[0015] The following is combined with Figure 1-2 This application is described in further detail.

[0016] An embodiment of the present application discloses an outdoor wireless device that supports telephone communication and 4G communication.

[0017] Reference Figure 1-2 An outdoor wireless device supporting telephone and 4G communications includes a housing 1 and a wireless host (board). Housing 1 encloses the wireless host and its shape, determined by requirements, can be boxed or spherical. Note that the term "host" here refers to the circuitry within the device's housing 1, not a computer. The wireless host includes an integrated Wi-Fi module, antenna 2, a power module, and a control module. The control module includes a processor, memory, and other peripheral circuits for data analysis and processing. The control module is connected to the Wi-Fi module, antenna 2 is connected to the Wi-Fi module, and the power module is connected to the device's electronic components for power supply.

[0018] It is understandable that if the wireless device needs to be connected to an optical fiber, an Ethernet interface should also be installed. This is a prior art and will not be described in detail. The above-mentioned many settings enable this application to realize the basic functional applications of outdoor wireless devices, but there are many inconveniences. Therefore, this application also includes: SIM card, preferably a 4G card, because the subsequent settings of this application are inefficient with 2G and 3G networks, while 5G has high power consumption and surplus performance.

[0019] The UICC receiving unit is a universal integrated circuit that integrates a terminal card slot. It does not have an embedded UICC but retains the plug-in and pull-out function to facilitate function selection and provide performance expansion conditions. When in use, the SIM card is inserted into the card slot of the UICC receiving unit.

[0020] a link switching module, which is electrically connected to the UICC receiving unit and the control module and is used to turn the UICC receiving unit and the control module on and off; The self-test module can be another independent integrated circuit structure, mounted on the same circuit board as the control module by soldering pins, which is equivalent to a wired data connection. The self-test module also includes a controller and a Wi-Fi module connected to the controller. It is important to note that compared to the device's external Wi-Fi module, this Wi-Fi module should be low-power and short-range to reduce costs and performance losses.

[0021] The self-test module is configured as follows: connecting to the designated cloud platform via the WIFI module at a preset frequency and obtaining a random code with a timestamp; the frequency can be 5 minutes / time, or 1 second / time, etc., with a lower frequency being preferred, because a delay of a few minutes in the application environment has relatively little impact, and this method can reduce a large amount of data, etc.; the generation of random codes can be achieved by loading a random number generation applet on the cloud platform, which is an existing technology and will not be elaborated on.

[0022] Based on the above, the control module is configured as follows: S11. If the device is powered on, it obtains a random code from the self-test module via a wired connection, reads the timestamp, and calculates the time difference t1 from the current time.

[0023] The reason why the above data contains random codes is to prevent misidentification; the time difference t1 is normalized to seconds to facilitate further data analysis.

[0024] S12. Determine whether the time difference t1 is greater than the abnormal trigger threshold T, for example, T = double the random code acquisition interval. If so, control the link switching module to connect the UICC receiving unit and the control module, that is, enable the device to go online with 4G network communication capabilities; Afterwards, a device network failure prompt is sent to a designated platform (via the SIM card), and when the UICC receiving unit and the control module are connected, an administrator instruction is obtained from the self-test module; wherein the administrator instruction at least includes a device restart instruction.

[0025] According to the above settings, the device can automatically detect network failures and launch functions such as 4G communication, through which prompts are sent to the designated cloud platform to help people quickly determine the cause of the network outage of the front-end device. Moreover, even if the outdoor wireless device can no longer connect to the Internet in the original working mode, it can still be remotely restarted through the 4G communication network, etc., in order to try to solve the problem of the outdoor wireless device faster and more conveniently.

[0026] In this application, the SIM card is disconnected when there is no problem with the device. This is because: Taking the Internet of Things card as an example, it is automatically activated after being inserted into the device, and is bound to the device after activation. After that, the program in the device can be connected to the corresponding platform through the Internet; if the SIM card is not disconnected during use, it will actually continue to use traffic. Although not much, the number of data items and traffic of the Internet of Things card are very small compared to mobile phone packages. After all, the cost must be considered; moreover, in other embodiments of the present application, in addition to the above-mentioned random code, a larger data interaction is performed through the 4G communication link. Therefore, in this application, the SIM card needs to be disconnected (deactivated) when the device is normal.

[0027] In another embodiment of the present application, the system also includes an audio module, which includes a microphone and a speaker, both of which are electrically connected to the control module. The microphone collects sound and converts it into an electrical signal to the control module; the speaker plays audio according to the output of the control module.

[0028] The control module is configured as: If the time difference t1 is greater than the abnormal trigger threshold T, the real-time audio data collected by the audio module (i.e., microphone) is called and recognized; If the preset wake-up condition (such as the appearance of a wake-up word) appears in the recognition result, a dialogue prompt is issued through the audio module (i.e., the speaker), and the subsequent audio data is sent to the designated platform and receives dialogue feedback from the designated platform.

[0029] According to the above settings, when a network failure occurs in the device, the voice interaction function will be turned on. If someone says a specific wake-up word within the sound range of the microphone, the device will then upload the on-site audio to the designated cloud platform. At this time, if the operator has loaded a matching customer service AI on the cloud platform, it can automatically guide the person at the device location to troubleshoot and repair the device. Even without touching the device, temporary maintenance of the device can be achieved by triggering the maintenance function instructions pre-stored in the designated cloud platform.

