A kind of stacking apparatus that is used for elevator
Technical field
The utility model relates to the video superimpose technology, refers more particularly to the stacking apparatus that is used for elevator.
Background technology
The elevator video monitoring system just directly is sent to the video data in the lift car in the monitor by coaxial cable at present, can only monitor the video in the elevator sedan-chair, can not reflect information such as elevator floor, up-downgoing, fault, when elevator breaks down, Surveillance center can not report to the police automatically, can only could find elevator faults by the calling of car warning system, and can only give an oral account by the car passenger and can know that just elevator breaks down at that floor, will form like this elevator break down handle untimely.Because the different employed agreement difference of elevator producer, the therefore present stacking apparatus that is used for elevator of the prior art can't directly collect the operation information of elevator usually from apparatus for controlling elevator, in order to collect the operation information of elevator, need install the elevator floor harvester additional for every layer at the hoistway of elevator, and the video information that is transferred to Surveillance center need be passed through different cables with operation information, and the cost or the cost of stacking apparatus itself that therefore install the elevator floor harvester additional are all very high.
The utility model content
The utility model relates to a kind of stacking apparatus that is used for elevator, can in time find the floor fault, reduces product cost.
A kind of stacking apparatus that is used for elevator of the utility model comprises: video input interface, character laminating module, first communication interface and video output interface; Described video input interface is used to receive the video data of camera collection; Described first communication interface is connected with apparatus for controlling elevator, receives the operation information of elevator; Described character laminating module is used for the operation information of described elevator is resolved, and the operation information of the elevator after will resolving and described video data are treated to superposition of data; Described video output interface is connected with monitor, is used to transmit described superposition of data to described monitor.
Wherein, described video input interface and described video output interface can comprise bnc interface.
Wherein, described first communication interface comprises: RS232 communication interface, RS485 communication interface, self-defined communication interface.
Wherein, described character laminating module comprises: single-chip microcomputer, character overlap chip, synchronization signal processing circuit and library stores chip;
Described single-chip microcomputer is connected with described first communication interface, is used to resolve the operation information of described elevator, and controls described character overlap chip work;
Described synchronization signal processing circuit is connected with described video input interface, is used for described video data is separated with synchronously;
Described character overlap chip be used to receive the operation information of the described elevator after the parsing and separate and synchronously after video data, control signal according to described single-chip microcomputer is obtained corresponding character pattern from described character storage chip, described character pattern and the video data that receives are superposeed, and send by described video output interface;
Described library stores chip is used to store and the corresponding character pattern of the operation information of described elevator.
This device is installed in the elevator(lift) machine room control cubicle, can directly gather the elevator operation information in the apparatus for controlling elevator, behind the elevator operation information and vision signal stack that collect, only need send Surveillance center to by one road cable, reduce the wiring from the machine room to the Surveillance center.This device is easy for installation, simple in structure, and cost is low, makes Surveillance center can receive video information simultaneously, can receive the relevant information of elevator operation again, therefore can find the fault of elevator timely.

Embodiment
First embodiment: the stacking apparatus that is used for elevator that the utility model provides, as shown in Figure 1, comprise video input interface, video output interface, the character laminating module and first communication interface, the video data of camera collection is input to the character laminating module by video input interface, first communication interface is gathered the elevator operation information on the apparatus for controlling elevator, and this information sent to the character laminating module, the character laminating module is resolved the operation information of elevator, and to video data separate and synchronously the back generate superposition of data, and be sent to monitor by video output interface.The operation information of elevator can comprise literal or pictures such as elevator ladder number, up-downgoing information, floor information, maintenance, overload, fault.In order to make the utility model be applicable to various ladder kinds, first communication interface can comprise the interface of various ways such as RS232 communication interface, RS485 communication interface, self-defining communication interface.Because the agreement difference that apparatus for controlling elevator adopted that different ladders are planted, therefore the form and the interface of the operation information of the elevator that sends are also inequality, so the character laminating module need possess the analytical capabilities of corresponding agreement.
In addition, this device character laminating module has the function that signal amplifies, and can increase signal transmission distance.
Embodiment 2, and Fig. 2 is an embodiment of character laminating module of the present utility model.As shown in Figure 2, comprise single-chip microcomputer, character overlap chip, library stores chip, synchronization signal processing circuit.Vin is the video data by the video input interface input among the figure, and synchronization signal processing circuit separates video data and be synchronous.The parsing of the operation information of chip microcontroller elevator and to the controlled function of character overlap chip: single-chip microcomputer receives the operation information of elevator by first communication interface, because the agreement that each elevator producer uses is different, therefore single-chip microcomputer need be resolved according to current agreement the operation information of received elevator, and the operation information of the elevator after will resolving is sent to character overlap chip.In the library stores chip, preserve the relevant character pattern of operation information of elevator, after character overlap chip is received the operation information of the elevator after the parsing, the Single-chip Controlling character overlap chip obtains corresponding character pattern or picture dot matrix from the library stores chip, and dot array data and video data are processed into superposition of data.After finishing, stack is sent to monitor by video output interface by the Single-chip Controlling character overlap chip.
Above-described embodiment of the present invention does not constitute the qualification to protection range of the present invention.Any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection range of the present invention.
