Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

In order to solve the problems of low reasonability and low efficiency of electric charge statistics in the prior art, the embodiment of the invention discloses an electric charge statistics method and device. It should be noted that the electricity charge statistical method provided by the embodiment of the present invention may be applied to a back end, and in a specific application, the back end may be a device capable of receiving an internal message and an external message and processing data, such as a centralized controller, a server, a mobile phone, a tablet computer, and a personal computer.

Fig. 1 is a schematic flow chart of an electric charge statistics method according to an embodiment of the present invention. As shown in fig. 1, the method for calculating an electricity charge provided by the embodiment of the present invention may be applied to a back end, where the back end may include a read thread and a write thread, and may include the following steps:

s101, the reading thread receives an internal machine message and an external machine message, and after a synchronous signal is detected, the running time of an external machine and the power consumption of the external machine are counted according to the received external machine message; according to the power consumption of the external machine and the received internal machine information, the power charge of each distributed internal machine is counted; calculating the electricity charge balance of each owner according to the electricity charge of each distributed internal machine;

s102, when detecting that a target owner with the electricity charge balance lower than a preset value exists, the write thread sends a shutdown control instruction to the internal machine owned by the target owner, so that the internal machine owned by the target owner is shut down according to the shutdown control instruction.

The internal machine message may include a power consumption of the external machine, an alarm message, and the like. The rear end can be the equipment that centralized control ware etc. was used for controlling interior machine, outer machine, and the rear end can receive interior machine message and outer machine message to information such as the charges of electricity of statistics interior machine, operating duration, the number of times of starting up also can count outer machine operating duration and outer quick-witted power consumption, can also record interior machine alarm information and outer quick-witted alarm information, thereby the warning inquiry instruction of response front end realizes the management and control to interior machine and outer machine.

The back end can comprise two threads, namely a read thread and a write thread, wherein the read thread can read information of internal and external machines and carry out related operation, the write thread can receive the issue of a front-end control instruction, and when the control instruction is received, the drive layer interface can be called to complete the setting specified by the control instruction. By adopting the mode, through the division and cooperation of the reading thread and the writing thread, even for the operation of the database, which is cpu intensive, and under the condition that the number of the internal and external machines is more (not less than 500), the phenomenon of obvious blockage (2-3s) can not occur, and the control instruction of the front end to the internal and external machines and other self-defined instructions can be responded in time.

The synchronous signal can be generated once every 2 minutes, before the synchronous signal arrives, a reading thread at the rear end can always receive the internal machine message and the external machine message, and after the synchronous signal is detected, the state information of the internal machine and the external machine can be counted; and the internal machine information and the external machine information received 2 minutes before can be discarded every time the internal machine state information and the external machine state information are counted, so that the reading thread can start to receive the next internal machine information and the next external machine information.

If the synchronous signal is generated once every 2 minutes, the electricity charge of the internal machine can be counted once every two minutes, all the information of the internal machine and the information of the external machine at the current moment can be recorded by using the info _ from _ drive _ now variable, the information of the internal machine and the information of the external machine before two minutes can be recorded by using the info _ from _ drive _ pre variable, and the electricity consumption, the running time and the starting times of the internal machine with two minutes can be obtained by comparing the information of the internal machine and the external machine before and after two times. The coll _ message _ turn _ round variable may be used to record the electricity charge statistics of the internal unit after the power is turned on.

For convenience of program maintenance, if some new functional modules are added, the functional modules are mainly used for sending or receiving instructions, if the functional modules are related to the sending instructions, the functional modules can be placed in a writing thread, if the functional modules are related to the receiving instructions, the functional modules can be placed in a reading thread, if the functional modules are not related, the functional modules can be set independently by considering the actual situation.

The rear end can carry out centralized control on an inner machine and an outer machine of the air conditioning unit, and the counted electricity charge of the inner machine can be distributed to an owner of the inner machine. An air conditioning unit may have at least one outdoor unit and at least one indoor unit, and each outdoor unit may provide heating or cooling for the plurality of indoor units. If at least one distributed internal machine is in a working state under one air conditioning unit, the power consumption of the external machine is distributed by each distributed internal machine in the working state.

In addition, the scanning period of the reading line of the rear end to the internal unit and the external unit can be 2 minutes, namely the centralized controller can receive the information of the internal unit and the information of the external unit once every 2 minutes, and the running time and the power consumption of the external unit can be counted by comparing and calculating the currently received information of the external unit and the information of the external unit received last time; the running time of the indoor unit can be counted by comparing and calculating the currently received indoor unit information and the indoor unit information received last time; according to the power consumption of the external machine, the running time of the internal machine, the working state of the internal machine and the distribution condition, the power consumption condition of the internal machine in the scanning period can be obtained.

