FIG. It is a table | surface which shows the kind and content of degeneration operation corresponding to each device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, a courier service will be described as an example of a specific business in which a mobile terminal device is used outdoors. FIG. 1 is a diagram illustrating an entire collection and delivery system 1 to which the mobile terminal device of the present embodiment is applied. The collection / delivery system 1 is a management system for collecting a property deposited from a customer and delivering it to a designated customer.

  The collection and delivery system 1 includes a portable terminal device 40 (also abbreviated as a portable terminal) carried by a delivery person, a system center 10 and a collection and delivery center 20. The system center 10 is a base that manages the entire collection and delivery system 1 and is a data center in which a server system 12 and a server DB (database) 14 are installed.

  The server system 12 manages data of delivery / collection routes and delivery / collection (also called collection) properties registered at the collection / delivery center. The server DB 14 stores data managed by the server system.

  Here, a property means a “item” to be delivered / collected. Objects to be transported, such as cash and valuables, are stored in containers such as cassettes, bags, envelopes, etc., and are managed in units of containers in the “collection / collection center” to “collection / delivery destination”. The route is defined as a route and time for delivery / collection by connecting cars and people.

  The collection / delivery center 20 is a delivery company's warehouse and work place, where a property is delivered / prepared for collection. The collection / delivery center 20 is provided with a PC 22 and a printer 24. The PC 22 registers the delivery / luggage collection in the collection / delivery center 20 and performs data transmission / reception (P1, P2) related to the delivery / luggage collection via the wired network 3 with the server system 12. The PC 22 is wirelessly connected to the mobile terminal 40 to perform data transmission / reception. The printer 24 is connected to the PC 22 and prints a slip 120 on which a property number (including a barcode) is printed. A slip 120 printed at the collection / delivery center 20 is attached to each property.

  The portable terminal 40 is a terminal carried by a delivery person at the time of collection and delivery, and performs route instruction, property management, registration of delivery, and the like, and is also referred to as HHT (Hand Held Terminal). The delivery person uses the portable terminal 40 to read the article number (barcode) of the slip attached to the article assigned for each route, and checks the read data with the DB contents in the portable terminal 40. And manage delivery and collection.

  The portable terminal 40 is connected to the server system 12 through the wireless network 2 outdoors, and delivery and collection data are transmitted to the server system 12. The wireless network 2 includes a VPN (Virtual Private Network) and a PPP (Point to Point Protocol).

  In the collection / delivery center 20, data related to collection / delivery is downloaded from the server system 12 of the system center 10 to the PC 22 (P1). A slip 120 is printed for each property from the printer 24 connected to the PC 22 based on the downloaded collection and delivery data. A bar code 120a corresponding to the property number is also printed on the slip 120. Of the printed slips 120, the delivery slips are affixed to the corresponding delivery property 100 by the delivery staff at the collection and delivery center 20. Of the printed voucher 120, the voucher for collection is taken out by the delivery person. In the middle of the delivery route, the delivery member goes to the customer who requested in advance and collects the property. At that time, a collection slip is attached to the package collection.

  Further, the delivery property data and the collected luggage data, which are in charge of each person, are downloaded from the server system 12 to the delivery person's portable terminal 40 together with the route data (P3). It is stored in the delivery person's mobile terminal 40 as the property 58a in the route. The property 58a in the route is data relating to the property number of the property for which the delivery person is in charge of collection and delivery and the corresponding collection and delivery route. The delivery person reads the barcode 120a of the slip attached to the delivery item with his / her mobile terminal 40 (departure reading), registers it in the route property 58a, and then goes to delivery.

  When the delivery member delivers the delivery item 100 to the delivery destination customer, the delivery member reads the barcode 120a from the slip 120 attached to the delivery item 100 (delivery reading). In the portable terminal 40, the read data is registered in the property 58a in the route as a delivery result. Then, the delivery record data registered in the property 58a in the route is transmitted from the portable terminal 40 to the server system 12 via the wireless network 2, and the delivery record is registered in the server DB 14 (P4).

