本实用新型提出一种接收装置的检测电路。The utility model provides a detection circuit of a receiving device.

在本实用新型一实施例中,如图1所示,该接收装置的检测电路包括检测提示模块20、衰减红外发射模块10和供电模块30;In an embodiment of the present invention, as shown in FIG. 1 , the detection circuit of the receiving device includes a detection prompt module 20 , an attenuated infrared emission module 10 and a power supply module 30 ;

所述检测提示模块20和衰减红外发射模块10的电源输入端与所述供电模块30的电源输出端相连;The power input terminals of the detection prompt module 20 and the attenuation infrared emission module 10 are connected to the power output terminal of the power supply module 30;

所述衰减红外发射模块10,用于向所述接收装置发送衰减后的红外IR信号,之所以要对红外IR信号进行衰减,是因为在实际操作中,接收装置和发射器的距离一般较远,而在实际测试过程中,如若为了模拟实际的接发距离而将检测装置按照实际的接发距离进行设计的话,显然很不切实际,所以为了既能实现检测装置的便捷性,又能避免接发距离过短存在的误判性,本实用新型对发送的红外IR信号进行衰减操作,实现接发距离的增加,例如检测装置与接收装置的接发距离设置在30cm,但因为衰减红外发射模块10的存在,使得实际的接发距离可达到8m;The attenuated infrared transmitting module 10 is used to send the attenuated infrared IR signal to the receiving device. The reason for attenuating the infrared IR signal is because in actual operation, the distance between the receiving device and the transmitter is generally long. In the actual test process, it is obviously unrealistic to design the detection device according to the actual transmission distance in order to simulate the actual transmission distance. Therefore, in order to realize the convenience of the detection device and avoid the There is a misjudgment that the sending and receiving distance is too short. The utility model performs an attenuation operation on the transmitted infrared IR signal to realize the increase of the sending and receiving distance. The existence of the module 10 makes the actual sending and receiving distance up to 8m;

The collector of the first transistor Q1 is connected to The cathode of the infrared emitting diode D1 and the anode of the infrared emitting diode D1 are connected in series with the first capacitor C1 and the second capacitor C2;

所述第一三极管Q1的发射极接地。The emitter of the first transistor Q1 is grounded.

进一步的,所述衰减红外发射模块10还包括控制处理芯片U1和晶体振荡器X1;Further, the attenuated infrared emission module 10 further includes a control processing chip U1 and a crystal oscillator X1;

At this time, the control and processing chip U1 officially enters the working state.

控制处理芯片U1在进入工作状态后,当8脚和23脚连接闭合时,会出发12脚输出一个指令,进而向衰减电阻R1输出高电平,高电平经过衰减电阻R1后到达第一三极管Q1的基极,使得第一三极管Q1饱和导通。After the control processing chip U1 enters the working state, when the 8-pin and 23-pin connection is closed, it will send out a 12-pin output command, and then output a high level to the attenuation resistor R1, and the high level will reach the first three after passing through the attenuation resistor R1. The base of the transistor Q1 makes the first transistor Q1 saturate and conduct.

而由因为电池BAT输出的电源除了经由第一电容C1和第二电容C2后输出至控制处理芯片U1之外,该电源还经由第一电容C1和第二电容C2输出至红外发射二极管D1和第一三极管Q1的集电极,因此此时的电源形成一个回路,使得红外发射二极管D1发出衰减后的红外IR信号。In addition to outputting the power output from the battery BAT to the control processing chip U1 via the first capacitor C1 and the second capacitor C2, the power is also output to the infrared emitting diode D1 and the first capacitor C2 via the first capacitor C1 and the second capacitor C2.

所述第二电阻R3的一端与所述第二三极管Q2的发射极相连,所述第二电阻R3的另一端接在所述插座CN1的VCC脚和所述电源之间,第二电阻R3同样为限流电阻,避免+V端输出的电源电压过大,从而对检测提示模块20的电路造成的损坏的现象。One end of the second resistor R3 is connected to the emitter of the second transistor Q2, the other end of the second resistor R3 is connected between the VCC pin of the socket CN1 and the power supply, the second resistor R3 is also a current limiting resistor to avoid the phenomenon that the power supply voltage output by the +V terminal is too large, thereby causing damage to the circuit of the detection and prompting module 20 .

