Description

TECHNICAL FIELD

[0002] The fire control system is a core component of fire safety in key industrial sites such as power plants and substations, and is widely used in fire monitoring and prevention in main transformer areas, generator-transformer group equipment and other high-risk areas. Although the fire control system has been widely used in the industrial field, there are still many deficiencies in the existing technology.

[0003] The control module of the old system often does not support unified management of multiple sub-valve branches, and it is difficult to adapt to the complex fire safety requirements of modern large power plants. The existing system usually only supports single automatic control in the operation mode, and lacks flexible switching function between manual and automatic modes, which limits the intervention ability of the staff in the debugging, maintenance or emergency scene. When it is necessary to control or clear the residual signal of a specific sub-valve, the existing system often cannot provide a convenient operation interface, increasing the difficulty of maintenance. The water flow detection module of some fire control systems has a single function, which can only detect the water flow state of the main pipeline, and lacks detailed monitoring of the test pipeline and fire pipeline, resulting in the inability to comprehensively evaluate the running state of the system.

[0004] Some systems only rely on indicator lights to display fault states, and do not equip audio devices, which cannot effectively prompt the staff in high-noise environments or long-distance scenes. The alarm logic is usually simple, lacks flexible reset mechanism, and cannot cope with complex scenes that require manual intervention.

[0005] Therefore, a fire control system and an alarm regulation method are needed to meet the needs of the existing environment, which can effectively enhance the stability of the equipment and the management of multiple sub-valves, provide flexible operation mode support, automatic control, manual control and signal clearing function, refine water flow monitoring and feedback, and optimize alarm logic and reset mechanism, and supplement the sound and light alarm function.

[0054] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0055] Example 1

[0056] Reference Figs. 1-3 The present embodiment provides a fire control system.

[0057] Example 1 provides a fire control system, which can be used to realize real-time monitoring, rapid response and reliable control of main transformer area fire signals, and is suitable for fire safety protection of key places such as power plants and substations. The fire control system mainly includes a main valve control module 1, a flow detection module 2 and a signal control module 3. Each module can work cooperatively to ensure that the system can quickly and accurately start fire response, control water spraying and extinguish fire sources or suppress fire spread when receiving fire alarm signals or other abnormal signals.

[0058] The main valve control module 1 is the core control unit of the fire control system, which is responsible for receiving and processing control instructions generated by the signal control module 3, and driving the rain valve and other actuators to complete the water spraying action,

[0059] The main valve control module 1 is provided with a relay on-off unit 11, a relay locking unit 12 and an interlocking sub-unit 13. The relay on-off unit 11 can select electromagnetic relay or solid-state relay to meet the on-site demand in this scheme, which is used to control the opening and closing of the rain valve. The relay on-off unit 11 completes the on-off operation of the circuit by receiving the electrical signal finally transmitted from the signal control module 3, so as to realize the start and stop of water spraying.

[0060] When the fire alarm signal is detected, the relay on-off unit 11 can quickly close the circuit to drive the rain valve to open, so as to ensure that the water flow is sprayed to the main transformer area in time.

[0061] The relay locking unit 12 is electrically connected to the relay on-off unit 11 to provide the basic on condition, so as to ensure that the relay remains in the off state under unnecessary conditions and prevent the system from being triggered by mistake due to misoperation.

[0062] The relay locking unit 12 adopts a logic control circuit arranged in series. Only when the relay locking unit 12 is confirmed to be turned on by the upper computer, the relay locking unit 12 can be turned on. Only when the relay locking unit 12 is turned on, the relay on-off unit 11 can continue to operate. When the fire triggering threshold is not reached, the relay locking unit 12 will not receive a starting signal, and thus will not be turned on, preventing unnecessary water flow spraying.

[0063] The interlocking sub-unit 13 is connected to the output end of the main valve control module 1, and can realize the on-off interlocking function inside the relay on-off unit 11. The interlocking sub-unit 13 ensures that when the system performs the opening or closing operation of the deluge valve, the reverse conflict operation is temporarily locked, preventing system state confusion.

