Description

  The present invention relates to a maintenance fee calculation device and a maintenance fee calculation method for passenger conveyors such as escalators and moving walkways.

  For example, there are several types of escalator maintenance contracts. Among them, the full maintenance contract is a typical contract form. The full maintenance contract included regular inspections of passenger conveyors and free replacement of deteriorated and consumable parts, and was set for a fixed amount per escalator. However, the operating time of the escalator varies depending on the setting destination. For example, an escalator installed in a transportation facility such as a railway is often operated from the first train to the last train, and generally operates for 20 hours or more per day. On the other hand, an escalator installed in a commercial facility such as a department store is operated from opening to closing and is often about 10 hours per day. If the operating time is different in this way, there is a difference in the deterioration and consumption of parts, so some customers have an unfair feeling in a full maintenance contract with the same fee.

Therefore, the present applicant has previously proposed a method of calculating a maintenance fee based on the actual operating time of the escalator in order to eliminate such unfairness (see Patent Document 1).
JP 2005-119857 A

  However, the deterioration / consumption of parts does not depend only on the operation time, but also depends on the load state when the escalator is used. That is, even if the operating time of the escalator is the same, if the load during operation is large, the deterioration and wear of the parts progress. Therefore, there may be a feeling of unfairness in the calculation of the maintenance fee based only on the operation time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor maintenance fee calculation device and a maintenance fee calculation method capable of calculating a fair maintenance fee.

  A first feature of the present invention is a passenger conveyor maintenance fee calculation device, a power consumption recording means for storing power consumption and operating time of a passenger conveyor, and a maintenance period input means for inputting maintenance period data. And a maintenance fee calculation data setting unit to which setting data necessary for calculating the maintenance fee is input, and power consumption and operating time data based on the corresponding period data from the maintenance period input means are input from the power consumption recording means. And a maintenance fee calculation unit that inputs necessary setting data from the maintenance fee calculation data setting unit and calculates a maintenance fee based on power consumption and operating time data based on the setting data, and the maintenance fee calculation unit And a data output means for outputting the maintenance fee calculated by the above.

  The second feature of the present invention is a passenger conveyor maintenance fee calculation method for measuring and setting the power consumption and operating time of a passenger conveyor within a predetermined maintenance period set as a maintenance fee calculation period. The gist is to calculate a maintenance fee based on power consumption and operating time based on data.

  According to the present invention, attention is paid to the fact that the load during operation of the passenger conveyor is substantially proportional to its power consumption, and the maintenance fee is calculated based on the operation time and power consumption of the passenger conveyor. The maintenance fee can be calculated considering the load status. Accordingly, it is possible to calculate a maintenance fee with a sense of fairness.

  Embodiments of the present invention will be described below.

  1 and 2 show an embodiment of the present invention, FIG. 1 is an overall schematic configuration diagram in which a maintenance fee calculation device according to the present invention is applied to an escalator, and FIG. 2 is a circuit block diagram of the maintenance fee calculation device.

  In FIG. 1, an escalator 1 for ascending operation, which is a passenger conveyor, includes a truss structure 2 disposed between an upper floor elevator floor (not shown) and a lower floor elevator floor (not shown), and the interior of the truss structure 2. In addition, a pair of step chain gears 3 and 4 provided at the positions of the upper floor elevator and the lower floor elevator and an endless shape (not shown) spanned between the pair of step chain gears 3 and 4 A step chain, a plurality of steps 6 supported in a chain on the step chain, a pair of balustrades 7 erected on the left and right positions of the upper surface of the truss structure 2, and a trajectory of movement of the pair of balustrades 7 And a pair of moving handrails 8.

  One step chain gear 3 and the rotation shaft 10 a of the drive motor 10 are connected via a drive belt 11. When the drive motor 10 is driven, each step 6 moves on a predetermined infinite trajectory that is reversed at the position of the upper floor elevator and the lower floor elevator by the movement of the step chain. Further, the step chain gear 3 and the moving handrail 8 are connected by connecting means (not shown), and the moving handrail 8 also moves in conjunction with the movement of the step chain.

  The drive motor 10 is controlled by a control device 13 that receives power supply from the power receiving panel 12.

  As shown in FIG. 2, the control device 13 includes a power meter 20, a power consumption recording unit 21, a maintenance period input unit 22, a maintenance fee calculation data setting unit 23, a maintenance fee calculation unit 24, and a data output unit. 25. The wattmeter 20 measures the power supplied to the drive motor 10 and outputs the measured power data to the power consumption recording means 21.

