Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Embodiment one:
referring to fig. 1, which is a schematic flow chart of a data processing method of a flow metering device based on ultrasonic pulse according to an embodiment of the present invention, the flow metering device is installed to a gas pipeline through which gas passes; the data processing method specifically comprises the following steps:
step S1, acquiring fuel gas consumption data of a target user in a preset period time through a flow metering device;
step S2, sending the gas use information obtained according to the gas consumption data to a user side where a target user is located; the gas use information comprises a gas use coordinate table and a function column associated with the gas use coordinate table;
step S3, when the user side starts the rechecking function in the function column, historical parameter information related to the fuel gas consumption data is called from a historical database; the historical parameter information comprises a flow pressure change value in the gas pipeline and the damage degree of the gas pipeline; it should be clear that the flow pressure change value indicated herein may be obtained by performing routine periodic or irregular leakage detection on the gas pipeline, and of course, may also be data obtained by adopting other detection means, which will not be described herein.
S4, judging whether the gas pipeline is in an abnormal state or not according to the historical parameter information;
of course, if the gas pipeline is not in an abnormal state, that is, in a normal state, and no other abnormal conditions such as leakage occur in the history period, the user side is directly sent with a gas use bill matched with the gas consumption data.
S5, if yes, judging whether the target user meets preferential conditions according to the type of the abnormal state;
step S6, if the preferential conditions are judged to be met, the fuel gas consumption data are corrected to obtain a first fuel gas use bill;
and S7, if the preferential conditions are not met, the explanation information corresponding to the abnormal state and a second fuel gas use bill corresponding to the fuel gas consumption data are sent to the user side.
The flow metering device works on the principle that the flow rate of fuel gas is calculated by utilizing ultrasonic pulses by adopting a differential time method, namely, the flow rate of fluid is reflected by measuring the difference between the speeds of ultrasonic signals in forward and backward directions in the fluid.
Specifically, according to the change condition of the gas flow rate in the gas pipeline, the gas pipeline is reflected according to the historical parameter information, and the user needs to pay the gas use cost regularly after using the gas, however, if the gas pipeline is in an abnormal state, the gas consumption data which is finally counted is influenced, and the gas pipeline is particularly leaked, so that deviation between the gas consumption data and the actual gas effective data of the user is caused, namely, only part of the gas consumption data is really utilized by the user, the rest part of the gas consumption data is wasted in a leaked form, but when the gas use bill is finally provided, the gas consumption data is only led out according to the gas consumption data, and the user pays more cost for the gas consumption data with high deficiency.
Therefore, by combining the technical scheme, the function bar for the target user to select and start is additionally attached while the fuel gas consumption data is sent to the user side, so that a feedback path is provided for the user, and the use experience of the user is improved. In addition, by starting the rechecking function in the function bar by the target user, the direct participation degree of the target user on the gas use condition is improved, and meanwhile, the gas consumption data is more reliable, disclosed and transparent.
Further, because the pipe network system has a plurality of gas pipelines, because of the complexity, the condition that each gas pipeline cannot be accurately locked in real time is caused, so that the pipe network system can timely lock one of the plurality of gas pipelines by means of feedback of a user side and perform anomaly detection, the workload of detecting the pipe network system is simplified, and the use experience of a target user is improved. Furthermore, in order to improve the initiative participation enthusiasm of the target user and improve the use experience of the user, the loss of the target user caused by the lack of the pipe network system is compensated by adding preferential conditions, in addition, the auxiliary help can be provided for the perfect maintenance of the pipe network system according to the start-up rechecking function of the user, so that the problem that the pipe network system cannot accurately consider the local problem of the reaction of the specific target user when the pipe network system is detected regularly and comprehensively is avoided, and further, for example, the gas pipeline used by the target user can be kept in a leakage state for a long time before the pipe network system is not detected comprehensively, so that the gas cost of the user is increased and serious potential safety hazards exist.
