[0002] It is known that the transmitter is the core component of some equipment, and some devices inside the transmitter are easy to be damaged and very expensive; therefore, the ability training of the operator mainly relies on the opportunity of daily maintenance, and the training of the emergency repair personnel can only be carried out in the actual installation learning when the equipment fails. This is far from enough to cultivate the maintenance ability of the personnel. With the increasing heavy work tasks, the transmitter failures are also increasingly frequent, and the transmitter failures cannot be timely eliminated, which affects the performance of the equipment and even damages other important devices of the equipment. In order to cultivate the compound talents with one specialty and multiple positions and one person with multiple positions, according to the current equipment situation, it is urgently needed to explore new training mechanism and training method.

[0003] In the prior art, there is no detection teaching platform for the transmitter control system to improve the maintenance support ability, improve the ability and quality of the professional personnel, and prolong the service life of the equipment. SUMMARY

[0008] The conditioning module is used to condition the 24V voltage from the power module under the control of the protection module, send the obtained conditioning signal to the total detection meter, and condition the 9V voltage from the power module and send it to the external load.

[0009] The protection module is used to transmit the 6.3V output by the power module to the indicator light module and transmit the 24V output by the power module to the conditioning module through protection control.

[0010] A total detection meter is used to detect whether the voltage or current of the conditioning signal sent by the conditioning module is normal according to the control of the self-dial.

[0011] In summary, the detection teaching platform of the transmitter control system as an analog training device, under the control of the protection module, the voltage is reduced by the power module, and after the treatment such as voltage division and current division by the conditioning module, each conditioning signal is transmitted to the total detection meter through the line.

At this time, since the third power supply, the fourth power supply, and the fifth power supply are not in working state, the third line package J30 of the third relay, the fourth line package J40 of the fourth relay, the fifth line package J50 of the fifth relay, the sixth line package J60 of the sixth relay, and the seventh line package J70 of the seventh relay are all not powered, the first normally closed contact J31, the second normally closed contact J41, the fourth normally closed contact J63, the fifth normally closed contact J71, the third normally closed contact J53, and the sixth normally closed contact J61 are all closed, the fourth normally open contact J51, the fifth normally open contact J52, and the seventh normally open contact J62 are all open: on the one hand, the filament drop indicator light DSJ is on, the high voltage drop indicator light GYJ is on, and the magnetron full filament works; on the other hand, when the high voltage on switch GT (pressing the high voltage on switch GT) and the high voltage off switch GD are both in the closed state, since the cabinet door of the detection teaching platform of the transmitter control system is closed, the eighth line package J80 in the eighth relay is powered, the eighth normally open contact J81 and the ninth normally open contact J82 are both closed: the eighth normally open contact J81 and the ninth normally open contact J82 are both closed, the ninth line package J90 of the ninth relay is powered; the passive switch BD is closed, the tenth line package J100 of the tenth relay is also powered, the tenth normally open contact J91, the eleventh normally open contact J92, the twelfth normally open contact J101, and the thirteenth normally open contact J102 are all closed, the third 24V power supply unit 13, the fourth 24V power supply unit 14, and the fifth 24V power supply unit 15 start to work. When the third 24V power supply unit 13, the fourth 24V power supply unit 14, and the fifth 24V power supply unit 15 are working normally, the third relay, the fourth relay, and the seventh relay as overload relays are all not actuated, the first normally closed contact J31, the second normally closed contact J41, and the fifth normally closed contact J71 are all closed; the fifth relay and the sixth relay as low-load relays are actuated, the fourth normally open contact J51 and the fifth normally open contact J52 are both closed, the third normally closed contact J53 is open, and the eighth normally open contact J81 and the fifth normally open contact J52 realize the self-protection of the eighth line package J80 being powered, that is, even if the high voltage on switch GT is opened (the high voltage on switch GT is released), it does not affect the state of the eighth line package J80 being powered; at the same time, the high voltage on indicator light GYT is on, and the high voltage drop indicator light GYJ is off; the fourth normally closed contact J63 is open, the seventh normally open contact J62 is closed, and the magnetron half filament works.When the passive switch BD is opened, the tenth wire bundle J100 in the tenth relay cannot be electrified, the twelfth normally open contact J101 and the thirteenth normally open contact J102 are both opened, and the fifth 24V power supply unit 15 stops working because it cannot be connected to the mains 220V. In addition, when the high-voltage switch GD is manually pressed, the high-voltage switch GD is opened, the eighth wire bundle J80, the ninth wire bundle J90 and the tenth wire bundle J100 cannot be electrified, and the third 24V power supply unit 13, the fourth 24V power supply unit 14 and the fifth 24V power supply unit 15 all stop working because they cannot be connected to the mains 220V. In practical application, as long as the mains and the second transformer T2 are not faulty, the power supply indicator lamp DY is always lit.

[0058] In practical application, the first 24V power supply unit 11 provides a cutoff voltage for the external pre-tuner YTQ, the second 24V power supply unit 12 provides a gate negative bias for the external modulator TZQ, the third 24V power supply unit 13 and the fourth 24V power supply unit 14 provide a curtain gate positive voltage for the external modulator TZQ, and the fifth 24V power supply unit 15 provides a working voltage for the magnetron CKQ. The high-voltage reduction indicator lamp GYJ and the high-voltage pass indicator lamp GYT indicate the working states of the external loads corresponding to the third 24V power supply unit, the fourth 24V power supply unit and the fifth 24V power supply unit. The filament reduction indicator lamp DSJ indicates that the external magnetron CKQ works in a full filament state or a half filament state. The bias voltage indicator lamp PY indicates the working state of the gate negative bias of the external modulator TZQ. The working states of the external loads and the working principle are not the specific content of the patent, and therefore are not described here.

[0059] In practical application, the mains 220V is also connected to the external load hair dryer CFJ serving the actual transmitter working system.
