Description

Technical Field

[0001] This application relates to the field of power grid technology, and in particular to a method, apparatus, equipment, system and medium for detecting and alarming sulfur hexafluoride cylinders. Background Technology

[0002] Sulfur hexafluoride (SF6) gas possesses excellent insulation properties and good arc-quenching performance, making it a widely used insulating gas in the power industry. It is primarily used in electrical equipment such as gas-insulated metal-enclosed switches and gas-insulated enclosed circuits. Its molecular weight is five times that of air, and its ions travel at a much lower speed in an electric field than nitrogen and oxygen plasma in air, thus making recombination more likely and resulting in stronger insulation and arc-quenching capabilities. SF6 gas has high insulation strength, its arc-quenching ability is 100 times that of air, and it also has good heat dissipation capabilities, posing no fire or explosion hazard.

[0003] In the existing technology, after sulfur hexafluoride cylinders are stored in the warehouse, in order to determine whether the sulfur hexafluoride in the cylinders can continue to be used, the staff will conduct regular inspections on the cylinders and manually alarm when the sulfur hexafluoride is detected to be unusable.

[0004] In summary, the existing detection and alarm methods for sulfur hexafluoride cylinders rely on manual inspection and alarm operation by staff, resulting in low detection and alarm efficiency. Summary of the Invention

[0035] The processing module is used to determine whether the sulfur hexafluoride in each sulfur hexafluoride cylinder marked with an entry identifier in the warehouse database is usable based on the detection data of the sulfur hexafluoride cylinder corresponding to the sulfur hexafluoride cylinder identifier.

[0036] The alarm module is used to issue an alarm if it is determined that sulfur hexafluoride in the sulfur hexafluoride cylinder is unavailable.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0060] With the continuous development of the power industry, sulfur hexafluoride (SF6) gas, as an important insulating medium in the power sector, has attracted much attention. SF6 gas possesses excellent high insulation and good arc-quenching properties, making it a widely used insulating gas in the power industry, primarily applied to gas-insulated metal-enclosed switches, gas-insulated enclosed insulated circuits, and other electrical equipment. Its molecular weight is five times that of air, and its ions travel at a much lower speed in an electric field than nitrogen and oxygen plasma in air, thus making recombination more likely and resulting in stronger insulation and arc-quenching capabilities. SF6 gas has high insulation strength, its arc-quenching ability is 100 times that of air, and it also has good heat dissipation capabilities, posing no fire or explosion hazard.

[0061] In existing technology, after sulfur hexafluoride (SF6) cylinders are stored in a warehouse, staff periodically inspect the cylinders to determine whether the SF6 in the cylinders can still be used. A manual alarm is triggered when the SF6 is found to be unusable. However, due to the large number of SF6 cylinders in the warehouse, the detection and alarm efficiency is low, and there are also issues with untimely alarms.

[0062] To address the problems existing in the prior art, the inventors, during their research on sulfur hexafluoride (SF6) cylinder detection and alarm methods, discovered that to improve detection and alarm efficiency, sensors can be used to collect data from SF6 cylinders in the warehouse, storing this data as SF6 cylinder detection data in a warehouse database. Real-time detection is then performed, retrieving the SF6 cylinder detection data corresponding to the cylinder's identification from the warehouse database. Based on this data, the usability of the SF6 in the cylinder is determined, and an alarm is triggered when SF6 is deemed unusable. Based on this inventive concept, the SF6 cylinder detection and alarm scheme of this application was designed.

[0063] The execution entity of the sulfur hexafluoride cylinder detection and alarm method in this application can be a server, a computer, a terminal device, etc. This application does not limit it. The following explanation uses a server as an example.

[0064] For example, Figure 1 This is a schematic diagram of the sulfur hexafluoride cylinder detection alarm scenario provided in this application, such as... Figure 1 As shown, this application scenario may include server 11, warehouse 14, multiple sulfur hexafluoride cylinders and multiple exhaust fans.

[0065] In this application scenario, taking sulfur hexafluoride cylinder 12 as an example, sulfur hexafluoride cylinder 12 is equipped with an identification tag. An inbound reading device is set up in warehouse 14. When sulfur hexafluoride cylinder 12 is put into the warehouse, the inbound reading device will scan the identification tag on sulfur hexafluoride cylinder 12, and then determine the sulfur hexafluoride cylinder identifier of sulfur hexafluoride cylinder 12 and send it to server 11.

