[0042] With the continuous development of technology, people's demand for communication is also constantly increasing. Currently, the mature communication system still relies on terrestrial cellular networks. However, some areas in China have poor network signal quality or even no network coverage, thus requiring satellite communication technology to supplement the blind spots of terrestrial cellular network signals. With the full deployment of the BeiDou-3 satellite system, BeiDou satellites are now providing comprehensive navigation and positioning services to domestic industries. In addition to navigation and positioning, BeiDou-3, utilizing GEO (Geostationary Orbit) satellites, can also achieve communication functions.

[0043] See Figure 1 The security monitoring device provided in this application includes: a main controller 301, and a ground cellular communication module 302 and a Beidou short message satellite communication module 303 respectively connected to the main controller 301;

[0044] The main controller 301 is used for:

[0045] When it is determined that the security monitoring equipment needs to transmit data, the ground cellular communication module 302 is controlled to start working, and data is transmitted through the ground cellular communication module 302;

[0046] Detect the signal quality of the terrestrial cellular network currently in which the security monitoring equipment is located;

[0047] When the signal quality of the terrestrial cellular network does not meet the preset data transmission conditions, the BeiDou short message satellite communication module 303 is controlled to start working and data is transmitted through the BeiDou short message satellite communication module 303.

[0048] The security monitoring equipment mentioned above includes surveillance cameras such as PTZ cameras.

[0049] The terrestrial cellular communication module 302 is a functional module used to realize terrestrial cellular communication for local security monitoring equipment.

[0050] The BeiDou short message satellite communication module 303 is a functional module used to realize BeiDou short message satellite communication for local security monitoring equipment.

[0051] The signal quality of the terrestrial cellular network in which the local security monitoring equipment is currently located can be determined, for example, by parameters such as Reference Signal Receiving Power (RSRP) and Channel to Interference Plus Noise Ratio (SINR).

[0052] In some embodiments, see Figure 2 The security monitoring equipment also includes a power supply module 30 connected to the main controller 301;

[0053] The power supply module 30 is used to supply power to the ground cellular communication module 302 and the Beidou short message satellite communication module 303 under the control of the main controller 301.

[0054] In some embodiments, see Figure 3 The power supply module 30 includes a first power supply circuit 304 and a second power supply circuit 305, which are respectively connected to the main controller 301.

[0055] The first power supply circuit 304 is used to supply power to the ground cellular communication module 302;

[0056] The second power supply circuit 305 is used to supply power to the Beidou short message satellite communication module 303.

[0057] In some embodiments, see Figure 4 The first power supply circuit 304 is the first BUCK circuit 304;

[0058] The second power supply circuit 305 is the second BUCK circuit 305.

[0059] The BUCK circuit described in the embodiments of this application is a step-down converter circuit.

[0060] In some embodiments, the main controller 301 controls the enabling of the first BUCK circuit 304 through the first GPOI pin;

[0061] The main controller 301 controls the enabling of the second BUCK circuit 305 through the second GPOI pin.

[0062] In some embodiments, see Figure 5 The ground cellular communication module 302 is connected to the ground cellular communication antenna 306; the Beidou short message satellite communication module 303 is connected to the Beidou short message satellite communication antenna 307.

[0063] In some embodiments, see Figure 5 The security monitoring equipment also includes a camera 300;

[0064] See Figure 6 The camera 300 is a spherical camera 300, and the ground cellular communication antenna 306 is disposed on the side ear of the spherical camera 300;

[0065] The Beidou short message satellite communication antenna 307 is mounted on the top of the spherical camera 300.

[0066] In some embodiments, the BeiDou short message satellite communication antenna 307 is a BeiDou short message satellite communication antenna that supports the BeiDou short message communication frequency band and the navigation and positioning frequency band, wherein the BeiDou short message communication frequency band includes the uplink L band and the downlink S band; the navigation and positioning frequency band includes the B1I band and / or the B1C band.

