Description

Technical Field

[0001] The present invention belongs to the field of fire detection alarm display controller loop communication technology, and in particular, relates to a method and system for automatic addressing of fire detection alarm display controller loop equipment. More specifically, it is a fire detection alarm display controller loop equipment automatic addressing technology, in other words, a loop equipment automatic addressing technology. Background Art

[0002] In the fire protection system, loop device addressing technology is a key technology in the fire detection alarm display controller. It involves how to assign unique address codes to the loop devices in the system so that the system can accurately identify and respond to fire alarms, status feedback, control output and other signals.

[0003] There are two common addressing methods for fire detection alarm display controller loop devices, namely electronic encoder addressing and binary dial switch addressing. When the number of loop devices is large, the above two encoding methods require a lot of manpower to manually complete the encoding operation, and the encoding efficiency is low. In addition, when the loop device is repaired or replaced, it is necessary to know the address of the current loop device, which is easy to cause coding errors.

[0004] Patent document CN109377700A discloses a software automatic addressing method and system, which is used to realize that the fire alarm controller in the system automatically encodes the address number of the device node connected to it. The device node adopts a step-by-step series connection method, and is provided with an input end and an output end. The fire alarm controller reads the serial number of the device node and writes the system virtual address according to the serial number. When the device node detects that the virtual address has been written to the local machine, it opens the back end and supplies power to the next cascade node. The automatic addressing method of this patent is not flexible enough. According to the description, it is limited to the step-by-step series connection method, which cannot cope with the complex situations of actual engineering applications; in addition, the addressing method is completed by the CPU. After the addressing is completed, the engineering personnel cannot see the actual address of the loop equipment, which brings new problems to the subsequent maintenance and replacement.

[0005] Patent document CN109035670A discloses a fire alarm system and an address coding method thereof. The scheme sets a broadcast mode to periodically send inspection commands to each addressed unit. The addressed unit without alarm information does not respond to the broadcast information sent by the alarm controller. Only the addressed unit that generates an alarm signal responds to the broadcast information and sends the address code of the addressed unit. At the same time, a full-duplex communication mode is adopted between the addressed unit and the alarm. The alarm controller periodically sends inspection commands. When a fire occurs between the sending of two inspection commands, the addressed unit in the area can actively send the address code of the addressed unit to the alarm controller. This communication method can reduce the response time of the fire alarm, and the alarm controller receives the alarm information quickly. The entire system uses an addressing device to address the addressed units on the bus, which can reduce the error rate of address coding and reduce the number of system debugging steps. However, this address coding method requires additional addressing equipment to be installed on the base, and the addressing equipment needs to be used to address the addressing units on the bus in sequence. This addressing method will consume a lot of manpower to install addressing equipment in medium and large projects with a large number of addressing units. In addition, it still relies on manual addressing, which is prone to address omissions and duplication, thus affecting the progress of the project and rework, resulting in waste of resources and property losses. This problem needs to be solved urgently. Summary of the invention

[0054] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0055] Embodiment 1, the fire detection alarm display controller of the present invention is as follows Figure 1 As shown, it includes: a CPU host module, a loop communication module, a power module, and a touch screen configuration display module.

[0056] CPU host module, fire detection alarm display controller information centralized processing, used for information interaction with loop communication module and touch screen configuration display module;

[0057] The loop communication module is responsible for loop bus communication, collecting loop device information and location information, and reporting to the CPU host module, receiving loop device configuration data information downloaded by the CPU, and automatically addressing the loop devices;

[0058] The power module is responsible for supplying power to the fire detection alarm display controller and loop equipment;

[0059] The touch screen configuration display module is responsible for displaying the status information of the fire detection alarm display controller, showing the electronic layout map of the loop, and configuring the address information of the loop equipment;

[0060] The loop device and the loop communication module communicate in a two-bus manner. The two-bus signal line is led out from the loop communication module and connected to the loop input end of the loop device, and then the loop output end of the loop device is connected to the loop input end of the next loop device, and so on. The entire loop is connected in a ring connection, branch connection or mixed connection mode, such as Figure 2 shown.

[0061] In other words, the loop communication module and the peripheral loop device use two buses to communicate. The entire loop can be connected in a ring connection, a branch connection or a mixed connection. The connection method is diverse and not limited to the step-by-step series connection method, such as Figure 2 shown.

[0062] The types of loop equipment provided by the present invention include: point-type smoke detectors, point-type temperature detectors, point-type smoke-temperature composite detectors, manual fire alarm buttons, input modules, output modules and input-output modules.

