Description

Centralized dispatching command system for transportation production operation of railway vehicle service section

Technical Field

The invention belongs to the technical field of railway transportation management, and particularly relates to a centralized dispatching and commanding system for transportation production operation of a railway vehicle service section.

Background

The train service section is one of important units of a railway train running system and is responsible for the businesses such as train operation control command, station freight, passenger transport and the like. The dispatching personnel in the car service section needs to command the generated operation, and the dispatching command efficiency of the car service section and the operation efficiency of freight stations in the jurisdiction range directly influence the railway freight efficiency and the economic benefit of the car service section. Under the existing technical conditions, a train section dispatcher can only complete the planning handover and information collection of a train section with a road bureau and a station through a telephone, record the completion condition of operation by using a paper pen, and finally manually summarize, arrange and report production data step by step.

Therefore, a production scheduling mode supported by an information system is not available, the recording and the transmission of information are completed manually, the management is very inconvenient, the management is very unreliable, and the efficiency of production operation is seriously influenced.

In the prior art, a dispatcher checks the running condition of a train in a TDCS system, contacts a relevant station to receive the train by telephone after confirming that a cargo operation train number arrives at the station, carries out loading and unloading operation, and manually collects and records various indexes needing to be counted. To supervise the actual operation condition of the station, the operator can only contact the station by telephone to know the actual operation condition. The disadvantages of this technique are: the plan, the production progress and the historical data are not supported and managed by an information system, the production operation progress cannot be monitored in real time, and the historical operation information is not reserved. Secondly, index analysis data is filled manually, and is inaccurate and untimely.

In the prior art, the CPIS technical work chart compiling subsystem is a tool for a dispatcher in a management information system to compile a phase plan and carry out dispatching command, and comprises the functions of refining a station class plan, forming a station dispatching phase plan, recording an operation actual performance, analyzing a station work plan cashing condition, a transportation production completion condition and the like. The system displays the laying and drawing and executing conditions of receiving and dispatching trains and shunting plans in real time, so that dispatching personnel and the system can cooperatively complete the tasks of decision, management, dispatching, command and the like of a marshalling station. The disadvantages of this technique are: the CPIS technical operation chart compiling subsystem only compiles arrival, departure and shunting plans of trains aiming at the operation content of a marshalling station, and the functions of real-time issuing and supervision of station loading and unloading operation and construction maintenance plans required for a train service section cannot be met, and further cannot be recorded and analyzed. Secondly, the traffic flow calculation function of the technical work chart compiling subsystem is used for predicting the vehicle parking at a future time point in a station yard, and the loading and unloading states and the quantity of the vehicles need to be calculated in a traffic section, so that the traffic flow calculation result of the CPIS can not be used as a basis and reference for scheduling and making for a traffic section dispatcher. And the technical operation chart compiling subsystem cannot record the vehicle state (name, upper condition and waiting for loading and unloading), so that the technical operation chart compiling subsystem cannot participate in production operation command. The technical operation chart compiling subsystem does not have the functions of counting and analyzing various production indexes and data in the traffic section, such as analysis of stop and stop, counting of unloading number and the like.

The tool for assisting the dispatcher to plan is similar to the software development in China at the present stage. The marshalling station integrated automation system (CPIS) designed by Beijing full-channel communication signal research and design institute is the most advanced marshalling station automation system in China at present, wherein technical operation chart compilation is used as the most important subsystem of the system, the system is an important tool for compiling stage planning, monitoring plan execution and analyzing plan quality, and technical support is provided for automation and intellectualization of marshalling station planning.

The CPIS is directly applied to organization scheduling of transportation and production of the vehicle section, which is obviously not applicable, and the demand functions of many scheduling personnel cannot be met and realized, and scheduling commands cannot be completed. At present, a dispatching and commanding technology which can be applied to transportation and production operation of the vehicle service section does not exist in China, and the realization of the invention is beneficial to filling up the technical vacancy in the aspect and improving the dispatching and commanding efficiency of the vehicle service section.

