Design And Implementation Of Elevator Hand-held Operator Software

China is the world’s largest manufacturing country.In recent years,China’s manufacturing industry has improved tremendously in the level of informatization,technology,and independent innovation.Elevator manufacturing plays an important role in China’s manufacturing transformation,promoting urbanization and import and export trade.There are more and more electronic products supporting elevators,among which elevator handheld operators are one of the important electronic devices.Elevator maintenance personnel can realize information query and parameter setting through the interaction with the elevator main control system,so as to achieve the purpose of efficient operation of the elevator and maintenance of the elevator.It has the characteristics of easy operation,strong real-time performance and good anti-interference ability.It has good portability in various types of elevator products.This paper designs and implements a software system for elevator handheld operators based on the actual needs of the partner companies.The operator collects the data of the elevator main control system,processes the collected data according to the actual needs,and can also display the data graphically.The operator and the main control system exchange data through CAN bus.Aiming at the design and implementation of the elevator handheld operator software,this article mainly includes a parameter monitoring module,an interface display module and a data communication module.The parameter monitoring module mainly implements the basic functions of the operator data processing,and realizes the overall control of the operator.When the user needs to check the parameters of the main control system,it can be implemented through data query operations.When the parameters of the main control system need to be modified,it can be implemented through data setting operations.After the parameter query or modification is completed,the completion time is displayed in the refresh record to distinguish it from the previous operation.After the system is updated,you can add or delete parameters through the parameter increase and decrease functions.The interface display module mainly visualizes parameter display windows,status switching buttons,and function operation buttons.The data communication module encapsulates the data through the formulation of the communication protocol and transmits it through the CAN bus.The operator divides the parameters required by the main control system into elevator status parameters,complete set selection parameters,door status parameters,self-learning parameters,and recording parameters.Among them,the elevator status parameters mainly include the main control standby parameters,mode and status parameters.The complete set of selection parameters mainly include the call registration floor,floor height and number of baffles,running direction and dockable array.The door status parameters mainly refer to the opening and closing status of the door,the time to open the door in place,the time to open and close the door,and the number of failed opening and closing times.The self-learning parameters mainly record the hoistway information parameters learned by the elevator in the self-learning operation mode.The record parameters mainly refer to the operation record and fault record parameters.The operation record contains the time and frequency of the operation.The fault record mainly includes the fault code,fault level,and the current mode and status of the elevator.After the design is completed,the functions and practicability of each part of the operator are tested and analyzed,and the implemented functions are verified according to the use case analysis.The test results show that each functional module of the operator can meet the actual needs,and trials have been carried out in the actual test tower.
