It should be noted that in this embodiment of the invention, it is real-time that the car movement data uploaded in real time includes elevator
Data and elevator functions code parameter two large divisions.Elevator real time data is the data that elevator runs real-time change, there is the reality of elevator
When floor, running status, door state, inspecting state, malfunction, car plate, car top plate and each input and output terminal of master control borad
State etc., the real-time change that elevator is run can be observed by elevator remote monitoring system；Elevator functions code parameter is also real
Shi Gengxin, any one parameter, as long as have change or change, this parameter then pass at once remote monitoring server 1 and in time more
Newly, the moment is consistent with car movement data, as preferred, and the elevator functions code parameter of every elevator can pass through at any time moves
The export Excel forms such as dynamic terminal, computer.In addition, the data of elevator faults, the data of overhauling elevator, are stored in remote monitoring
On server 1, and it is available for query statistic.Specifically, elevator is when breaking down, remote monitoring server 1 preserves generation at once
All data of elevator of failure, including the real time data of elevator and elevator functions code parameter when breaking down, and to the electricity of preservation
Terraced fault data and overhauling elevator data also can be directly viewable or export Excel data files, occur for analyzing this elevator
The reason for failure, give accurate feasible technical support to field service personnel in time.
In this embodiment of the invention, by statistical module 23, make a kind of elevator long-distance monitorng system of present disclosure
System realizes three big statistical functions：
Elevator faults data statistics：Statistical can be carried out according to the need for difference to the data of elevator that are broken down
Analysis, its statistical result is divided into：Customer name statistics, failure code are counted, maintenance staff count, maintenance staff register, and the time unites
Meter, range statistics, fault rate statistics, repair time statistics etc.；In addition, condition limitation can be carried out as needed to statistical result,
Condition limitation have customer name, failure code, maintenance staff, maintenance staff register the time, zone name, fault rate, when repairing
Between, province, city, initial time and termination time etc., and according to different statistical result requirements, different conditions can be selected
Limitation.
(2) elevator maintenance data statistics：Statistical can be carried out according to the need for difference to the car movement data of maintenance
Analysis, its statistical result is divided into：Customer name statistics, maintenance staff are counted, maintenance staff register time statistics, range statistics, dimension
Guarantor leads statistics, maintenance time statistics etc.；In addition, can carry out condition limitation as needed to statistical result, condition limitation has client
Title, maintenance staff, maintenance staff register the time, zone name, maintenance rate, the maintenance time, province, city, initial time and
Termination time etc., and according to different statistical result requirements, select different condition limitations.
(3) elevator guest flow statistics：Using Digital Image Processing mode, i.e., the camera installed by elevator, collection electricity
People in image in ladder, the Digital Image Processing function of then being designed by elevator remote monitoring system 1, collection analysis elevator
Head quantity and change, to count elevator flow of the people, then count elevator in each period, the flow of the people feelings of every floor layer
Condition, and available Excel forms export statistical result, can be referred to as the data analysis of elevator design.
In this embodiment of the invention, statistical result showed module 24 is counted with the elevator faults of statistical module 23 respectively
Module 231, elevator maintenance data statistics module 232 and elevator guest flow statistics module 233 are connected, for statistical form, cake
The mode of shape figure, block diagram or curve map show elevator faults statistical module 231, elevator maintenance data statistics module 232 and
The statistical result of elevator guest flow statistics module 233, while statistical result can also be exported with Excel forms, as electricity
The data analysis reference of ladder design.
In this embodiment of the invention, data analysis module 25 is connected with statistical result showed module 24, for institute
The analysis of elevator maintenance quality, Lift usage ratio and elevator energy consumption efficiency is stated, with statistical form, cake chart, block diagram or curve
The mode of figure shows the elevator faults statistical module, elevator maintenance data statistics module and the elevator guest flow statistics mould
The result of analysis and the data mining of block statistical result, while the knot of analysis and data mining can also be exported with Excel forms
Really, the data analysis as elevator design is referred to.
As preferred, in this embodiment of the invention, data analysis module 25 includes elevator maintenance quality analysis list

To mark result；Analysis result can also be exported with Excel forms simultaneously, the data analysis as elevator design is referred to.
Relating module 26 is used to store elevator ID, for when remote monitoring terminal 3 uploads car movement data, according to electricity
Terraced service data is matched with the elevator ID stored, so as to realize that the auto-associating of elevator and remote monitoring server 1 is recognized.Specifically
, when remote monitoring terminal 3 being installed at the scene, any setting is done without to remote monitoring terminal 3, only need to be by remote monitoring terminal
3 basic circuit is connected, and remote monitoring terminal 3 can just be realized with remote monitoring server 1 and associated automatically according to elevator ID, accurate
The car movement data of true every elevator of upload.Wherein, elevator ID correspondences only one elevator, it uses one of elevator admittedly
Determine function code parameter, this function code parameter is only used as the elevator ID identifications of remote monitoring terminal 3, and this function code parameter is in every electricity
Set between ladder unique；Meanwhile, in remote monitoring server 1, the corresponding elevator ID values of every corresponding elevator curriculum offering,
So as to which same of scene elevator changes the automatic identification that any remote monitoring terminal 3 does not affect car movement data.
Automatically call dispatching module 27 together, be connected with service calls server 5, wherein, service calls server 5 is used to receive client
Or the request phone and sending the information of client or maintenance staff to automatic call together after request phone is received of maintenance staff is repaiied
Module 27, calls information searching corresponding elevator of the dispatching module 27 according to client or maintenance staff together automatically.Specifically, when have client or
Maintenance staff etc. put through phone to the end of service calls server 5 contact staff when, service calls server 5 is by client or maintenance
The information of personnel is sent on remote monitoring server 1 and calls dispatching module 27 together automatically, then the automatic spring of remote monitoring server 1
The client of phone or the information of maintenance staff are put through to interface, and the elevator of this client of quick indexing and maintenance staff under one's name,
So as to which the demand for quickly understanding client and maintenance staff is serviced there is provided rational in time.
Login module 28, mobile terminal 6 and PC 7 are connected with login module 28, for Telnet remote monitoring service
