Description

Technical Field

[0001] The invention relates to the technical field of building fire protection facilities, and in particular to a detection method for a gas fire extinguishing system of a building fire protection facility. Background Art

[0002] Building fire protection facilities refer to the general term for equipment and facilities such as automatic fire alarm systems, automatic water sprinkler systems, and fire hydrant systems installed in buildings (structures) for preventing and fighting building (structure) fires. Commonly used ones include automatic fire alarm systems, automatic water sprinkler systems, fire hydrant systems, gas fire extinguishing systems, foam fire extinguishing systems, dry powder fire extinguishing systems, smoke and exhaust systems, and safe evacuation systems. It is an important facility to ensure the fire safety of buildings and the safety of personnel evacuation, and is an important part of modern buildings. It plays an important role in protecting buildings and effectively protects the lives and property of citizens. As an important part of building fire protection facilities, the gas fire extinguishing system is to arrange smoke detectors, gas fire extinguishing agent bottles, gas transmission pipelines, circuits and other equipment in the fire protection area.

[0003] At present, when staff conduct inspection and maintenance on gas fire extinguishing systems after inspection, they usually go to the site and conduct unified inspection and maintenance on the gas fire extinguishing systems in an entire building. This inspection method requires the gas fire extinguishing systems to be checked and repaired one by one. Since the gas fire extinguishing systems at each location in the building require different inspection time intervals due to different environments, it is not only impossible to timely distinguish the gas fire extinguishing systems that need to be inspected and the gas fire extinguishing systems that do not need to be inspected, thereby greatly consuming manpower and increasing labor costs. At the same time, this inspection and maintenance method also greatly reduces the inspection and maintenance efficiency of the staff and is very inconvenient to operate.

[0004] In view of the above problems, a detection method for the gas fire extinguishing system of building fire protection facilities is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a detection method for the gas fire extinguishing system of a building fire protection facility. The device is used to work, thereby solving the problem that in the above-mentioned background, when the staff detects the gas fire extinguishing system and repairs it after the detection, they usually go to the site and perform unified maintenance on the gas fire extinguishing system in the entire building. This detection method requires the gas fire extinguishing system to be checked and repaired one by one. Since the gas fire extinguishing system at each location in the building requires maintenance at different time intervals due to different environments, it is not only impossible to timely distinguish the gas fire extinguishing system that needs maintenance and the gas fire extinguishing system that does not need maintenance, thereby greatly consuming manpower and increasing labor costs. At the same time, this maintenance method also greatly reduces the maintenance efficiency of the staff and is very inconvenient to operate.

[0006] To achieve the above object, the present invention provides the following technical solution: a detection method for a gas fire extinguishing system of a building fire protection facility, comprising the following implementation steps:

[0007] S1: Regular maintenance, by setting a timer at the location of the building where the gas fire extinguishing system is installed, and setting the timer to start once every 1-3 months, and sending a maintenance signal to the staff's mobile phone;

[0008] S2: Sensitivity test. After the staff receives the maintenance signal on their mobile phones and rushes to the scene, they need to adjust the circuit connected to the smoke detector to open the circuit, and then use the detection circuit to form a closed loop with the smoke detector to perform sensitivity test.

[0009] S3: Circuit detection, by connecting the circuits with test lights in parallel to the various circuits in the gas fire extinguishing system, energizing the circuits, and observing whether the test lights are lit to perform circuit breakage test on the circuits;

[0010] S4: Fire extinguishing effect test, by extracting a small amount of gas samples from the gas fire extinguishing agent bottle group, and using a gas detection instrument to test the composition ratio, so as to obtain the theoretical fire extinguishing effect of the gas fire extinguishing agent;

[0011] S5: Pipeline pressure detection, by pre-arranging a pressure detection module and a pressure data display panel in the pipeline for conveying gas fire extinguishing agent, and by comparing the preset pressure of the pipeline, the pipeline pressure detection result is obtained;

[0012] S6: Failure rate detection, record the components and circuits with problems in the gas fire extinguishing system, and summarize the past detection data to obtain the latest failure rate;

[0013] S7: Repair and improvement. After completing the above inspection steps, the parts and circuits that need to be repaired are recorded, and then the staff will carry out repairs with relevant tools.

