Description

The present invention relates to a portable terminal software version upgrade method and a portable terminal, which are required to be compact and lightweight, such as a Holter electrocardiograph.

Since the Holter electrocardiograph needs to be worn on the patient for a long time, the Holter electrocardiograph has been reduced in size and weight in order to reduce the burden on the patient. Such a small and lightweight Holter electrocardiograph is described in Patent Document 1, for example.

In this type of Holter electrocardiograph, generally, a software program for controlling measurement, recording, communication, etc. is upgraded via a memory card. Specifically, after inserting the memory card into an external PC and writing the upgrade data to the memory card, insert this memory card into the card slot of the Holter electrocardiograph and the software program of the internal memory of the Holter electrocardiograph. To upgrade. The operation of the version upgrade and whether the version upgrade was performed normally are performed by looking at the liquid crystal display of the Holter monitor.

JP, 2016-043068, A

In the Holter electrocardiograph as described above, the size of the main body of the device is almost determined by the size of the memory card, the size of the display unit, and the size of the battery.

Therefore, for the purpose of further reducing the size of the Holter electrocardiograph, the display unit is not configured by a liquid crystal screen but is configured only by an LED (Light Emitting Diode), or a card slot for inserting a memory card is abolished. For example, it is possible to record data in the internal memory. In such a case, it is conceivable that the Holter electrocardiograph and the external personal computer are connected by a USB cable, and the version upgrade data is written in the internal memory via the USB cable.

However, in such a case, an operation for setting the access right to the internal memory is required, and it is difficult to perform such an operation by button operation based only on the light emitting state of the LED. Further, it is difficult to judge the result of the version upgrade from the LED alone.

The present invention has been made in view of the above points, and a software version upgrade method for a mobile terminal, which can easily perform a software version upgrade even if there is no liquid crystal screen or only a small liquid crystal screen. , And a mobile terminal are provided.

One aspect of the software version upgrade method for a mobile terminal of the present invention is:

Writing the version upgrade file from the outside to the internal memory via the USB cable connected to the USB terminal unit by giving the USB controller exclusive access to the internal memory;
When it is detected that the USB cable is reinserted into the USB terminal unit after the USB cable is unplugged from the USB terminal unit in a state where the version upgrade file exists in the internal memory, the arithmetic control is performed. A section for giving exclusive access to the internal memory, and the arithmetic control section uses the bus power from the USB cable to perform a version upgrade based on the version upgrade file;
including.

One aspect of the mobile terminal of the present invention is
Internal memory,
A USB terminal to which a USB cable can be connected,
USB controller,
An arithmetic control unit,
A USB connection detector that detects whether or not the USB cable is connected to the USB connection terminal;
A mobile terminal having
When the USB controller is given the exclusive access right to the internal memory, the USB controller writes the version upgrade file from the outside to the internal memory via the USB cable connected to the USB terminal unit,
The operation control unit is configured such that, in a state where the version upgrade file exists in the internal memory, the USB cable is reinserted into the USB terminal unit after the USB cable is removed from the USB terminal unit. When detected by the connection detection unit, the exclusive access right to the internal memory is given, and the version upgrade based on the version upgrade file is performed using the bus power from the USB cable.

According to the present invention, since the access right is transferred from the USB controller to the CPU to perform the version upgrade by using the USB cable as a trigger, the software version can be obtained even if there is no liquid crystal screen or only a small liquid crystal screen. It can be done easily.

It is a figure which shows the external appearance structure of a Holter electrocardiograph, FIG. 2A is the perspective view which looked at the Holter electrocardiograph from the front side, and FIG. 2B is the perspective view which looked at the Holter electrocardiograph from the back side. Block diagram showing the configuration of the Holter monitor The figure which shows the procedure of the software version upgrade by embodiment. 6 is a flowchart showing a processing procedure of software version upgrade of the Holter electrocardiograph according to the embodiment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<Overall structure>
1 and 2 are diagrams for explaining the overall configuration of the Holter electrocardiograph 100 according to the embodiment. FIG. 1 is a diagram showing how the Holter electrocardiograph 100 is attached to an electrocardiogram sensor sheet 200, and FIG. 2 is a diagram showing an external configuration of the Holter electrocardiograph 100.

As shown in FIG. 1, the Holter electrocardiograph 100 is detachably attached to a sensor sheet 200 for measuring an electrocardiogram. The sensor sheet 200 is attached to the body of the subject (chest in the case of FIG. 1). The sensor sheet 200 is provided with electrodes 211, 212, 213 for measuring an electrocardiogram, and a connector 220 to which the Holter electrocardiograph 100 is attached. In the case of FIG. 1, three electrodes 211, 212, 213 are provided. Of the three electrodes 211, 212, 213, the electrodes 211, 212 are related electrodes, and the electrode 213 is an indifferent electrode. Is.

