked to the contract information (contract ID) can be obtained.

Next, the assessment unit 42b performs assessment based on the acquired specification information (S24). The assessment unit 42b determines a predetermined assessment point for the specifications of the equipment 21 .

Next, the acquisition unit 42a acquires usage period information indicating the usage period of the equipment 21 (S25). The usage period information is, for example, information indicating the actual usage period (in other words, operating time) of the equipment 21 . The acquiring unit 42a can specify the actual usage period based on, for example, the measured value of the current or voltage output by the power supply device 26 among the measured values stored in the storage unit 43 in step S12. That is, the acquisition unit 42a can acquire the usage period information based on the measured value of current or voltage.

In addition to the usage period information, information indicating the period (number of years) from introduction of the equipment 21 to the present may be acquired regardless of the actual usage period. In this case, if the date of introduction of the equipment 21 is included in the contract management information stored in the storage unit 43, the acquisition unit 42a refers to the contract management information to obtain the current date since the equipment 21 was introduced. period can be specified. That is, the acquiring unit 42a can acquire information indicating the period from introduction of the equipment 21 to the present based on the contract management information. Such information is supplementarily used, for example, when usage period information cannot be acquired, but may be used together with usage period information.

Next, the assessment unit 42b makes an assessment based on the acquired usage period information (S26). The assessment unit 42b determines assessment points such that the longer the usage period indicated by the usage period information, the higher the cost. If information indicating the period from introduction of the equipment 21 to the present is acquired, an assessment based on such information is performed in step S26.

Next, the acquisition unit 42a acquires usage environment information indicating the usage environment of the facility 21 (S27). The usage environment information is information (measured values) sensed by a sensor. Among the measured values stored in the storage unit 43 in step S12, the usage environment information includes the measured temperature value output by the temperature sensor 22, the measured humidity value output by the humidity sensor 23, and the measured value output by the vibration sensor 24. Measured vibrations output by the noise sensor 25 , measured voltage output by the power supply 26 , and measured current output by the power supply 26 . The acquisition unit 42a can acquire these six types of measurement values from the storage unit 43 as usage environment information. Note that the acquisition unit 42a may acquire at least one of the six types of measured values as the usage environment information, and it is not essential to acquire all of the six types of measured values.

Next, the assessment unit 42b performs assessment based on the acquired usage environment information (S28). FIG. 6 is a diagram for explaining an assessment method based on usage environment information. FIG. 6 is a diagram for more specifically explaining the assessment method based on the environmental temperature, and shows time-series temperature data for the target period (the most recent one year). That is, the vertical axis of FIG. 6 indicates temperature, and the horizontal axis indicates time.

As shown in FIG. 6, the assessment unit 42b ranks the temperature time-series data (a plurality of measurement points) for each measurement point (that is, for each unit time) using a first threshold value and a second threshold value. For example, the assessment unit 42b determines that a measurement point whose temperature is less than the first threshold belongs to the use environment of rank A most suitable for operation of the equipment 21, and the temperature is greater than or equal to the first threshold and less than the second threshold. The measurement point is determined to belong to the standard rank B usage environment. In addition, the assessment unit 42b determines that the measurement points whose temperature is equal to or higher than the second threshold belong to the use environment of rank C, which is inappropriate for the operation of the facility 21. FIG. The assessment unit 42b counts the number of measurement points belonging to Rank A, Rank B, and Rank C, and performs weighted addition using weights determined for each rank, thereby determining assessment points. Assessment points are determined such that the more time spent in a favorable environment, the lower the cost (the more time spent in an unfavorable environment, the higher the cost).

Although three ranks (two thresholds) are set in the example of FIG. 6, three or more ranks may be set. Also, at least two ranks (one threshold) may be set. If only two ranks are provided, a simpler assessment method may be employed, such as performing assessment based on the frequency of occurrence of measurement points belonging to inappropriate usage environments.

In the above description, it was explained that the equipment 21 is suitable for use in a low-temperature environment and inappropriate for use in a high-temperature environment. However, the facility 21 is suitable for use in a high temperature environment, and may not be suitable for use in a low temperature environment. In this case, the higher the temperature of the measurement point, the more appropriate it is determined to belong to the rank.

In addition, the facility 21 is suitably used within a specific temperature range (for example, 0° C. or higher and 40° C. or lower), and is used in a temperature environment away from the specific temperature range regardless of whether the temperature is high or low. Sometimes it is inappropriate to be In this case, a measurement point is judged to belong to an appropriate rank when it belongs to a specific temperature range, and it is judged to belong to an inappropriate rank as the measured value is farther from the specific temperature range regardless of whether the temperature is high or low. be done.

In addition, although FIG. 6 shows an assessment method based on the temperature measurement value among the six types of measurement values, other measurement values can also be assessed by a similar method.

Next, the acquiring unit 42a acquires maintenance implementation information indicating what kind of maintenance was performed on the equipment 21 by the business operator B (the business operator that provides the maintenance service) during the target period (S29). The maintenance implementation information includes contractual maintenance implementation information that indicates what kind of maintenance was performed within the scope of the maintenance contract, and non-contract maintenance implementation information that indicates what kind of maintenance was performed outside the scope of the maintenance contract. (in other words, spot maintenance information). Such maintenance implementation information is stored, for example, in the storage unit 43 of the server device 40 each time maintenance is performed. The acquisition unit 42 a can acquire maintenance implementation information from the storage unit 43 .

