Description

Technical Field

[0001] The present application belongs to the field of communication circuit technology, and specifically relates to a low-power 4G network communication control circuit and security equipment. Background Art

[0002] In the current battery-based 4G network communication security equipment such as surveillance cameras, in order to obtain monitoring information in a timely manner, the 4G network communication module and the communication base station need to remain in the network state at all times. Therefore, the power consumption of the 4G network communication module is relatively large, which greatly affects the working time of the entire camera. When encountering continuous rainy weather, solar energy cannot be used for charging, and the camera may not work, resulting in the loss of key information.

[0003] In the prior art, the current conventional practice is to use high-quality, large-capacity batteries to ensure working time, which can maintain a longer working time.

[0004] However, the cost of high-quality, large-capacity batteries is high, and the cost of the supporting solar charging panels will also increase. In addition, large-capacity batteries and high-power solar panels are relatively large in size and weight, making them difficult to install and use, and their use scenarios are limited. Summary of the invention

[0005] In order to solve at least one technical problem existing in the background technology, the present application provides a low-power 4G network communication control circuit, which realizes low-power control of 4G network communication through keep-alive control in sleep state, reduces the size and cost of the battery, improves the scene adaptability of the security equipment, and also improves the overall operating time and reliability of the security equipment.

The control module circuit includes a control chip U20, which is used to manage the power supply and communication between the power chip U9 and the network communication chip U11A, ensuring that the network communication chip U11A can still maintain connection with the base station through the protocol during dormancy, and can be awakened when necessary. The communication between the control chip U20 and the network communication chip U11A enables the network communication chip U11A to periodically send heartbeat packets to the base station even in a dormant state, maintain an online state, and ensure that it can receive instructions or transmit data at any time. When data collection or other tasks are required, the control chip U20 can wake up the network communication chip U11A by communicating with the network communication chip U11A, so that it can resume normal operation from a dormant state, thereby achieving the flexibility of working on demand. In summary, the low-power 4G network communication control circuit provided in the embodiment of the present application significantly improves the operating efficiency and durability of battery-powered 4G network monitoring and security equipment by optimizing power management, maintaining network connection in a dormant state, and providing an intelligent wake-up mechanism. This not only reduces the demand for large-capacity batteries and reduces equipment costs, but also makes the equipment more flexible and convenient in installation and use, especially in environments where solar charging is unreliable, such as continuous rainy weather conditions, it can still reliably perform monitoring tasks.

[0038] like Figures 1 to 3 As shown, the first aspect of the present application provides a low-power 4G network communication control circuit, including:

[0039] A power control circuit, including a power chip U9;

[0040] 4G network communication module circuit, including network communication chip U11A;

[0041] Control module circuit, including control chip U20;

[0042] Among them, the power chip U9 is electrically connected to the network communication chip U11A and the control chip U20, the power control circuit supplies power to the network communication chip U11A through the power chip U9, the power chip U9 is suitable for adjusting the switching frequency when the network communication chip U11A is in a dormant state, and the control module circuit controls the power enable of the power chip U9 through the control chip U20;

[0043] The control chip U20 is electrically connected to the network communication chip U11A. The control chip U20 is suitable for communicating with the network communication chip U11A to control the network communication chip U11A to perform keep-alive communication with the base station in a sleep state.

[0044] The power control circuit includes the power chip U9, which is the key component responsible for power management in the entire circuit. The power chip U9 is not only responsible for supplying power to the network communication chip U11A, but also adjusts its own switching frequency when the network communication chip U11A is in sleep mode, enters the light load high efficiency mode, and thus reduces energy consumption.

[0045] The 4G network communication module circuit includes the network communication chip U11A, which is the core component responsible for data transmission and is also the key part for maintaining communication with the base station. Even when the network communication chip U11A is in sleep mode, it can maintain network connection with the base station.

[0046] The control module circuit includes a control chip U20, whose main responsibility is to manage the power supply between the power chip U9 and the network communication chip U11A, and communicate with the network communication chip U11A through a protocol to ensure that the network communication chip U11A can maintain connection with the base station during sleep and be awakened when necessary.