[0067] For example, see Figure 6 The overall structural layout of the spherical security camera 300 is designed to improve its practicality. A solar panel can be used as an accessory to provide power, addressing environments where cable installation is inconvenient. A BeiDou short message satellite communication antenna 307 is mounted on the top of the device, while a terrestrial cellular communication antenna 306 is mounted on the right side ear. Because short message satellite communication has low receiving sensitivity (approximately -128dBm) and is easily interfered with by strong transmitted signals (approximately 23dBm) from cellular sources, to maximize the spatial distance between the two antennas, ensure their isolation, and effectively prevent mutual coupling, this embodiment places the terrestrial cellular communication antenna 306 on the side ear of the security camera and the BeiDou short message satellite communication antenna 307 on the top. Simultaneously, the BeiDou short message satellite communication antenna 307 is positioned directly opposite the top antenna, effectively improving the quantity and quality of satellite acquisition and ensuring the stability of BeiDou short message satellite communication. The BeiDou short message satellite communication antenna 307 provided in this application embodiment not only supports the BeiDou short message communication frequency bands (uplink L-band, downlink S-band), but also is compatible with navigation and positioning frequency bands (B1I band and B1C band), reducing the number of antennas required and improving the cost-effectiveness of the equipment. The L-band refers to a radio wave band with frequencies between 1 and 2 GHz; the S-band refers to an electromagnetic wave band with frequencies between 2 and 4 GHz. The B1I band is 1561.098 MHz, and the B1C band is 1575.42 MHz.

[0068] In some embodiments, the main controller 301 is connected to the terrestrial cellular communication module 302 via a USB (Universal Serial Bus) interface;

[0069] The main controller 301 is connected to the Beidou short message satellite communication module 303 via a UART (Universal Asynchronous Receiver / Transmitter) interface.

[0070] In some embodiments, the preset data transmission conditions include:

[0071] The reference signal reception power of the terrestrial cellular network where the local security monitoring device is currently located is greater than a first preset threshold; and / or,

[0072] The channel noise ratio of the terrestrial cellular network in which the local security monitoring device is currently located is greater than the second preset threshold.

[0073] The first preset threshold is, for example, -115dBm. Of course, other values ​​can also be set according to actual needs.

[0074] The second preset threshold is, for example, 3dB. Of course, other values ​​can also be set according to actual needs.

[0075] For example, if the main controller 301 in the local security monitoring equipment detects that the RSRP and SINR of the communication signal of the local terrestrial cellular network transmitted back by the terrestrial cellular communication module 302 are both less than the corresponding threshold, it indicates that the signal quality of the terrestrial cellular network provided by the current operator is poor and cannot effectively carry the data transmission task of the PTZ camera. It is necessary to select the Beidou short message satellite communication method for data transmission.

[0076] If the main controller 301 in the local security monitoring equipment detects that the RSRP and SINR of the communication signal of the local terrestrial cellular network transmitted back by the terrestrial cellular communication module 302 are both higher than the corresponding thresholds, it indicates that the signal quality of the terrestrial cellular network provided by the current operator is good and the terrestrial cellular network can be used to transmit data.

[0077] In some embodiments, when the ground cellular communication module 302 of the local security monitoring device starts working, the Beidou short message satellite communication module 303 of the local security monitoring device stops working;

[0078] When the Beidou short message satellite communication module 303 of the local security monitoring equipment starts working, the ground cellular communication module 302 of the local security monitoring equipment stops working.

[0079] In other words, in order to save power consumption of local security monitoring equipment, this application embodiment controls only one module, either the ground cellular communication module 302 or the Beidou short message satellite communication module 303, to work at the same time, while the other module remains off.

