The first trigger unit 102 is connected to the first operation unit 101, and is configured to generate a first trigger signal according to an action of the first operation unit 101, wherein each time the first operation unit 101 acts, the first trigger unit 102 generates a first inverted trigger signal having a level opposite to that of the first trigger signal generated last time. It is understood that the previous action of the first operation unit 101 causes the first trigger unit 102 to generate the first trigger signal, and the present action of the first operation unit 101 causes the first trigger unit 102 to generate the first inverse trigger signal, which is opposite in level to the first inverse trigger signal. For example, if the previous operation generates a high level signal, the current operation generates a low level signal; when the previous action generates a low level signal, the current action generates a high level signal.
The first trigger unit 102 includes a switch circuit (not shown), which is disposed between the power supply 105 and the control unit 103.
The switch circuit comprises a first metal elastic sheet 1021 and a second metal elastic sheet 1022, wherein the alarm pull rope is mechanically connected with the second metal elastic sheet 1022, one end of the first metal elastic sheet 1021 is electrically connected with the control unit 103 through a first pin and a second pin, one end of the second metal elastic sheet 1022 is electrically connected with the power supply 105, and the other end of the second metal elastic sheet 1022 is in contact with or separated from the other end of the first metal elastic sheet 1021 when the alarm pull rope is pulled, so that the circuit connection between the power supply 105 and the control unit 103 is switched on or switched off, and the first trigger unit 102 provides a corresponding trigger signal for the control unit 103.
The first operation unit 101 is configured to control switching of the on and off states of the switch circuit to turn on or off the circuit connection between the power supply 105 and the control unit 103. That is, each time the alarm cord is pulled, the first metal spring plate 1021 and the second metal spring plate 1022 are switched between a contact state and a separation state, so that switching of a switch circuit between a closed state and an open state is controlled, and a circuit connection between the power supply 105 and the control unit 103 is switched on or off, so that the first trigger unit 102 outputs a high-level trigger signal and a low-level trigger signal according to the closed state and the open state of the switch circuit, respectively.
It can be understood that when the alarm pull cord is pulled to make the first metal elastic piece 1021 contact with the second metal elastic piece 1022, the switch circuit of the first trigger unit 102 is closed (i.e. the circuit formed by the power supply 105, the first trigger unit 102 and the control unit 103 is turned on), so that the high-level signal provided by the power supply 105 can continue to be transmitted backwards, and the high-level signal is transmitted to the control unit 103 through the first pin, and at this time, the signal received by the control unit 103 is changed from the first trigger signal (low-level signal) to the first inverse trigger signal (high-level signal); when the alarm pull cord is pulled to separate the first metal elastic piece 1021 from the second metal elastic piece 1022, the switch circuit of the first trigger unit 102 is turned off (i.e. the circuit formed by the power supply 105, the first trigger unit 102 and the control unit 103 is turned off), a low level signal is generated, and the low level signal is transmitted to the control unit 103 through the second pin, and at this time, the signal received by the control unit 103 is changed from the first trigger signal (high level signal) to a first reversed phase trigger signal (low level signal).

When the alarm pull rope is loosened, the positions of the first metal elastic piece 1021 and the second metal elastic piece 1022 are unchanged (cannot be automatically reset), and the trigger signal is unchanged.
When the alarm pull cord is pulled again, the positions of the first metal elastic piece 1021 and the second metal elastic piece 1022 change (i.e., contact changes to separation or separation changes to contact), and the signal received by the control unit 103 changes from a high-level signal to a low-level signal or changes from a low-level signal to a high-level signal.
And a control unit 103, connected to the first trigger unit 102, for receiving the first trigger signal generated by the first trigger unit 102, and configured to output a start signal for starting the alarm function whenever the received first trigger signal generated by the first trigger unit 102 becomes the first inverse trigger signal.
That is, since the alarm cord cannot be automatically reset, when the first trigger signal generated by the first trigger unit 102 received by the control unit 103 is changed into the first inverted trigger signal, the start signal is output, so as to avoid continuous alarm and realize that the alarm can be realized each time the alarm cord is pulled. When the alarm pull rope does not act, the trigger signal generated by the first trigger unit 102 is not changed, and the control unit 103 does not output a starting signal, so that the energy consumption of the alarm is greatly reduced, the using effect is good, and the use is more convenient.