[0063] Embodiment 2, based on the fire detection alarm display controller loop device described in the above embodiment, should also include that the loop device uses two sets of loop device addresses, one set is a communication address, and the other set is a user address. The communication address ranges from 1-255, and the user address ranges from 1-500.

[0064] Each of the loop devices described has a unique 4-byte serial number built into it.

[0065] The present invention distinguishes two types of loop communication module address configuration states, one is an unconfigured state, i.e. 0xFF, and the other is a configured state, i.e. 0x01. The configuration state is stored in the loop communication module FLASH, and the state is read and determined each time the loop communication module is powered on or restarted.

[0066] Each loop device of the present invention has a unique 4-byte serial number built in.

[0067] After the loop communication module is powered on or restarted, the loop communication module broadcasts the serial number acquisition preparation instruction "AA 01 01 05" twice.

[0068] The loop communication module broadcasts the command "AA 01 02 05" to check new devices. All loop devices that have not reported serial numbers begin to reply "08". After receiving "08", the loop communication module sends the serial number acquisition command "AA 01 0305". The loop devices that have not reported serial numbers report their serial numbers at the same time. The loop communication module uses an arbitration mechanism to obtain serial numbers and only obtains one serial number at a time.

[0069] Determine if the current loop device data configuration status is 0xFF, and then determine if the communication address already exists, send the communication address modification instruction "AA 06+serial number+05+communication address+05" to modify it to an unused communication address within 1-255, use the communication address acquisition instruction "AA 05+serial number+03 05" to read and confirm that the communication address has been modified, and save it in the SRAM of the loop communication module.

[0070] Determine if the current loop device data configuration status is 0x01, and then determine whether the communication address is the same as the address in FLASH. If not, send the communication address modification instruction "AA 06+serial number+05+communication address+05" to change it to the same communication address, use the communication address acquisition instruction "AA 05+serial number+03 05" to read and confirm that the communication address has been modified, and save it in the SRAM of the loop communication module.

[0071] Send the command "AA 05+serial number+06 05" to obtain the user address, and the loop device will reply with the user address.

[0072] If the current loop device data configuration state is determined to be 0xFF, the user address is saved in the SRAM of the loop communication module.

[0073] Determine if the current loop device data configuration status is 0x01, and then determine if the user address is the same as the address in FLASH. If not, send the user address modification instruction "AA 07+serial number+07+user address+05" to modify it to the same user address, use the user address acquisition instruction "AA 05+serial number+06 05" to read again and confirm that the user address has been modified, and save it in the SRAM of the loop communication module.

[0074] And so on, until all loop device addresses are acquired. So far, the serial number, communication address and user address of the loop device have all been acquired. If the loop device data configuration status is 0x01 at this time, the addressing of all loop devices is completed.

[0075] If the loop device data configuration status is 0x0F, then the drawing of the loop device electronic layout map is completed.

[0076] Send the electronic layout map drawing command "AA 01+communication address+07 05", and the loop device with the same communication address will reply with its own location information after recognizing this command. Repeat the same operation until the location information of all loop devices is obtained.

[0077] The serial number, communication address, user address and location information of all loop devices are uploaded to the touch screen configuration display module to display the electronic layout map of the loop devices.

[0078] According to actual project needs, set the user address of the loop equipment on the electronic layout map of the loop equipment.

[0079] After the setup is completed, the modified serial numbers, communication addresses, user addresses and location information of all loop devices are downloaded to the loop communication module.

[0080] After receiving the loop device information, the loop communication module restarts and repeats the above operation, first obtaining the serial number, then obtaining the communication address and user address. If it is found that the communication address and user address are different, they are modified until all loop devices are scanned and the loop devices are encoded.

[0081] When the loop equipment is operating normally, replace the loop equipment and perform addressing operations on the loop equipment.

[0082] After replacement, the loop communication module sends the new device check command "AA 01 02 05", and the newly replaced loop device replies "08". After receiving 08, the loop communication module sends the serial number acquisition command "AA 01 03 05" to return the serial number of the newly replaced loop device. After obtaining the serial number, the loop communication module sends the communication address acquisition command "AA 05+serial number+04 05" to obtain the communication address of the newly replaced device. At this time, it is determined whether the communication address is repeated with the communication address stored in FLASH. If it is repeated, the communication address modification command "AA 06+serial number+05+communication address+05" needs to be sent to modify it to an unused command.

[0083] Send the electronic map drawing command "AA 01+communication address+07 05", determine the location of the replaced loop device according to the replied location information, directly use the address modification command to write the address information of the replaced device at that location into the replaced loop device, and update the loop device information of the FLASH in the loop communication module at the same time.