[0066] It should be noted that the identification tag can be a Radio Frequency Identification (RFID) tag, a QR code, a barcode, etc. The inbound reading device can be an RFID reader / writer, a terminal with a camera, a barcode scanner, etc. This application does not limit the identification tag and the inbound reading device; they can be determined according to the actual situation.

[0067] Server 11 stores the sulfur hexafluoride cylinder identification mark into the warehouse database, and then constructs the sulfur hexafluoride cylinder detection data corresponding to the sulfur hexafluoride cylinder identification mark in the warehouse database.

[0068] A pressure sensor, a moisture sensor, and a temperature sensor are installed on the gas cylinder, and a weight sensor is located at the bottom of the cylinder. The pressure sensor collects the cylinder pressure and sends the collected pressure along with the sulfur hexafluoride cylinder identification to server 11. The moisture sensor collects the amount of moisture in the cylinder and sends the amount of moisture along with the sulfur hexafluoride cylinder identification to server 11. The temperature sensor collects the cylinder temperature and sends the temperature along with the sulfur hexafluoride cylinder identification to server 11. The weight sensor collects the cylinder weight and sends the weight along with the sulfur hexafluoride cylinder identification to server 11.

[0069] Server 11 will update the sulfur hexafluoride cylinder detection data corresponding to the target sulfur hexafluoride cylinder identifier in the warehouse database. The target sulfur hexafluoride cylinder identifier is the sulfur hexafluoride cylinder identifier sent by the sensor.

[0070] Server 11 can perform real-time monitoring and retrieve the sulfur hexafluoride (SF6) cylinder detection data corresponding to the SF6 cylinders marked with the warehousing identification from the warehouse database. Based on this data, it determines whether the SF6 in cylinder 12 is usable; if it is determined that the SF6 in cylinder 12 is unusable, an alarm is triggered.

[0071] Server 11 can also obtain the sulfur hexafluoride content in warehouse 14. If it is determined that the sulfur hexafluoride content is greater than the preset content threshold, it controls all exhaust fans (including exhaust fan 13) in warehouse 14 to turn on and issue an alarm.

[0072] It should be noted that the preset content threshold can be 800ppm, 1000ppm, 1200ppm, etc. This application embodiment does not limit the preset content threshold, which can be determined according to the actual situation.

[0073] An outbound reading device is set up in warehouse 14. When sulfur hexafluoride cylinder 12 is taken out of the warehouse, the outbound reading device will scan the identification tag on the sulfur hexafluoride cylinder 12, and then determine the sulfur hexafluoride cylinder identification of the sulfur hexafluoride cylinder 12 and send it to the server 11.

[0074] It should be noted that the outbound reading device can be an RFID reader, a terminal with a camera, a barcode scanner, etc. This application does not limit the outbound reading device; it can be determined according to the actual situation.

[0075] Server 11 replaces the inbound identifier of the sulfur hexafluoride cylinder in the warehouse database with the outbound identifier.

[0076] It should be noted that, Figure 1 This is merely a schematic diagram illustrating one application scenario provided by an embodiment of this application. This embodiment does not necessarily represent... Figure 1The document does not limit the actual form of the various devices included, nor does it specify the form of the devices. Figure 1 The interaction methods between devices are limited, and can be set according to actual needs in the specific application of the solution.

[0077] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0078] Figure 2 This is a flowchart illustrating an embodiment of the sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this application. This embodiment describes how the server responds to SF6 cylinder detection alarms based on SF6 cylinder detection data. The method in this embodiment can be implemented through software, hardware, or a combination of both.

[0079] The warehouse database stores sulfur hexafluoride (SF6) cylinder identifiers marked with an inbound identifier and / or an outbound identifier. An inbound identifier indicates that the corresponding SF6 cylinder is in the warehouse. An outbound identifier indicates that the corresponding SF6 cylinder is not in the warehouse.

[0080] It should be noted that the inbound and outbound identifiers can be numbers, letters, Chinese characters, etc. This application embodiment does not limit the inbound and outbound identifiers, and they can be determined according to the actual situation.

[0081] Since only the sulfur hexafluoride cylinders in the warehouse need to be tested, therefore... Figure 2 As shown, the following steps are performed on each sulfur hexafluoride cylinder identifier marked with an entry identifier in the warehouse database:

[0082] S201: Retrieve the sulfur hexafluoride cylinder inspection data corresponding to the sulfur hexafluoride cylinder identification from the warehouse database.

