[0031] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work should fall within the scope of protection of the present application.

[0032] The terms "include", "comprise" and other any variants thereof in the specification and claims of the present application and the above-mentioned accompanying drawings refer to "including but not limited to", and are intended to cover non-exclusive inclusion, and are not limited to the examples listed in the text. In addition, the terms "first" and "second" and the like are used to distinguish different objects, rather than to describe a specific order.

[0033] The implementation of the present application will be described in detail below in combination with specific accompanying drawings:

[0034] Figure 1 Fig. 1 is a structural schematic diagram of an Internet of Things terminal according to an embodiment of the present disclosure. Figure 1 The Internet of Things terminal comprises an energy storage module, a photovoltaic module, a power supply module, a video monitoring module, a control module and a wireless communication module. The first end of the power supply module is used to connect to the mains, the second end of the power supply module is connected to the energy storage module, the third end of the power supply module is connected to the photovoltaic module, and the fourth end of the power supply module is connected to the power supply end of the video monitoring module. The video monitoring module is configured to monitor road condition information, and the output end of the video monitoring module is connected to the control module. The control module is in communication connection with the monitoring platform through the wireless communication module.

[0035] In the present embodiment, the video monitoring module is used to monitor road condition information, and various related data such as road condition pictures and vehicle passing conditions are captured through devices such as cameras, and these data are output to the control module in the form of electrical signals. The control module is used to receive the information about the road condition output from the video monitoring module, and to arrange the received video monitoring data according to a certain format or protocol, and then to send to the monitoring platform through the wireless communication module.

[0036] The photovoltaic module can be a photovoltaic panel, and the photovoltaic module is used to convert solar energy into electric energy. When the light intensity meets the demand during the day, the electric energy generated by the photovoltaic module can be directly used as a power supply to provide working power for the video monitoring module to ensure normal operation to monitor the road conditions. In addition, the excess electric energy generated by the photovoltaic module can also be used to charge the energy storage module to store the electric energy for subsequent use in the case of insufficient light, for example, on sunny days with sufficient sunlight, the photovoltaic panel continuously generates electric energy, and at this time, the electric energy required by the video monitoring module is preferentially supplied by the photovoltaic module, and the excess electric energy is slowly charged into the storage battery for storage.

[0037] The energy storage module can be a super capacitor or a storage battery, and the photovoltaic module can charge the energy storage module. When the light intensity cannot meet the power supply demand at night or in rainy weather, the power supply module can select the energy storage module to provide working power for the video monitoring module. For example, there is no sunlight at night, and the photovoltaic module cannot generate electricity. At this time, the previously stored electric energy in the energy storage module can be released to transmit the electric energy to the video monitoring module through the power supply module, so that the video monitoring module can continue to monitor the road conditions and maintain the function of the entire Internet of Things terminal.

[0038] When the light intensity cannot meet the power supply demand and the electric energy in the energy storage module is depleted, the power supply module can select the mains as the last power supply guarantee to provide working power for the video monitoring module to ensure uninterrupted operation of the video monitoring module. At the same time, the mains can also be used to charge the energy storage module to avoid a monitoring blank period and ensure that the road conditions can be continuously monitored and transmitted to the monitoring platform.

[0039] As can be seen from the above, the embodiment can fully utilize solar energy, a clean energy, to generate electricity by integrating the photovoltaic module, reduce the dependence on traditional mains, reduce energy consumption costs, and contribute to environmental protection. When the light is good during the day, the photovoltaic module can supply power for the video monitoring module to ensure smooth development of the road condition monitoring work, and charge the energy storage module to store the excess electric energy. The existence of the energy storage module effectively deals with the case of insufficient light at night, rainy weather, etc. to ensure that the video monitoring module can still operate continuously when there is no sunlight or the photovoltaic power supply is insufficient, realize uninterrupted monitoring of the road conditions, avoid a monitoring blank period, and greatly improve the reliability and stability of the monitoring. The control module and the wireless communication module cooperate to timely transmit the road condition information obtained by the video monitoring module to the monitoring platform, so that the relevant departments can remotely and real-timely master the road condition dynamics to make decisions such as traffic diversion and accident handling, improve the efficiency and accuracy of traffic management, and ensure road traffic safety and smoothness.

