Then please refer to Figure 3, and at the same time with Figure 2. FIG. 3 is a flowchart showing measurement steps of the portable measurement system. In FIG. 3, step 90: measure the physical signal and process the physical signal to obtain the processed signal. In this step, the functional unit 11022 is used to detect the physical signal, and the analog signal processing module 11042 and the digital signal processing module 11062 process the signal to obtain the processed signal. In this step, the processed signal may be a vibration signal , Sound signals, physiological signals, electronic waveform signals, optical signals or image signals. Next, step 92: measure and read the power status of the power supply device and the second power supply device of each module unit, and determine the sensing function corresponding to the portable measurement system according to the identification code corresponding to the module unit. In this step, the control unit 1204 is used to detect and read the power supply devices 11026 of each module unit such as the sensing module 11022, the analog signal processing module 11042, the digital signal processing module 11062, and the wireless transmission module 120, 11046, 11066, 1208 power state, and determine the sensing corresponding to the portable measurement system 1 according to the combination of the identification codes corresponding to the sensing module 11022, the analog signal processing module 11042, and the digital signal processing module 11062 Features. Next, in step 94: the processing signal is sent to the electronic device, and the measurement value, the sensing function and the total power of the current portable measurement system corresponding to the processing signal are displayed on the electronic device by the mobile application. In this step, the processing signal is transmitted to the electronic device 30 via the wireless transmission unit 1202, and the measurement value of the processing signal is displayed on the electronic device 30 by the mobile application 302, for example, if it is measuring noise, then The decibel value of the current environment is displayed on the electronic device 30; if the blood pressure is measured, the user's blood pressure value (mmHg) is displayed on the electronic device 30; if the air pollution is measured, the electronic device 30 Shown are fine suspended particles (PM _2.5 (μg/m ³ )), ozone (O ₃ ) (ppb, suspended particles (PM ₁₀ (μg/m ³ )), carbon monoxide (CO (ppm)), sulfur dioxide (SO ₂ (ppb)) and/or nitrogen dioxide (NO ₂ (ppb)).

Then please refer to Figure 4. FIG. 4 is a flowchart showing the steps of the control unit in the portable measurement system to judge the power and charge. 4 is a further illustration of detecting and reading the power states of the power supply device and the second power supply device of each module unit in step 92 of FIG. 3. Similarly, in the process of explaining FIG. 4, FIG. 2 is also included. In FIG. 4, step 922: determine which power state of the power supply device in the portable measurement system has the lowest battery level. In this step, the control unit 1204 is used to read the power status of each power supply device 11026, 11046, 11066, 1208 of each module unit 11022, 11042, 11062 and/or wireless transmission module 120 through the charging bus 60, and Determine which of the power supply devices 11026, 11046, 11066, 1208 has the lowest battery power.

Next step 924: the control unit controls one of the charging circuits with the lowest battery capacity to be in an on state, and controls the charging terminal to pass the charging circuit with the on state at a constant current to the battery with the lowest battery in the portable measurement system The power supply device with the electric quantity performs a charging procedure so that the power supply device with the lowest battery capacity reaches a preset value. In this step, since it is obtained in step 922 that one of the power supply devices 11026, 11046, 11066 or 1208 in the portable measurement system 1 has the lowest battery power, the control unit 1204 controls the corresponding battery power with the lowest The charging circuit 11024, 11044, 11064 or 1206 is set to the on state, while the remaining charging circuits are still maintained in the off state, and the control unit 1204 controls the connection from the charging terminal 1210 to an external power supply (not shown in the figure) It also provides a charging power source and performs a charging process at a constant current through the charging circuit with the on state for the power supply device 11026, 11046, 11066, or 1208 with the lowest battery power, so that the power supply device 11026, 11046 with the lowest battery power The battery power of 11066 or 1208 reaches a preset value. In the embodiment of the present invention, the preset value of the battery power is 70%.

In addition, it should be noted that, since the charging power provided by the charging terminal 1210 is a USB charging power supply with a general 5 volt (V, volt) voltage and 500 milliampere (mA), the power supply device 11026, 11046, 11066 and The second power supply device 1208 is a lithium battery, so when the charging power source is a USB charging power source, the power supply device 11026, 11046, 11066, or 1208 with the lowest battery power is charged with the maximum current at a constant current. A single power supply device can quickly charge it to at least 70% of the battery charge, so it can solve the problem of slow charging caused by the average current shunt to different power supply devices in the prior art.

Next at step 926: when the power supply device with the lowest battery charge reaches the preset value, the control unit compares all the power supply devices of the portable measurement system to find the power supply device with a relatively low battery charge . In this step, in step 924, after charging the power supply module with the lowest battery power in the entire portable measurement system 1 to 70% by fast charging, the control unit 1204 is used to measure the portable measurement All the power supply devices 11026, 11046, 11066, and 1208 of the system 1 are compared to find out the power supply devices 11026, 11046, 11066, or 1208 which have relatively low battery power among them. If it is found that the power supply device 11026, 11046, 11066, or 1208 has a relatively low battery power, step 928 is performed. If not, proceed to step 932.

At step 928: the control unit controls the charging circuit corresponding to the power supply device having a relatively low battery power to the conductive state. Since all the power supply devices 11026, 11046, 11066, and 1208 of the portable measurement system 1 are compared with each other in step 926, the battery power is relatively low, so the control unit 1204 will use the power supply devices 11026, 11046, 11066 Or the charging circuit 11024, 11044, 11064 or 1206 corresponding to 1208 forms a conducting state. Next, at step 930: the control unit controls the charging terminal to provide charging power at a constant current through the on-state charging circuit to perform a charging procedure on the power supply device having a relatively low battery power, so that the battery power of the power supply device exceeds a preset value. In this step, the control unit 1204 controls the charging terminal 1210 to provide charging power to charge the power supply device 11026, 11046, 11066, or 1208 with a relatively low battery power through the turned-on charging circuit, while still charging at a constant current Charging the power supply device 11026, 11046, 11066 or 1208 until the battery power of the power supply device 11026, 11046, 11066 or 1208 exceeds a preset value.

Next, in step 932: when the battery power of all power supply devices of the portable measurement system exceeds a preset value, the control unit controls the charging circuit of each module unit and the second charging circuit of the wireless transmission module to The conductive state enables the control unit to control the charging terminal to provide charging power at a constant voltage to charge the power supply device of each module unit and the second power supply device of the wireless transmission module via the charging circuit and the second charging circuit, so that it is portable The battery capacity of all battery supply devices of the digital measurement system reaches saturation. Through the above step 930, the battery power of all the power supply devices 11026, 11046, 11066, and 1208 in the portable measurement system 1 exceeds the preset value of 70%. At this time, the power supply devices 11026, 11046, 11066, and 1208 The battery is nearly full, and there is an internal pressure difference. Therefore, it is necessary to fully charge all the power supply devices 11026, 11046, 11066, and 1208 of the portable measurement system 1 with a maximum voltage of 5V at a constant voltage. The unit 1204 must control all the charging circuits 11024, 11044, 11064, and 1206 of the portable measurement system 1 to be turned on at the same time, and the charging power provided by the charging terminal 1210 passes through the charging bus 60 through the charging circuit 11024 in an evenly shunted manner , 11044, 11064, and 1206 charge the power supply devices 11026, 11046, 11066, and 1208 until the battery power of the power supply devices 11026, 11046, 11066, and 1208 reaches saturation.