Preferably, after the gas usage information is sent to the user side, if the user side starts the confirmation function in the function column, judging whether the target user has a condition meeting the preferential condition in the history period;
if yes, judging whether the gas preferential opportunity meeting the preferential conditions is honored;
if the gas preferential opportunity is not honored, sending an invitation signal to a user terminal;
and if the user terminal receives the invitation signal, sending a first fuel gas use bill to the user terminal.
Preferably, the determining whether the target user has a condition satisfying the preferential condition in the history period includes:
if not, the second fuel gas use bill is directly sent to the user terminal.
Preferably, if the abnormal state is at least one of a leakage state and a gas pipeline damage state, it is determined that the target user satisfies the preferential condition.
Preferably, the abscissa of the gas usage coordinate table is the natural time, the ordinate is the gas usage amount associated with the natural time, the non-usage time when the associated gas usage amount in the natural time is zero is defined, and the rest natural time is the usage time; judging whether the target user meets the preferential conditions according to the type of the abnormal state, including:
sending a request matching signal to a user terminal according to the fuel gas consumption;
if the user side receives the request matching signal, controlling the flow metering device to close valves at two ends of the gas pipeline in a first future time period after the corresponding gas usage amount; wherein the first future time period includes a natural time corresponding to the non-use time;
judging whether the flow pressure value of the gas pipeline in the first future time period changes or not;
if yes, judging that the abnormal state is a leakage state, and defining an early warning grade corresponding to the leakage state according to the change value of the flow pressure value;
the early warning grade is sent to a user side and a service platform terminal, and price reduction compensation is carried out on the gas use of a target user at the future moment according to the leakage state;
if the flow pressure value falls within the preset range value, the abnormal state is judged to not meet the leakage state.
Specifically, in the environment of normal use gas, fine flow gas leakage is difficult to accurately identify, and particularly at the use moment, the fine flow gas leakage and the normal small flow gas use behavior can hardly be effectively distinguished in characteristics, so that the fine flow gas leakage is preferably detected at the non-use moment, and meanwhile, the influence on daily use gas of a target user can be reduced.
The gas pipeline is filled with gas under normal conditions no matter when the gas pipeline is in use or when the gas pipeline is not in use, and especially when the gas pipeline is in use, the pipe network system formed by a plurality of gas pipelines receives the gas supplied by the gas supply equipment continuously, so that the real condition of the gas pipeline at the moment is difficult to detect under the action of continuously supplying the gas despite the gas leakage.
Thus, in combination with the technical scheme, the leakage condition detection time of the gas pipeline is set at a non-use time, and the valves at two ends of the corresponding gas pipeline are closed to cut off the communication between the gas pipeline and the rest gas pipelines in the pipe network system and cut off the gas supply of the gas supply equipment to the gas pipeline. For ease of distinction, the isolated gas line may be defined as the target line, so that if the target line itself does not have leakage, the gas pressure inside it remains unchanged. When the structure of the target pipeline is damaged and leakage occurs, the gas pressure is continuously reduced, so that the gas pressure change is related to the damage condition of the gas pipeline, and the accurate judgment on the specific condition of the gas pipeline is realized.
Under the general condition, the internal pressure of the gas pipeline is 2-5 kilopascals higher than the external atmospheric pressure, and when the gas pipeline is not in use, gas consuming equipment at the rear end of the flow metering device is in a closed state, for example, a valve of the flow metering device is closed at the moment, and the pressure in the gas pipeline can be kept unchanged under the state of no leakage point; if a leak exists at the rear end, the gas line pressure will gradually drop until it is the same as the external atmospheric pressure. By this principle, the leakage can be effectively detected by closing the valve at a time when the valve is not in use by the user and detecting the pressure condition of the gas pipeline for a period of time by using the pressure sensor.
