2. Description of the Related Art In recent years, in mobile communication systems, the price of terminal devices and telephone charges have been reduced due to market liberalization and competition among a plurality of communication companies, and various types of communication services have been provided. At the same time, not only young people but also various generations of subscribers are increasing rapidly.

[0003] In addition, most of such terminal devices are not portable or portable, but portable.
In addition, the driving power is integrated with the main body and is supplied by a detachable battery. FIG. 11 is a diagram illustrating a configuration example of a terminal device to which driving power is supplied by a battery.

In FIG. 1, a feed point of an antenna 41 is connected to an antenna terminal of a transmitting / receiving section 42,
The modulation input and the demodulation output of
Are connected to the corresponding demodulation output and modulation input. TDM
A microphone 44 and a speaker 45 are connected to the modulation input and the demodulation output of the A control unit 43, respectively. The bus terminals of the transmission / reception unit 42 and the TDMA control unit 43 are connected to the bus 48 together with the control unit 46 and the display operation unit 47. The cathode of the battery 49 is grounded.
Is connected to the input of the voltage control unit 50 and the input of the A / D converter 51. The output of the A / D converter 51 is supplied to the control unit 46.
Connected to the corresponding input of The output of the voltage control unit 50 is transmitted to the transmission / reception unit 42, the TDMA control unit 43,
It is connected to a power supply line (not shown) serving as a supply path of driving power to the control unit 46, the display control unit 47, the A / D converter 51 and others.

The control unit 46 includes a processor 52 having an input port connected to the output of the A / D converter 51, a main memory 53 and a timer 54 connected to the bus 48 together with the processor 52. Consists of

In the terminal device having such a configuration, the voltage control unit 50 converts the power supplied by the battery 49 into DC power of a predetermined voltage, and supplies the DC power to each unit as drive power. In a specific storage area of the main memory 53, software for realizing functions to be provided as terminal devices based on a storage program control method (storage logic method) is stored in advance.
2 based on the procedure of processing performed in the process of executing the software, the transmitting / receiving unit 42 and the TDMA control unit 4 described above.
3. It is achieved by controlling the operations of the clock unit 54 and the display operation unit 47.

The channel control and other functions and processing procedures to be included as such software are not the features of the present invention and can be realized by applying various known techniques. here,
The description is omitted. On the other hand, the A / D converter 51 generates a monitor signal indicating the terminal voltage (electromotive force) of the battery 49 as a word having a predetermined word length, and supplies the monitor signal to the processor 52.

[0008] The processor 52 monitors the terminal voltage given as the monitor signal at a predetermined frequency, and the range of the terminal voltage is divided into a plurality (here, it is assumed to be "3" for simplicity). The remaining amount of the battery 49 is indirectly displayed on the display operation unit 47 as a range of values obtained by the operation. Hereinafter, such display of the remaining amount of the battery 49 is simply referred to as a “battery mark”.

Therefore, the operator can grasp the outline of the remaining amount of the battery by looking at the battery mark.

[0010]

However, the battery 49
The maximum value of the “number of charge / discharge cycles” is generally about several hundreds, regardless of the configuration of the battery 49.

That is, for a battery that has been charged many times, the shortage of the remaining amount indicated by the “battery mark” is sufficiently replenished even if the battery is charged for a long time. Even if the power consumption does not increase significantly, the remaining amount rapidly decreases in a very short time. Therefore, there is a possibility that an important call is unnecessarily interrupted, or the call quality is deteriorated, and the service quality is lowered.

It is to be noted that the battery 49 increases as the number of times of charging increases.
Prediction or detection of deterioration (effective decrease of remaining amount)
This can be realized by installing dedicated hardware. However, such hardware has been difficult to be actually mounted on an electronic device such as a portable terminal device in which reduction in power consumption is strictly required along with reduction in weight and size.

The present invention provides an electronic device and a power consumption measurement support device that can notify an operator of the deterioration of a battery or the degree of the deterioration without significantly increasing the scale of hardware. And

As shown by a dotted line, a set of a plurality of records is associated with the terminal voltage of the battery 49 in descending order and includes the following fields in addition to the above-described “threshold voltage” field and “standard charge amount” field. And these "threshold voltage" fields and "standard charge"
The point is that a value described later is stored in the field.

