Description

Technical Field

[0001] The present application relates to the technical field of gas pipeline monitoring, and in particular to an operating method for monitoring the private connection and modification of a gas pipeline. Background Art

[0002] As the living environment of old communities in urban villages gradually improves, landlords often transform self-built houses into living apartments or small hotels in order to increase rental income. At the same time, due to the short operating cycle and frequent changes in business formats, the shops in urban villages also need to be frequently renovated. These renovation activities often involve the dismantling and modification of gas pipelines, but some renovation and construction units lack safety awareness in order to save costs and simplify processes. They fail to declare gas outages in accordance with regulations and privately dismantle and modify gas pipelines, which seriously threatens public safety.

[0003] For example, during the renovation of a shop, the abandoned gas pipeline was dismantled privately due to misjudgment of its status, resulting in a gas pipeline leak; during the renovation of a residential building, the construction workers ignored the safety of the gas pipeline and used a grinding machine to cut it without authorization, causing a gas leak.

[0004] However, currently, gas companies lack an effective monitoring method to deal with users who privately dismantle or modify gas pipelines. Usually, they can only determine whether users have privately dismantled or modified gas pipelines through reports from the public and inspections by staff. However, such methods often have a large lag, making it difficult to detect and stop them in time, which seriously affects users' gas safety. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention uses a gas alarm and a user-end gas valve to close the corresponding user-end gas valve and alert the staff when the gas concentration is higher than a preset concentration, overcoming the previous situation where gas leaks had to be discovered only by reports from the public. At the same time, through a low-pressure monitor, abnormal gas supply pressure can be discovered in time, thereby enabling monitoring of whether the gas pipeline has been privately connected or modified.

[0007] The operation method comprises the steps of: using a plurality of the gas alarms to respectively monitor the indoor gas concentration of the corresponding users, and when the gas concentration is higher than a preset concentration, closing the corresponding user-side gas valve and alerting the staff;

[0008] The low-pressure monitor monitors the gas pressure at the end of the building pipeline, and alarms the staff when the gas pressure is lower than the preset pressure. When the gas pressure is lower than the preset pressure for more than a preset time, the building gas valve is closed.

[0009] Furthermore, the early warning device also includes: a CIS information system, and the CIS information system is used to record the gas usage of each user in the building.

[0010] Furthermore, the operation method of the early warning device also includes: recording the gas usage of each user in the building in multiple months through the CIS information system, screening out users whose gas usage in the current month is greater than the gas usage in several months before the current month and the difference is greater than a preset difference, and marking them.

[0027] The invention is further described below by describing embodiments in conjunction with the accompanying drawings.

[0028] This embodiment provides a method for monitoring the unauthorized connection and modification of a gas pipeline. Figures 1 to 3As shown in , in order to solve the above technical problems, the technical solution adopted by the present invention is as follows: applied to an early warning device, the early warning device includes: a plurality of gas alarms 32, a plurality of user-end gas valves 31, a low pressure monitor 22 and a building gas valve 21.

[0029] Specifically, the conventional gas supply pipeline includes: an underground low-pressure courtyard pipe 1, a building gas pipeline 2 and a user gas pipeline 3, which are connected in sequence. Among them, the building gas valve 21 is arranged at the gas supply end of the building gas pipeline 2, and the building gas valve 21 can control the on-off between the underground low-pressure courtyard pipe 1 and the building gas pipeline 2, thereby controlling the gas supply of the building gas pipeline 2. The low-pressure monitor 22 is arranged at the end of the building gas pipeline 2, that is, the low-pressure monitor 22 can monitor the gas pressure at the end of the building gas pipeline 2 farthest from the underground low-pressure courtyard pipe 1. Several user-end gas valves 31 are respectively arranged on the gas supply ends of several user-end gas pipelines, and the user-end gas valves 31 are used to control the on-off between the building gas pipeline 2 and the corresponding user-end gas pipeline, thereby controlling the gas supply of the user-end gas pipeline. Several gas alarms 32 are respectively arranged in the rooms of several users, and the gas alarm 32 is generally selected to be arranged above the user-end gas valve 31, and the gas alarm 32 can monitor the gas concentration in the corresponding user's room.

[0030] The early warning device includes the following operation method: a plurality of gas alarms 32 are used to monitor the indoor gas concentration of the corresponding user, and when the gas concentration is higher than the preset concentration, the corresponding user-side gas valve 31 is closed and an alarm is issued to the staff. Specifically, the preset concentration can be set by the relevant staff, and when the gas concentration is higher than the preset concentration, it can be considered that there is a gas leak in the user-side gas pipeline, which can facilitate the relevant staff to check whether the gas pipeline has been privately connected or modified.

[0031] The air pressure at the end of the building pipeline is monitored by the low-pressure monitor 22, and an alarm is issued to the staff when the air pressure is lower than the preset air pressure. Specifically, in order to ensure the stability and safety of the building gas supply, according to the setting, the terminal operating pressure should be maintained within the range of 2500-3000pa. The preset air pressure can be set by the relevant staff. When the air pressure at the end of the building pipeline is lower than the preset air pressure, it can be considered that the operating pressure of the gas pipeline is abnormal, which usually indicates that the actual gas consumption of the regional building has exceeded the design load, and the regional gas supply pressure needs to be adjusted in time to return to normal. If the pressure further drops below 2500pa or presents a "0" pressure state, it means that the area may be in a gas outage state. At this time, it is necessary to immediately verify whether the legal gas outage approval process has been passed, so as to promptly discover and stop any unauthorized private gas outage behavior, and it is also convenient for relevant staff to check whether the gas pipeline has been privately connected or modified.