[0083] In this step, in order to detect the sulfur hexafluoride cylinder, it is necessary to obtain the sulfur hexafluoride cylinder detection data corresponding to the cylinder's identification from the warehouse database.

[0084] The sulfur hexafluoride cylinder test data includes cylinder weight, cylinder pressure, cylinder moisture content, and cylinder temperature.

[0085] For example, Table 1 is a data table of sulfur hexafluoride cylinder test data provided in this application.

[0086] Table 1

[0087]

[0088] As shown in Table 1, the sulfur hexafluoride (SF6) cylinder marked 0003 weighs 70 kg, has a pressure of 2 MPa, a moisture content of 30 ppm, and a temperature of 16 degrees Celsius. This application does not limit the marking or testing data of the SF6 cylinder; these can be determined based on actual conditions.

[0089] S202: Determine whether the sulfur hexafluoride in the sulfur hexafluoride cylinder is usable based on the test data of the sulfur hexafluoride cylinder.

[0090] In this step, after the server obtains the sulfur hexafluoride cylinder detection data, it determines whether the sulfur hexafluoride in the cylinder is usable based on the sulfur hexafluoride cylinder detection data.

[0091] Specifically, based on the test data of the sulfur hexafluoride cylinder, if at least one of the first, second, third, and fourth preset conditions is determined to be met, then the sulfur hexafluoride in the sulfur hexafluoride cylinder is determined to be unusable.

[0092] Based on the test data of the sulfur hexafluoride cylinder, if it is determined that the first, second, third, and fourth preset conditions are all not met, then it is determined that the sulfur hexafluoride in the sulfur hexafluoride cylinder is usable.

[0093] The first preset condition is that the weight of the gas cylinder is less than a preset weight threshold; the second preset condition is that the pressure of the gas cylinder is less than a preset pressure threshold; the third preset condition is that the amount of water in the gas cylinder is greater than a preset amount of water threshold; and the fourth preset condition is that the temperature of the gas cylinder is less than a preset temperature threshold.

[0094] It should be noted that the preset weight threshold can be 60kg, 65kg, 70kg, etc., the preset pressure threshold can be 0.03MPa, 0.04MPa, 0.05MPa, etc., the preset trace moisture threshold can be 80ppm, 100ppm, 120ppm, etc., and the preset temperature threshold can be -0.5 degrees Celsius, 0 degrees Celsius, 0.5 degrees Celsius, etc. This application does not limit the preset weight threshold, preset pressure threshold, preset trace moisture threshold, and preset temperature threshold; they can be determined according to actual conditions.

[0095] S203: If it is determined that the sulfur hexafluoride in the sulfur hexafluoride cylinder is unusable, an alarm will be issued.

[0096] In this step, if the server determines that the sulfur hexafluoride in the sulfur hexafluoride cylinder is unavailable, it will issue an alarm.

[0097] Specifically, the conditions that are met among the first, second, third, and fourth preset conditions are determined, and the alarm segments corresponding to the met conditions are combined to generate alarm information. The alarm information is then output. If each sulfur hexafluoride cylinder in the warehouse is also equipped with an audible and visual alarm device, the audible and visual alarm device corresponding to the sulfur hexafluoride cylinder identifier will emit a light of a color used to indicate that sulfur hexafluoride is unavailable, such as red, and play the alarm information.

[0098] For example, the alarm message corresponding to the first preset condition is: Air cylinder, not usable. The alarm message corresponding to the second preset condition is: Low air pressure, not usable. The alarm message corresponding to the third preset condition is: Excessive moisture content, not usable. The alarm message corresponding to the fourth preset condition is: Abnormal temperature, not usable.

[0099] It should be noted that the system can also output the sulfur hexafluoride (SF6) cylinder detection data corresponding to the SF6 cylinder identification. The output of alarm information and SF6 cylinder detection data can be achieved in several ways: sending alarm information and SF6 cylinder detection data to the operator's terminal device; displaying alarm information and SF6 cylinder detection data on a screen; or playing alarm information and SF6 cylinder detection data through a speaker.

[0100] It should be noted that the sulfur hexafluoride (SF6) cylinder detection data also includes the time of entry into storage. Starting from the time of entry, the server outputs a message prompting manual inspection at regular intervals. This message includes the SF6 cylinder's identifier, instructing staff to manually inspect the gas inside the cylinder for contamination and determine if the SF6 can continue to be used.

