Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0043] Since the working environment of smart water meters is mostly carried out under harsh conditions, the body protection is also IP68 level or higher waterproof and dustproof design. Therefore, it is generally seldom opened after it is working to prevent the internal damage from the external environment. Therefore, existing smart water meters generally use non-removable batteries for separate power supply. For example, general electromagnetic water meters will issue an alarm in advance when the battery is exhausted. After receiving the information, the staff will bring a new battery to the site for replacement, and the replaced battery cannot be recharged and reused. Due to the particularity of this product, there are problems with insufficient accuracy and insufficient data processing and analysis in the detection of battery life.

[0044] The present invention obtains the rated parameters of the battery to be tested, including the battery capacity; determines the various functional modules of the device on which the battery to be tested is installed, and the frequency and duration of operation of each functional module of the device every day; calculates the power consumption of each functional module based on the duration of operation of each functional module; calculates the total power consumption of one day based on the frequency and power consumption of operation of each functional module in one day; obtains the standard life of the battery based on the battery capacity and the total power consumption of one day. The present invention calculates the total power consumption by analyzing the power consumption of the device under each functional module, and then calculates the service life of the battery, and has high detection accuracy when detecting non-removable batteries.

[0045] Embodiment 1

[0046] Figure 1 A flow chart of a battery life detection method is provided for the first embodiment of the present invention. Figure 1 As shown, the method includes:

[0047] S101. Obtain rated parameters of a battery to be tested, where the rated parameters of the battery include at least battery capacity.

[0048] It should be noted that the rated parameters of the battery to be tested may include the rated voltage of the battery, the battery capacity, the battery brand model, the average current consumption value of the battery in the working state, the average current consumption value of the battery in the standby state, etc. Among them, the rated voltage in the rated parameters of the battery refers to the voltage output when the battery is working normally; the battery capacity refers to the battery capacity in the initial state; the brand model of the battery indicates which manufacturer produced the battery and which batch of products; the average current consumption value of the battery in the working state can usually be obtained through the circuit design parameters or the technical specifications in the electronic equipment manual; the average current consumption value of the battery in the standby state indicates the power consumption of the device equipped with the battery to be tested when it is not transmitting data or working.

[0049] In order to make the solution of this embodiment adaptable to batteries of different manufacturers, models and capacities, this embodiment can mainly obtain the parameters of the battery capacity and the brand and model of the battery in the rated parameters of the battery to be tested.

[0050] S102: Determine various functional modules of the device equipped with the battery to be tested, and the frequency and duration of operation of each functional module of the device every day.

[0051] For the life detection of non-removable and non-rechargeable batteries, first, the various functional modules of the device installed with the battery to be tested can be determined, and the functional modules represent modules that consume electric energy during operation. For example, a device has a communication function module, a heating function module and a standby function module. When the device is in the communication function module, the heating function module and the standby function module, electric energy will be consumed.

[0052] When obtaining the frequency and duration of operation of each functional module of the device every day, the statistical averaging method can be used to obtain the data of the frequency and duration of operation of each functional module of the device every day, or other methods can be used to obtain the frequency and duration data of operation of each functional module.

[0053] Among them, the frequency and duration data of each functional module of the device are obtained by statistical averaging method every day. Specifically, the frequency and duration data of each functional module in the device installed with the battery to be tested within the preset time are counted, and the frequency and duration data of each functional module are averaged to obtain the frequency and duration data of each functional module every day. For example, the total standby time of the device in one month is counted, and the total standby time obtained is divided by the number of days in a month to obtain the duration data of the device in the standby function every day. The frequency and duration data of other functional modules can also be obtained in the same way.

[0054] S103: Calculate the power consumption of each functional module based on the duration of operation of each functional module.

[0055] After obtaining the running time of each functional module of the device every day, the power consumption of each functional module can be calculated. The power consumption can be calculated by obtaining the current and voltage data of each functional module when it is running, and calculating the power of a functional module when it is running through the current and voltage data, and then obtaining the power consumption of the functional module during the running time period. In this way, the power consumption of each functional module during the running time period can be calculated.

[0056] In one embodiment, a corresponding voltage and current sampling circuit may be constructed to collect voltage and current data when the device operates a single functional module to be tested, and then the power consumption of the functional module during operation may be calculated based on the voltage and current data.