[0047] According to the low-power 4G network communication control circuit provided by the embodiment of the first aspect of the present application, the power control circuit includes a power chip U9, which is used to provide power support to the network communication chip U11A. The power chip U9 can adjust the switching frequency when the network communication chip U11A is in a dormant state to enter a light-load high-efficiency mode and reduce energy consumption. By allowing the power chip U9 to automatically adjust the switching frequency when the network communication chip U11A enters dormancy, the circuit can still maintain high conversion efficiency under light-load conditions, thereby reducing power consumption and extending battery life. Among them, the network communication chip U11A in the 4G network communication module circuit is the core component responsible for data transmission, and also has the ability to maintain communication with the base station, and can maintain network connection even in a dormant state. The control module circuit includes a control chip U20, which is used to manage the power supply and communication between the power chip U9 and the network communication chip U11A, ensuring that the network communication chip U11A can still maintain connection with the base station through the protocol during dormancy, and can be awakened when necessary. The communication between the control chip U20 and the network communication chip U11A enables the network communication chip U11A to periodically send heartbeat packets to the base station even in a dormant state, maintain an online state, and ensure that it can receive instructions or transmit data at any time. When data collection or other tasks are required, the control chip U20 can wake up the network communication chip U11A by communicating with the network communication chip U11A, so that it can resume normal operation from a dormant state, thereby achieving the flexibility of working on demand. In summary, the low-power 4G network communication control circuit provided in the embodiment of the present application significantly improves the operating efficiency and durability of battery-powered 4G network monitoring and security equipment by optimizing power management, maintaining network connection in a dormant state, and providing an intelligent wake-up mechanism. This not only reduces the demand for large-capacity batteries and reduces equipment costs, but also makes the equipment more flexible and convenient in installation and use, especially in environments where solar charging is unreliable, such as continuous rainy weather conditions, it can still reliably perform monitoring tasks.

[0048] like Figure 1 As shown, in some embodiments of the present application, pin 5 of the power chip U9 is an input pin, and pin 5 is connected to an external power supply battery; pin 4 of the power chip U9 is an enable control pin, and pin 4 is connected to the control chip U20.

[0049] Pin 5 of the power chip U9 is used as an input pin for connecting an external power supply battery, that is, the power chip U9 can receive power input from an external power source (such as a battery). Pin 4 of the power chip U9 is used as an enable control pin and is connected to the control chip U20. In this way, the control chip U20 can control the power chip U9, decide when to turn on or off the power supply, and then control the power consumption of the entire circuit.

[0050] like Figure 1As shown, in some embodiments of the present application, pin 6 of the power chip U9 is an output pin, and pin 6 is connected to the network communication chip U11A. The power chip U9 can adjust its output current and voltage according to the state of the network communication chip U11A to adapt to different working conditions. In particular, when U11A is in a dormant state, the power chip U9 can adjust its switching frequency and enter a light-load high-efficiency mode to reduce energy consumption. When the network communication chip U11A is in a working state, the output pin 6 of the power chip U9 will provide stable power support to ensure that the network communication chip U11A can work normally. When the network communication chip U11A enters a dormant state, the power chip U9 will adjust its output characteristics according to the instructions of the control chip U20 and enter a low-power mode. At this time, the power chip U9 can automatically adjust its switching frequency to reduce unnecessary power loss. This feature allows the power conversion efficiency to be maintained at a high level during the dormancy of the network communication chip U11A, thereby reducing the waste of electricity and extending the service life of the battery.

[0051] Furthermore, if Figure 2 As shown, in some embodiments of the present application, pins 38 and 39 of the network communication chip U11A are power supply pins, and pins 38 and 39 are connected to pin 6 of the power chip U9.

[0052] like Figure 2 As shown, in some embodiments of the present application, pins 123 and 124 of the network communication chip U11A are communication pins, and pins 123 and 124 are connected to the control chip U20. The network communication chip U11A can exchange data with the control chip U20, and the control chip U20 can send instructions to the network communication chip U11A and receive status feedback from the network communication chip U11A. When the network communication chip U11A is in a working state, the control chip U20 can send instructions through pins 123 and 124 to control the network communication chip U11A to perform corresponding actions, such as establishing a network connection, sending data, etc. Similarly, when the network communication chip U11A is in a dormant state, the control chip U20 can still maintain contact with the network communication chip U11A through these two pins and send necessary control instructions, such as letting the network communication chip U11A regularly send heartbeat packets to the base station to maintain a network connection. When the network communication chip U11A needs to be awakened, the control chip U20 can also send a wake-up instruction through the two communication pins to restore the network communication chip U11A from the sleep state to the normal working mode.

[0053] In this way, the control chip U20 can accurately control the working state of the network communication chip U11A, ensuring that it enters a low power consumption mode when frequent data transmission is not required, thereby reducing power consumption and extending the battery life.

[0054] like Figure 2 As shown, in some embodiments of the present application, pin 108 of the network communication chip U11A is an interrupt output pin, and pin 108 is connected to the control chip U20; pin 108 is suitable for transmitting a signal to the control chip U20 when an event occurs to remind the control chip U20 to work. When the network communication chip U11A detects a preset trigger condition, such as receiving a new data packet, detecting an abnormal situation or other information that needs to be processed immediately, pin 108 of the network communication chip U11A will generate an interrupt signal and pass it to the control chip U20. After receiving this interrupt signal, the control chip U20 can immediately wake up from the sleep state and take corresponding measures, such as starting data collection, starting video recording, sending an alarm, etc.

