DETAILED DESCRIPTION
[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.
[0018] like Figure 1 As shown, a specific embodiment of the present invention discloses a loop device address encoding method, including: S101, when receiving a scan command sent by a fire alarm controller, perform a device scan according to the scan command to obtain information of all online devices; S102, performing duplicate code detection based on all online device information to determine the device allocation mode; S103, when the device allocation mode is the full-loop device allocation mode, allocating addresses to all online device information according to a preset total address pool to obtain a new address for each online device; S104. When the device allocation mode is the re-encoding device allocation mode, addresses are allocated to the re-encoding devices in all online device information according to a preset total address pool to obtain a new address for each re-encoding device.
[0019] It should be understood that the loop board is a board installed on the fire alarm controller, which is used to detect the status of each loop in the system and to alarm in time when the loop fails. The loop board monitors and controls fire detection, fire sprinkler, sound and light alarm and other equipment by connecting detectors or modules and other equipment, and is an important part of the fire protection system. The loop board can realize the bus loop (alarm linkage bus), each loop supports a certain number of address points, can connect a certain number of loop devices, encode according to the address, and each loop device occupies an address point. Various detectors (smoke fire detectors or heat fire detectors), manual alarm buttons, fire alarm buttons, modules, and sound and light alarms with address coding can be connected in parallel to the bus loop board. By increasing the number of loop boards, the capacity of the controller can be expanded. In the fire alarm system, each loop device has a unique address code in the system through the location of the loop board and the address point of the loop board where it is located. When a fire occurs, the alarm signal of the fire triggering device is fed back to the fire alarm controller through the bus. The controller identifies the loop number and address point of the alarm device through this loop device, sends out a control signal according to the set control logic, and sends out control instructions to the output module device or coded sound and light alarm of the specified loop and address point to realize the system function.
[0020] In a specific embodiment of the present invention, in a fire alarm system, the loop device is connected to the loop board in parallel, and the loop board is connected to the loop device, such as a common Figure 2 There are 6 types of module devices shown. Figure 2The fire alarm controller in the system may include a mainboard card, and may also display output and control output through key input and touch screen input. The fire alarm controller may be connected to loop boards 1-N, and each loop board may be connected to devices such as smoke fire sensors, temperature fire sensors, manual alarm buttons, fire alarm buttons, input and output modules, and sound and light alarms. A preset total address pool may be set according to actual conditions. When performing the embodiment of the present invention, the preset total address pool may be obtained. The fire alarm controller may send a scan command to the loop board. When the loop board receives the scan command sent by the fire alarm controller, it may scan the devices under the loop, and then return the obtained online device information to the fire alarm controller. The fire alarm controller may obtain the online device information of each loop board, and then obtain all online device information. Then, the fire alarm controller may perform re-code detection on all online device information, and determine the device allocation mode. When the device allocation mode is the full loop device allocation mode, all online device information may be allocated addresses through the addresses in the preset total address pool, so that each online device may obtain a new allocated address. When the device allocation mode is the re-code device allocation mode, addresses of re-code devices in all online device information can be allocated through a preset total address pool, so that each re-code device can obtain a new allocated address.
[0021] Compared with the prior art, the present embodiment provides that when a scan command sent by a fire alarm controller is received, a device scan is performed according to the scan command to obtain all online device information, thereby automatically completing the device scan and obtaining all online device information; further, a duplicate code detection is performed based on all online device information to determine the device allocation mode. When the device allocation mode is a full-loop device allocation mode, addresses are allocated to all online device information based on a preset total address pool to obtain a new address for each online device; when the device allocation mode is a duplicate code device allocation mode, addresses are allocated to all duplicate code devices in the online device information based on a preset total address pool to obtain a new address for each duplicate code device; thereby, corresponding addresses can be allocated to devices according to different device allocation modes without manual setting, thereby improving the efficiency and time of device address setting and reducing the error rate.
[0022] In some embodiments of the present invention, all online device information includes the original address of each online device; Figure 3 As shown, step S102 includes: S301, judging whether there is a device with a duplicate address according to all original addresses of all online devices in all online device information; S302: If yes, determine that the device allocation mode is a re-coding device allocation mode; S303: If not, determine that the device allocation mode is the full-loop device allocation mode.
