and a second board connected to the first board through a general purpose interface and operated by a general purpose PC operating system, wherein construction machine information acquired from a state acquisition unit inside a construction machine is input to the first board. ## Claims ### Claim 1 A construction machine controller comprising: a first board performing control processing limited to a necessary function of an operation of a construction machine by a construction machine embedded operating system, the control processing requiring real-time performance; a second board connected to the first board through a general purpose interface and operated by a general purpose personal computer (PC) operating system, the second board performing another control processing that does not require real-time performance and that is not limited to the necessary function of the operation of the construction machine performed by the first board; a first controller of the first board configured to perform power monitoring of the first board and system monitoring of the first board in response to an activation of the construction machine, wherein the first controller further configured to perform activation processing of the first board in response to a signal that the power monitoring and the system monitoring of the first board are normal; and a second controller of the second board configured to perform power monitoring of the second board and system monitoring of the second board in response to the activation processing of the first board, wherein the second controller further configured to perform activation processing of the second board in response to a signal that the power monitoring and the system monitoring of the second board are normal, wherein construction machine information acquired from a state acquisition unit inside the construction machine is inputted to the first board. ### Claim 2 (depends on 1) The construction machine controller according to claim 1, wherein each of the first board and the second board includes an internal power circuit converting source voltage supplied from a power source of the construction machine into a desired voltage. ### Claim 3 (depends on 1) The construction machine controller according to claim 1, wherein the first board includes a storage unit, temporarily stores the construction machine information acquired during the activation processing of the second board in the storage unit and transfers the construction machine information temporarily stored in the storage unit to the second board after the activation processing of the second board. ### Claim 4 (depends on 1) The construction machine controller according to claim 1, wherein the first board and the second board are housed inside a same housing. ### Claim 5 (depends on 1) The construction machine controller according to claim 1, further comprising an extended function processing board connected to the first board or the second board, wherein the extended function processing board performs predetermined processing. ### Claim 6 A construction machine controller comprising: a first board performing control processing limited to a necessary function of an operation of a construction machine by a construction machine embedded operating system, the control processing requiring real-time performance; a second board connected to the first board through a general purpose interface and operated by a general purpose personal computer (PC) operating system, the second board performing another control processing that does not require real-time performance and that is not limited to the necessary function of the operation of the construction machine performed by the first board; a first controller of the first board configured to perform power monitoring of the first board and system monitoring of the first board in response to an activation of the construction machine, wherein the first controller further configured to perform activation processing of the first board in response to a signal that the power monitoring and the system monitoring of the first board are normal; and a second controller of the second board configured to perform power monitoring of the second board and system monitoring of the second board in response to the activation processing of the first board, wherein the second controller further configured to perform activation processing of the second board in response to a signal that the power monitoring and the system monitoring of the second board are normal, wherein the first board and the second board are housed inside a same housing, each of the first board and the second board includes an internal power circuit converting source voltage supplied from a power source of the construction machine into a desired voltage, construction machine information acquired from a state acquisition unit inside the construction machine is inputted to the first board, and the first board includes a storage unit, temporarily stores the construction machine information acquired during the activation processing of the second board in the storage unit and transfers the construction machine information temporarily stored in the storage unit to the second board after the activation processing of the second board.