A value that is paired with the value registered in the “threshold voltage” field of the common record, a value larger than that value is registered in advance, and the remaining amount of the battery 49 in the descending order of the terminal voltage of the battery 49 The “upper limit voltage” field defining the “remaining amount category” in which the range is indirectly divided is stored in advance in the “threshold voltage” field with the minimum value of the terminal voltage of the battery 49 in the corresponding “remaining amount category”. You.

In the “standard charge amount” field, the minimum value of the amount of power to be supplied by the battery 49 in the corresponding “remaining amount category” is stored in advance. Hereinafter, the operation of the present embodiment will be described with reference to FIGS.
First, an initialization process and a procedure of a process performed after the initialization process is completed are the same as those of the above-described first embodiment except for the following points. Is omitted.

After completing the above-described initialization processing, the processor 52 acquires the terminal voltage V of the battery 49 via the A / D converter 51 at a predetermined frequency (FIG. 5A). Further, the processor 52 stores the battery unique value table 31
Among the records of BF-1, the record in which the terminal voltage thus obtained is equal to or less than the value of the “upper limit voltage” field and equal to or more than the value of the “threshold voltage” field (hereinafter, referred to as “current record”). ) (Fig. 5)
(b)).

The processor 52 sets the value of the “threshold voltage” field and the value of the “standard charge amount” field of the “current record” in the records of the battery specific value table 31BF-1 to the lower limit value described above. It is applied as VL and value PL (FIG. 5 (c)). That is, the battery 4
9 or the degree of the deterioration is determined by the battery 49
In the process of decreasing the remaining amount, the determination is made for each of the plurality of “remaining amount categories” described above, and the operator is appropriately notified via the display operation unit 47.

Therefore, prior to the time when the remaining capacity of the battery 49 becomes almost empty, the operator is properly notified that the battery 49 should be replaced, and the time required for obtaining and preparing a new battery is provided. Can be secured. Hereinafter, a third embodiment of the present invention will be described. The difference between the present embodiment and the above-described second embodiment is that, as shown by the broken line in FIG. 8, the battery specific value table 31BF-1 is replaced with the battery specific value table 31BF-1 which differs in the following points. The difference lies in the provision of the table 31BF-2 and the procedure of the following processing performed by the processor 52.

The battery specific value table 31BF-2
The differences between the configuration of the battery and the battery specific value table 31BF-1 are as follows. The number of times of charging performed on the battery 49 or a plurality of values of the number of times (here, for simplicity,
Assume "10". ) (For example, 1 to 5 times of “Category 1”, 6 to 10 times of “Category 2”), and occurs in the battery 49 in these “Charge number of times”. A “standard charge amount” field is formed as a plurality of fields in which standard charge amounts obtained based on a general tendency of deterioration are registered in advance.

In the following, among the plurality of “standard charge amounts” fields, the “standard charge amount” field to be actually referred to by the processor 52 will be described.
It is simply referred to as a “specific standard charge amount” field. Further, in the following, each “charging number classification” uses, as an identifier, a value of an integer part obtained by dividing the number of chargings actually performed on the battery 49 by a predetermined constant (for example, “50”). Assume that

The operation of this embodiment will be described below with reference to FIGS. 4 to 6 and FIG. The processor 52 detects that the "battery 49 has been replaced" by an operation of the operator's operation display unit 47 (an input operation performed by the operator when the battery 49 is replaced) (FIG. 5A).

Further, the processor 52 executes A at a predetermined frequency.
The terminal voltage of the battery 49 supplied via the / D converter 51 is monitored, and it is determined whether or not the terminal voltage is equal to 0 volt with a predetermined accuracy (FIG. 5B). Further, when the processor 52 has a “charging number counter” indicating the number of times of charging actually performed on the battery 49 in a specific storage area of the main memory 31 and detects that the battery 49 has been replaced. Alternatively, when the result of the determination is true, the value of the “charging number counter” is initialized to “0” (FIG. 5C).

