Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic flowchart of a charging control method for a wireless sensor according to an embodiment of the present invention, please refer to fig. 1, in which an energy storage module supplies power to the wireless sensor, and the charging control method for the wireless sensor may include the following steps:
step S110: and detecting the voltage of the energy storage module.
Step S120: and when the voltage of the energy storage module is lower than a preset first threshold value, controlling the solar cell panel to charge the energy storage module.
Wherein the preset first threshold is smaller than the maximum allowable charging voltage of the energy storage module.
The energy storage module provided by the embodiment of the invention is used for supplying power to the wireless sensor (all units inside).
In a preferred embodiment of the present invention, the setting of the threshold value for the voltage of the energy storage module includes: the maximum allowable charging voltage Vmax of the energy storage module is used for preventing the problem of battery overcharge; the maximum allowable standby charging voltage Vst of the energy storage module is the maximum voltage allowed by the energy storage module when the energy storage module is charged by the standby power supply module; the minimum allowable voltage Vmin of the energy storage module is used to prevent the problem of over-discharge of the battery. Hereinafter, each threshold value may be represented by Vmax, vst, and Vmin correspondence, and a description thereof will not be repeated.
The energy storage module is the battery mostly, and after the battery reached certain electric quantity, it can be slower to charge, and reserve power module has life's restriction, consequently is charging the battery through reserve power module, and the battery stops to charge the battery when reaching certain electric quantity (for example, 70% of Vmax). Thus, the setting of Vst can be less than or equal to the setting of Vmax, e.g., vst can be set to 70% of Vmax.
Wherein the preset first threshold is smaller than the maximum allowed charging voltage Vmax of the energy storage module. The preset first threshold may be set according to various actual parameters of the energy storage module, for example, may be set to Vmax-0.05V.
By way of example, under the condition of sufficient sunlight, the solar panel (which converts solar energy into electric energy) is controlled to access, the received electric energy is adjusted, and after the received electric energy is adjusted to be suitable for the voltage of the energy storage module, the solar panel is controlled to charge the energy storage module; or when the voltage of the energy storage module is reduced to a preset first threshold (for example, reduced to Vmax-0.05V) along with the consumption of the wireless sensor, controlling the solar panel to be connected, and charging the energy storage module through the solar panel.
Step S130: and when the voltage of the energy storage module reaches the maximum allowable charging voltage, controlling the solar panel to stop charging the energy storage module.
By way of example, under the condition that sufficient sunlight is monitored, the electric energy consumed by the wireless sensor is smaller than the electric energy charged by the solar panel, so that the voltage of the energy storage module gradually increases along with the increase of the electric energy until the maximum allowable charging voltage Vmax is reached, and at the moment, the solar panel is turned off to charge, so that the over-charging of the energy storage module is prevented; when the voltage of the energy storage module is reduced to a preset second threshold value (for example, reduced to Vmax-0.05V) along with the consumption of the wireless sensor, the solar panel is switched in again, and the energy storage module is charged through the solar panel.
Step S140: and when the voltage of the energy storage module is lower than a preset second threshold value, controlling the standby power supply module to charge the energy storage module.
The preset first threshold is greater than the preset second threshold, and the preset second threshold is greater than the minimum allowable voltage of the energy storage module.
The preset second threshold is greater than the minimum allowed voltage Vmin of the energy storage module. The preset second threshold may be set according to actual parameters of the energy storage module, for example, may be set to Vmin +0.05V.
By way of example, when the solar panel cannot receive enough sunlight, for example, when an extremely severe environment occurs, continuous rainy weather, sand and dust cover the solar panel, the solar panel is damaged, and the like, the solar panel cannot charge the energy storage module for a long time, the electric quantity of the energy storage module is gradually consumed due to continuous power consumption of the wireless sensor, and further the voltage of the energy storage module is reduced, and when the voltage of the energy storage module is monitored to be lower than a preset second value (for example, less than or equal to a minimum allowable voltage Vmin + 0.05V), the standby power supply module is started to charge the energy storage module, so that the wireless sensor can normally work.
