Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information measurement devices and sphygmomanometers do not effectively reduce the processing load of processors when writing and transmitting biological data, leading to potential delays in processing.
Innovation Solution
A measurement device with separate first and second processors, where the first processor measures and transmits biological data to the second processor without delivery confirmation, and receives result information after sensing ends, allowing the second processor to manage memory operations, thereby reducing the processing load on the first processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first processor performs delivery confirmation for each biological data transmission to the second processor, then the reliability of data transmission is improved, but the processing time and complexity increase
Solution Approach 1:
The system performs preliminary action by having the first processor transmit biological data to the second processor without delivery confirmation during the sensing period. The second processor independently manages memory writing and provides result information after sensing ends, thereby avoiding time-consuming delivery confirmations during critical measurement phases while ensuring data reliability through post-sensing verification.
2Productivity
If the first processor transmits biological data to the second processor without delivery confirmation, then the processing speed is improved, but the reliability of data transmission deteriorates
Solution Approach 1:
The system implements feedback mechanism where the second processor provides result information to the first processor after sensing ends, indicating whether the biological data was successfully written to memory. This feedback loop ensures data transmission reliability is maintained despite the absence of real-time delivery confirmation during the high-speed data acquisition phase.
3Device complexity
If a single processor handles both measurement and wireless communication tasks, then the device complexity is reduced, but the processing load and potential delays increase
Solution Approach 1:
The system applies segmentation by dividing processor functions into two distinct processors: the first processor dedicated to measurement and data acquisition, and the second processor dedicated to wireless communication and memory management. This functional segmentation eliminates processing conflicts and delays while maintaining relatively simple device architecture through clear task separation.

AI summary
A measurement device, a control method, and a control recording medium that can reduce a processing load of a processor and suppress a delay in processing such as measurement are provided. A measurement device according to one aspect of the present invention includes a main MCU configured to perform measurement based on biological data obtained by a sensor, a communication IC configured to perform wireless communication with an information terminal, and a non-volatile memory connected to the communication IC. The main MCU sequentially transmits the biological data obtained during sensing by the sensor, to the communication IC without performing delivery confirmation and writes the biological data into the non-volatile memory, and receives result information regarding writing of the biological data to the non-volatile memory from the communication IC after the sensing ends. The communication IC transmits, to the information terminal, the biological data written into the non-volatile memory.
