Description

Technical Field

[0001] The utility model relates to the technical field of Internet of Things beacon equipment, and in particular to a vehicle-mounted Internet of Things beacon light device. Background Art

[0002] Currently, in the event of an accident or breakdown on motorways and dual carriageways, it is common to walk 50 metres along the road and place a warning triangle behind the disabled vehicle.

[0003] However, placing the warning triangle in this way and walking 50 meters back and forth along the road will bring unnecessary safety risks, and the risk will be increased on a one-way road with two-way traffic. From the analysis of previous accidents, it can be concluded that a considerable number of casualties come from collisions with pedestrians on the highway.

[0004] In addition, in adverse weather conditions such as rain, hail, strong winds, etc., the bracket of the warning triangle cannot support itself and falls down, making its signal warning function useless. In the case of reduced visibility or fog on the road, the requirement for the signal warning to be visible for 100 meters cannot be met.

[0005] Therefore, there is an urgent need to design a warning device that is safer, more efficient, and has a longer warning distance to solve the above-mentioned defects and problems of traditional warning signs. Utility Model Content

[0006] In view of this, the purpose of the utility model is to combine the latest Internet of Things technology and electronic technology to design a vehicle-mounted Internet of Things beacon light device to replace the traditional triangular warning sign. The driver does not need to walk back 50 meters to place the triangular warning sign. The vehicle-mounted Internet of Things beacon light device has a long warning distance and can be seen at a distance of more than 1,000 meters, thereby reducing the risk of the faulty vehicle being hit by the rear vehicle and the risk of being hit by the walking vehicle, and reducing the risk factor of accidents.

[0007] The utility model provides a vehicle-mounted Internet of Things beacon lamp device, comprising: a base, an annular circuit board; the annular circuit board is fixedly connected to the base, the outer circular edge of the annular circuit board is matched with a small gap between the inner wall of the base, a reflective cup is arranged in the hollow position of the annular circuit board, an LED lamp assembly is laid below the reflective cup, and the LED lamp assembly is fixedly connected to the base; a reflective cup cover is arranged above the base, and the inner surface of the reflective cup cover is a diffuse reflection curved surface;

[0008] The LED lamp assembly realizes long-distance light irradiation through reflection of the reflective cup cover, and is visible at a distance of more than 1,000 meters; the horizontal light generated by the LED lamp assembly is projected onto the diffusely reflecting reflective cup cover, making the light more uniform and full.

[0009] An electrical component is arranged on the annular circuit board, and the electrical component is electrically connected to the LED lamp component. The light emitted by the LED lamp component is directed toward the reflective cup, and the LED lamp component emits the light toward the reflective cup; the light projection direction of the reflective cup is toward the reflective cup cover, and the reflective cup projects the light toward the reflective cup cover.

[0010] Furthermore, the LED lamp assembly comprises: a plurality of SMT surface mounted light emitting diodes of the same power which are evenly arranged in a circular array with the axis of the reflective cup as the center line.

[0011] The SMT surface mounted light emitting diodes are evenly arranged in a circular array, which increases the illumination area of ​​the emitted light and makes the illumination more uniform and soft.

[0012] Preferably, the LED lamp assembly uses 6 1W yellow SMT surface mount light emitting diodes.

[0013] The light emitted by the LED lamp assembly is reflected by the reflector cup, which gathers the light in the horizontal direction, so that the light is emitted in a horizontal direction that is more convenient for the rear vehicles to see.

[0014] Furthermore, the reflective surface of the reflective cup adopts a parabolic curved surface structure, and the reflective surface is a smooth vacuum aluminum-plated layer or a smooth anodized layer.

[0015] The structural design of the reflective cup effectively reduces scattered light, glare, and light loss, achieves the best light intensity distribution, and improves reflective efficiency.

[0016] Furthermore, the electrical component includes a main control module, an LDO module (low dropout linear regulator), and a battery; the main control module and the LDO module are electrically connected to the battery via a toggle switch; the battery can be removed from and loaded into the electrical component;

[0017] Preferably, the main control module adopts the Y7080E module.

[0018] The main control module is integrated with an NB-IoT (narrowband Internet of Things) unit; the enable end of the main control module is connected to the enable pin of the LDO module, and the output end of the LDO module is electrically connected to the NB-IoT unit.

[0019] Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network, consuming only about 180kHz of bandwidth, and can be directly deployed on a GSM network, UMTS network or LTE network, reducing deployment costs and achieving smooth upgrades. Furthermore, the main control module is provided with a BAT_STAT pin and a PS_HOLD pin, which are respectively connected to the enable pin of the LDO module, and the BAT_STAT pin and the PS_HOLD pin form an OR gate logic circuit.

[0020] Furthermore, the main control module is provided with a GPIO port, and a MOS switch is connected between the GPIO port and the LED lamp assembly.

