Description

Technical Field

[0001] The present application relates to the technical field of emergency response, and in particular to a lighting device integrated with emergency response equipment for unmanned aerial vehicles. Background Art

[0002] In rescue, firefighting and some emergency scenarios, using drones equipped with some emergency response equipment for rescue and emergency response is a very good choice. At present, emergency light sources are usually installed directly under the drone fuselage or other mounting points. This method can quickly illuminate the required area with the help of the drone's high-altitude hovering and mobility capabilities. Some emergency light sources have their own batteries and can work relatively independently, but due to the limited battery capacity, batteries need to be replaced frequently to maintain lighting during long-term emergency lighting tasks. If the emergency light source does not come with a battery, on-site staff are required to disassemble and assemble the drone and connect the emergency light source to the drone power supply to achieve emergency lighting.

[0003] For emergency light sources with built-in batteries, the limited battery capacity makes it difficult to provide continuous lighting for a long time. Frequent battery replacement not only increases the complexity and workload of the operation, but may also delay the precious time of emergency rescue due to the replacement process, affecting the rescue efficiency. For emergency light sources without batteries, the requirements for disassembly and assembly of drones on site are too complicated, which requires high technical level and operational proficiency of the staff. In addition, in emergency scenarios, the disassembly and assembly process is time-consuming and laborious, making it difficult to provide lighting support in a timely and effective manner, which brings many inconveniences to emergency rescue work.

[0051] Below is a combination of the embodiments and Figure 1-Figure 6The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0052] The present invention discloses a lighting device integrated with emergency response equipment for a drone, specifically comprising:

[0053] Airborne light source assembly for lighting.

[0054] The onboard power management component is connected to the onboard light source component and is used to provide power to the onboard light source component.

[0055] The onboard tethering component is connected to the onboard power management component and is used to obtain power from the tethering cable and transmit it to the onboard power management component.

[0056] The tension detection component is used to detect the tension of the mooring cable.

[0057] The communication component is connected to the tension detection component signal, used to receive the tension of the tethered cable and control and adjust the length of the cable, and is connected to the airborne light source component to control the lighting brightness.

[0058] In actual use, the airborne light source assembly is used for lighting, the airborne power management assembly can convert the electric energy transmitted by the airborne tethered assembly into the power required by the airborne light source assembly, the tension detection assembly can detect the tension of the tethered cable exerted on the airborne tethered assembly, and generate a control signal according to the tension value, which is transmitted to the tethered cable controller through the communication assembly to adjust the length of the cable. These five parts all use lightweight and small devices and have integrated interfaces for easy installation.

[0059] The airborne light source assembly includes a lighting device, a brightness controller and a current detection assembly.

[0060] The brightness controller is connected to the lighting device, and according to the preset brightness level, the corresponding current is found according to the preset current-brightness level comparison table and recorded as the standard current.

[0061] The brightness controller is connected to a current detection component, and the current detection component is used to detect the current in the circuit to obtain the real-time current.

[0062] The brightness controller controls and adjusts the current until the real-time current is consistent with the standard current.

[0063] Lighting devices are used for lighting.

[0064] In actual use, the brightness of the lighting device is controlled by a brightness controller. The current detection component detects the brightness of the lighting device and transmits the brightness value to the brightness controller. At the same time, the brightness controller can also accept the brightness value sent by the communication component. The brightness of the lighting device is controlled by these two methods. Among them, the priority of the communication component is higher than that of the current detection component. That is to say, if the communication component does not receive the brightness control value, the brightness controller only controls the lighting device to emit light according to the pre-set brightness value. If the communication component receives the brightness control value, the brightness controller controls the lighting device to emit light according to the brightness value transmitted by the communication component, and the current detection component performs real-time current detection to ensure that the brightness of the lighting device meets the required brightness value.

[0065] The onboard power management components include power conversion components, power detection components, safety switches and alarms.

[0066] The power conversion component is connected to the onboard tethering component and is used to receive power from the tethering cable and convert it into power for the mechanical light source component.

[0067] The power detection component is connected to the onboard tethering component and is used to detect whether the power supply of the tethering cable is within a preset normal range.

[0068] If it is not within the preset normal range, the safety switch is controlled to close, the power provided by the mooring cable is cut off, and the alarm is controlled to sound an alarm.

[0069] If it is within a preset normal range, the power of the tethered cable is converted into the power of the mechanical light source assembly.

[0070] In actual use, the voltage detector can detect the voltage value received by the tethered cable socket and determine whether the voltage value is within the specified voltage range (i.e., the voltage range supported by the power converter). If so, the safety switch is controlled to close to connect the tethered cable socket and the power converter. If not, the safety switch is controlled to open to disconnect the tethered cable socket and the power converter. Furthermore, an alarm is connected to the voltage detector. When the voltage detector determines that the voltage value is not within the specified voltage range, the alarm can be controlled to sound an alarm.

