[0029] With the increasing demand for security monitoring, outdoor pan-tilt cameras are widely used in various locations, such as city streets, industrial parks, and residential areas, for real-time monitoring of specific areas. However, in winter, natural disasters such as freezing rain occur frequently, and outdoor temperatures often drop below zero.
[0030] Existing outdoor omnidirectional surveillance cameras risk freezing and malfunctioning due to their rotating components being exposed to low temperatures. If the camera stops rotating, blind spots will appear, severely impacting its monitoring function and preventing the timely acquisition of complete surveillance footage, potentially negatively affecting security operations. Current solutions involve manual intervention, such as dispatching personnel to manually de-ice, inspect, and maintain the cameras during low temperatures. This approach is not only inefficient and costly but also lacks timeliness.
[0031] Therefore, this utility model proposes a heating device and a monitoring machine, aiming to solve the technical problem that existing outdoor oscillating monitoring machines cannot rotate normally because their rotating parts are exposed to low temperature environments and become frozen.
[0032] In one embodiment of this utility model, reference is made to Figure 1 The heating device is applied to a monitoring machine, which includes a rotating assembly 40 and a monitoring machine body. The rotating assembly 40 is drively connected to the monitoring machine body. The heating device includes:
[0033] Main control circuit 10;
[0034] Temperature detection component 20 is used to detect the first temperature of its own environment and output a corresponding temperature detection signal. The output terminal of the temperature detection component 20 is electrically connected to the main control circuit 10. The main control circuit 10 is used to determine the first temperature based on the temperature detection signal.
[0035] Heating component 30 is disposed on the rotating component 40 and is electrically connected to the main control circuit 10;
[0036] The main control circuit 10 is used to control the heating component 30 to heat the rotating component 40 when the first temperature is lower than a preset threshold.
[0037] In this embodiment, optionally, the temperature detection component 20 can be implemented using a voltage divider circuit composed of a thermistor and a voltage divider resistor. The first end of the voltage divider resistor is connected to the power supply, the second end of the voltage divider resistor is connected to the first end of the thermistor, the second end of the thermistor is grounded, and the intermediate node between the thermistor and the voltage divider resistor is the output terminal of the voltage divider circuit. The main control circuit 10 is electrically connected to the output terminal of the voltage divider circuit, and the voltage output by the output terminal of the voltage divider circuit is the voltage of the thermistor. The main control circuit 10 determines the first temperature of its environment based on the digital signal obtained after performing analog-to-digital conversion on the voltage of the thermistor.
[0038] Optionally, the temperature sensing component 20 can also be implemented using a digital temperature sensor. Digital temperature sensors typically have a built-in ADC (analog-to-digital converter) and necessary signal processing logic, which can directly output a digital signal corresponding to the temperature, simplifying integration with microcontrollers or other digital systems (e.g., analog-to-digital converters). Furthermore, compared to thermistors, digital temperature sensors generally offer higher measurement accuracy, and the relationship between their output signal and temperature is almost perfectly linear, allowing the digital temperature sensor to maintain consistent accuracy over a wide temperature range without requiring additional calibration or compensation circuitry. Therefore, implementing the temperature sensing component 20 using a digital temperature sensor is a preferred embodiment.
[0039] In this embodiment, reference Figure 2 The rotating assembly 40 includes a motor 41 and a transmission mechanism 42. The output shaft of the motor 41 is connected to the first end of the transmission mechanism 42, and the second end of the transmission mechanism 42 is connected to the monitoring unit body via a coupling. The output shaft of the motor 41 and the monitoring unit body are respectively connected to the first and second ends of the transmission mechanism 42 via couplings, ensuring no relative sliding between the transmission mechanism 42, the motor 41, and the monitoring unit body, thus achieving efficient force transmission. The transmission mechanism 42 is responsible for transmitting the rotational motion generated by the motor 41 to the monitoring unit body, enabling the monitoring unit body to rotate.
[0040] Furthermore, to prevent moisture from entering the connection between the transmission mechanism 42 and the motor 41, and the connection between the transmission mechanism 42 and the monitoring unit, which could cause the connection between the transmission mechanism 42 and the motor 41 and the monitoring unit to freeze easily at low temperatures, a sealing design can be implemented at the connection between the transmission mechanism 42 and the motor 41, and the connection between the transmission mechanism 42 and the monitoring unit. For example, a double-lip seal or a waterproof gasket can be installed at the connection to prevent moisture from entering the connection between the transmission mechanism 42 and the motor 41 and the monitoring unit.
[0041] In this embodiment, the heating component 30 can be implemented using a heating wire, heating plate, PTC heater, or silicone heating plate. The heating component 30 is mounted on the rotating component 40 by wrapping or attaching it to ensure that heat can be conducted to the rotating component 40 to the maximum extent when the temperature is below a preset threshold, preventing the rotating component 40 from freezing and failing to rotate normally. For example, when the rotating component 40 includes a motor 41 and a transmission component, lubricating oil is usually used inside the motor 41 to reduce friction between bearings and other moving parts. However, at extremely low temperatures, the lubricating oil may thicken or even freeze, causing difficulty in starting the motor 41 or a decrease in efficiency. To address this, the heating component 30 can be implemented using an electric heating wire, which is wrapped around the outer casing of the motor 41 to ensure that the heat from the electric heating wire can be conducted to the motor 41 to the maximum extent, so that the lubricating oil is within a suitable operating temperature range when the ambient temperature is below the preset threshold, ensuring smooth starting and operation of the motor 41. For example, at extremely low temperatures, especially when there is humidity in the environment, the connecting parts (such as couplings, bearings, etc.) between the transmission mechanism 42 and the output shaft of the motor 41 and / or the monitoring unit may freeze due to condensation. To address this, the heating assembly 30 can be implemented using a heating element. By covering the connection between the output shaft of the motor 41 and the transmission mechanism 42 and / or the connection between the transmission mechanism 42 and the monitoring unit, the heating element ensures that when the temperature is below a preset threshold, it can maximize heat transfer to the connection between the output shaft of the motor 41 and the transmission mechanism 42, and / or the connection between the transmission mechanism 42 and the monitoring unit.
