Detailed Description
For the purpose of making the implementation, technical solutions and advantages of the present specification clearer, the technical solutions will be clearly and completely described by examples with reference to the accompanying drawings. It will be apparent that the embodiments described are some or all of the preferred embodiments of the present specification. It should be noted that the test terminal in the present invention includes, but is not limited to, a smart phone, a tablet computer, a smart wearable device, or other displayable terminals with bluetooth function. The RSSI in the present invention is a signal strength Indication received by RECEIVED SIGNAL STRENGTH Indication, and the larger the value is, the shorter the distance is. Various specific values are set forth herein for purposes of understanding and are not intended to be limiting. The terms first, second, etc. in the present invention are only used for distinguishing between objects.
As shown in fig. 1, a preferred embodiment is provided according to the first aspect of the present invention.
The Bluetooth ranging method is based on a test terminal and two targets, wherein the targets can carry out Bluetooth broadcasting, the positions of a first target and a second target are fixed, and the distances between the first target and the second target and the test terminal are different and known;
The client of the test terminal acquires RSSIs of two targets, and a logarithmic formula capable of calculating the distance is fitted according to the acquired RSSIs and the known distance between the targets and the test terminal.
The test terminal obtains the RSSI of the equipment to be tested, substitutes the RSSI of the equipment to be tested into the formula, and calculates the distance between the equipment to be tested and the test terminal.
By the method, distance measurement can be performed, and the distance between the equipment to be tested and the test terminal can be judged. In practical application, the device of the same kind as the device to be measured is selected as the marker post, so that the effect is better, and the measurement error can be reduced.
As shown in fig. 2, a preferred embodiment is provided according to the second aspect of the invention.
A testing method of Bluetooth equipment, which tests the Bluetooth equipment by using a testing terminal, wherein the Bluetooth equipment is equipment to be tested, comprises the following steps:
the RSSI of the first marker post and the RSSI of the second marker post are obtained, the positions of the first marker post and the second marker post are fixed, the distance between the first marker post and the test terminal is 1 meter, and the distance between the second marker post and the test terminal is 3 meters.
According to RSSIs of the first and second targets, fitting a formula to the distances between the first and second targets and the test terminal, wherein the formula is used for calculating an unknown distance;
acquiring the RSSI of the equipment to be tested according to the scanning of the user, substituting the RSSI of the equipment to be tested into the formula, and calculating the distance between the equipment to be tested and the test terminal;
Determining whether the calculated distance is within 2 meters?
If yes, bluetooth connection is carried out on the device to be tested.
And if not, judging that the equipment to be tested is unqualified.
In the process, a tester scans the two-dimensional code of the device to be tested through the APP, obtains the RSSI of the device to be tested, and obtains a formula. If the formula is not acquired, the formula needs to be obtained through initialization. If the formula is obtained, the equipment is scanned within 8 seconds, and if the scanning equipment is overtime, the equipment to be detected is judged to be unqualified. If the equipment is scanned, the distance calculation is carried out on the equipment, and whether the equipment to be detected has a problem is judged according to whether the calculated distance is within 2 meters.
In order to ensure the accuracy of the test, a tester should control the device to be tested to be placed in the range of2 meters of the test device, and if the device to be tested is calculated to be not in the range of2 meters by the method, the device to be tested is considered to be an unqualified product. For example: the bluetooth of the device to be tested is damaged and the bluetooth broadcast of the device cannot be scanned. Also for example: the two-dimensional code of the current equipment is scanned, and because the two-dimensional code is not matched with the equipment, the RSSI of the other equipment is actually obtained, and the other equipment is outside 2 meters, and the equipment to be detected can be judged to be unqualified. In addition, only the device to be tested is in 2 meters, bluetooth connection is carried out on the device to be tested, and manual testing is carried out.
Further, the RSSI of a connection device, which is a device connected with Bluetooth of the test terminal,
According to the comparison of the RSSI of the connected device and the RSSI of the device under test, determining whether the error between them is within 5?
And if yes, testing the connecting equipment.
And if not, judging that the equipment to be tested is unqualified.
In the further process, whether the device actually connected with Bluetooth is the device in scanning can be judged by comparing whether the RSSI in scanning is in a reasonable range or not after the Bluetooth is connected. And a tester can confirm whether the equipment to be tested is qualified or not by observing the condition of the indicator lamp of the equipment to be tested, so that the problem of the equipment is detected. For example: 2 bluetooth charging wires A and B have on the quality inspector's hand, and the two-dimensional code subsides of these 2 charging wires are all in 2 meters within range through range finding judgement charging wire, and after the quality inspector scanned charging wire A, test terminal has actually connected charging wire B, and charging wire A's pilot lamp can not light up this moment, and charging wire B's pilot lamp lights up, consequently further through the condition that await measuring equipment pilot lamp state also can judge charging wire A, B two-dimensional code mismatch.
Further, the detection result is unqualified, and the unqualified reason is prompted.
For example: the scan does not result in a broadcast of the device under test, which may be a loss of bluetooth functionality of the device under test.
The Bluetooth can not be connected, and the Bluetooth can be the fact that the equipment is not matched with the two-dimensional code, or the Bluetooth function of the equipment to be tested is abnormal, or the equipment to be tested is connected by other test terminals.
As shown in fig. 3, an embodiment is provided according to a third aspect of the present invention.
A test system of Bluetooth equipment comprises two targets and a test terminal. In order to save test space and tooling cost, two stations can be tested simultaneously, and the position relationship is shown in figure 3. The two benchmarks are fixed relative to the position of the testing station, the testing terminal moves in the testing station, the distance between the two benchmarks and the testing station is 1 meter and 3 meters respectively, and the testing terminal is used for testing whether the Bluetooth equipment to be tested is qualified or not.
As shown in fig. 4, another embodiment is provided according to a third aspect of the present invention.
A Bluetooth device test system has a positional relationship shown in FIG. 4.
