  Here, the determination unit 36 will be described with reference to FIG. The determination unit 36 includes a temperature threshold storage unit 50 that stores a temperature threshold of the battery 30, and a temperature comparison that compares the temperature threshold stored in the temperature threshold storage unit 50 with the temperature of the battery 30 detected by the battery temperature detection unit 32.

  The temperature comparison unit 52 compares the temperature threshold value stored in the temperature threshold value storage unit 50 with the temperature of the battery 30 detected by the battery temperature detection unit 32, and if the temperature of the battery 30 is lower than the temperature threshold value, the comparison determination unit 58 Determines that the battery 30 is normal. When the temperature of the battery 30 is higher than the temperature threshold, the comparison determination unit 58 determines that the battery 30 is abnormal.

  The temperature threshold is set based on a temperature that promotes deterioration of the battery 30. A temperature threshold value can be arbitrarily set by the operation unit 44 and stored in the temperature threshold value storage unit 50. For example, the temperature threshold can be set to 50 ° C.

  The battery temperature detection unit 32 detects the temperature of the battery 30 at predetermined time intervals. The predetermined time interval is an interval of several seconds, for example, an interval of 5 seconds. Each time the temperature of the battery 30 is detected at a predetermined time interval in the battery temperature detection unit 32, the temperature comparison unit 52 detects the temperature threshold stored in the temperature threshold storage unit 50 and the battery detected by the battery temperature detection unit 32. 30 temperatures are compared at predetermined time intervals.

  The remaining amount comparison unit 56 compares the remaining amount threshold stored in the remaining amount threshold storage unit 54 with the remaining amount of the battery 30 detected by the battery remaining amount detection unit 34, and the remaining amount of the battery 30 is determined from the remaining amount threshold. If it is higher, the comparison / determination unit 58 determines that the battery 30 is normal. When the remaining amount of the battery 30 is lower than the remaining amount threshold value, the comparison determination unit 58 determines that the battery 30 is abnormal, that is, charging is necessary.

  The remaining amount threshold is set based on the remaining amount that requires charging of the battery 30. A remaining amount threshold value can be arbitrarily set by the operation unit 44 and stored in the remaining amount threshold value storage unit 54. For example, the remaining amount threshold can be set to 10%.

  The battery remaining amount detection unit 34 detects the remaining amount of the battery 30 at the same interval as a predetermined time interval for detecting the temperature of the battery 30. Each time the remaining amount of the battery 30 is detected at a predetermined time interval in the battery remaining amount detection unit 34, the remaining amount comparison unit 56 calculates the remaining amount threshold stored in the remaining amount threshold storage unit 54 and the remaining battery amount detection unit. The remaining amount of the battery 30 detected in 34 is compared at predetermined time intervals.

  That is, the temperature comparison unit 52 and the remaining amount comparison unit 56 compare the temperature and the remaining amount of the battery 30 at the same predetermined time interval. Then, the comparison / determination unit 58 simultaneously determines the state of the battery 30 at the predetermined time interval. Therefore, the state of the battery 30 can be determined without omission by each parameter of the battery 30.

  The warning information creation unit 38 creates warning information based on the determination result of the determination unit 36 (comparison determination unit 58). The warning information creation unit 38 displays a message on the image display unit 26 when the remaining amount of the battery 30 is insufficient or the battery 30 is hot, or displays a message prompting the battery 30 to charge the image display unit 26. Display.

  Based on the determination result of the determination unit 36 (comparison determination unit 58), the image composition unit 24 displays the image display unit when the temperature of the battery 30 is higher than the temperature threshold or when the remaining amount of the battery 30 is lower than the remaining threshold. The tomographic image displayed in 26 can also be frozen. Further, based on the determination result of the determination unit 36 (comparison determination unit 58), when the temperature of the battery 30 is higher than the temperature threshold, or when the remaining amount of the battery 30 is lower than the remaining amount threshold, the ultrasonic transmission / reception control unit 18 It can also be controlled not to transmit / receive ultrasonic waves.

  That is, based on the determination result of the determination unit 36 (comparison determination unit 58), the portable ultrasonic diagnostic apparatus can be switched to the power saving mode. Therefore, warning information that is a message when the remaining amount of the battery 30 is insufficient or when the battery 30 is high can be displayed on the image display unit 26, and the usage time of the portable ultrasonic diagnostic apparatus can be extended.