And the alarm unit 104 is connected with the control unit 103 and is used for executing an alarm function according to the starting signal output by the control unit 103. The alert unit 104 includes a communication module for sending alert information to a target client.

And after every alarm, though the alarm pull rope can not reset, the Bluetooth chip can also automatically enter the dormant state, and the alarm can not be continuously given to the user, so that the effect of reducing the power consumption is achieved. Wherein, which kind of level signal shields, which kind of level can awaken up the bluetooth chip, adopts software logic to realize control.
And the power supply 105 is connected with the first triggering unit 102 and used for supplying power to the first triggering unit 102.

It is understood that the previous action of the first operation unit 201 causes the first trigger unit 202 to generate the first trigger signal, and the present action of the first operation unit 201 causes the first trigger unit 202 to generate the first inverse trigger signal, which is opposite in level to the first inverse trigger signal. For example, if the previous operation generates a high level signal, the current operation generates a low level signal; when the previous action generates a low level signal, the current action generates a high level signal.
The first trigger unit 202 includes a switch circuit (not labeled), and the switch circuit is disposed between the power supply 207 and the control unit 205.

And the first pin and the second pin are interlocked, namely when the first pin is conducted, the second pin is disconnected, and when the second pin is conducted, the first pin is disconnected so as to eliminate the mutual influence of the first pin and the second pin, realize the mutual independence of the transmission of the high-level trigger signal and the low-level trigger signal and reduce the interference.
When the alarm pull rope is loosened, the positions of the first metal elastic sheet 2021 and the second metal elastic sheet 2022 are unchanged (cannot be automatically reset), and the trigger signal is unchanged.
When the alarm cord is pulled again, the positions of the first metal elastic sheet 2021 and the second metal elastic sheet 2022 change (i.e. contact changes to separation or separation changes to contact), and the signal received by the control unit 205 changes from a high level signal to a low level signal or from a low level signal to a high level signal.

That is, since the alarm cord cannot be automatically reset, when the first trigger signal generated by the first trigger unit 202 received by the control unit 205 is changed to the first inverted trigger signal, the start signal is output to avoid continuous alarm and realize alarm every time the alarm cord is pulled. The alarm button may be automatically reset, so that the control unit 205 outputs the start signal whenever it receives the second trigger signal generated by the second trigger unit 204. When the alarm pull rope does not act, the trigger signal generated by the first trigger unit 202 is not changed, and the control unit 205 cannot output a starting signal, so that the energy consumption of the alarm is greatly reduced, the using effect is good, and the use is more convenient. When the alarm button does not act, the second trigger unit 204 does not generate the second trigger signal, and the control unit 205 does not output the start signal, thereby further reducing the energy consumption. The first trigger unit 202 and the second trigger unit 204 are different from the control unit 205 in connection circuit, so that the alarm pull rope and the alarm button cannot interfere with each other and cannot affect each other, and the energy consumption is further reduced.

step S101: each time the first operating unit 101 operates, the first trigger unit 102 generates a first inverted trigger signal having a level opposite to that of the first trigger signal generated previously and transmits the first inverted trigger signal to the control unit 103.
Specifically, since the alarm cord is not automatically reset when the first operating unit 101, i.e., the alarm cord, is released. Therefore, when the alarm pull cord is pulled, the switch circuit of the first trigger unit 102 is turned on or off.
In the first case: when the alarm cord is pulled, the switching circuit of the first trigger unit 102 is switched from the off state to the on state, and the generated trigger signal changes from a low level signal to a high level signal.
In the second case: when the alarm cord is pulled, the switching circuit of the first trigger unit 102 is switched from the on state to the off state, and the generated trigger signal changes from a high level signal to a low level signal.
