The present application provides a low power consumption control system, as shown in fig. 1, the system comprising: the power management module 110, the RS latch 120, the switch module 130, the power chip 140, the WIFI module 150, and the sensor 160; wherein:

the RS latch 120 includes an input R terminal, an input S terminal, and an output Q terminal, where the input R terminal is connected to the first pin of the sensor 160 and is used for receiving a trigger signal output by the sensor 160; the input S terminal is connected to a first pin of the WIFI module, and is configured to receive a control signal output by the WIFI module 150; the output Q terminal is connected to the switch module 130 and is used for controlling the on-off state of the switch module 130;

one end of the power chip 140 is connected to the switch module 130, and the other end of the power chip 140 is connected to a second pin of the WIFI module; the power chip 140 determines whether to supply power to the WIFI module 150 according to the on state of the switch module 130;

the power management module 110 supplies power to the WIFI module 150 through the power chip 140;

a third pin of the WIFI module 150 is connected to the second pin of the sensor 160, and is configured to receive the trigger signal output by the sensor 160, and output the control signal according to the trigger signal.

A latch is a logic element in a digital circuit with a memory function. Latching is to temporarily store the signal to maintain a certain level state, and binary digital signals "0" and "1" can be recorded in the digital circuit. The RS latch 120 is the most basic latch structure, and in practical applications, it is common to make various modifications and extensions, and at least one input terminal is added as a control signal, and when the signal is active, the latch can continuously input and output data. The circuit diagram of RS latch 120 is shown in fig. 2. as can be seen from fig. 2, RS latch 120 has two inputs, Q and Q^/As can be seen from the figure, the output state does not change when both the input R terminal and the input S terminal are at high level, but only when one of the inputs is at low level, so that the input R terminal and the input S terminal are at low level. This feature of RS latch 120 is utilized in the present application.

WIFI module 150 itself is the chip, has processing function, and this application utilizes WIFI module 150's processing function itself, connects sensor 160 on WIFI module 150's a pin to control RS latch 120 through the control signal of another pin output of WIFI module 150, thereby control the operating condition of self, need not additionally to increase MCU when realizing the low-power consumption of system, the cost is reduced.

The power management module 110 supplies power to the WIFI module 150 through the power chip 140. Specifically, the power management module 110 may be directly connected to the power chip 140, and the RS latch 120 controls the operating state of the power chip 140, so as to control the operating state of the WIFI module 150. For example, when the sensor 160 is not triggered, the signal output by the RS latch 120 cannot activate the power chip 140, so that the power chip 140 does not operate, and even if the path between the power management module 110 and the WIFI module 150 is turned on, the power chip 140 cannot supply power to the WIFI module 150, and the WIFI module 150 does not operate and is in a low power consumption state; after the sensor 160 is triggered, the signal output by the RS latch 120 activates the power chip 140, the power chip 140 supplies power to the WIFI module 150, and the WIFI module 150 normally operates, so that low power consumption of the WIFI module 150 is achieved.

The power management module 110 may also be connected to the power chip 140 through the switch module 130, and the RS latch 120 controls the on state of the path between the power management module 110 and the power chip 140. For example, when the sensor 160 is not triggered, the signal output by the RS latch 120 controls the switch module 130 to be turned off, so as to disconnect the path between the power management module 110 and the power chip 140, so that the power management module 110 cannot supply power to the WIFI module 150 through the power chip 140, and the WIFI module 150 does not work and is in a low power consumption state; after the sensor 160 is triggered, the signal output by the RS latch 120 controls the switch module 130 to be switched on, so as to switch on a path between the power management chip and the WIFI module 150, the power chip 140 supplies power to the WIFI module 150, and the WIFI module 150 normally works, so as to realize low power consumption of the WIFI module 150.