The statistics on the number of times of starting and the running time of the internal machine may be: after the information of each internal machine is read, the on-off state of each internal machine is recorded, and after two minutes, the on-off state of each internal machine is also obtained and compared, wherein the four conditions are as follows:

starting up and starting up: the startup times are not changed, and the running time is increased by two minutes;

starting up and shutting down: the startup times are not changed, and the running time is increased by one minute by default, namely, a half of the statistical period;

shutdown and startup: the starting time is increased by one, and the running time is defaulted to be increased by one minute, namely, a half of the counting period;

shutdown and shutdown: the number of times of starting up is not changed, and the running time is not changed.

The same manner can be adopted to count the startup times and the running time of the external unit, and details are not described herein.

Because one outdoor unit can mount a large number of indoor units, if the number of the indoor units is too large, the query speed of the front end to the database is easily influenced, and the user experience is influenced. For example, when an external machine is fully loaded to support 4096 internal machines, 4096 pieces of internal machine information are generated by each statistic, and the number of newly generated data in one day of the database can be calculated as follows: 4096 × 30 × 24 ═ 2949120. Millions of data are fatal to an embedded database every day, because in the process of balancing data volume and sql access speed, the database can only bear millions of data at most in the life cycle of a system on an embedded platform. In order to solve the problem, the access speed of each storage medium can be fully optimized, and the data can be statistically optimized at the same time, wherein the specific data statistical optimization mode is as follows:

after the reading program receives the information of the internal machine and the information of the external machine, the electricity charge of the internal machine in the scanning period (2 minutes) can be calculated, after the electricity charge of one internal machine is calculated, the current hour within one day at the current moment is firstly inquired, if the internal machine has no electricity charge record in the current hour, the current record is inserted into an electricity charge detail table, and if the electricity charge record exists, the record value is added with the currently calculated electricity charge to update the record value; if the current time is in an hour transition period, namely the current calculation period is not in the same hour as the previous calculation period, firstly inquiring the day of Greenwich mean time of the current time, if the internal unit has no electricity charge record on the current day, inserting the current record into an electricity charge statistical table, and if the electricity charge record exists, adding the record value with the currently calculated electricity charge to update the record value; and exporting the electric charge detail table to the SD card for storage after entering the next day, and emptying the data in the local table.

The electric charge detail table and the electric charge statistical table are respectively used for storing the electric charge detail of the current day and the statistical condition of the electric charge of the current day; by adopting the mode, only one database data is generated by the machine every day, the size stability of the database is ensured, and the access response speed is high.

When a user inquires the electricity charge of a certain time period at the front end, the attention to the time is coarse granularity, for example, electricity charge inquiry of 5 month 1 to 5 month 15 days can occur with high probability, and inquiry of 12 to 15 points is a small probability event.

In addition, when the database files are stored on different storage media, the database can show different access speeds, specifically, the memory is more than NAND flash and more than SD card.

Firstly, the configuration of a database layer about data cache is carried out, when a database is accessed by using sql statements, in order to improve the access speed, a database interface function can cache partial data into a back-end memory, the size of a database page can be set to be 4KB, the maximum cache page number is 8000 pages, and when the related sql statements are executed, the back end can fully utilize the memory to improve the access speed. The whole database file of the back end can be stored in the NAND flash, but the capacity is limited, and as the electricity charge statistical table in the database is a table which continuously increases along with time, when the running time of the back end exceeds 200 days, the NANDflash can be exhausted in capacity under the condition that an internal machine is fully loaded, so that part of the file in the database can be transferred to the SD card.

In order to further improve the access speed, only data which is 200 days away from the current time can be stored in the local NAND flash, when the back-end running time is less than 200 days, the electricity charge statistical table can be stored in the NAND flash, meanwhile, an identical backup is provided on the SD, when the back-end running time is more than 200 days, every time a piece of data is inserted into the electricity charge statistical table, electricity charge data which is 200 days away is deleted, the data in the NAND flash is kept within 200 days, and the data in the SD card is continuously backed up according to the statistical condition of the current day, so that a complete database file is always kept on the SD card, and when the query time is more than 200 days, the database file on the SD card can be used.