[0084] Example 3, the fire detection alarm display controller loop device automatic addressing method of the present invention, when the loop communication module is not configured, that is, 0xFF, such as Figure 3 As shown, the following steps are included:

[0085] (1) After the loop communication module is powered on, the loop communication module broadcasts the serial number acquisition preparation instruction "AA 010105" twice in succession.

[0086] (2) The loop communication module broadcasts the command "AA 01 02 05" to check for new devices. All loop devices that have not reported their serial numbers begin to reply with "08". After receiving "08", the loop communication module sends the command "AA 010305" to obtain the serial number. The loop devices that have not reported their serial numbers report their serial numbers at the same time. The loop communication module uses an arbitration mechanism to obtain the serial number and only obtains one serial number at a time.

[0087] (3) The loop communication module sends the communication address acquisition instruction “AA 05+serial number+04 05”, and the loop device replies with the communication address.

[0088] (4) If the communication address already exists, send the communication address modification instruction "AA 06+serial number+05+communication address+05" to modify it to an unused communication address within 1-255, use the communication address acquisition instruction "AA 05+serial number+0305" to read and confirm that the communication address has been modified, and save it in the SRAM of the loop communication module.

[0089] (5) Send the command to obtain the user address "AA 05+serial number+06 05", the loop device replies with the user address and saves the user address in the SRAM of the loop communication module.

[0090] (6) And so on, until all loop device addresses are acquired.

[0091] (7) Next, the electronic layout map of the loop equipment is drawn. The map drawing command "AA 01+communication address+07 05" is sent. After the loop equipment with the same communication address recognizes this command, it replies with its own location information. Repeat the same operation until the location information of all loop equipment is obtained.

[0092] (8) The serial number, communication address, user address and location information of all loop devices are uploaded to the touch screen configuration display module to display the electronic layout map of the loop devices.

[0093] (9) According to the actual project needs, set the user address of the loop equipment on the electronic layout map of the loop equipment.

[0094] (10) After the setting is completed, the modified serial number, communication address, user address and location information of all loop devices are downloaded to the loop communication module.

[0095] Example 4, the fire detection alarm display controller loop device automatic addressing method of the present invention, based on the above embodiments, when the loop communication module is configured, that is, 0x01, such as Figure 3As shown, the following steps are included: (1) After the loop communication module is powered on, the loop communication module broadcasts and sends the serial number preparation instruction "AA 01 01 05" twice.

[0096] (2) The loop communication module broadcasts the command "AA 01 02 05" to check for new devices. All loop devices that have not reported their serial numbers begin to reply with "08". After receiving "08", the loop communication module sends the command "AA 010305" to obtain the serial number. The loop devices that have not reported their serial numbers report their serial numbers at the same time. The loop communication module uses an arbitration mechanism to obtain the serial number and only obtains one serial number at a time.

[0097] (3) The loop communication module sends the communication address acquisition instruction “AA 05+serial number+04 05”, and the loop device replies with the communication address.

[0098] (4) Determine whether the communication address is the same as the address in FLASH. If not, send the communication address modification instruction "AA 06 + serial number + 05 + communication address + 05" to change it to the same communication address. Use the communication address acquisition instruction "AA 05 + serial number + 03 05" to read and confirm that the communication address has been modified and save it in the SRAM of the loop communication module.

[0099] (5) Send the command “AA 05+serial number+06 05” to obtain the user address, and the loop device replies with the user address.

[0100] (6) Then determine whether the user address is the same as the address in FLASH. If not, send the user address modification instruction "AA 07+serial number+07+user address+05" to modify it to the same user address, use the user address acquisition instruction "AA 05+serial number+06 05" to read and confirm that the user address has been modified, and save it in the SRAM of the loop communication module.

[0101] (7) And so on, until all loop device addresses are acquired. So far, the serial number, communication address and user address of the loop device have all been acquired. All loop devices are addressed.

[0102] Example 5, the fire detection alarm display controller loop device automatic addressing method of the present invention, when the loop device is in normal process, if the loop device fails and needs to be replaced, it is necessary to re-address the replaced loop device, such as Figure 4 As shown, the specific steps include the following steps.

[0104] (2) Send the serial number acquisition command "AA 01 03 05" to obtain the serial number of the newly replaced loop device.

[0105] (3) The loop communication module sends the communication address acquisition command "AA 05+serial number+04 05" to obtain the communication address of the newly replaced device.

[0106] (4) Determine whether the communication address is the same as the communication address stored in FLASH. If it is the same, send a communication address modification instruction “AA 06+serial number+05+communication address+05” to modify it to an unused communication address.
