The specific embodiment

Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.

Shown in accompanying drawing 1, a kind of apparatus for controlling elevator with emergency management and rescue function comprises elevator integrated controller, car load sensor and elevator motor; Said apparatus for controlling elevator with emergency management and rescue function also comprises emergency source of electrical power module, power supply switching contactor; The mouth of emergency source of electrical power module is electrically connected with the power input of elevator integrated controller through the power supply switching contactor; The power output end of elevator integrated controller is electrically connected with the power input of elevator motor, and the emergency source of electrical power module is connected with the car load sensor electrical simultaneously.Said elevator integrated controller model is LB90G; Said emergency source of electrical power module is the ups power module; The model of ups power module is EBD-700; Said power supply switching contactor is a KMS type power supply switching contactor; The R of LB90G elevator integrated controller, S, three power inleting terminals of T link to each other with three phase lines of 380V civil power, and wherein R links to each other with two power output ends of ON and OL of ups power module respectively with the commutation circuit of S end through KMS power supply switching contactor, and the ON end of ups power module links to each other with the COM7 end with the Y12 end of LB90G elevator integrated controller through power change-over switch with the OL end; The COM terminal of ups power module links to each other with the mouth of car load sensor; The COM terminal of ups power module links to each other with the COM end of LB90G elevator integrated controller simultaneously; The X1 terminal of ups power module links to each other with the input end of car load sensor; The UP terminal of ups power module links to each other with the REV end of LB90G elevator integrated controller, and the DN terminal of ups power module links to each other with the FWD end of LB90G elevator integrated controller.Said apparatus for controlling elevator with emergency management and rescue function also comprises speech prompting system and loud speaker; Two input ends of speech prompting system link to each other with the J1 interface of elevator integrated controller LB90G, and two mouths of speech prompting system link to each other with two input ends of loud speaker.Said speech prompting system model is: LVS-6 elevator speech prompting system.During practical implementation when elevator unloaded up or heavily loaded when descending; Elevator motor is in the state of generating; So also need the PB of LB90G elevator integrated controller end and+connect a power consumption resistance ZR between the end, prevent that DC bus-bar voltage is too high in the integrated controller.