[0030] The aforementioned main audio recognition function is not implemented on the device side for the following reasons: First, relatively complex conversations require greater computing power, models, and library support, which is relatively unsuitable for wireless devices; second, when the conversation occurs, the 4G communication link has already been established and is connected to the cloud platform, so it is only necessary to set it to audio upload and analysis for a more accurate conversation; finally, if the question-and-answer model required for the conversation is installed on the device, the device will need to be remotely upgraded from time to time, which will result in greater traffic demand.

[0031] Furthermore, because the device already has the basic hardware for calls, the control module is also configured to: If the preset dialing request information appears in the audio recognition result, the pre-stored service number is called for dialing, or a dialing object filling request is issued through the audio module, and the number is dialed according to the subsequent audio recognition result.

[0032] According to the above settings, in addition to being able to expand into devices that can provide online repair guidance from intelligent customer service, this application can also allow people to directly contact after-sales personnel arranged by the operator through the device to solve various problems through manual after-sales service, which also provides conditions for emergency needs in special scenarios.

[0033] It should be noted that many outdoor wireless devices are currently exposed to the open air on poles, so microphones and speakers should be installed facing downwards and waterproofed to prevent water from entering the equipment and causing malfunctions.

[0034] In another embodiment of the present application, considering the outdoor installation stage, for example, the installation location of the network for a parking lot is relatively low, but if it is a camera pole or a monitoring pole for organic agriculture, the height is relatively high. In this case, if the speaker parameters of all batches of products are the same, the above-mentioned dialogue function will have problems. Therefore, the control module is configured as follows: Get the installation height of the device. It should be understood that the height here refers to the height of the device from the installation surface corresponding to the device installation structure, not the altitude above sea level. The preset height and volume correspondence data is searched according to the installation height, the current volume is determined, and the audio module adjustment parameters (ie, the volume of the speaker) are controlled according to the current volume.

[0035] According to the above settings, when the installation height of the device changes, people below it can still have relatively clear conversations.

[0036] Furthermore, the present application also includes a ranging unit, which may be an ultrasonic ranging sensor or an activation ranging sensor. The ranging unit is electrically connected to the control module, and the controller module is configured as follows: If the time difference t1 is greater than the abnormal trigger threshold T, the distance detection value of the distance measuring unit is read and assigned as the installation height of the equipment.

[0037] With the above setup, the device doesn't require manual input of the installation height; it is automatically determined by the distance measuring unit. To ensure this function is not interfered with, the distance measuring unit's probe should project a detection path from the bottom of the installed device, and the detection path should not be obstructed by any obstacles such as mounting poles or walls.

[0038] In another embodiment of the present application, a wire-reeling mechanism 3 is installed in the device, and the wire-reeling mechanism 3 includes a servo motor 31 and a roller 32. The roller 32 is connected to the open box body by rotating the shaft in the direction of the central axis, and the open box body is screwed into the housing 1 of the device; a gear is fixed on the shaft of the roller 32, the servo motor is fixed to the outer wall of the open box body and the output shaft is fixed to another gear, and the two gears are meshed. The cable corresponding to the microphone is wound around the roller 32, and the housing is provided with a through hole for the microphone to slide down. The servo motor 31 is electrically connected to the control module, and the control module is configured as follows: If the preset wake-up condition appears in the audio recognition result, the retractable wire mechanism 3 is controlled to release the microphone, and the release amount is the installation height of the device. That is, the person only needs to move his hand to the bottom of the ranging unit, or stand under the ranging unit, and the device will control the servo motor 31 to rotate and lower the microphone, making it convenient for the person to communicate with the intelligent customer service and after-sales through the device; after the conversation is completed, the servo motor 31 reverses to let the microphone go back.

[0039] In one embodiment of the present application, the link switching module includes an electronic switch circuit and a relay module. The electronic switch circuit's control terminal is connected to the control module, and its controlled terminal is connected to a relay coil in the relay module. The normally open relay contact of the relay module is connected in series with the UICC receiving unit. The electronic switch circuit, for example, is a transistor switch circuit; the relay module, for example, is a relay coil and a protective capacitor connected in reverse series with the coil. Therefore, the transistor's base is connected to the control module, and the collector is connected in series with the coil.

[0040] In another embodiment of the present application, it is believed that many functions of the present device are based on the SIM card, and the SIM uses the network to generate traffic consumption. However, in this application, it is different from the traditional IoT card. It is difficult to estimate more accurate quarterly and annual traffic based on the application method in advance because it is random. This leads to the fact that if a large traffic package is purchased in advance, the cost will be high when a large number of devices are deployed, and if it is too little, the function may not be used normally.

[0041] Therefore the control module is also configured as: Collect usage statistics of SIM card traffic and compare the statistics with the preset standard values; If the comparison value is less than the preset traffic exhaustion threshold, a traffic exhaustion prompt will be sent to the designated cloud platform and the device ID will be bound.

[0042] According to the above settings, the operator only needs to check the traffic exhaustion prompt section of the cloud platform to find devices with insufficient traffic in advance and plan solutions in advance, so there is no need to pay more expensive service fees for each device at the beginning.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