[0101] The method for outputting the message indicating that manual inspection is required can be: sending the message to the worker's terminal device; displaying the message on a screen; or having the audible and visual alarm device of the sulfur hexafluoride cylinder corresponding to the cylinder's identification emit a light of a color indicating the need for manual inspection, such as yellow, and play the message.

[0102] The interval reminder period can be 3 months, 6 months, 9 months, etc. This application embodiment does not limit the interval reminder period, which can be determined according to the actual situation.

[0103] It should be noted that if it is determined that the sulfur hexafluoride in the sulfur hexafluoride cylinder is usable, an audible and visual alarm device can be used to emit light, such as a green light, to indicate that the sulfur hexafluoride is available.

[0104] It should be noted that staff can also use terminal devices to send test data query requests to the server. These requests include the identification of the sulfur hexafluoride (SF6) cylinder to be queried. Based on the SF6 cylinder identification, the server retrieves the corresponding SF6 cylinder test data from the warehouse database and sends it to the terminal device for staff to view.

[0105] The sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this embodiment obtains the SF6 cylinder detection data corresponding to the SF6 cylinders marked with entry identification from the warehouse database. Based on the cylinder weight, cylinder pressure, cylinder moisture content, and cylinder temperature in the SF6 cylinder detection data, it determines whether the SF6 in the cylinder is usable. If the SF6 in the cylinder is determined to be unusable, an alarm is triggered. This solution performs detection and alarm based on the obtained SF6 cylinder detection data, eliminating the need for manual detection and alarming, thus improving detection and alarm efficiency. Detection using multiple data sources improves detection accuracy.

[0106] Figure 3 This is a flowchart illustrating Embodiment Two of the sulfur hexafluoride cylinder detection and alarm method provided in this application. Based on the above embodiments, this application embodiment describes the situation where a server detects whether the sulfur hexafluoride content in a warehouse is abnormal. Figure 3 As shown, the specific steps of the sulfur hexafluoride cylinder detection and alarm method include:

[0107] S301: Obtain the sulfur hexafluoride content in the warehouse.

[0108] To detect whether sulfur hexafluoride cylinders are leaking, gas sensors are installed in the warehouse. The gas sensors send the real-time sulfur hexafluoride content to the server.

[0109] In this step, to determine whether the sulfur hexafluoride cylinder is leaking, it is necessary to obtain the sulfur hexafluoride content in the warehouse.

[0110] S302: If the sulfur hexafluoride content is greater than the preset content threshold, the exhaust fan will be turned on and an alarm will be triggered.

[0111] In this step, after the server obtains the sulfur hexafluoride content, if it determines that the sulfur hexafluoride content is greater than the preset content threshold, it indicates that the sulfur hexafluoride cylinder is leaking. In order to reduce the hazards of sulfur hexafluoride and improve warehouse safety, since the warehouse is equipped with exhaust fans, the exhaust fans are turned on and an alarm is triggered.

[0112] It should be noted that the preset content threshold can be 800ppm, 1000ppm, 1500ppm, etc. This application embodiment does not limit the preset content threshold, which can be determined according to the actual situation.

[0113] It should be noted that the alarm can be triggered in several ways: First, by sending a sulfur hexafluoride (SF6) cylinder leak warning message to the staff's terminal device. Second, by displaying the SF6 cylinder leak warning message on a screen. Third, by transmitting the SF6 cylinder leak warning message via loudspeaker.

[0114] For example, Figure 4 This is a schematic diagram illustrating a scenario where the exhaust fan is turned on, as provided in this application. Figure 4 As shown, the gas sensor sends the collected sulfur hexafluoride (SF6) content to the server. When the server determines that the SF6 content exceeds a preset threshold, it sends a command to the controller to turn on the exhaust fan. The controller is connected to the exhaust fan and can control the exhaust fan to turn on according to the command.

[0115] The sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this embodiment improves warehouse safety by controlling the exhaust fan to start and triggering an alarm when the SF6 content exceeds a preset threshold. The alarm also alerts staff to promptly handle any leaking SF6 cylinders, reducing other waste of SF6 and mitigating environmental impact.