  Here, a specific example of the operation of the determination unit 36 will be described with reference to FIG. FIG. 4 (a) is a graph relating to the temperature of the battery 30. FIG. FIG. 4B is a graph relating to the remaining amount of the battery 30. The left end of each graph is the use start time of the portable ultrasonic diagnostic apparatus, and the battery 30 is the use start time. FIG. 4 (a) and FIG. 4 (b) are shown on the same time axis.

  The temperature A shown in FIG. 4 (a) is the temperature threshold value of the battery 30 stored in the temperature threshold value storage unit 50. The remaining amount B shown in FIG. 4 (b) is the remaining amount threshold of the battery 30 stored in the remaining amount threshold storage unit 54.

  The battery temperature detection unit 32 detects the temperature of the battery 30 at predetermined time intervals, and the battery remaining amount detection unit 34 detects the remaining amount of the battery 30 at predetermined time intervals. The solid line in the graph shown in FIG. The solid line in the graph shown in FIG. 4 (b) is the remaining amount of battery 30.

  As the time used by the battery 30 elapses, the temperature of the battery 30 increases and the remaining amount of the battery 30 decreases. The temperature comparison unit 52 compares the temperature A, which is the temperature threshold stored in the temperature threshold storage unit 50, with the temperature of the battery 30 detected by the battery temperature detection unit 32. The remaining amount comparison unit 56 compares the remaining amount B, which is the remaining amount threshold stored in the remaining amount threshold storage unit 54, with the remaining amount of the battery 30 detected by the battery remaining amount detecting unit 34 at predetermined time intervals.

  At time (T1), the temperature of the battery 30 reaches the temperature A which is the temperature threshold of the battery 30. When the temperature of the battery 30 is higher than the temperature A that is the temperature threshold, the comparison determination unit 58 determines that the battery 30 is abnormal.

  The warning information creation unit 38 creates warning information based on the determination result of the determination unit 36 (comparison determination unit 58). The warning information creation unit 38 creates a warning message that the battery 30 is hot. Specifically, as shown in FIG. 5, the warning information creation unit 38 creates a message 60 such as “The battery temperature is high” or “The power will turn off after a while”, and the image display unit 26 To display. In addition, the warning information creation unit 38 creates a caution mark 64 that alerts the operator and displays it on the image display unit 26. The attention mark 64 is displayed so as to be superimposed on the remaining amount mark 62 indicating the remaining amount of the battery 30.

  When the adapter connection detection unit 42 detects that the AC adapter 40 is connected to the outlet and the AC adapter 40 supplies power to each component or the battery 30 is charged, the determination unit 36 The (comparison determination unit 58) determines that the adapter is connected, and the warning information creation unit 38 does not create the warning information as described above. In other words, even when the temperature of the battery 30 is higher than the temperature threshold or when the remaining amount of the battery 30 is lower than the remaining threshold, the adapter connection by the AC adapter 40 is preferentially determined by the determination unit 36 (comparison determination unit 58). Is determined by When the adapter is connected by the AC adapter 40, warning information is not created.

  Here, the operation of the determination unit 36 will be described using a specific example with reference to FIG. FIG. 6 is a graph showing a state where time has further elapsed from the specific example of FIG.

  At time (T1), the temperature of the battery 30 reaches the temperature A which is the temperature threshold of the battery 30. When the temperature of the battery 30 is higher than the temperature A that is the temperature threshold, the comparison determination unit 58 determines that the battery 30 is abnormal. Furthermore, as the time for which the battery 30 is used elapses, the temperature of the battery 30 increases and the remaining amount of the battery 30 decreases. At time (T2), the remaining amount of the battery 30 reaches the remaining amount B that is the remaining amount threshold of the battery 30. When the remaining amount of the battery 30 is lower than the remaining amount B that is the remaining amount threshold, the comparison determination unit 58 determines that the battery 30 is further abnormal.

  The warning information creation unit 38 creates warning information based on the determination result of the determination unit 36 (comparison determination unit 58). The warning information creation unit 38 is based on the fact that the temperature of the battery 30 is higher than the temperature A, which is a temperature threshold, and the remaining amount of the battery 30 is lower than the remaining amount B, which is a remaining amount threshold. Create a warning message that the battery 30 is hot and a warning that the battery 30 is low.

