Abstract
The invention discloses a processor for identifying no passenger at an elevator floor. The processor is characterized by comprising a 12V DC power source, a microwave sensing and detection circuit, and a monostable time delay and high level output circuit; in the microwave sensing and detection circuit, the model number of a microwave sensing controller IC1 adopted is TX982; in the monostable time delay and high level output circuit, the model number of a time base circuit IC2 is NE555. The microwave sensing controller IC1 is mounted on an opposite side to an elevator entrance/exit or on a ceiling; when a passenger waits for taking the elevator, after the microwave sensing controller senses a microwave signal radiated by the passenger, the elevator is enabled to run in a normal state; when no passenger takes the elevator or the last one passenger leaves the elevator, the elevator immediately cancels commands emitted by some floors and automatically stops or adopts such a cross-floor jumping running mode; as a result, the purposes of improving the running efficiency of the elevator, and also reducing energy consumption and meaningless mechanical wear of the elevator, and so on can be achieved.
Description
Technical field
The invention belongs to electronic auto-control technology field, relate to the unmanned boarding recognition processor of a kind of cage lifter floor.
Background technology
At present, elevator all used by overwhelming majority residential quarters, city building, and by the in situ measurement to common several elevator, every portion elevator motor power is 4 ~ 6KW.Every day calculates with running in 3 hours, and in most of the cases, it is many below 1/3 that elevator runs rated passenger capacity, every portion elevator every day without passenger's no-load run time cumulation close to 1 hour.If by elevator operating mode by no-load run every day, normally run when having changed people's boarding into, without stopping transport during passenger's boarding or jumping over operation across station, just can realize improving elevator operating efficiency, reduce the life-span object of energy consumption and the use of increase elevator.
Practice shows: the opposite or the sky that microwave induction controller are arranged on elevator doorway are taken, when microwave induction controller has sensed passenger in region during awaiting elevator, sense the microwave signal of passenger's radiation at microwave induction controller after, through electronic circuit to after microwave signal process, elevator can be made to keep normal condition to run, when leaving elevator without passenger's boarding or last passenger, the instruction that some floor of elevator immediate cancel sends, automatically take stop transport or jump over operation scheme across station, realize improving elevator operating efficiency, both energy resource consumption was reduced, reduce the objects such as the meaningless mechanical wear of elevator.
Below describe that the unmanned boarding recognition processor of cage lifter floor of the present invention is involved necessary in implementation process, guardian technique content in detail.
Summary of the invention
Goal of the invention and beneficial effect: practice shows: the opposite or the sky that microwave induction controller are arranged on elevator doorway are taken, when microwave induction controller has sensed passenger in region during awaiting elevator, sense the microwave signal of passenger's radiation at microwave induction controller after, through electronic circuit to after microwave signal process, elevator can be made to keep normal condition to run, when leaving elevator without passenger's boarding or last passenger, the instruction that some floor of elevator immediate cancel sends, automatically take stop transport or jump over operation scheme across station, realize improving elevator operating efficiency, both energy resource consumption was reduced, reduce the objects such as the meaningless mechanical wear of elevator.
Circuit working principle: the unmanned boarding recognition processor of cage lifter floor is worked by 12V direct-current power supply microwave induction controller IC1 (TX982) and time base circuit IC2.It sets up microwave electric field in the gangway scope of elevator, when microwave antenna has detected passenger's awaiting elevator in guarded region, then microwave electric field can produce reflection echo, faint frequency-shift signaling is gone out through electronic circuit mixing post-detection, this signal is through the micro controller system process of microwave induction controller IC1 inside, again by the triode ON 8 seconds of inside, fallen by the 2nd pin output low level of the microwave induction controller IC1 charge discharging resisting be enough to timing capacitor C1 of holding time.Form monostable time delay circuit by time base circuit IC2, when the 2nd pin of base IC circuit 2 is lower than 1/3 direct current power source voltage at that time, the 3rd pin of time base circuit IC2 exports high level, makes elevator keep normal and runs;
Time delay circuit is formed, delay time about 9 second by resistance R1 and timing capacitor C1.Because delay time sets shorter, if the gangway of elevator has passenger's awaiting elevator successively, microwave induction controller IC1 will trigger single stabilization delay circuit work repeatedly, make the 3rd pin of time base circuit IC2 export high level incessantly by resistance R3, and this high level signal is carried the corresponding port of each portion elevator CPU.
When floor, nobody waits boarding, microwave antenna can't detect passenger's awaiting elevator in region, then microwave electric field can not produce reflection echo, then the 2nd pin of microwave induction controller IC1 exports high level, the 3rd pin then output low level of time base circuit IC2, and it can cancel the issued boarding instruction of this floor automatically, elevator is made automatically to skip this floor, and elevator directly runs to the floor sending boarding instruction, reduce the waiting time of other floors passenger, effectively improve the service efficiency of elevator.