Currently, in order to realize low power consumption of the WIFI smart sensor 160, the low power consumption MCU is added to hardware. When the sensor 160 is not triggered, the WIFI module 150 is controlled to not work by sending a control signal through the low-power-consumption MCU, and the whole machine is in a low-power-consumption state; after the sensor 160 is triggered, the power supply path of the WIFI transparent transmission module is opened through the low-power-consumption MCU through the MOSFET or the Enable pin of the power supply chip 140, the WIFI transparent transmission module is started to work, after a certain time, the low-power-consumption MCU cuts off the power supply path of the WIFI transparent transmission module, and the whole machine returns to the low-power-consumption state. Although the scheme can meet the requirement of low power consumption, the low power consumption MCU is additionally added to the hardware, and the cost is higher.

The application provides a low-power consumption control system based on RS latch 120 receives external sensor 160 trigger signal and WIFI module 150's control signal through RS latch 120, realizes WIFI module 150 and cuts off the power by oneself. The price of the RS latch and the price of the MCU are not in one order, the price of the MCU is usually different from several hundred yuan, and the RS latch is only one electronic component and usually has several gross money, so that the hardware cost is greatly reduced while the low power consumption is realized.

In some embodiments, referring to fig. 2, the switch module 130 includes a P-type MOS transistor; the power management module 110 is connected to the S pole of the MOS transistor, the power chip 140 is connected to the D pole of the MOS transistor, and the Q output end of the RS latch 120 is connected to the G pole of the P-type MOS transistor.

The working principle of the low-power consumption control system provided by the embodiment is as follows:

in a normal standby state, the RS latch 120 is in an initial state of S ═ 0, R ═ 0, and Q ═ 1, at this time, the P-type MOSFET (P-type MOS transistor) is in an off state, the WIFI module 150 has no power input and does not work, and the whole device is in a low power consumption state; when the sensor 160 is triggered, the input state of the RS latch 120 is changed to S ═ 0, R ═ 1, and Q ═ 0, at this time, the P-type MOSFET is in an on state, the WIFI module 150 starts to operate after being powered on, reports relevant information of the sensor 160 and starts an internal timer, determines whether the trigger signal of the sensor 160 is eliminated after a certain time, and if not eliminated (for example, the water sensor 160 is always in a water immersion state), the WIFI module 150 starts a next round of reporting, timing, and determining processes; if the trigger signal of the sensor 160 is eliminated, the WIFI module 150 outputs a control signal, changes the state of the RS latch 120 to S ═ 1, R ═ 0, and Q ═ 1, at this time, the P-type MOSFET is in the off state again, the whole device returns to the standby state, and the above processes are repeated.

In some embodiments, as shown in fig. 3, the switch module 130 includes an enable pin of the power chip 140; the power management module 110 is connected to the power chip 140, and an output Q terminal of the RS latch 120 is connected to an enable pin of the power chip 140.

in a normal standby state, the RS latch 120 is in an initial state of S ═ 0, R ═ 0, and Q ═ 1, at this time, the enable pin of the power chip 140 is not activated, the power chip 140 does not supply power to the WIFI module 150, the WIFI module does not work with power input, and the whole device is in a low power consumption state; when the sensor 160 is triggered, the input state of the RS latch 120 is changed to S ═ 0, R ═ 1, and Q ═ 0, at this time, the enable pin of the power chip 140 is activated, the power chip 140 operates to supply power to the WIFI module 150, the WIFI module starts to operate after being powered on, reports related information of the sensor 160 and starts an internal timer, determines whether the trigger signal of the sensor 160 is eliminated after a certain time, and if not (for example, the water sensor 160 is always in a water immersion state), the WIFI module 150 starts a next round of reporting, timing, and determining processes; if the trigger signal of the sensor 160 is eliminated, the WIFI module 150 outputs a control signal, changes the state of the RS latch 120 to S ═ 1, R ═ 0, and Q ═ 1, at this time, the switching module 130 is in the off state again, the whole device returns to the standby state again, and the above processes are repeated.

The power conversion circuit is used for converting the output voltage of the battery into a voltage suitable for the WIFI module 150. The specific type of the power module can be selected according to actual conditions, and the application is not limited.