[0040] For example, Figure 2As shown, in an embodiment of the present disclosure, the power supply module comprises: a voltage stabilizing tube D1, a switch tube Q2, an OR gate U1, a relay K1, a resistor R1, a resistor R3 and a triode Q1; the photovoltaic module is connected to the first input end of the OR gate U1, the cathode of the voltage stabilizing tube D1 and the first normally open end of the relay K1 respectively, the anode of the voltage stabilizing tube D1 is connected to the control end of the switch tube Q2, the first end of the switch tube Q2 is connected to the energy storage module, the second end of the switch tube Q2 is connected to the second input end of the OR gate U1 and the second normally open end of the relay K1 respectively; the first input end of the relay K1 is connected to the output end of the OR gate U1, the second input end of the relay K1 is grounded, the first normally closed end of the relay K1 is used for connecting the mains, the first common end of the relay K1 is connected to the second common end of the relay K1; the first end of the resistor R1 is connected to the first common end of the relay K1, the second end of the resistor R1 is grounded through the resistor R3, the second end of the resistor R1 is connected to the base of the triode Q1, the collector of the triode Q1 is connected to the first end of the resistor R1, and the emitter of the triode Q1 is connected to the power supply end of the video monitoring module.

[0041] In the embodiment, the power supply module preferentially selects the photovoltaic module for power supply; when the photovoltaic module cannot meet the power supply demand of the video monitoring module, the energy storage module is selected; when the photovoltaic module and the energy storage module cannot meet the power supply demand of the video monitoring module, the mains is selected to provide the power supply voltage.

[0042] Specifically, when the illumination intensity meets the power supply demand, the voltage output by the photovoltaic module is greater than the stable voltage of the voltage stabilizing tube D1, the voltage stabilizing tube D1 is broken down and turned on, the switch tube Q2 can be a P-channel field effect tube, when the voltage stabilizing tube D1 is turned on, the switch tube Q2 is cut off, therefore, the first input end of the OR gate U1 is high, the second input end of the OR gate U1 is low, the OR gate U1 outputs high, the relay K1 is energized and attracted, the first common end of the relay K1 is connected to the photovoltaic module, after being divided by the resistor R1 and the resistor R3, the base of the triode Q1 is high, the triode Q1 is turned on, and the triode Q1 works in a switching state, that is, the voltage output by the photovoltaic module is added to the power supply end of the video monitoring module after passing through the triode Q1.

[0043] When the illumination intensity cannot meet the power supply demand, the voltage output by the photovoltaic module is lower than the stable voltage of the voltage stabilizing tube D1, the voltage stabilizing tube D1 is cut off, and the switch tube Q2 is turned on, at this time, the first input end of the OR gate U1 can be understood as low, the second input end of the OR gate U1 can be understood as high, the OR gate U1 still outputs high, and the relay K1 maintains the attracted state, at this time, the voltage output by the energy storage module is added to the power supply end of the video monitoring module after passing through the switch tube Q2 and the triode Q1 once.

[0044] When the power supply requirements of the video monitoring module cannot be met by both the photovoltaic module and the energy storage module, or the two inputs of the OR gate U1 are both low, the output of the OR gate U1 is low, and the relay K1 is powered off, that is, the first common terminal and the second common terminal of the relay are disconnected from the first normally open terminal and the second normally open terminal of the relay K1, and at this time the video monitoring module is powered by the mains.

[0045] From the above, it can be concluded that the embodiment can automatically switch the power supply source according to the lighting conditions and the power supply capacity, preferentially use the photovoltaic module for power supply, fully utilize solar energy as a clean energy source, reduce the consumption of mains power, and reduce energy consumption costs and environmental pollution. Secondly, through the combination of the voltage stabilizing tube D1, the switching tube Q2, and the OR gate U1 and other elements, the automation and precision control of the photovoltaic and energy storage module power supply switching are realized, the stability and continuity of the power supply are ensured, the power supply interruption of the video monitoring module caused by power supply switching is effectively avoided, and the continuous operation of important functions such as road condition monitoring is ensured. By using resistance voltage division and the switching action of the transistor, each power supply can adapt to the power supply requirements of the video monitoring module, improving the reliability and practicality of the entire Internet of Things terminal, and providing a solid power supply foundation for intelligent traffic and related application scenarios.