[0071] The power conversion group includes a power converter, a first connector and a second connector.

[0072] The power converter is used to convert the power of the tethered cable into the power of the mechanical light source assembly.

[0073] The first connector is connected to the power converter and is used to receive the converted power and distribute it to the lighting device.

[0074] The second connector is connected to the original tethered cable socket on the tethered drone, receives the converted power and distributes it to the drone.

[0075] In actual use, the first connector is used to connect to the tethered cable interface of the lighting device to provide the power allocated by the power converter to the lighting device for lighting the lighting device. The second connector is used to connect to the original tethered cable socket on the tethered drone to provide the power allocated by the power converter to the tethered drone for use, thereby ensuring the normal operation of the tethered drone.

[0076] Reference Figure 6 A safety switch is provided between the tethered cable socket and the power converter, and a voltage detector connected to the safety switch is also provided. Based on this, the voltage detector can detect the voltage value received by the tethered cable socket and determine whether the voltage value is within a specified voltage range (i.e., the voltage range supported and processed by the power converter). If so, the safety switch is controlled to close to connect the tethered cable socket and the power converter; if not, the safety switch is controlled to open to disconnect the tethered cable socket and the power converter.

[0077] Furthermore, an alarm may be connected to the voltage detector. When the voltage detector determines that the voltage value is not within the specified voltage range, the alarm may be controlled to sound an alarm.

[0078] The power converter includes a first DC chopper and a second DC chopper.

[0079] The first DC chopper is connected to the mooring cable to obtain electric energy provided by the mooring cable.

[0080] The second DC chopper is connected to the first DC chopper, and is used to perform voltage conversion on the first voltage converted by the first DC chopper to obtain a second voltage suitable for the tethered drone, and provide electrical energy to the second connector according to the second voltage.

[0081] In actual use, the first DC chopper is connected to the tethered cable socket provided by the device to obtain the electrical energy provided by the tethered cable from the socket. The first DC chopper performs voltage conversion on the obtained electrical energy to obtain a first voltage suitable for the lighting device, and provides electrical energy to the first connector according to the first voltage. In other words, electrical energy that meets its voltage requirements (i.e., the first voltage) is provided to the lighting device. The second DC chopper continues to perform voltage conversion on the first voltage converted by the first DC chopper to obtain a second voltage suitable for the tethered drone, and provides electrical energy to the second connector according to the second voltage. In other words, electrical energy that meets its voltage requirements (i.e., the second voltage) is provided to the tethered drone.

[0082] Reference Figure 4, where Vpower is the power received by the tethered cable socket. In order to reduce the power supply voltage proportionally to a suitable value for comparison by the comparator, two resistors R1 and R2 are used to form a voltage divider circuit. The power supply Vpower is divided in series by R1 and R2, and the divided voltage value V_sampling is obtained at both ends of R2. According to the series voltage division formula V_sampling = V_in*R2 / (R1+R2). Here, by reasonably selecting the resistance values ​​of R1 and R2, the actual power supply voltage can be reduced to a suitable range that the comparator can handle according to the demand ratio, such as converting a higher power supply voltage into a range of several volts for subsequent circuits.

[0083] Use a voltage comparator (such as LM393, etc.), the comparator has two input terminals, here the voltage division V_sampling is connected to the inverting input terminal of the comparator (indicated by -). At the same time, the upper and lower limit reference voltages are set by cooperating with the reference power supply V_ref (a stable reference voltage source can be used here, such as a 5V reference voltage chip, as the reference power supply), and are connected to the non-inverting input terminal of the comparator (indicated by +). R3 and R4 are connected in series across the reference power supply V_ref, and different upper and lower limit voltage values ​​can be obtained by adjusting their resistance ratio (for example, adjusting the resistance of R3 can set the upper limit reference voltage V_high_ref, and adjusting the resistance of R4 can set the lower limit reference voltage V_low_ref).

[0084] When V_sampling is greater than V_high_ref or less than V_low_ref, the level of the comparator output will change (for example, from high level to low level or vice versa, depending on the type and configuration of the comparator) to reflect that the power supply voltage exceeds the set range.

