DETAILED DESCRIPTION

[0020] See also Figure 1 As shown, the utility model is an intelligent self-checking device for emergency lighting fixtures, comprising an emergency lighting fixture 1, a gateway routing module 2, and a user terminal 3. The emergency lighting fixture 1 comprises an emergency controller 11, a battery module 12, an LED driving power supply 13, an LED light module 14, and a Zigbee module 15;

[0021] The emergency controller 11 is provided with a mains input interface 111, a mains output interface 112, a battery interface 113, a data communication interface 114, an optical module interface 115, and an LED drive interface 116; and the emergency controller 11 is built with an internal LED drive circuit; wherein the battery module 12 is connected to the battery interface 113, and in a non-emergency state the emergency controller 11 charges the battery module 12 and detects the state of the battery module 12, and in an emergency state the battery module 12 supplies power to the emergency controller 11; wherein the LED drive power supply 13 is provided with a mains drive input interface 131, a drive output terminal 132, and a power supply data communication interface 114; the mains output interface 112 is connected to the mains drive input interface 131 of the LED drive power supply 13,

[0022] The power supply data communication interface 114 of the LED driving power supply 13 is electrically connected to the Zigbee module 15 to realize power supply to the dimming circuit inside the Zigbee module 15 and receive the dimming signal from the dimming circuit of the Zigbee module 15. The LED driving power supply 13 outputs the driving electrical signal to the LED driving interface 116 through the driving output terminal 132, and the optical module interface 115 outputs the dimming driving signal (outputs the dimming signal as the dimming driving signal) to the LED optical module 14 according to the driving electrical signal to realize dimming;

[0023] The power supply data communication interface 114 of the LED driving power supply 13 is electrically connected to the Zigbee module 15, so that the Zigbee module 15 can directly control the dimming circuit of the LED driving power supply 13. The user can send a dimming instruction remotely through a mobile phone APP or a server application. After receiving the instruction, the Zigbee module 15 sends a dimming signal to the LED driving power supply 13 through the dimming circuit. After receiving the dimming signal, the LED driving power supply 13 outputs a corresponding driving electrical signal to the LED driving interface 116 through its driving output terminal 132, and the interface further outputs a dimming driving signal to the LED optical module 14 according to these driving electrical signals, so as to realize precise dimming control.

[0024] The Zigbee module 15 is connected to the data communication interface 114 of the emergency controller 11, wherein the emergency controller 11 supplies power to the Zigbee module 15, and the Zigbee module 15 reads information and issues detection instructions to the emergency controller 11; and the user terminal 3 communicates with the Zigbee module 15 through the gateway routing module 2.

[0025] In the intelligent self-test device of the emergency lighting fixture, the Zigbee module 15 is connected to the data communication interface 114 of the emergency controller 11, which not only simplifies the system architecture, but also greatly improves the intelligence and convenience of the system. The emergency controller 11 provides stable power support for the Zigbee module 15 to ensure that it can work normally in various environments. At the same time, the Zigbee module 15, with its excellent wireless communication capability, realizes the accurate reading of the information of the emergency controller 11 and the rapid issuance of detection instructions. The user terminal 3 establishes a communication connection with the Zigbee module 15 through the gateway routing module 2. The user only needs to issue instructions on the terminal device to remotely monitor and manage the emergency lighting fixture. This remote communication method not only simplifies the operation process, but also allows the user to understand the working status of the emergency lighting fixture 1 at the first time, so as to respond in time. In addition, this design also enhances the reliability and stability of the system. Zigbee technology plays a vital role in emergency lighting fixtures with its low power consumption and high reliability. Even in a complex and changeable environment, the Zigbee module 15 can ensure the normal operation of the emergency lighting fixture 1, providing users with more reliable lighting guarantee.

[0026] In general, the entire intelligent detection system consists of three parts: emergency lighting 1, gateway routing module 2, and user terminal 3 (mobile phone or server and APP application). The gateway 21 and router 22, and user terminal 3 (mobile phone or server and APP application) are the tools used by the user, and the emergency lighting 1 is the main body for realizing intelligent detection.

