One of the utility model main points are the developments of special N-type coating probe, it two is develop supporting APP software on mobile terminals, and the key of N-type coating probe is also in the design of circuit, this special percussion mechanism comprises 3.5mm audio jack, 3 core cables, data acquisition and code modulated circuits module 1, percussion mechanism is popped one's head in, circuit module is because its volume is little, both percussion mechanism probe can be integrated in inner, also accessible site (is similar to the line traffic control terminal of walkman) on audio-frequency electric cable, is approximately 1.5m according to audio-frequency electric cable total length.
Principle of work of the present utility model is, the signal that N-type probe A exports carries out level conversion through the circuit of an electric capacity and two resistance compositions, then be input in microcontroller B and carry out data acquisition, the data collected are modulated according to communication protocol by single-chip microcomputer, be modulated into sound signal, started to mobile terminal D by tone frequency channel wire C.The APP software run on mobile terminals carries out data processing to the result that microcontroller B sends, display, the operations such as preservation.
Key of the present utility model is the connection of circuit module, microminiaturization, low power dissipation design.First as far as possible reduce device volume, circuit builds the following device of employing for this reason: microprocessor adopts MKL05Z32VFK4(QFN24 encapsulation), crystal oscillator adopts 2520 encapsulation, and capacitance resistance ware removes the higher resistance of precision requirement, and all the other all adopt 0402 encapsulation.
N-type coating probe (sensor) due to its frequency higher, modulate circuit (oscillatory circuit) is the implanted sensor end near coil generally, export a frequency signal N1 relevant to thickness of workpiece, this frequency signal is input in microprocessor, just can calculated the thickness of coating by the corresponding relation between thickness frequency.
P3 is 3V button cell, also should at more than 2.3V time voltage is low, and the microcontroller operating voltage used by the utility model can between 1.8V-3.6V.
RIGHT is that the R channel of 3.5mm audio port exports, from mobile terminal APP(such as mobile phone), this signal can reset to microcontroller.After reset, APP sends the instruction of startup work to microcontroller U5 by LEFT, now during the program of microcontroller U5 SHUTDOWN and POWER_EN, SHUTDOWN high level enable according to instruction, TPS61040 boosts, the 3.3V of stable output, after POWER_EN is dragged down, M1 works on power, and exports 1 pin that a road frequency signal N1 is input to U5, the Timer timing module of the corresponding microprocessor of this pin, can the frequency of measuring-signal N1.Use the corresponding relation between frequency and coating thickness realizing implanting, can coating thickness be calculated.After measuring, U5 is encoded to measurement result and is given the APP of mobile terminal by 17 human hair combing wastes.
When not needing to measure, circuit needs to enter holding state, its process is: after microcontroller U5 detects that APP does not send measurement instruction for a long time, SHUTDOWN is set to low level, now TPS61040 stops boosting, now the voltage of test point TP1 is close to cell voltage, but still can supply microcontroller U5 and work.Microprocessor program draws high POWER_EN (16 pin of U5), stops powering to M1, is now equivalent to battery only to microprocessor and several resistance (R9, R10, R23, R24) power supply.The standby current of microcontroller U5 can drop to 2 μ about A, R9, R10, R23, R24 current sinking is no more than 3 μ A, U4 typical case Shutdown electric current is 1 μ A, therefore in the standby state, total current is greatly about 6 μ A, and this power consumption can allow the standby operation of whole system more than 2 years (can allow because circuit board size is less the battery that use capacity is larger a little, assuming that battery electric quantity 100mAh), therefore do not need to use on/off circuit.