[0021] Specifically, the GPIO port outputs a periodic pulse signal to realize the on and off of the MOS switch. At the moment the MOS switch is turned on, the LED lamp assembly absorbs current from the battery, the battery is instantaneously overloaded, the battery voltage drops, and the LED lamp assembly instantly emits high brightness, causing the LED lamp assembly to flash.

[0022] MOS switches have low on-resistance and switching time, and can perform energy conversion with high efficiency, reducing energy waste. MOS switches have fast switching speeds and can complete the transition between on and off states in a short time, which helps reduce switching losses. MOS switches have small gate input capacitance and can be controlled by low-power drive circuits, thereby reducing the power consumption of the control circuit.

[0023] Furthermore, the battery is an alkaline battery with an output voltage of 9V, and the battery is connected in series with the LED lamp assembly through a resistor R.

[0024] Alkaline batteries are suitable for large discharge and long-term use. Alkaline batteries have low internal resistance and generate large current.

[0025] Furthermore, a magnet is disposed at the bottom of the base.

[0026] Magnets can firmly attach the vehicle-mounted IoT beacon light device to the roof, protecting it from strong winds and improving the weather resistance of the device.

[0027] Furthermore, the main control module is also integrated with a GPS positioning module and / or a GNSS positioning module, the GPS positioning module includes: a GPS antenna, and the GNSS positioning module includes: a GNSS antenna.

[0028] The utility model realizes the Internet of Things function through the GPS and / or GNSS positioning module, and transmits relevant accident information, location information, and equipment information to the server through the GPS antenna and / or GNSS antenna according to preset rules.

[0029] Furthermore, the main control module is integrated with a SIM card, which is used for connection to a GSM network, a W-CDMA network, and a TD-SCDMA network.

[0030] When the vehicle-mounted Internet of Things beacon light device of the utility model is not working, the toggle switch is placed in the neutral position, the enable pin level of the LDO module is in a low state, and the device does not consume battery power. When in use, the toggle switch is moved from the neutral position to the enable position, and the battery voltage pulls up the enable of the LDO module, providing the device with a 3.3V operating voltage. The device works, the LED light flashes, and related information is transmitted through the network, the PS_HOLD pin level is pulled up, and the enable pin of the LDO module is maintained at a high level.

[0031] When shutting down, move the toggle switch to the neutral position, the battery voltage is disconnected from the enable pin of the LDO, but the device will not lose power because the PS_HOLD pin pulls up the enable pin level of the LDO. After the toggle switch is moved to the neutral position, the main control module detects that the level of the BAT_STAT pin changes from low to high. The main control module determines that it needs to be shut down. After doing some pre-shutdown processing, it pulls the level of the PS_HOLD pin down to achieve power-off shutdown.

[0032] The vehicle-mounted IoT beacon light device provided by the utility model realizes the flashing and emitting of the LED component through the connection drive of the electrical component and the LED light component, and realizes the long-distance light irradiation through the structural design of the reflective cup and the reflective cup cover, and can be seen at a distance of more than 1,000 meters. When an accident or failure occurs, the driver takes the vehicle-mounted IoT beacon light device out of the car, turns it on and places it on the roof. The vehicle-mounted IoT beacon light device flashes yellow light at a fixed frequency, and the driver behind 1,000 meters away can see it and predict the occurrence of a car accident or failure in front, thereby effectively solving the defects and problems of traditional warning signs.

[0033] When a vehicle has an accident or breaks down and stops on the road and needs to warn the vehicles behind, take out the vehicle-mounted IoT beacon device, turn the toggle switch to the working position, and place it on the roof. The device will automatically turn on the flashing yellow light to warn the vehicles behind, and upload data information to the server through the NB network. When you are finished using it, remove the vehicle-mounted IoT beacon device from the roof, turn the toggle switch to the off position, and stop working and flashing.

[0034] Compared with the prior art, the beneficial effects of the utility model are:

[0035] The utility model has a simple and reasonable structure, strong integrity, long warning distance, detachable and easy-to-replace battery, no power consumption when shut down, and can replace traditional triangular warning signs. The driver does not need to walk 50 meters behind the vehicle to place the sign, thereby increasing the driver's safety. The warning distance reaches more than 1,000 meters, greatly increasing the risk avoidance reaction distance of the rear driver. The light penetration ability is strong in bad weather and can be firmly adsorbed on the roof. Even in rain, hail, strong wind, and fog, the warning reminder function for the rear vehicle driver is not affected, effectively reducing the risk factor of accidents.

[0048] The LED lamp assembly 4 includes: a plurality of SMT surface mounted light emitting diodes 41 of the same power which are evenly arranged in a circular array with the axis of the reflective cup 1 as the center line.

