Detailed Description
The technical solutions in the present invention are 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.
At present, the sources of water, electricity, gas and heat charge management systems are two types: firstly, a meter supplier provides water supply electric and heat operation enterprises, and secondly, the water supply electric and heat operation enterprises develop by themselves. Different manufacturers of different water electric heat meters and different charging management systems for water supply electric heat operation enterprises are provided, which leads to different sources of the water electric heat charging management systems. The 'measurement law' in China requires that water, electricity, gas and heat meters can be installed and used after being qualified, but the charging management system used by a water, electricity, gas and heat operation enterprise does not have a corresponding policy or standard for detection, calibration or authentication, so that the following problems exist in the compliance of the charging management system: firstly, the sources are different, so that the compliance and the fairness of the system are lack of effective evaluation, the data transfer and the price algorithm are not transparent, and the application program may have a hidden function, a hidden channel/back door, a special function and specific services, so that the data quality and the data safety have risks; secondly, the influence of the working environment change and various interferences of outdoor equipment such as a terminal, an integrated controller and the like, such as the change of temperature and humidity, the aging and drifting of electronic devices, the mobile signals of telecom operators and the like on the reliability of meter counting data acquisition and transmission is not considered; thirdly, in the water meter type evaluation test, the evaluation rule is not formulated according to the requirements of JJF1182-2007 'measuring appliance software evaluation guideline', and the measurement data processing and transmission control software is evaluated. Therefore, the charging management system should be detected, calibrated or authenticated before being put into use, but the current charging management system has no effective means for detection or calibration, and the detection or calibration is generally carried out manually; the manual detection or calibration has the disadvantages of large workload, low efficiency and error in detection or calibration results.
Therefore, aiming at the problems, the technical idea of the application is that a part of mechanical reading in a water, electricity and gas heat meter which is converted into an electric signal is simulated through a standard signal generating module, and a circuit main board of the water, electricity and gas heat meter is simulated through a signal processing module, so that a household water meter, an electric meter, a gas meter and a heat meter can be simulated; when the toll management system is detected or calibrated, the main control module controls the standard signal generating module to generate a standard signal, the standard signal is an electric signal converted by mechanical motion of the meter, the signal processing module processes the standard signal or the electric signal and then sends a processing result to the calibrated toll management system, namely, the toll management system is simulated to acquire meter data, and toll statistics is carried out according to the meter data to realize detection or calibration of the toll management system.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a block diagram of a calibration apparatus according to an embodiment of the present disclosure, which is applied to calibration of a charging management system for supplying water, power, gas or heat, and the apparatus may include an interaction module, a storage module, a main control module, a standard signal generation module, and a signal processing module; the main control module is respectively electrically connected with the interaction module, the storage module and the standard signal generation module; the standard signal generating module is electrically connected with the signal processing module; the signal processing module is in communication connection with the calibrated toll management system.
The interactive module is used for setting test parameters corresponding to different types of water meters, electric meters, gas meters and heat meters and inputting calibration information; and displaying the meter type, the specific model, the test parameters, the actual total amount, the accumulated amount and the comparison result during calibration.
In this embodiment, the interaction module provides a platform for human-computer interaction, and may be a touch display screen, and the touch display screen is a multi-touch display screen, for example, a liquid crystal display module of hannsare company, of which the model is HSD101PWW1-H00, and the liquid crystal display module is 10.1 inches, and the resolution ratio is 1280 × 800. Specifically, a calibrator can configure the type, specific model and corresponding test parameters of the water, electricity and gas heat meter through the interaction module on site; calibration information can be selected or input according to calibration requirements; meanwhile, the test parameters during calibration and the information fed back by the charging management system can be displayed; the information to be displayed can be selected in real time according to the requirement, and the corresponding function is the same as the actual management and sale function of the charging management system.
Illustratively, the calibration of the charging function is carried out on a water meter, an electric meter, a gas meter and a heat meter of the charging management system, the meter type (the water meter, the electric meter, the gas meter or the heat meter), the specific model of the meter type and the specific test parameters corresponding to the model can be set through the interaction module, the required parameters during the function calibration of the charging management system are all input and set through the interaction module, so that the meter type and the specific model can be directly selected through the interaction module during the calibration, the corresponding test parameters can be obtained, and then the calibration is carried out according to the test parameters.
In this embodiment, the test parameters include different combinations of test time, pulse/frequency signals output at different test times, current signals (4 to 20mA), voltage signals (0 to 5/10V), resistance signals (0 to 4000 Ω), and unit price/step price. When the charging management system is calibrated at different functions, the corresponding test parameters are different, and the corresponding test parameters are selected according to the meter type and the specific model, so that the calibration of each function is realized. In practice, the working principle of the water meter is as follows: when the water meter works, water flow pushes the rotary disc to rotate, and a pulse signal is sent to the circuit main board every time the rotary disc rotates, so that when the water meter charging function of the charging management system is calibrated, the signal processing module is the water meter circuit main board, corresponding test parameters are test time, pulse/frequency signals output at different test time and unit price/step price, and instantaneous water and electricity consumption of the water meter with the corresponding model is recorded in a simulated mode through the pulse/frequency signals.
