Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a smart meter management platform based on a preprocessing method according to an embodiment, and includes a system terminal 11, a communication manager 12 and a smart meter device 13;
when detecting that the user triggers the electric meter function button on the client interface, the system terminal 11 sends a function triggering instruction of the electric meter function button to the communication manager 12, triggers page preprocessing operation, stores function response data uploaded by the communication manager 12 in a cache, and reads the function response data from the cache to respond to the function operation instruction after the client interface reads the function operation instruction input by the user;
the communication manager 12 sends the function triggering instruction to the intelligent electric meter device 13, receives function response data fed back by the intelligent electric meter device 13, and uploads the function response data to the system terminal 11;
after receiving the function trigger instruction, the smart meter device 13 generates function response data corresponding to the function trigger instruction, and sends the function response data to the communication manager 12.
The client interface operated by the system terminal 11 may include a web interface, an APP interface, and the like. The user can trigger the ammeter function button of the client interface through clicking and other operations, and can also input information such as a function operation instruction and the like to the client interface. The client interface operated by the system terminal 11 may also respond to various instructions such as a function operation instruction input by the user.
The electric meter function button can comprise a recharging button and the like, and the function response data corresponding to the electric meter function button refers to data related to the electric meter function button in the operation process of the intelligent electric meter. Specifically, the preprocessing method after triggering the page preprocessing operation includes: when a user clicks a certain function button (an ammeter function button), the user enters a function page and triggers corresponding preprocessing operation according to the function. Taking the function button of the recharging button as an example, when a user enters a recharging page to trigger the recharging button, the background simultaneously executes the functions of reading the communication state of the device and the current recharging times of the device, which are required by the recharging function and can be executed in advance, and stores the preprocessing result in the cache. And after the user submits the recharging amount, directly reading the preprocessing result in the cache, directly displaying and informing the user if the preprocessing result finds that the communication state is abnormal, and directly recharging the equipment and directly returning the recharging result if the preprocessing result does not find that the communication state is abnormal. User perception is shielded, processing speed is increased, and user experience is improved.
In one example, the system terminal 11 may include an intelligent terminal such as a computer. The system terminal 11 can set system terminal services, and the system terminal 11 is responsible for interacting with users, and is a system portal, from which all user operations are initiated. The communication manager 12 is responsible for directly interacting with the smart meter device 13 and periodically uploading current parameters (such as function response data) of the device. The communication manager is directly connected with the equipment, the communication speed is high, and the number of the equipment connected below the communication manager 12 is limited, so that the communication manager 12 can read the current parameters of the equipment in a timed polling mode and store the parameters in the preprocessing cache service. The smart meter device 13 is responsible for metering the actual power consumption information of the user.
In the above-mentioned smart electric meter management platform based on the preprocessing method, when a client interface operated by the system terminal 11 detects that a user triggers an electric meter function button, a function trigger instruction of the electric meter function button is sent to the communication manager 12 to trigger a page preprocessing operation, the communication manager 12 sends the function trigger instruction to the smart electric meter device 13 to receive function response data fed back by the smart electric meter device 13 and upload the function response data to the system terminal 11, the system terminal 11 stores the function response data uploaded by the communication manager 12 in a cache, and after the client interface reads a function operation instruction input by the user, reads the function response data from the cache to respond to the function operation instruction, so as to improve the response efficiency of the function operation instruction and improve corresponding user experience.
In one embodiment, a page interface service and a preprocessing cache service are arranged between the system terminal and the communication manager,
the page interface service is responsible for interacting with the system terminal and providing an interface for the system terminal to interact with the intelligent electric meter equipment;
and the preprocessing cache service is responsible for storing a preprocessing operation result for the inquiry of the page interface service, and directly interacts with the intelligent electric meter equipment when the preprocessing cache service is not hit.
Specifically, the page interface service is responsible for the relevant service interaction with the front end (system terminal), and provides an interface for the front end to interact with the real device (smart meter device).
According to one embodiment, the content stored by the preprocessing cache service comprises page preprocessing operation results and function response data uploaded after the communication manager polls the intelligent electric meter device.
In one example, the pre-processing caching service is responsible for storing pre-processing operation results for querying by the page interface service. And when the page interface query cache service is not hit, directly interacting with the intelligent electric meter equipment. The cache service data sources are divided into two types: 1. and preprocessing the operation result of the page. 2. And the communication manager polls the equipment and then sends the equipment. The cache service data storage method is an improved Hash bucket algorithm + bit domain mode. And (4) quickly positioning and storing the preprocessing operation result in a distributed manner by using a Hash bucket algorithm. The bit field method is used for reducing the memory consumption caused by the result of the preprocessing operation with large data volume.
As an embodiment, the preprocessing cache service adopts a hash bucket algorithm to position whether steps required by the smart meter device function triggering instruction are preprocessed or not, and if the preprocessing is finished, the preprocessing operation result is stored in a cache in a distributed manner; the preprocessing operation result comprises a page preprocessing operation result and function response data uploaded after the communication manager polls the intelligent electric meter equipment.