  The power consumption recording means 21 has a built-in timer, and records the power consumption and operating time data (power consumption × operating time = power consumption B) of the drive motor 10, for example, in units of days. The power consumption recording means 21 outputs the recorded power consumption B in response to a request from the maintenance fee calculation means 24.

  The maintenance period input means 22 receives maintenance period period data (one month unit in this embodiment) negotiated between the maintenance company and the contractor. The maintenance period input unit 22 outputs the input maintenance period data in response to a request from the maintenance fee calculation unit 24.

  The maintenance fee calculation data setting unit 23 receives setting data (in this embodiment, fixed fee F, average power consumption A, maximum value M at 100% operation) negotiated between the maintenance company and the contractor. Has been. The maintenance fee calculation data setting unit 23 outputs the input setting data in response to a request from the maintenance fee calculation means 24.

  When there is a maintenance charge calculation command, the maintenance charge calculation means 24 inputs desired maintenance period data from the maintenance period input means 22 and consumes power consumption and operating time data in this maintenance period, that is, power consumption B. Input from the power recording means 21 and necessary setting data from the maintenance fee calculation data setting unit 23. Then, a maintenance fee based on power consumption and operating time data is calculated based on the setting data.

  Hereinafter, an example of calculating a maintenance fee will be described. The maintenance fee is composed of a fixed fee (F) and a variable fee. When the average power consumption of the escalator 1 is set to AkW, the variable charge is set so that AkW × 30 days × 24h = 720 AkWh becomes 100%. Then, assuming that the maximum value of the variable charge in 100% operation status is M yen, the fixed charge is F yen, and the power consumption actually accumulated during this period is BkW, the maintenance charge Y is Y = F + (B ÷ 720A ) × M.

  However, even if the load on the escalator 1 increases for some reason and B exceeds 270A, B = 270A and the maximum value of the variable charge is M yen.

  In such a maintenance fee calculation method, necessary setting data are F, A, and M, and these data are determined by a contract between the maintenance company and the contracted party. Then, the determined F, A, and M values are input to the maintenance fee calculation data setting unit 23. The method for calculating the maintenance fee described above is an example, and any method may be used as long as the maintenance fee is calculated based on the power consumption and operation time data based on the setting data. The maintenance fee calculation unit 24 outputs the calculated maintenance fee to the data output unit 25.

  The data output means 25 is configured to record the input maintenance fee data and to transfer the maintenance fee data to a connection destination (for example, a maintenance company or a contract destination) via a communication means such as the Internet. The data output means 25 may be an external display device such as a display device or a printer that visually displays a maintenance fee, in addition to such an external recording device (for example, a personal computer).

  As described above, in the present invention, since the maintenance fee is calculated based on the setting data based on the operating time of the escalator 1 and the power consumption proportional to the load when carrying the passenger, the load status when the escalator 1 is operating is calculated. A maintenance fee can be calculated. Accordingly, it is possible to calculate a maintenance fee with a sense of fairness.

  In this embodiment, the data output means 25 is composed of an external recording device capable of transferring data via communication means such as the Internet, so that the maintenance fee can be known without going to the place where the escalator 1 is installed. it can.

  In addition, although this embodiment demonstrated the case where the passenger conveyor was the escalator 1, it is needless to say that it is applicable similarly to passenger conveyors (for example, a moving sidewalk) other than an escalator. The passenger conveyor may be set indoors or outdoors. Furthermore, the exterior member and balustrade 7 of the truss structure 2 may be formed of any member of a translucent member and an opaque member.

(Other embodiments)
In the above-described embodiment, the escalator having the ascending operation setting has been described. However, some escalators have the descending operation setting. In the case of an escalator set for descending operation, the load fluctuation is not proportional to the fluctuation of the power consumption. However, the escalator for the descending operation is not installed alone, but is always provided with the escalator for the ascending operation. In addition, although there is a time shift in both transportation and commercial facilities, the amount of movement of people is considered to be equivalent to an increase and a decrease. Accordingly, the maintenance fee may be calculated by assuming that the load state applied to the escalator for the descending operation is equivalent to the escalator for the ascending operation provided therewith.

It is the whole schematic block diagram to which the maintenance charge calculation device concerning an embodiment of the invention is applied. 1 is a circuit block diagram of a maintenance fee calculation apparatus according to an embodiment of the present invention.