  The delivery person also reads the barcode 120a from the slip 120 when receiving the package collection item 110 from the customer (collection reading). In the portable terminal 40, the read data is registered in the property 58a in the route as a collection record. Further, the collection record data is transmitted from the portable terminal 40 to the server system 12 via the wireless network 2, and the collection record is registered in the server DB 14 (P5).

  The collection item 110 is taken back to the collection / delivery center 20 by a delivery person, and the bar code 120a is read by the portable terminal 40 when the collection is performed at the collection / delivery center 20. The read data is transmitted to the server system 12 via the wireless network 2, and the warehousing record is registered in the server DB 14 (P6). The outline of the collection and delivery system 1 has been described above.

  FIG. 2 is a diagram illustrating a main block of the mobile terminal (HHT) 40 and an appearance example of the mobile terminal 40. The portable terminal 40 includes a controller 50, a touch panel 60, a keyboard 62, a communication unit 64, an audio / buzzer output unit 66, a barcode scanner 68, a vibration unit 70, a camera 72, a printer 74, a telephone unit 76, a power control unit 78, and a battery. Various built-in devices such as 80.

  The controller 50 is a control unit that comprehensively controls the mobile terminal 40 as a whole. The touch panel 60 displays an operator operation screen on the screen and detects a position touched on the screen. The keyboard 62 is a push button. The operation keys include ten keys (0 to 9), cross keys (← ↑ → ↓), function keys (F1 to Fn), a clear key, power ON / OFF, and the like.

  The communication unit 64 is an interface for performing data communication between the mobile terminal 40 and an external device. As a communication format, it corresponds to WAN (Wide Area Network external communication: data communication network such as telephone network and Internet) and LAN (Local Area Network internal communication: wireless LAN, infrared, Bluetooth (registered trademark), wired LAN).

  The sound / buzzer output unit 66 outputs an operation sound, a guide sound, and an alarm sound, and alerts the operator to confirm the operation and other attention. The barcode scanner 68 reads the barcode 120a of the slip 120 pasted on the “property” to be collected and delivered.

  The vibration unit 70 informs the operator of confirmation and warning about the operation by vibration as well as vision and hearing. The camera 72 records evidence such as a property to be collected and delivered, a work place, and a receipt as an image (photo).

  The printer 74 prints a delivery certificate, a receipt certificate, and a copy thereof on a receipt according to the property to be collected and delivered. The telephone unit 76 is for voice communication with the collection / delivery destination and the collection / delivery center 20.

  The power supply control unit 78 converts the voltage of the battery 80 into a voltage that matches each unit and supplies it to each unit of the device. In addition, the power supply control unit 78 detects the voltage of the battery 80 and calculates a signal corresponding to the detected voltage to the controller 50 in order to calculate the remaining battery level.

  The controller 50 includes an OS 52, a CPU 54, a memory 56, and a disk 58. The OS 52 is software that manages the entire computer system. The CPU 54 reads a control application program from the disk 58 and performs control processing of the portable terminal 40 according to the application program.

  The memory 56 is a temporary storage unit for data expansion, and is, for example, a DRAM. The disk 58 is a non-volatile storage unit and stores a control application program and various data. The disc 58 stores a property 58a in the route for collection and delivery. The disk 58 may be a flash memory.

  The CPU 54 includes a battery remaining amount calculation unit 54a and a degeneration operation unit 54b. The battery remaining amount calculation unit 54a calculates the remaining amount of battery power (hereinafter referred to as the remaining battery amount) in accordance with the battery voltage notified from the power supply control unit 78.

