Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
Example one
Fig. 1 is a schematic block diagram of a circuit of a vehicle-mounted alarm 3 provided in an embodiment of the present application, and referring to fig. 1, the circuit of the vehicle-mounted alarm 3 includes:
the wireless transceiver module 1, the controller 2, the alarm 3, the switch circuit 4 and the infrared sensor 5;
the controller 2 is respectively connected with the wireless transceiving component 1, the alarm 3, the switch circuit 4 and the infrared sensor 5;
the wireless transceiving component 1 is connected with a vehicle remote controller in a wireless communication way;
the infrared sensor 5 is disposed inside the vehicle.
It should be noted that, because the vehicle remote controller mostly adopts 315M or 433M frequency, the wireless transceiver module 1 in this embodiment adopts a high frequency processing chip commonly used by 315M and 433M, specifically, but not limited to GR500 chip, and includes functions of receiving and transmitting high frequency signals, amplifying signals, decoding signals, and the like inside.
It should be noted that the wireless transceiver module 1 includes a plurality of pins;
a first pin of the wireless transceiving component 1 is grounded; the second pin is connected with the wireless transceiver through a third capacitor C3; the third pin is connected with a power supply circuit 6; the fourth pin is grounded through a fourth capacitor C4; the fifth pin and the sixth pin are connected with the controller 2; the seventh pin is suspended; and the eighth pin is connected with the working frequency control circuit.
It will be appreciated that the third capacitor C3 and the fourth capacitor C4 act as self-filtering circuits for the radio transceiver component 1. When receiving an instruction sent by a vehicle remote controller through a wireless transceiver connected with the second pin, the wireless transceiver component 1 decodes the instruction, and outputs a decoded signal to the controller 2 by using the fifth pin and the sixth pin as decoded signal output pins.
It should be noted that the controller 2 includes a plurality of pins;
a first pin of the controller 2 is connected with a power supply circuit 6; the second pin is connected with the switch circuit 4; the third pin and the fourth pin are connected with the wireless transceiving component 1; the fifth pin is connected with an infrared sensor 5; the sixth pin and the seventh pin are connected with an alarm 3; the eighth pin is grounded.
In a specific practice, the controller 2 may be previously enabled to perform the learning mode through the switch circuit 4, at which time the unlock key and the lock key on the vehicle remote controller are respectively pressed. The wireless transceiver module 1 receives the two signals, decodes the two signals, and outputs two decoded signals to the controller 2. The controller 2 stores the two decoding signals inside to complete learning, and at this time, the controller 2 exits from the learning mode through the switch circuit 4, which is a conventional technical means for the controller 2 to learn the decoding signals in the prior art and is not described here. After learning is complete, the controller 2 reacts only to the same signals as the two decoded signals stored internally and does not react anything to any other signals.
It should be noted that the alarm 3 may be, but is not limited to, an audible and visual alarm 3.
It can be understood that, in the implementation of the circuit of the vehicle-mounted alarm 3 in the present embodiment, the wireless transceiver module 1 receives the unlocking or locking signal sent by the vehicle remote controller, and then sends the unlocking or locking command signal to the controller 2. The controller 2 enters a dormant state when receiving an unlocking signal, and when receiving a vehicle locking signal and receiving a trigger signal of the infrared sensor 5, the controller proves that the vehicle is locked and a person is in the vehicle at the moment, and then outputs an alarm signal to the alarm 3, so that the alarm 3 gives an alarm.
Preferably, the controller 2 in this embodiment may further enter the sleep state to save power consumption when the trigger signal of the infrared sensor 5 is not received within a set time after the vehicle locking signal is received.
It should be noted that the circuit of the vehicle-mounted alarm 3 further includes: a power supply circuit 6;
the power circuit 6 is respectively connected with the wireless transceiving component 1, the controller 2, the switch circuit 4 and the infrared sensor 5.
It should be noted that the power supply circuit 6 is a 4.5V voltage power supply, in a specific practice, a mobile power supply may be selected, and the power supply may be boosted by a voltage boost board of the mobile power supply.
It should be noted that the circuit of the vehicle-mounted alarm 3 further includes: a voltage stabilizing filter circuit 7;
the voltage stabilizing filter circuit 7 includes: a voltage stabilizer U1;
the power circuit 6 is respectively connected with the wireless transceiving component 1, the controller 2, the switch circuit 4 and the infrared sensor 5 through the voltage stabilizer U1.
The voltage stabilizing filter circuit 7 includes: further comprising: a first capacitor C1 and a second capacitor C2;
the first capacitor C1 and the second capacitor C2 are connected to an output port of the voltage stabilizer U1.
It can be understood that, in this embodiment, the voltage output by the power supply circuit 6 is further subjected to voltage stabilization filtering processing by the voltage stabilizer U1, the first capacitor C1 and the second capacitor C2, so as to ensure the safety and the anti-interference of the circuit.
It should be noted that in an implementable manner in this embodiment, the infrared sensor 5 is disposed above the rear row of the vehicle.
It can be understood that, in general, a person sitting on the front passenger seat cannot be accidentally locked in the vehicle, so that the infrared sensor 5 is disposed above the rear seat of the vehicle in the present embodiment, so that whether the person sitting on the rear seat of the vehicle is accidentally locked in the vehicle is mainly detected.
Example two
A vehicle-mounted article is at least one of a vehicle-mounted storage bag, a vehicle-mounted fragrance or a vehicle-mounted atmosphere lamp, and a vehicle-mounted alarm 3 circuit is mounted in the vehicle-mounted article.
It can be understood that, because the vehicle alarm 3 circuit peripheral component in this embodiment is few, uses extensively, possess independent power supply, and the service life is longer based on the sleep mechanism of oneself, can carry on the vehicle alarm 3 circuit to on-vehicle articles such as on-vehicle storing bag, on-vehicle champignon or on-vehicle atmosphere lamp in this embodiment, need not refit the vehicle and also can be suitable for all motorcycle types, it is simple and convenient to use.
It is understood that the same or similar parts in the above embodiments may be mutually referred to, and the same or similar parts in other embodiments may be referred to for the content which is not described in detail in some embodiments.