[0055] Through the interrupt mechanism, the system can respond to important events detected by the network communication chip U11A in the first time, ensuring the real-time and effectiveness of the monitoring system. When no event occurs, the system can remain in a dormant state, which greatly reduces power consumption and extends the operating time of the device, especially in battery-powered situations. This is crucial to improving the endurance of the device. For security equipment, timely response means that abnormal situations can be captured quickly and measures can be taken in time, improving the safety and reliability of the system. The interrupt output mechanism enables the system to respond quickly to external events without having to maintain a high power consumption state, increasing the flexibility and adaptability of the device in different application scenarios.

[0056] like Figure 2 As shown, in some embodiments of the present application, pin 109 of the network communication chip U11A is a terminal input pin, and pin 109 is connected to the control chip U20; wherein, when an event occurs, the control chip U20 wakes up the network communication chip U11A through pin 109.

[0057] The specific working principle is:

[0058] Sleep state: When the network communication chip U11A does not need to transmit data, it can enter the sleep state to save power. At this time, the power chip U9 will adjust its switching frequency to further reduce power consumption.

[0059] Event detection: The control chip U20 is responsible for monitoring various events, such as timed wake-up, external sensor triggering, etc. When an event that requires the intervention of the network communication chip U11A is detected, the control chip U20 will prepare to wake up the network communication chip U11A.

[0060] Wake-up signal: Once it is determined that the network communication chip U11A needs to be awakened, the control chip U20 will send a wake-up signal to U11A through pin 109. This signal is usually a specific level change or a pulse signal.

[0061] Wake-up response: When the network communication chip U11A receives the wake-up signal, it will recover from the sleep state to the working state and prepare to perform the specified tasks, such as establishing a network connection, sending or receiving data, etc.

[0062] By managing the sleep and wake-up process of the network communication chip U11A through the control chip U20, the overall power consumption of the system can be significantly reduced, which is particularly critical for devices that rely on battery power and can extend the working time of the device. The control chip U20 can immediately wake up the network communication chip U11A as needed to ensure that a network connection can be quickly established, data can be transmitted or other tasks can be performed when needed, thereby improving the response speed and real-time performance of the system. This design allows the system to flexibly adjust the working mode according to actual conditions, which can save power when not necessary and quickly resume working status when needed, thereby enhancing the adaptability and reliability of the system.

[0063] Assume that in a security monitoring system, when the surveillance camera detects motion, the control chip U20 will wake up the network communication chip U11A through pin 109, so that it can connect to the network and upload the recorded video clips to the server. This not only saves power, but also ensures a quick response in an emergency.

[0064] In summary, by setting pin 109 of the network communication chip U11A as the terminal input pin and connecting it to the control chip U20, the system can effectively manage power consumption without affecting performance, ensuring that the device can respond in time at critical moments.

[0065] like Figure 3 As shown, in some embodiments of the present application, pin 29 of the control chip U20 is a power enable pin, and pin 29 is connected to the power chip U9, wherein when pin 29 is at a high level, the power chip U9 is in a power-maintaining state; pin 26 of the control chip U20 is a power control pin, and pin 26 is connected to an additional power supply, wherein when the network communication chip U11A is in a sleep state, pin 26 is at a low level to turn off the additional power supply, and when the network communication chip U11A wakes up, pin 26 is at a high level to start the additional power supply.

[0066] Specifically, pin 29 is used as a power enable pin to control whether the power chip U9 provides the main power for the network communication chip U11A. When pin 29 is at a high level, it means that the control chip U20 sends an enable signal to the power chip U9, and the power chip U9 is in a power-maintaining state to provide the required power for the network communication chip U11A. When pin 29 is at a low level, it means that the power is turned off, and the network communication chip U11A will lose the main power supply. Pin 26 is used as a power control pin to control the on and off of the additional power supply. When the network communication chip U11A is in a dormant state, the control chip U20 turns off the additional power supply by setting pin 26 to a low level to reduce unnecessary power consumption. When the network communication chip U11A needs to be awakened, the control chip U20 sets pin 26 to a high level, starts the additional power supply, and provides the necessary additional power support for the network communication chip U11A.

[0067] Hibernation:

[0068] When the network communication chip U11A is in sleep mode, the control chip U20 sets pin 29 to a high level to keep the power chip U9 providing basic power to the network communication chip U11A, and sets pin 26 to a low level to cut off the additional power supply, thereby entering low power consumption mode.

[0069] Wake-up state:

[0070] When the network communication chip U11A needs to be awakened, the control chip U20 first keeps pin 29 at a high level to ensure the basic power supply of the network communication chip U11A; then sets pin 26 to a high level to start the additional power supply, so that U11A can wake up from the sleep state and enter the normal working mode.