[0014] Furthermore, the specific steps of sending the maintenance signal in step S1 are as follows:

[0015] S101: After the timer is adjusted to a preset time between 1 and 3 months, a circuit is disconnected between the timer and the positioning module set in the timer;

[0016] S102: When the timer reaches the preset start time, a closed loop is formed between the timer and the positioning module, and the timer and the positioning module can simultaneously send electrical signals to the outside;

[0017] S103: The staff can receive the detection signal and the location signal of the gas fire extinguishing system that needs to be detected through the mobile phone.

[0018] Furthermore, the specific steps of the timer and the positioning module simultaneously sending the electrical signal to the outside in S102 are as follows:

[0019] S1021: a processor with information aggregation is provided in a building area where a gas fire extinguishing system is provided, and the processor is electrically connected to a locator and a positioning module;

[0020] S1022: Setting a signal sending module in a building area where a gas fire extinguishing system is installed, and electrically connecting the signal sending module to a processor;

[0021] S1023: The timer and positioning module will send a signal to the processor. After the processor processes the detection signal and the positioning signal, the signal can be sent to the staff's mobile phone through the signal sending module.

[0022] Furthermore, the specific steps of smoke detector sensitivity detection in S2 are as follows:

[0023] S201: When testing the sensitivity of the smoke detector, it is necessary to first disconnect the smoke detector from the gas fire extinguishing system circuit using a circuit switch;

[0024] S202: The two ends of the detection circuit driven by the light emitting diode, multiple sets of batteries and the circuit switch can be connected to the positive and negative output ends of the smoke detector respectively;

[0025] S203: preparing a combustion container, combustion paper and a lighter, and igniting the combustion paper in the combustion container by using the lighter;

[0026] S204: Place the opening of the combustion container toward the smoke detector, close the circuit switch on the detection circuit, and determine the start sensitivity of the smoke detector by observing whether the light-emitting diode is lit.

[0027] Furthermore, the steps for determining the sensitivity of the smoke detector in S204 are as follows:

[0028] S2041: When the smoke detector detects smoke released by burning paper in the combustion container, a closed circuit is formed inside the smoke detector;

[0029] S2042: A closed loop is formed between the smoke detector and the detection circuit, so that the light-emitting diode is powered on and emits light;

[0030] S2043: On the contrary, when the smoke detector cannot detect the smoke released by the burning paper in the burning container, a closed loop cannot be formed between the detection circuit and the smoke detector, and the light-emitting diode cannot emit light when powered on.

[0031] Furthermore, the specific steps of circuit detection in the gas fire extinguishing system in S3 are as follows:

[0032] S301: Connecting two ends of a detection circuit having a light emitting diode, a plurality of battery groups and a circuit switch to two ends of a circuit to be tested respectively;

[0033] S302: At this time, by turning on the circuit switch, observe whether the light-emitting diode emits light. If it does not emit light, one end of the detection circuit can be removed from the circuit to be tested;

[0034] S303: Afterwards, the lower end of the detection circuit is connected to the middle position of the circuit to be tested, and the circuit switch is turned on to observe whether the light-emitting diode emits light again;

[0035] S304: If it does not emit light, the above steps can be repeated again, and this time the lower end of the detection circuit needs to be connected to the middle of the detection distance at this time;

[0036] S305: Repeat this step according to this rule to find the location of the circuit breaker.

[0037] Furthermore, the specific steps of further refining the circuit break position in S305 are as follows:

[0038] S3051: If the light emitting diode lights up during the detection process, it means that there is no circuit breakage in the circuit segment to be tested between the detection circuits;

[0039] S3052: At this time, it is necessary to separate the two ends of the detection circuit from the circuit to be tested, and connect the other end of the detection circuit to one end of the detection position in the previous step;

[0040] S3053: Connect one end of the detection circuit to one end of the circuit to be tested in the first two steps, so as to continue to repeat the steps of measuring whether the circuit is open and determine the open position.

[0041] Furthermore, the specific steps of fire extinguishing effect detection in S4 are as follows:

[0042] S401: before extracting the gas, the gas fire extinguishing agent bottle group is shaken to mix the gas fire extinguishing agent inside the bottle group;

[0043] S402: Then, the gas fire extinguishing agent in the bottle group is extracted and tested by the gas detection instrument, and the gas fire extinguishing agent is compared with the preset theoretical data after the test;

[0044] S403: When the comparison results are significantly different, the gas fire extinguishing agent bottle group can be moved again, and then the above steps can be repeated;

[0045] S404: The components and proportions of the gaseous fire extinguishing agent are repeatedly detected until the data are close or have a large difference, and finally the data is recorded to complete the fire extinguishing effect detection.