In order to distribute the internal machine to the owner and then count the electricity charge balance of the owner according to the electricity consumption condition of the internal machine, a database charging distribution relation table can be preset. Specifically, the database charging distribution relation table may be set in advance in the following manner: establishing an owner key information table by using the owner key information; establishing an electric charge statistical information table by using the electric charge statistical information of the internal machine; and establishing a database charging distribution relation table according to the owner key information table and the electric charge statistical information table.

For example, the owner key information table may be as shown in table 1 below, the electricity rate statistics information table may be as shown in table 2 below, and the database billing allocation relationship table may be as shown in table 3 below:

TABLE 1

TABLE 2

id	iac_id	exe_time	open_times	kwh_open	cost_open
						Unique orderColumn number	Inner machine serial number	Execution time	Number of times of starting up	Power consumption	Amount of electricity consumed

TABLE 3

id	iac_id	user_id	start_day	end_day	status
						Unique serial number	Inner machine serial number	Owner's serial number	Starting time	End time	Whether or not it is effective

Key information of the owner is recorded in table 1, including a unique serial number, an owner name, an owner telephone, a floor, a state, a remark, an electric charge balance and the like; the counted internal machine state information including the unique serial number, the internal machine serial number, the execution time, the startup times, the power consumption amount (electricity charge), and the like is recorded in table 2; when the internal machine is to be allocated to the owner, at least three pieces of information can be determined, namely the binding relationship between the internal machine and the owner, the existence time of the binding relationship, and whether the binding relationship is valid or not. The binding relationship between the internal machines and the proprietor is complex, the database charging distribution relationship table can keep the historical data of the internal machine distribution relationship, so that the historical power utilization condition of the proprietor can be counted only by query operation, and accordingly, the distribution relationship table shown in the table 3 can be established.

Whether the distribution relation is valid or not is marked to indicate whether the distribution relation is valid at the current moment, if the distribution relation is valid, the electricity charge statistics is carried out on the internal machine, and if the distribution relation is invalid, the internal machine is distributed to other owners.

Through the database charging distribution relation table, the read thread at the rear end can determine the distribution condition of each internal machine, and further can count the currently distributed internal machines, so that invalid data is reduced; when the front end inquires about the electricity consumption condition of the owner in a period of time, all distribution relations related to the owner in the period of time can be found, then the total electricity consumption of the owner can be calculated by accumulating the electricity consumption and the electricity consumption amount of the electricity charge statistical table in the time range of each internal machine corresponding to the distribution relations, and further the electricity charge balance of each owner can be calculated.

Because the distribution relation between the owner and the internal machine may change, if only one field is directly added in the internal machine table to explain the distribution condition of the internal machine, and the start time and the end time field are not added, when the internal machine is redistributed, the attribution condition of the internal machine in different time periods cannot be distinguished, so when determining that the internal machine belongs to a certain owner, the start time and the end time can be recorded. Therefore, in a certain time period, when the attribution of a certain internal machine is changed, the internal machine can be removed when the industry main electricity is counted. In addition, when a business owner is deleted, his historical bills may be kept for 2 or 3 years for inquiry.

When data storage is considered, in order to improve the utilization rate of storage space and the access efficiency, the invention can use a sub-library storage mode, which specifically comprises the following steps: a database is newly built on an SD card to store an electric charge statistical table, the electric charge statistical table is used for storing data generated in the back-end operation process, namely electric charge data to be reserved, the electric charge data which is 1 year away from the current time in the card is read into a memory file system when power is on and started, the memory database is only required to be inquired when the current end requests the electric charge data within 1 year, and the data in the SD card is required to be inquired when the inquiry time exceeds one year, so that the scheme not only stores the space utilization rate and the access efficiency, but also improves the electric charge inquiry efficiency,

if the target owner with the electricity charge balance lower than the preset value exists, the target owner indicates that the electricity charge balance of the target owner is lower, the internal machine owned by the owner cannot be maintained to continue to operate, and therefore a shutdown control instruction can be sent to the internal machine owned by the target owner, and the internal machine owned by the target owner is shut down according to the shutdown control instruction. The preset value may be set in advance according to requirements, and may be 0, for example.

By applying the embodiment of the invention, the centralized control of the internal machine and the external machine is realized, the electric quantity of the internal machine and the electricity charge balance of an owner can be rapidly counted, the internal machine owned by the target owner with the electricity charge balance lower than the preset value is controlled to be powered off, and the reasonable management and control of the internal machine are realized.

