Based on this, an embodiment of the present invention provides a power management method, and referring to fig. 2, a flow of the power management method is as follows:
step 200: and under the condition that the preset monitoring period is determined to be reached, the power supply of the detection and analysis module is switched on.
In practical applications, in order to reduce the power consumption of the environment monitoring device in a low power consumption or standby sleep state, increase the endurance time of the environment monitoring device, and reduce the number of times of replacing batteries in the environment monitoring device, the environment monitoring device may periodically turn on the power supply of the detection and analysis module 130 according to a preset monitoring period. Specifically, the environment monitoring device may implement the periodic power-on of the detection and analysis module 130 in, but not limited to, the following two ways:
the first mode is as follows: based on the timer timing mode, the power of the detection and analysis module 130 is periodically turned on according to the preset timing duration, and the detection and analysis module 130 is switched from the power-off state to the working state.
For example: assume that the preset count time period of the timer a is S1. After the power supply 100 of the environment monitoring device is powered on, the timer a is triggered to start timing (at this time, only the timer a is in a working state), after the S1 time period, the timer a outputs an enable signal 1 (i.e., the first enable signal) to the power analog switch 1, the power analog switch 1 is triggered to turn on a circuit between the power supply 100 and the detection and analysis module 130, i.e., turn on the power supply of the detection and analysis module 130, and the detection and analysis module 130 is switched from a power-off state to a working state, wherein the value of S1 can be flexibly set according to different application scenarios and user requirements, and can be set at will.
The second mode is as follows: based on the counting manner of the counter, the power of the detection and analysis module 130 is periodically turned on according to a preset counting value, and the detection and analysis module 130 is switched from the power-off state to the working state.
For example: assume that the preset count value of the counter B is M1. After environment monitoring devices's power was powered on, trigger counter B and begin to count (this moment, only counter B is in operating condition), when counter B's current count numerical value M is M1, counter B exports enable signal 1 (being above-mentioned first enable signal promptly) to power analog switch 1, power analog switch 1 receives the enable signal 1 of counter B output, switch on the circuit between power and the detection analysis module, put through the power of detection analysis module promptly, it switches to operating condition to detect the analysis module from the outage state, wherein, M1's value can carry out nimble setting according to different application scenes and user's demand, can the value wantonly.
Step 210: analyzing the data collected by the detection analysis module, and judging whether the data meet preset control conditions or not; if yes, executing corresponding control operation; if not, the power supply of the detection analysis module is disconnected, and the monitoring of the next monitoring period is started.
In specific implementation, after the power of the detection and analysis module 130 is turned on, that is, after the power of the detector 131 and the power of the main control chip 132 in the detection and analysis module 130 are turned on, the detector 131 and the main control chip 132 are switched to a working state from a power-off state, and the detector 131 starts to collect data and sends the collected data to the main control chip 132. After receiving the data sent by the detector 131, the main control chip 132 analyzes the data, obtains an environmental index corresponding to the specified environmental parameter, and determines whether the environmental index exceeds a preset standard range. Specifically, when determining whether the environmental index exceeds a preset standard range, there may be, but is not limited to, the following two cases:
in the first case: the environmental index is beyond the preset standard range.
In this case, the main control chip 132 determines that the data sent by the detector 131 meets the preset control condition, and sends a third enable signal to the second power analog switch 140, and triggers the second power analog switch 140 to turn on the circuit between the power supply 100 and the communication module 150, that is, to turn on the power supply of the communication module 150, at this time, the communication module 150 is switched from the power-off state to the working state, and under the instruction of the main control chip 132, an alarm message is sent.
Further, the main control chip 132 sends a reset enable signal to the cycle monitoring module 110, and triggers the cycle monitoring module 110 to perform a reset operation, that is, the main control chip 132 triggers the cycle monitoring module 110 to perform the following reset operations: after receiving the reset enable signal, the period monitoring module 110 sends a second enable signal to the first power analog switch 110, and triggers the first power analog switch 110 to disconnect a circuit between the power supply 100 and the detection and analysis module 130, that is, disconnect the power supply of the detection and analysis module 130, and the detection and analysis module 130 is switched from a working state to a power-off state; the cycle monitoring module 110 resets a timer or counter (i.e., the timer or counter is cleared). At this point, the period monitoring module 110 completes the reset operation.