[0071] By independently controlling the power chip U9 and the additional power supply, the system can fine-tune the power consumption in different working states to achieve high efficiency and energy saving. By reducing the power consumption in the sleep state, the overall operation time of the device can be extended, especially when powered by batteries. When a quick response is required, the system can quickly wake up the network communication chip U11A to ensure the timely transmission of data and improve the reliability of the system. This design allows the system to flexibly adjust the working mode according to actual needs, which can save power when it is not necessary and quickly resume working state when needed, enhancing the adaptability and flexibility of the system.

[0072] like Figure 3As shown, in some embodiments of the present application, pins 30 and 31 of the control chip U20 are connected to the network communication chip U11A, and pins 30 and 31 are suitable for controlling the network communication chip U11A to enter a sleep state and perform keep-alive communication with the base station; pin 27 of the control chip U20 is connected to the network communication chip U11A, and the control chip U20 is suitable for waking up the network communication chip U11A through pin 27.

[0073] Specifically, when the network communication chip U11A does not need to perform data transmission, the control chip U20 can send a signal through pins 30 and 31 to instruct the network communication chip U11A to enter a sleep state. In the sleep state, the network communication chip U11A still needs to maintain a certain communication with the base station to ensure that the network connection is not disconnected due to long-term inactivity. This type of communication is called "keep-alive communication" and is usually manifested as the periodic sending of heartbeat packets. The control chip U20 sends necessary control instructions through pins 30 and 31 to ensure that the network communication chip U11A can maintain a connection with the base station in the sleep state.

[0074] Pin 27 is used as a wake-up pin to wake up the network communication chip U11A. When the network communication chip U11A needs to wake up from the sleep state to perform a specific task (such as data transmission, receiving new instructions, etc.), the control chip U20 sends a wake-up signal through pin 27. After receiving the wake-up signal, the network communication chip U11A will recover from the sleep state to the normal working state and prepare to execute the task assigned by the control chip U20.

[0075] By finely managing the sleep state of the network communication chip U11A through the control chip U20, the power consumption of the device during inactivity can be significantly reduced, thereby extending the device's operating time. Through the keep-alive communication mechanism, the device can maintain connection with the base station even when it is in sleep mode, ensuring the stability of the network and the reliability of data transmission. When a quick response is required, the control chip U20 can quickly wake up the network communication chip U11A through pin 27 to ensure that the device can perform tasks in a timely manner, improving the system's real-time response capabilities. This design allows the device to flexibly switch between different working modes, which can save power when not necessary and quickly resume working status when needed, enhancing the adaptability and reliability of the system.

[0076] A second aspect of the present application provides a security device, comprising the low-power 4G network communication control circuit in any embodiment of the first aspect.

[0077] Security equipment can be battery-powered surveillance cameras, drone cameras, thermal imaging cameras, etc.

[0078] In the field of security monitoring, battery-powered surveillance cameras are often used in places that need to be moved or difficult to wire, such as temporary construction sites, remote areas, temporary event venues, etc. Low-power 4G network communication control circuits can significantly extend the working time of these cameras and reduce the frequency of battery replacement, thereby reducing maintenance costs. In addition, the circuit's intelligent wake-up mechanism ensures that even in sleep mode, it can respond to emergencies in a timely manner and quickly transmit monitoring information to the monitoring center.

[0079] Drone cameras are widely used in agriculture, geographic mapping, disaster relief and other fields. Due to the large operating altitude and range of drones, the battery capacity they carry is limited, so extending the flight time becomes one of the key issues. By adopting low-power 4G network communication control circuit, the drone can enter a dormant state when not working, reducing power consumption, thereby extending the use time after each charge and improving work efficiency.

[0080] Thermal imaging cameras are often used in nighttime surveillance, forest fire monitoring, infrared inspection of buildings, and other scenarios. Since thermal imaging equipment usually needs to run for long periods of time without supervision, reducing power consumption is essential to extend the working time of the equipment. Low-power 4G network communication control circuits can help thermal imaging cameras enter low-power mode during inactive periods while maintaining a network connection with the monitoring center to ensure timely data transmission when necessary.

[0081] By reducing energy consumption during non-essential times, low-power control circuits can significantly extend the operating time of equipment, especially when powered by batteries. By reducing the need for large-capacity batteries, the cost of the equipment is reduced, and the equipment is more flexible and convenient to install and use. In environments where solar charging is unreliable, such as continuous rainy weather conditions, the circuit can still ensure that the equipment can reliably perform monitoring tasks, improving the overall operational reliability and durability of the system. By optimizing power management and providing an intelligent wake-up mechanism, security equipment can not only continue to operate in a variety of environments, but also respond quickly to emergencies, improving the adaptability and flexibility of the equipment.