The connector 220 mechanically and electrically connects the sensor sheet 200 and the Holter electrocardiograph 100. The electrodes 211, 212, 213 and the connector 220 are electrically connected by wiring, and when the Holter electrocardiograph 100 is attached to the connector 220, the terminal of the connector 220 and the terminal of the Holter electrocardiograph 100 are connected. Are electrically connected, the Holter electrocardiograph 100 is electrically connected to the electrodes 211, 212, and 213. Further, the connector 220 has a shape capable of stably holding the Holter electrocardiograph 100 when the Holter electrocardiograph 100 is attached.

2A is a perspective view of the Holter electrocardiograph 100 viewed from the front side, and FIG. 2B is a perspective view of the Holter electrocardiograph 100 viewed from the back side. An event button 101, LED lamps 102a, 102b, 102c, etc. are provided on the front side of the Holter electrocardiograph 100. The event button 101 is a button that is pressed by the patient when the patient has a chest pain, for example, whereby the Holter electrocardiograph 100 is recorded as an event that the patient has some behavior or symptom. Among the LED lamps 102a, 102b, 102c, for example, the LED lamp 102a emits green light, the LED lamp 102b emits orange light, and the LED lamp 102c emits green light.

In the Holter electrocardiograph 100 of the present embodiment, the orange LED lamp 102b on the upper right emits light when the software version is being upgraded. This allows the user to recognize that the software version is being updated.

A record button 103 is provided on the side surface of the Holter electrocardiograph 100, and when the user operates the record button 103, the Holter electrocardiograph 100 starts measurement/recording of an electrocardiogram. Incidentally, even if the recording button 103 is not operated for 15 minutes after the power of the Holter electrocardiograph 100 is turned on, the recording of the electrocardiogram is automatically started. As a result, omission of recording due to forgetting to press the record button 103 is prevented. To end the recording, the recording button 103 and the event button 101 may be simultaneously pressed and held.

A connector 110 is provided on the back side of the Holter electrocardiograph 100. The connector 110 has an electrode terminal portion 111 and a USB terminal portion 112. The electrode terminal portion 111 and the USB terminal portion 112 are provided adjacent to each other, and a groove 113 into which the convex portion 221 of the connector 220 of the sensor sheet 200 is fitted is formed around the electrode terminal portion 111 and the USB terminal portion 112. As a result, when the Holter electrocardiograph 100 is attached to the sensor sheet 200, the protrusion 221 and the groove 113 are fitted to each other, so that the electrode terminal portion 111 and the USB terminal portion 112 are shielded from the outside. Accordingly, by attaching the Holter electrocardiograph 100 to the sensor sheet 200, both the electrode terminal portion 111 and the USB terminal portion 112 can be made waterproof at once.

FIG. 3 is a block diagram showing the configuration of the Holter electrocardiograph 100. The Holter electrocardiograph 100 includes a battery 121, an electrode terminal unit 111, a USB terminal unit 112, an electrode interface (I/F) 114, a USB I/F 115, a CPU 122 as a calculation control unit, a USB controller 123, and an internal memory. 124, a wireless unit 125, a USB connection detection unit 126, operation buttons (event button 101, record button 103), and an LED lamp 102.

As the battery 121, a small battery such as a button battery is used to reduce the size and weight of the Holter electrocardiograph 100.

The CPU 122 controls the entire operation of the Holter electrocardiograph 100 based on a software program stored in a built-in memory (FRAM (registered trademark)) 122a built in the CPU 122. The CPU 122 controls, for example, an operation of measuring an electrocardiogram, a light emitting operation of the LED lamp 102, and a wireless operation by the wireless unit 125 according to a software program.

When the USB cable is connected to the USB terminal unit 112, the USB controller (or USB driver) 123 may transfer data between the connected electronic device and the electronic device according to the USB standard, and use bus power. Electric power is supplied from the electronic device to the Holter electrocardiograph 100.

The internal memory 124 is a NAND flash type memory. As a result, it can be used as an alternative storage device for a memory card, and the Holter electrocardiograph 100 can be downsized. Further, the CPU 122 and the USB controller 123 can exclusively access the internal memory 124. Here, a configuration may be considered in which the CPU 122 accesses the internal memory 124 via the USB controller 123, but in the case of the present embodiment, the internal memory 124 can be accessed exclusively from both the CPU 122 and the USB controller 123. It has become. As a result, the power of the USB controller 123 can be turned off when the CPU 122 performs writing, so that power saving can be achieved. Note that which has the access right may be controlled by the CPU 122, for example.

