Description
Technical field
The present invention relates to elevator control technology, in particular to elevator safety system of a kind of foundation on bus foundation.
Background technique
A kind of elevator safety system is proposed in patent document CN 103079981B, by controller and hoistway security node
The bus of connection is known as the first bus, and the bus that controller is connect with car safety node is known as the second bus.Carriage peace
Full node is responsible for receiving the sensor of all cab portions or safety device information, and by the second bus transfer to controller,
By the electric power decoupler inside closing or opening controller, corresponding safety and non-safety function are executed.
And a kind of elevator safety system is proposed in Chinese patent 00804551.8, by controller and hoistway security node,
Car safety node is connected with an electronic security(ELSEC) bus, when controller judges that elevator needs to enter safe condition, informs electricity
Ladder driving and brake apparatus execute elevator brake for it.
Two above patent utilizes safety bus, and the safeties signal in lift car and hoistway is transmitted to control
Device carries out logic judgment by controller.Since carriage absolute position transducer acquires absolute position or the speed of carriage, and adopt
It is transmitted with safety bus mode, so needing for the absolute position of carriage or speed to be first transmitted to attached using above two patent
Close security node, then the information is transmitted to by controller by other safety bus.As such, it is desirable to total by two safety
Line, controller can just receive absolute position or the velocity information of carriage, and the delay of communication and security node processing information need
Time the absolute position for making carriage or velocity information are become to lag, will affect the execution of security function when serious.
Common elevator safety system, control cabinet pass through cable connection with the velometer being mounted on traction machine, and acquisition is draged
Draw the revolving speed of machine, and then extrapolate lift car actual speed, but due to being connected between traction machine and lift car by wirerope
It connects, the inevitable Relative sliding for generating wirerope stretching, shake and wirerope and traction machine race, for the position of carriage
And there are certain deviations for speed acquisition.
Common elevator safety system has plenty of assessment unit and harness and switch contact combinational logic is used to judge sedan-chair merely
The velocity amplitude in compartment whether safely, judge whether occur open the door in the case of carriage accidental movement, judge whether occur do not subtract normally
The situation of speed, the reliability for judging assessment unit itself, complex circuit.It also can not be accurate because layer door state can not be obtained accurately
Door zone position is obtained, can not accurately realize that carriage accidental movement is protected；Simultaneously because logic is complicated, cause false triggering risk compared with
Height provides that above-mentioned failure needs professional to reset after setting out according to standard, will affect elevator reliability and passenger in this way
Ride experience；
Common elevator safety system, have plenty of through the velocity amplitude of universal serial bus logic judgment carriage whether safely, sentence
The disconnected carriage accidental movement whether occurred in the case of opening the door judges whether abnormal the case where slowing down occur, judges assessment unit
The reliability of itself, car position and velocity information first pass through the first safe serial bus transmission to car node, by carriage section
Point itself judges or using the second safe serial bus transmission to assessment unit, by carriage assessment unit combination while uploaded
Safety device state carries out the assessment of above-mentioned security function.First, since car position and velocity information have passed through the first safety
Universal serial bus, has already passed through certain time-delay, with the information of car safety device is not same time point when reaching car node
Information, no matter these information transfer to assessment unit or car node to judge or assess at this time, obtained result is not quasi- enough
Really；Second, with compared with multinode on the second safe universal serial bus, the information content for needing to transmit is also more, so the transmission of setting
The safe universal serial bus of speed ratio first is slow, in this way, reaching the car position and velocity information of assessment node after being delayed twice
It will more lag, especially when elevator speed is very fast or hoisting depth is higher, delay will bring more serious information delay, comment
The result estimated differs greatly compared with truth.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of elevator safety systems, can accurately obtain position and the speed of carriage
Degree, the quick low time delay of energy obtains the real time position and velocity amplitude of carriage, can obtain accurate assessment result, accurate to realize that uplink surpasses
