500KW short-wave transmitter logic control method and system

Abstract

The invention relates to a 500KW short-wave transmitter logic control method and a system. The method includes that a state machine with a red light wire state, a black light wire state, a shutdown delay state and a standby state; a logic controller receives an externally input control command, different operations are carried out according to judgment on the control command and current state of the state machine, such as carrying out from the standby operation to the black light wire state operation, from the red light wire state to the black light wire state operation, from the black light wire state to the red light wire state operation or from the black wire state operation to the shutdown delay operation, and the state machine conducts state skip; when the state machine enters a shutdown delay time section after the shutdown delay state, if the logic controller does not receive the control command, operation from shutdown delay to standby is carried out. The 500KW short-wave transmitter logic control method and the system achieve automatic control and remote control of a 500KW short wave transmitter, greatly relieves workload and working difficult of operators, and enables the 500KW short wave transmitter to have the advantages of being stable in performance, simple in structure, low in cost, easy to maintain and the like.

Description

technical field [0001] The present invention relates to high-power short-wave transmission technology, in particular to a logic control method and system for a 500KW short-wave transmitter. Background technique [0002] In the field of current short-wave transmitter technology, only a few manufacturers in China can produce short-wave transmitters with a power of 50KW, 100KW and 150KW, and only a few foreign manufacturers are producing short-wave transmitters with a power of 500KW. Such as Continental Corporation in the United States and TALES Corporation in Switzerland. [0003] For domestic users, the imported 500KW short-wave transmitter is not only expensive to introduce, but also the follow-up maintenance costs are also very staggering. It is very necessary for domestic users to independently develop a 500KW short-wave transmitter. [0004] The inventor finds in the process of realizing the present invention: the logic controller in the shortwave transmitter is one of t...

Problems solved by technology

[0004] The inventor finds in the process of realizing the present invention: the logic controller in the shortwave transmitter is one of the key components of the shortwave transmitter, and the logic controller is just like the brain of the shortwave transmitter to direct other parts in the shortwave transmitter to operate in harmony, However, since the transmitting principle of the 500KW short-wave transmitter is quite different from that of other power short-wave transmitters, the logic controller in other power short-wave transmitters cannot be adapted to the 500KW short-wave transmitter through upgrading and transformation.