Detailed Description

The specific technical scheme of the invention is described by combining the embodiment.

As shown in fig. 1, the centralized dispatching command system for transportation and production operations in railway traffic sections includes a centralized management interface, a dispatching plan module, a traffic flow calculation module, a station current vehicle statistics module, a traffic section index statistics module, a production data statistics and analysis module, and a system prompt module.

The system generates a dispatching plan and various index statistics through station operation data collected from a station end, and draws the dispatching plan and various index statistics in a centralized management interface in a graphical mode, and dispatching personnel edit and issue the dispatching plan through information fed back from the centralized management interface to guide station operation.

In consideration of the fact that a dispatcher needs to master the operation progress and the current vehicle state of all stations in a vehicle service section in real time, the invention displays the dispatching plan and the data statistics in a splicing manner in a software interface in a chart form, and plays a role in centralized display of transportation and production operation information. As shown in fig. 2, the centralized management interface is divided into six modules, namely a station current vehicle statistical area, a dispatching plan display area, a whole section index statistical area, a text information box, a function menu bar and user information.

And scheduling a plan display area.

The system is positioned on the right side of the interface and is mainly used for monitoring the operation progress of the station in real time, and the plan edited by the dispatcher and the plan after the station is honored are displayed in the area. As shown in fig. 3, in order to display the plans in order and clearly, the display area is designed in the form of a grid, the abscissa represents time (the green thick vertical line represents hours, the thin vertical line represents minutes, and each grid represents 10 minutes), and the ordinate represents the type of the plan. In addition, there are three vertical lines of special color in the interface: the blue vertical bar represents shift time of the traffic dispatcher, the yellow vertical bar represents shift time of the freight dispatcher, and the purple vertical bar represents current system time. And, with the current system time as the boundary, the left interface is in dark background color to represent the history area, and the right interface is in normal background color. Meanwhile, since the dispatcher usually issues all the dispatch plans within less than 3 hours at one time, the plan display area grid within the range of 3 hours in the future is covered by light yellow every time there is a plan issued by a lot.

The plans edited by the dispatcher are totally four categories, namely an arrival and departure plan, a shunting plan, a loading and unloading plan and a construction and maintenance plan. Therefore, to display these four types of plans collectively, the display area is cut from top to bottom into the following five parts: time axis, arrival area, shunting area, loading and unloading area, and construction and maintenance area.

Time axis: close to the top of the grid, and the time is consistent with that of the grid (10 minutes for one grid). The length of the time axis determines the range of the displayed plans, and all the plans in the range from the first 6 hours to the last 24 hours are displayed by taking the respective shift time of different posts as a standard. Due to the long span of the time axis range, specific date information is displayed above every 12 hours.

The hair arrival area: the line segments are fixed into four lines, the first two lines are named in the up-down direction of the arrival and departure plan, such as Chongqing and Chengdu in the figure, and the last two lines are used for displaying the main line segments of the arrival and departure plan and named as arrival and departure;

a shunting area: the number of lines is not fixed, and is mainly determined by the type of locomotive (state railway shunting machine, enterprise shunting machine and lead locomotive) configured in the station, and when the station has one state railway shunting machine, the number of lines in the shunting area is increased by one, and the name of the state railway shunting machine is named. Particularly, in order to facilitate a dispatcher to manage state dispatching and master dispatching positions, the dispatching names displayed on the interface are respectively black, light blue and dark blue. The color of the green light is dark blue, which indicates that the shunting machine is in the current station and can carry out shunting operation; when the display is black, the state-changing railway switch is not in the station yard currently; and light blue indicates that the tuner is in the zone addressed to the station and can access. If the station is provided with a lead machine or an enterprise machine, two lines are added respectively, and the lead machine and the enterprise machine are named respectively;

loading and unloading areas: the number of rows is not fixed and is determined by the number of cargo lines in a specific station (including a special line), and each row is named by a corresponding cargo line name (special line name);

construction and maintenance area: the fixing is two lines, so as to name the maintenance construction.

