All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 2 is a flowchart of another emergency duration determination method provided in the embodiment of the present application, and referring to fig. 2, the method includes the following steps.
Step 201: the terminal determines the total pipe stock of the pipeline of the target gas supply area and the residual pipe stock of the pipeline corresponding to the lowest gas supply pressure of the target gas supply area, and the target gas supply area is the gas supply area in an accident state.
Since a pipeline for transporting natural gas may leak due to various problems during transportation of natural gas, it is impossible to transport natural gas. The sub-area for which the faulty pipeline is responsible may not receive the natural gas supply, and in order to enable the sub-area for which the faulty pipeline is responsible to receive the natural gas supply, the terminal may control non-faulty pipelines other than the faulty pipeline in the target gas supply area to perform emergency supply on the sub-area for which the faulty pipeline is responsible. Since the supply sub-area exists in the other non-faulty pipelines themselves and the sub-area for which the faulty pipeline is responsible cannot be supplied for a long time, it is generally necessary to determine the total pipe stock of the target gas supply area and the remaining pipe stock of the pipeline corresponding to the lowest gas supply pressure of the target gas supply area in order to determine the emergency time for emergency supply of the sub-area for which the faulty pipeline is responsible.
It should be noted that the gas supply area in the accident state may include an area where a pipeline in the gas supply area fails, or an area where any pipeline in the gas supply area is shut down and maintained.
As an example, before the terminal determines the total pipe stock of the target gas supply area and the remaining pipe stock of the pipe corresponding to the lowest gas supply pressure of the target gas supply area, the terminal may further obtain historical operation data of the target gas supply area, which may include gas supply pressures of the respective gas supply areas at different periods, corresponding relationships between the gas supply pressures and the pipe stocks before, the gas consumption of the user, and the like.
Since the historical operating data may include the supply air pressures of the respective supply air zones at different times and the correspondence of the supply air pressure to the pipe stock before, as an example, the operation of the terminal to determine the remaining pipe stock of the pipe corresponding to the lowest supply air pressure of the target supply air zone may be: determining a minimum air supply pressure of a target air supply area from historical operating data; and acquiring the corresponding residual pipe stock of the pipeline from the corresponding relation between the gas supply pressure and the pipe stock based on the lowest gas supply pressure.
Because the natural gas pipe network coverage is wider, in order to manage the natural gas pipe network, the terminal can divide the natural gas pipe network into a plurality of gas supply areas. That is, before determining the total pipe stock of the target gas supply area and the remaining pipe stock of the pipe corresponding to the lowest gas supply pressure of the target gas supply area, the terminal may further divide the natural gas pipe network into a plurality of gas supply areas.
As an example, the operation of the terminal to divide the natural gas pipeline network into a plurality of areas may be: acquiring distribution information of pipelines in a natural gas pipeline network, gas source information and/or distribution information of gas inlet and outlet points; based on the distribution information of the pipeline, the gas source information and/or the distribution information of the gas inlet and outlet points, the natural gas pipe network is divided into a plurality of gas supply areas, and the plurality of gas supply areas comprise target gas supply areas.
It should be noted that the air source information may include the type of air source, supplier, and the like.
As an example, the terminal performs area division on the natural gas pipe network based on distribution information of pipelines, gas source information, and/or distribution information of gas inlet and outlet points, and the operation of obtaining a plurality of gas supply areas may be: analyzing the air source of the air inlet point, and determining the type of the air source of the air inlet point; and based on the type of the gas source of the gas inlet point, dividing the natural gas pipe network into a plurality of gas supply areas according to the area division rule.
It should be noted that the area division rule is a rule for specifying an area division method, and the area division rule may include division according to the gas source supply alone, or division according to 2 types or more than 2 types of gas source supply, and/or division according to the same distribution orientation of the gas inlet and outlet points, and/or division according to the same distribution orientation of the pipelines, and so on.
For example, when the natural gas pipeline network includes 33 gas inlet points, and the gas source types of the 33 gas inlet points include 6 types, the dividing operation according to the region division rule may be, based on the gas source types of the gas inlet points: the natural gas pipe network is divided according to independent supply of 6 types of gas sources, or according to combined supply of 2 types or more than 2 types of gas sources, and the natural gas pipe network can be divided into 4 gas supply areas.
