Technical Field
[0001] The present invention belongs to the technical field of monitors, and in particular relates to a monitoring camera with a reserve power supply. Background Art
[0002] Surveillance cameras play a crucial role in modern security systems. Whether in public or private spaces, they are essential tools for maintaining safety and preventing crime. Traditional surveillance camera systems typically rely on indoor power connections for power and use memory cards to store video data. While this approach can meet basic monitoring needs to a certain extent, the limitations of traditional surveillance methods are becoming increasingly apparent as people's demands for security monitoring, especially the growing demand for real-time monitoring and remote dispatch, are becoming increasingly apparent.
[0003] Existing surveillance cameras suffer from several significant shortcomings. First, when a power outage occurs, the surveillance system often becomes paralyzed. Although some cameras are equipped with a backup power supply, the uncertainty of power restoration makes it difficult to ensure that the monitoring function will resume normal operation in a timely manner. Second, the reliance on indoor wiring for power supply limits the device's installation flexibility and increases wiring costs and difficulty. Finally, while using memory cards to store video is simple and direct, it does not support users to remotely observe or schedule monitoring content in real time, which greatly limits the monitoring system's response efficiency in emergency situations.

DETAILED DESCRIPTION
[0027] First of all, it should be noted that in the various described embodiments, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, lateral, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.
[0028] Example 1: A surveillance camera with a reserve power supply, such as Figure 1-Figure 5As shown, it includes a mounting frame 1 and a camera body 2. The mounting frame 1 is a mounting carrier for the surveillance camera. The camera body 2 is mounted on the mounting frame 1. The camera body 2 has a built-in SIM card holder 21, and the camera body 2 is a cellular network camera. It also includes a mounting plate 3 fixedly connected to the rear side of the mounting frame 1. A mounting box 4 is fixedly mounted on the side of the mounting plate 3 facing away from the camera body 2. A UPS power supply 5 (uninterruptible power supply) is installed inside the mounting box 4. The UPS power supply 5 is a reserve power supply for the camera body 2. A terminal block 6 is fixedly connected to one side of the mounting frame 1. The terminal block 6 is electrically connected to the camera body 2. A charging connector 61 is provided at the bottom of the terminal block 6. The charging connector 61 of the terminal block 6 slides and electrically connects to the plug 71 of the power line 7. The power line 7 is used to power the entire surveillance camera. The terminal block 6 is electrically connected to the UPS power supply 5 through the charging line 51. One side of the UPS power supply 5 is an inverter 52. The inverter 52 is used to convert the DC power stored in the UPS power supply 5 into AC power for use by the camera body 2. The inverter 52 of the UPS power supply 5 is electrically connected to a wire 1 53. The wire 1 53 and The terminal blocks 6 are electrically connected through wire 2 54. When the power supply line 7 is normally connected to an external AC power source, the power supply line 7 directly supplies power to the camera body 2. At the same time, the power supply line 7 charges the UPS power supply 5 through the charging line 51 on the terminal block 6, so that the UPS power supply 5 continuously reserves backup power for the camera body 2. Once the AC power supply external to the power supply line 7 is cut off, the inverter 52 of the UPS power supply 5 immediately provides AC power to the camera body 2 on the terminal block 6 through wire 1 53 and wire 2 54, ensuring that the surveillance camera can maintain normal monitoring work for a certain period of time in the event of a sudden power outage. A testing mechanism 8 is provided at the bottom of the terminal block 6. The testing mechanism 8 is used to test whether the UPS power supply 5 is normally supplying power to the camera body 2, thereby ensuring the effectiveness of the reserve power on the monitoring camera. A heat dissipation mechanism 9 for dissipating heat from the UPS power supply 5 is provided on the installation box 4. The heat dissipation mechanism 9 assists the UPS power supply 5 in dissipating heat during use, ensuring the best performance and longest service life of the UPS power supply 5, while effectively reducing the frequency of monitoring noise of the camera body 2 and optimizing the transmission quality of the monitoring image.
