Description

Technical Field

[0001] The present invention relates to the technical field of test boxes, and more specifically to a WiFi comprehensive test box for a smart scale and a test method thereof. Background Art

[0002] At present, the WiFi function test of the general intelligent WiFi scale production line is as follows: using an old Android phone with Android 6.0 system to develop a special WiFi test APP to perform WiFi function test (including WiFi wireless radio frequency signal strength and WiFi data transmission test);

[0003] When using an Android 6.0 phone, after a long test of the APP calling the system WiFi, it is easy to fail to search for the AP hotspot sent by the WiFi smart scale, resulting in a situation where the test cannot be performed normally. In addition, the system response of an Android 6.0 phone is slow, resulting in a long test time of about 60 seconds for the WiFi function of a smart WiFi scale on the production line. When the product is testing the WiFi function, there is a serious backlog, resulting in reduced production capacity and increased costs. At the same time, for new phones with an Android system greater than 6.0, due to the low power consumption of the Android system, the WiFi list of the mobile phone system is cached, and it is impossible to search for the latest WiFi smart scale in real time, and it is impossible to install the corresponding test APP to test the WiFi function of the WiFi smart scale.

[0004] In addition, due to the limitations of the iOS system, the APP test program on the Apple phone cannot obtain the signal strength information in the WiFi list searched by the system, resulting in the inability to install the test APP to test the WiFi function of the smart scale. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a WiFi comprehensive test box for a smart scale, which greatly improves the production efficiency of the smart scale. The WiFi function test of a smart scale can be completed in about 10 seconds instead of the original 60 seconds.

[0007] The WiFi module obtains the unique identification code of the smart scale and the WiFi signal strength, and transmits the obtained WiFi signal strength to the main control Bluetooth module through the UART bus;

[0008] The WiFi module obtains the test data of the smart scale from the system server through a unique identification code to transmit the data to the main control Bluetooth module. The main control Bluetooth module compares the obtained WiFi signal strength and the test data with a preset threshold range respectively. When the comparison result is within the threshold range, a smart scale test qualified signal is output; otherwise, a smart scale test unqualified signal is output.

[0009] Furthermore, it also includes a display unit, which includes a color display screen and a driver chip, the driver chip is electrically connected to the color display screen, and the driver chip is communicatively connected to the main control Bluetooth module via an SPI bus. When the WiFi signal strength and the test data are within a threshold range, the main control Bluetooth module outputs a smart scale test qualified signal, and the driver chip drives the color display screen to display a green icon; when the WiFi signal strength or the test data are not within the threshold range, the main control Bluetooth module outputs a smart scale test unqualified signal, and the driver chip drives the color display screen to display a red icon.

[0010] Furthermore, it also includes a power supply unit, which includes a battery, a step-down module and a charging management module. The step-down module and the charging management module are both connected to the battery. The step-down module is used to receive the voltage output by the battery and convert it into a 3.3V voltage output to power the main control Bluetooth module; the charging management module includes a charging management chip and a Type-c charging port. The charging management chip is used to detect the voltage and current status of the battery. The Type-c charging port is connected to an external power supply to charge the battery.

[0011] Furthermore, it also includes a front-end acquisition chip, which is connected to the main control Bluetooth module through a UART bus. The front-end acquisition chip receives analog signals collected by external sensors or signal sources and converts the analog signals into digital signals.

[0012] Further, the shell body includes a lower shell and an upper cover, the lower shell and the upper cover are detachably connected, the inner wall of the lower shell is provided with at least one card slot, the upper cover is correspondingly provided with a card protrusion, the card protrusion includes a first protrusion connected to the upper cover and a second protrusion connected to the first protrusion, the first protrusion and the second protrusion are perpendicular to each other, and the upper cover can be moved along the length direction of the lower shell so that the second protrusion is embedded in the card slot.

[0013] Furthermore, a charging hole is provided on one side wall of the lower shell, and the charging hole is used for allowing a charging cable to pass through.

[0014] Furthermore, a color screen connector is provided on the mainboard unit, and the mainboard unit is connected to the display unit via the color screen connector.

The master control Bluetooth module compares the acquired WiFi signal strength and the test data with the preset threshold range respectively. When the comparison result is within the threshold range, the smart scale test qualified signal is output, otherwise the smart scale test failed signal is output.

[0021] Furthermore, the test data includes the weight of the smart scale, the impedance value of the smart scale, and the WiFi data transmission rate.

[0035] In this embodiment, the unique identification code is the SSID, MAC address or specific identifier issued by the WiFi chip built into the smart scale, which is used to ensure that the test box can accurately connect to and identify the target smart scale. The WiFi module 22 searches for and connects to the smart scale within a certain range, thereby obtaining the unique identification code and WiFi signal strength of the smart scale, and transmits the obtained WiFi signal strength to the main control Bluetooth module 21 through the UART bus.

[0036] The WiFi comprehensive test box provided in the embodiment of the present invention uses the acquired unique identification code, and the WiFi module 22 obtains the test data related to the smart scale from the system server through the network communication protocol (such as HTTP, MQTT, etc.), such as the weight of the smart scale, the impedance value of the smart scale, the WiFi data transmission rate, etc., and then the WiFi module 22 transmits the acquired test data to the main control Bluetooth module 21. The main control Bluetooth module 21 receives the WiFi signal strength and test data sent by the WiFi module 22, and compares the WiFi signal strength and the test data with the preset threshold range. According to the comparison result, the main control Bluetooth module 21 outputs a signal indicating that the smart scale test is qualified or unqualified; if the WiFi signal strength and the test data are both within the preset threshold range, a qualified signal is output; otherwise, an unqualified signal is output.

[0037] It should be noted that the threshold range is pre-set based on the design specifications and industry standards of the smart scale and is used to determine whether the performance of the smart scale meets the standards.
