An embodiment of the method of the present application is described in detail below with reference to fig. 2.
Fig. 2 is a schematic flowchart of distributed metering charging according to an embodiment of the present application.
Firstly, creating tenant information and setting related configuration information, wherein the main configuration information comprises a function expression needing metering, a function expression needing charging and an independent queue identification needing charging; different room information is created under different tenants, the room information comprises metering terminal information, charging unit price and rules, and different metering terminal information is associated in different rooms, wherein the metering terminals include but are not limited to an electric meter, a water meter and a gas meter; for a metering terminal, real-time metering data needs to be acquired and stored in a database.
Then, a trigger calculation function is created, and a real-time state quantity for the trigger calculation function to occur is acquired. Referring to fig. 3, taking the timing trigger function as the trigger calculation function as an example, the real-time state quantity is the current time for triggering the timing schedule: the method is realized by adopting a quartz framework, the execution is carried out once in 1 minute by default, meanwhile, a global worker thread pool with the specified number of threads is created for executing the judgment logic of each tenant, wherein each thread is used for calculating and inquiring the information list of the metering terminal under different tenants, at the moment, all tenants, the information of the consumption and the cost calculation configuration information are inquired by executing at the fixed time of every minute, then, each tenant is subjected to circular traversal, and the execution is carried out through the threads in the global worker thread pool in the traversal process.
The process executed by each thread is as follows: matching a function expression to be metered of the tenant with a trigger time of the current timing schedule, for example, the function expression to be metered is 0? If the current trigger timing scheduling time is 10 o' clock 15 of a certain day, the current time meets the expression of the function to be metered, and the tenant needs to perform calculation operation of the usage at the moment, all room information below the tenant can be requested to be acquired through an http protocol and the tenant ID, otherwise, if the room information is not matched, the program is terminated; if the current time meets the expression of the function needing to be metered, then continuing to match the current time with the expression of the function needing to be charged (the charging matching rule is consistent with the metering matching rule), if the current time does not meet the expression of the function needing to be charged, indicating that the tenant only needs to calculate the usage but does not need to perform charging operation, setting the identification field of the tenant needing to be an independent queue as false, and assembling the matching result, tenant information and room information into queue data in a json format, such as { "tentld": "10001", "roommid": "782212", "meterType": "elec", "iscalcost": false, isCalcCost is false, which means that the charging is not needed after the usage is calculated; if the current time meets the charging function expression, the tenant needs not only to calculate the usage amount but also to perform charging operation, the independent queue identification field of the tenant is set as true, and the matching result, tenant information and room information are assembled into queue data in a json format, such as { "tentld": "10001", "roommid": "782212", "meterType": "elec", "iscalcost": true, IsCalcCost is true, which indicates that the usage needs to be charged after being calculated.
Referring to fig. 2, a message queue is created, which includes a plurality of independent message queues and a common message queue, where the independent message queues are used to receive queue data that needs to be monitored by creating an independent thread, and the common message queue is used to receive queue data that does not need to be monitored by creating an independent thread; through the configuration judgment of database information 'an independent queue identifier is required' of the tenant, if the independent queue identifier is preset as true, the queue data of the tenant is inserted into an independent message queue based on a JMS standard; and if the required independent queue identifier is preset as false or empty, inserting the queue data of the tenant into the common message queue based on the JMS standard.
Referring to fig. 4, according to the configuration of whether a tenant needs an independent queue identifier, if the independent queue identifier is preset as true, an independent thread is started and created to monitor queue data in an independent message queue where the tenant is located, and an independent work thread pool is created for processing and calculating the queue data; if the independent queue identifier is required to be preset as false or empty, starting a default thread to monitor queue data in a public queue where the tenant is located; the monitoring thread is blocked when no queue data exists, if the queue has data, the obtained queue data is handed to the working thread pool corresponding to the monitoring thread to carry out multithread processing, each thread acquires the information of the metering terminal, calls the latest metering stop code and the installation metering stop code through the ID of the metering terminal, and performing subtraction usage calculation operation, performing storage operation such as accumulation or new addition of usage records of time period according to hour, day and month, meanwhile, the metering stop code is updated and installed in the metering terminal stop code calculation record of the database, and the optimistic lock is used for ensuring the accuracy of the database data calculation, namely, a version field is added in a terminal stop code calculation table maintained in a database, 1 is added after the last calculated stop code is calculated each time, and the safety of the thread is further ensured through the locking of the database.