It should be noted that, the terminal performs area division on the natural gas pipe network based on the distribution information of the pipelines, the gas source information, and/or the distribution information of the gas inlet and outlet points, and the operation of obtaining a plurality of gas supply areas may include not only the above manner, but also other manners, for example, the terminal may determine the distribution position of the pipelines in the city, and divide the pipelines with the same distribution position in the city into one area according to the area division rule, so as to divide the natural gas pipe network into a plurality of gas supply areas. For example, the pipelines distributed in the east of the city are divided into one area, the pipelines distributed in the south of the city are divided into one area, the pipelines distributed in the west of the city are divided into one area, and the pipelines distributed in the north of the city are divided into one area, so that 4 gas supply areas are obtained.
Step 202: and the terminal determines the emergency pipe stock of the target gas supply area based on the main pipe stock and the residual pipe stock of the target gas supply area.
As an example, the terminal may subtract the remaining pipe inventory from the main pipe inventory of the target gas supply area to obtain the emergency pipe inventory of the target gas supply area.
When a pipeline transports natural gas, not all natural gas can be fully utilized due to the gas supply pressure and the like. When a user cannot use the natural gas without a failure of the pipeline, the natural gas is not present in the pipeline, but the natural gas is less in stock, so that the gas supply pressure is insufficient, and the residual natural gas in the pipeline cannot be provided for the user. Therefore, the terminal needs to remove the unusable natural gas inventory when determining the emergency inventory.
In some embodiments, the method for determining the emergency pipe stock of the target gas supply area by the terminal based on the total pipe stock and the remaining pipe stock of the target gas supply area may include not only the above method, but also other methods, for example, the terminal may subtract the historical lowest gas supply pressure from the current gas supply pressure of the target gas supply area to obtain a pressure difference value; acquiring a corresponding pipe storage amount from a corresponding relation between the pressure and the pipe storage amount based on the pressure difference value; and determining the obtained pipe inventory as the emergency pipe inventory of the target gas supply area.
Step 203: and the terminal determines the emergency time for carrying out emergency gas supply on the target gas supply area based on the emergency pipe stock.
It should be noted that the emergency duration of emergency air supply to the target air supply area may be understood as the duration of emergency repair of a faulty pipeline.
Due to the fact that the pipe stock of other non-fault pipelines is limited and emergency supply cannot be conducted for a long time, if emergency repair cannot be conducted on the fault pipeline in time, when the emergency supply of the other non-fault pipelines is stopped, natural gas cannot be used in the sub-area corresponding to the fault pipeline, and therefore the natural gas using effect is brought to users. Therefore, in order not to affect the use of natural gas by the user, the terminal can determine the emergency duration for emergency gas supply to the target gas supply area based on the emergency pipe stock.
As an example, the terminal may determine the emergency duration for emergency gas supply to the target gas supply area based on the emergency management inventory by: determining the current gas consumption of a target gas supply area; and dividing the emergency pipe stock by the current gas consumption of the target gas supply area to obtain the emergency duration.
It should be noted that the current gas usage amount of the target gas supply area may be obtained according to the gas usage amount of the user obtained by the terminal. As an example, the terminal may add the user gas usage amounts of the respective users of the target gas supply area in the historical operating data for the time period to obtain the current gas usage amount of the target gas supply area.
In some embodiments, the terminal may determine the emergency duration in the above manner, and may also determine the emergency duration according to other manners, for example, the terminal may control other non-faulty pipelines in the target gas supply area to prohibit emergency gas supply for a user whose gas usage is greater than a preset gas usage, determine a current gas usage of the user whose gas usage is less than or equal to the preset gas usage in a current time period, where the current gas usage is the current gas usage of the target gas supply area, and divide the emergency pipe inventory by the current gas usage of the target gas supply area to obtain the emergency duration.
Step 204: and the terminal prompts the emergency duration through the prompt message.
Because the emergency repair of the pipeline is usually manual emergency repair, after the emergency duration is determined at the terminal, in order to enable emergency repair personnel to know the emergency repair time limit of the fault pipeline, the terminal can prompt the emergency duration through prompt information.
As an example, the terminal may prompt the emergency duration by playing the prompt message in voice and/or displaying the prompt message in voice.