In one example, the improved hash-bucket algorithm may be as described with reference to fig. 2. For example, if f (12) is 0 and f (4) is 0, the hash results collide, and the key-corresponding data are sequentially stored in the linked list. When the data storage position is found, the bucket is found according to the hash function, and the key values are compared in the bucket chain table in sequence. In the case where f (12) — 0, f () denotes a certain function, 12 denotes a function parameter, and 0 denotes that when the parameter 12 is passed to the function, the result obtained by the function is 0. The same holds true for f (12) ═ 0. Here, 12 and 4 are both smart meter device IDs (unique numbers), namely keys. Analogizing the key-value structure in a non-relational database, when 12 is key, value is 0.
Therefore, according to the characteristic that the ID part of the equipment is continuous and is slightly deleted, the time is changed by space after the improvement, the modulus is positioned to the bucket, the position in the bucket is completely removed, and the O (1) complexity is read and updated. For example, a modulo 12% 4-0 is located to bucket 0, a modulo 12/4-3 is located to bucket in position line 3, and a location is located to device 12 information unique storage location via bucket 0 and line 3.
In one embodiment, the communication manager sets a device command queue service; the equipment command queue service is responsible for recording and queuing operation commands of the intelligent electric meter equipment in the same channel in the communication management machine, calculating the estimated execution waiting time of each operation command, and feeding the estimated execution waiting time back to the system terminal for displaying.
The equipment command queue service is responsible for recording and queuing operation commands of the intelligent electric meter equipment in the same channel of the same communication manager, calculating the estimated execution waiting time of each command and displaying the estimated execution waiting time to a user.
In one embodiment, the device command queue services include a synchronous queue and an asynchronous queue; the synchronous queue is used for storing function trigger instructions corresponding to a recharging function, a clearing function and a power-off function respectively; the asynchronous queue is used for storing preset rates and function operation instructions corresponding to time intervals respectively.
The queues serviced by the device command queue are divided into two categories: 1. and the synchronization queue is used for storing commands which need to directly return results, such as recharging, clearing, power-off and the like. 2. And the asynchronous queue stores user non-urgent operation commands such as preset rates and time intervals, and informs the user of an operation result in a callback mode after the processing is finished.
In one embodiment, referring to fig. 3, the communication manager may include a plurality of communication managers, each communication manager may be provided with a plurality of channels, and each channel may be connected to a plurality of smart meter devices. And the communication manager is responsible for directly interacting with the intelligent electric meter and regularly uploading current parameters of the equipment. The communication manager is directly connected with the equipment, the communication speed is high, and the number of the equipment connected below the communication manager is limited, so that the communication manager can read the current parameters of the equipment by adopting a timing polling mode and store the current parameters in the preprocessing cache service. The page interface service, the preprocessing cache service and the device command queue service set by the corresponding intelligent electric meter management platform cooperate together, and are collectively called gateway service, and the structure diagram is shown in fig. 4. The flow of the preprocessing solution of the intelligent electricity meter management platform can be referred to fig. 5.
Wherein, taking the recharging function as an example, the recharging function can be divided into a function point reading communication state, a recharging reading frequency, a recharging frequency after recharging reading and a balance after recharging reading. The pre-processing function points are reading communication state and reading recharging times. The user clicks a recharge button, the preprocessing operation result in the cache is read while the page is loaded, and if the cache data is invalid or the cache is not hit: 1. and queuing according to the communication manager channel to execute the preprocessing function, reading the communication state and reading the recharging times. 2. The communication manager reads the current communication state and the recharging times of the equipment from the cache or directly interacts with the equipment (intelligent electric meter equipment) and returns the current communication state and the recharging times to the upper computer program. 3. And the upper computer program stores the device preprocessing cache result according to the device ID and the Hash method for subsequent use. If the cache is hit and effective, after the user inputs the recharging amount, a recharging command is queued and executed according to the communication manager channel. And returning an operation result to the user after executing the recharging command.
Compared with the existing intelligent ammeter management system, the embodiment has the following technical advantages:
1. enhancing user experience using pre-processing methods
By preprocessing some operations, a user can quickly obtain a processing result after performing the operations.
2. Software cache and hardware cache to improve system processing efficiency
And the information is preprocessed according to the device ID distributed storage device, so that the system processing efficiency is improved.
3. The synchronous and asynchronous priority queues solve the problem of equipment interaction waiting under the channel of the communication manager and provide progress display for users.
The software-controlled channel queuing mode avoids the problem that the hardware device concurrently executes the command and waits for timeout. And the current progress and the estimated waiting time can be calculated out according to the number of commands in the queue, and the information interaction between the current progress and the estimated waiting time and the user is enhanced.
4. The improved hash bucket algorithm + bit field + array method is used for rapidly inquiring, storing and processing results.
5. By using an improved hash bucket algorithm and storing the preprocessing result in a bucket distributed manner by using a hash bucket + bit field + array method, the complexity of searching and storing time can be O (1) even under the condition of large data volume, the storing and searching speed is increased, the system smoothness is improved, and the product performance is improved.
6. Reduce the labor operation and maintenance cost caused by the equipment being unable to execute the operation in parallel
The problem of overtime caused by the fact that the equipment operation cannot be performed in parallel under the same channel of the same communication manager of hardware is solved in a software mode, and the operation and maintenance workload and the cost are reduced.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