After the usage calculation is completed, judging whether each metering terminal in the queue needs to be charged or not by acquiring a field of 'charging required' of each metering terminal, if the isCalcCost is false, indicating that charging is not required, executing subsequent codes and directly ending the program; if the iscalcost is true, which indicates that charging operation is required, the information of the unit price of the room, the charging rule and the like is obtained, charging operation is carried out by combining the calculated usage, the cost is finally calculated, storage operation such as accumulation or new addition of the charging record is carried out, and real-time fee deduction operation can be carried out according to the requirement of the user.
As shown in fig. 5, the charging is performed by taking a room as a main body, and there may be a plurality of metering terminals in a room that need to perform the calculation operation and data storage of the usage and charging, so the message queue is also inserted by taking a room as a main body, which indicates which rooms of the tenant need to perform the calculation operation of the usage and charging. The charging process design firstly calculates the usage, then judges whether the charge is calculated or not according to corresponding conditions, and then carries out charging calculation.
Referring to fig. 6, an embodiment of the present application further provides a schematic structural diagram of a distributed metering and charging system, where the system includes a file management module 1, a trigger scheduling module 2, a message queue module 3, and a charging module 4, each of which is an independent deployment module and provides a corresponding service IP and a port to provide resource access and call of http/tcp between the modules; the system comprises a file management module 1, a trigger scheduling module 2 and a charging module 4, wherein the file management module 1 is used for creating tenants and configuring tenant information, the tenant information comprises a function expression to be metered, a function expression to be charged and an independent queue identifier to be independently queued, rooms are created under the tenants and room information is configured, the room information comprises metering terminal information, charging unit price and rules and the incidence relation between the rooms and the metering terminals, and the file management module 1 is also used for updating metering stop code information of the metering terminals into a metering terminal information base in real time and finally providing the metering stop code information for the trigger scheduling module 2 and the charging module 4 to call http interfaces.

The trigger scheduling module 2 is used for creating a trigger calculation function and acquiring a real-time state quantity which enables the trigger calculation function to occur; and comparing the real-time state quantity with the function expression to be metered, screening out the real-time state quantity meeting the function expression to be metered, matching the real-time state quantity with the function expression to be charged, and packaging a matching result, tenant information and room information into queue data. The whole system is realized by taking json queue data as a target, taking a timing trigger function as a trigger condition, carrying out rule matching on tenant information, judging whether the tenant really reaches the calculated time, and sending queue data to the charging module 4 for calculation processing through different message queues. The trigger scheduling module 2 acquires corresponding queue data through the queue data format standard provided by the charging module 4 to assemble, sets whether charging is needed or not through a function expression needing charging, and then inserts the message queue, and the subsequent process does not need excessive development and realization.

Referring to fig. 7, in the prior art, a charging module is arranged to process all queue data, which has the problems of low performance and low calculation efficiency; the method comprises the steps of establishing a plurality of charging modules to perform distributed processing on queue data, relocating a charging module with the same function at any time if the charging service has low performance, configuring a tenant object to be processed by each charging module, and then distributing the charging modules on different servers to process different json data in the message queue at the same time. Therefore, distributed charging can simultaneously process data calculation of rooms below different tenants through multiple threads, the problem of mutual charging influence among the multiple tenants is solved, the calculation efficiency and timeliness can be improved, the calculation delay can be reduced, and the maintenance of later codes is facilitated.