Preferably, defining a gas pipeline matched with a target user as a first pipeline, forming a pipe network system by a plurality of gas pipelines, and realizing the connection or disconnection between the pipe network system and the first pipeline by a control valve; the flow metering device comprises an acoustic wave transmitter and an acoustic wave receiver which are matched with each other, and the acoustic wave transmitter and the acoustic wave receiver are arranged in the gas pipeline and are positioned close to the two ends of the gas pipeline and used for detecting the thickness of the pipe wall of the gas pipeline; judging whether the target user meets the preferential conditions according to the type of the abnormal state, including:
controlling the transmitting end of the sound wave transmitter to form a first included angle relative to the pipe wall of the gas pipeline to transmit ultrasonic waves with first frequency;
when the sound wave receiver receives the ultrasonic wave with the first frequency, calculating and obtaining the thickness of the first pipe wall;
after the first preset time, controlling the transmitting end to form a second included angle relative to the pipe wall of the gas pipeline to transmit second frequency ultrasonic waves;
when the sound wave receiver receives the second frequency ultrasonic wave, calculating to obtain the thickness of the second pipe wall;
comparing whether the thickness difference between the first pipe wall thickness and the second pipe wall thickness is larger than a preset difference;
if yes, judging that the abnormal state comprises a gas pipeline damage state;
judging whether the abnormal state still meets the leakage state;
if yes, a maintenance signal is sent to the service platform terminal, and communication between a gas pipeline corresponding to the target user and the pipe network system is closed;
the method comprises the steps of obtaining preset maintenance duration of the service platform terminal, and improving power supply priority of a target user in the preset maintenance duration.
Specifically, the ultrasonic wave is emitted by the sound wave emitter, and an included angle is formed between the emitting end of the ultrasonic wave emitter and the inner wall of the gas pipeline, so that the ultrasonic wave contacts with the inner wall of the first pipeline, is reflected for multiple times, and is finally received by the sound wave receiver. On the contrary, the ultrasonic wave emitted by changing the different included angles between the emitting end and the inner wall contacts the inner wall at different positions of the first pipeline, so that the ultrasonic wave is reflected and finally received by the sound wave receiver. The angle between the acoustic wave emitter and the acoustic wave receiver and the inner wall of the first pipeline is adjusted simultaneously for a plurality of times, so that the internal condition of the first pipeline is detected as fully as possible.
Based on the above analysis, in a specific example, the included angle between the acoustic transmitter and the inner wall of the first pipeline is a preset included angle, so that when the inner wall is not damaged, the ultrasonic wave smoothly enters the acoustic receiver after being reflected by the inner wall for multiple times, in this process, the path that the ultrasonic wave experiences can be defined as a first path, the required duration is a first duration, and when at least one part of the inner wall that the ultrasonic wave is reflected by the inner wall is an irregular surface, i.e. for example, when the inner wall is damaged, the actual path and the first path, the actual duration and the first duration are all deviated.
Further, in order to more accurately obtain the breakage of the first pipe, the breakage may be expressed as an actual breakage length or may constitute an actual breakage area. Therefore, the angles of the ultrasonic transmitter and the ultrasonic receiver are adjusted for a plurality of times, so that the state of the inner wall of the first pipeline can be fully detected along the length of the first pipeline, and the accuracy of the detection result is ensured. When the first pipeline is damaged, the thickness of the pipe wall of the first pipeline is often changed, when the gas is input into the first pipeline to flow in combination with the actual gas passing condition, the first pipeline is limited by the purity problem of the gas, and the pipe wall is worn by the particle impurities, so that the pipe wall is thinned and arranged to be damaged.
In addition, it can be understood that the occurrence of breakage of the first pipeline does not mean that the leakage condition is satisfied at the same time, so when the occurrence of breakage and leakage of the first pipeline is detected at the same time, a maintenance signal is sent to the maintenance platform terminal, so that the gas pipeline can be closed, that is, the communication between the first pipeline and other gas pipelines in the pipe network system is interrupted, in order to avoid the leakage quantity increased by the continuous use of the first pipeline in the leakage state. Because the first pipeline is detected to be damaged and leaked, the target user actively finds out, and the reinspection function in the starting function column is found out, so that the subsequent larger loss caused by leakage and the larger potential safety hazard are avoided in time. Therefore, in order to improve the use experience of the user and to make up for the management defect of the service platform terminal, the waiting period corresponding to the preset maintenance duration can be made, and in order to make up for the situation that the target user cannot normally use the fuel gas in the period, the power supply priority of the user in the period can be improved.