[0064] The flow detection module 2 is used to monitor the water flow state in the water flow pipe in real time, and transmit the collected signals to the monitoring end for analysis and processing. One end of the flow detection module 2 is physically connected to the water flow pipe through a flange or a threaded interface, and the other end is connected to a data terminal through a data interface.

[0065] In field application, the flow detection module 2 can detect the water flow data in the water flow pipe. When a fire occurs in the main transformer area, after the deluge valve is opened, the flow detection module 2 detects that the water flow speed increases significantly, and immediately uploads the signal. Whether the fire response is normal can be judged according to the preset logic, thereby ensuring the effective operation of the system.

[0066] The signal control module 3 is the signal processing and logic decision center of the system, responsible for receiving external operation signals and generating corresponding deluge valve output signals. The signal control module 3 transmits control instructions to the executive mechanism through the main valve control module 1 to adjust the water flow spraying state. The signal control module 3 is usually integrated in an industrial computer or an embedded controller, and supports multiple input signal types.

[0067] The signal control module 3 also supports manual reset and mute operation. The staff can stop the alarm by clicking the mute key on the touch screen, or restore the system to the initial state by pressing the reset key, thereby facilitating fault diagnosis and system maintenance.

[0068] Through the relay locking unit 12 and the interlocking sub-unit 13 in the main valve control module 1, the system can effectively prevent misoperation and state conflict, improve the stability and safety of the system operation; the flow detection module 2 can collect the water flow state in real time and feedback, which facilitates the staff to find pipeline abnormalities or spraying state abnormalities in time, shortens the fault response time, and the signal control module 3 supports multiple signal inputs and manual operation, adapts to the needs of different fire scenes, and provides a reset function to facilitate system maintenance.

[0069] Embodiment 2

[0070] Referring to Figs. 1-5 , the embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0071] The main valve control module 1 is fixedly provided with an on-off total unit 14 on the basis of the original embodiment. The on-off total unit 14 is used to uniformly control the on-off units 11 of the relays in all sub-valve branches. The on-off total unit 14 adopts a centralized control circuit mode to connect each sub-valve branch by using a parallel or serial bus. Since there is more than one deluge valve, this connection mode ensures that the main valve control module 1 can simultaneously manage multiple deluge valves or spray actuators, and realize global start-stop synchronization.

[0072] Each relay on-off unit 11 is provided with a switching quantity output unit 111 and a normally open unit 112 in parallel. The switching quantity output unit 111 is responsible for providing digital signal output switching signals for driving external actuators. The normally open unit 112 is designed with normally open contacts to ensure that it remains in an open state when there is no signal, preventing accidental spraying, and can also be used for manual intervention.

[0073] The output ends of the relay on-off unit 11, the switching quantity output unit 111, and the normally open unit 112 are collectively connected to the interlocking sub-unit 13, forming multi-channel signal aggregation and realizing unified interlocking management of the on-off state.

[0074] The sub-units of the relay on-off unit 11 are divided into a relay start sub-unit 113 and a relay close sub-unit 114, corresponding to the start and close sub-circuits respectively. The relay lockout unit 12 is provided on the start sub-circuit between the relay start sub-unit 113 and the interlocking sub-unit 13, and assists in providing a safety lockout function.

[0075] Only when the relay lockout unit 12 is connected, the relay start sub-unit 113 in the relay on-off unit 11 can continue to operate. When the fire trigger threshold is not reached, the relay lockout unit 12 will not receive a start signal, and therefore will not be connected, preventing unnecessary water flow spraying.

[0076] When the system detects a lockout signal, the lockout unit 12 will interrupt the start sub-circuit to prevent forced starting in a fault state, thereby enhancing the system's anti-misoperation capability.

[0077] The signal control module 3 further refines the signal receiving and processing logic compared to the embodiment 1, and introduces a remote start-stop receiving unit 31, a lockout control receiving unit 32, a main valve signal receiving unit 33, and a start mode selection receiving unit 34 to support remote control, lockout diffusion, and multi-mode operation.

