Description

Smart lamps and site management system

The present invention relates to a smart lamp and a construction site management system, in particular to a smart lamp and a construction site management system capable of detecting objects or dumping.

With the improvement of labor safety and hygiene awareness, the safety of construction sites has been paid more and more attention in recent years. In particular, there are many emergencies on the construction site. In order to improve the safety of the construction site, it is often necessary to place traffic cones around the construction site to divert motor vehicles or pedestrians to avoid accidents caused by motor vehicles or pedestrians entering the construction site by mistake. Traditionally, because the traffic cones are not particularly eye-catching, the effect of avoiding vehicles or pedestrians from entering the construction site is very limited. For example, careless drivers often run over or knock down traffic cones. If they are not found in time, they are likely to injure the people under construction. In addition, pedestrians often ignore the guidance of traffic cones because they are greedy for convenience, and crossing the construction site directly exposes pedestrians to danger.

In other words, traditional traffic cones are only used to assist in reminding cars, motorcycles or pedestrians. Most of the time, it is necessary to assign personnel to control the site conditions on the construction site. However, when the area of the construction site is large or the control is loose, it is still not possible to detect cars or pedestrians entering the construction site by mistake. Therefore, the industry needs a new intelligent lighting and construction site management system that can automatically detect whether there are cars, motorcycles or pedestrians entering the construction site by mistake, and reduce the manpower requirements of the controller. In addition, when a car or a pedestrian accidentally enters the construction site, the intelligent lighting and construction site management system should also be able to notify relevant personnel in time to avoid accidents.

The present invention provides a smart lamp, which can automatically detect surrounding objects, and can issue a notification when it is dumped, thereby reducing the manpower requirement of the controller.

The present invention provides a smart lamp including a body, a light-emitting unit, an object detection unit, and a wireless communication unit. The light emitting unit is arranged in the body to emit light. The object detection unit is arranged in the main body to detect whether there is an object in the detection area and generate an object detection signal accordingly. The wireless communication unit is electrically connected to the object detection unit for selectively transmitting object detection signals.

In some embodiments, the object detection unit can send a light signal or a sound signal in the detection area, and can be used to receive the light signal or sound signal of another object detection unit. When the object detection unit does not receive another A light signal or a sound signal from an object detection unit, and the object detection unit generates an object detection signal. In addition, the object detection unit can also be used to shoot an image frame in the detection area. When the object detection unit determines that there is an object in the image frame, the object detection unit generates an object detection signal. In addition, the main body may have a rod body for inserting into the hole of the traffic cone. Alternatively, the body may have a magnet unit, and the magnet unit is used to adsorb the casing of the mechanical device. Alternatively, the body may be a traffic cone, and the light emitting unit is exposed on the outer surface of the traffic cone.

In some embodiments, the smart lamp may further include a tipping detection unit, disposed in the body, to determine whether the body is tilted beyond a predetermined angle to generate a tipping detection signal, and the wireless communication unit is more electrically connected to the tipping The detection unit is used for selectively transmitting the object detection signal and the dumping detection signal. When the wireless communication unit receives at least one of the object detection signal and the dump detection signal, the wireless communication unit may wirelessly transmit at least one of the received object detection signal and the dump detection signal to the management platform.

The present invention provides a smart lamp, which can automatically detect surrounding objects, and can issue a notification when it is dumped, thereby reducing the manpower requirement of the controller.

The features, objectives and functions of the present invention will be further disclosed below. However, the following are only examples of the present invention, and should not be used to limit the scope of the present invention, that is, all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention will still be the essence of the present invention. Without departing from the spirit and scope of the present invention, it should be regarded as a further embodiment of the present invention.

Please refer to FIGS. 1 and 2 together. FIG. 1 is a functional block diagram of a construction site management system according to an embodiment of the present invention, and FIG. 2 is a functional block diagram of an intelligent lamp according to an embodiment of the present invention. As shown in the figure, this embodiment demonstrates that the construction site management system 1 can have a management platform 10 and a plurality of smart lamps 12a-12c, and the management platform 10 can be connected to the smart lamps 12a-12c through wireless transmission. In practice, the management platform 10 can remotely receive various signals from the smart lamps 12a-12c, and can transmit various control commands to the smart lamps 12a-12c according to the built-in functions of the smart lamps 12a-12c. This embodiment does not limit the type of the management platform 10 here. For example, the management platform 10 may be a server, a computer, a notebook computer, or other electronic devices with certain computing capabilities.