When the alarm pull cord is pulled, the trigger signal generated by the first trigger unit 102 is a high level signal or a low level signal. When the alarm pull rope is pulled, and the trigger signal generated by the first trigger unit 102 is a high level signal, the high level signal is transmitted to the control unit 103 through the first pin, and the second pin is disconnected at the same time, so that the second pin does not affect the first pin, and at this time, the signal received by the control unit 103 is changed from the first trigger signal (low level signal) to a first reverse phase trigger signal (high level signal). Correspondingly, when the alarm pull rope is pulled, and the trigger signal generated by the first trigger unit 102 is a low level signal, the low level signal is transmitted to the control unit 103 through the second pin, and the first pin is disconnected, so that the first pin does not affect the second pin, and at this time, the signal received by the control unit 103 is changed from the first trigger signal (high level signal) to a first reverse phase trigger signal (low level signal). That is to say, the first pin and the second pin are interlocked, so that mutual influence of the first pin and the second pin is eliminated, mutual independence of transmission of a high-level trigger signal and transmission of a low-level trigger signal is realized, and interference is reduced.
Step S102: each time the first trigger signal generated by the first trigger unit 102 received by the control unit 103 becomes a first inverted trigger signal, a start signal for starting the alarm function is output and sent to the alarm unit 104.
Illustratively, when the trigger signal generated by the first trigger unit 102 received by the control unit 103 changes from a low level signal to a high level signal or from a low level signal to a high level signal, it indicates that the alarm pull cord is pulled, so the control unit 103 outputs an activation signal for activating the alarm function and sends the activation signal to the alarm unit 104. And because the warning stay cord can not reset automatically when being loosened, so after the start signal sends, the control unit 103 can shield the first trigger signal received at present and automatically enter the dormant state, until receiving the first opposite-phase trigger signal with opposite level, the control unit 103 can only awaken up to realize that the warning stay cord can both report to the police when being pulled at every turn. And after the alarm is finished every time, although the alarm pull rope cannot be reset, the control unit 103 also automatically enters a dormant state, and the alarm cannot be continuously given out, so that the effect of reducing the power consumption is achieved.
Step S103: the alarm unit 104 performs an alarm function upon receiving the activation signal.
The alert function may be sending an alert signal to a client or other alert function.
Step S104: the alarm unit 104 sends alarm information to the target client.
The client is an APP or a WeChat applet and the like installed on a guardian or a family mobile phone, a tablet computer and other mobile equipment.
The alarm method provided by the embodiment comprises the following steps that every time the first operation unit 101 acts, the first trigger unit 102 generates a first reverse trigger signal with the level opposite to that of the first trigger signal generated last time and sends the first reverse trigger signal to the control unit 103; outputting a start signal for starting an alarm function and sending the start signal to the alarm unit 104 whenever the first trigger signal generated by the first trigger unit 102 received by the control unit 103 becomes a first inverted trigger signal; the alarm unit 104 performs an alarm function upon receiving the activation signal. The alarm function can be started by each action of the first operation unit 101, and the alarm function is not started when the first operation unit 101 does not act. Low energy consumption, good use effect and more convenience.
EXAMPLE five
Referring to fig. 7, on the basis of the second embodiment, the present embodiment provides an alarm method of the alarm device 200 according to the second embodiment, including:
step S201: each time the first operation unit 201 operates, the first trigger unit 202 generates a first inverted trigger signal having a level opposite to that of the first trigger signal generated previously and sends the first inverted trigger signal to the control unit 205.
Specifically, since the alarm cord is not automatically reset when the first operation unit 201, i.e., the alarm cord, is released. Therefore, when the alarm cord is pulled, the switch circuit of the first trigger unit 202 is turned on or off.
In the first case: when the alarm cord is pulled, the switching circuit of the first trigger unit 202 is switched from the off state to the on state, and the generated trigger signal changes from a low level signal to a high level signal.
In the second case: when the alarm cord is pulled, the switching circuit of the first trigger unit 202 is switched from the on state to the off state, and the generated trigger signal changes from a high level signal to a low level signal.