[0078] The remote start-stop receiving unit 31 is used to provide the bottom layer opening and closing logic of the system, access the on-off total unit 14 through wireless or wired network, and realize the remote monitoring station to control the start-stop of the main valve. The lock control receiving unit 32 can provide a diffusion lock function for the relay start sub-unit 113, electrically access the relay lock unit 12, ensure that the lock signal can be expanded to multiple sub-valve branches, and also can avoid the influence of local failure on the whole. The main valve signal receiving unit 33 is electrically connected with the relay on-off unit 11, provides the on-off signal input of all sub-valve branches, supports multi-channel parallel processing, and improves the throughput of signal processing.

[0079] The start mode selection receiving unit 34 includes a clear sub-unit 341, an automatic sub-unit 342 and a manual sub-unit 343, which allows the on-site technician to select the operation mode according to the scene. The clear sub-unit 341 accesses the relay on-off unit 11, provides a signal clear reset function, and is used to cope with the residual or residual signal of water flow in the valve, to ensure that there is no additional interference after the system is reset.

[0080] After the spraying is finished, the clear sub-unit 341 can manually clear the residual water pressure signal to prevent false alarms. The automatic sub-unit 342 is electrically connected to the automatic control branch of the relay on-off unit 11, provides a unified automatic start-stop signal input, and the manual sub-unit 343 is connected to the manual control branch, provides independent manual start-stop signal input of each sub-valve, and is convenient for technicians to carry out on-site debugging or emergency operation.

[0081] The output end of the signal control module 3 accesses the output control module 4, which can control the motor to act after receiving the output command of the signal control module 3, so as to drive the main valve control module 1 and the flow detection module 2 to operate.

[0082] The motor can adopt a general servo motor or a stepping motor, only need to ensure accurate valve opening adjustment. The main valve control module 1 and the flow detection module 2 generate action and fault feedback signals under the drive, and enter the monitoring module 5.

[0083] In the scheme, the monitoring module 5 adopts upper computer software, can display system state, alarm log and fault diagnosis in real time, supports data storage and remote access, and is convenient for subsequent analysis and optimization.

[0084] The flow detection module 2 is subdivided into a water pipe flow detection unit 21 and a fire pipe flow detection unit 22, which can realize independent monitoring of different water flow paths. The water pipe flow detection unit 21 monitors the water flow for test pipes such as water pipes, the input end accesses the actual water flow position detection, and the output end accesses the data terminal to upload signals into the monitoring module 5. The water pipe flow detection unit 21 can be used for system self-checking to ensure that the pipeline is not leaking or blocked.

[0085] The flow indication unit 22 of the fire pipe monitors the state of the water flow using a sensor configuration for the main fire pipe. The output signals of the two units support 4-20mA or digital protocol transmission, which facilitates integration into the monitoring module 5 for real-time analysis.

[0086] In fire response, the fire pipe flow indication unit 22 can immediately feedback to the signal control module 3 when it detects an abnormal water flow, triggering the locking or alarm mechanism.

[0087] In the entire operation process, the first step is mode selection and signal reception. First, the system selects the automatic mode through the start mode selection receiving unit 34, the remote start-stop receiving unit 31 receives the remote fire signal or start signal, and the main valve signal receiving unit 33 collects the sub-valve state.

[0088] Then, the control and execution process is performed. The signal control module 3 generates corresponding opening commands, the on-off total unit 14 uniformly drives the relay on-off unit 11, the relay start sub-unit 113 acts, and the locking control receiving unit 32 ensures no conflict.

[0089] In the water flow monitoring and feedback process, the water flow detection module 2 monitors the water flow in real time, the output control module 4 drives the motor to adjust the valve, and the feedback signal enters the monitoring module 5.

[0090] Finally, the reset and zeroing are performed. After the response is completed, the zeroing sub-unit 341 resets the signal, the relay off sub-unit 114 disconnects the circuit, and the system returns to the initial state.

[0091] The introduction of the on-off total unit 14 and the start mode selection receiving unit 34 supports multi-mode and multi-sub-valve management, effectively improving the flexibility and adaptability of the system, and is suitable for complex fire layout of large power plants. The locking control receiving unit 32 and the interlocking sub-unit 13 can prevent fault propagation, reduce the risk of misoperation, and ensure stable operation in high-pressure or multi-signal environments. The subdivision unit of the flow indication detection module 2 provides accurate water flow feedback, combined with the monitoring module 5, realizes rapid fault positioning and data visualization, thereby shortening the response time and reducing maintenance costs.

