It should be appreciated that the emergency light may be used to guide the evacuation of trapped personnel or to deploy fire rescue operations after the normal lighting ac is turned off in the event of an accident. The alternating current end of the emergency lamp is connected with the mains supply for a long time, and alternating current is monitored in real time through an alternating current detection circuit inside the emergency lamp. When power is cut off, the emergency lamp starts to work and is powered by the battery inside the emergency lamp; when the power is restored, the emergency lamp stops working and simultaneously charges the battery. Emergency lamps in the current market mainly focus on the endurance and reliability of products, and most of the products achieve the purpose of improving battery endurance by using high-performance lamp beads or increasing battery capacity, so that cost is often consumed. Part of emergency lamp products also have increased human body induction function, can light when detecting someone, if not detect the people after the period of time, will extinguish. However, the most important parameter of human body induction is the induction distance, most human body induction distances are about 7-10 meters, and the induction distance can only reach 2-4 meters in consideration of the actual installation position of the emergency lamps, so that the installation distance among a plurality of emergency lamps is required to be very close, more emergency lamps are required to be installed under the condition, the installation cost of the emergency lamps is increased, and the service efficiency of the emergency lamps is reduced.
Accordingly, the present utility model provides an emergency lamp having 433 communication function, comprising:
a human body sensing circuit 30;
an ac input 10 for receiving ac power;
the main control circuit 20 is electrically connected with the alternating current input end 10 and the human body induction circuit 30;
the main control circuit 20 is configured to control the human body sensing circuit 30 to sense a human body and output a sensing signal when detecting that the ac input terminal 10 is disconnected from the ac;

It can be understood that when an accident occurs, the emergency lamp is disconnected from the alternating current, and the internal battery provides working voltage for the emergency lamp, so that the emergency lamp is in a continuously-lighted state. However, because the electric quantity stored in the battery is limited, the electric quantity of the battery is continuously consumed when the emergency lamp is in a continuously-lighted state, and the emergency lamp cannot be lighted until the electric quantity is consumed, namely, a bright road cannot be provided for trapped people for evacuation, so that the service efficiency of the emergency lamp is greatly reduced. In this embodiment, a human body induction circuit 30 is disposed in the emergency lamp, and most of the human body induction circuits 30 are implemented by pyroelectric infrared sensors, and are used for sensing infrared rays emitted by human bodies to identify whether nearby people are active, so that when people pass through the emergency lamp, an induction signal is emitted to trigger the main control circuit 20 to start the emergency lamp, thereby guiding the evacuation of trapped people. However, most of the human body sensing circuits 30 have limited sensing range, and when the human body is in the non-sensing range of the human body sensing circuits 30, the emergency lamp cannot be turned on, which brings inconvenience to the trapped people. This requires the installation of a plurality of emergency lamps, and the installation distance between a plurality of emergency lamps is very near, just can realize lighting simultaneously for a plurality of emergency lamps to provide bright evacuation passageway for stranded crowd, this kind of solution has increased the installation cost of emergency lamps. Aiming at the defects, the communication circuit 40 is arranged 433, and the communication circuit is combined with the human body induction circuit 30 and the main control circuit 20 to work, so that when a person passes through the induction range of the emergency lamp, the human body induction circuit 30 induces infrared rays of the human body and outputs induction signals to the main control circuit 20. The main control circuit 20 receives the sensing signal and simultaneously sends a trigger signal to the 433 communication circuit 40, and the 433 communication circuit 40 sends the trigger signal to the external emergency lamp by using a wireless communication technology. It should be understood that the external emergency lamp is also provided with the 433 communication circuit 40, and the external emergency lamp receives the trigger signal through the 433 communication circuit 40 and triggers the external induction lamp to start working according to the trigger signal, so that the external induction lamp is lighted. Therefore, under the condition of low installation cost, the trigger signal is transmitted to the external emergency lamp through the wireless communication technology of the 433 communication circuit 40, so that a plurality of emergency lamps can work simultaneously, and the service efficiency of the emergency lamps is improved.
In the practical application of the emergency lamp, when the normal illumination alternating current is not cut off, the alternating current is output to a battery in the emergency lamp through the alternating current input end 10 so as to charge the battery; when an accident occurs and normal illumination alternating current is cut off, the main control circuit 20 detects that no alternating current flows through the alternating current input end 10, namely, controls a battery in the emergency lamp to start working and outputs battery voltage so as to supply power for the emergency lamp. In addition, when no ac current is detected at the ac input end 10, the main control circuit 20 also controls the human body sensing circuit 30 to start working, so as to output a sensing signal to the main control circuit 20 when sensing that a person is in a sensing range; the main control circuit 20 outputs a trigger signal to the 433 communication circuit 40 according to the detection of the passing of the person by the sensing signal, and simultaneously controls the 433 communication circuit 40 to transmit the trigger signal to the external emergency lamp, so that the 433 communication circuit 40 in the external emergency lamp receives the trigger signal and triggers the external emergency lamp to start working according to the trigger signal.