[0032] When the air pressure is lower than the preset pressure for more than the preset time, the building gas valve 21 is closed. Preferably, when the air pressure at the end of the building pipeline is lower than the preset pressure, it can be considered that the operating pressure of the gas pipeline is abnormal. If the air pressure at the end of the building pipeline is lower than 2500pa for a long time, in addition to the situation that the actual gas consumption of the regional building has exceeded the design load, it may also be due to the user or the construction unit privately connecting and modifying the gas pipeline, causing the building gas pipeline 2 to leak. If the leakage lasts for a long time, it may cause dangerous situations. Specifically, the preset time can be set by the relevant staff. When the air pressure is lower than the preset pressure for more than the preset time, the building gas valve 21 is closed to avoid dangerous situations caused by long-term leakage of the building gas pipeline 2.

[0033] In one embodiment, the early warning device further includes: a CIS information system, which is used to record the gas usage of each user in the building. The CIS information system, namely the Customer Information System, is a computerized system specially designed to collect, store, manage and analyze customer information. The CIS information system can record the gas usage of each user in the building, and when the gas usage of users in the building is abnormal, it is convenient for relevant staff to discover it.

[0034] In one embodiment, the operation method of the early warning device also includes: recording the gas usage of each user in the building in multiple months through the CIS information system, screening out users whose gas usage in the current month is greater than the gas usage in several months before the current month and marking them. Specifically, the CIS information system can extract the detailed gas usage records of multiple months of multiple buildings in a certain area and the detailed gas usage records of multiple months of each user in the building. Through refined screening, users who have no gas usage records in the current month but have stable gas usage records in the multiple months before the current month can be identified, and it can be preliminarily determined that these users may have abnormal gas usage in the current month. After marking these abnormal users, they will be included in the key monitoring scope, and then the on-site investigation work instructions for the current month can be generated, and a professional team can be organized to conduct on-site verification to confirm the cause of the abnormality, so as to facilitate relevant staff to check whether the gas pipeline has been privately connected or modified.

[0035] In one embodiment, the preset difference is fifty percent of the gas usage of the month.

[0036] In one embodiment, the preset concentration is 0.1% to 1%.

[0037] In one embodiment, the preset air pressure is 2500Pa.

[0038] In one embodiment, the preset time is 30 minutes.

[0039] In one embodiment, the gas alarm 32 is an NB-IoT gas alarm 32. The NB-IoT (Narrowband Internet of Things) gas alarm 32 is a smart device based on narrowband Internet of Things technology, which is specially designed for monitoring gas leaks. This alarm utilizes the low power consumption, wide coverage and high connection density of NB-IoT.

[0040] Specifically, users are at high risk when renovating with gas, such as loose pipe threads, end removal without effective sealing, etc., which may cause gas leakage. The NB-IoT gas alarm 32 can transmit the detected gas leakage information to the gas company, the user's smartphone and the property management system in real time to achieve remote monitoring. Once a gas leak is detected, the NB-IoT gas alarm 32 will immediately sound an alarm and notify the user through a mobile phone application or text message to take timely measures. Preferably, the NB-IoT gas alarm 32 can be linked with other smart home devices or security systems, such as realizing the intelligent operation of automatically closing the user-side gas valve 31, thereby effectively reducing the risk and harm of gas leakage.

[0041] In one embodiment, the early warning device further comprises: an audio-visual early warning publicity device, the audio-visual early warning publicity device comprises: a display, the display is used to play a gas safety publicity video;

[0042] Loudspeaker, the loudspeaker is used to play gas safety publicity audio.

[0043] Specifically, residents’ awareness of gas safety can be raised through text messages, community publicity and other means.

[0044] In summary, the present application relates to the technical field of gas pipeline monitoring, and discloses an operation method for monitoring the private connection and modification of gas pipelines, which includes an early warning device, and the early warning device includes the following operation methods: using a number of gas alarms to monitor the indoor gas concentration of the corresponding users respectively, and when the gas concentration is higher than the preset concentration, the corresponding user-side gas valve is closed and an alarm is given to the staff; the gas pressure at the end of the building pipeline is monitored by a low-pressure monitor, and when the gas pressure is lower than the preset pressure, an alarm is given to the staff; when the gas pressure is lower than the preset pressure for more than a preset time, the building gas valve is closed. The present invention uses a gas alarm and a user-side gas valve to close the corresponding user-side gas valve and to give an alarm to the staff when the gas concentration is higher than the preset concentration, thus overcoming the previous situation of relying on reports from the masses to discover gas leaks; at the same time, through a low-pressure monitor, when the gas supply pressure is abnormal, it can be discovered in time, and it is possible to monitor whether the gas pipeline has been privately connected or modified.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
