Referring to fig. 2, the method includes:
step 201: the terminal obtains first data measured in real time by each pipe section in the natural gas storage and transportation system through the SCADA system.
The natural gas storage and transportation system comprises a plurality of pipe sections, and each pipe section in the plurality of pipe sections is provided with a metering data acquisition instrument; the SCADA system collects the real-time metering data of each pipe section through the metering data collecting instruments arranged on each pipe section, and for convenience of distinguishing, the real-time metering data of each pipe section collected by the SCADA system through the metering data collecting instruments arranged on each pipe section is called as first data; the SCADA transmits the first data of each pipe section to a terminal; the terminal receives the first data of each pipe section transmitted by the SCADA system, so that the first data of each pipe section is acquired. Wherein the first data for each pipe section may be the total amount of natural gas for each pipe network.
Before this step, a user needs to log in the metering management client of the natural gas storage and transportation system through a terminal, and the terminal obtains first data of each pipe section through the SCADA system, so that before the terminal obtains the first data of each pipe section through the SCADA system, it needs to determine whether the user logging in the metering associated client of the natural gas storage and transportation system has a pipe section loss value analysis authority, and if so, step 201 is executed; and if not, prompting the user to analyze the authority of the no-pipe-section loss value.
Wherein, the step of determining whether the user has the authority for analyzing the pipe segment loss value may be:
the terminal sends a query request to a metering management server of the natural gas storage and transportation system through a metering management client of the natural gas storage and transportation system, wherein the query request carries a user identifier of the user; the method comprises the steps that a metering management server of the natural gas storage and transportation system receives a query request sent by a terminal, and determines whether a pipe segment transmission and loss value analysis permission list contains a user identifier, wherein the pipe segment transmission and loss value analysis permission list is used for storing the user identifier with the pipe segment transmission and loss value analysis permission; if the user identification is included in the pipe section loss value analysis permission list, determining that the user has the pipe section loss value analysis permission, and sending a first query response to the terminal; and if the user identification is not included in the pipe segment loss value analysis permission list, determining that the user does not have the pipe segment loss value analysis permission, and sending a second query response to the terminal. The terminal receives a first query response or a second query response sent by a metering management server of the natural gas storage and transportation system; and the terminal determines that the user has the pipe section loss value analysis authority according to the first query response, and determines that the user does not have the pipe section loss value analysis authority according to the second query response.
The user identification can be a user account number registered by a user in a metering management server of the natural gas storage and transportation system, and the like.
Step 202: and the terminal acquires second data which are measured, handed over and filled in each pipe section in the natural gas storage and transportation system through the PPS system.
The second data for each pipe segment may be a total amount of natural gas for each pipe segment.
Step 203: and the terminal calculates the loss value of each pipe section according to the first data of each pipe section and the second data of each pipe section.
And for each pipe section, the terminal calculates the data difference of the first data and the second data of the pipe section, and the data difference is used as the loss value of the pipe section. For each pipe section, this is calculated, and the loss value of each pipe section is calculated.
Step 204: and the terminal determines the loss threshold of each pipe section according to the service practice.
And (3) storing the loss threshold value of each pipe section in the metering management client of the natural gas storage and transportation system, and in the step, the terminal actually acquires the stored loss threshold value of each pipe section according to the service.
Step 205: and the terminal selects the pipe sections with abnormal loss values from the pipe sections according to the loss values of the pipe sections and the loss threshold values of the pipe sections.
For each pipe section, the terminal determines whether the loss value of the pipe section is larger than the loss threshold value of the pipe section; if the loss value of the pipe section is larger than the loss threshold value of the pipe section, determining that the loss value of the pipe section is abnormal; and if the loss value of the pipe section is not larger than the loss threshold value of the pipe section, determining that the loss value of the pipe section is normal. Therefore, the step can be:
and the terminal selects the pipe sections with the loss values larger than the loss threshold value from the pipe sections according to the loss values of the pipe sections and the loss threshold values of the pipe sections.
Step 206: and the terminal gives an alarm to the pipe section with the abnormal loss value.
And the terminal acquires an alarm mode and alarms the pipe section with the abnormal loss value through the alarm mode.
The method for acquiring the alarm mode by the terminal and alarming the pipeline section with the abnormal loss value by the alarm mode can be realized by the following first mode or second mode, and for the first mode, the method for acquiring the alarm mode by the terminal and alarming the pipeline section with the abnormal loss value by the alarm mode can be as follows:
and the terminal acquires a preset alarm mode and alarms the pipe section with the abnormal loss value through the preset alarm mode.
The preset alarm mode can be that first prompt information is sent to a preset mailbox address or a preset telephone number, and the first prompt information comprises an identifier of the pipe section with the abnormal loss value; the preset alarm mode can also be displaying second prompt information, wherein the second prompt information comprises the identification of the pipe section with the abnormal loss value; the preset alarm mode can also be playing a warning tone, wherein the warning tone comprises the identification of the pipe section with the abnormal loss value.
For the second implementation manner, the step of acquiring the alarm manner by the terminal and alarming the pipe section with the abnormal loss value by the alarm manner may be:
and the terminal acquires the abnormal degree of the pipe section with the abnormal loss value, selects an alarm mode corresponding to the abnormal degree, and alarms the pipe section with the abnormal loss value through the alarm mode corresponding to the abnormal degree.
The step of acquiring the abnormal degree of the pipe section with the abnormal loss value by the terminal may be:
and the terminal calculates the difference between the loss value of the pipe section and the loss threshold value of the pipe section, and acquires the abnormal degree of the pipe section from the corresponding relation between the difference range and the abnormal degree according to the difference.
The degree of abnormality can be divided into three grades of yellow, red and black; the yellow grade indicates that the loss value of the pipe section slightly exceeds the loss threshold value of the pipe section; the red grade indicates that the loss value of the pipe section seriously exceeds the loss threshold value of the pipe section; the black level indicates that the loss value of the pipe section has been extremely abnormal.
In the embodiment of the invention, the problems and the defects of the metering and the distribution of the natural system storage and transportation pipe network are analyzed by comparing the first data of each pipe section acquired by the SCADA system with the second data of each pipe section acquired by the PPS system, so that the analysis and the early warning of the transmission loss value of the whole pipe network are realized, and the support is provided for improving the metering management level of the natural system storage and transportation pipe network.