[0085] Relay drive and safety switch control part: The output end of the comparator is connected to the base of a transistor Q1 (for example, an NPN transistor, such as the commonly used 9013, etc.), and an electromagnetic relay K1 is driven by the transistor Q1. The collector of the transistor is connected to one end of the coil of the relay K1, and the other end of the coil is connected to the power supply Vpower. At the same time, a diode D1 is connected in parallel at both ends of the relay coil (generally a freewheeling diode, such as 1N4148, is used to provide a release circuit for the self-inductance electromotive force generated by the relay coil when the power is off, protecting the transistor and other circuit components). When the comparator outputs a high level (indicating that the voltage is within the normal range), the transistor Q1 is turned on, the relay K1 coil is energized, and its normally open contact is closed. When the comparator outputs a low level (indicating that the voltage is out of range), the transistor Q1 is turned off, the relay K1 coil is de-energized, and its normally open contact is disconnected. The safety switch can be connected in series with the normally open contact of the relay, so that when the relay contact is disconnected, the safety switch is also disconnected.

[0086] The output end of the comparator can also be connected to another transistor Q2 (for example, a PNP transistor), which is opposite to the on and off of Q1. An electromagnetic relay K2 is driven by the transistor Q2. Relay K2 can control the on and off of the alarm, and the on and off of the alarm is opposite to the on and off of the safety switch.

[0087] Reference Figure 5 VPOWER is the power provided by the tethered cable, where J1 is the tethered cable socket. The power supply VPOWER converts the power provided by the tethered cable into the DVDD5v power required by the lighting device through the MP2315 chip (a DC chopper chip), and outputs the DVDD5v power to the lighting device through the first connector. Based on the DVDD5v power, the ME6211C33 chip (another DC chopper chip) continues to convert the DVDD5v power into DVDD3.3v power, and outputs the DVDD3.3v power to the tethered drone through the second connector.

[0088] Among them, capacitors C2 and C3 are used for filtering to ensure the voltage stability on the in and vcc pins of the MP2315 chip. Resistor R1 and capacitor C1 are used to provide the required voltage for the BST pin (Chinese name is the boot pin) of the MP2315 chip, and inductor L1 is used for voltage stabilization to ensure the stable output of DVDD5v power. Resistor R2 and capacitor C5 are used to provide the required voltage for the AAM pin (Chinese name is the advanced asynchronous modulation pin) of the MP2315 chip.

[0089] The onboard tethering assembly includes a cable fixing buckle and a tethering cable interface.

[0090] The cable fixing buckle is used to fix the tethered cable.

[0091] The tethered cable interface is used to receive power transmitted by the tethered cable.

[0092] The tension detection component includes a tension sensor and a tension controller.

[0093] The tension sensor is used to detect the tension of the tethered cable on the drone.

[0094] The tension controller is connected to the tension sensor signal and is used to receive the tension of the tethered cable on the drone and determine whether the tension of the tethered cable on the drone exceeds a preset tension value.

[0095] If the tension exceeds a preset value, a control signal is generated and transmitted to the communication component.

[0096] The communication component includes a sending module, a first receiving module, a second receiving module and a tethered cable controller.

[0097] The sending module and the first receiving module are both installed on the drone, and the second receiving module is installed on the tethered cable controller.

[0098] The sending module is connected to the tension controller signal, and is used for receiving the control signal and sending it to the second receiving module.

[0099] The second receiving module is signal-connected to the sending module, and is used for receiving the control signal and transmitting the control signal to the tethered cable controller.

[0100] The tethered cable controller is connected to the receiving module signal, and is used to receive the control signal and control the retraction and extension action of the cable according to the control signal.

[0101] The first receiving module is connected to the airborne light source assembly signal and is used to control the lighting brightness.

[0102] In actual use, the tension detection module transmits the detected tension value to the controller, and the controller generates a control signal according to the tension value and transmits it to the sending module. The sending module sends the control signal to the second receiving module, and the cable controller performs the cable retraction and extension operation according to the control signal of the second receiving module. The cable controller is a cable controller of an ordinary tethered drone that already exists on the market, and the second receiving module in the communication component is installed on the cable controller. Since the tethered cable will be affected by wind or other human accidental contact, the tension of the tethered cable on the drone will increase, which will change the position of the drone and cause the lighting range to deviate. After using this solution, the retraction and extension of the tethered cable can be adjusted in real time according to the tension, so as to ensure that the position of the drone remains unchanged and the lighting range is stable. A tethered drone is a drone connected to a ground power supply and data transmission system through a tethered cable. This tethered cable usually contains a power line and a signal line, which, on the one hand, continuously provides power to the drone, and on the other hand, is used to transmit control signals and data. Compared with traditional drones that rely on their own batteries for power supply, tethered drones are free from the limitations of battery power and flight time.

[0103] The first receiving module is connected to the brightness controller signal. The first receiving module collects the brightness signal set by the user and transmits the brightness signal to the brightness controller. The brightness controller controls the brightness of the lighting device according to the brightness signal.

[0104] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