  The warning information shown in FIG. 6 is higher than the warning level shown in FIG. 4 because the temperature of the battery 30 is higher than the temperature A that is the temperature threshold and the remaining amount of the battery 30 is lower than the remaining amount B that is the remaining threshold. Will also raise the warning level. For example, the warning information creating unit 38 creates a message 60 such as “The power will be turned off soon” and displays the message 60 on the image display unit 26.

  Note that the battery remaining amount detection unit 34 detects the remaining amount of the battery 30, but the remaining amount of the battery 30 may not be detected due to a failure of the battery 30. In that case, when the remaining amount of the battery 30 cannot be detected, the warning information creation unit 38 creates warning information indicating that the battery 30 is out of order and displays the warning information on the image display unit 26. Warning information indicating that the battery 30 has failed is displayed on the image display unit 26 in preference to other images.

  Specifically, as shown in FIG. 7, the warning information creation unit 38, for example, “There is a possibility that the battery has failed.” “The power will turn off soon.” “Contact your service representative. And the like are displayed on the image display unit 26. The message 70 displayed on the image display unit 26 is displayed so as to overlap the ultrasonic image. In addition, the warning information creation unit 38 creates a battery failure mark 72 that prompts the operator to pay attention to the failure of the battery 30, and causes the image display unit 26 to display the battery failure mark 72. The battery failure mark 72 is displayed superimposed on the remaining amount mark 62 indicating the remaining amount of the battery 30.

  As described above, according to the present embodiment, the battery temperature detection unit 32 that detects the temperature of the battery 30, the battery remaining amount detection unit 34 that detects the remaining amount of the battery 30, the temperature of the battery 30 and the remaining amount of the battery 30 are determined. Based on the determination unit 36 that determines the state of the battery 30 based on the determination, the warning information generation unit 38 that generates warning information based on the determination of the determination unit 36. Accordingly, the warning information can be appropriately displayed by monitoring parameters other than the remaining amount of the battery 30.

  Here, Example 2 will be described with reference to FIGS. The difference from the first embodiment is that the determination unit 36 determines the remaining usage time of the battery 30 up to the temperature threshold and the remaining amount threshold based on the temperature and the remaining amount of the battery 30.

  As shown in FIG. 8, the determination unit 36 includes a temperature threshold storage unit 50 that stores a temperature threshold of the battery 30, a temperature threshold stored in the temperature threshold storage unit 50, and the battery 30 detected by the battery temperature detection unit 32. A remaining temperature stored in the remaining amount threshold storage unit 54, a remaining amount threshold storage unit 54 that stores a remaining amount threshold of the battery 30, and a remaining amount stored in the remaining amount threshold storage unit 54. The remaining amount usage time estimation unit 82 that calculates the remaining usage estimated time based on the amount threshold and the remaining amount of battery 30 detected by the battery remaining amount detection unit 34, the temperature usage time estimation unit 80, and the remaining amount usage time Based on the estimated remaining usage time of the estimation unit 82, the usage time determination unit 84 determines the remaining usage time of the battery 30.

  The operation of the determination unit 36 will be described using a specific example with reference to FIG. Similar to the specific example shown in FIG. 4, as the time for which the battery 30 is used elapses, the temperature of the battery 30 increases and the remaining amount of the battery 30 decreases.

  Here, the current time is defined as time (T3). At time (T3), the temperature usage time estimation unit 80 calculates the remaining usage estimation time based on the temperature threshold value stored in the temperature threshold value storage unit 50 and the temperature course of the battery 30 detected by the battery temperature detection unit 32. To do. Specifically, the temperature usage time estimation unit 80 first uses the specific model function assumed from the relationship between the temperature measured until the time (T3) and the time to calculate the temperature progress after the time (T3). presume. For example, a particular model function is determined by minimizing measured temperature and time differences and variances by least squares. By extending a specific model function, the temperature course after time (T3) can be estimated.

  Then, the estimated use time to reach the temperature A, which is the temperature threshold stored in the temperature threshold storage unit 50, is estimated based on the temperature elapsed from the time (T3). Here, the use estimated time based on temperature is from time (T3) to time (T4).