[0116] Figure 5 This is a flowchart illustrating Embodiment 3 of the sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this application. Based on the above embodiments, this application embodiment describes the generation of SF6 cylinder detection data by the server when SF6 cylinders are put into storage. Figure 5 As shown, the specific steps of the sulfur hexafluoride cylinder detection and alarm method include:

[0117] S501: Receives the sulfur hexafluoride cylinder identification sent by the warehouse entry reading device.

[0118] Sulfur hexafluoride (SF6) cylinders are equipped with identification tags. When SF6 cylinders are stored in the warehouse, the identification tags are scanned by the identification tags to determine the SF6 cylinder's identity and then the information is sent to the server.

[0119] In this step, after the warehousing and reading device identifies the sulfur hexafluoride cylinder and sends it to the server, the server can receive the sulfur hexafluoride cylinder identification.

[0120] S502: Mark the sulfur hexafluoride cylinders with the warehouse entry label.

[0121] In this step, after the server receives the sulfur hexafluoride cylinder identifier, since the identifier was sent by the warehouse entry reading device, it needs to be processed for warehouse entry, and the sulfur hexafluoride cylinder identifier needs to be marked with a warehouse entry identifier.

[0122] S503: Store the sulfur hexafluoride cylinder label after it has been marked as being stored in the warehouse database.

[0123] S504: Construct sulfur hexafluoride (SF6) cylinder detection data corresponding to the SF6 cylinder identification in the warehouse database.

[0124] In the above steps, after the server marks the sulfur hexafluoride cylinder with the warehouse entry mark, in order to carry out subsequent testing, the marked sulfur hexafluoride cylinder mark needs to be stored in the warehouse database, and then the sulfur hexafluoride cylinder testing data corresponding to the sulfur hexafluoride cylinder mark needs to be constructed in the warehouse database.

[0125] It should be noted that there are empty data in the sulfur hexafluoride cylinder test data at this time.

[0126] For example, Table 2 is a data table two of the sulfur hexafluoride cylinder test data provided in this application.

[0127] Table 2

[0128]

[0129] As shown in Table 2, the sulfur hexafluoride cylinder is marked as 0002, and the cylinder weight, cylinder pressure, cylinder moisture content, and cylinder temperature are all empty data.

[0130] In one implementation, after the server receives the sulfur hexafluoride (SF6) cylinder identifier from the inbound reading device, if the identifier is already stored in the warehouse database and is marked as an outbound identifier, the outbound identifier is replaced with an inbound identifier, and the SF6 cylinder detection data is updated to empty data. If the identifier is marked as an inbound identifier, a duplicate inbound notification message is output, including the SF6 cylinder identifier, for staff to check.

[0131] It should be noted that the server can also store the moment when it receives the sulfur hexafluoride cylinder identifier sent by the warehousing and reading device as the warehousing moment in the sulfur hexafluoride cylinder detection data.

[0132] S505: Receives sensor data and sulfur hexafluoride cylinder identification sent by the sensor.

[0133] After sulfur hexafluoride (SF6) cylinders are stored, pressure sensors, moisture sensors, and temperature sensors are installed on them, and a weight sensor is installed at the bottom of the cylinder. The pressure sensor collects the cylinder pressure and sends the collected pressure along with the SF6 cylinder identification to the server. The moisture sensor collects the amount of moisture in the cylinder and sends the moisture amount along with the SF6 cylinder identification to the server. The temperature sensor collects the cylinder temperature and sends the temperature along with the SF6 cylinder identification to the server. The weight sensor collects the cylinder weight and sends the weight along with the SF6 cylinder identification to the server.

[0134] In this step, after the pressure sensor, micro-moisture sensor, temperature sensor, or weight sensor sends sensor data and sulfur hexafluoride cylinder identification to the server, the server can receive the sensor data and sulfur hexafluoride cylinder identification sent by the sensor. The sensor data includes cylinder weight, cylinder pressure, cylinder micro-moisture content, or cylinder temperature.

[0135] S506: Update the detection data of sulfur hexafluoride cylinders corresponding to the target sulfur hexafluoride cylinder identifier in the warehouse database based on sensor data.

[0136] In this step, after the server receives the sensor data and sulfur hexafluoride cylinder identifier sent by the sensor, it updates the sulfur hexafluoride cylinder detection data corresponding to the target sulfur hexafluoride cylinder identifier in the warehouse database based on the sensor data. The target sulfur hexafluoride cylinder identifier is the sulfur hexafluoride cylinder identifier sent by the sensor.

