Description

Technical Field

[0001] The invention relates to a fire emergency lamp registration method and a fire emergency lighting control system applying the method. Background Art

[0002] In the current fire emergency lighting control system, an emergency power supply connects and manages hundreds of lamps through the fire bus. How can the emergency power supply actively discover and search for the actual emergency lamps connected below? Currently, most manufacturers use the following methods: Step 1: Use the coding device on site to write a unique address code for each emergency lamp under the power supply; Step 2: Connect to the centralized power source through a light search software on the computer (via wired or wireless mode); Step 3: In the light search software interface, let the user enter the address number segment of the light to be searched, and then send the light search command to the address codes in the segment one by one in the order of small to large addresses; Step 4: If a lamp in a certain address responds to the lamp search command, it means that there is a lamp at the address code. The centralized power supply records and stores the lamp. At this time, the lamp is connected to the network. If no lamp responds, it means that there is no lamp at the address code. Repeat the third step to search for the next lamp. When all the addresses in the address code segment have sent the lamp search command, the lamp search process ends.

[0003] This method has the following problems: 1. The lamps need to be coded on site. The address code is manually operated, which is prone to duplicate codes. This results in the number of devices being inconsistent with the actual number when searching for lamps. The debugging personnel need to find devices with duplicate codes, which is inconvenient for on-site debugging. 2. The manufacturer needs to provide additional equipment for lamp coding, and the lamp search process is complicated, requiring the manufacturer's professional technical support personnel to come to the site for operation; 3. The address number segments of lamps may not be continuous, and the number segments that are not in the middle also need to occupy the lamp search time, and the entire lamp search process takes too long.

[0004] In addition, the state requires that the destination of fire emergency lighting can be traced, and each lighting fixture needs to be affixed with a fire QR code. In order to meet the traceability requirements, manufacturers also need to make an additional software that matches their own address code with the fire QR code. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems and to provide a fire emergency lighting registration method which is simple, efficient and can automatically register, and a fire emergency lighting control system using the method.

[0006] In order to achieve the above-mentioned object, the technical solution adopted by the present invention is to provide a fire emergency lamp registration method, which is applied to a fire emergency lighting control system, wherein the fire lighting control system includes a centralized power supply as a controller and at least one fire emergency lamp physically connected to the centralized power supply through a fire bus, and is characterized in that the method includes the following steps: Step S1: the centralized power supply sends a light search broadcast packet on the fire bus; Step S2: All the fire emergency lamps that are not connected to the network upload their own address codes to respond to the light search broadcast package after receiving the light search broadcast package; Step S3: arbitrating the address codes sent by the fire emergency lamps to obtain arbitration results; Step S4: Determine whether there is a lamp connected to the network according to the arbitration result. If yes, the arbitration result is the address code of the fire emergency lamp connected to the network this time, and proceed to step S5. If no, the whole registration process ends. Step S5: the emergency power supply registers the fire emergency lighting fixture corresponding to the address code in the arbitration result, and sends a registration success command to the address code point-to-point; Step S6: The fire emergency lighting fixture that has received the registration success command sends a response to the emergency power supply, and sets itself to the networked state, and no longer participates in the subsequent registration process.

[0007] Step S7: Continue to repeat step S1.

[0008] Preferably, the arbitration result in step S4 is the minimum value of the address codes of all the fire emergency lamps participating in the arbitration.

[0009] Preferably, the arbitration method in step S4 is wired-AND arbitration.

[0010] Preferably, the specific method of the line-and arbitration is to arbitrate the address code sent by each fire emergency lamp to the fire bus bit by bit, starting from the highest bit, the fire emergency lamp that sends a low level is retained, the fire emergency lamp that sends a high level exits the arbitration, and then continues the arbitration of the next bit, and finally retains the smallest address code on the fire bus as the arbitration result.

[0011] Preferably, before step S1, the method further includes step S0 in which the centralized power supply sends a broadcast packet of invalid registration of lamps, and all the fire emergency lamps set themselves to a non-networked state after receiving the broadcast packet of invalid registration.

[0012] Preferably, it is characterized in that the address code of the fire emergency lighting fixture is the fire code of the fire emergency lighting fixture.

[0013] Preferably, when the fire emergency lighting fixture leaves the factory, the fire code is pre-written into the fire emergency lighting fixture as the address code of the fire emergency lighting fixture.

[0014] The present application also provides a fire emergency lighting control system, including a centralized power supply as a controller and at least one fire emergency lamp physically connected to the centralized power supply through a fire bus, characterized in that the fire emergency control system adopts the fire emergency lamp registration method as described above to register the lamps.

[0015] Preferably, the fire emergency lighting fixture is pre-written with a fire code when it leaves the factory, and the fire code is the address code of the fire emergency lighting fixture.