  The degeneration operation unit 54b determines whether or not the battery runs out based on the number of properties scheduled to be collected and delivered (or remaining collection and delivery) and the remaining battery level, and restricts the function of the built-in device. The degeneration operation unit 54b calculates the number of properties scheduled for collection / delivery (or remaining collection / delivery) from the property 58a in the route, and uses the result of the battery remaining amount calculation unit 54a for the remaining battery level. Further, the degeneration operation unit 54b may change the contents to be restricted between the delivery business and the collection / delivery business.

  In other words, the degeneration operation unit 54b calculates the necessary battery power necessary for completing the planned operation from the progress of the operation and the battery consumption per unit operation, and compares the remaining battery power and the required battery power. When battery shortage is expected, degenerate operation is performed to limit the use or function of the device. Further, the degeneration operation unit 54b may change the use or function restriction of the device according to the type of business.

  FIG. 3 is a flowchart for explaining the property collection and delivery procedure. A contract for property delivery / collection is registered (if new, master registration) (step S10). When receiving a property delivery / collection request from a customer, the server system 12 registers the requested property in the server DB 14. If the requested customer is a new customer, the server system 12 registers it in the master.

  The server system 12 creates a property delivery / collection plan based on the property request (step S12). The server system 12 creates a delivery / collection matter information master D1 and a delivery / collection route master D2 as property delivery / collection plans. The delivery / collection route master is data defining the route / time of delivery / collection.

  FIG. 4 is a table for explaining the contents of the four data created for property delivery / collection. Table 1 in FIG. 4 shows main items and contents of the delivery / luggage collection information master D1. In the delivery / luggage collection information master D1, a contract customer name, a store name, an address, a delivery / collection type, a package form, the number, and the like are registered. The “key” in the table is key information for preventing the property from being doubled. Once the contract customer and store are confirmed, the property is identified. Table 2 in FIG. 4 shows main items and contents of the delivery / pickup route master D2. In the delivery / collection route master D2, the collection / delivery center 20, the route, the district, and the person in charge (delivery person) are registered.

  Returning to FIG. The server system 12 assigns the property and route, then assigns the property No and the route (step S14). The server system 12 creates delivery / collection schedule (route unit) data D3 from the delivery / collection matter information master D1 and the delivery / collection route master D2. Delivery / pickup schedule (route unit) data D3 is a collection of delivery / luggage collection data by district, and a specific person in charge (delivery person) and collection / delivery route are pasted on the delivery / pickup collection data organized by district. It is attached data.

  Delivery / collection schedule (route unit) data D3 is downloaded to the portable terminal 40 (step S16). The delivery person inputs his / her ID number to the portable terminal 40 and communicates with the server system 12, whereby the delivery / collection schedule (route unit) data D <b> 3 in charge is downloaded from the server system 12. The delivery person's portable terminal 40 stores delivery / collection schedule data D3 in the route. Table 3 in FIG. 4 is a table showing main items and contents of delivery / collection schedule data D3 in the route. Items are property number, route, collection / delivery date and time, delivery / collection. The delivery / collection schedule data D3 becomes a part of the property 58a in the route.

  FIG. 5 is a diagram illustrating an example of a screen displayed on the mobile terminal 40. At the start of business, a screen indicating “0 business start” is displayed on the screen of the touch panel 60. A business menu list is displayed on the business start screen. When the business start button 60a is touched by the delivery person on the 0 business start screen, the delivery / collection schedule (route unit) data D3 is downloaded from the server system 12 to the portable terminal 40. During the download, a screen indicated by “1 download” is displayed on the touch panel 60. After downloading, a screen indicated by “2 menu” is displayed on the screen of the touch panel 60.

  Then, in the delivery person's mobile terminal 40, delivery / collection record data D4 in the route is created corresponding to the delivery / collection schedule data D3 in the route. Table 4 in FIG. 4 is a table showing main items and contents of the delivery / collection record data D4 in the route.