In some of these embodiments, the sensor 160 includes at least one of a reed switch, a hall sensor 160, a water sensor 160, and an accelerometer.

When there are multiple sensors 160, the multiple sensors 160 may be connected to the input R terminals of the WIFI module 150 and the RS latch 120. It is understood that WIFI module 150 has a plurality of third pins, each pin being connected to one sensor 160. RS latch 120 changes state when one of sensors 160 is triggered.

The embodiment also provides a low-power consumption control method of the intelligent sensor. Fig. 4 is a flowchart of a low power consumption control method of a smart sensor according to an embodiment of the present application, where the flowchart includes the following steps, as shown in fig. 4:

step 410, initializing a control signal to be in a first state, and initializing a trigger signal to be in a second state, wherein the first state is the same as the second state;

step 420, generating a trigger signal in a third state after the sensor is triggered, and sending the trigger signal to the input R end of the RS latch and the WIFI module, wherein the third state is different from the second state;

step 430, the RS latch outputs a switch control signal to the switch module according to the trigger signal and the control signal;

step 440, the switch module controls a conduction state of a path between the power management module 110 and the WIFI module according to the switch control signal.

The initialization state of the control signal and the trigger signal can be a low level signal, that is, the initial state of the RS latch is S0, R0, Q1, the switch module is in an off state, the WIFI module has no power input and does not work, and the whole device is in a low power consumption state. And after the sensor is triggered, generating a high-level signal in a third state as a trigger signal, and inputting the high-level signal to the input R end of the RS latch and the WIFI module. After the sensor is triggered, the input state of the RS latch is changed into S (0), R (1) and Q (0), the switch module is in an open state at the moment, and the WIFI module is powered on and works.

In some of these embodiments, the method further comprises:

Specifically, the WIFI module starts to work after being powered on, reports relevant information of the sensor and starts an internal timer, judges whether a trigger signal of the sensor is eliminated after a certain time, and starts a next reporting, timing and judging process if the trigger signal of the sensor is not eliminated (for example, the water immersion sensor is always in a water immersion state); if the sensor trigger signal is eliminated, the WIFI module outputs a control signal, the state of the RS latch is changed into S1, R0 and Q1, the P-type MOSFET is in an off state again, the whole machine returns to a standby state, and the processes are repeated.

The low-power consumption control method of the intelligent sensor is specifically realized by referring to fig. 5.

The design logic determines whether to output the control signal by detecting whether the trigger signal is eliminated within a preset time. On the one hand, due to hardware characteristics, the RS latch changes its output only when one of its inputs is low. Since the RS latch is used to latch the output state, R is 0 and S is 0, which will not cause the output Q to change, and the output Q will change only when R is 0, S is 1 or R is 1 and S is 0, which is an inherent characteristic of the latch. Therefore, after the trigger signal of the sensor is eliminated, that is, after R is equal to 0, the output of the RS latch needs to be changed by outputting the control signal S equal to 1, so as to change the operating state of the WIFI module. On the other hand, due to the requirement of software functions, whether the trigger signal of the sensor is eliminated or not is detected by controlling the WIFI module within the preset time, if the trigger signal is eliminated, the control signal is output to the input S end of the RS latch, if the trigger signal is not eliminated, the currently received trigger signal is reported to the mobile electronic equipment, the working state of the WIFI module can be changed and the alarm effect can be achieved through the detection result at the same time, and the alarm effect can be achieved once as long as the trigger signal is detected, so that the alarm can be continuously given if the sensor is always in the trigger state, and the user experience is improved.

The preset time can be one minute, two minutes or three minutes and other time, and the user can set the specific time interval according to the actual situation.

According to the WIFI module, the RS latch is used for receiving the trigger signal of the external sensor and the control signal sent by the WIFI module, the WIFI module is automatically powered off, and the hardware cost is reduced while the low power consumption is realized.
