As shown in connection with fig. 10, in some alternative embodiments, the controller assembly 800 further includes: a detection component 810, an acquisition module 820, and a control module 830. The detection component 810 is configured to detect a flow value through the water meter; the obtaining module 820 is configured to obtain a value of the flow through the meter detected by the detecting component 810; the control module 830 is configured to control the supply of power to one of the hydro-power generation assembly 300 and the battery 700 based on the flow value. Therefore, the flow value of the water meter flowing through and detected by the detection component 810 can be obtained, the flow value has a large influence on the generated energy of the hydroelectric generation component 300, the hydroelectric generation component 300 or the storage battery 700 is used for supplying power under the control of the flow value, accordingly, the water meter can be directly supplied with power through the hydroelectric generation component 300 under the condition of sufficient flow value, the abnormal operation of the water meter due to insufficient power supply under the condition of small flow value is avoided, the problem that the storage battery 700 needs to be repeatedly charged due to the fact that the storage battery 700 is used for supplying power at any time is avoided, the service life of the storage battery 700 is influenced, the replacement period of the battery is prolonged, and the water meter works more stably.

Alternatively, the first set threshold is determined by the power consumed in the electricity unit of the water meter and the power generated by the hydro-power generation assembly 300. Thus, since the electricity consumption unit of the water meter has a certain consumption power, and the hydroelectric generation assembly 300 is used for supplying power, the generated power of the hydroelectric generation assembly 300 is required to meet the consumption power of the electricity consumption unit of the water meter, and the water meter can be normally used, and the generated power of the hydroelectric generation assembly 300 is related to the flow rate value of the water flow, so that the first threshold value is related to the consumption power of the electricity consumption unit of the water meter and the generated power of the hydroelectric generation assembly 300, and the generated power of the hydroelectric generation assembly 300 can be better supplied to the electricity consumption unit of the water meter for use.
Alternatively, in the case where the value of the flow rate through the water meter is the first set value, the generated power of the hydro-power generation assembly 300 is equal to the consumed power in electricity units of the water meter.

For example, when the power consumption of the water meter per electricity unit is 1 watt per hour, and the flow rate through the water meter is 0.4 cubic meters per hour, the amount of electricity generated by the hydroelectric power generation module 300 is 1 watt per hour, and the first set value is 0.4 cubic meters per hour.

The detecting component 810 is used for detecting water flow, the transmitting component is used for transmitting detected data, and the displaying component is used for displaying a water flow value detected by the detecting component 810.
Alternatively, the hydro-power generation assembly 300 is connected to the battery 700 through a first circuit switch, to the electricity consumption unit of the electricity meter through a second circuit switch, and the battery 700 is connected to the electricity consumption unit of the electricity meter through a third circuit switch. Thus, the hydroelectric generation assembly 300 or the storage battery 700 can control the electricity supply of the electricity utilization unit of the electricity meter by controlling the opening or closing of different circuit switches.
Optionally, the control module 830 is configured to control the second circuit switch to be turned off and the third circuit switch to be turned on when the power is supplied from the battery 700. In this way, the second circuit switch is controlled to be closed, the connection between the hydroelectric generation assembly 300 and the electricity consumption unit of the water meter is disconnected, the third circuit is controlled to be opened, the storage battery 700 and the electricity consumption unit of the water meter are communicated, the storage battery 700 can supply power to the electricity consumption unit of the water meter, and meanwhile, the influence of the hydroelectric generation assembly 300 on the power supply of the storage battery 700 is avoided.
Optionally, the control module 830 is configured to control the third circuit switch to be closed and the second circuit switch to be opened when power is supplied by the hydro-power generation assembly 300.

