In addition, a standard wireless module is installed in the detection equipment, and a radio frequency port of the wireless module to be detected is connected with a radio frequency port of the standard wireless module through an attenuator. Meanwhile, the wireless detection system also comprises a prompter, and in practical application, the wireless detection system can control the prompter to send out a prompt signal representing the detection result according to the corresponding detection result.
As shown in fig. 1, a schematic flow chart of a detection method of a wireless detection system according to the present invention is shown, where the method includes the following steps:
s110, detecting whether the wireless module to be tested meets the test requirements.
As mentioned above, the wireless detection system provided by the present invention includes a wireless device and a detection device. In this embodiment, for convenience of description and understanding, please refer to fig. 7 exemplarily, in which the wireless device is a bottom board, the detection device is a standard board, the wireless module to be tested is a LoRa module to be tested, and the standard wireless module is a standard LoRa module. Also install the loRa module that awaits measuring on the bottom plate, install standard loRa module on the standard board, and the radio frequency port of the loRa module that awaits measuring passes through the attenuator with the radio frequency port of standard loRa module and is connected, and then be connected with the radio frequency line between attenuator and two radio frequency ports, guarantee the normal transmission of signal.
In this step, it is first required to test whether the LoRa module to be tested meets the test requirements. Specifically, the method comprises the following steps:
s1101, detecting whether the wireless module to be detected exists.
In this step, the bottom plate detects whether the LoRa module to be detected exists.
And S1102, if so, setting the wireless module to be tested to be in a receiving state.
Further, if the loRa module to be tested on the bottom plate is judged to exist, the loRa module to be tested is set to be in a receiving state, and the testing requirement is met at the moment. It can be understood that the LoRa module to be tested in the receiving state is ready to receive the data packet sent by the standard LoRa module at any time.
And S120, if so, setting a signal interface for connecting the wireless equipment and the detection equipment to be in a preset level state.
As shown in step S110, when it is determined that the LoRa module to be tested meets the testing requirement, the signal interface GPIO connecting the control board and the standard board is set to the preset level state. In this embodiment, the predetermined level state is a high level state; in other embodiments, the preset level state may also be another level state, such as a low level state, and the preset level state is set on the premise of correctly determining the current state of the to-be-tested LoRa module, which is not limited herein.
And S130, when the detection equipment detects that the signal interface of the wireless equipment is in a preset level state, controlling data interaction between the standard wireless module and the wireless module to be detected.
As above step S120, after the standard board detects that the GPIO is at the high level, the standard LoRa module and the LoRa module to be tested are controlled to perform data interaction. Specifically, the method for data interaction includes the following steps:
and S1301, controlling the standard wireless module to send first data to the wireless module to be tested with the first power, and setting the standard wireless module to be in a receiving state.
In this step, after the standard LoRa module is controlled to send the first data to the LoRa module to be tested with the first power, the standard LoRa module is set to the receiving state. It can be understood that, the standard LoRa module in the receiving state is to receive the data packet sent by the LoRa module to be detected, and the first power is the highest power of the standard LoRa module, so as to ensure the maximum transmission of the wireless signal. Of course, in other embodiments, the first power may also be other powers, and is not limited herein.

In this step, the corresponding transmission power of the first data packet sent by the standard LoRa module to the LoRa module to be tested is the first power, and the signal strength received by the LoRa module to be tested is the first signal strength value. The second data packet sent by the standard LoRa module by the to-be-tested LoRa module has the corresponding transmission power of the second power, and the signal strength received by the standard LoRa module is the second signal strength value.
It should be noted that, the signal strength value of the received data packet of the standard LoRa module or the LoRa module to be measured follows the following formula:
RSSI ═ transmission power-radio frequency line loss-attenuator attenuation value
The RSSI represents a signal strength value corresponding to the received data packet, and the transmission power is corresponding to the transmission power of the opposite transmission module when the data packet is transmitted. In addition, the loss of the radio frequency line and the attenuation value of the attenuator are fixed values, and are related to the properties of the radio frequency line and the equipment.
In this step, the wireless performance of the wireless module to be tested is detected and the detection result is output. Specifically, the detection items include: (1) whether the frequency error is normal or not; (2) whether the transmit path or the receive path is normal. As a supplementary note, if it is ensured that the transmission path or the reception path is normal, it is necessary to satisfy that the radio frequency transmission power, the reception sensitivity, and the frequency error are all normal at the same time. In this embodiment, the wireless detection system may control the prompter to generate a corresponding prompt signal according to an actual detection result, so as to prompt a specific performance or a fault of the to-be-detected LoRa module.
Example two
As shown in fig. 2, a method for determining a wireless detection result according to a second embodiment of the present invention is used to confirm a detected result of wireless performance of a wireless module under test, and the method specifically includes the following steps:
s210, judging whether the wireless module to be tested receives the first data within a preset time period.
Specifically, it is determined whether the LoRa module to be tested receives the first data packet sent by the standard LoRa module within the time specified by the timer. In this step, the preset time period is 5 s. In other embodiments, the specific duration of the preset time period may also be other values, which are not specifically limited herein, and the specific setting may be performed on the premise of ensuring accurate determination of the test result.
S220, if not, judging that the receiving channel of the wireless module to be tested is abnormal.
As in step S210, if the first data packet sent by the standard LoRa module is not received after exceeding 5S, it is determined that the receiving path of the LoRa module to be tested in the bottom board is abnormal.
And S230, controlling the prompter to send a first prompt signal for representing the abnormity of the receiving channel of the wireless module to be tested.
Further, please refer to fig. 7, in the above steps, after the receiving path of the LoRa module to be tested is determined to be abnormal, the controller generates a prompt signal correspondingly, and controls the prompt device to prompt correspondingly. In addition, in the present invention, the prompter generally includes a red LED module and a green LED module. And when the abnormity is confirmed, controlling the red LED module to generate a red signal. Additionally, in practical application, the fault alarm is not limited to prompt in a way of alarm by a prompter, and the fault alarm can be combined with equipment with a prompting function, such as a display, a loudspeaker and the like, for example, corresponding faults are displayed in a fault code or text way, or simply sent out sound, so that an operator can conveniently and accurately grasp actual fault problems in time.

