Moreover, the data for accumulation | storage are produced | generated based on the 2nd production | generation rule which acquires the various biological data produced | generated by A / D conversion from a main | base station.

<Configuration>
FIG. 1 is a diagram showing an example of functional blocks of the biometric data transmitter of this embodiment. As shown in this figure, the “biological data transmitter” 0100 of the present embodiment includes a “biological signal detector” 0101, a “first data generator” 0102, a “first data transmitter” 0103, “Second data generation unit” 0104, “Second data storage unit” 0105, “Second data transmission unit” 0106, “First data generation rule acquisition holding unit” 0107, “Second data generation rule acquisition” And a “biological data transmission command receiving unit” 0109. Each configuration will be described below. The function of each component described below can be realized by executing a predetermined program in a processor such as an MPU, or can be realized by an analog circuit that executes a specific process. It is.

  The “biological data transmitter” has a function for transmitting biological data to the parent device. Here, the biological data is data obtained from a living body through a sensor. For example, an electrocardiographic waveform (a waveform indicating the state of electrical activity of the heart), a temperature on or near the body surface, body Data such as movement, sweating volume, pulse, height, weight, body fat percentage, cholesterol level, blood pressure, blood glucose level, etc. can be considered. The master unit that has received the biometric data from the biometric data transmitting slave unit processes these data (details will be described in the second embodiment).

  The “biological signal detection unit” has a function of detecting a plurality of types of biological signals including the electrocardiographic waveform of the living body. Here, detecting a biological signal means detecting a signal obtained from a living body. As means for detecting a signal of an electrocardiographic waveform of a living body, for example, an electrocardiogram sensor (Electrocardiogram) may be used. In addition, it is conceivable to use a sensor that detects each biological data, such as a temperature sensor as a means for detecting the temperature on or near the body surface, and an acceleration sensor as a means for detecting the movement of the body. That is, the biological signal detection unit is realized by an assembly of these sensors.

  The “first data generation unit” has a function of generating first data by performing A / D conversion for each detected biological signal. The first data is generated based on a first data generation rule described below. That is, each biological signal that is analog data is converted into digital data based on the first data generation rule. Note that each biological signal means each type of biological signal, and X-direction acceleration, Y-direction acceleration, and Z-direction acceleration obtained from one acceleration sensor are also handled as separate biological signals.

  As a means for A / D converting a plurality of biological signals, it is possible to sequentially perform the A / D conversion of each biological signal by using a single A / D conversion circuit with a time shift (time division processing). It is also possible to perform A / D conversion of two or more biological signals in parallel using a plurality of A / D conversion circuits. Even when there are a plurality of A / D conversion circuits, a single A / D conversion circuit may be configured to A / D convert a plurality of biological signals. In this case, another A / D conversion circuit may be used when one A / D conversion circuit becomes malfunctioning.

  When performing A / D conversion of a plurality of biological signals, it is possible to change the sampling frequency for each biological signal. For example, data is sampled at a cycle of 1024 Hz for an electrocardiogram signal, data is sampled at a frequency of 4 Hz for a temperature signal, and data is sampled at a cycle of 256 Hz for an acceleration signal.

  In addition, when A / D conversion of a plurality of biological signals is performed, the number of quantization bits can be changed for each biological signal. Even when a plurality of biological signals are A / D converted using a single A / D conversion circuit, the number of quantization bits is changed by changing the register setting of the A / D conversion circuit for each biological signal. It is conceivable to reduce the number of bits by performing subsequent software processing. For example, an ECG waveform signal is quantized with 10 bits, and a temperature signal is quantized with 8 bits.

    The “first data transmission unit” has a function of immediately transmitting the generated first data. Here, transmitting the generated first data immediately means transmitting the generated data at real time or near real time. In addition, the first data is compressed and transmitted, or encrypted and transmitted.

  The function of the first data transmission unit is realized by, for example, a processor, a communication interface, and a processing program stored in the ROM. As the communication interface, a wireless system or a wired system can be used. Specifically, for wireless communication, it is conceivable to use a frequency in the 950 MHz band. Although the frequency depends on the environment, since the frequency has a communication range of about 30 m, it is possible to transmit wireless data to the parent device arranged in the range. As wired communication, it is conceivable to connect to a parent device by serial communication I / F (USB I / F or the like) and transmit data by serial communication.

  The “second data generation unit” has a function of generating second data for accumulation from the generated first data. The function of the second data generation unit is realized by, for example, a processing program stored in a processor, RAM, or ROM. Here, as the second data for storage, data obtained by blocking the first data in a predetermined unit, data obtained by compressing the first data, data obtained by encrypting the first data, and the like can be considered. The process of generating the second data for accumulation from the first data is performed according to a predetermined generation rule described below.

  FIG. 2 is a diagram illustrating an example of the content of the second data generated by the second data generation unit. In the example of this figure, the first data obtained from the detection start time (data transmission start command) to the detection end time (data transmission stop command) of a plurality of types of biological data at an arbitrary date and time is regarded as one block, Data in which information such as a block ID, a detection start date and time, a length of detection time, a sampling frequency of each biological signal, and a comment are associated with the first data is generated. In the above description, the period from the detection start time to the detection end time is regarded as one block, but it may be further divided at a predetermined time interval or a predetermined data size, and a block ID or the like may be associated with each. In the above description, a plurality of types of biological signals are collectively regarded as one block. However, each biological signal data may be divided and associated with a block ID or the like.

  The “second data storage unit” has a function of storing the generated second data. The function of the second data storage unit is realized by a device such as a rewritable memory such as a flash memory or a recording device such as an HDD.