For example, if the utility power is in tension during the period, the power utilization priority of the target user may be higher than the power utilization priority of other users, that is, the power utilization priority of the utility power for the target user is higher than the power utilization priority for other users. Therefore, the compensation measures can also encourage target users at the user end to actively find abnormality according to the respective fuel gas consumption data and feed the abnormality back to the service platform terminal to a certain extent, so that the interaction between the target users and the service platform terminal is greatly improved, the overall safety of the pipe network system is further improved, and the use experience of the target users is ensured.
Preferably, the target user includes electricity identity information, the electricity identity information is divided into a first electricity load and a second electricity load according to different electricity usage, the first electricity load is industrial electricity, and the second electricity load is domestic electricity;
it should be noted that, the economic loss caused by the accidental power failure of the first electric load is far greater than the loss caused by the accidental power failure of the second electric load. For example, the first electrical load may be a large hospital, steelworks or mine, etc., and when the power supply is interrupted, for example, significant economic losses may occur, such as interruption of the power supply will cause personal injury or damage to the primary equipment and difficult to repair for a long period of time, while the second electrical load may be, for example, an air conditioner, advertising light, an electrical water heater, a utility power source, a shop consumer, and when the power supply is removed, economic losses may occur, but the result of the power supply to the second electrical load is predictable and controllable as compared to the above-mentioned effects of the power supply to the first electrical load.
The method for improving the power supply priority of the target user in the preset maintenance duration comprises the following steps:
judging whether the target user is a first electric load or a second electric load;
if the target user is the first electric load, the power supply priority of the power supply is higher than that of the other first electric loads which do not meet the preferential conditions;
if the target user is the second power consumption load, the power supply priority of the power supply is higher than that of the other second power consumption loads which do not meet the preferential conditions;
wherein the power supply priority of any one of the first electrical loads is higher than the power supply priority of the plurality of second electrical loads.
Preferably, the method for improving the power supply priority of the target user in the preset maintenance duration further includes:
calling a plurality of historical gas use bills of a target user in a historical period; wherein the plurality of historical gas usage bills includes a plurality of first gas usage bills and/or a plurality of second gas usage bills;
judging whether the target user meets potential cooperation conditions according to the historical gas use bills;
if yes, judging that the target user is a gas low-demand object, and sending a maintenance allocation offer to the gas low-demand object;
if the gas low-demand object receives an offer agreement in the maintenance allocation offer, the preset maintenance time for the gas low-demand object is prolonged;
after judging that the maintenance allocation offer is successfully sent, adding a cooperation identifier to a user terminal corresponding to the low-demand gas object at the service platform terminal;
and adjusting the power supply priority of the gas low-demand object in the plurality of second power utilization loads according to the generated times of the cooperation marks.
Specifically, by invoking historical gas usage bills to obtain whether the target user's dependence on gas usage is high or low, a determination is made as to whether to send potential co-operating conditions thereto. It can be understood that if the target user has high dependence on the gas, the probability of being able to accept the potential cooperation condition is implicitly indicated to be lower than that of the target user with low dependence on the gas, so that, in order to improve the deployment efficiency of the service platform terminal, only the target user with low dependence on the gas can be considered to send the potential cooperation condition. Specifically, the offer agreement in the maintenance allocation offer is mainly embodied in giving way of the maintenance priority of other target users, and by avoiding other target users, the maintenance priority of the user is delayed or reduced, so that the service platform terminal can maintain the target users with high gas dependence degree, thereby reasonably arranging the maintenance priority according to the dependence degree of actually using the gas, compensating the target users actively giving way in the aspect of electricity consumption, and ensuring reasonable use experience of the target users.
Further, when the counted number of times of cooperation identification is larger, the cooperation degree of the target user is higher, the use priority of the target user in other fields is improved as much as possible, for example, the power supply priority of the commercial power in the technical scheme.