[0042] In this embodiment, the main control circuit 10 can be implemented using a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or a SOC (System On Chip).
[0043] This utility model's heating device includes a main control circuit 10 and a temperature detection component 20. The temperature detection component 20 detects the first temperature of its surrounding environment and outputs a corresponding temperature detection signal. The output terminal of the temperature detection component 20 is electrically connected to the main control circuit 10. A heating component 30 is mounted on a rotating component 40 and is electrically connected to the main control circuit 10. The main control circuit 10 determines the first temperature based on the temperature detection signal and controls the heating component 30 to heat the rotating component 40 when the first temperature is lower than a preset threshold. In practical applications, this heating device effectively prevents the rotating component 40 of the monitoring unit from freezing due to low temperatures, ensuring normal operation of the monitoring unit even in cold weather. This allows users to obtain more continuous and complete monitoring images, unaffected by ambient temperature, enhancing the effectiveness of the security system and improving the user experience. Compared to existing manual intervention methods, this utility model automatically controls the heating component to heat the rotating component when the ambient temperature is lower than a preset threshold, improving the reliability of the monitoring unit. It eliminates the need for regular inspection and maintenance by personnel, reducing labor costs and time investment. Furthermore, since the main control circuit, temperature detection component, and heating component of this utility model can all adopt modular design, the structure of the heating device of this utility model is relatively simple and has good implementability and compatibility. This allows existing monitoring machines to be installed with the heating device of this utility model without significant modifications, thereby saving material costs and shortening the design cycle.
[0044] In relatively dry environments, when the ambient temperature is below a preset threshold, the rotating parts of the outdoor pan-tilt camera may not freeze and can still rotate. In this situation, heating from the heating device is unnecessary; continuous unnecessary heating increases power consumption and accelerates battery drain.
[0045] In one embodiment of this utility model, the main control circuit 10 is electrically connected to the rotating component 40, and the main control circuit 10 is used to control the rotating component 40 to rotate when the first temperature is lower than a preset threshold.
[0046] The main control circuit 10 is used to control the heating component 30 to heat the rotating component 40 when the actual rotation angle of the rotating component 40 is less than a preset angle.
[0047] In this embodiment, when the main control circuit 10 is the main controller, the main controller's transceiver interface is electrically connected to the rotating component 40. The main controller sends control signals to the rotating component 40 via the transmit interface to control the rotating component 40 to rotate at a preset angle. The rotating component 40 has a sensor for detecting the actual rotation angle, such as a Hall effect sensor. The Hall effect sensor can be used to detect the position change of the magnet inside the rotating component 40. When the magnet rotates with the rotating component 40, the Hall effect sensor generates a corresponding voltage change and outputs a corresponding voltage signal. The main controller receives the voltage signal output by the Hall effect sensor via the receive interface and determines the actual rotation angle of the rotating component 40 based on the voltage signal.
[0048] In this embodiment, when the ambient temperature is lower than a preset threshold, the main control circuit 10 outputs a control signal to control the rotating component 40 to rotate at a preset angle. Since the actual rotation angle of the rotating component 40 will be less than the preset angle when it is frozen, the main control circuit 10 controls the heating component 30 to heat the rotating component 40 when it determines that the actual rotation angle is less than the preset angle, in order to melt the ice blocking the rotating component 40 and ensure that the rotating component 40 can rotate normally. Since the actual rotation angle of the rotating component 40 is equal to the preset angle when it is not frozen, the main control circuit 10 does not control the heating component 30 to heat the rotating component 40 when it determines that the actual rotation angle is equal to the preset angle, thus avoiding unnecessary heating that would increase battery power consumption and extend the working time of the heating device of this invention.
[0049] Furthermore, when the ambient temperature is determined to be below a preset threshold, the main control circuit 10 controls the rotating component 40 to rotate at a preset angle at fixed intervals and obtains the actual rotation angle of the rotating component 40. Once it is determined that the actual rotation angle of the rotating component 40 is less than the preset angle, the heating component 30 is controlled to heat. With this configuration, when the heating device of this invention is applied to a monitoring machine, it can continuously detect the rotation angle of the rotating component 40 under low temperatures and, based on the rotation angle, promptly control the heating component 30 to melt the ice blocks frozen on the rotating component 40 when it is determined to be frozen. This allows the monitoring machine to resume normal rotation in a timely manner when frozen, ensuring that users receive a more continuous and complete monitoring image, unaffected by ambient temperature, thus enhancing the effectiveness of the security system and improving the user experience.
[0050] This utility model also proposes a monitoring machine, including a monitoring machine body and a heating device as described above.
[0051] It is worth noting that since the monitoring machine of this utility model is based on the above-mentioned heating device, the embodiments of the monitoring machine of this utility model include all the technical solutions of all the embodiments of the above-mentioned heating device, and the technical effects achieved are exactly the same, so they will not be repeated here.
[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