The ID of the battery 49 may be stored (stored in a memory or the like) in the battery 49, and the replacement of the battery 49 may be detected by the processor 52 detecting a change in the ID. The processor 52 determines in advance that the value of the terminal voltage of the battery 49 that can be considered to have been charged to the battery 49 is given as the threshold value Vc, and every time the monitored terminal voltage increases to a value equal to or higher than the threshold value Vc as described above. Then, the value of the "charging number counter" is incremented (FIG. 5D). Further, the value of the “charging number counter” may be incremented each time the battery 49 is charged.

By the way, the processor 52 specifies the “current record” to be referred to in the battery specific value table 31BF-2 in the same manner as in the above-described second embodiment. Further, when referring to the “standard charge amount” from the “current record”, the processor 52 performs a process based on the following procedure to refer to the first to tenth fields described above. The “specific standard charge amount” field in which the “standard charge amount” is stored (that is, a field corresponding to the stored charge count or charge count category) is specified.

The value of the “charging counter” is set to “50”
The value of the integer part of the value obtained by dividing by (however, if it exceeds "10", it is regarded as "9")
Is determined as the above-mentioned identifier. A single field corresponding to the identifier among the above-described first to tenth fields of the “current record” is referred to as a “target standard charge amount”.

That is, the standard charge amount to be applied as a criterion for determining whether or not the battery 49 has deteriorated is obtained as a value flexibly adapted to the degree of deterioration of the battery 49 in accordance with the number of times of charging. . Therefore, according to the present embodiment, the deterioration of the battery 49 is detected more accurately than in the first and second embodiments described above.

In the present invention, for example, the display operation unit 4
The value of the “charging number counter” may be appropriately incremented according to a message given via the communication port 7 or a communication port. Hereinafter, a fourth embodiment of the present invention will be described. The difference between the present embodiment and the above-described first to third embodiments is that, as shown by the dashed line in FIG. 8, the battery unique value tables 31BF, 31BF-1, 31B are as follows.
Battery unique value tables 31BF, 31B different from F-2
Battery specific value table 31 instead of F-1 and 31BF-2
The BF-3 is provided, and the procedure of the following processing performed by the processor 52 is as follows.

The battery specific value table 31BF-3
And battery specific value tables 31BF, 31BF-1, 31
The difference between the BF-2 and the BF-2 is as follows. -It is constituted by a plurality of areas having different characteristics and corresponding to a unique battery identifier assigned to each battery that can be mounted as the battery 49. -For each battery having different characteristics, the above-mentioned "upper limit voltage" field, "threshold voltage" field, "standard power amount" field (first to tenth fields are given in advance based on actual measurement and the like). May be classified.) Is stored in advance.

In the following, an area to be actually referred to by the processor 52 among the plurality of areas described above is simply referred to as a “specific area”. Hereinafter, the operation of the present embodiment will be described with reference to FIG. The processor 52 acquires a battery identifier indicating the newly installed battery 49 as a message given via the operation display unit 47, and stores the battery identifier in a predetermined register arranged in the main memory 31.

When referring to the battery unique value table 31BF-3, the processor 52 acquires the battery identifier stored in the above-described register, and among the plurality of areas of the battery unique value table 31BF-3,
The area corresponding to the battery identifier is determined as the “specific area” described above. Further, the processor 52 specifies the “current record” to be referred to in the same manner as in the above-described first to third embodiments, and appropriately refers to a desired field constituting the “current record”.

The procedure of the processing performed by the processor 52 while referring to such a “current record” is the same as that in the first to third embodiments described above, and the description thereof is omitted here. I do. That is, even if the characteristics of the battery that can be mounted are various, as long as a value that is suitable for the actually mounted battery is stored in advance in the corresponding area of the battery specific value table 31BF-3, Is detected with high accuracy.

It is to be noted that the “upper limit voltage” field, the “threshold voltage field”, and the “standard power amount” field specific to the battery may be stored in the memory in the battery 49, and the processor 52 may obtain and use these fields. Hereinafter, a fifth embodiment of the present invention will be described. The difference between the present embodiment and the above-described first to fourth embodiments is that the following components are added to the terminal device shown by a dashed line in FIG. 32 is at the connected point.

A switch 33 connected to the inputs of the voltage control circuit 50 and the A / D converter 51 and to the anode terminal of the battery 49; a make contact of the switch 33; A plug seat 34 in which a first pin and a second pin are connected to a specific input port, respectively. The power measurement adapter 32 includes the following components.