Alternatively, where power is supplied from the battery 700, the control module 830 is configured to control the hydro-power generation assembly 300 to charge the battery 700. Like this, when utilizing battery 700 to supply power, can adopt hydroelectric generation subassembly 300 to charge battery 700, compensate the electric quantity loss of battery 700, keep the sufficiency of battery 700 electric quantity, keep the stability of battery 700 power supply, avoid electric power extravagant simultaneously, energy-concerving and environment-protective improves the life of battery 700, and improves the stability of water gauge work.
Optionally, the control module 830 is configured to control the hydro-power generation assembly 300 to charge the battery 700 by activating the first circuit switch. Thus, the storage battery 700 is communicated with the hydraulic power generation assembly 300 by controlling the opening of the first circuit switch, the storage battery 700 is charged by the hydraulic power generation assembly 300, the electric quantity of the storage battery 700 is kept sufficient, the electric quantity loss of the storage battery 700 is prevented, and the service life of the storage battery 700 is prolonged.
Optionally, after the obtaining module 820 obtains the flow value flowing through the water meter detected by the detecting component 810, the method further includes: the obtaining module 820 obtains the electric quantity of the storage battery 700; the control module 830 is configured to control the hydro-power generation assembly 300 to charge the battery 700 based on the current and flow values of the battery 700. Therefore, the electric quantity of the storage battery 700 and the flow value flowing through the water meter can be obtained, whether the storage battery 700 is charged by the hydroelectric generation assembly 300 or not is controlled according to the electric quantity of the storage battery 700 and the flow value flowing through the water meter, the use frequency of the storage battery 700 is reduced while the electric quantity of the storage battery 700 is kept sufficient, the service life of the storage battery 700 is prolonged, and the replacement period of the storage battery 700 is prolonged.
Optionally, the obtaining module 820 obtains the electric quantity of the battery 700 by: the voltage of the battery 700 is acquired, and the electric quantity of the battery 700 is determined based on the voltage of the battery 700. Thus, the charge amount of the battery 700 is correlated with the voltage, and by obtaining the voltage of the battery 700, the charge amount of the battery 700 can be determined more easily and accurately.
Optionally, a voltage stabilizing unit is arranged between the storage battery 700 and the electricity utilization unit of the water meter. Therefore, as the voltage of the storage battery 700 changes along with the reduction of the electric quantity, the voltage can be kept stable through the voltage stabilizing unit, power is supplied better, and the stability of the power supply of the storage battery 700 is improved.
Alternatively, in the case where the flow value is less than the first set threshold or greater than the second set threshold, and the electric quantity of the battery 700 is less than or equal to the first set electric quantity, the control module 830 is configured to control the hydroelectric power generation assembly 300 to charge the battery 700. Thus, when the flow value flowing through the water meter is too small or too large, whether the storage battery 700 needs to be charged or not is judged, and at the moment, the hydroelectric generation assembly 300 is controlled to charge the storage battery 700, so that the electric quantity of the storage battery 700 is kept sufficient, the power supply stability of the storage battery 700 is improved, the service life of the storage battery 700 is prolonged, and the replacement period of the storage battery 700 is prolonged.
Alternatively, the second set threshold is determined based on the power consumed in the electricity usage units of the water meter, and the hydro-power generation assembly 300 generates power ten percent higher than the power consumed in the electricity usage units of the water meter if the flow rate value is the second set threshold. In this way, when the water flow rate is the second set threshold value, the generated power of the hydro-power generation unit 300 is higher than the consumed power of the water meter in electricity consumption, and at this time, the generated power of the hydro-power generation unit 300 is excessive, and when the stored amount of the battery 700 is detected to be small, the battery 700 can be charged with the excessive generated power, so that the utilization rate of energy is improved, sufficient amount of electricity is kept in the battery 700, and the battery 700 is prevented from being short of electricity, thereby improving the service life of the battery 700. For example, if the water flow rate is 0.5 cubic meter per hour, the generated power of the hydro-power generation assembly 300 is higher than ten percent of the consumed power of the electricity consumption unit, the second set value is 0.5 cubic meter per hour, and if the water flow rate is higher than 0.5 cubic meter per hour, the power of the storage battery 700 is low, the hydro-power generation assembly 300 is controlled to supply power to the storage battery 700.
Alternatively, in the case where the amount of electricity of the battery 700 is equal to the second set amount of electricity, the control module 830 is configured to control the hydro-power generation assembly 300 to stop charging the battery 700. Thus, when the electric quantity of the storage battery 700 reaches a high electric quantity, the charging of the storage battery 700 by the hydroelectric generation assembly 300 is stopped, the service life of the storage battery 700 is prevented from being damaged due to the overcharge of the storage battery 700, the service life of the storage battery 700 is prolonged, and the replacement cycle of the storage battery 700 is prolonged.
Optionally, the power of the battery 700 is divided by a percentage, the first set power is greater than or equal to twenty percent and less than or equal to forty percent, and the second set power is greater than or equal to ninety-five percent. Thus, the amount of electricity of the storage battery 700 is generally lower than twenty to forty percent, which may cause electricity exhaustion in the absence of water flow, thereby affecting normal use of the water meter, while the amount of electricity of the storage battery 700 is more sufficient than ninety-five percent, which may cause heat generation of the battery and affect the service life of the battery.
Alternatively, the control module 830 is configured to adjust the generated power of the hydro-power generation assembly 300 to the set power if it is determined that the amount of power of the battery 700 is greater than the first set amount of power and the flow value is greater than the second set threshold. Thus, when the electric quantity of the storage battery 700 is larger than a certain electric quantity and charging is not needed, the flow flowing through the water meter is too large, and the generated energy of the hydraulic power generation assembly 300 is too large, the generated power of the hydraulic power generation assembly 300 is adjusted at the moment because the pressure of flowing water in the water pipe can be consumed by the power generation of the hydraulic power generation assembly 300, waste caused by too large generated energy is avoided, the loss of the pressure of the flowing water in the water pipe is reduced, and the smoothness of the water flow is improved.
Alternatively, adjusting the generated power of the hydro-power generation assembly 300 to a set power includes adjusting the flow of water to the hydro-power generation assembly 300. Thus, the generated power of the hydro-power generation assembly 300 is related to the water flow rate, the greater the generated power of the hydro-power generation assembly 300, and thus the generated power of the hydro-power generation assembly 300 can be adjusted by adjusting the water flow rate to the hydro-power generation assembly 300.
Alternatively, adjusting the flow of water to the hydro-power generation assembly 300 may include adjusting the opening of a solenoid valve in communication with the hydro-power generation assembly 300. In this way, the flow of water to the hydro-power generation assembly 300 is controlled by the electronic valve, which facilitates control and more accurate regulation.
Optionally, the set power is equal to the power consumed in electricity units of the water meter. Thus, the set power is set to be the same as the power consumption of the electricity consumption unit of the water meter, so that the generated energy of the hydroelectric generation assembly 300 can just keep the use of the electricity consumption unit of the water meter, and the energy waste is avoided.
For example, when the power consumption of the water meter per electricity unit is 1 watt per hour, it is determined that the electricity amount of the storage battery 700 is greater than ninety-five percent, and the flow rate value is greater than 0.5 cubic meter per hour, the flow rate of water to the hydro-power generation module 300 can be reduced, so that the power generation power of the hydro-power generation module 300 is 1 watt per hour.
