The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.
It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to fig. 1 and 2, the meter reading system includes a task module, a counting module, an execution module and a determination module, where the task module includes a processor and a communication connection device, the task module is in communication connection with the electric meter and used for compiling and generating a meter reading task, the execution module includes at least one concentrator, the execution module performs reading work on the electric meter and uploads the read electric meter data to the task module through a communication link, the task module may further include a storage unit, and the task module receives an execution record and electric meter data of the execution module and stores the execution record and electric meter data in the storage unit. It should be noted that the task module, the counting module and the judging module can be collectively arranged as a remote computer, and the executing module is controlled to read the electric meter through a communication link, wherein the communication link comprises a wired network or a wireless network, and the communication link preferably adopts a power line carrier or an RFID radio frequency communication link.
The task module executes the tasks including acquiring the priority of the meter reading task, executing the tasks according to the high priority before executing the tasks according to the low priority, and executing different electric meters in sequence from small to large according to the serial numbers of the electric meters when the tasks with the same priority are met in the process of executing the tasks.
It should be noted that the task module presets an initial null running parameter n and an initial re-reading parameter m, and when the electric meter is overtime or communication is interrupted, the execution module executes a null running operation on the electric meter, where the null running operation includes executing a return program on the electric meter, executing a meter reading task on a next meter, and uploading the null running operation of the execution module to the task module and storing the null running operation in the storage unit. It should be noted that, the execution module sets the number of times of the electric meter running empty for the timeout or the communication interruption according to the current running empty parameter of the electric meter, for example, if the current running empty parameter is 5, the running empty operation is performed for 5 times, that is, when the initial running empty parameter is greater than 0, the task module executes a meter reading task to the execution module, the calculation module records the current initial running empty parameter, and subtracts 1 from the current running empty parameter to form a remaining running empty parameter n 1 When the remaining wheel space parameter n 1 When the value is equal to 0, the execution module executes a meter reading task on the meter ammeter according to the priority level, and the meter reading task needs to be saidIt is clear that the initial null parameter n and the initial re-recording parameter m related to the present invention are 0 or positive integers.
It should be noted that, the execution module may set a communication connection duration threshold, and the determination module may determine whether the communication of the electric meter is over time or interrupted according to the connection threshold, in other words, if the communication duration of the execution module and the electric meter exceeds the connection threshold, the determination module determines that the communication of the electric meter is over time or interrupted, performs a round of the air operation on the electric meter, and performs a meter reading task on the next electric meter, so that the time of the electric meter reading process is predictable and controllable by the method, and the problem of low meter reading efficiency caused by communication delay is greatly reduced.
The calculation module records an initial wheel-space parameter n and a residual wheel-space parameter n of each electric meter 1 And saving the data in a storage module, when an ammeter is in communication connection with the execution module, executing meter reading work on the ammeter by the execution module, repeatedly reading the ammeter by the execution module according to an initial re-reading parameter m of the task module, uploading collected meter reading data and a repeated meter reading record to the task module, and saving the data and the repeated meter reading record in the storage module. For example, when the execution module communicates with an electric meter, the task module calculates m meter reading tasks of a first priority of the electric meter according to the calculation module, sets the m meter reading tasks as initial re-reading parameters m, the execution module extracts one of the meter reading tasks of the first priority from the task module to execute the meter reading task, and synchronously re-reading the m meter reading parameters m minus 1 to form residual re-reading parameters m 1 After the execution is finished, one of the first priority tasks is extracted from the task module again to execute the meter reading task, and the residual re-reading parameter m 1 Subtracting 1 to form a new residual double copyParameter m 1 Up to m 1 Equal to 0 or a timeout or interruption of the meter communication. Similarly, for the second priority task of the normal communication ammeter, the operation steps of the first priority are repeated after the first priority task is executed, so that the method can guarantee the efficiency and give consideration to the priority sequence of the meter reading tasks.