[0057] S104: Calculate the total power consumption for the day based on the operating frequency and power consumption of each of the functional modules in the day.

[0058] The total power consumption for one day can be calculated using a preset calculation formula based on the frequency and power consumption of each functional module in the device. For example, assuming that the device only includes a communication function module, a heating function module, and a standby function module, the power consumption of the device when the communication function module is running, the heating function module is running, and the standby function module is running is obtained, and then the total power consumption for one day is calculated based on the frequency of the communication function module running in one day, the frequency of the heating function module running in one day, and the frequency of the standby function module running in one day.

[0059] S105: Obtain a standard life of the battery based on the battery capacity and the total power consumption in one day.

[0060] The standard life of the battery to be tested can be obtained by dividing the battery capacity of the battery to be tested by the total power consumption of the device in a day.

[0061] It should be noted that since the battery life may also be affected by environmental factors, such as ambient temperature and ambient humidity, the battery life is affected. Therefore, this embodiment only performs battery life detection under normal temperature and pressure and preset humidity environment, that is, the detected battery life is the standard life.

[0062] The technical solution of the embodiment of the present invention obtains the rated parameters of the battery to be tested, including the battery capacity; determines the various functional modules of the device installed with the battery to be tested, and the frequency and duration of operation of each functional module of the device every day; calculates the power consumption of each functional module based on the duration of operation of each functional module; calculates the total power consumption of one day based on the frequency and power consumption of operation of each functional module in one day; obtains the standard life of the battery based on the battery capacity and the total power consumption of one day. The present invention calculates the total power consumption by analyzing the power consumption of the device under each functional module, and then calculates the service life of the battery, and has high detection accuracy when detecting non-removable batteries.

[0063] In one embodiment, for a wireless remote transmission smart water meter, the determining of multiple functional modules of a device having the battery to be tested installed, and the frequency and duration of operation of each functional module of the device every day, includes:

[0064] Obtain multiple functional modules of the wireless remote transmission smart water meter every day, which at least include valve action, LCD display, program upgrade, sensor measurement, local data interaction and remote transmission module reporting;

[0065] Statistics on the frequency and duration of operation of various functional modules every day.

[0066] It should be noted that for wireless remote transmission smart water meters that are not removable and cannot be charged, the daily operation of the smart water meters usually includes functional modules such as valve action, LCD display, program upgrade, sensor measurement, local data interaction and remote transmission module reporting.

[0067] Among them, the specific valve action is that when the user's prepaid water is about to run out, the valve closing function can be used to prevent the user from continuing to use water due to arrears; or the water supply company can use the Internet of Things technology to remotely control the valve-controlled water meter, monitor the water use situation in real time, adjust the water pressure, open and close valves, etc.

[0068] The LCD display function of smart water meters is usually not displayed all the time, but displayed when needed. Common display triggering methods are as follows. For example, card insertion wake-up: For common IC card smart water meters, when the user inserts the IC card into the card slot, the LCD screen of the water meter will be awakened, displaying parameters such as the current water purchase amount, remaining water amount, and cumulative water consumption, so that users can understand the water use situation. After a period of no operation, the display will automatically turn off to save power. Button wake-up: Some smart water meters are equipped with buttons. After pressing the button, the LCD screen will light up and display relevant information, such as the remaining water amount, valve status, etc., and will automatically turn off after a certain period of no operation. Periodic automatic display: Some smart water meters will automatically display some key information at regular intervals, such as displaying the remaining water amount at regular intervals every day, and will automatically turn off after a period of display, which can not only allow users to understand water use information in a timely manner, but also reasonably control power consumption. Event-triggered display: When a specific event occurs in the smart water meter, relevant information will be automatically displayed. For example, when the remaining water volume is lower than the set alarm value, the display screen will automatically light up and prompt the user to purchase water in time; when the water meter fails, such as the battery voltage is too low or it is subject to magnetic interference, the corresponding error code or prompt information will be automatically displayed.

[0069] Program upgrades of smart water meters generally require remote upgrades of the smart water meters, and program upgrades are completed by remotely downloading upgrade data packages.

[0070] Smart water meters measure users' water consumption through sensors, such as Hall sensor metering, magnetic induction sensor metering, ultrasonic sensor metering, magnetoresistive sensor metering, and turbine flow sensor metering to measure water flow.