The USB connection detection unit 126 detects whether or not an external electronic device is connected via the USB cable based on the voltage of the USB connection terminal unit 112. That is, when the voltage of the USB connection terminal unit 112 is equal to or higher than the predetermined threshold value, it is detected that an external electronic device is connected via the USB cable.

<Version up>
FIG. 4 is a diagram showing a procedure for software version upgrade according to the present embodiment. In addition, a square frame in the drawing indicates a device having an access right to the internal memory 124. For example, in FIG. 4A, since the personal computer 300 is surrounded by a frame, the personal computer 300 has the access right to the internal memory 124. On the other hand, in FIG. 4D, since the Holter electrocardiograph 100 is surrounded by a frame, the Holter electrocardiograph 100 has access to the internal memory 124.

First, as shown in FIG. 4A, the Holter electrocardiograph 100 and the personal computer 300 are connected by the USB cable 400. At this time, the personal computer 300 recognizes the internal memory 124 of the Holter electrocardiograph 100 as a USB memory. As shown in FIG. 4B, when the user operates the personal computer 300, the version-up file is copied from the personal computer 300 to the internal memory 124.

Next, as shown in FIG. 4C, the user disconnects the USB cable 400 from the Holter electrocardiograph 100 and/or the personal computer 300. This removal may be performed by both the Holter electrocardiograph 100 and the personal computer 300, or may be performed by either the Holter electrocardiograph 100 or the personal computer 300. The point is that the bus power is not supplied from the personal computer 300 to the Holter electrocardiograph 100, and the USB connection detection unit 126 can detect that the USB cable 400 has been removed.

Next, as shown in FIG. 4D, the user connects the Holter electrocardiograph 100 and the personal computer 300 again by the USB cable 400. At this time, the USB connection detection unit 126 of the Holter electrocardiograph 100 recognizes that the connection is made to the personal computer 300 via the USB cable 400. When the detection result indicating that the USB cable 400 is reconnected is obtained in this way, the CPU 122 transfers the access right to the internal memory 124 from the personal computer 300 (that is, from the USB controller 126) to itself, and the internal memory 124 is stored. Upgrade using the copied version upgrade file. Here, the version upgrade is a process of expanding the version upgrade file in the internal memory 124 into the internal memory 122a. The Holter electrocardiograph 100 performs this version upgrade by using the bus power supplied from the USB cable 400. During this version upgrade, the LED lamp 102c is turned on, which allows the user to recognize that the version upgrade is being performed.

When the version upgrade is completed, as shown in FIG. 4E, the access right to the internal memory 124 is transferred from the CPU 122 to the personal computer 300 (that is, the USB controller 123), and the personal computer 300 is recorded in the internal memory 124 by the CPU 122 during the upgrade. The checksum file regarding the version upgrade is read from the internal memory 124.

As a result, the user can confirm on the personal computer 300 whether the version upgrade has been normally performed by confirming the checksum on the personal computer 300. As a result, even if the Holter electrocardiograph 100 does not have a liquid crystal screen, the user can know the upgrade result in detail. Incidentally, if it is confirmed that the version upgrade has failed, the processes after FIG. 4B may be performed again.

FIG. 5 is a flowchart showing a processing procedure for software version upgrade of the Holter electrocardiograph 100 according to the present embodiment.

The Holter electrocardiograph 100 starts the processing procedure of FIG. 5 when a battery (battery 121) is inserted or connected to the personal computer 300 by the USB cable 400. At the start of this processing procedure, the CPU 122 has the control right (access right) to the internal memory 124.

The Holter electrocardiograph 100 first determines in step S101 whether or not the USB cable 400 is connected. Actually, the CPU 122 determines whether or not the USB cable 400 is connected based on the detection result of the USB connection detection unit 126 (whether or not power is supplied by bus power).

If the Holter electrocardiograph 100 determines that the USB cable 400 is not connected in step S101 (step S101; NO), the Holter electrocardiograph 100 is activated by the battery and proceeds to step S102. The Holter electrocardiograph 100 performs normal processing such as measurement and recording of an electrocardiogram in step S102.

The Holter electrocardiograph 100 is turned off when the battery is removed in step S103 (step S103; YES). Further, the Holter electrocardiograph 100 determines whether or not the USB cable 400 is connected in step S104, and when determining that the USB cable 400 is connected (step S104; YES), moves to step S105 and the internal memory 124. The control right (access right) to the USB controller 123 from the CPU 122. Subsequently, in step S106, the personal computer 300 connected by the USB cable 400 confirms the recording data and the like recorded in the internal memory 124 via the USB controller 123. The version upgrade file in the personal computer 300 can be copied to the internal memory 124 in step S105.