It should be noted that, in practical applications, the communication of the electric meter is often unstable, and the electric meter may not maintain normal communication for a certain period of time due to vibration or dust, so to solve the problem, the method of the present invention can effectively improve the reading efficiency of the electric meter by the method of idling and repeated reading of the electric meter, and the specific method is as follows:
s1: presetting an initial wheel-space parameter n and an initial re-reading parameter m;
s2: setting a wheel space for the ammeter with delayed or interrupted communication, and recording a residual wheel space parameter n 1 ；
S3: setting repeated meter reading for the communication normal electric meter, and recording the residual repeated meter reading parameter m 1 ；
S4: judging whether each priority task of each ammeter in the tasks is completed or not; if yes, ending the task; if not, the steps S1-S3 are executed again.
In the process of repeating meter reading in the step S3, when the normal communication of the electric meter is changed into communication delay or interruption, the empty operation is immediately executed, and the initial re-reading parameter m or the residual re-reading parameter m is used 1 Substituted by an initial null parameter n or a residual null parameter n 1 N and m are preferably set as positive integers in the present invention, it should be noted that the replacement process is directed to the re-reading parameters of all priority pending meter reading tasks of the communication delay or interrupt meter, and the replacement process can be implemented by a replacement function such as a hook function, and it should be understood that the kind and the replacement manner of the replacement function are not limitations of the present invention.
Further, when the communication delay or the power meter executes the wheel-empty operation, the execution module executes meter reading work on the next meter according to the priority. Meanwhile, the computing module records the residue of the ammeter caused by the communication delay or interruptionParameter n of wheel space 1 And the residual wheel space parameter is the current wheel space parameter minus 1 until the residual wheel space parameter n 1 Is equal to 0, when n 1 When the value is equal to 1, the task module issues a meter reading task, the execution module executes the meter reading task according to the task priority, when the communication of the electric meter is successful, the task module issues a highest priority task which does not finish meter reading, and the calculation module calculates the number of the highest priority tasks to form a re-reading parameter m. And the execution module sequentially executes the tasks with the highest priority according to the re-copying parameter m until each task with the highest priority is completely executed.
To better illustrate the invention, the invention is exemplified as follows:
defining a first priority task set of a first electric meter as: a. the 11 ，A 12 ，A 13 ，A 14 ，A 15 。
Defining a second priority task set of the first electric meter as: a. the 21 ，A 22 ，A 23 ，A 24 。
Defining the ith priority task set of the first electric meter as follows: a. the i1 ，A i2 ，A i3 ，A i4 ，……A in (i，n∈N+)
Defining a first priority task set of a second electric meter as: b is 11 ，B 12 ，B 13 。
When the execution unit executes A of the first priority task set of the first electric meter 13 During the meter reading task, the electric meters have communication delay or communication interruption, at the moment, the initial re-reading parameter m of the first priority of the first electric meter is 5, and the rest meter reading parameter m 1 To be 2, the execution unit executes a return program and continues to execute the first priority task B of the second electric meter 11 ，B 12 ，B 13 The redo parameters for all priority tasks for the first meter are replaced with the initial round robin parameter N, where N ∈ (0, N +). Each time the wheel-space operation is carried out, the wheel-space parameter is reduced by 1, when n is equal to 0, if the electric meter is still in a communication delay or interruption state, the wheel-space operation is further executed, and if the first electric meter is in a communication state, the task is obtained through the judging moduleTasks in the highest priority task set which are not copied in the first ammeter in the module are executed, namely the remaining tasks in the first priority of the first ammeter: a. the 14 ，A 15 . Wherein, if A 13 The data is not recorded in the storage module, and the judgment module analyzes that A is still required to be executed 13 And the task module is used for acquiring the unexecuted tasks with the same priority from the task module when the task with the first priority of the first ammeter is executed, and executing the meter reading tasks in the task sets according to the priority sequence for the task sets with different priorities.
It should be noted that, if the electric meter enters the normal communication state from the communication overtime or the interrupt state, the round-robin parameter n is replaced by the repeated reading parameter m, the repeated reading parameter corresponds to the number of task sets under the same priority, and the value of m is different between tasks with different priorities.