Meanwhile, the main control circuit 20 controls the human body sensing circuit 30 to start to work, so that the human body sensing circuit 30 outputs a sensing signal when sensing a human body; the main control circuit 20 outputs a trigger signal to the 433 communication circuit 40 according to the detection of the passing of the person by the sensing signal, and simultaneously the 433 communication circuit 40 sends the trigger signal to the external emergency lamp by using the wireless transmission technology so as to trigger the external emergency lamp to start working. The utility model realizes that a plurality of emergency lamps can work simultaneously under the condition of low installation cost, and improves the service efficiency of the emergency lamps.
In this embodiment, the 433 communication circuit 40 includes:
the receiving end is connected with the output end of the main control circuit 20; the transmitting end is electrically connected with the transmitting end;
the receiving end is used for receiving the trigger signal and outputting the trigger signal to the transmitting end;

In this embodiment, the 433 communication circuit 40 includes a receiving end and a transmitting end, where the receiving end is configured to receive the trigger signal output by the main control circuit 20 and output the trigger signal to the transmitting end; the transmitting end is used for receiving the triggering signal of the receiving end and sending the triggering signal to the external emergency lamp in a wireless transmission mode, so that the receiving end of the communication circuit 40 in the external emergency lamp receives the triggering signal, and the external emergency lamp is triggered to start according to the triggering signal. The wireless transmission technology of the communication circuit 40 of this embodiment 433 realizes that a plurality of emergency lamps can work simultaneously, thereby improving the service efficiency of the emergency lamps.
In this embodiment, the emergency lamp with 433 communication function further includes:
a timer 50 electrically connected to the control terminal of the main control circuit 20;
the main control circuit 20 is further configured to control the timer 50 to start timing for a preset duration when the sensing signal is not received, and control the emergency lamp to stop working when the preset duration is reached.
It will be appreciated that in order to increase the energy saving level of the emergency lamp, when the human body sensing circuit 30 senses no human body for a long time, the battery of the emergency lamp is controlled to stop discharging so that the emergency lamp is in a dormant state. A timer 50 is provided in this embodiment for recording the time that an unmanned person has passed the emergency light. Specifically, when a person passes through the induction range of the emergency lamp, the human body induction circuit 30 induces a human body and outputs an induction signal to the main control circuit 20, so that the main control circuit 20 triggers the battery of the emergency lamp to start working according to the induction signal to supply power to the emergency lamp; when no person passes through the sensing range of the emergency lamp, the human body sensing circuit 30 cannot sense the human body, so that the main control circuit 20 cannot receive the sensing signal, and meanwhile, the main control circuit 20 controls the timer 50 to start timing of a preset time period, for example, controls the timer 50 to start timing of a 2-min time period, and controls the battery to stop discharging when the timing time of the timer 50 reaches 2min, so that the emergency lamp enters a dormant state. The timer 50 is set to control the emergency lamp to enter the sleep state when the human body sensing circuit 30 senses no human body for a long time, so that the phenomenon of continuous power consumption of the battery is prevented, and the energy saving level of the emergency lamp is improved.
In this embodiment, the emergency lamp with 433 communication function further includes:

the main control circuit 20 is configured to control the battery to start to operate when detecting that the ac input terminal 10 is disconnected from the ac, so as to supply power to the lamp body.
It will be appreciated that in a safe situation, the emergency lamp is at rest and ac power is supplied to the battery in the lamp body via the ac input 10 to charge the battery; in the event of an accident, the emergency lamp is in an operating state, the ac power is stopped from being supplied to the battery in the lamp body, and the battery in the lamp body starts to operate to supply operating voltages to the lamp body and other operating circuits, such as the main control circuit 20, the human body sensing circuits 30 and 433, and the communication circuit 40, so that the main control circuit 20, the human body sensing circuits 30 and 433, and the communication circuit 40 maintain an operating state.

It will be appreciated that when the emergency lamp is in the inactive state, external ac power is supplied to the battery of the emergency lamp via the ac input 10 to recharge the battery of the emergency lamp. However, the alternating current cannot be directly input to the battery to charge the battery, so the present embodiment is further provided with the voltage conversion circuit 60.
The voltage conversion circuit 60 may be implemented using an AC-DC conversion circuit and a DC-DC conversion circuit, and in this embodiment, the description will be given taking the voltage conversion circuit 60 as an example of the AC-DC conversion circuit.
