Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1:
as shown in fig. 1, an implementation flow of an electromagnetic water meter data additional reading method is disclosed, which specifically includes:
s101: the device wakes up.
Specifically, the equipment refers to one or more electromagnetic water meters according to the actual application, and the electromagnetic water meters can wake up themselves according to a preset frequency. The frequency here may be set to 15 minutes, 1 hour, 2 hours, 4 hours, 6 hours. The setting is carried out according to the actual situation.
S102: and reporting the data in the sleep period to a server.
Specifically, in this embodiment, the preset self-awakening frequency is 4 hours, the electromagnetic water meter still acquires data information in the sleep period, and after the electromagnetic water meter is awakened successfully in step S101, the data acquired in the sleep period of 4 hours is subpackaged per hour to the designated server.
S103: judging whether a response is received, if so, entering the next step S105; if not, executing S104: and storing the data to an unreported set.
Specifically, the server receives the data reported by the electromagnetic water meter and then replies a response. If the electromagnetic water meter does not receive the response reply of the server, the electromagnetic water meter records the data packet which does not receive the response, and the time point and the sequence number of the data packet are used as a sequence object to be stored in the appointed set, namely the unreported set. In terms of energy consumption, the unreported set only stores unresponsive sequence objects within 7 days.
S105: and traversing the unreported set and resupplying the data.
Specifically, as described in step S103, in the whole process of reporting data, if there is a case where the server does not respond, the data is stored in the unreported set, the data is reported during the sleep period of the current period after the next electromagnetic water meter wakes up by itself, and then the sequence object whose response is not received in the designated set is traversed, and the data is complemented according to the first-in last-out principle and the time from near to far. Therefore, the data can be effectively prevented from being missed.
S106: judging whether a response is received, if so, executing S107: and clearing the designated sequence object in the unreported set.
Specifically, in the process of this reporting, it still needs to be determined whether a response from the server is received, and if a response from the server is received, the sequence object is deleted from the specified set, that is, the unreported set. Therefore, whether the server receives the response is judged again so as to better determine the connection with the server, and the specified sequence objects in the unreported set are cleared after the response is determined, so that the data can be effectively prevented from being missed.
If not, the next step S108 is carried out;
s108: and sending the supplementary report data again, and circulating for specified times.
Specifically, if the response of the server is not received, the electromagnetic water meter retransmits the data packet until the traversal of the designated set, that is, the set which is not reported, is finished, and generally the data packet is transmitted for 2 times at most. Therefore, the data can be effectively prevented from being missed, and the consideration of the number designation is to prevent the data transmission which needs to be normally reported later from being limited because too many supplementary reports occupy the flow of the data transmission.
S109: a preset command request is sent.
S110: the server responds to whether a preset command exists or not, and if so, the next step S111 is carried out; if not, executing S112: when the running time is over, the sleep is carried out;
s111: the electromagnetic water meter processes a preset command;
s112: and when the running time is finished, the sleep is carried out.
Specifically, after the traversal of the designated set is finished, the electromagnetic water meter sends a preset command request to the server, waits for whether the server responds to the preset command, if so, the preset command is issued to the electromagnetic water meter, the electromagnetic water meter processes the preset command, and if not, the electromagnetic water meter equipment enters a dormant state. The preset command refers to a command issued by the server to the electromagnetic water meter device, and the preset command includes a preset command for data copying. Therefore, in order to report data more accurately, the server needs to determine whether to generate the preset command according to actual conditions. The data supplementary reading is carried out through the preset command, so that the supplementary sending or the correction of the hardware data can be further carried out, and the accuracy of the data of the electromagnetic water meter is further ensured.
Example 2
As shown in fig. 2, it mainly embodies the forming process of the preset command, and the specific method steps are as follows:
s201: the application task in the server background starts.
Specifically, the server background receives data reported by the electromagnetic water meter, and a certain condition is preset to process the reported data.
S202: and recombining all reported data into a new object with descending time according to the unique identification of the electromagnetic water meter.
In this embodiment, all the reported data generally refers to data of the day before the current day. Specifically, each electromagnetic water meter has a unique identifier, which may be, for example, a factory code of the electromagnetic water meter. Each electromagnetic water meter is marked by the identifier and reports data, but the data are generally reported and stored in no order, so that the data reported by each electromagnetic water meter can be combined into a new object according to a time descending order after each electromagnetic water meter is marked by the identifier and reports the data, thereby facilitating the implementation of subsequent steps and the checking of the reported data.
Supplementary copying of data of the electromagnetic water meter requires certain real-time performance, and after zero point is passed, the equipment management application program carries out grouping again on yesterday reported data packets according to the delivery codes of the electromagnetic water meter to create a set A mark-xxx That is, as shown in fig. 7 and 8, the set stores recently reported data in descending order of time, and each set of sequence objects includes time information.