[0092] Embodiment 3

[0093] Referring to Figs. 1-7 , this embodiment is based on the previous embodiment, and differs from the previous embodiment in that:

[0094] The present embodiment provides an alarm control method suitable for fire safety management in key places such as power plants and substations.

[0095] The alarm regulation method can mainly perform alarm logic debugging after system replacement, verify the action and reset function of the alarm under various signal scenarios, and ensure that the system can monitor abnormalities in real time and respond quickly. The debugging process combines double adjustment mode, allowing automatic or manual operation to meet the operation needs in different scenarios, improving the flexibility and practicality of the system.

[0096] Before implementing the alarm regulation method, the original fire control system needs to be replaced as a whole to ensure that the hardware supports the sound and light alarm function. The replaced system includes a main valve control module 1, a flow detection module 2, a signal control module 3, and an output control module 4 and a monitoring module 5, and according to the structure of claim 2, the on-off total unit 14, the on-off output unit 111, the normally open unit 112 and other components are configured. These hardware modules provide a basis for alarm logic debugging, ensuring reliable signal reception, processing and feedback.

[0097] Check the wiring integrity of the relay on-off unit 11 and the on-off output unit 111, the normally open unit 112 in the main valve control module 1 to ensure that the signal path is smooth.

[0098] After confirming that the signal control module 3 is normally connected with the communication interface of the upper computer and supports signal input and output, then calibrate the sensing part of the flow detection module 2 to ensure that it can accurately detect the water flow state and upload it to the monitoring module 5. Finally, configure the electrical connection between the alarm and the signal control module 3 to ensure that the sound and light alarm function is normal.

[0099] Alarm logic debugging is the core step of this method, which verifies the alarm response capability and reset function of the system by simulating various key signals. The debugging process tests the following four signals: fire alarm signal of the fire control host, generator / main transformer differential signal of the generator / transmission group A / B cabinet, heavy gas signal, and low voltage side pressure loss signal of the main transformer.

[0100] During the debugging process, use the signal generator or the upper computer to simulate the following signal inputs to the signal control module 3: simulate the main transformer area fire scenario and send high priority on-off signal; simulate the generator or main transformer differential protection action and send differential abnormal signal; simulate the internal heavy gas protection trigger of the transformer and send analog or on-off signal; simulate the main transformer low voltage side pressure loss scenario and send voltage abnormal signal.

[0101] For each signal, the signal control module 3 generates corresponding alarm instructions after receiving it. During debugging, the monitoring module 5 records the alarm action time, signal type and intensity in real time to ensure that each signal input triggers the correct response. When simulating the fire alarm signal of the fire control host, the alarm should act within 1 second, the yellow fault indicator light should be lit simultaneously, and there should be no delay or false alarm.

[0102] The alarm regulation method supports a double adjustment mode, allowing to realize the reset operation through automatic or manual mode after the alarm action, so as to meet the operation requirements in different scenes.

[0103] Mode one is automatic reset;

[0104] When the analog signal action ends, the signal control module 3 detects the signal state change and generates a reset instruction. The reset instruction is transmitted to the alarm through the relay on-off unit 11 of the main valve control module 1, and the yellow fault indicator light is turned off, indicating that the system state returns to normal. The automatic reset mode is suitable for unattended or high automation scenarios, and the response time from signal end to reset completion needs to be verified during debugging to ensure efficient system reset.

[0105] Mode two is manual reset;

[0106] When the alarm is activated and the yellow fault indicator light is on, the staff can manually operate through the upper computer interface.

[0107] Click the mute key on the upper computer interface, and the signal control module 3 generates a mute instruction, and the sound device stops the alarm sound, but the yellow fault indicator light remains on, indicating that the fault still needs to be handled. This step is convenient for reducing noise interference in the continuous alarm scene and maintaining the on-site work order.

[0108] After confirming that the fault handling is completed, press the reset key on the upper computer interface, and the signal control module 3 generates a reset instruction, the alarm is completely reset, the yellow fault indicator light is turned off, and the system returns to the initial state.

[0109] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