[0027] Specifically, the battery interface 113 of the emergency controller 11 is connected to the battery module 12. When the AC power is normal, in a non-emergency state, the emergency controller 11 will charge the battery module 12 and detect the status of the battery module 12. In an emergency state, the battery module 12 will power the emergency controller 11. The optical module interface 115 (LED+ / LED-) of the emergency controller 11 is connected to the LED optical module 14. The emergency controller 11 has a set of AC power output interfaces 112 (Lout live wire output / Nout neutral wire) outputs, which are connected to the LED driving power supply 13. The driving output end 132 (drive LED+ / drive LED-) of the LED driving power supply 13 is output to the LED driving interface 116 (drive LED+ / drive LED-) of the emergency controller 11. The data communication interface 114 of the emergency controller 11 is connected to the Zigbee module 15, which powers the module and communicates with the Zigbee module 15 through the universal serial port TX / RX, so that the module reads information from the emergency controller 11 and issues detection instructions. The LED driving power supply 13 also has a power supply data communication interface 114 of the Zigbee module 15. In normal state, it will supply power to the dimming circuit of the Zigbee module 15 and receive the dimming signal from the Zigbee module 15, so as to realize the normal lighting dimming control function.

[0028] The Zigbee module 15 uses a 2.4GHz frequency to achieve wireless connection with the gateway 21 through an antenna. The gateway 21 and the router 22 are connected using a network cable. The end user can use WiFi through a mobile phone to connect to the router 22, or use a fixed server terminal to connect to the router 22 through a network cable. The corresponding APP application is installed on the mobile phone or server.

[0029] The Zigbee module 15 uses a frequency of 2.4 GHz to achieve wireless connection with the gateway 21 through an antenna. This wireless connection method is based on the Zigbee communication protocol and has the characteristics of low power consumption, short distance and high reliability. The Zigbee module 15 sends and receives wireless signals through the antenna, establishes a stable communication link with the gateway 21, and realizes the transmission of data and the reception of instructions. The gateway 21 and the router 22 are connected by a network cable, which is a wired connection method that can provide a stable data transmission speed and high reliability. Through the network cable connection, the gateway 21 can transmit the data collected by the Zigbee module 15 to the router 22, and receive instructions or data from the router 22 to achieve communication with the remote terminal.

[0030] The user terminal 3 can connect to the router 22 using WiFi through the mobile phone. Before connecting, the user needs to make sure that the WiFi function of the mobile phone is turned on, and select the same network name (SSID) as the router 22 in the WiFi settings, and enter the correct password to successfully connect. In addition, the user can also use a fixed server terminal to connect to the router 22 via a network cable. This connection method is suitable for scenarios that require higher stability and security. Whether it is a mobile phone or a server terminal, the user needs to install the corresponding APP application. These applications provide interfaces and functions for users to interact with the intelligent self-test device of emergency lighting fixtures. Users can send instructions to the Zigbee module 15 through the APP application to control the brightness and switch status of the LED light module 14; at the same time, the APP application can also receive data from the Zigbee module 15 to display information such as the working status of the lamp and the status of the battery module 12.

[0031] During normal lighting, the emergency controller 11 will control the two ports Lout live output / Nout neutral output to supply power to the LED driver 13. The LED driver 13 will work normally and output LED+ / LED- to the emergency controller 11. The emergency controller 11 will select this group of driver models for the LED light module 14 to light up the LED normally and achieve normal lighting. In an emergency state, the emergency controller 11 will control the two ports Lout live output / Nout neutral output to be closed, and the system will be powered by the battery module 12. The emergency controller 11 will also select the internal LED drive circuit to light up the LED light module 14, and adjust the LED light module 14 to a suitable brightness to maintain sufficient lighting time for the battery module 12.

[0032] Specific working process,

[0033] When the mains power is supplied normally, the emergency controller 11 will control the two ports Lout live wire output and Nout neutral wire output to supply power to the LED driver power supply 13 normally. After receiving the mains power supply from the emergency controller 11, the LED driver power supply 13 will work normally and convert the electric energy into a voltage and current suitable for the operation of the LED light module 14. The LED driver power supply 13 outputs the electric energy to the LED driver interface 116 (drive LED+ / drive LED-) of the emergency controller 11 through its drive output terminal 132 (LED+ / LED-). The emergency controller 11 will select this group of drive signals from the LED driver power supply 13 and output them to the LED light module 14 through its light module interface 115 (LED+ / LED-) to realize the normal lighting of the LED. The user can remotely adjust the brightness of the LED light module 14 through the mobile phone APP or the application on the server terminal to realize normal lighting control.