[0046] As shown in Figure 2 In an embodiment of the present disclosure, the power supply module further comprises: a voltage stabilizing tube D2; the cathode of the voltage stabilizing tube D2 is connected to the base of the transistor Q1, and the anode of the voltage stabilizing tube D2 is grounded.

[0047] In the embodiment, when a voltage is applied to the base of the transistor Q1, the voltage stabilizing tube D2 plays a role in stabilizing and limiting the amplitude. During normal power supply, the voltage stabilizing tube D2 can prevent the base voltage of the transistor Q1 from being too high and damaging the transistor Q1, ensuring that the transistor Q1 can stably work in the switching state, thereby stably transmitting the voltage of the selected power supply to the video monitoring module and ensuring the safety and reliability of the power supply.

[0048] As shown in Figure 2 In an embodiment of the present disclosure, the power supply module further comprises: a first voltage processing module and a second voltage processing module; the first input terminal of the first voltage processing module is used to connect the mains, the first output terminal of the first voltage processing module is connected to the first normally closed terminal of the relay K1; the second input terminal of the first voltage processing module is connected to the energy storage module, and the second output terminal of the first voltage processing module is connected to the first terminal of the switching tube Q2; the third input terminal of the first voltage processing module is connected to the photovoltaic module, and the third output terminal of the first voltage processing module is connected to the first input terminal of the second voltage processing module, the cathode of the voltage stabilizing tube D1, and the first normally open terminal of the relay K1, respectively; the first output terminal of the second voltage processing module is connected to the first input terminal of the OR gate U1, the second input terminal of the second voltage processing module is connected to the second terminal of the switching tube Q2, and the second output terminal of the second voltage processing module is connected to the second input terminal of the OR gate U1.

[0049] In this embodiment, the video surveillance module operates on DC power, while the AC mains power is AC power. Therefore, AC mains power cannot directly provide a suitable power source for the video surveillance module. The voltage output by the photovoltaic module varies with the intensity of sunlight; directly powering the video surveillance module with this voltage would cause instability in its operating voltage, affecting its operational stability. Similarly, the energy storage module typically outputs a lower voltage, which would also impact the stable operation of the video surveillance module. Therefore, this embodiment includes a first voltage processing module and a second voltage processing module.

[0050] For AC mains power, since it is alternating current and cannot directly meet the DC operating voltage requirements of the video surveillance module, the first voltage processing module can convert the AC mains power into a suitable form and output it to the first normally closed terminal of relay K1 to power subsequent circuits under certain conditions. For energy storage modules, whose output voltage is usually low, the first voltage processing module can boost the voltage and connect it to the first terminal of switching transistor Q2 to ensure effective participation in the power supply switching process. For photovoltaic modules, the first voltage processing module can initially regulate their unstable output voltage that varies with light intensity and output it in three ways: one is connected to the cathode of Zener diode D1 for control logic judgment, one is connected to the first input terminal of the second voltage processing module, and the other is connected to the first normally open terminal of relay K1.

[0051] The second voltage processing module further processes the voltages from the photovoltaic module and the switching transistor Q2. The processed voltages are input to the two inputs of the OR gate U1, providing a stable and appropriate voltage signal basis for the power supply switching logic. This allows the OR gate U1 to output corresponding level signals to control the activation and deactivation of the relay K1 according to different power supply conditions. Ultimately, this achieves the previously mentioned strategy of prioritizing power supply from the photovoltaic module, switching to the energy storage module when photovoltaic power is insufficient, and automatically adapting the mains power to the working voltage requirements of the video monitoring module when both are insufficient. This ensures the stable operation of the video monitoring module and avoids malfunctions caused by voltage instability.

[0052] like Figure 1 As shown, in one embodiment of this disclosure, it further includes: a power supply detection module; the power supply detection module is used to detect the voltage of the mains power, the energy storage module and the photovoltaic module respectively, and the power supply detection module is connected to the control module.