In one implementation, the method may further include:

The front end may be a device capable of communicating with the back end, may send control commands to the back end, and may also receive information fed back by the back end for the control commands. The control commands may include commands for modifying the status of the internal machine, commands for locking the remote controller, commands for clearing the external machine electricity meter reading, commands for modifying the configuration information related to the running of the background program, and the like.

For example, the front end may send form data using a get/post method, the back end writes the form data into a relevant environment variable after receiving the form data, and the back end may first parse the form data and store the form data into a relevant structure in a form of value. Establishing a callback function lookup table in a local service program, corresponding to the relationship between the character string and the callback function, and finding processing functions under different links in a table lookup mode so as to provide corresponding services for the front end, wherein the method comprises the following two aspects: firstly, accessing the database to provide basic operations such as related addition, deletion, modification, check and the like, and secondly, completing control or reading related states of the internal machine and the external machine.

The back end can finish centralized control and management of the air conditioner indoor unit and the air conditioner outdoor unit, perform power charge statistics on the distributed indoor units, interact with a front-end user in a web mode, and respond to a front-end request to feed back a processing result immediately.

When the requester logs in with the administrator, the backend can create a cookie "name _ sha 1" in the front-end browser under the condition that the login is correct, and the subsequent communication completes the verification of the login state, the authority and the hash value by means of the cookie.

In one implementation, to implement schedule management of an internal machine, the method may further include:

The preset state setting conditions may include state values of states of an operation mode, a wind speed setting, a temperature setting, whether to swing, an identifier of a locked remote controller, an identifier of an internal unit in the operation mode, and the like. The preset time point may be set in advance according to the requirement, for example, may be 8:00/10:00 per day, and so on. The user may set the preset time point with the front end, or the back end may pre-store a default preset time point.

For example, the operation mode, the wind speed setting, the temperature setting, whether to swing, whether to lock the remote controller, and the state values of the indoor unit identifier in the operation mode are respectively the refrigeration mode, the low speed, 24 ℃, no swing, and the remote controller locking, the indoor unit identifier in the operation mode includes an indoor unit a and an indoor unit b, the preset time point is 8:00 every day, and after the 8:00 every day is reached, the write thread sets the operation mode, the wind speed setting, the temperature setting, whether to swing, whether to lock the remote controller, respectively, as the refrigeration mode, the low speed, 24 ℃, no swing, and the remote controller locking.

By applying the embodiment of the invention, the schedule management can be carried out on the internal machine, and the further reasonable management and control of the internal machine are realized.

In one implementation, the counting, by the reading thread, the power rate of each allocated internal machine according to the power consumption of the external machine and the received internal machine message may include:

When the electricity consumption of each distributed internal machine is counted, the following two types of mutually exclusive logic at the same time are mainly analyzed: one is that the allocated internal machines are in working state, that is, under a certain machine set, there are internal machines allocated to the owner, and at least one of the allocated internal machines is in working state, and the electricity charge of the internal machine in working state among the allocated internal machines can be called as running charge; in another case, none of the allocated internal machines is in an operating state, and in this case, the electricity charge of the allocated internal machines may be referred to as standby charge. For the internal machine which is not allocated, the invention does not calculate the electricity fee.

The calculation of the standby cost is divided into three calculation modes, including: a basal cost mode, a mean distribution mode, and a time distribution mode. The standby fee in the basic fee mode can be borne by the property owner and is not involved in the calculation of the electricity fee of the owner, and the average distribution mode and the time distribution mode can be borne by the owner and are involved in the calculation of the electricity fee of the owner.

In one implementation, the calculating, by the read thread, the running cost of each of the allocated internal units in the operating state according to the power consumption of the external unit may include:

For example, assuming that there are 15 internal machines under a unit and 1 external machine provides cooling/heating of the internal machine, if in a synchronization signal, it can be determined from the received internal machine message that 8 internal machines are in working state, and 1 of the 8 internal machines is allocated to owner a and 3 of the 8 internal machines are allocated to owner B, then the power consumption of the external machine under the unit is only allocated by the four internal machines in working state and allocated to the owner, and the rest of the four internal machines which are not allocated consume the power of the external machine, but do not share the power, so the power consumption of the internal machine in working state of owner a is: 1/4, power consumption of the outdoor unit; the total power consumption of the three internal machines in the working state of the owner B is as follows: 3/4, and power consumption.