  Items are property number, route, mobile terminal, actual date and time, history, mode, and data status. The history records whether the property is in preparation / shipping / delivery status (state) in delivery, and in the collection, records the status (state) in collection / receipt The In the mode, it is recorded whether it is in a degenerate operation state. The delivery / pickup schedule data D3 and the delivery / pickup record data D4 constitute a property 58a in the route.

  When the property preparation button 60b is touched by the delivery person on the screen indicated by “2 menu” in FIG. 5, a screen (a) indicated by “3 property scan” is displayed. On the screen (a) shown by “3 property scan”, preparation for collection and delivery (scanning of the property number in the route) is performed (step S18). At the collection / delivery center 20, the delivery person scans the property number (bar code 120a) of the slip 120 attached to the property for each property in charge with his / her mobile terminal 40. At the same time, the slip 120 of the property to be collected on the route is also scanned. By this delivery property scan, the property status is registered as delivery in the “history” of the delivery / pickup record data D4.

  In addition, the screen (b) showing “3 property scan” is a screen displayed in the actual collection business, and the screen showing “4 actual data upload” is a screen displayed in the actual collection business, These will be described later.

The portable terminal 40 calculates the required battery amount from the scanned property amount (step S20). After scanning all delivery items and package collection slips, the degeneration operation unit 54b of the CPU 54 calculates the required battery power calculated from the property amount. The following is a formula for calculating the required battery power required for collection and delivery.
Required battery power = (number of deliveries + number of packages) x power consumption per collection / delivery (Formula 1)
This is a case where there is no significant difference in power consumption between delivery and collection. The power consumption per collection / delivery here (battery power consumption per unit operation) corresponds to the power consumption in the full operation mode of FIG.

Also, if the power consumption of the mobile terminal 40 is different between delivery and collection,
Required battery power = (number of deliveries x power consumption per delivery) + (number of luggage collection x power consumption per collection) (Equation 2)
It is good. Further, the battery remaining amount calculation unit 54a of the CPU 54 calculates the remaining amount of the built-in battery.

  The degeneration operation unit 54b determines whether battery shortage is expected when all cases are collected and delivered (step S22). The degeneration operation unit 54b compares the battery power required for collection and delivery (the above formula 1 or 2) with the calculated remaining battery level, and determines whether or not the battery runs out.

  If the degeneration operation unit 54b determines that battery shortage is expected when all cases have been processed (Yes in step S22), it outputs a battery shortage assumption message (step S24). For example, “battery shortage is expected” is displayed on the screen of the touch panel 60. Then, the degenerate operation unit 54b inquires of the delivery person whether to select the degenerate operation, and determines whether the degenerate operation is selected (step S26).

  If the degenerate operation unit 54b determines that the degenerate operation is selected (Yes in step S26), the degenerate operation unit 54b sets the degenerate operation (step S28). FIG. 6 is a table showing the types and contents of the degenerate operation corresponding to each built-in device. The table in FIG. 6 is an example of the degeneration operation corresponding to each built-in device, and lists the functions that are restricted during the degeneration operation compared to the normal function (when degeneration operation is not performed) of each built-in device. Is.

  The “controller” in FIG. 6 is an item related to the function limitation of the OS 52, CPU 54, memory 56, and disk 58 included in the controller 50. The “screen” is an item related to the function limitation of “5-screen display (luminance)” and “6-touch panel” of the touch panel 60. “7 keyboard” is an item relating to the function restriction of the keyboard 62.

  The “communication device” is an item related to the function restriction of the communication unit 64 and is divided into “8 WAN”, “9 wireless LAN”, and “10 wired LAN”. “Sound” is an item relating to the function restriction of the voice / buzzer output unit 66, and is divided into “11 voice guide” and “12 buzzer”. “13 Scanner (Barcode)” is an item relating to the function restriction of the barcode scanner 68.

  “14 vibration” is an item related to the function restriction of the vibration unit 70. “15 cameras” is an item relating to the function restriction of the camera 72. “16 printer (printing)” is an item relating to the function restriction of the printer 74. “17 telephones” is an item relating to the function restriction of the telephone unit 76.