A power supply circuit 35 for outputting driving power; a cascade connection to the power supply circuit 35 and a corresponding plug (not shown) to be connected to the first pin of the plug seat 34 described above. A power measuring unit 35 having a first output directly connected to a pin; cascaded to a second output of the power measuring unit 35;
And a terminal interface section 36 having an output directly connected to a corresponding pin of a plug (not shown) to be connected to the second pin of the plug seat 34 described above. FIG. 10 shows a fifth embodiment of the present invention. It is an operation | movement flowchart of a form.

Hereinafter, the operation of the present embodiment will be described with reference to FIGS. 4 to 6 and FIG. The feature of the present embodiment lies in the procedure of the following processing performed by the processor 52. The power measurement adapter 32 is connected to the terminal device via the above-described plug seat 34 at the time of adjustment and operation confirmation performed prior to shipment, repair, and recovery test. In the mode in which the power measurement adapter 32 is connected in this manner, the common contact of the switch 33 is connected between the switch 33 and the make contact instead of the break contact according to the force physically given by the housing of the power measurement adapter 32. A drive power supply path is formed.

In the power measuring adapter 32, the power supply circuit 35
Outputs the drive power to be supplied to the terminal device in place of the battery 49. This drive power is supplied to the power measurement unit 35
And supplied to the terminal device via the plug seat 34. The power measurement unit 35 measures the power supplied to the terminal device in this manner (here, for simplicity, it is assumed that the value is only the current), and the terminal interface unit 36 processes the measurement result with a processor. 52 is notified at a predetermined frequency.

On the other hand, the processor 52 performs a predetermined process based on the same procedure as in the conventional example, and for each mode identified in the process, averages the current values notified by the terminal interface unit 36. Is calculated (FIG. 10 (1)),
The average value is referred to as the “current” in the current table 31CT.
It is stored in the field (FIG. 10 (2)). Here,
For simplicity, in the storage area of the current table 31CT,
It is assumed that the storage area of the “current” field is configured as a readable and writable nonvolatile storage area.

That is, in the current table 31CT, the value of the current consumption, which accurately indicates the power actually consumed by the terminal device in each mode, is stored without greatly increasing the scale of the hardware of the terminal device. Therefore, according to the present embodiment, even when the characteristics of the components of the terminal device have a large deviation, the accuracy of the integrated value of the power consumption calculated by the processor 52 based on the above-described processing procedure is high. This is maintained, and the accuracy of detection of deterioration of the battery 49 is also increased.

In this embodiment, the contacts of the switch 33 are switched according to the force physically applied by the housing of the power measurement adapter 32. However, such a contact point of the switch 33 may be manually switched according to an operation performed by an operator who performs the above-described adjustment and operation check. Hereinafter, the operation of the sixth embodiment of the present invention will be described with reference to FIGS.

The difference between this embodiment and the above-described fifth embodiment lies in the following processing procedure performed by the processor 52. The processor 52 executes the program stored in the main memory 31 in advance when the power measurement adapter 32 is connected via the plug seat 34 at the time of the above-described adjustment and operation check.

In the process of executing such a program, the processor 52 stores the value of the “mode identifier” field in the current table 31CT based on a procedure different from a normal calculation procedure (for example, a channel control procedure or the like). The operating states of the transmitting / receiving unit 42, the TDMA control unit 43, and the like are sequentially and promptly set to a state that can be regarded as a mode corresponding to all “mode identifiers” that can be stored.

Further, in each of these modes, the processor 52 calculates the average value of the current value notified by the terminal interface unit 36 and calculates the average value in the same manner as in the fifth embodiment. Is stored in the corresponding “current” field of the current table 31CT. That is, of the records of the current table 31CT, the values of the desired accuracy are stored in the “current” field of all the valid records more quickly than in the fifth embodiment.

Therefore, according to this embodiment, shipping,
The efficiency of adjustment and operation confirmation to be performed prior to repair and recovery tests is greatly increased. In the present embodiment, there is no disclosure of an event that gives a point in time when the processor 52 should start the processing shown in FIGS. 5 and 10 (hereinafter, referred to as “non-normal processing”).