The step of calculating, by the read thread, the standby cost of each allocated internal unit according to the power consumption of the external unit may include:

The user can select the current charging mode through the front end, so that the back end can determine the charging mode selected by the user as the current charging mode. The standby charge calculation modes in different current charging modes are different, and the current charging mode may also be designed with other charging modes besides the above-mentioned basic charge mode, average distribution mode and time distribution mode, which is not limited in the present invention. The preset electricity charge calculation formula can be preset according to the actual situation, and the invention is not limited to this.

For example, when there are two allocated internal machines, it is determined at the current time that none of the two allocated internal machines is in the working state in the currently received internal machine message, and before that, one of the allocated internal machines works for 5 hours, and the other allocated internal machine works for 6 hours, then according to the time allocation mode, the power consumption of the first internal machine is: 5/(5+6) times of the power consumption of the external machine, and the power consumption of the other internal machine is as follows: 6/(5+6) times of the power consumption of the outdoor unit; according to the basic charge mode or the average distribution mode, the power consumption of the two distributed internal machines is as follows: 1/2 times of the power consumption of the outdoor unit.

In one implementation, the calculating, by the reading thread, an electricity fee balance of each owner according to an electricity fee of each allocated internal machine includes:

For example, 3 internal machines are allocated to the owner B, the running cost of each internal machine is 50 yuan, the electricity fee amount prestored by the owner is 200 yuan, and the electricity fee balance of the owner B is: 200- (50 x 3) ═ 50 yuan.

In order to facilitate the consulting of the alarm conditions of each internal unit and each external unit, the method further comprises the following steps:

The inner machine message and the outer machine message can respectively comprise inner machine alarm information and outer machine alarm information, and the reading thread can directly extract the inner machine alarm information and the outer machine alarm information after receiving the inner machine message and the outer machine message, so that the inner machine alarm information and the outer machine alarm information can be recorded.

The user can send the alarm query instruction through the front end, for example, the front end can send the alarm query instruction to the rear end after detecting that the user clicks the alarm query button, and then the write thread of the rear end can send the inner alarm information and the outer alarm information to the front end after receiving the alarm query instruction sent by the front end.

By applying the embodiment of the invention, a user can conveniently look up the inner machine alarm information and the outer machine alarm information.

In another implementation, the line reading process may further perform a drop-off detection on the internal machine, and if it is detected that there is an internal machine in a drop-off state, generate drop-off alarm information based on the internal machine in the drop-off state.

The disconnection detection mode can be as follows: for each indoor unit, judging whether the currently received indoor unit information of the indoor unit and the indoor unit information of the indoor unit received last time are both in an offline state; if the indoor unit is in the off-line state, the indoor unit is judged to be in the off-line state, otherwise, the indoor unit is judged not to be in the off-line state. In addition, for each indoor unit serial number in the database, if the received indoor unit information does not include the indoor unit serial number, the indoor unit with the indoor unit serial number is determined to be in an offline state.

In one implementation, the reading process may further generate an electric bill, and the electric bill may include all internal machine historical power consumption details distributed by the owner. In the basic charge mode or the average distribution mode, the electricity bill and the owner's balance may be updated once per hour, and in the time distribution mode, the electricity bill may be updated once per hour and the owner's balance may be updated once per day. By applying the embodiment of the invention, the electric bill and the balance of the owner can be updated in time, and different updating modes are adopted in different modes, so that the user requirements are better met.

Corresponding to the method embodiment, the embodiment of the invention also provides an electric charge statistics device, which is applied to a back end, wherein the back end comprises a read thread and a write thread.

Referring to fig. 2, fig. 2 is a schematic structural diagram of an electric charge statistics apparatus according to an embodiment of the present invention, the apparatus includes:

By applying the embodiment of the invention, the rear end realizes the centralized control of the internal machine and the external machine, can quickly count the electric quantity of the internal machine and the electricity charge balance of an owner, further controls the shutdown of the internal machine owned by a target owner with the electricity charge balance lower than a preset value, and realizes the reasonable control of the internal machine; because the electricity charge statistics is only carried out on the distributed internal machines, the electricity charge statistics is not required to be carried out on the internal machines which are not distributed, the unnecessary electricity charge statistics times are reduced, and the electricity charge statistics efficiency is improved; the reading thread can read the information of the internal machine and the external machine and carry out relevant electricity charge statistical operation, the writing thread can send instructions to the internal machine to control the running state of the internal machine, and the statistical efficiency is further improved through the division and cooperation of the reading thread and the writing thread; in addition, the reading thread carries out statistical operation only after detecting the synchronous signal, thereby avoiding influencing the statistical efficiency due to continuous statistics.