Similarly, for example, when the charging function of the gas meter of the charging management system is calibrated, the signal processing module is a circuit main board of the gas meter, the corresponding test parameters are test time, pulse/frequency signals, current signals, voltage signals and unit price/step price output at different test time, and the instantaneous gas consumption, the actual temperature of natural gas and the actual pressure of natural gas of the gas meter of the corresponding model are recorded by the module through the pulse/frequency signals, the current signals and the voltage signals; when the charging function of the heat meter of the charging management system is calibrated, the signal processing module is a heat meter circuit mainboard, the corresponding test parameters are test time, pulse/frequency signals output in different test time, resistance signals and unit price/step price, and instantaneous flow of heat-carrying media of the heat meter of the corresponding type and loop temperature measurement platinum resistance signals are recorded by the pulse/frequency signals and the resistance signals.
The calibration information includes the type of the meter and the specific type of the meter, for example, when the charging function of a gas meter of a certain type of the charging management system is calibrated, the interaction module selects the gas meter and then selects the corresponding type of the gas meter, so that the test parameters corresponding to the type can be obtained, and the calibration of the charging function can be realized.
And the storage module is used for storing test parameters corresponding to different models of water meters, electric meters, gas meters and heat meters and information data fed back by the calibrated toll management system, wherein the information data comprises accumulated usage and accumulated amount. Through the parameters set by the interaction module, the actual total usage and the actual total amount obtained by integrating the output standard signals (including pulse/frequency signals, current signals, voltage signals and resistance signals) and the unit price/step price, and the accumulated usage and the accumulated amount fed back by the system are stored in the storage module. In this embodiment, the storage module may be a solid-state memory, such as a RAM.
The master control module is used for sending a control instruction to the standard signal generation module according to the input calibration information and the test parameters corresponding to the calibration information; the system is used for calculating the actual total amount and the actual total sum of the meter according to the test parameters; and the system is used for comparing the actual total amount with the accumulated amount and comparing the actual total amount with the accumulated amount to realize the detection or calibration of the system. In this embodiment, the main control module may be a microprocessor, a single chip, a DSP or a PLC controller, etc.
The main control module has three functions, the first is to control the standard signal generating module to send out corresponding standard signals, the meters have different types, specific models and corresponding test parameters, when the calibration information is selected or input according to the calibrated function, the corresponding test parameters can be determined, the main control module generates a control instruction according to the test parameters, and the standard signal generating module is controlled to send out standard signals according with the test parameters through the control instruction; the second function is to calculate the actual total amount and the actual total amount, the number of the standard signals sent in the test time can be known by the test parameters, the actual total amount is obtained by integrating and accumulating the number of the standard signals, and the actual total amount is obtained by combining the unit price/step price, so as to calibrate the system in the following; the third function is to realize the detection or calibration of the system by comparing the actual total amount with the accumulated amount and the actual total amount with the accumulated amount; if the difference between the actual total amount and the accumulated amount exceeds the metering allowable range, the metering of the system is indicated to be inaccurate, if the difference between the actual total amount and the accumulated amount exceeds the pricing allowable range, the charging of the system is indicated to be inaccurate, and the calibration of the metering and charging functions of the system is realized through the judgment of the difference.
And the standard signal generating module is used for sending corresponding standard signals to the circuit main board of the water, electricity, gas and heat meter according to the control instruction.
The calibration functions are different, the standard signals sent by the standard signal generation module are different, the standard signals are generated according to control instructions, and the control instructions are generated according to the meter type, the specific model and the test parameters. Illustratively, when the water meter metering and charging function of the system is calibrated, the standard signal sent by the standard signal generating module is a pulse/frequency signal; when the metering and charging functions of the system gas meter are calibrated, the standard signals sent by the standard signal generating module are pulse/frequency signals, current signals and voltage signals; when the metering and charging functions of the calorimeter of the calibration system are realized, the standard signals sent by the standard signal generating module are pulse/frequency signals and resistance signals.
In order to facilitate the connection between the standard signal generating module and the signal processing module, the standard signal generating module is correspondingly provided with electronic sampling interfaces according to the interface mode of a circuit main board of the existing water, electricity and gas heat meter, and the signal processing module can be dismounted or plugged at any time through the interfaces.
The signal processing module is used for processing the standard signal to obtain a processing result and sending the processing result to the charging management system; and the system is used for receiving the accumulated amount and the accumulated amount fed back by the charging management system. The signal processing module is used for realizing the processing of identification, calculation, recording, storage and the like of standard signals, and in order to reduce the workload of design and more accurately simulate the processing process of meter signals, the signal processing module directly adopts a circuit mainboard of a tested water electric heat meter, namely when the water meter metering and charging functions of the calibration system are realized, the signal processing module adopts the circuit mainboard corresponding to the water meter; when the metering and charging functions of the system ammeter are calibrated, the signal processing module adopts a circuit main board corresponding to the water ammeter; when the metering and charging functions of the system gas meter are calibrated, the signal processing module adopts a circuit main board corresponding to the gas meter; when the metering and charging functions of the heat meter of the calibration system are calibrated, the signal processing module adopts a circuit main board corresponding to the heat meter. The signal processing module is completely consistent with the water, electricity, gas and heat meter, the interface for receiving the standard signal, the standard signal system, the transmission mode and the like are completely consistent with the meters in normal working, and the meters and the corresponding charge management system establish a communication protocol, so that the communication protocol is not required to be written, the signal processing module is not required to be designed, the communication protocol between the calibration device and the charge management system is not required to be rewritten, the workload is greatly reduced, the calibration efficiency is improved, and the calibration accuracy is ensured.
In the existing charging management, a meter and a charging management system both adopt a wireless transmission mode to transmit data.