[0080] In some embodiments, the terrestrial cellular communication module 302 of the local security monitoring device is controlled to start working in the following manner:

[0081] Control the first GPIOI pin to pull high the enable pin of the first BUCK circuit 304;

[0082] The ground cellular communication module 302 of the local security monitoring equipment can be stopped from working in the following manner:

[0083] Control the first GPOI pin to pull low the enable pin of the first BUCK circuit 304;

[0084] The BeiDou short message satellite communication module 303 of the local security monitoring equipment is activated in the following manner:

[0085] Control the second GPOI pin to pull high the enable pin of the second BUCK circuit 305;

[0086] The BeiDou short message satellite communication module 303 of the local security monitoring equipment can be stopped from working in the following manner:

[0087] Control the second GPOI pin to pull low the enable pin of the second BUCK circuit 305;

[0088] Wherein, the first BUCK circuit 304 is a circuit in the local security monitoring device used to power the terrestrial cellular communication module 302; the first GPOI pin is a pin in the local security monitoring device used to control the first BUCK circuit 304 to be enabled;

[0089] The second BUCK circuit 305 is a circuit in the local security monitoring device used to power the Beidou short message satellite communication module 303; the second GPOI pin is a pin in the local security monitoring device used to control the enabling of the second BUCK circuit 305.

[0090] In some embodiments, data transmission via the terrestrial cellular communication module 302 includes:

[0091] The main controller 301 in the local security monitoring equipment sends the data to be transmitted to the terrestrial cellular communication module 302 through the universal serial bus interface, and then sends the data out through the terrestrial cellular communication antenna 306 connected to the terrestrial cellular communication module 302.

[0092] Data is transmitted via the BeiDou short message satellite communication module 303, including:

[0093] The main controller 301 in the local security monitoring equipment sends the data to be transmitted to the Beidou short message satellite communication module 303 through the universal asynchronous transceiver interface, and then sends the data out through the Beidou short message satellite communication antenna 307 connected to the Beidou short message satellite communication module 303.

[0094] In some embodiments, to further reduce the power consumption of the local security monitoring equipment, the main controller 301 is also configured to:

[0095] If the monitoring data transmission is complete, then the local security monitoring device is put into sleep mode; otherwise:

[0096] The working status of the terrestrial cellular communication module 302 is identified. If the terrestrial cellular communication module 302 is in the working state, the signal quality of the terrestrial cellular network where the local security monitoring device is currently located is continuously detected. If the terrestrial cellular communication module 302 is in the stopped working state, data is continuously transmitted through the Beidou short message satellite communication module 303.

[0097] As can be seen, by monitoring whether data transmission is completed and its subsequent operations, adaptive network switching (i.e., switching between BeiDou short message satellite communication and terrestrial cellular communication) can be achieved, thereby improving the coverage and communication range.

[0098] In summary, in this embodiment, the main controller 301 is a controller used to execute the aforementioned data transmission control method. The main controller 301 controls the enabling of the first BUCK circuit 304 and the second BUCK circuit 305 through the first GPOI and second GPOI pins, respectively, thereby controlling the working state (on or off) of the ground cellular communication module 302 and the BeiDou short message communication module. The first BUCK circuit 304 and the second BUCK circuit 305 are used to supply power to the ground cellular communication module 302 and the BeiDou short message satellite communication module 303, respectively. The main controller 301 interacts with the ground cellular communication module 302 and the BeiDou short message communication module through USB and UART interfaces, respectively. For specific control procedures, please refer to [reference needed]. Figure 7 As shown, it includes:

[0099] S401. Control the local security monitoring equipment to be in sleep mode;

[0100] S402. Determine whether the local security monitoring device needs to transmit data. If yes, proceed to step S403; otherwise, proceed to step S401 to keep the local security monitoring device in sleep mode.

[0101] S403: Control the first GPIO pin to pull high the first BUCK circuit 304 enable pin, so that the ground cellular communication module 302 starts working.

[0102] S404. Determine whether the signal quality of the terrestrial cellular network where the local security monitoring device is currently located is greater than a preset threshold. If yes, proceed to step S408; otherwise, proceed to step S405.

[0103] S405: Control the second GPIO pin to pull high the enable pin of the second BUCK circuit 305, so that the Beidou short message satellite communication module 303 starts working and transmits data; and control the first GPIO pin to pull low the enable pin of the first BUCK circuit 304, so that the ground cellular communication module 302 is turned off.

[0104] S406. Determine whether the data transmission of the local security monitoring device is complete. If yes, proceed to step S401 and continue to keep the local security monitoring device in sleep mode; otherwise, proceed to step S407.

