Detailed Description
The on-board alarm system for realizing bidirectional communication signal transmission by two core wires of the invention is shown in figure 1, and is the same as the prior art, the on-board alarm system comprises a direct current power supply E with 24V output, AN alarm bell ARB1 which is positioned on a first ground and has a rated voltage of 6V and AN alarm key AN2 which is positioned on a second ground are connected in series between the positive electrode and the negative electrode of the direct current power supply E, 18 forward diodes D1 which are connected in series with the alarm bell ARB1, the anode of each forward diode D1 is connected with the positive electrode of the direct current power supply E, each forward diode D1 is a silicon tube with a voltage of 0.7V, so the series voltage of the 18 forward diodes D1 which are connected in series is 12.6V, and AN alarm key AN1 which is connected in series and AN indicator lamp DL1 with a rated voltage of 12V are connected in parallel with a series branch circuit of the alarm bell ARB1 and the forward diode D1; AN indicator light DL2 with the rated voltage of 12V is connected in series with the alarm key AN2, AN alarm bell ARB2 with the rated voltage of 6V and a plurality of forward diodes D2 which are connected in series are connected in parallel with a series branch of the alarm key AN2 and the indicator light DL2, the cathode of each forward diode D2 is connected with the cathode of a direct current power supply E, each forward diode D2 is a silicon tube with the voltage of 0.7V, so that the series voltage of the 18 forward diodes D2 which are connected in series is 12.6V, and the internal resistances of the alarm bell ARB1, the alarm bell ARB2, the indicator light DL1 and the indicator light DL2 are equal.
The working principle is as follows:
1. normal state (without alarm)
The alarm keys AN1 and AN2 are both off, at this time, the sum of the serial connection voltages of the 18 forward diodes D1 connected in series and the 18 forward diodes D2 connected in series is 25.2V, which is greater than the output voltage 24V of the direct current power supply E, so that the forward diodes D1 and the forward diodes D2 are both in a cut-off state, the alarm bells ARB1 and ARB2 do not sound for alarm, and the indicator lamps DL1 and DL2 are not bright;
2. two-way alarm
If the alarm key AN1 is closed, the alarm key AN2 is disconnected, the forward diode D2 is connected in series with a voltage of 12.6V and is smaller than the DC power supply 24V to be conducted, the forward diode D1 is cut off, and the positive output of the DC power supply E is transmitted to the negative electrode of the DC power supply E through the alarm key AN1, the indicator lamp DL1, the alarm bell ARB2 and the forward diode D2. At this time, the voltage borne by alarm bell ARB2 and indicator light DL1 is (24V-12.6V)/2 =5.7V, and is close to the voltage (6V) of alarm bell ARB2, so alarm bell ARB2 sounds an alarm normally, and the voltage of 5.7V is about half of the rated voltage 12V of indicator light DL1, so the actual power of indicator light DL1 is about 1/4, and only weak light or no light is emitted.
If the alarm key AN2 is closed, the alarm key AN1 is disconnected, the forward diode D1 is connected in series with a voltage of 12.6V and is smaller than the DC power supply 24V to be conducted, the forward diode D2 is cut off, and the positive output of the DC power supply E is transmitted to the negative electrode of the DC power supply E through the forward diode D1, the alarm bell ARB1, the indicator light DL2 and the alarm key AN 2. At this time, the voltage borne by alarm bell ARB1 and indicator light DL2 is (24V-12.6V)/2 =5.7V, and is close to the voltage (6V) of alarm bell ARB1, so alarm bell ARB1 sounds an alarm normally, and the voltage of 5.7V is about half of the rated voltage 12V of indicator light DL2, so the actual power of indicator light DL2 is about 1/4, and only weak light or no light is emitted.
If the alarm button AN1 and the alarm button AN2 are both closed, the sum of the series voltages of the 18 series forward diodes D1 and the 18 series forward diodes D2 is 25.2V, which is greater than the output voltage 24V of the dc power supply E, so that the forward diodes D1 and D2 are both in the cut-off state. The positive pole output of the direct current power supply E is transmitted to the negative pole of the direct current power supply E through AN alarm key AN1, AN indicator lamp DL1, AN indicator lamp DL2 and AN alarm key AN2, AN alarm bell ARB1 and AN alarm bell ARB2 cannot be powered, so that no sound alarm is given, and the voltage of the indicator lamp DL1, the indicator lamp DL2 and the indicator lamp are 24V/2=12V at the moment, so that the direct current power supply E can normally emit light and can be used as AN alarm signal.