And secondly, a station vehicle-present counting area.

And the statistical condition is positioned on the left side of the main interface and used for displaying the current vehicle state of each station in the administration range of the vehicle administration section. The part is presented in a form of a table, divided by station names, and the current vehicle statistical area interface is formed by the current vehicle statistical tables of all stations. As shown in fig. 4.

Particularly, since the sub-areas of the station present vehicle statistical area and the dispatching plan display area are all divided by the station names, it is necessary to keep the heights of the sub-areas of the same station name in the connection part consistent, the principle of implementation is shown in fig. 5, and the following is a detailed description of each step of the height synchronization principle:

step 1: and calculating the height of the current station vehicle statistical area, wherein the height occupied by each name default is one cell height, and the head of the table occupies two cells, and occupies four cells in total, and is fixed.

Step 2: and calculating the height of the display area of the dispatching plan.

And step 3: and (4) judging whether the heights of the two areas are equal, if so, finishing the height synchronization, and otherwise, performing the step (4).

And 4, step 4: the height of the current unprocessed name grid is increased by one grid cell. (treatment was performed in the order from bottom to top, with the first untreated name cell being the bottommost name cell.)

And 5: and judging whether the name lattice just increased to the top is positioned at the top, if so, taking the name lattice at the bottom as an unprocessed name lattice, and otherwise, taking the name lattice above the name lattice as an unprocessed name lattice.

Step 6: and (5) repeating the operation of the step (3).

And the whole section index counting area comprises four modules of double control indexes, real-time data, holding capacity and planned cash rate, and the four modules are respectively designed into a form with the ground color being gray as shown in fig. 6. Particularly, when the real-time data do not meet the index number of the double-control index, the background color of the real-time data statistics is changed into red, and otherwise, the background color is green.

Fourthly, character information frame

The screen is fixed above the interface, as shown in fig. 7, the screen is designed as a text box with a gray background color, historical information can be dragged up and down by using a scroll bar, the progress of operation of a station of a dispatcher is recorded and prompted, and the dispatcher can conveniently inquire and supervise the operation of the station.

Function menu bar

Besides editing the plan, some other function requirements can be implemented in the menu bar by the dispatcher, and as shown in fig. 8, the options in the bar are named by the summary of the implemented functions.

Information of user

At the bottom of the interface, as shown in fig. 9, the name of the logged-in user, the position, the shift, and the line name displayed in the current interface are displayed in text.

The dispatching plan management module comprises four modules of plan division, plan editing, plan query and plan automatic generation

Plan division

According to the job purpose of the dispatching plan, the invention classifies the dispatching plan into four categories. The characteristics of each type of plan are different, the plan information required to be displayed is also different, and the display forms of the plans are also different.

The arrival plan is designed with three representation forms, L-shaped, U-shaped and reverse L-shaped. The numbers on the top horizontal line represent train number, the numbers below represent the ones of the current time minute, and the position of the top horizontal line is in a column of the same hair extension direction as the plan. The starting position of the horizontal line at the lower part is the starting time and the ending time of the plan, and the characters at the upper part record the stock way name of the planned receiving and dispatching train and the marshalling content to be accessed or sent;

the shunting plan has two expression forms, one is the shunting plan of the national railway shunting operation, the shunting plan is expressed by adopting the form of a great wall line in order to record the operation process of the national railway shunting, and is different from other plans in that only an operation planning line is displayed, and based on the requirement of recording all the operation processes, the idle time without operation also needs to be displayed on an interface, and is expressed by a wavy line for displaying the difference, and the shunting plan of the non-national railway shunting operation is expressed by a common line segment. The characters displayed together with the line segments are the destination track of the shunting operation and the specific shunting formation, as shown in fig. 10.

