Description

Technical Field

[0001] The utility model belongs to the technical field of lighting system network configuration tooling, and particularly relates to an optical information receiving and positioning device. Background Art

[0002] The intelligent lighting market is growing rapidly, and the integration with fields such as the Internet of Things and artificial intelligence has promoted product innovation. The application scenarios have expanded from commercial to home and urban lighting, and policy support and product diversification have improved the user experience. With the rapid growth of labor costs, how to improve the usability and ease of installation of the system has become a bottleneck restricting the popularization and use of intelligent systems. Simplifying the installation and commissioning process of equipment so that traditional lighting construction workers can use it is a key link in accelerating the implementation of intelligent lighting systems.

[0003] There are generally several ways for existing devices to access the network: 1. The device is pasted with a label, and the address, password and other information of the device are obtained by scanning the code with a mobile phone, and then the device is added to the gateway. This method is reliable, but it requires training on-site installation and commissioning personnel to be familiar with the device addition and installation process, and the shell needs to have enough space to paste the label. In addition, if the label is damaged, it cannot be installed; 2. The device is built-in with NFC, and the mobile phone obtains the address, password and other information of the device through NFC communication. This scheme is convenient for debugging, but it requires enough space in the device for installation, and the NFC antenna needs to be separated from the internal circuit of the device, increasing the cost; 3. The device has an active reporting function, and reports the address, password and other information of the device to the gateway, and then determines the correspondence between the address and the device by turning the light on and off. If there are many devices, the device indication is very complex. 4. Buttons are set on the device, and authentication and network access are carried out through the buttons. However, general lighting devices are installed on the roof, so button-based network access is not only complex in operation but also difficult.

[0004] In summary, on-site lighting devices are installed on the roof and are not easily accessible. The above several network access schemes all have certain difficulties in implementation. If a non-contact and short-distance device is used to obtain the address, password and location and other information of the device, the installation and commissioning process of the device will be greatly simplified.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0024] As Figure 1 shown, the embodiment of the present invention provides an optical information receiving and positioning device, including: a power supply, a processor, a laser emission module, a photosensitive sensor, a photosensitive receiving and amplifying circuit, a communication circuit and a positioning module. The photosensitive sensor is connected to the input end of the processor through the photosensitive receiving and amplifying circuit. The control end of the laser emission module is connected to the output end of the processor through a switch circuit. The processor is connected to a host computer through the communication circuit. The output end of the positioning module is connected to the input end of the processor. Among them, the photosensitive sensor is used to receive the optical signal emitted by the lighting lamp. The laser emission module is used to emit laser to facilitate alignment of the photosensitive sensor with the lighting lamp. The positioning module is used to position the lighting lamp.

[0025] Specifically, in this embodiment, the communication circuit is a Bluetooth transceiver circuit. After the processor receives the optical signal carrying communication address information sent by the lighting lamp, it sends the optical signal to the host computer. At the same time, the processor also sends the position information of the lighting lamp measured by the positioning module to the host computer. Then, the host computer can obtain the position information and address information of the lighting lamp simultaneously, which is not only convenient for the lighting lamp to access the network but also convenient for providing the necessary lamp coordinate information for the graphical management device. In addition, the communication circuit can also be a USB communication circuit. After the processor obtains the lamp device information and position information, it transmits this information to a computer or a mobile phone APP through a USB interface or a Bluetooth interface. In addition, the device is powered through a USB interface, and the power supply can be provided by a mobile phone or a power bank, etc.

[0026] Specifically, the lighting lamp is an intelligent lamp. When it accesses the network, it sends an instruction to the lamp through a gateway, enabling the lamp to send lamp device information through the flashing of the light. The device information includes the network address ID and password of the lamp, etc. The lamp includes an LED optical communication control circuit. The optical communication control circuit can quickly turn on and off the power supply of the LED and send the device information of the lamp outward in the form of light flashing. This flashing is invisible to the human eye, with a frequency above 1KHz but not higher than 10KHz to adapt to the response time of the photosensitive sensor. The photosensitive sensor can detect changes in light intensity. The photosensitive component is in a high-resistance state in a dark environment, and a weak current (uA level) is generated by the photosensitive component in a bright environment. Then, the device information sent by the lamp through flashing can be received through the photosensitive device.

[0027] Specifically, as Figure 2 shown, an optical information receiving and positioning device of this embodiment further includes a housing 1. An emission cylinder 2 for shielding stray light is arranged inside the housing. The photosensitive sensor 3 and the laser emission module 4 are arranged at the bottom of the emission cylinder 2, and the positioning module is arranged outside the emission cylinder 2. By providing the emission cylinder 2, the light receiving angle of the photosensitive component can be limited to be very small. For example, less than 15 degrees, so that the mutual influence of the flashing information lights sent by adjacent lamps simultaneously can be avoided. It should be noted that the emission cylinder 2 is in a cylindrical shape. Figure 2 For the convenience of understanding, only a part of the emission cylinder 2 is drawn.