[0046] Furthermore, the specific steps of pipeline pressure detection in S5 are as follows:

[0047] S501: When the staff samples the gas fire extinguishing agent, the pressure in the pipeline for conveying the gas fire extinguishing agent will change due to the delivery and replenishment of the gas;

[0048] S502: By recording the pressure data, it is displayed on the panel whether the data of the gas pressure inside the pipeline before and after sampling are consistent, so as to judge whether the pressure of the gas fire extinguishing agent in the pipeline is normal.

[0049] Furthermore, the specific steps of failure rate detection summary in S6 are as follows:

[0050] S601: After the detected data of each component and circuit are summarized, they are added together with the previous groups of data;

[0051] S602: By adding up the sum of each group of data and arranging them, a permutation table of the maintenance failure rate can be obtained, and the permutation table is uploaded to the processor;

[0052] S603: The processor sends the inspection failure rate and data to the staff's mobile phone through the signal sending module;

[0053] S604: The staff can view the data and focus on checking the components and circuits with high failure rates during the next maintenance work.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. The present invention proposes a detection method for a gas fire extinguishing system of a building fire protection facility. The timer can send an accurate maintenance signal to the staff within a preset time. When the timer sends the maintenance signal to the designated staff's mobile phone through the processor and the signal sending module, the staff can quickly find the corresponding gas fire extinguishing system that needs maintenance through the position of the locator in the gas fire extinguishing system displayed on the mobile phone. This not only allows the staff to quickly obtain the specific location of the gas fire extinguishing system that needs maintenance, without having to check the gas fire extinguishing systems in the entire building one by one, but also greatly improves the maintenance efficiency, reduces labor costs, and saves manpower. After maintenance, by summarizing and uploading various data to the processor, the maintenance failure rate and data are sent to each staff member's mobile phone through the processor, forming special detection data for a gas fire extinguishing system. Not only can the staff conduct special key inspections in the subsequent maintenance process to improve the inspection efficiency, but also when a staff member resigns, the new staff or other staff can quickly hand over and understand the gas fire extinguishing system of one place.

[0056] 2. The present invention proposes a detection method for a gas fire extinguishing system of a building fire protection facility. When a staff member detects the sensitivity of a smoke detector, the smoke detector is disconnected from the entire gas fire extinguishing system circuit so that the activation of the smoke detector will not affect the entire gas fire extinguishing system. Thereafter, the positive and negative electrodes of the detection circuit are respectively connected to the positive and negative electrodes of a single smoke detector. The staff member can activate the smoke detector through a burning container and burning paper carried by the staff member. By providing multiple sets of batteries in the detection circuit, when the smoke detector detects the smoke released by the burning paper in the burning container, it will form a closed loop with the detection circuit. The smoke sensitivity of the smoke detector can be quickly determined by providing electrical energy, the luminous effect of the light-emitting diode, and the size of the released smoke through the multiple sets of batteries. This detection method not only makes it convenient for the staff member to carry the detection circuit with them, but also does not activate other components and circuits in the gas fire extinguishing system when detecting the sensitivity of the smoke detector. The operation is convenient and quick, the detection cost is saved, and the use is convenient.

[0057] 3. The present invention proposes a detection method for a gas fire extinguishing system of a building fire protection facility. When detecting the circuit in the gas fire extinguishing system, the detection circuit for detecting the sensitivity of the smoke detector can be used to implement the detection. During the detection, by adopting a detection method of half the entire detection length, the circuit break position in the circuit can be quickly determined. Then, by separating the two ends of the detection circuit from the circuit to be tested, and connecting the other end of the detection circuit to one end of the detection position of the previous step, and connecting one end of the detection circuit to one end of the circuit to be tested in the first two steps, and then adopting a detection method of half the entire detection length at this time, such reciprocating operation can quickly determine a more precise circuit break position. This arrangement not only improves the detection efficiency of circuit breaks, reduces the cost of replacing circuit break lines, and saves manpower, but also allows the detection circuit to be used in multiple ways, is easy to carry, and saves detection costs.

