The invention provides a turnout driving and collecting circuit device of a six-wire system direct-current switch machine. The turnout driving and collecting circuit device comprises an external interface circuit, a driving circuit, a two-out-of-two CPU module, a power supply circuit and a representation collecting circuit. The representation collecting circuit comprises a constant and reverse meter collecting circuit, a representation voltage collecting circuit and a representation transformer. The driving circuit comprises a solid-state relay, a monostable relay and a Hall sensor and is used for controlling the operation of the switch machine; the external interface circuit comprises a CAN bus communication interface and a 485 bus communication interface and is used for connecting the two-out-of-two CPU module with an interlocking host and a detector. The turnout direct-current voltage acquisition circuit of the driving switch machine is added, so that the working current of the turnout is monitored in real time; according to the switch machine turnout indication acquisition circuit, an optocoupler is adopted to replace a polarity relay to acquire a turnout indication loop, the optocoupler is a common component and has the advantages of being low in price, small in size, simple in circuit and the like, and the switch machine turnout indication voltage acquisition circuit is additionally arranged to monitor indication voltage in real time.
