Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, in the antenna control circuit 10 with the emergency lighting function provided in the embodiment of the present application, the antenna control circuit 10 realizes integration of two functions of emergency lighting and television signal reception, so as to meet the multi-directional circuit function requirement of the user; for convenience of explanation, only the parts related to the present embodiment are shown, and detailed as follows:

the antenna control circuit 10 includes: the voltage stabilizing component 101, the standby power component 102, the first switch component 103 and the lamp strip antenna component 104.

The voltage stabilizing component 101 is configured to perform voltage stabilizing processing on the first power supply signal output by the power supply device 20 to obtain a second power supply signal when the power supply device 20 is connected.

Optionally, the power supply device 20 is a battery or a commercial power, the power supply device 20 stores a large capacity of electric energy, and the electric energy can be continuously provided to the antenna control circuit 10 through the power supply device 20, so as to ensure the power supply stability of the antenna control circuit 10; when the voltage stabilizing component 101 is electrically connected to the power supply device 20, the voltage stabilizing component 101 can implement a voltage stabilizing circuit function, and the second power signal output by the voltage stabilizing component 101 has a stable voltage amplitude; therefore, the power supply device 20 belongs to external power, the antenna control circuit 10 in this embodiment can directly access the external power, thereby realizing the power supply reliability of itself and improving the compatibility and stability of the antenna control circuit 10.

The standby power supply unit 102 is connected to the voltage regulator unit 101, and is configured to output a third power supply signal when the power supply device 20 is turned off.

For example, since the standby power supply component 102 is electrically connected to the voltage stabilizing component 101, when the standby power supply component 102 does not receive the second power supply signal, it is determined that the power supply device 20 does not access the voltage stabilizing component 101; when the standby power supply component 102 receives the second power supply signal, it is determined that the power supply device 20 is connected to the voltage stabilizing component 101; therefore, the standby power supply unit 102 in the present embodiment can sensitively detect the on or off state of the voltage device 20.

When the power supply device 20 is abnormally cut off, the antenna control circuit 10 loses external electric energy, and then the third power supply signal output by the standby power supply component 102 is used as emergency electric energy and can continuously supply power to the electronic components through the third power supply signal, so that the safety and reliability of the internal electric energy of the antenna control circuit 10 are guaranteed; therefore, the antenna control circuit 10 in this embodiment can quickly cope with an abnormal power-down event of external electric energy, and the antenna control circuit 10 can be applied to various different industrial technical fields to maintain a normal and stable electric energy function, and has an extremely high practical value.

The first switching element 103 is connected to the voltage regulator element 101 and the standby power supply element 102, and is configured to be turned on or off, and to transmit the second power supply signal or the third power supply signal when turned on.

Optionally, the first switch component 103 is turned on or off according to an on-off control signal, where the on-off control signal includes information of a circuit on-off control requirement of a user, and then the first switch component 103 is turned on or off according to an actual circuit function requirement of the user, so that the antenna control circuit 10 has higher controllability; specifically, when the first switch module 103 is turned on, the first switch module 103 outputs a second power signal or a third power signal, and the electronic component is powered by the second power signal or the third power signal; when the first switch element 103 is turned off, the first switch element 103 cannot output the second power signal or the third power signal; therefore, the present embodiment can control the transmission process of the external electric energy or the emergency electric energy by the on-off state of the first switch component 103, and improves the power supply control efficiency of the antenna control circuit 10.

Illustratively, the first switch assembly 103 includes a contact of a relay, and the power transmission line is controlled to be turned on or off through the contact of the relay, and when a coil of the relay is powered on or powered off, the contact of the relay is turned on or off, so that the on state or the off state of the first switch assembly 103 has high control flexibility and stability, and the power supply control step of the antenna control circuit 10 is simplified.

The light strip antenna assembly 104 is connected to the first switch assembly 103, and is configured to receive the television signal as an antenna element by means of a patch capacitor when receiving the second power signal or the third power signal, and to emit a light source signal when receiving the third power signal.

Specifically, when the first switch component 103 is turned on, the first switch component 103 outputs the second power signal or the third power signal to the light strip antenna assembly 104, the light strip antenna assembly 104 is successfully powered on, and the light strip antenna assembly 104 enters a working state; on the contrary, when the first switch component 103 is turned off, the light strip antenna component 104 cannot access the second power signal and the third power signal, and at this time, the light strip antenna component 104 is in a stop state, and the circuit function cannot be realized; therefore, the electric energy input process of the lamp antenna assembly 104 in the embodiment has high control response precision and speed.

Specifically, when the power supply device 20 is normally connected to the voltage stabilizing component 101, the light strip antenna assembly 104 is powered by external electric energy, and at this time, the light strip antenna assembly 104 is connected to a second power supply signal to realize a power-on function; illustratively, the light strip antenna assembly 104 is connected to the ground television signal base station 30, and the light strip antenna assembly 104 communicates with the ground television signal base station 30, where the ground television signal base station 30 is configured to output television signals, the television signals include various types of audio and video information, and then the light strip antenna assembly 104 may receive complete television signals; when the power supply device 20 is abnormally cut off, the light strip antenna assembly 104 is powered by emergency electric energy, at this time, the standby power supply assembly 102 outputs a third power supply signal to the light strip antenna assembly 104, and the light strip antenna assembly 104 can receive a television signal sent by the ground television signal base station 30 and send a light source signal, so that integration of two functions of television signal receiving and emergency lighting is realized; therefore, the present embodiment, in combination with the standby power supply component 102 and the power supply device 20, can implement the continuous power supply function of the strip antenna assembly 104; the lamp strip antenna assembly 104 can stably receive television signals no matter the power supply device 20 or the standby power supply assembly 102 supplies power, so that the continuity and reliability of the television signals are guaranteed; and when power supply unit 20 appeared and became out of order when the power down, then started standby power supply subassembly 102 and carry out emergency power supply to lamp area antenna module 104, lamp area antenna module 104 can send emergency light source this moment to satisfy user's emergency lighting demand, therefore lamp area antenna module 104 can realize the integration use of these two of television signal reception and emergency lighting.