[0029] like Figure 1 、 Figure 3 and Figure 5As shown, the test mechanism 8 includes an AC contactor 81 and a time-controlled switch 82. The AC contactor 81 is installed at the bottom of the terminal board 6. The main contacts in the AC contactor 81 are electrically contacted and connected to the charging connector 61 of the terminal board 6 and the plug 71 of the power supply line 7. The terminal board 6 is equipped with a time-controlled switch 82 that adapts to and controls the AC contactor 81. The power input end of the time-controlled switch 82 is electrically connected to the terminal board 6, and the output end of the time-controlled switch 82 is electrically connected to the two ends of the coil of the AC contactor 81 through a wire. The time-controlled switch 82 is pre-set by the user and turned on at a time. When the time-controlled switch 82 is turned on at a time, it will trigger The AC contactor 81 controls the charging connector 61 and the plug 71 to be disconnected at a fixed time, and after the AC contactor 81 has been disconnected for a period of time, the AC contactor 81 can control the charging connector 61 and the plug 71 to be connected again at a fixed time, thereby simulating the situation where the power supply line 7 is powered by the UPS power supply 5 after the power is cut off, thereby testing whether the UPS power supply 5 is normal in supplying power to the camera body 2 in the case of power outage, thereby regularly testing the key indicators such as the response speed and battery life of the UPS power supply 5 to ensure that the UPS power supply 5 can work normally in an emergency and avoid damage to the monitoring equipment due to long-term power outages.
[0030] like Figure 2 and Figure 10 As shown, the UPS power supply 5 is snap-fitted and slidably assembled in the installation box 4. A cover plate 41 is hingedly installed at an opening on one side of the installation box 4. The cover plate 41 is used to protect the UPS power supply 5 inside the installation box 4. The UPS power supply 5 can be quickly installed and disassembled in the installation box 4, thereby facilitating the inspection and maintenance of the UPS power supply 5.
[0031] like Figure 1 、 Figure 6 and Figure 7As shown, the heat dissipation mechanism 9 includes a mounting shell 91 fixedly connected to one side of the mounting plate 3, a plurality of air holes 55 are provided on the circumference of the shell of the UPS power supply 5, a ventilation plate 92 is fixedly installed at the top opening of the shell of the mounting shell 91, and a plurality of ventilation holes are provided in the ventilation plate 92. A first turbofan 93 is fixedly installed on the inner side of the mounting shell 91 corresponding to the ventilation plate 92, an opening adapted to the first turbofan 93 is provided on the top of the mounting box 4, and the first turbofan 93 is directed toward the UPS power supply 5 through the top opening of the mounting box 4, and a second turbofan 94 is fixedly installed on the side of the mounting shell 91 close to the mounting plate 3. The second turbofan 94 There is a certain distance between the mounting box 4 and the mounting plate 3. The side wall of the mounting box 4 is provided with an opening adapted for the second turbofan 94. The second turbofan 94 is directed toward the UPS power supply 5 through the opening on the side wall of the mounting box 4. The first turbofan 93 and the second turbofan 94 are powered by the power supply line 7. The first turbofan 93 and the second turbofan 94 blow air from different directions of the UPS power supply 5 to form a three-dimensional airflow circulation path, which effectively improves the heat dissipation efficiency. The heat generated by the UPS power supply 5 during operation can be quickly carried out of the mounting box 4 by the airflow, so that the UPS power supply 5 is kept within a suitable operating temperature range to ensure its normal operation.