  The column of power consumption indicates a built-in device with relatively high power consumption, and a built-in device to which “high” is attached or a partial function of the built-in device indicates that power consumption is relatively high. The essential function indicates a function that is indispensable for the collection and delivery business among the built-in devices. Either “6 touch panel” or “7 keyboard” is indispensable. In addition, any one of “8 WAN”, “9 wireless LAN”, and “10 wired LAN” is indispensable.

  The column of normal operation (full operation mode) indicates functions executed by each built-in device during normal operation that is not degenerate operation. “◯” indicates that the function is fully executed, “Δ” indicates that the function is restricted, and “X” indicates that the function is stopped. In normal operation (full operation), the functions of each device are fully executed.

  In “1OS”, the OS 52 shifts to the sleep mode when there is no input for a certain period for energy saving, but in normal operation, the certain period is set longer (for example, 3 minutes). In “5-screen display (luminance)”, the luminance (backlight) is set to the maximum. In “8 WAN”, the regular communication interval is set short (for example, 5 minutes). The regular communication interval is a regular communication time interval between the mobile terminal 40 and the server system 12. Delivery status data and pickup request data are frequently exchanged between the portable terminal 40 and the server system 12.

  For the reduced operation, two modes are prepared: a simple operation mode and a minimum operation mode that can further reduce power consumption than the simple operation mode. The simple operation mode is divided into a simple operation 1 mode for delivery and a simple operation 2 mode for collection. This is because the contents of the degenerate operation of the device can be made different between the delivery business and the collection business.

  In the simple operation mode, “1OS” sets the sleep on interval to an intermediate time (1 minute) shorter than the full operation mode. “5 screens (luminance)” is set to “middle” slightly darker than the full operation mode.

  In addition, the regular communication interval of “8 WAN” is set longer (for example, 10 minutes) in the simple operation 1 mode (delivery) than in the full operation mode. In the simple operation 2 mode (collection), the periodic communication interval of “8 WAN” is set to cancel. This is because the collection data may be transmitted to the server system 12 after returning to the collection / delivery center 20. In addition, “10 wired LAN” is set to unused in the normal operation mode.

  “16 printer (printing)” is set not to issue a receipt on the spot in the simple operation 1 mode (delivery). The receipt will be issued at a later date and arranged to be sent to the customer. This is because if the property is delivered, the need for a receipt is low.

  Further, “16 printer (printing)” is set to thinning printing in the simple operation 2 mode (collection). It is set to print out less important information (for example, customer's address). In addition, the built-in devices “9 wireless LAN”, “11 voice guide”, “14 vibration”, “15 camera”, and “17 telephone” are set to stop use.

  In the minimum operation mode, “1OS” sets the sleep on interval to a shorter time (20 seconds) than in the simple operation mode. “5 screens (luminance)” is set to “small” which is darker than the simple operation mode.

  “6 touch panel” is set to stop use. This is because if “7 keyboard” is valid, input is possible. For “8 WAN”, the periodic communication is stopped regardless of delivery / collection. The built-in devices “9 wireless LAN”, “11 voice guide”, “14 vibration”, “15 camera”, and “17 telephone” are set to be stopped in the same manner as in the simple operation mode. Further, “11 buzzer” and “16 printer (printing)” are also set to stop using.

  The power consumption for processing one case (battery power per unit of work) for each power consumption in the simple operation 1 mode, simple operation 2 mode, and minimum operation mode when the power consumption in the full operation mode is 100%. An example is shown in the table below FIG.

  As described above, in the simple operation 2 mode (collection), compared with the simple operation 1 mode (delivery), the periodic communication and the print stop can be executed to further reduce the power consumption per item. . In the full operation mode and the minimum operation mode, the power consumption of the delivery operation and the collection operation is the same. Further, in the minimum operation mode, since the function restrictions of the delivery business and the collection business are made the same, there is no difference in power consumption.