The smart lamps 12a-12c can be the same as each other. Taking one of the smart lamps 12a as an example, as shown in FIG. 2, the smart lamp 12a includes a main body 120, a light-emitting unit 122, an object detection unit 124, a tipping detection unit 126, and Wireless communication unit 128. Here, the present embodiment does not limit the shape of the main body 120. For example, the main body 120 may be spherical, cylindrical, cubic, or cone-shaped like a traffic cone. Those with ordinary knowledge in the technical field can freely choose. The light-emitting unit 122 is disposed in the main body 120 to emit light. For example, the light-emitting unit 122 may be a common light-emitting device such as a bulb, a light-emitting diode, or an organic light-emitting diode, and the body 120 may be a transparent, semi-transparent or partially transparent cover. The main body 120 may have an environmental protection function. For example, the light-emitting unit 122 may be protected by the main body 120 so as to be waterproof, dustproof, anti-squeeze, or drop-proof.

The smart lamp 12a of this embodiment can be used in different situations, and the main body 120 can be designed with various structures to be combined with different devices. For example, if the smart lamp 12a can be combined with an existing traffic cone, a pole (not shown) can be designed on the main body 120, and the pole can extend from the bottom of the main body 120, and the thickness of the pole It can exactly match the diameter of the hole at the top of the traffic cone. Thereby, when the rod on the main body 120 is inserted into the hole on the top of the traffic cone, the smart lamp 12a can be fixed on the top of the traffic cone. Or, if the smart lamp 12a can be combined with various existing mechanical equipment, such as a strange hand or a steel bending machine, the bottom of the main body 120 can be designed with a magnet unit (not shown). When the magnet unit on the main body 120 adsorbs the metal surface (such as the housing) of the mechanical device, as long as the magnetic force of the magnet unit is strong enough, the smart lamp 12a can be firmly combined with the mechanical device. Or, the main body 120 itself may be in the shape of a traffic cone, as long as the light emitted by the light-emitting unit 122 can penetrate the traffic cone. In other words, the appearance of the smart lamp 12a can have various changes. Even if it is designed as a traffic cone that can emit light, it should fall within the scope of this embodiment.

The object detection unit 124 is disposed in the main body 120 to detect whether there is an object in the detection area A and generate an object detection signal accordingly. In practice, the object detection unit 124 may be an optical or acoustic sensor, such as an infrared sensor or an ultrasonic sensor. Taking the object detection unit 124 as an infrared sensor as an example, the object detection unit 124 can send and receive infrared signals (light signals) in the detection area A, and determine whether there is an object in the detection area according to the change of the infrared signal In A. For example, the object detection unit 124 of the smart lamp 12a can receive infrared signals from the smart lamp 12b. When the object detection unit 124 of the smart lamp 12a does not receive the infrared signal, the object detection unit 124 can determine An object passes between the smart lamp 12a and the smart lamp 12b, and the infrared signal is blocked. At this time, the object detection unit 124 can generate an object detection signal to indicate that the detected object enters the detection area A.

Similarly, taking the object detecting unit 124 as an ultrasonic sensor as an example, the object detecting unit 124 can send and receive ultrasonic signals (sound signals) in the detection area A, and determine whether the ultrasonic signal changes according to the ultrasonic signal. There is an object in the detection area A. For example, the object detection unit 124 of the smart lamp 12a may pre-record the ultrasonic signals that it will receive at the current location, such as the ultrasonic signal from the smart lamp 12b or the ultrasonic signal reflected by the environmental object. When the ultrasonic signal at a certain time point is different from the preset ultrasonic signal, the object detection unit 124 can determine that there is an object in the detection area A, which changes the intensity or field pattern of the ultrasonic signal. At this time, the object detection unit 124 can generate an object detection signal to indicate that the detected object enters the detection area A.