[0049] The SMT surface mounted light emitting diodes 41 are evenly arranged in a circular array, which increases the illumination area of ​​the emitted light and makes the illumination more uniform and soft.

[0050] In this embodiment, the LED lamp assembly 4 uses 6 1W yellow SMT surface mounted light emitting diodes. The light emitted by the LED lamp assembly 4 is reflected by the reflector cup 1, and the light is gathered in the horizontal direction, so that the light is emitted in the horizontal direction that is more convenient for the rear vehicle to see.

[0051] The reflective surface of the reflective cup 1 adopts a parabolic curved surface structure, and the reflective surface is a smooth vacuum aluminum-plated layer or a smooth anodized layer.

[0052] The structural design of the reflective cup 1 effectively reduces scattered light and glare, reduces light loss, achieves optimal light intensity distribution, and improves reflective efficiency.

[0053] The electrical components (see Figure 1 The Y7080E main control module 31, the LDO module 32 (low voltage dropout linear regulator), and the battery 33 are shown; the Y7080E main control module 31 and the LDO module 32 are electrically connected to the battery 33 through a toggle switch 34; the battery 33 can be removed from and installed in the electrical component;

[0054] In this embodiment, the main control module 31 adopts the Y7080E module.

[0055] The main control module 31 is integrated with a NB-IoT (Narrowband Internet of Things) unit; the enable end of the main control module 31 is connected to the enable pin of the LDO module 32, and the output end of the LDO module 32 is electrically connected to the NB-IoT unit.

[0056] The main control module 31 is provided with a PS_HOLD pin and a BAT_STAT pin, and the PS_HOLD pin and the BAT_STAT pin are respectively connected to the enable pin of the LDO module 32; the BAT_STAT pin and the PS_HOLD pin form an OR gate logic circuit.

[0057] In this embodiment, the BAT_STAT pin is grounded by default through a 100K resistor, the BAT_STAT pin is at a low level, and the enable pin level of the LDO module 32 is in a pulled-down state. When the toggle switch 34 is toggled from the neutral position to the enable position, the level of the BAT_STAT pin changes from low to high, and the enable of the LDO module 32 is pulled high. The LDO module 32 pulls up the level of the PS_HOLD pin, and the BAT_STAT pin and the PS_HOLD pin form an OR gate through two diodes (if the level of one of the two is high, the output is high), maintaining the enable pin of the LDO module 32 at a high level.

[0058] When the toggle switch 34 is turned to the neutral position, the BAT_STAT pin is pulled low and connected. Because the PS_HOLD pin pulls up the enable pin level of the LDO module 32, the device will not lose power. After the toggle switch 34 is turned to the neutral position, the main control module 31 detects that the level of the BAT_STAT pin changes from high to low, and the main control module 31 pulls down the level of the PS_HOLD pin to achieve power-off shutdown of the device.

[0060] The Internet of Things function is realized through the GNSS positioning module. According to the preset rules, relevant accident information, location information, and equipment information are transmitted to the server through the GNSS antenna.

[0061] The main control module 31 is provided with a GPIO port, and a MOS switch is connected between the GPIO port and the LED lamp assembly 4. The GPIO port outputs a periodic pulse signal to realize the on and off of the MOS switch. When the MOS switch is turned on, the LED lamp assembly 4 absorbs current from the battery 33, the battery 33 is instantly overloaded, the voltage of the battery 33 drops, and the LED lamp assembly 4 instantly emits high brightness, causing the LED lamp assembly 4 to flash.

[0062] The battery 33 is an alkaline battery with an output voltage of 9V. The battery 33 is connected in series with the LED lamp assembly 4 via a resistor R.

[0064] When encountering strong winds, the vehicle-mounted IoT beacon light device can be firmly attached to the roof through magnets, so it will not be affected by strong winds, improving the weather resistance of the device.

[0065] The main control module 31 is integrated with a SIM card 35 .

[0066] The SIM card 35 can be used for connection to a GSM network, a W-CDMA network and a TD-SCDMA network.

When in use, the toggle switch 34 is moved from the neutral position to the enable position, and the voltage of the battery 33 will pull up the enable of the LDO module 32, providing the device with a 3.3V operating voltage. The device works, the LED light component 4 flashes, and related information is transmitted through the network, the PS_HOLD pin level is pulled up, and the enable pin of the LDO module 32 is maintained at a high level.

[0068] When shutting down, turn the toggle switch 34 to the neutral position, the voltage of the battery 33 is disconnected from the enable pin of the LDO module 32, but the device will not lose power because the PS_HOLD pin pulls up the enable pin level of the LDO. After the toggle switch 34 is turned to the neutral position, the main control module 31 detects that the level of the BAT_STAT pin changes from low to high. The main control module 31 determines that it needs to be shut down. After doing some pre-shutdown processing, the level of the PS_HOLD pin is pulled down to achieve power-off shutdown.