Preferably, after step S130, the method for controlling charging of a wireless sensor may further include: and when the voltage of the energy storage module reaches the maximum allowable standby charging voltage, controlling the standby power supply module to stop charging the energy storage module, wherein the maximum allowable standby charging voltage is less than or equal to the maximum allowable charging voltage of the energy storage module.
And after the above example is carried out, the standby power supply module is started to charge the energy storage module, and the standby power supply module is controlled to stop charging the energy storage module until the voltage of the energy storage module reaches the maximum allowable standby charging voltage Vst.
Preferably, after the controlling the backup power supply module to stop charging the energy storage module, the charging control method for the wireless sensor may further include: and controlling the solar cell panel to charge the energy storage module.
The above example is carried out, after the standby power supply module is controlled to stop charging the energy storage module, the solar panel is connected, normal power supply of the solar panel is controlled to be recovered, if the voltage of the energy storage module is reduced to a preset second threshold value (for example, reduced to Vmin + 0.05V) again, it is indicated that the solar panel still cannot work normally, and then the standby power supply module is controlled again to charge the energy storage module.
In a preferred embodiment of the present invention, when the standby power supply module is controlled to charge the energy storage module, the charging control method for the wireless sensor may further include: and sending a signal for starting the standby power supply module to a main control unit so that the main control unit records the times of starting the standby power supply module.
By way of example, when the standby power supply module is controlled to be charged, a signal may be sent to the main control unit to notify the main control unit that the standby power supply module charges the energy storage module. The main control unit may record the number of times of starting the standby power supply module, for example, the number of times of charging the standby power supply module is +1; the node (wireless sensor node) can also be uploaded to an upper computer in a charging state through a standby power supply module so as to prompt that the charging electric quantity of the current energy storage module is insufficient for an operator or a patrol worker, and the fault needs to be checked on site.
Further, the main control unit records the charging times of the energy storage module by the standby power supply module, and if the charging times upper limit allowed by the standby power supply module is reached, an alarm can be sent to the upper computer to prompt an operator or patrol and examine personnel to replace the standby power supply module.
Therefore, according to the charging control method of the wireless sensor provided by the embodiment of the invention, under a severe environment condition, when the solar cell panel cannot be normally charged for a long time and the voltage of the energy storage module is reduced to a certain extent to influence the work of the wireless sensor, the standby power supply module can be controlled to charge the energy storage module, so that the cruising ability of the wireless sensor is improved, and the adaptability of the wireless sensor to the severe environment is enhanced; the embodiment of the invention can also send a standby power supply module starting signal to the main control unit to inform an upper computer to prompt an operator or a patrol worker that the charging electric quantity of the current energy storage module is insufficient and the fault needs to be checked on site; furthermore, the main control unit can perform early warning before the electric quantity of the standby power supply module is exhausted by recording the starting times of the standby power supply module so as to prompt operating personnel or inspection personnel to replace the standby power supply module, and the reliability of the wireless sensor system is further improved.
An embodiment of the present invention further provides a charging control device, where the charging control device may include: a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the charging control method of the wireless sensor according to any one of steps S110 to S130.
The processor comprises a kernel, and the kernel calls a corresponding program unit from the memory. One or more than one kernel can be set, and the charging control method of the wireless sensor described in any one of steps S110 to S130 is implemented by adjusting kernel parameters.

The main control unit 20 receives the data collected by the wireless collecting unit 30, and then transmits the wireless signal to an upper computer (for example, a terminal or a relay) through the wireless communication unit 21, and the upper computer analyzes and processes the received data. The standby power supply module 12 is electrically connected to the battery management unit, and when the electric quantity (voltage) of the energy storage module 13 is too low (lower than a preset second threshold value, for example, less than or equal to the minimum allowable voltage Vmin + 0.05V), the battery management unit controls the standby power supply module 12 to charge the energy storage module 13, and the battery management unit may further send a start signal of the standby power supply module 12 to the main control unit 20.

Then, when the solar cell panel cannot receive enough sunlight, the solar cell panel cannot input electric energy to the battery management unit, and at the moment, the wireless sensor system supplies power through the electric energy stored by the energy storage module.