[0053] In the embodiment, the power supply detection module can detect the voltage of the mains, the energy storage module and the photovoltaic module in real time respectively. The detected voltage signals are sent to the control module, and the control module can send the detected voltage signals to the monitoring platform through the wireless communication module. The working status of the power supply module can be viewed in real time by the staff on the monitoring platform. On the one hand, the working status of the current power supply module can be determined according to the received voltage information, so as to make a reasonable decision when the power supply is switched. For example, if the voltage of the photovoltaic module is too low, whether to switch to mains power supply or adjust the discharge strategy of the energy storage module is determined in combination with the voltage of the energy storage module. On the other hand, the control module transmits the voltage signals to the monitoring platform through the wireless communication module. The staff of the monitoring platform can intuitively understand the real-time working status of the power supply module, including whether the mains is stable, the remaining capacity of the energy storage module and the power generation efficiency of the photovoltaic module. This helps the staff to predict possible power problems in advance, arrange maintenance or adjustment in time, and ensure the continuous and stable operation of the entire Internet of Things terminal.

[0054] As shown in Figure 3 In an embodiment of the present disclosure, a selection module and a charging module are further included. The first end of the selection module is connected to the first output end of the first voltage processing module, the second end of the selection module is connected to the photovoltaic module, and the third end of the selection module is connected to the energy storage module through the charging module.

[0055] In the embodiment, the first end of the selection module is connected to the first output end of the first voltage processing module for receiving the electric energy after preliminary processing, and the second end is directly connected to the photovoltaic module for real-time acquisition of the electric energy converted from solar energy. Under sufficient light conditions, the selection module can preferentially select the electric energy output by the photovoltaic module and guide it to the charging module through the third end. The charging module can efficiently charge the energy storage module with electric energy for future use. Such a design not only ensures that the photovoltaic module can maximize charging of the energy storage module at the peak of power generation efficiency, but also realizes the goal of maximum utilization of energy and energy saving and emission reduction through intelligent energy distribution.

[0056] As can be seen from the above, the selection module can flexibly acquire electric energy from different sources, preferentially introduce photovoltaic electric energy when the light is sufficient, and store it in the energy storage module through the charging module, thereby fully utilizing solar energy resources, reducing dependence on mains power, and reducing energy consumption costs and carbon emissions.

[0057] As shown in Figure 4As shown, in an embodiment of the present disclosure, the selection module comprises a Zener D3, a triode Q3 and a triode Q4; the cathode of the Zener D3 is connected to the photovoltaic module, the anode of the Zener D3 is connected to the base of the triode Q3, the base of the triode Q3 is connected to the base of the triode Q4, the collector of the triode Q4 is connected to the photovoltaic module, the emitter of the triode Q4 is connected to the collector of the triode Q3, the emitter of the triode Q3 is connected to the first output of the first voltage processing module, and the collector of the triode Q3 is connected to the charging module.

[0058] In the embodiment, both the commercial power and the photovoltaic module can charge the energy storage module. In order to save electric energy, when the voltage of the photovoltaic module is sufficient, the voltage output by the photovoltaic module is used to charge the energy storage module.

[0059] In the embodiment, the triode Q3 can be a PNP triode, and the triode Q4 can be an NPN triode. When the voltage output by the photovoltaic module is sufficient, the voltage output by the photovoltaic module is greater than the voltage of the Zener D3, the Zener D3 is broken down and turned on, at this time, the triode Q3 is cut off, and the triode Q4 is turned on. The triode Q3 and the triode Q4 both work in an amplification state. When the triode Q4 is turned on, the voltage output by the photovoltaic module passes through the triode Q4 and then passes through the charging module to charge the energy storage module.

[0060] When the light intensity of the environment is weak, and the voltage output by the photovoltaic module cannot meet the working requirement, the Zener D3 is cut off, the triode Q4 is cut off, and the triode Q3 is turned on. At this time, the commercial power processed by the first voltage processing module can be used to charge the energy storage module.

[0061] The charging module can ensure that the photovoltaic electric energy is stored in the energy storage module in a suitable manner, ensure the effective supplement of the energy storage module, and avoid overcharging of the energy storage module.

[0062] As can be seen from the above, the embodiment can automatically select a charging power source, preferentially use the photovoltaic module to charge the energy storage module when the light is sufficient, fully utilize clean energy, and effectively save commercial power resources. Secondly, through the cooperative work of the Zener D3 and the triodes Q3 and Q4, the charging mode can be automatically switched according to the light intensity, and the energy storage module can be ensured to be charged under different light conditions.

[0063] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than limit them. Although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features.