The Holter electrocardiograph 100 is turned off when the USB connection is disconnected in step S107 (step S107; YES) and the battery is removed in step S108 (step S108; YES).

On the other hand, when the Holter electrocardiograph 100 determines that the USB cable 400 is connected in step S109 (step S101; YES), the Holter electrocardiograph 100 is activated by the USB bus power and moves to step S109. The Holter electrocardiograph 100 determines whether or not there is a version upgrade file in the internal memory 124 in step S109.

If there is no version upgrade file in the internal memory 124 (step S109; NO), the process moves from step S109 to step S110, and the control right (access right) to the internal memory 124 is transferred from the CPU 122 to the USB controller 123. Then, in the subsequent step S111, the personal computer 300 is operated to copy the version upgrade file to the internal memory 124 via the USB controller 123. Incidentally, the personal computer 300 side controls which version-up file is written. When the USB connection is disconnected in the subsequent step S112, the power is turned off.

When the USB cable 400 is reconnected from this power-off state, the process is restarted, and the process proceeds to step S109 via step S101. Since the version upgrade file has been copied to the internal memory 124 in step S111 described above, it is determined that there is a version upgrade file in step S109 (step S109; YES), and the process proceeds to step S120.

In step S120, the CPU 122 accesses the version upgrade file stored in the internal memory 124 to perform the version upgrade process. In this way, when the USB cable 400 is once removed and then reconnected, the CPU 122 performs the version upgrade process.

In the following step S121, the CPU 122 creates a version upgrade result file (checksum file) and writes this in the internal memory 124. In the following step S122, the control right to the internal memory 124 is transferred from the CPU 122 to the USB controller 123. As a result, the version upgrade result file (checksum file) can be viewed from the personal computer 300. When the USB connection is disconnected in the subsequent step S123, the power is turned off.

As described above, the Holter electrocardiograph 100 of the present embodiment stores the version-up file in the internal memory 124 under the control of the USB controller 123, and then uses the USB cable 400 as a trigger to insert and remove the USB cable 400 into the internal memory 124. The access right is transferred to the CPU 122 (in the example of FIG. 5, the control right is transferred from the USB controller 123 to the CPU 122 when returning to the start of the flowchart from step S112), and the version is upgraded. As a result, the version can be easily upgraded even if the main body does not have a liquid crystal screen or an operation unit, so that the apparatus main body can be downsized.

Further, since the USB cable 400 is always connected at the time of version upgrade, the bus power from the USB cable 400 can be used to perform the version upgrade. As a result, conventionally, in order to prevent the version upgrade from being unsuccessfully executed due to a decrease in the battery voltage, a version-dedicated battery is inserted to perform the version upgrade. According to this, since a stable power supply can be secured by the bus power, it is not necessary to prepare a separate battery.

In addition, the software version upgrade method of the above-described embodiment can be executed by using a general-purpose mass storage class without using a dedicated USB driver, and therefore, there is an advantage that it is not necessary to use a dedicated USB driver.

In the above-described embodiment, the case where the other party to which the USB is reconnected is the personal computer 300 has been described, but the other party is not limited to the personal computer 300, and the point is that the Holter electrocardiograph 100 is bus-powered. Any device that can supply the That is, the device to be reconnected need not be the same device as the device that provided the version-up file (for example, the personal computer 300). For example, it may be a mobile battery. However, in consideration of checking the checksum in the subsequent processing, it is desirable that the device can display the checksum file.

In addition, the serial number of the device, the default setting value, etc. are transmitted from the personal computer 300 to the Holter electrocardiograph 100 via the USB cable 400 at the same timing as the version upgrade file copy and the version upgrade file. You may deploy it. Specifically, the serial number, the default setting value, and the like are copied to the internal memory 124 via the USB cable 400, and the serial number, the default setting value, and the like are transferred from the internal memory 124 to the CPU 122 when the USB cable 400 is reconnected. It is expanded in the built-in memory 122a. By doing so, even if there is no liquid crystal screen or only a small liquid crystal screen, the serial number, the default setting value, etc. can be easily developed in the Holter electrocardiograph 100.

Further, in the above-described embodiment, the case where the software version upgrade method according to the present invention is applied to the Holter electrocardiograph has been described, but the present invention can also be applied to mobile terminals other than the Holter electrocardiograph. The present invention is suitable for a small mobile terminal that does not have a liquid crystal screen.

The above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be limitedly interpreted by these. That is, the present invention can be implemented in various forms without departing from the gist or main features thereof.

The present invention is suitable, for example, as a software version upgrade method for a Holter electrocardiograph.