In one example, the object detection unit 124 can also be used to capture an image frame in the detection area A. When the object detection unit 124 determines that there is an object in the image frame, the object detection unit 124 generates an object detection signal. In practice, the object detection unit 124 may be an image capturing device for shooting the surrounding environment, and the object detection unit 124 may analyze the captured image frame to determine whether there is a preset pattern. Taking a practical example, the object detection unit 124 may first record some data patterns, such as vehicle patterns and personnel patterns, when the object detection unit 124 can analyze the images of the aforementioned vehicle patterns and personnel patterns. With the pattern, it can be determined that there is an object to be compared in the image frame, thereby generating an object detection signal. Of course, the object detection unit 124 also has the opportunity to perform more detailed image analysis on the pattern of the vehicle and the pattern of the person. For example, it can further check whether the license plate of the vehicle is a registered license plate, or whether the person wears a designated object (such as a safety helmet or Reflective vests). For example, when the license plate of the vehicle is not a registered license plate, or the person does not wear a designated object, the object detection unit 124 may also generate an object detection signal.

The tipping detection unit 126 is disposed in the main body 120 to determine whether the main body 120 is tilted beyond a predetermined angle, and thereby generate a tipping detection signal. For example, the dump detection unit 126 may include a gyroscope or a mercury switch, and the preset angle may be 30 degrees, 45 degrees, 60 degrees, or 90 degrees, which is not limited in this embodiment. In one example, since the smart lamp 12a is placed around the construction site, the smart lamp 12a is likely to be knocked down by a machine or intruded person or car, or fall over due to drastic changes in the environment such as a collapse. The unit 126 can then generate a dump detection signal. Since the above-mentioned tipping of the smart lamp 12a usually increases the risk of workers on the construction site, it is different from the object detection unit 124 of this embodiment detecting whether an object enters the detection area A, and the tipping detection unit 126 is used as the second The heavy judgment mechanism can be used to judge whether a more urgent danger occurs on the construction site.

It is worth mentioning that although FIG. 2 shows the object detection unit 124 and the dump detection unit 126, the smart lamp 12a does not have to have the object detection unit 124 and the dump detection unit 126 at the same time. In other words, the smart lamp 12a only has the object detection unit 124 or only the dump detection unit 126, which is also operable. Those with ordinary knowledge in the relevant technical field should understand that if the smart lamp 12a has only one of the object detection unit 124 and the dump detection unit 126, the functions of the smart lamp 12a will be reduced and only object intrusion detection can be performed. Test or determine whether the smart lamp 12a is overturned, but the lack of one function will not affect the normal operation of the other function.

Continuing back to FIGS. 1 and 2, the wireless communication unit 128 is electrically connected to the object detection unit 124 and the dump detection unit 126, and can selectively transmit the object detection signal and the dump detection signal to the management platform 10. In practice, the wireless communication unit 128 may have an independent network connection function. For example, it may be connected to the management platform 10 via 4G, 5G, WiFi, LoRa, Zigbee or other signal transmission technologies, which is not limited in this embodiment. In one example, the wireless communication unit 128 does not limit the types of signals that can be transmitted. As long as the wireless communication unit 128 is connected to an appropriate detector, the wireless communication unit 128 can also transmit the brightness, humidity, image and sound signals to the management platform. 10.

Taking the actual operation example, assuming that the smart lamps 12a-12c are installed on the traffic cone, the detection area A can be set as a controlled area. When the object detection unit 124 of the smart lamp 12a detects that the object enters the detection area A, the wireless communication unit 128 of the smart lamp 12a transmits the object detection signal to the management platform 10. At this time, since the object detection signal carries a management number, such as an SSID, the management platform 10 can immediately find the management number to know the physical location of the smart lamp 12a. In other words, when the management platform 10 can immediately know that the object enters the controlled area (detection area A), and can initiate emergency response measures corresponding to the physical location. For example, after the management platform 10 learns that the object has entered the controlled area, it can immediately notify the managers at the site, the surrounding site, or the neighboring site, and the manager will check whether there is any abnormality. In one example, the administrator’s mobile device 14 (such as a mobile phone, tablet) may be pre-installed with an application program that can be connected to the management platform 10, and the management platform 10 may transmit instructions to the application program to cause the application program to issue Alarm or pop up the information window to remind the manager of abnormal events.