It should be noted that after the main control chip 132 instructs the communication module 150 to send the alarm message, before sending the reset enable signal to the cycle monitoring module 110, the main control chip 132 needs to determine whether the configuration instruction message is received. Thus, if it is determined that the configuration indication message is received, the main control chip 132 may complete corresponding configuration based on the configuration information carried in the configuration indication message, and further implement parameter configuration and/or parameter modification of the environmental monitoring apparatus, optimization and upgrade, and the like. Preferably, after completing the corresponding configuration, the main control chip 132 may further return a configuration completion response message to the sending device of the configuration indication message through the communication module 150.
Further, after the main control chip 132 returns a configuration completion response message to the sending device of the configuration indication message, or after determining that the configuration indication message is not received, it may report data information, such as the data acquired by the detector 131, the environment index corresponding to the specified environment parameter, and a determination result of whether the environment index exceeds a preset standard range, to a specified device (e.g., a central control platform, etc.), and send a fourth enable signal to the second power analog switch 140 when the reporting is completed, trigger the second power analog switch 140 to disconnect a circuit between the power supply 100 and the communication module 150, that is, disconnect the power supply of the communication module 150, and switch the communication module 150 from a working state to a power-off state.
In the second case: the environmental index does not exceed the preset standard range.
In this case, the main control chip 132 does not send the third enable signal to the second power analog switch 140, keeps the communication module 150 in the power-off state, and only sends the reset enable signal to the cycle monitoring module 110, so as to trigger the cycle monitoring module 110 to perform the reset operation, that is, the main control chip 132 triggers the cycle monitoring module 110 to perform the following reset operation: after receiving the reset enable signal, the period monitoring module 110 sends a second enable signal to the first power analog switch 110, and triggers the first power analog switch 110 to disconnect a circuit between the power supply 100 and the detection and analysis module 130, that is, disconnect the power supply of the detection and analysis module 130, and the detection and analysis module 130 is switched from a working state to a power-off state; the cycle monitoring module 110 resets a timer or counter (i.e., the timer or counter is cleared). At this point, the period monitoring module 110 completes the reset operation.
For example: assuming that the preset specified environmental parameter is indoor temperature; the predetermined standard range of the indoor temperature is T1-T2.
After the power supplies of the detector and the main control chip are switched on, the detector and the main control chip are switched to be in a working state from a power-off state, the detector starts to collect data such as indoor temperature, air humidity, air composition, ultraviolet intensity, magnetic field intensity and illumination intensity, and sends the collected data to the main control chip.
The main control chip analyzes the data collected by the detector to obtain the specified environmental parameters: the method includes the steps of determining whether the temperature index T is beyond a standard range T1-T2 corresponding to the indoor temperature, and specifically, when determining whether the temperature index T is beyond the standard range T1-T2, the following two situations may exist but are not limited to:
in the first case: the temperature index T corresponding to the indoor temperature exceeds the standard range T1-T2. In this case, the following operations may be performed, but are not limited to:
step 1 a: the main control chip determines that the data sent by the detector meets preset control conditions, sends an enabling signal 3 (namely the third enabling signal) to the power supply analog switch 2, triggers the power supply analog switch 2 to switch on a circuit between a power supply and the communication module, namely switches on the power supply of the communication module, and the communication module is switched to a working state from a power-off state and sends an alarm message under the indication of the main control chip.
Step 2 a: the main control chip judges whether the configuration indication message 1 is received, if so, the step 3a is executed; otherwise, step 4a is performed.
Step 3 a: and the main control chip completes corresponding configuration based on the configuration information carried by the configuration indication message 1, returns a configuration completion response message 1 to the sending equipment 1 of the configuration indication message 1, and continues to execute the step 4.
Step 4 a: the main control chip reports data (including indoor temperature, air humidity, air composition, ultraviolet intensity, magnetic field intensity, illumination intensity and the like), an environment index (namely a temperature index T) corresponding to a designated environment parameter (namely the indoor temperature), a judgment result that the temperature index T exceeds a standard range T1-T2 and the like to the central control platform.
Step 5 a: the main control chip sends an enable signal 4 (i.e. the fourth enable signal) to the power analog switch 2, and triggers the power analog switch 2 to disconnect a circuit between the power supply and the communication module, i.e. disconnect the power supply of the communication module, and the communication module is switched from a working state to a power-off state.
Step 6 a: the main control chip sends a reset enabling signal to the timer A (or the counter B).
Step 7 a: after receiving the reset enable signal, the timer a (or the counter B) sends an enable signal 2 (i.e., the second enable signal) to the power analog switch 1, and triggers the power analog switch 1 to disconnect a circuit between the power supply and the detection and analysis module, i.e., disconnect the power supply of the detection and analysis module, and the detection and analysis module is switched from a working state to a power-off state.