Returning to FIG. 3A. When the degeneration operation is set in step S28 described above, the degeneration operation unit 54b first calculates the required battery power in the simple operation mode.
Required battery power = (number of deliveries x power consumption in simple operation 1 mode (delivery)) + (number of items collected x power consumption in simple operation 2 mode (collection)) (Equation 3)

  If the degeneration operation unit 54b determines that the calculated required battery power in the simple operation mode is greater than the remaining battery amount, the degeneration operation unit 54b sets the degeneration operation in the simple operation mode.

If the degeneration operation unit 54b determines that the calculated required battery power in the simple operation mode is not greater than the remaining battery amount, the degeneration operation unit 54b calculates the required battery power in the minimum operation mode.
Required battery power = (number of deliveries + number of items collected) x minimum operation power consumption (Equation 4)

  When the degeneration operation unit 54b determines that the calculated required battery power in the minimum operation mode> the remaining battery amount, the degeneration operation unit 54b sets the degeneration operation in the minimum operation mode. The degeneration operation unit 54b displays an alarm when determining that the calculated required battery power in the minimum operation mode is not greater than the remaining battery amount.

  When it is determined that the degenerate operation is not selected (step S26 No), the process returns to step S14. Alternatively, when it is determined that battery shortage is not expected even when all cases are processed (No in step S22), or after the end of step S28, the collection and delivery work is started (step S30). The delivery member starts collection and delivery in order according to the route of the delivery / collection schedule data D3.

  The delivery member carries out the collection and delivery work, scans the property number, and delivers the property to the customer (step S32). In the case of the collection work, the property number is read and the collection process is performed on the screen (b) shown in “3 property scan” in FIG. Then, the record data that has been collected / delivered during the collection / delivery work is transmitted to the server system 12 as appropriate, and during the transmission, a screen shown in “4 record upload” of FIG. 5 is displayed.

The degeneration operation unit 54b calculates whether or not the battery runs short from the remaining amount of collection / delivery, for example, every time collection / delivery is completed during collection / delivery (step S34). The remaining battery level calculation unit 54a calculates the current remaining battery level. The degeneration operation unit 54b calculates the required battery power using the following equation. Here, it is assumed that the degeneration operation has not yet been entered. Here, it is assumed that there is no significant difference in power consumption between delivery and collection, and is an expression corresponding to the above-described expression (1).
Required battery power = (Number of remaining deliveries + number of uncollected properties) x Power consumption per collection / delivery (Formula 5)

Alternatively, similar to the above equation (2),
Required battery power = (number of remaining deliveries x power consumption per delivery) + (number of remaining collections x power consumption per collection) (Equation 6)
It is good.

  The degeneration operation unit 54b determines whether a battery shortage is expected when the remaining property is processed (step S36). If the degeneration operation unit 54b determines that battery shortage is not expected when the remaining property is processed (step S36 No), it determines whether a battery shortage has actually occurred (step S38). In step S34 and step S36, it is determined whether or not there is a shortage in relation to the number of remaining properties, whereas in step S38, the remaining battery level is reduced to a predetermined value (for example, 30% or less) regardless of the number of remaining properties. Judge what happened.

  When it is determined that the battery shortage is expected when the remaining property is processed (Yes at Step S36), or when it is determined that the battery shortage actually occurs (Yes at Step S38), the degeneration operation unit 54b is short of the battery. The message is displayed on the screen of the touch panel 60 (step S40). Then, the degenerate operation is set (step S42).

  In setting the degeneration operation, the degeneration operation unit 54b selects either the simple operation mode or the minimum operation mode using an equation similar to Equation 3 or Equation 4 described in Step S28.