  The “second data transmission unit” has a function of transmitting the accumulated second data to the parent device. The function of the second data transmission unit is realized by, for example, a processor, a communication interface, and a processing program stored in the ROM, like the first data transmission unit. As the communication interface, a wireless system or a wired system can be used.

  Here, the timing for transmitting the second data to the parent device can be arbitrary, and can be transmitted when a transmission request is received from the parent device. It is also possible to send by.

  The “first data generation rule acquisition holding unit” has a function of acquiring the first data generation rule from the parent device and holding it. The function of the first data generation rule acquisition holding unit is realized by, for example, a processor, a communication interface, a storage device such as a RAM or a nonvolatile memory, and a processing program stored in the ROM.

  FIG. 3 is a diagram illustrating an example of the content of the first data generation rule. In the example of this figure, as the generation rule information, the sampling frequency and the number of quantization bits are included for each type of biological signal. Although the example of this figure shows a mode in which the number of quantization bits changes for each type of biological signal, the same number of quantization bits is used regardless of the type of biological signal (common A / D conversion). In the case of using a circuit), it is also conceivable to acquire only the sampling frequency as the first data generation rule.

  For example, the generation rule information is received from the master unit together with the first data transmission command and held in the RAM, and the MPU rewrites the contents of the control register of each sensor I / F based on the generation rule information. In addition, the first data generation rule is received from the master unit independently of the first data transmission command, and stored in the nonvolatile memory as setting information. When the MPU receives the first data transmission command, each sensor I / O It is also possible to rewrite the contents of the F control register.

  In addition, a configuration is also possible in which a plurality of rules for generating the first data are acquired from the parent device and held in a nonvolatile memory or the like. In addition, when there are a plurality of parent devices that are communication partners, it is conceivable to store each generation rule in association with the terminal ID of each parent device.

  The “second data generation rule acquisition holding unit” has a function of acquiring and holding a generation rule of second data from the parent device. The function of the second data generation rule acquisition holding unit is the same as that of the first data generation rule acquisition holding unit, and is realized by, for example, a processor, a communication interface, a storage device such as a flash memory, or a processing program stored in the ROM. .

  As described above, the rule for generating the second data is information necessary for blocking when the first data is blocked in a predetermined unit. When the first data is compressed, the compression rate and the compression method are used. In the case of encrypting the first data, it is information specifying the type of encryption. A rule for generating the second data may be a processing program for generating the second data, but includes information used in the processing program. That is, the processing program itself for generating the second data is held in advance in the biological data transmitting slave unit, and includes a mode in which parameters used for the processing program are received from the master unit as the second data generation rule. It is.

  As described above, as a process of generating the second data by blocking the first data, as described above, a plurality of types of biological data obtained from the data acquisition start time to the data acquisition end time at an arbitrary date and time are regarded as one block. It is conceivable to associate identification information such as block ID, detection start time, length of detection time, data size, sampling frequency of each biological data with the data of the block.

  Note that there may be a case where the rule for generating the second data overlaps with the rule for generating the first data. For example, when generating the second data by associating the identification information with the first data as described above, the sampling frequency of each biological data is also included in the first data generation rule. In this case, the overlapping information is both a first data generation rule and a second data generation rule.

  Since the processing of the second data generation rule acquisition holding unit and the function of the first data generation rule acquisition holding unit are common, all or part of the hardware or software of the first data generation rule acquisition holding unit is transferred to the second data It can also be used as a generation rule acquisition holding unit.

  The timing for acquiring the second data generation rule from the parent device can be acquired when the second data transmission request is received from the parent device, and is independent of the second data transmission request. It is also possible to obtain the setting information from the master unit at an arbitrary timing. It is also possible to acquire the first data together with the generation rule.

  The “biometric data transmission command accepting unit” has a function of accepting a biometric data transmission command from the parent device. The function of the biological data transmission command receiving unit is realized by, for example, a processor, a communication interface, and a processing program stored in the ROM.

  Here, examples of the biometric data transmission command include a first data transmission command and / or a second data transmission command. When the biometric data transmission command accepting unit accepts the transmission command, the biometric data transmission command accepting unit notifies the first data transmitting unit or the second data transmitting unit of acceptance of the transmission command, and the first data transmitting unit or the second data transmitting unit that has received the notification. Transmits the first data and the second data to the main unit.

  The information on the first data transmission command mainly includes information for notifying the timing at which the transmission of the first data should be started. It is also possible to consider information for notifying transmission requests of biometric data of this type (for example, only electrocardiographic waveform biometric data).

  The information on the second data transmission command mainly includes information (one or a plurality of block IDs, etc.) specifying one or a plurality of second data to be transmitted, but is held in the second data storage unit. Information for notifying all the transmission requests for the second data, information for notifying the handling of the second data after transmission (such as data erasure), and the like are also conceivable.

  In addition, when the biometric data transmission command is received together with the first data generation rule and / or the second data generation rule, the biometric data is generated based on the generation rule, and these generation rules are not received together. Can generate biometric data based on a generation rule or a default generation rule received from the parent device in the past.

  It is also possible to include information on the terminal ID of the biometric data transmitting slave that is the source of the biometric data and the terminal ID of the master that is the destination of the biometric data in the biometric data transmission command. In particular, when there are a plurality of biometric data transmission slave units and a plurality of master units, there are a plurality of groups for performing transmission / reception of biometric data. Therefore, the transmission source and the transmission destination may be clarified by the terminal ID. Conceivable.

  Note that, from the viewpoint of power saving, when the biometric data transmission command is not received from the parent device, the function of the biometric signal detection unit can be stopped. In this case, when the biometric data transmission command accepting unit accepts the transmission command, the biometric signal detection unit notifies the biomedical signal detection unit of acceptance of the transmission command, and the biometric signal detection unit that has received the notification starts detecting the biometric signal. .
