The present invention provides a circuit control system of a distance type automatic gamma diagnostic machine. The circuit control system takes an ARM processor stm32f405 as a core to control the peripheral of the whole system, a command emitted by a handset is received by a wireless communication module or a 422 communication module and is processed through the ARM processor stm32f405, and then the motion is transmitted to the motor control module, the motor control module controls rotation of the motor to achieve source taking and receiving of the automatic gamma diagnostic machine to complete automatic control of the gamma diagnostic machine so as to improve the working efficiency and ensure the safety of the operator himself, a PGS module and a PGRS module are further added to understand the positions of the gamma machine and the source through real-time monitoring of a location module so as to provide a certain guarantee for the safety of the gamma diagnostic machine and the radiation source and meet the requirement criterions for strict control of the source by our country, and the wireless and wired signal transmission modes allow the automatic gamma diagnostic machine to besuitable for various complex work environments, and the gamma diagnostic machine can be applied in a clear place and a dense row of tubes.