[0071] The local data interaction of the smart water meter can store the user's water consumption data over a period of time.

[0072] The remote transmission module of the smart water meter can upload the user's water consumption data to the data management center.

[0073] In this embodiment, the operation frequency and duration of each functional module of the smart water meter for multiple households in a community within one month can be counted, including the operation frequency and duration of multiple functional modules such as valve action, LCD display, program upgrade, sensor measurement, local data interaction and remote transmission module, and the average value is calculated to obtain the actual operation frequency and duration of each functional module of the smart water meter every day.

[0074] In one embodiment, the power consumption of each functional module is calculated based on the duration of operation of each functional module, including:

[0075] A simulation device equipped with a battery to be tested is used to simulate the power consumption of the wireless remote transmission smart water meter during one operation, including valve action, LCD display, program upgrade, sensor measurement, local data interaction, and remote transmission module reporting.

[0076] It should be noted that a simulation device can be used to simulate the power consumption of valve action, LCD display, program upgrade, sensor measurement, local data interaction and remote transmission module reporting during one operation of a wireless remote transmission smart water meter. For example, a battery can be installed in a spare smart water meter to simulate the power consumption of the smart water meter when running the above functional modules. The voltage and current sampling circuit can be used to collect the voltage and current data when the simulation device runs a single functional module to be tested, and then the power consumption of the functional module when running can be calculated based on the voltage and current data.

[0077] In one embodiment, based on the frequency and power consumption of each of the functional modules in a day, the total power consumption for a day is calculated, including:

[0078] Based on a simulation device equipped with a battery to be tested, the power consumption of each functional module of the wireless remote transmission smart water meter during one operation time and the actual frequency of operation of each functional module of the wireless remote transmission smart water meter per day are simulated to obtain the total power consumption of the wireless remote transmission smart water meter during daily operation.

[0079] It should be noted that a simulation device can be used to simulate the power consumption of each functional module of the wireless remote transmission smart water meter during one operation time, and the actual operation frequency of each functional module of the smart water meter in each day can be calculated to obtain the total power consumption of the smart water meter in one day.

[0080] In one embodiment, obtaining the standard life of the battery based on the battery capacity and the total power consumption of one day includes:

[0081] Divide the battery capacity by the total power consumption in a day to get the standard life of the battery.

[0082] It should be noted that the battery life may also be affected by environmental factors, such as ambient temperature and ambient humidity. Therefore, the battery life test is only performed under normal temperature and pressure and preset humidity environment in this embodiment, that is, the detected battery life is the standard life. The standard life of the battery to be tested can be obtained by dividing the battery capacity of the battery to be tested by the total power consumption of the device in one day.

[0083] In one embodiment, the method further comprises:

[0084] Under different ambient temperatures and different ambient humidities, respectively, a simulation device equipped with a battery to be tested is used to measure the power consumption of each functional module during operation;

[0085] Based on the simulation device installed with the battery to be tested, the power consumption of each functional module of the wireless remote transmission smart water meter during one operation time and the actual frequency of each functional module of the wireless remote transmission smart water meter running every day are simulated to obtain the total power consumption of the wireless remote transmission smart water meter during daily operation;

[0086] The battery capacity is divided by the total power consumption in one day to obtain the minimum life of the battery under different ambient temperatures and different ambient humidities.

[0087] It should be noted that since the battery life may also be affected by environmental factors, such as ambient temperature and ambient humidity, the present embodiment constructs multiple sets of external measurement environments with different ambient temperatures and ambient humidity, and measures the simulation device equipped with the battery to be tested in the constructed external measurement environment. The power consumption of each functional module of the wireless remote transmission intelligent water meter during one operation time and the frequency of each functional module of the wireless remote transmission intelligent water meter actually running every day are measured, so as to obtain the total power consumption consumed by the wireless remote transmission intelligent water meter during daily operation.

[0088] In this embodiment, the ambient temperatures of 75°C, 0°C, and -25°C, and the relative humidity of 20% and 80% can be set. Six groups of external measurement environments combining ambient temperature and ambient humidity are used to detect the total power consumption of the simulation device equipped with the battery to be tested during daily operation. The battery capacity is divided by the total power consumption for one day to obtain the minimum life of the battery under different ambient temperatures and different ambient humidities.