[0105] S407. Determine whether the first GPIO pin is at a high level. If so, proceed to step S404 to determine whether the signal quality of the terrestrial cellular network where the local security monitoring device is located is greater than a preset threshold and proceed with subsequent steps. Otherwise, proceed to step S405 to continue transmitting data through the Beidou short message satellite communication module 303.

[0106] S408: Transmit data through the ground cellular communication module 302; control the second GPIO pin to pull down the enable pin of the second BUCK circuit 305, so that the Beidou short message satellite communication module 303 is turned off;

[0107] After step S408, continue to step S406, that is, determine whether the data transmission of the local security monitoring device is complete, and then execute its subsequent steps.

[0108] In summary, in this embodiment of the application, when the local security monitoring equipment completes its power-on self-test, if there is no data transmission task at present, the main controller 301 is in a sleep state, and the cellular ground communication module and the Beidou short message satellite communication module 303 are both in a closed state, thereby reducing power consumption and increasing the usage time of the local security monitoring equipment.

[0109] When a timed data transmission task is required, the main controller 301 is woken up. Then, the main controller 301 pulls high the enable pin of the first BUCK circuit 304 via the first GPIOI pin, and the terrestrial cellular communication module 302 starts working. The terrestrial cellular communication module 302 further detects the signal quality of the terrestrial cellular network where the local security monitoring equipment is located, and transmits the signal quality data to the main controller 301 via the USB interface. If the network signal quality is greater than a set threshold, the terrestrial cellular communication module 302 is used to transmit data. The main controller 301 then transmits the data via the USB interface. Data is transmitted to the terrestrial cellular communication module 302, and then sent out through the terrestrial cellular communication antenna 306 connected to the terrestrial cellular communication module 302. While the terrestrial cellular communication module 302 is transmitting data, the main controller 301 pulls down the enable pin of the second BUCK circuit 305 through the second GPIOI pin, and the Beidou short message satellite communication module 303 does not work and is in a closed state, thereby reducing power consumption. When the data transmission is completed, the main controller 301 pulls down the enable pin of the first BUCK circuit 304 through the first GPIOI, and finally the entire circuit is in a sleep state.

[0110] If the signal quality of the terrestrial cellular network communication is less than a set threshold, the main controller 301 controls the first GPIOI pin to pull down the enable pin of the first BUCK circuit 304, causing the terrestrial cellular communication module 302 to stop working. Simultaneously, the main controller 301 controls the second GPIOI pin to pull up the enable pin of the second BUCK circuit 305, enabling the BeiDou short message satellite communication module 303 to start working. The main controller 301 transmits data to the BeiDou short message satellite communication module 303 via the UART interface, and finally transmits it out through the BeiDou short message satellite communication antenna 307. When data transmission is complete, the main controller 301 controls the second GPIOI pin to pull down the enable pin of the second BUCK circuit 305, ultimately putting the entire circuit into a sleep state.

[0111] As can be seen, this embodiment of the application achieves free switching of data transmission communication modes based on the signal quality of the local security monitoring equipment's current terrestrial cellular communication. It utilizes GPIO pins to control the BUCK circuit, thereby selecting either terrestrial cellular communication or BeiDou short message satellite communication as the wireless communication method, ensuring communication continuity and avoiding high power consumption issues. Furthermore, the security monitoring PTZ camera in this embodiment does not maintain a real-time operating state; it only operates when there is a need to transmit data, spending most of the time in sleep mode, which helps reduce power consumption and improves the applicability of the equipment. Based on the equipment's on-site environmental conditions, the security monitoring PTZ camera in this embodiment achieves adaptive network switching by comparing with a set threshold, thereby improving the coverage communication range. Therefore, this embodiment of the application can be applied to the field of low-power security PTZ cameras, combining terrestrial cellular communication technology with BeiDou short message satellite communication technology to expand the application scope of security PTZ cameras. Furthermore, by performing different operations based on the current service, such as device sleep mode, terrestrial cellular communication, or BeiDou short message satellite communication, it ensures real-time communication while meeting low-power performance, enabling the equipment to maintain maximum operating time even without power.