Required battery power = (number of remaining deliveries x power consumption in simple operation 1 mode (delivery)) + (number of remaining collections x power consumption in simple operation 2 mode (collection)) (Equation 7)
If the degeneration operation unit 54b determines that the calculated required battery power in the simple operation mode is greater than the remaining battery amount, the degeneration operation unit 54b sets the degeneration operation in the simple operation mode.

If the degeneration operation unit 54b determines that the calculated required battery power in the simple operation mode is not greater than the remaining battery amount, the degeneration operation unit 54b calculates the required battery power in the minimum operation mode.
Required battery power = (number of deliveries + number of packages) x minimum power consumption ... (Equation 8)

  When the degeneration operation unit 54b determines that the calculated required battery power in the minimum operation mode> the remaining battery amount, the degeneration operation unit 54b sets the degeneration operation in the minimum operation mode. The degeneration operation unit 54b displays an alarm when determining that the calculated required battery power in the minimum operation mode is not greater than the remaining battery amount.

  If the reduced operation has already been performed in the simple operation mode, the determination as to whether or not to enter the reduced operation may be omitted in step S34 and step S36. In addition, when the reduced operation is already performed in the minimum operation mode, the determination as to whether the simple operation mode according to (Expression 5) or (Expression 6) can be applied may be omitted.

  After step S42 or when it is determined that a battery shortage has not occurred (No in step S38), the portable terminal 40 periodically updates data with the server system 12 (step S44). The portable terminal 40 downloads additional collection data from the server system 12 and uploads the performance data to the server system 12. However, as described in the table of FIG. 6, when the collection data in the simple operation mode or the minimum operation mode is set, step S44 is jumped.

  Following step S44, the CPU 54 determines whether collection / delivery has ended (step S46), and if it determines that collection / delivery has not ended (step S46 No), the process returns to step S32. When the CPU 54 determines that the collection and delivery has been completed (step S46 Yes), the business is terminated and the portable terminal 40 is closed (step S48).

Listed at least are the effects achieved by the embodiment described above.
・ Compared the battery power required to complete the remaining amount of work and the current battery remaining amount, so that the degenerate operation was performed when the battery was low, so the situation where the battery runs out during work without relying on the intuition of the user It can be surely prevented.
・ Compare the remaining battery level with all tasks at the start of business, and also compare the remaining battery level with the remaining battery power during the job, so that the operation of the mobile terminal 40 can be continued until the last job is completed. Since 40 is operated, it is possible to cope with variations in battery consumption every time.
・ From work that can greatly reduce battery usage by changing the contents of degeneration depending on the business, it is possible to efficiently save battery as a whole by actively reducing battery usage.
・ If the battery consumption varies depending on the type of work, the remaining power is divided into the number of times or time for each type of work, and the battery power required for the remaining amount of work is calculated in detail. It can be calculated accurately.

And in the said embodiment, the following deformation | transformation and addition are possible.
The mobile terminal 40 may notify the server system 12 that the reduced operation is started when the reduced operation is started. In the server system 12, the mobile terminal 40 that has entered the degraded operation may be subjected to a different degradation response process. For example, the regular communication from the server system 12 to the portable terminal 40 may be stopped or the content may be changed.
・ Two types of business, delivery and collection, have been described, but there are other delivery services for mail services such as catalogs. Unlike delivery of properties, e-mail flights do not require customer acceptance, can be processed more easily than regular properties, and consume less power on the mobile terminal 40 when processing one item. Degenerate operation for mail service can be made different from delivery and collection.
In addition, the example of the courier service has been described as a specific example in which the mobile terminal 40 is used, but the present invention may be applied to other operations such as gas meter reading, vending machine inspection, and product replenishment.
Although the battery remaining amount calculation unit 54a and the degeneration operation unit 54b have been described as being based on software processing by the CPU, some or all of them may be realized by hardware processing.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, all the constituent elements shown in the embodiments may be appropriately combined. Furthermore, constituent elements over different embodiments may be appropriately combined.