[0023] In a specific embodiment of the present invention, after obtaining all online device information, all original addresses of all online devices in all online device information can be analyzed to determine whether there is a duplicate address device. If so, the device allocation mode can be determined to be the duplicate address device allocation mode. If not, the device allocation mode can be determined to be the full-loop device allocation mode, wherein the algorithm uses a hash table algorithm to determine whether there are devices with duplicate addresses among all online devices. If there are duplicate address devices, they are screened out and used for the duplicate address device allocation mode.
[0024] In some embodiments of the present invention, step S103 includes: Sort the devices according to the original address of each online device to obtain the loop device sequence; An address is allocated to each online device according to a preset total address pool and a loop device sequence to obtain a new address for each online device.
[0025] In a specific embodiment of the present invention, when the device allocation mode is a full-loop device allocation mode, all online devices can be sorted in ascending order according to all original addresses of all online devices in all online device information to obtain a loop device sequence, and then an address can be allocated to each online device according to the arrangement order of the addresses in the preset total address pool and the loop device sequence, so that a new address for each online device can be obtained.
[0026] In some embodiments of the present invention, allocating an address to each online device according to a preset total address pool and a loop device sequence to obtain a new address for each online device includes: Determine the initial address based on the preset total address pool; Starting from the initial address in the preset total address pool, the addresses of the online devices in the loop device sequence are allocated one by one in an address increment manner to obtain a new address for each online device.
[0027] In a specific embodiment of the present invention, the initial address in the preset total address pool can be determined according to actual conditions. The initial address can be the first address that needs to be assigned an address, so that starting from the initial address, the online devices in the loop device sequence can be assigned addresses one by one in an address incrementing manner according to the order of the online devices in the loop device sequence, and a new address for each online device can be obtained. For example, the preset total address pool can be 1-225. When the initial address is 1, it can be determined that the first online device in the loop device sequence is assigned from 1, then the new address of the first online device is 1, and the addresses are assigned by adding 1 in sequence, then the new address of the second online device is 2, and so on, until the last online device. Among them, after the fire alarm controller receives all the online device information, it can send a write address command to the loop board, and the loop board automatically rewrites the new addresses of the scanned online devices in batches.
[0028] In some embodiments of the present invention, Figure 4 As shown, step S104 includes: S401, filter all online device information to obtain all duplicate code devices; S402, obtaining an unused address pool according to a preset total address pool and information of all online devices; S403, allocating addresses to all re-coding devices according to the unused address pool to obtain a new address for each re-coding device.
[0029] In a specific embodiment of the present invention, when the device allocation mode is a duplicate code device allocation mode, the original address of each online device in all online device information can be filtered through an address filtering algorithm to obtain all duplicate code devices. The specific processing process of the address filtering algorithm can be: the addresses in the preset total address pool can be analyzed with the original addresses of all online device information to obtain an unused address pool, and then the addresses of all duplicate code devices can be allocated one by one through the unused address pool to obtain a new address for each duplicate code device.
[0030] In some embodiments of the present invention, step S402 includes: Analyze and process all online device information according to the preset total address pool to obtain all unique and used addresses; The preset total address pool is screened according to all addresses to obtain an unused address pool.
[0031] In a specific embodiment of the present invention, the addresses in the preset total address pool can be matched and analyzed with all the original addresses of all online device information to obtain all the non-repetitive addresses in the preset total address pool that are already in use. Then, all the addresses in the preset total address pool can be screened to obtain unused addresses, that is, an unused address pool can be obtained.
[0032] In some embodiments of the present invention, all online device information includes the type and SN number of each online device; step S403 includes: Sort all re-coded devices according to type and SN number to obtain a re-coded device sequence; According to the size of the addresses in the unused address pool, the addresses are allocated to the re-coding devices in the re-coding device sequence in sequence in an address incrementing manner to obtain a new address for each re-coding device.
[0033] In a specific embodiment of the present invention, all online device information may include the type and SN number of each online device. All re-coded devices can be sorted from small to large by type and SN number to obtain a re-coded device sequence. Then, addresses can be allocated to devices in the re-coded device sequence in ascending order according to the size of the addresses in the unused address pool, so that each re-coded device can obtain a new address. After the fire alarm controller receives all the online device information, it can send a write address command to the loop board, and the loop board automatically rewrites the new addresses of the scanned online devices in batches.
[0034] The controller interface of the embodiment of the present invention can scan the loop device and then view the scanning results. Based on the above two different modes, the controller automatically addresses the loop device after software processing and sends write address commands in batches to achieve the effect of setting the address.
