Scene introduction
The test device of the wearable data acquisition terminal provided in one or more embodiments of the present disclosure is used for testing a control board of a terminal to be tested, where the control board is called a board to be tested 301.

In order to obtain higher test efficiency, when a specific terminal to be tested is tested, the best implementation mode is to continuously detect control boards of a plurality of terminals to be tested of the same type. These control boards have the same shape, size and function.
The test machine 20 is configured with a test control program, and after the test probe 21 establishes a connection with the board 301 to be tested, the test program for the control board of the terminal to be tested is burned into the board 301 to be tested under the control of the test control program. And then reset by the board 301 to be tested and begin the test procedure. The test program is configured to execute functions of the terminal under test in cooperation with the test control program. Test control programs and configurations of test programs are performed using knowledge disclosed in the art.
The embodiment of the present disclosure provides a testing device for a wearable data acquisition terminal, please refer to fig. 1, including:

a test probe 21 for connecting the board 301 to be tested and the tester 20,
the testing machine 20 is configured to burn a testing program into the board 301 to be tested through the testing probe 21, receive feedback of the testing program, obtain a testing result, and supply power to the board 301 to be tested, where the testing machine 20 includes a communication interface for connecting with the host computer 10.
The test fixture 40 is matched with a board 301 to be detected of a testing device of the wearable data acquisition terminal, and fixing of the board 301 to be detected is achieved. In one or more embodiments of the present disclosure, the board 301 to be inspected is fixed by being placed on the inspection stage 405 and being limited in the horizontal direction. The limit in the vertical direction is achieved by gravity and the contact limit of the test probe 21. The test probes 21 effect connection of the tester 20 with the board 301 to be inspected, so that the tester 20 can effect electrical connection with the board to be inspected. The electric connection realizes the functions of supplying power to the board 301 to be detected by the testing machine 20, realizing communication between the board 301 to be detected and the testing machine 20 and realizing the function of reading the potential state of a certain position of the board 301 to be detected by the testing machine 20. I.e. the electrical connection comprises an energy connection and an information interaction connection. Bluetooth communication or communication is established among the board 301 to be detected, the testing machine 20 and the upper computer 10 through USB. Other ways of establishing communication that are disclosed in the art are also within the scope of the present description.
Referring to fig. 2, the testing machine 20 is provided with at least one testing module, where the testing module is a power consumption testing module, a signal generating module, a channel configuration module, an indicator light testing module or a magnetic induction awakening module, the power consumption testing module is used for testing standby power consumption or working power consumption of the board 301 to be detected, the signal generating module is used for generating a testing signal, the indicator light detecting module is used for detecting a working state of the board 301 to be detected carrying the indicator light, the channel configuration module is used for configuring a starting state of the testing module of the testing machine, and the magnetic induction awakening module is used for detecting a working state of the magnetic induction awakening unit carried by the board 301 to be detected.
For example, the control board of the wearable dynamic electrocardiographic monitoring terminal, that is, the control board of the wearable dynamic electrocardiographic monitoring terminal, is used as the board 301 to be detected in this specification. The method relates to the items of sleep power consumption detection, power consumption detection during operation, electrocardiograph data derivation and clearance detection, equipment number checking, simulation acquisition detection, indicator light detection, six-axis detection, magnetic induction awakening detection, algorithm verification, voltage detection and the like. After the board 301 to be inspected is clamped by the test fixture 40, the inspection probe contacts with the board 301 to be inspected and establishes electrical connection. The positions and the number of the detection probes are determined according to the board 301 to be detected. The determination method is performed in accordance with the techniques disclosed in the art.
The foregoing tests are performed by using a specific test module, and the specific implementation scheme is performed by referring to the technology disclosed in the art. Illustratively, the control chip of tester 20 employs an NRF52833 chip. The test fixture comprises 8 paths of 12bit and 200ksps ADC (analog to digital converter) for collecting voltage signals converted by certain test items, controlling a test fixture state indicator lamp and connecting with an upper computer 10 through a communication interface so as to support richer test functions and data analysis. The communication interface may be a wired connection interface, such as a USB connection, an RS485 connection, a serial bus connection, etc. Wireless connection interfaces, such as bluetooth connection, WIFI connection, zigBee connection, etc. may also be employed. In the sleep power consumption detection and the power consumption detection process in the running process, an INA180A2IDBVR current detection amplifier is used, the power consumption data is collected by an ADC of an NRF52833, and the NRF52833 transmits the power consumption data to the upper computer 10 for analysis and recording through Bluetooth, so that the long-time detection and the recording of the power consumption data are supported. Because of the small sleep power consumption, after the INA180A2IDBVR performs the first-stage amplification, the LMV321IDBVR operational amplifier is adopted to perform the second-stage amplification, and the second-stage amplification is acquired by the ADC of the NRF 52833. The NRF52833 transmits the power consumption data to the host computer 10 through bluetooth for analysis and recording.
In the indicator lamp test module, an optical signal is converted into a voltage signal through a GL5516 photoresistor and is collected by an ADC of NRF 52833. The upper computer 10 or the NRF52833 controls the indicator light of the board 301 to be detected to turn on, and then controls the GL5516 to collect and receive the feedback data. The programming of the test program is performed through a download interface reserved by the test machine 20 or by using a USB interface. The electrocardiograph data is exported and connected with the upper computer 10 through the USB or connected with the upper computer 10 through the testing machine 20, and the upper computer 10 can read data and also can clear electrocardiograph data. The DRV8870DDAR chip is used for starting the electromagnet to control dormancy and awakening of the tested device. The channel configuration module switches the connection between different test modules and the detection probes by closing or opening the corresponding electronic switches, so that the starting state of the test modules is configured. The signal generating module IS configured by another NRF52833 chip to generate signals by using an LTC2642CMS-16#PBF chip, and then the signals are converted by using an LT1678IS8#PBF chip to be used as input signals.