S203: and traversing the set, extracting time information, comparing the time information with the standard time set, and acquiring a new time set T which is not copied back.
Specifically, the last 24 groups of sequence objects are traversed, whether time information is '00' and '23' is extracted, and if the electromagnetic water meter is matched, the yesterday data packet is complete.
If not, copying the standard array, declaring a new object set:
t [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23], traversing 23 groups of sequence objects, extracting time 0,1,2,3 & cndot & cn. If the set T deletes the object, and so on, the last remaining object in the set T is the unreported time point yesterday.
S204: and analyzing the objects in the set T, wherein the objects are larger than a preset threshold value and are stored in the set W to be used as monitored equipment. In this embodiment, the preset threshold is 20.
Specifically, if the number of the objects in the statistical set T is greater than a threshold value, for example, 20, it is determined that a serious fault occurs in the communication of the electromagnetic water meter. And storing the delivery code + date of the electromagnetic water meter as a sequence object into a new set W, wherein the set is an equipment failure set. The fault equipment can be quickly found through the equipment fault set, and later-stage maintenance is facilitated.
S205: and combining the time which is not copied back, issuing a command packet as a preset command, and waiting for the electromagnetic water meter to be awakened.
Combining the unreported time points into an issuing command, namely the preset command described in the embodiment 1, storing the generated preset command in a server, sending the preset command to the electromagnetic water meter after receiving the preset command request of the electromagnetic water meter, and issuing a data packet according to the preset command after the electromagnetic water meter is awakened and the current time node data is executed.
S206: and the electromagnetic water meter wakes up the online, and the equipment combines the data packet to send according to the time which is not copied back in the preset command.
The preset commands comprise commands of not reading time back, and after the electromagnetic water meter is waken up to be on-line, the data packets are combined according to the preset commands and sent.
S207: and (5) destroying a preset command, and waiting for starting a new task. Specifically, after the preset command is processed, the preset command is cleared, and a next new task is started.
Therefore, by the method of setting the preset command, the unreported time point data can be found out in time, and the supplementary reading of the data of the electromagnetic water meter can be better completed. Particularly, by designing the set T and setting a threshold value for the set T, for example, in this embodiment, the threshold value is 20, and when the number of objects in the set T is greater than 20, it is inferred that the communication of the electromagnetic water meter has a serious fault, and then the faulty water meter can be maintained, and the like, so that the accuracy of data acquisition and supplementary reporting is more effectively ensured.
Example 3
As shown in fig. 3, in order to perform data re-copying more accurately, before the preset command is destroyed and a new task is started, other steps are further included, and the whole processing process specifically includes the following steps:
s301: starting an application program task of a server background;
s302: recombining all reported data into a new object with descending time according to the unique identifier of the electromagnetic water meter;
s303: traversing the set, extracting time information to compare with a standard time set, and acquiring a new time set T which is not copied back;
s304: analyzing the objects in the set T, wherein the objects are larger than a preset threshold value and are stored in the set W to serve as monitored equipment;
s305: combining the time which is not copied back, issuing a command packet as a preset command, and waiting for the electromagnetic water meter to be awakened;
s306: the electromagnetic water meter wakes up the online, the equipment combines the data packet to send according to the time which is not read back in the preset command,
s307: judging whether the preset command is processed successfully, if so, executing S312: presetting a command for destroying, and waiting for starting a new task; if not, the next step S308 is executed.
Specifically, steps S301 to S306 are the same as steps S201 to S207 in embodiment 2, that is, the device management application regroups yesterday reporting packets according to the factory code of the electromagnetic water meter after zero point to create a set a mark-xxx As shown in fig. 7 and 8, the set stores recently reported data in descending time order, and each set of sequence objects includes time information. And traversing the last 24 groups of sequence objects, and extracting whether the time information is '00' and '23', wherein if the electromagnetic water meter is matched, the yesterday data packet is complete. If not, copying the standard array, declaring a new object set: t: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23]Traversing 23 groups of sequence objects, extracting time 0,1,2,3, and comparing each time point with the set T.If the set T deletes the object, and so on, the last remaining object in the set T is the unreported time point yesterday. Combining the unreported time points into an issuing command, namely the preset command described in the embodiment 1, storing the generated preset command in a server, sending the preset command to the electromagnetic water meter after receiving the preset command request of the electromagnetic water meter, and issuing a data packet according to the preset command after the electromagnetic water meter is awakened and the current time node data is executed. And if the number of the objects in the statistical set T is more than 20, the communication of the electromagnetic water meter is judged to have serious faults. And storing the delivery code + date of the electromagnetic water meter as a sequence object into a new set W, wherein the set is an equipment failure set. The fault equipment can be quickly found through the equipment fault set, and later-stage maintenance is facilitated. The successful processing of the preset command means that the server sends the preset command, the electromagnetic water meter hardware reports data additionally, and the server analyzes and confirms and destroys the preset command.