  Further, in time (T3), the remaining capacity usage time estimation unit 82 is based on the remaining amount threshold stored in the remaining amount threshold storage unit 54 and the remaining amount of battery 30 detected by the remaining battery level detection unit 34. Calculate the remaining estimated usage time. Since the remaining usage estimated time calculation method is the same as that of the above-described temperature course, description thereof is omitted here.

  Then, the estimated use time to reach the remaining amount B, which is the remaining amount threshold stored in the remaining amount threshold storage unit 54, is estimated based on the remaining amount after the time (T3). Here, the estimated use time based on the remaining amount is from time (T3) to time (T5).

  The usage time determination unit 84 determines the remaining usage time of the battery 30 based on the remaining usage estimation time of the temperature usage time estimation unit 80 and the remaining usage time estimation unit 82. Specifically, the estimated usage time based on the temperature and the estimated usage time based on the remaining amount are compared, and the short estimated usage time is set as the remaining usage time of the battery 30. Here, the estimated usage time based on the temperature from time (T3) to time (T4) is the remaining usage time of the battery 30.

  The warning information creation unit 38 displays the remaining usage time of the battery 30 on the image display unit 26. Specifically, as shown in FIG. 10, the warning information creation unit 38 creates a message 90 indicating the remaining usage time such as “It can be used until time (T4).” Display on 26. Since the message 90 indicating the remaining usage time is relatively light information, the message 90 is displayed so as not to overlap the ultrasonic image displayed on the image display unit 26.

  As described above, according to the present embodiment, it is possible to monitor parameters other than the remaining amount of the battery and appropriately display the warning information indicating the remaining usage time.

  Here, Example 3 will be described with reference to FIG. The difference from the first and second embodiments is that the determination unit 36 determines the remaining usage time of the battery 30 based on the remaining amount of the battery 30 and the number of times of charging.

  The determination unit 36 includes the temperature threshold storage unit 50, the temperature usage time estimation unit 80, the remaining amount threshold storage unit 54, the remaining usage time estimation unit 82, the usage time determination unit 84, and the like shown in the second embodiment. A charge count measuring unit 86 that measures the number of times the battery 30 is charged is included.

  In the time (T3), the remaining capacity usage time estimation unit 82 includes a remaining amount threshold stored in the remaining amount threshold storage unit 54, a remaining amount of the battery 30 detected by the remaining battery level detection unit 34, and a charge count measuring unit 86. The remaining estimated usage time is calculated based on the number of times of charging of the battery 30 measured in step (1).

  The remaining usage time estimation unit 82 stores in advance the relationship between the number of times the battery 30 is charged and the remaining amount of the battery 30 (the slope of the remaining amount graph). For example, if the number of times the battery 30 is charged is 1 to 100 times, the slope of the graph of the remaining amount of the battery 30 as shown in FIG. If the number of times the battery 30 is charged is 101 to 200 times, the slope becomes steep by several degrees from the slope of the remaining battery 30 graph as shown in FIG. If the number of charging times of the battery 30 is 201 to 300 times, the inclination becomes steep by several degrees more than the inclination of the graph of the remaining amount of charging of the battery 30 of 101 to 200 times.

In addition, the number of times of charging the battery 30 is “n”, and the slope “a” of the remaining battery 30 graph can be obtained by the following equation.
{Expression} a = k × n (k: arbitrary coefficient)
Note that “k”, which is an arbitrary coefficient, may be a coefficient that gradually decreases as compared to an increase in “n”.

  Then, the remaining amount threshold stored in the remaining amount threshold storage unit 54 by the remaining amount of time after the time (T3) determined by the remaining amount of the battery 30 and the number of times of charging detected by the battery remaining amount detecting unit 34 Estimate the estimated usage time to reach the remaining amount B.

  Then, the usage time determination unit 84 determines the remaining usage time of the battery 30 based on the remaining usage estimation time of the temperature usage time estimation unit 80 and the remaining usage time estimation unit 82. Specifically, the estimated usage time based on the temperature and the estimated usage time based on the remaining amount are compared, and the short estimated usage time is set as the remaining usage time of the battery 30. Then, the warning information creation unit 38 displays the remaining usage time of the battery 30 on the image display unit 26.

  As described above, according to this embodiment, the number of times of charging other than the remaining amount of the battery can be monitored, and warning information indicating the remaining usage time can be appropriately displayed.
