Summary of the invention
The purpose of this invention is to provide a kind of elevator protection device of monitoring elevator real-world operation speed and realizing the car position protection by bar code sensor detector bar shape code, the accuracy of this device is high.
For achieving the above object, the technical solution used in the present invention is: a kind of elevator protection device, comprise in the hoistway that is fixedly installed on elevator and have along the vertical direction the evenly bar code band of spaced a plurality of bar codes, be contained in the bar code sensor that after detecting a described bar code, to export an impulse singla on the car of described elevator or the sedan-chair frame, being electrically connected with described bar code sensor can be according to the pulse count of this bar code sensor output, centre distance between the time of run of elevator and adjacent two the described bar codes calculates the elevator main control board of elevator real-world operation speed, the lift car automatic leveling is to all corresponding described bar code in the position of every one deck, the position of this lift car between adjacent two layers be all corresponding at least one described bar code also, all be accompanied with unique separately information data in each bar code of described bar code band, the elevator real-world operation velocity amplitude that calculates at described elevator main control board surpass the rated speed of lift value 15% the time, this elevator main control board output hypervelocity breakdown signal; Described elevator main control board obtain the output of described bar code sensor have the impulse singla of unique information data the time, this elevator main control board obtains lift car residing actual position in hoistway by computational analysis, and the deceleration distance of this car when being about to flat bed; When elevator cabin flat level, the level position that the lift car that described elevator main control board obtains is set in actual position of living in and this elevator main control board in hoistway not simultaneously, this elevator main control board output error signal.
Each described bar code all is that black stripe and the arrangement of white room different by width, that reflectivity is different forms.
Because the utilization of technique scheme; the present invention compared with prior art has following advantages: this elevator protection device; adopt bar code sensor detector bar shape code; the impulse singla that obtains is sent in the elevator main control board; realize elevator speed protection and guarded by location function by the elevator main control board computational analysis; the accuracy of this assembly monitor elevator overspeed and car position is high, and good reliability has increased the elevator Operation safety.

Description of drawings
Accompanying drawing 1 is scheme drawing of the present invention.

The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to shown in Figure 1, a kind of elevator protection device comprises bar code band 1, bar code sensor 2, elevator main control board, and bar code band 1 is fixedly installed in the hoistway of elevator, for example is fixed on the guide rail of elevator.Bar code band 1 has along the vertical direction evenly spaced a plurality of bar codes 11, each bar code 11 all is to be worked out according to certain coding rule by width difference, different black stripe and the white rooms of reflectivity, be a kind of in order to express the graphical identifier of set of number or alphabetic character information, all be accompanied with unique separately information data in each bar code 11.Bar code sensor 2 is contained on the car or sedan-chair frame of elevator, for detection of bar code 11.Bar code sensor 2 is along with the car lifting, whenever detecting impulse singla of a bar code 11 rear outputs to elevator main control board, elevator main control board and bar code sensor 2 are electrically connected, adopt the RS232 communications protocol to carry out communication, when elevator moves, elevator main control board receives the impulse singla that bar code sensor 2 detector bar shape codes 11 obtain, and paired pulses is counted, the setting pulse count is n, t is the time of run of corresponding n the pulse of elevator, m is the centre distance between adjacent two bar codes 11, then the real-world operation speed of elevatorV=
M/s
, elevator main control board can make comparisons with rated speed of lift after calculating the real-world operation speed of elevator, if the elevator real-world operation velocity amplitude that elevator main control board calculates surpass the rated speed of lift value 15% the time, elevator main control board can be exported the hypervelocity breakdown signal.In a plurality of bar codes 11 of bar code band 1, the lift car automatic leveling is to all corresponding bar code 11 in the position of every one deck, the position of this lift car between adjacent two layers be all corresponding at least one bar code 11 also, for example in Fig. 1, set unique information data 5 corresponding lift car automatic levelings subsidiary in the bar code 11 to the position of one deck, the position of subsidiary unique information data 10 corresponding lift car automatic levelings to two layer in the bar code 11, then have four bar codes 11 between 5 and 10, the position of lift car between one deck is with two layers be corresponding unique information data 9 of attaching successively from top to bottom, 8,7,6 bar code 11.The bar code sensor 2 on the car has suitable distance of reaction L between bar code sensor 2 on the car and the bar code 11, so that over against a bar code 11 time, can stably obtain an impulse singla.Elevator main control board obtain bar code sensor 2 outputs have the impulse singla of unique information data the time, this elevator main control board can obtain lift car residing actual position in hoistway by computational analysis, and the deceleration distance of this car when being about to flat bed, thereby car can be realized accurate level; When elevator cabin flat level, if the level position that the lift car that elevator main control board obtains is set in actual position of living in and this elevator main control board in hoistway is not simultaneously, this elevator main control board output error signal.By Fig. 1, if the information data that contains in the impulse singla that elevator main control board obtains is 5, show that then lift car is corresponding to the position of one deck at this moment.When elevator cabin flat level; if the level position of setting in the elevator main control board is one deck; and the elevator main control board analysis finds that the information data that contains from the impulse singla that bar code sensor 2 obtains is 6; surmounted level position when then showing the car orderly shutdown; master control board reports an error, and realizes the position limitation protection function.
This elevator protection device adopts bar code, bar code sensor and elevator main control board to be used, and realizes elevator speed protection and guarded by location function, and the accuracy of monitoring elevator overspeed and car position is high, good reliability, and speed is fast, and the life-span is long.