S308: judging whether the preset command waiting time is exceeded or not; if yes, executing the next step; if not, returning to the application program task starting step.
Specifically, the process of processing the preset command generally includes that the server successfully sends the preset command, the electromagnetic water meter reports the data additionally, and the server analyzes and confirms that the electromagnetic water meter reports the data additionally according to the preset command and then completes the processing of the preset command. The purpose of setting a preset command waiting time is to stop processing of the preset command in time and to perform a report supplement in other ways, rather than to allow the preset command to respond or process indefinitely and circularly to affect the reporting of subsequent data and cause new data reporting.
S309: the unsuccessful preset commands are reassembled into a new set E.
S310: and traversing the set E to obtain the unique identifier and the date T of the equipment. Specifically, the new set E combines the unretired times, as shown by E in FIG. 9 mark-001， It can be shown that the data of the device 2021-07-20 # 1 point, 5 point, 14 point, 18 point, 2021-07-19 # 01 point, 04 point, 08 point are unsuccessfully processed and require analog data.
S311: and the application program analyzes according to the existing data and simulates the data of the T date.
Specifically, the server acquires the historical data of each point of the electromagnetic water meter at a preset time, and rearranges and stores the historical data to the set RT, namely, the historical data of each point of the electromagnetic water meter at a time of 7 days is copied, and the data is rearranged and stored to the set RT.
And analyzing the positive and negative conditions of the difference value of the flow of each time point and the flow of the previous time point in the electromagnetic water meter of the electromagnetic water meter, wherein the difference value is positive and is negative and is 1, and the difference value is represented by an array R.
The data of the electromagnetic water meter is a fluctuation value delta, the flow of the point needing to be simulated is F, and the flow of the previous point is F1The difference between the flow rates at two points is DeltaF, F = F1+. DELTA F.DELTA.where.delta. epsilon. R[i]K,R[i]K](ii) a K is the linear coefficient of a certain point value for the previous days.
Specifically, F = F1+△F*δ, δ∈[R[i]K,R[i]K]. The flow rate at a certain point is F, and the flow rate at the previous point is F1The flow rate difference is Δ F. The first element of the delta F is the difference value between the second point and the first point acquired by the electromagnetic water meter, the second element is the difference value between the third point and the second point, the third element is the difference value between the fourth point and the second point, and the like. The delta F array records the flow difference of all adjacent points of the electromagnetic water meter. R1, 1,1,1, 1-1]The flow trends from the first flow point to the last flow point of the table at 24 hours a day are recorded, and when i =1, the 1 st flow and 2 nd flow point trends are shown. By analogy, R[i]Indicating the trend of the ith flow and the (i + 1) th flow point. R[i]The value 1 shows that the trend of the ith flow and the (i + 1) th flow is rising, and R[i]And taking the value of-1 to show that the ith flow and the (i + 1) th flow are in a descending trend. K is the linear coefficient of the point value of the previous 6 days, wherein the linear coefficient still takes the empirical value of 0.7,1.5]. When R is 1, delta is [0.7,1.5 ]]Interval random number, when R is-1, delta is [ -0.7, -1.5 [)]Random number between. Therefore, the delta F is analyzed according to the existing data of the electromagnetic water meter, and other missing data of the same day can be simulated as long as one data point of the electromagnetic water meter is known in a certain day.
In this embodiment, since the historical data of each time point in approximately 7 days of the electromagnetic water meter is obtained, K is a linear coefficient of a certain point value in the previous 6 days, as shown in fig. 10 to 14.

Through chart analysis, the difference values of the first observation points fluctuate within the amplitude range of +1.34, and the difference values of the second observation points fluctuate within the amplitude range of-4.3. The difference between the flow of each point and the flow of the previous point is represented by a "1" for positive and a "-1" for negative. Analyzing the positive and negative conditions of the point difference value of the equipment for 7 days to obtain an array R1, 1,1,1, 1- ·]. The data is the fluctuation value delta, the flow rate at the point is F, and the flow rate at the previous point is F1And the difference value of the two-point flow is delta F, and a formula is obtained according to the curve chart: f = F1+△F*δ, δ∈[R[i]K,R[i]K]. The standard of the difference of the delta F is [0.21,1.34,3.6,4.3 … ]]K is the linear coefficient of the point value of the previous 6 days, where the linear system takes the empirical value [0.7,1.5 ]].