[0032] When using this surveillance camera, the camera body 2 can be connected to the Internet in real time by inserting a SIM card into the SIM card holder 21, thereby improving the stability of the surveillance camera. Under normal power supply conditions, the external AC power supply is electrically connected to the charging connector 61 of the terminal block 6 through the plug 71 of the power supply line 7. The AC current can directly provide the camera body 2 with the power required for operation. At the same time, the power supply line 7 continuously transmits power to the UPS power supply 5 in the installation box 4 through the charging line 51. The battery pack inside the UPS power supply 5 converts the power into DC power and stores it. The inverter 52 of the UPS power supply 5 converts the stored DC power into AC power compatible with the mains power in real time, and maintains circuit connection with the terminal block 6 through wire one 53 and wire two 54, preparing for emergency power supply. At this time, the first turbofan 93 and the second turbofan 94 are directly powered by the power supply line 7. The first turbofan 93 blows air downward through the ventilation plate 92 on the top of the installation shell 91. The air flow penetrates the air vents 55 of the UPS power supply 5 shell, taking away the heat generated by the internal components. The second turbofan 94 blows air from the side wall of the installation box 4. The opening draws in external air, forming a two-way circulating airflow, ensuring that the UPS power supply 5 maintains a stable temperature during the charging process. The three-dimensional airflow circulation path through the heat dissipation mechanism 9 can effectively reduce the thermal noise of the camera body 2, significantly improve the image clarity in low-light environments, and optimize the transmission quality of the monitoring image. If it is necessary to verify the emergency function of the UPS power supply 5, the user first sets the time to trigger the AC contactor 81 on the time control switch 82 in advance. During normal use of the monitoring camera, the time control switch 82 is used to control the charging connector 61 and the plug 71 at the AC contactor 81 to be disconnected, thereby simulating the external power interruption scenario. At this time, the inverter 52 of the UPS power supply 5 instantly outputs AC power to the terminal block 6 through the wire 1 53 and the wire 2 54, providing seamless power to the camera body 2, verifying the response capability of the emergency circuit. After the test is completed, the time control switch 8 can trigger the AC contactor 81 again to control the electrical connector 61 and the plug 71 to be connected, thereby regularly testing the response speed, battery life and other key indicators of the UPS power supply 5, thereby effectively extending the service life of the UPS power supply 5.
[0033] Example 2: Based on Example 1, Figure 1 、 Figure 6 and Figure 7As shown, a power-off mechanism 10 for controlling the power-off of the heat dissipation mechanism 9 is provided on the outer side of the installation box 4 near the installation plate 3. The power-off mechanism 10 includes a fixed plate 101 fixedly connected to the outer wall of the installation box 4. A power-off switch 102 is fixedly mounted on the fixed plate 101. The connection terminals of the power-off switch 102 are electrically connected in series with the first turbofan 93 and the second turbofan 94 through the connecting line 103. A timer 104 is installed on the fixed plate 101. The timer 104 is electrically connected to the power-off switch 102. The timer 104 is used to time the passage and opening of the power-off switch 102. The timer 104 is electrically connected to the wire 1 53 through the connecting line 2 105. When the power outage camera body 2 is powered by the wire 1 53 and the wire 2 54 from the UPS power supply 5, the current of the wire 1 53 will At the same time, the timer 104 and the power-off switch 102 are connected through the connecting line 2 105. The current will flow through the power-off switch 102 and the connecting line 1 103 and then supply power to the first turbofan 93 and the second turbofan 94, so that the power supply of the first turbofan 93 and the second turbofan 94 can dissipate heat for the UPS power supply 5. The timer 104 starts timing after being powered on. The timer 104 presets a certain proportion of the normal discharge time of the UPS power supply 5. When the UPS power supply 5 supplies power to the camera body 2 for a long time, resulting in low power, the timer 104 reaches the preset time and triggers the power-off switch 102 to open the circuit, thereby disconnecting the first turbofan 93 and the second turbofan 94 from the power supply of the UPS power supply 5, saving the power supply of the UPS power supply 5 and extending the power supply time for the camera body 2.