在本实施例中,如图2中的检测提示模块20所示,该模块中的插座CN1与接收装置的插座中的脚对应连接,即两端插座的GND脚接GND脚,VCC脚接VCC脚,其中检测提示模块20中的PUT脚与接收装置中的OUT脚相连,用于接收接收装置发出的电平信号。In this embodiment, as shown in the detection and prompting module 20 in FIG. 2 , the socket CN1 in the module is connected to the pins in the socket of the receiving device correspondingly, that is, the GND pins of the sockets at both ends are connected to the GND pins, and the VCC pins are connected to the VCC pins. pin, wherein the PUT pin in the detection prompt module 20 is connected with the OUT pin in the receiving device, and is used for receiving the level signal sent by the receiving device.

当检测提示模块20的PUT脚接收到接收装置中的OUT脚输出的低电平时,低电平经由稳压二极管D2,此时的第一电阻R2不工作,第二三极管Q2的基极为低电平,因此此时第二三极管Q2的基极为低电压。而+V端输出的电源经过第三电阻后到达第二三极管Q2的发射极,因此此时的发射极为高电压,因为上述说明了第二三极管Q2的基极为低电压,故第二三极管Q2的发射极和集电极直接导通,+V端输出的电源流入发光二极管D3中,发光二极管D3在得到第二三极管Q2输出的电压后进行亮灯操作,以提示操作人员接收装置能够正常运行。When the PUT pin of the detection prompt module 20 receives the low level output from the OUT pin in the receiving device, the low level passes through the zener diode D2, the first resistor R2 does not work at this time, and the base of the second transistor Q2 is Low level, so the base of the second transistor Q2 is at a low voltage at this time. The power output from the +V terminal reaches the emitter of the second transistor Q2 after passing through the third resistor, so the emitter at this time is extremely high voltage. The emitter and collector of the second triode Q2 are directly turned on, and the power output from the +V terminal flows into the light-emitting diode D3. The light-emitting diode D3 lights up after obtaining the voltage output by the second triode Q2 to indicate the operation. The personnel receiving device can function normally.

当检测提示模块20的PUT脚接收到接收装置中的OUT脚输出的为高电平时,此时的高电平会击穿稳压二极管D2,为了避免高电平对检测提示模块20的电路造成损坏,此时的第一电阻R2开始工作,对高电平进行限流,限流后的高电平流入第二三极管Q2的基极中,此时的基极为高电压。而+V端输出的电源依旧会经由第三电阻后到达第二三极管Q2的发射极,进而发射极为高电压,那么此时的发射极和集电极就会断开,使得+V端的供电无法经由第三电阻和第二三极管Q2达到发光二极管D3,故此时的发光二极管D3无法进行亮灯操作,操作人员在观察到检测装置没有进行亮灯操作时,就能得到该接收装置存在运行异常的信息。When the PUT pin of the detection prompt module 20 receives a high level output from the OUT pin in the receiving device, the high level at this time will break down the Zener diode D2, in order to avoid the high level causing the circuit of the detection prompt module 20 to be affected If it is damaged, the first resistor R2 starts to work at this time to limit the current of the high level, and the high level after the current limitation flows into the base of the second transistor Q2, and the base at this time is a high voltage. The power output from the +V terminal will still reach the emitter of the second transistor Q2 through the third resistor, and then the emitter is extremely high voltage, then the emitter and collector will be disconnected at this time, so that the power supply of the +V terminal The light-emitting diode D3 cannot be reached through the third resistor and the second transistor Q2, so the light-emitting diode D3 cannot be turned on at this time. When the operator observes that the detection device is not turned on, he can know that the receiving device exists. Information about abnormal operation.