In this step, whether the signal strength of the to-be-tested LoRa module when receiving the first data packet sent by the standard LoRa module is within the preset range is determined.
S320, if yes, determining whether the second signal strength value is within a second predetermined range.
As shown in step S310, if the corresponding signal strength when the to-be-tested LoRa module receives the data packet is within the first preset range, it may be determined that the radio frequency transmission power, the receiving sensitivity, and the frequency error of the standard LoRa module are all normal, and it may be determined that the receiving path of the to-be-tested LoRa module is normal.
Further, at this time, the situation that the to-be-detected LoRa module sends data to the standard LoRa module needs to be detected and judged. That is, the corresponding signal strength value when the standard LoRa module receives the data packet sent by the to-be-tested LoRa module.
S330, if yes, judging that the radio frequency emission power, the receiving sensitivity and the frequency error of the wireless module to be tested are normal.
In this step, if the second signal strength value corresponding to the standard LoRa module receiving the data sent by the LoRa module to be detected is within the second preset range, it can be determined that the radio frequency transmission power, the receiving sensitivity, and the frequency error of the LoRa module to be detected are all normal. It should be added that if the frequency error between the LoRa module to be tested and the standard LoRa module is large, the sending and transmission of the data packet between the LoRa module to be tested and the standard LoRa module cannot be performed, that is, a fault exists between the LoRa module to be tested and the standard LoRa module.
And S340, controlling the prompter to send out a second prompt signal which represents that the radio frequency emission power, the receiving sensitivity and the frequency error of the wireless module to be tested are normal.
As shown in step S330, after determining that the radio frequency transmission power, the receiving sensitivity, and the frequency error of the LoRa module to be tested are normal, the controller generates a prompt signal correspondingly, and controls the prompt to prompt. It can be understood that the detection is normal at this time, and the green LED module in the prompter is controlled to prompt.

And S420, if not, judging that the transmitting path of the wireless module to be tested is abnormal.
It can be understood that, since the standard LoRa module can receive the data packet sent by the LoRa module to be tested, the frequency error between the standard LoRa module and the LoRa module is satisfactory. However, if the signal strength of the data packet received by the standard LoRa module is not within the preset range, it may be determined that the transmission path of the LoRa module to be tested is abnormal. E.g., transmit power anomalies, etc.
And S430, controlling the prompter to send a third prompt signal for representing the abnormity of the transmitting channel of the wireless module to be tested.

As mentioned above, if the frequency error between the LoRa module to be tested and the standard LoRa module is large, the data packet cannot be sent and transmitted between the LoRa module to be tested and the standard LoRa module. In this step, the standard LoRa module does not receive the data packet sent by the LoRa module to be tested, and it can be determined that the frequency error of the LoRa module to be tested is abnormal.
It should be added that, if the standard LoRa module receives a data packet sent by the LoRa module to be tested, it is continuously determined whether the second signal strength corresponding to the received data packet is within a second preset range. And if the second signal intensity is not within a second preset range, judging that the sending path of the LoRa module to be tested is abnormal.
And S530, controlling the prompter to send a fourth prompt signal for representing the frequency error abnormity of the wireless module to be tested.
In this step, the controller generates an abnormal signal and controls the red LED module in the prompter to prompt.

As mentioned above, if the frequency error between the LoRa module to be tested and the standard LoRa module is large, the data packet cannot be sent and transmitted between the LoRa module to be tested and the standard LoRa module. In this step, the to-be-tested LoRa module does not receive the data packet sent by the standard LoRa module, and it can be determined that the frequency error of the to-be-tested LoRa module is abnormal.