[0034] like Figure 8 and Figure 9 As shown, a first temperature sensor 11 is provided at the bottom of the terminal board 6, and an electric heater 12 is provided near the timer 104 of the terminal board 6. The electric heater 12 will slowly heat up after being energized. The temperature sensing element of the first temperature sensor 11 is in contact with the heat-conducting shell of the electric heater 12. The first temperature sensor 11 is used to trigger the AC contactor 81. The electric heater 12 is electrically connected to the connecting wire 2 105 through the wire 3 13. When the camera body 2 that is powered off is powered by the UPS power supply 5, the current on the wire 1 53 flows into the electric heater 12 through the connecting wire 2 105 and the wire 3 13. The electric heater 12 will be powered on and slowly heat up. At the same time, the first temperature sensor 11 will synchronously sense the temperature on the electric heater 12. When the first temperature sensor 11 senses that the temperature of the electric heater 12 reaches a preset value after a period of time, the first temperature sensor 11 will automatically trigger the AC contactor 81 through an electrical signal. The plug 71 of the power supply line 7 and the charging connector 61 of the terminal block 6 are disconnected by the AC contactor 81 and can be closed in real time after the test. After the power outage is restored, the camera body 2 and the UPS power supply 5 can be restored to power supply by the power supply line 7 in time, thereby improving the effectiveness of the test function.
[0035] like Figure 7 and Figure 10As shown, an electric heating plate 14 is installed above the ventilation plate 92 of the mounting shell 91, and the electric heating plate 14 is powered by the UPS power supply 5. A second temperature sensor 15 is installed on the inner wall of the mounting box 4. The second temperature sensor 15 is used to control the electric heating plate 14 and the first turbofan 93. When the second temperature sensor 15 senses that the UPS power supply 5 is in a low temperature condition, the second temperature sensor 15 can control the electric heating plate 14 and the first turbofan 93 to be enabled, so that the first turbofan 93 can blow appropriate hot air into the mounting box 4, so that the UPS power supply 5 can maintain operation under suitable temperature conditions, thereby extending the service life of the UPS power supply 5, and through the coordinated work of the second temperature sensor 15 and the electric heating plate 14, the startup time of the UPS power supply 5 in extreme environments is effectively shortened, and the self-discharge rate of the UPS power supply can be reduced. This low-temperature adaptability optimization can ensure the reliability of the monitoring system in cold northern regions, and can also reduce the failure rate of equipment in high-altitude low-temperature environments.
[0036] When a power outage causes a sudden interruption of the external AC power supply of the power supply line 7, the inverter 52 of the UPS power supply 5 immediately transmits the converted AC power to the terminal block 6 through the wire 1 53 and the wire 2 54 to ensure that the camera body 2 continues to operate. At this time, the current on the wire 1 53 activates the timer 104 of the power-off mechanism 10 through the connecting wire 2 105. The timer 104 begins to accumulate the discharge time of the UPS power supply 5. At this time, the first turbo fan 93 and the second turbo fan 94 are powered by the UPS power supply 5, and continue to maintain a two-way heat dissipation airflow to prevent the UPS power supply 5 from overheating due to high-load discharge. When the timer 104 reaches a preset threshold (corresponding to the critical point of the remaining power of the UPS power supply 5), the timer 104 triggers the power-off switch 102 to cut off the circuit of the connecting wire 1 103, and the first turbo fan 93 and the second turbo fan 94 stop running to reduce power consumption and extend the emergency power supply time of the camera body 2. At the same time, the electric heater 12 at the bottom of the terminal block 6 is connected to the wire 3 13 It receives the current of the UPS power supply 5 and gradually heats up. At the same time, the first temperature sensor 11 monitors the outer shell temperature of the electric heater 12 in real time. When the temperature monitored by the first temperature sensor 11 reaches the preset value, the first temperature sensor 11 directly sends a signal to the AC contactor 81. The AC contactor 81 can effectively connect the charging connector 61 and the plug 71 after testing after power failure, ensuring that the system can switch to the normal power supply mode in time after the mains power is restored, avoiding the inability to effectively control the power supply line 7 to restore power when the AC contactor 81 fails, and providing the effectiveness of the UPS power supply 5 test function; if the second temperature sensor 15 in the installation box 4 detects that the ambient temperature is too low, the second temperature sensor 15 automatically starts the electric heating plate 14 for heating, and controls the first turbofan 93 to send hot air into the installation box 4 through the ventilation plate 92, preventing the UPS power supply 5 from performing at low temperatures, and ensuring that the UPS power supply 5 can still output stably in a low temperature environment, thereby improving the ability of the UPS power supply 5 to adapt to different environments.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