[0080] The specific steps of sending the maintenance signal in step S1 are as follows:

[0081] S101: After the timer is adjusted to a preset time between 1 and 3 months, a circuit is disconnected between the timer and the positioning module set in the timer;

[0082] S102: When the timer reaches the preset start time, a closed loop is formed between the timer and the positioning module, and the timer and the positioning module can simultaneously send electrical signals to the outside;

[0083] S103: The staff can receive the detection signal and the location signal of the gas fire extinguishing system that needs to be detected through the mobile phone.

[0084] The specific steps of the timer and the positioning module simultaneously sending the electrical signal to the outside in S102 are as follows:

[0086] S1022: Setting a signal sending module in a building area where a gas fire extinguishing system is installed, and electrically connecting the signal sending module to a processor;

[0087] S1023: The timer and positioning module will send a signal to the processor. After the processor processes the detection signal and the positioning signal, the signal can be sent to the staff's mobile phone through the signal sending module.

[0088] The specific steps of failure rate detection summary in S6 are as follows:

[0089] S601: After the detected data of each component and circuit are summarized, they are added together with the previous groups of data;

[0090] S602: By adding up the sum of each group of data and arranging them, a permutation table of the maintenance failure rate can be obtained, and the permutation table is uploaded to the processor;

[0091] S603: The processor sends the inspection failure rate and data to the staff's mobile phone through the signal sending module;

[0092] S604: The staff can view the data and focus on checking the components and circuits with high failure rates during the next maintenance work.

[0093] Specifically, the timer can send accurate maintenance signals to the staff within a preset time. When the timer sends the maintenance signal to the designated staff's mobile phone through the processor and the signal sending module, the staff can quickly find the corresponding gas fire extinguishing system that needs maintenance through the position of the locator in the gas fire extinguishing system displayed on the mobile phone. This not only allows the staff to quickly obtain the specific location of the gas fire extinguishing system that needs maintenance, without having to check the gas fire extinguishing systems in the entire building one by one, but also greatly improves the maintenance efficiency, reduces labor costs, and saves manpower. After maintenance, by summarizing and uploading various data to the processor, the maintenance failure rate and data are sent to each staff member's mobile phone through the processor to form special detection data for a gas fire extinguishing system. This not only allows the staff to conduct special key inspections in the subsequent maintenance process to improve the inspection efficiency, but also when a staff member resigns, new employees or other staff members can quickly hand over and understand the gas fire extinguishing system at one place.

[0094] In order to solve the problem that the overall gas fire extinguishing system is easily activated when the smoke detector is tested for sensitivity, which increases the testing cost, please refer to Figure 2-Figure 6 , provide the following preferred technical solutions:

[0095] The specific steps for smoke detector sensitivity detection in S2 are as follows:

[0096] S201: When testing the sensitivity of the smoke detector, it is necessary to first disconnect the smoke detector from the gas fire extinguishing system circuit using a circuit switch;

[0097] S202: The two ends of the detection circuit driven by the light emitting diode, multiple sets of batteries and the circuit switch can be connected to the positive and negative output ends of the smoke detector respectively;

[0098] S203: preparing a combustion container, combustion paper and a lighter, and igniting the combustion paper in the combustion container by using the lighter;

[0099] S204: Place the opening of the combustion container toward the smoke detector, close the circuit switch on the detection circuit, and determine the start sensitivity of the smoke detector by observing whether the light-emitting diode is lit.

[0100] The steps for determining the sensitivity of the smoke detector in S204 are as follows:

[0101] S2041: When the smoke detector detects smoke released by burning paper in the combustion container, a closed circuit is formed inside the smoke detector;

[0102] S2042: A closed loop is formed between the smoke detector and the detection circuit, so that the light-emitting diode is powered on and emits light;

[0103] S2043: On the contrary, when the smoke detector cannot detect the smoke released by the burning paper in the burning container, a closed loop cannot be formed between the detection circuit and the smoke detector, and the light-emitting diode cannot emit light when powered on.

[0104] Specifically, when the staff is testing the sensitivity of the smoke detector, the smoke detector is disconnected from the entire gas fire extinguishing system circuit so that the activation of the smoke detector will not affect the entire gas fire extinguishing system.