When the alarm cord is pulled, the trigger signal generated by the first trigger unit 202 is a high level signal or a low level signal. When the alarm pull cord is pulled, and the trigger signal generated by the first trigger unit 202 is a high level signal, the high level signal is transmitted to the control unit 205 through the first pin, and the second pin is disconnected at the same time, so that the second pin does not affect the first pin, and at this time, the signal received by the control unit 205 is changed from the first trigger signal (low level signal) to a first inverse trigger signal (high level signal). Correspondingly, when the alarm pull cord is pulled, and the trigger signal generated by the first trigger unit 202 is a low level signal, the low level signal is transmitted to the control unit 205 through the second pin, and at the same time, the first pin is disconnected, so that the first pin does not affect the second pin, and at this time, the signal received by the control unit 205 is changed from the first trigger signal (high level signal) to a first reverse phase trigger signal (low level signal). That is to say, the first pin and the second pin are interlocked, so that mutual influence of the first pin and the second pin is eliminated, mutual independence of transmission of a high-level trigger signal and transmission of a low-level trigger signal is realized, and interference is reduced.
Step S202: each time the second operation unit 203 is operated, the second trigger unit 204 generates a second trigger signal and sends it to the control unit 205.
Specifically, each time the second operation unit 203, i.e., the alarm button, is pressed, the circuit among the power supply 207, the second trigger unit 204 and the control unit 205 is turned on, so that the high-level signal provided by the power supply 207 can be continuously transmitted back through the second trigger unit 204, i.e., the second trigger unit 204 generates the second trigger signal (high-level signal).
Step S203: each time the control unit 205 receives a first trigger signal generated by the first trigger unit 202 and becomes a first inverted trigger signal or receives a second trigger signal generated by the second trigger unit 204, a start signal for starting an alarm function is output and sent to the alarm unit 206.
Illustratively, when the trigger signal generated by the first trigger unit 202 received by the control unit 205 changes from a low level signal to a high level signal or from a low level signal to a high level signal, it indicates that the alarm pull cord is pulled, so the control unit 205 outputs an activation signal for activating the alarm function and sends the activation signal to the alarm unit 206. And because the warning stay cord can not reset automatically when being loosened, so after the start signal sends, the control unit 205 can shield the first trigger signal received at present and automatically enter the dormant state, until receiving the first opposite-phase trigger signal with opposite level, the control unit 205 can awaken up, in order to realize that the warning stay cord can both report to the police when being pulled at every turn. And after the alarm is finished every time, although the alarm pull rope cannot be reset, the control unit 205 also automatically enters a dormant state, and the alarm cannot be continuously given out, so that the effect of reducing the power consumption is achieved.
Each time the control unit 205 receives the second trigger signal generated by the second trigger unit 204, the control unit 205 outputs a start signal for starting the alarm function and sends the start signal to the alarm unit 206.
It can be understood that the second trigger unit 204 can only generate the second trigger signal when the alarm button is pressed, and the control unit 205 automatically enters a sleep state to reduce power consumption when the alarm button is released, and does not send out the start signal. The second triggering unit 204 can generate the second triggering signal again only when the alarm button is pressed again.
Step S204: the alarm unit 206 performs an alarm function upon receiving the activation signal.
The alert function may be sending an alert signal to a client or other alert function.
Step S205: the alert unit 206 sends alert information to the target client.
The client is an APP or a WeChat applet and the like installed on a guardian or a family mobile phone, a tablet computer and other mobile equipment.
It should be noted that the functions of the control unit 205 and the alarm unit 206 may be implemented by one bluetooth chip. Therefore, referring to fig. 8, another flow diagram of the alarm method is provided in this embodiment.
The alarm method provided by the embodiment comprises that every time the first operation unit 201 acts, the first trigger unit 202 generates a first inverted trigger signal with the level opposite to that of the first trigger signal generated last time and sends the first inverted trigger signal to the control unit 205; each time the second operation unit 203 is actuated, the second trigger unit 204 generates a second trigger signal and sends it to the control unit 205; when the control unit 205 receives a first trigger signal generated by the first trigger unit 202 and becomes a first inverse trigger signal or receives a second trigger signal generated by the second trigger unit 204, a start signal for starting an alarm function is output and sent to the alarm unit 206; the alarm unit 206 performs an alarm function upon receiving the activation signal. The alarm function can be started by each action of the first operation unit 201 and the second operation unit 203, and the alarm function is not started when the first operation unit 201 and the second operation unit 203 do not act. Low energy consumption, good use effect and more convenience.