In one example, the management platform 10 can determine the degree of urgency by itself. For example, when a single smart lamp 12a detects that an object enters the detection area A, it may be a low-urgency event. Then, when multiple smart lamps 12a-12c simultaneously detect that an object enters the detection area A, the urgency may be higher than the aforementioned event. The dumping of a single smart lamp 12a may be more urgent than the aforementioned events. If multiple smart lamps 12a~12c dump continuously, it may be the most urgent event. This embodiment only demonstrates a rule that the management platform 10 can determine the degree of urgency on its own. Those with ordinary knowledge in the relevant technical field can set it according to the conditions of the construction site, and this embodiment is not limited here.

Of course, the present embodiment does not limit the mobile device 14 to be held by the manager, and the mobile device 14 may also be equipped on the personnel of the construction site. For example, all construction personnel can be equipped with mobile devices 14. If the management platform 10 learns that an object has invaded the construction site, such as a detected object around a smart lamp 12a in a physical location, it can only notify the management者的mobile device14. If the smart lamps 12a~12c at a certain physical location are continuously dumped, the management platform 10 can link the mobile devices 14 of all construction personnel within a certain range (or the entire construction site) around the physical location and synchronize them. An alarm is issued to warn of possible danger.

In addition, after the management platform 10 receives the object detection signal or/and the dumping detection signal, it can also immediately activate one or more cameras 16 on the construction site, around the construction site, or adjacent to the construction site, and the cameras 16 can record the situation of the construction site in real time. To facilitate tracking of intrusive objects or subsequent clarification of responsibility. In one example, since the smart lamps 12a~12c can be set at the boundary of the construction site, the shooting frame of the camera 16 can include the smart lamps 12a~12c, in order to quickly determine which object enters the detection area A (or enters Construction site). In addition, the camera 16 can be controlled by the management platform 10 with the networking function, and the management platform 10 can transmit instructions to the camera 16, so that the camera 16 can start the photography function in time or be controlled to a specific direction for effective recording. This is an abnormal event.

In another example, the main body 120 of the smart lamp 12a may have an alarm device such as a buzzer (not shown). When the object detection unit 124 determines that there is an object intrusion, or the tipping detection unit 126 determines that the smart lamp 12a is tipped by an external force, in addition to the wireless communication unit 128 notifying the management platform 10, the buzzer can also sound simultaneously. Warn nearby people or deter intruders. In addition, the main body 120 of the smart lamp 12a may also have power equipment such as a solar charging panel (not shown) and a battery (not shown) to facilitate long-time outdoor work.

On the other hand, the light-emitting unit 122 may not only be a simple light bulb, but may also be composed of light-emitting diodes of multiple colors. In practice, the management platform 10 may also use the wireless communication unit 128 to control whether the light-emitting unit 122 is activated, the color temperature of the light emitted, or the flash frequency of the light emitted. For example, the object detection unit 124 determines that there is an object intrusion, or the tipping detection unit 126 determines that the smart lamp 12a is tipped by an external force. After the wireless communication unit 128 notifies the management platform 10, the management platform 10 may return a control signal To the wireless communication unit 128, the light emitting unit 122 can selectively emit the first color light or the second color light according to the control signal, so the light emitting unit 122 may also be used as a temporary traffic control sign. In terms of actual operation, if a smart lamp (for example, the smart lamp 12a is inserted into a traffic cone) or a group of smart lamps is temporarily installed at the first end entrance of a narrow road, the management platform 10 can fully monitor Whether there are people passing by at the first entrance. At this time, as long as another smart lamp or another group of smart lamps is installed at the entrance of the second end of the narrow road, the management platform 10 will receive an object detection signal when there is a traffic passing by the entrance of the first end. And can control the light emitting unit 122 of the smart lamp at the second end entrance to emit red (usually green or flashing yellow), so that the construction site management system 1 of this embodiment can be used to quickly set the function of temporary traffic control signs .

In summary, the smart lamps and construction site management system provided by the present invention can automatically detect surrounding objects by the smart lamps, and can notify the management platform when it is dumped. The management platform can then use various means to notify the surrounding personnel, or integrate and manage the cameras around the construction site, so as to manage the construction site in real time and reduce accidents on the construction site. In addition, smart lamps are very easy to set up, and it is easy to integrate other monitoring equipment through the management platform, which can support the temporary control needs of many construction sites.