[0016] In the fire emergency lighting registration method provided by the present invention, the emergency power supply actively sends a light search broadcast package when searching for lights, and all unregistered emergency lamps connected to the power supply will respond after receiving the command. The emergency power supply preferentially searches for the emergency lamp with the smallest address code through line and arbitration, records and registers the lamp, and the lamp records itself as having been connected to the network. The next time the emergency power supply searches for lights, it will not respond, and will not affect the fire bus. In this way, all lamps will be searched and registered under the emergency power supply in a reciprocating cycle. The whole process does not require manual intervention, which is convenient and efficient. At the same time, the fire code is used as the address code, and the address code and the fire code are unified, realizing one code for one item, which facilitates subsequent logistics tracking. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a flow chart of a fire emergency lighting registration method according to a preferred embodiment of the present invention. Implementation

[0018] The fire emergency lighting registration method and the fire emergency lighting control system proposed by the present invention are further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A fire emergency lighting control system provided in a preferred embodiment of the present application includes a centralized power supply as a controller and at least one fire emergency lamp physically connected to the centralized power supply through a fire bus. Fire emergency lamps are affixed with a fire code in the form of a QR code according to national regulations when leaving the factory. The fire emergency lamps in this embodiment are affixed with a fire QR code (7 bytes) when the whole machine is tested at the factory. The whole machine detection software reads the QR code through a scanner gun to obtain the fire code, and writes the fire code into the lamp through a special tool as the address code of the lamp for subsequent registration and network access. This can save the trouble of on-site coding. In other preferred embodiments, when it is necessary to use the fire emergency lamp registration method described in this application, the fire code can be read by a specific device and then written into the lamp. This application does not limit this.

[0020] The fire emergency control system in this embodiment adopts Figure 1 The registration method shown is used to register the lamps connected to the bus, and specifically includes the following steps: Step S0: The centralized power supply sends a broadcast packet indicating that the lamp registration is invalid. After receiving the broadcast packet indicating that the lamp registration is invalid, all the emergency lamps connected to the fire bus set themselves to a non-networked state and can be networked. The sending of the invalid broadcast packet can be triggered manually on the centralized power supply or by sending a remote command.

[0021] Step S1: The centralized power source sends a light search broadcast packet on the fire bus, and the registration process begins at this time.

[0022] Step S2: After receiving the light search broadcast packet, all fire emergency lamps that are not connected to the network respond by uploading their own address codes at a certain time and wait for arbitration.

[0023] Step S3 arbitrates the address codes sent by each fire emergency lamp to obtain the arbitration result. The arbitration method in this embodiment is line AND arbitration. When executing line AND arbitration, the bus is initially high, and each access device outputs a signal. As long as any device on the bus outputs a low level, the bus remains at a low level. While each access device outputs a signal, it receives high and low level signals on the bus. When the input and output signals are inconsistent, that is, when the bus signal received by the device that sends a high level is a low level, according to the arbitration, it will not continue to send signals and exit this arbitration. As mentioned above, the fire code in this embodiment contains 7 bytes. When arbitrating, the address code sent by each fire emergency lamp to the fire bus is line AND arbitration bit by bit. Starting from the highest bit, the fire emergency lamp that sends a low level is retained according to the line AND arbitration rules, and the fire emergency lamp that sends a high level exits this arbitration. Then continue the arbitration of the next bit. When each bit is arbitrated, the smallest address code among the address codes participating in the arbitration is retained on the fire bus, and the smallest address code is the arbitration result. When there are no fire emergency lamps that are not connected to the network, all bits on the bus maintain a high level. After a period of time, this state is the arbitration result.

[0024] Step S4 determines whether there are lamps connected to the network based on the arbitration result. If there are lamps that have not been connected to the network on the bus, the arbitration result is the smallest address code among the address codes participating in the arbitration. At this time, it is determined that there are lamps connected to the network. The arbitration result on the bus is the address code of the fire emergency lamp that has been connected to the network this time, and then proceed to step S5. When the bus signal as the arbitration result is read, it is found that all bits are high level, indicating that no lamps participate in the arbitration, and there are no fire emergency lamps that are not connected to the network on the bus, and the entire registration process ends at this time.

[0025] Step S5: The emergency power supply registers the fire emergency lamp corresponding to the address code in the arbitration result, and the centralized power supply records and stores the lamp. At the same time, a registration success command is sent point-to-point to the address code.

[0026] Step S6: After receiving the successful registration command, the fire emergency lighting fixture corresponding to the address code in this arbitration result sends a response to the emergency power supply, and sets its own status to the networked status, and no longer participates in the subsequent registration process.

[0027] Step S7: Continue to repeat step S1. When step S1 is executed again, the fire emergency lamps that have been connected to the network will no longer respond when receiving the search light broadcast packet from the emergency power supply, so as to avoid affecting the fire bus. In this way, all lamps will be searched and registered under the emergency power supply in a reciprocating manner until the last lamp is registered, and then step S1 will be executed. At this time, there are no fire emergency lamps that are not connected to the network on the bus, and the bus arbitration result will remain at a high level. After it is determined that no lamps have joined, the entire registration process ends.

[0028] The above description of the preferred embodiments of the present application is for illustration and description, and is not intended to be exhaustive or limited to the specific form disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included in the scope of the present application defined by the attached claims.