Next, the assessment unit 42b makes an assessment based on the acquired maintenance implementation information (S30). The assessment unit 42b determines assessment points so as to reduce the cost because the need for maintenance of the facility 21 is reduced when the maintenance implementation information indicates that parts of the facility 21 are being replaced. Also, when the maintenance implementation information indicates that maintenance has been performed frequently, the assessment unit 42b determines assessment points so that the cost is high. In this way, the assessment unit 42b determines assessment points based on the substantive content of the acquired maintenance implementation information.

Next, the acquisition unit 42a acquires user maintenance execution information indicating what kind of maintenance was performed on the equipment 21 by the user (user a who belongs to the business operator A) who receives the provision of the maintenance service. (S31). The user maintenance implementation information is, for example, information indicating whether or not the user a is properly performing prescribed maintenance (care) such as regular replacement of an air filter. For example, if a sensor senses whether or not the air filter has been replaced, and the sensing result is transmitted from the first information terminal 27 to the server device 40, the information processing unit 42 stores the sensing result in the storage unit 43 for user maintenance. It can be stored as implementation information. The user maintenance execution information may be stored in the storage unit 43 by self-declaration by the user a. The acquisition unit 42 a can acquire maintenance implementation information from the storage unit 43 .

If the facility 21 is an air conditioner and the air filter is not replaced, the power consumption will increase. Therefore, it is also possible to estimate whether or not the air filter has been replaced based on the measured values of power output by the power supply device 26 (the measured values of current and the measured values of voltage).

Next, the assessment unit 42b makes an assessment based on the acquired user maintenance execution information (S32). The assessment unit 42b determines assessment points based on the user maintenance implementation information so that the more appropriately the user a performs the maintenance (the more the user a performs the maintenance as prescribed), the lower the cost.

Next, the calculator 42c calculates the maintenance contract fee based on the assessment points determined in steps S24, S26, S28, S30, and S32 (S33). The calculation unit 42c converts the sum of assessment points into maintenance contract costs, for example, using a predetermined amount of money per unit assessment point.

As described above, the maintenance contract cost calculation system 10 calculates the maintenance contract cost based on contract information, specification information, usage period information, usage environment information, maintenance implementation information, and user maintenance implementation information. The maintenance contract cost calculation system 10 may calculate the maintenance contract cost based on at least one of contract information, specification information, usage period information, usage environment information, maintenance implementation information, and user maintenance implementation information. .

[Energy cost calculation process]
A maintenance contract may be concluded that includes the energy cost required to operate the facility 21 (for example, the amount of electricity bills to be paid for the next one year). In other words, maintenance contract costs may include energy costs for the duration of the contract. The calculation processing of the energy cost in such a case will be described. FIG. 7 is a flowchart of energy cost calculation processing.

A case where the equipment 21 is an air conditioning equipment will be described. The acquisition unit 42a acquires temperature information provided by the weather information providing server 50 (S41). The acquisition unit 42a also acquires the amount of energy used (measured value of power consumption) provided by the power supply device 26 (S42). The calculation unit 42c evaluates the energy saving efforts of the business operator A who uses the facility 21 based on the obtained temperature information and the obtained energy consumption (S43), and calculates the energy cost based on the evaluation result. (S44).

Specifically, the calculation unit 42c identifies the change in temperature during the target period based on the acquired temperature information. The calculation unit 42c sets the energy cost to a predetermined amount when the identified temperature change is larger than in an average year and the amount of energy used in the target period is larger than in an average year. On the other hand, if the specified temperature fluctuations are larger than usual, but the amount of energy used during the target period is the same as usual or less, it is determined that business operator A is making efforts to save energy. , to make the energy cost lower than the amount given above.

In addition, the calculation unit 42c sets the energy cost to a predetermined amount when the identified temperature fluctuation is smaller than the usual year and the energy consumption in the target period is the same as the usual year or less than the usual year. On the other hand, if the specified temperature fluctuations are smaller than usual, but the amount of energy used during the target period is higher than usual, it will be determined that business operator A is not making efforts to save energy, and Make the cost higher than the above default amount.

In this way, the calculation unit 42c evaluates the efforts of the business operator A who uses the facility 21 to save energy based on the temperature information provided by the weather information providing server 50 and the actual energy consumption. Energy costs can be calculated based on the results.

In the above example, the magnitude of temperature variation is used as the determination criterion, but other parameters such as average temperature may be used instead of temperature variation.

[Modification]
In the above embodiment, the maintenance contract cost calculation system 10 was used for estimating the maintenance contract cost, but it may be used for reviewing the maintenance contract cost. For example, operator A pays operator B an amount C1 when concluding a maintenance contract. When the maintenance contract expires, the maintenance contract cost calculation system 10 recalculates the maintenance contract cost using information (measured values of sensors, etc.) during the contract period. Specifically, the maintenance contract cost calculation system 10 executes at least part of the processing of the flowchart of FIG. Assuming that the calculated amount of money is C2, the difference between the amount of money C1 and the amount of money C2 is cashed back or additionally charged to the business operator A. At this time, the difference between the amount C1 and the amount C2 may be displayed on the display unit 32 of the second information terminal 30 .

In this manner, the maintenance contract cost calculation system 10 may be used for estimating maintenance contract costs, and may be used for reviewing maintenance contract costs.

[Effects, etc.]