[0137] For example, based on Table 2, Table 3 is a data table of sulfur hexafluoride cylinder test data provided in this application.

[0138] Table 3

[0139]

[0140] As shown in Table 3, the weight sensor sends the sulfur hexafluoride cylinder identifier 0002 and the cylinder weight 80 to the server. The server finds the corresponding sulfur hexafluoride cylinder detection data based on 0002. Since the cylinder weight is empty in the sulfur hexafluoride cylinder detection data, 80 is filled in the sulfur hexafluoride cylinder detection data.

[0141] For example, based on Table 1, Table 4 is a data table four of the sulfur hexafluoride cylinder test data provided in this application.

[0142] Table 4

[0143]

[0144] As shown in Table 4, the weight sensor sends the sulfur hexafluoride cylinder identifier 0003 and the cylinder moisture level 50 to the server. The server finds the corresponding sulfur hexafluoride cylinder detection data based on 0003. Since the cylinder moisture level in the sulfur hexafluoride cylinder detection data is 30, which is not a null value, 30 is replaced with 50.

[0145] The sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this embodiment achieves SF6 cylinder warehousing management by marking the cylinders with warehousing identification tags and storing them in a warehouse database. This eliminates the need for manual warehousing management, improving efficiency and accuracy. Furthermore, by updating the SF6 cylinder detection data using sensor data, real-time updates of the SF6 cylinder detection data are achieved, eliminating the need for manual recording and further improving efficiency. This also provides a basis for SF6 cylinder detection.

[0146] Figure 6 This is a flowchart illustrating Embodiment 4 of the sulfur hexafluoride cylinder detection and alarm method provided in this application. Based on the above embodiments, this embodiment describes the situation where the server replaces the warehouse entry identifier with the warehouse exit identifier when the sulfur hexafluoride cylinder leaves the warehouse. Figure 6 As shown, the specific steps of the sulfur hexafluoride cylinder detection and alarm method include:

[0147] S601: Receives the sulfur hexafluoride cylinder identifier sent by the outbound reading device.

[0148] Sulfur hexafluoride (SF6) cylinders are equipped with identification tags. Outbound reading devices are installed in the warehouse. When an SF6 cylinder leaves the warehouse, the outbound reading device scans the identification tag on the SF6 cylinder, thereby identifying the SF6 cylinder's identifier and sending it to the server.

[0149] In this step, after the outbound reading device identifies the sulfur hexafluoride cylinder and sends it to the server, the server can receive the sulfur hexafluoride cylinder identification.

[0150] S602: Replace the inbound identifier of the sulfur hexafluoride cylinder in the warehouse database with the outbound identifier.

[0151] In this step, after the server receives the sulfur hexafluoride cylinder identifier, since the identifier was sent by the outbound reading device, it needs to be processed for outbound. In order to avoid subsequent detection of the sulfur hexafluoride cylinder corresponding to the identifier, the inbound identifier of the sulfur hexafluoride cylinder in the warehouse database needs to be replaced with the outbound identifier.

[0152] It should be noted that the server can also store the time when it receives the sulfur hexafluoride cylinder identifier sent by the outbound reading device as the outbound time in the sulfur hexafluoride cylinder detection data.

[0153] The sulfur hexafluoride (SF6) cylinder detection and alarm method provided in this embodiment replaces the warehousing identification mark of the SF6 cylinder with the exit identification mark, thereby realizing the outbound management of SF6 cylinders without the need for manual outbound management, improving efficiency and accuracy, and also ensuring that no detection and alarm are triggered for outbound SF6 cylinders.

[0160] In one implementation, the sulfur hexafluoride (SF6) cylinder detection and alarm system 700 further includes a gas sensor, a controller, and an exhaust fan. The gas sensor sends the collected SF6 content data to a server. When the server determines that the SF6 content exceeds a preset threshold, it sends a command to the controller to activate the exhaust fan. The controller is connected to the exhaust fan and can control the exhaust fan to activate according to the command.

[0161] It should be noted that sensors such as pressure sensors, micro-moisture sensors, temperature sensors, weight sensors, and gas sensors can interact directly with the server or through relay devices. The interaction method can be via Long Range Radio (LoRa), Bluetooth, wired networks, etc. This application does not limit the interaction method between the sensors and the server; it can be determined according to the actual situation.