[0034] In an emergency, the workflow of emergency lighting fixtures will change:

[0035] When the mains power is interrupted, that is, when entering an emergency state, the emergency controller 11 will detect the mains power off signal. The emergency controller 11 will immediately control the two ports, Lout live wire output and Nout neutral wire output, to be closed, and stop supplying power to the LED driver power supply 13. The system will be powered by the battery module 12. The battery module 12 provides power support to the emergency controller 11 through the battery interface 113 of the emergency controller 11. The emergency controller 11 will start its internal LED drive circuit and directly provide power to the LED light module 14. The emergency controller 11 will adjust the LED light module 14 to an appropriate brightness according to the status and remaining power of the battery module 12 to maintain sufficient lighting time for the battery module 12. In an emergency state, the LED light module 14 will continue to emit light to provide lighting for the user and ensure safety and visibility in emergency situations.

[0036] For non-intelligent detection methods, when realizing self-inspection of the emergency lamp 1, it is necessary to press the test button on the emergency controller 11. At this time, the emergency controller 11 will control the closure of the Lout live wire output / Nout neutral wire output to cut off the power supply of the LED driving power supply 13. The driving LED+ / driving LED- on the LED driving power supply 13 also has no output. The emergency controller 11 also switches to the battery module 12 for power supply, and the battery module 12 supplies power to the LED light module and adjusts the brightness of the LED to the brightness of the emergency state. At this time, the discharge time of the battery module 12 is calculated to check whether the maintenance capacity of the battery module 12 meets the requirements.

[0037] However, in the new intelligent emergency lighting system that introduces the Zigbee module 15, the self-test process has become more convenient and intelligent. Users no longer need to press the test button manually, but can issue a self-test command through a mobile phone APP or server application. This process is achieved through the following steps:

[0038] Send a self-check instruction: The user sends a self-check instruction through the APP on the mobile phone or the server application.

[0039] Command forwarding: The command is forwarded to the Zigbee module 15 of the emergency lighting fixture 1 through the router 22 and the gateway 21 .

[0040] Receiving and processing by the Zigbee module 15: After receiving the self-test instruction, the Zigbee module 15 sends the instruction to the emergency controller 11 through the serial port.

[0041] Self-test of the emergency controller 11: After receiving the self-test command, the emergency controller 11 enters the test state and performs self-test operations according to a preset procedure, including shutting down the mains output, switching to the battery module 12 for power supply, adjusting the LED brightness, etc.

[0042] Return detection result: The emergency controller 11 returns the final detection result to the Zigbee module 15 through the serial port.

[0043] Information is returned to the user: the Zigbee module 15 returns the received detection results to the mobile phone application or the server application APP through the gateway 21 for the user to view.

[0044] After the utility model adds the Zigbee module 15 to the original system, the self-test function of the system can be realized without pressing the test button. When a self-test is required, the user sends a self-test instruction through the mobile phone APP or the server application, which is forwarded to the Zigbee module 15 of the emergency lighting 1 through the router 22 and the gateway 21. After receiving the instruction, the Zigbee module 15 sends it to the emergency controller 11 through the serial port, and the emergency controller 11 can enter the detection state and return the final detection result to the Zigbee module 15 through the serial port. The Zigbee module 15 routes the information back to the mobile phone application or the server application APP through the gateway 21.

[0045] The beneficial effects of the overall solution are mainly reflected in the following aspects:

[0046] 1. After the introduction of Zigbee module 15, remote wireless control is realized. Users do not need to go to the site in person to press the test button. They can issue self-test instructions through mobile phone APP or server application, which greatly saves manpower and time costs. The automatic test system of emergency lighting 1 can automatically complete the test of relevant items in the standard, including data analysis and result judgment, thereby greatly improving the efficiency of inspection work. In addition, through the wireless communication method of Zigbee module 15, the system does not need to add additional wiring, reducing wiring costs and maintenance costs.

[0047] 2. The intelligent emergency LED lamps and drivers have integrated intelligence and self-checking functions, which can reduce the burden of monthly testing, reduce maintenance frequency, and thus reduce maintenance costs. The use of LED lighting technology can achieve lower energy consumption and longer service life, further reducing maintenance costs.

[0048] 3. Users can remotely monitor and manage emergency lighting fixtures through mobile phone APP or server applications, and view the working status of the lighting fixtures and the status of the battery module 12 in real time, thereby improving the user experience. In an emergency, the intelligent emergency lighting system can quickly start the emergency lighting equipment to provide necessary lighting support for personnel evacuation and rescue, thus enhancing the user's sense of security.

[0049] 4. Intelligent emergency lighting solutions can automatically adjust the brightness and color temperature of lighting equipment according to ambient light and personnel activities, avoiding energy waste in traditional lighting methods. The use of advanced LED lighting technology can achieve lower energy consumption and longer service life, which is beneficial to energy conservation and environmental protection.

[0050] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
