In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, being the flow diagram of elevator operation control method provided in an embodiment of the present invention, the control of elevator
System includes controller and the encoder for being attached to traction machine, the elevator operation control method specifically includes the following steps:
Step S1: controller and encoder carry out communication verifying after being respectively completed self-test, through handshake method.It is above-mentioned from
Inspection specifically includes hardware check and software self-test, if self-test does not pass through, system reports an error, and no longer executes subsequent step.
Step S2: it after communication is verified, is compiled according to the second of the first coding of encoder storage and controller storage
Code carries out encoding verification.Wherein, the first coding and second be encoded to customer ID code, it is possible to understand that ground, above-mentioned first coding and
Other codings can also be used in second coding.And in encoding verification, to guarantee communication security, the first coding and the second coding can
It is transmitted using cipher mode.
The embodiment of the present invention realizes encoder and client by communications protocol (different communication protocol can be used in different clients)
Control system (terminal electric life controller) binding.Terminal electric life controller can only the such encoder of adapted, can not be in other products
It replaces general, to avoid the use of code violation device, improves the safety of system.
Specifically, when carrying out encoding verification, coding can be added in communication protocol, to be encoded to different clients
Verifying, is verified, continues to communicate；Inconsistent, then display alarm information, prompts client to mismatch, and no longer executes encoder
Signal transmission, traction machine cannot start.
Wherein, above-mentioned encoding verification can specifically be executed by encoder.As shown in Fig. 2, encoder executes encoding verification process
Include:
Step S211: encoder reads the first coding and sends controller for the first coding.
Step S212: controller will be compared from received first coding of encoder and the second coding of storage, and
When first coding is with the second codes match, confirmation encoding verification passes through.
Above-mentioned encoding verification can also specifically be executed by controller.As shown in figure 3, controller executes encoding verification process packet
It includes:
Step S221: controller reads the second coding and sends encoder for the second coding.
Step S222: encoder will be compared from received second coding of controller and the first coding of storage, and
When second coding is with the first codes match, information is verified to controller transmission.
Step S223: controller receive come self-encoding encoder when being verified information confirm encoding verification pass through.
By above-mentioned encoding verification step, so that only when controller and encoder are bound, it could normal control elevator fortune
Row.Above-mentioned binding can be separate unit encoder and separate unit controller is bound, can also more encoders and the binding of many motors control device.
The mode of binding is not limited to using encoder client mode, can be by changing different communication rate, different data check equations.This
Outside, also comprehensive binding of traction machine and encoder and controller can be realized by the mounting structure of change encoder and traction machine；
It can be customized distinct interface circuit or hardware interface form for different manufacturers by changing encoder hardware output interface, into
One step realizes binding；It can deepen the methods of binding complexity by customizing different adaptation PG cards for different clients and be bound.
Step S3: controller controls traction machine operation after encoding verification passes through, according to the position feed back signal of encoder,
Realize that the operation of traction machine controls by closed loop.
Above-mentioned encoder uses absolute value encoder, avoids the pulse technique of incremental encoder low resolution, control system
Processing circuit of incremental coder and software section can be saved, system complexity is simplified, high resolution improves elevator comfort level, mentions
High elevator overall performance, strong antijamming capability improve system reliability and comfort level.In specific implementation, it is exhausted that vernier can be used
To value encoder techniques, high-resolution output, directly output traction machine rotates corresponding different location value, opens again even if having a power failure
Machine can also read current traction machine positional value.Since positional value directly exports, control system can directly read positional value and calculate fortune
The information such as scanning frequency degree.Certain absolute value output principle is not limited to vernier mode, and Gray code, binary code, M sequence code also can be used
Etc. code systems.
In above-mentioned steps S3, above-mentioned absolute value encoder to the position feed back signal that controller exports may include absolute position
Confidence number and orthogonal differential analog signal；Controller controls traction machine operation according to the position feed back signal of encoder, specifically
It may be accomplished by:
Controller verifies absolute position signal according to orthogonal differential analog signal；It is normal in absolute position signal
When, controller controls traction machine according to absolute position signal and runs；In absolute position signal exception, controller is according to difference in orthogonality
Divide analog signal control traction machine operation, prevents elevator device because of lossing signal driving.
Above-mentioned elevator operation control method provides increments of redundancy signal by absolute value encoder, so as to carry out traction machine
Operation is tested the speed and absolute position verification.
It is stored with traction machine parameter and tuning angle in the encoder of the embodiment of the present invention, it is made to have parameter reading and writing and exempt from
Tuber function.I.e. in installation before traction machine dispatches from the factory, the parameter of electric machine is automatically write to encoder by tooling, carries out angle automatically
Encoder is written in tuning angle by tuner operation, and storage tuning angle saves control machine data space, in erecting bed
It is not required to carry out artificial write parameters and tuner operation, saves working hour, reduce to installation personnel technical requirements, improve accuracy, generate
Direct economic benefit.