[0028] Specifically, as Figure 2 and Figure 5As shown in the figure, in this embodiment, the positioning module includes two laser ranging modules 7 placed perpendicular to each other. The ranging directions of the two laser ranging modules 7 are perpendicular to each other and perpendicular to the laser emission direction of the laser emission module 4. When the construction worker measures the lighting fixture, the laser emission module is turned on. The laser emitted by the laser emission module can place the device directly below the lighting fixture. In addition, by adjusting the angles of the two laser ranging modules to be perpendicular to the two reference walls respectively, the distances of the lighting fixture relative to the two reference walls can be obtained, and then the position information of the lighting can be obtained, providing the necessary lamp coordinates for the graphical management device.

[0029] Specifically, as Figure 3 shown, a light information receiving and positioning device in this embodiment further includes a key module 5 and a display module 6 arranged on the surface of the housing 1. The output end of the key module 5 is connected to the processor, and the input end of the display module 6 is connected to the processor. Then, through the key module, the light information acquisition process can be started. In addition, the display module 6 can display the status of the device, for example, whether it is turned on, whether the lamp device information or position information is obtained normally, etc.

[0030] Further, in this embodiment, as Figure 4 shown, in this embodiment, there are two laser emission modules 4, and the photosensitive sensor 3 is arranged between the two laser emission modules 4. During operation, the lasers emitted by the two laser emission modules 4 are both aligned with the lighting fixture to form spots on the light-emitting surface of the lighting fixture, which can ensure that the photosensitive sensor (3) can be aligned with the lamp with a relatively high installation position, and then ensure that the light signal sent by the lighting fixture is received.

[0031] Further, as Figure 6 and Figure 7 shown, the photosensitive receiving and amplifying circuit includes: a dual-channel operational amplifier U4, a resistor R10, a resistor R14, a resistor R53, a resistor R6, a resistor R11, and a capacitor C31. The positive electrode of the photosensitive sensor HL3 is connected to the pin -INA of the dual-channel operational amplifier U4, and the negative electrode is connected to the negative power supply; the pin +INA of the dual-channel operational amplifier U4 is grounded, the pin OUTA is connected to the pin -INA through the resistor R10, the pin OUTA is connected to the pin +INB through the resistor R14, the pin -INB is grounded through the resistor R6, the pin -INB is also connected to the pin OUTB through the resistor R53, and the pin OUTB is connected to the input end of the processor; the capacitor C31 is connected in parallel with the R10.

[0032] Further, in this embodiment, there are two laser emission modules. As Figure 8As shown in the figure, the switching circuit includes: transistor Q1, transistor Q2, resistor R17, resistor R18, resistor R19, resistor R20, resistor R21, resistor R22. The base of transistor Q1 is connected to the output terminal of the processor through resistor R17, the emitter is grounded, and the collector is connected to pin K1 of the first laser emission module. Pin A1 of the first laser emission module is connected to the positive power supply through resistor R19, and pin PD1 of the first laser emission module is grounded through resistor R21. The base of transistor Q2 is connected to the output terminal of the processor through resistor R18, the emitter is grounded, and the collector is connected to pin K2 of the second laser emission module. Pin A2 of the second laser emission module is connected to the positive power supply through resistor R20, and pin PD2 of the second laser emission module is grounded through resistor R22.

[0033] The working principle of the present utility model is as follows: During use, the laser emission module emits light, and after irradiating the light-emitting surface of the lamp, spots are formed, which can ensure that the photosensitive component is facing the lamp that is to receive information, that is, the flashing information light emitted by the lamp can reach the photosensitive component directly. By setting the emission cylinder, the light reception angle of the photosensitive component can be restricted, which can avoid the mutual influence of adjacent lamps when sending flashing information light simultaneously, and improve the success rate of reading optical signals. In addition, the photosensitive reception and amplification circuit uses a dual-channel operational amplifier. The photosensitive sensor HL3, resistor R10, capacitor C31 and channel A of the operational amplifier form a transconductance amplification circuit, which converts the current signal output by the photosensitive sensor into a voltage signal. The second-stage amplification circuit is composed of resistor R11, resistor R6, R53 and channel B of the operational amplifier, and its amplification factor is 48 times. Thus, the accurate reception of optical signals can be ensured.

[0034] In summary, the present utility model provides an optical information reception and positioning device. By using the photosensitive sensing and photosensitive reception and amplification circuits to receive the optical signals sent by the illuminating lamp, it can realize the acquisition of device information in the way of optical communication, which has extremely high safety and reliability, greatly simplifies the installation and debugging process of the device. In addition, a positioning module is also provided, which can position the lighting device while obtaining the network address information of the lighting device, facilitating the management of the lighting device by means of a graph in the later stage, and reducing the debugging and management difficulty of intelligent lamps. In addition, the hardware device circuit of the present device is simple, has high safety, is easy to implement, and has wide applicability.

[0035] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: They can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