In this embodiment, after the light strip antenna assembly 104 is successfully powered on, the light strip antenna assembly 104 may always receive a television signal sent by the ground television signal base station 30, so as to maintain the reliability of television signal reception; when emergency electric power supply is performed through the standby power pack 102, the light source signal emitted by the lamp strip antenna assembly 104 can meet the lighting requirement, and for example, the lamp strip antenna assembly 104 emits the light source signal with preset light intensity and preset color, so that good visual experience is brought to a user; specifically, the lamp strip antenna assembly 104 realizes the communication of oscillators between the LED circuits by adopting a patch capacitor cross-over connection manner, and completes a real-time television signal receiving function; exemplarily, after the light strip antenna assembly 104 receives a television signal, the television signal is amplified and the like to obtain a television signal of a corresponding level, and finally the television signal is input to a terminal device such as a television for video playing; the capacitor bridging mode can ensure the direct current isolation of the lamp strip antenna assembly 104 during work, and the high-frequency alternating current path of television signals can ensure that the antenna receiving performance is not influenced when the lamp strip antenna assembly 104 is electrified to emit light; therefore, the present embodiment realizes the multiplexing of the circuit function through the light strip antenna assembly 104, and simplifies the design of the circuit structure.

In the structural schematic of the antenna control circuit 10 shown in fig. 1, the lamp antenna assembly 104 is powered up by the electric energy output by the power supply device 20, so that the electric energy compatibility of the antenna control circuit 10 is guaranteed; when the power supply device 20 has an abnormal power failure event, the electric energy output by the standby power supply component 102 is used as emergency electric energy, so that the electric energy stability of the lamp strip antenna assembly 104 in the process of receiving television signals is improved; when the lamp strip antenna assembly 104 is powered on by emergency electric energy, the lamp strip antenna assembly 104 can realize two functions of illumination and signal reception, so that the effect of integrating two circuit functions is achieved, great convenience is brought to the use of a user, the antenna control circuit 10 has a more integrated circuit structure, the occupied space volume is smaller, the operation is simple and convenient, and the illumination cost and the television signal reception cost are lower; therefore, the problems that in the prior art, the function of the electronic equipment is single, great inconvenience is brought to users, the occupied size of the electronic equipment is large, the application cost of the electronic equipment is high, and the power supply safety of the electronic equipment is low are effectively solved.

Illustratively, the voltage stabilizing module 101 outputs the second power signal to the charging component 1021, and the voltage stabilizing module 101 performs a voltage reduction or voltage increase process on the charging signal, so that the charging signal output by the charging component 1021 maintains a more stable amplitude, and a compatible charging function can be realized for the electronic component based on the charging signal; therefore, the charging unit 1021 in this embodiment can realize the function of efficient power transmission and conversion, and the antenna control circuit 10 has higher power stability.

The battery part 1022 is connected between the charging part 1021 and the first switch component 103, and is configured to generate a third power signal by charging according to the charging signal when receiving the charging signal or discharging when not receiving the charging signal.

Wherein the battery part 1022 has an electric energy storage function, when the charging part 1021 outputs a charging signal to the battery part 1022, it means that the power supply device 20 accesses the voltage stabilizing assembly 101, and the battery part 1022 is charged by the charging signal; meanwhile, when the battery component 1022 does not receive the charging signal, it indicates that the power supply device 20 is not connected to the regulated voltage component 101, and the battery component 1022 releases electric energy, so that the third power supply signal output by the battery component 1022 realizes more stable emergency electric energy supply; therefore, the battery part 1022 can realize flexible charging and discharging functions to realize the effect of internal emergency power guarantee of the antenna control circuit 10.

Specifically, when the power supply device 20 is not connected to the voltage stabilizing component 101, the battery component 1022 discharges to generate a third power supply signal, and the first switch component 103 is further configured to output the third power supply signal to the light strip antenna assembly 104 when being turned on, so as to perform emergency power supply on the light strip antenna assembly 104.

In this embodiment, the transmission process of the third power signal can be flexibly controlled by the first switch component 103, when the power device 20 is abnormally shut off, the standby power component 102 generates electric energy by discharging, and the standby power component 102 outputs the third power signal to the light strip antenna assembly 104 to realize the emergency power supply function, so the electric energy stored by the battery component 1022 is utilized in this embodiment, when the power device 30 is abnormally shut off, the electric energy discharged by the light strip antenna assembly 104 through the battery component 1022 can still be continuously and stably accessed, the power-on efficiency and the working efficiency of the light strip antenna assembly 104 are improved, and the standby battery component 102 in this embodiment has relatively compatible emergency power supply performance.