The loading and unloading plan and the construction maintenance plan are displayed on the interface by using common line segments. The characters on the loading and unloading plan line are the loading and unloading type, the loading and unloading name and the loading and unloading number, and the characters on the construction maintenance plan line are the construction maintenance range and reason of the station.

Because the scheduling plan has different schedules and completion conditions in the concrete execution of the station, the scheduling plan is divided into five types according to the completion state: draft, issue, go on, finish and unplanned. The plans for different states are represented in different colors, respectively, as shown in table 1. The specific meanings and display colors for the five states are also given in table 1.

TABLE 1 plan status description

Plan editing

The editing of the scheduling plan comprises four items of adding, modifying, assigning and deleting of the plan. After the dispatcher edits the plan in the centralized display interface each time, the centralized display interface is not changed immediately, but the corresponding plan information recorded in the database is modified through the server, and then the system carries out corresponding processing according to the broadcast of the server. If communication with the server fails or the modified records in the database fail, the system issues a corresponding prompt and the corresponding plan edit operation is also invalid.

The adding plan generates a draft plan of a corresponding type; plan modification is used for modifying certain information or certain information of a planned plan, and only modification operation can be carried out on the plan in a draft or a delivery state, otherwise, the system prompts an operator to prohibit operation, and the plan is changed into the draft state after the modification operation is carried out; the plan issuing can only take effect on the plan in the draft state, otherwise, the system prompts that the plan is in a non-draft state, and after the plan issuing is carried out, a dispatcher needs to carry out secondary confirmation, and the plan can be converted into the draft state (except the state, other information of the original draft plan is not changed); like plan delivery, plan deletion can only take effect on draft plans, requiring secondary confirmation by the dispatcher.

Planning query

As long as the dispatching plans are not deleted by the user, records are recorded in the database, the invention provides a function of inquiring historical dispatching plans through the time of the shift. After historical plan query is carried out, the time axis of the plan display area jumps to the starting time of the query shift, and the scheduling plan in the corresponding time range is displayed.

Meanwhile, for the converted plan, the invention provides the function of inquiring the original plan information for comparing the actual operation of the station with the original plan. The original plan information is displayed below the cashing plan in the form of gray lines, the display position of the cashing plan is determined by the starting time and the ending time of the cashing plan, and the gray characters below the lines are the operation contents which are planned to reach the station. In order to avoid the overlapping, the national railway shunting plan adds a new line below the plan column for displaying the original plan information, and the new line is also displayed in gray. If the plan state is an unplanned plan line, no additional display is needed because the dispatcher does not make the original plan.

If the plurality of plans are overlapped to cause the condition that the plan content is not clearly displayed, the starting and ending time, the issuing time and the operation content of the plan are displayed plan by plan in a label mode.

Automatic generation of dispatching plan

After the external system of the train service section is accessed, the actual running information of each train can be obtained, and the invention also provides a function of automatically generating the dispatching command plan. The arrival, shunting, loading and unloading and departure plans automatically generated by the system are all displayed in a draft state in the centralized display interface. The dispatcher only needs to modify and assign operation on the basis of the automatically generated dispatching plan, so that the operation of the dispatcher is greatly reduced, the workload of the dispatcher is reduced, error deviation caused by a large amount of manual operation is reduced, and the efficiency of production commanding and dispatching is improved. The schematic flow chart is shown in fig. 11, and the following steps are detailed steps for automatically generating a dispatch plan:

step 1: and acquiring the running information of the train, such as train number, arrival time, carried marshalling content and the like.

Step 2: and judging whether the obtained information contains a transfer vehicle, and if so, generating an arrival and departure plan.

And step 3: and judging whether the train carries the working vehicle, if so, generating an arrival plan, and executing the step 4, otherwise, finishing automatic generation.

And 4, step 4: and (4) classifying the vehicles with completely consistent names and vehicle types into a vehicle group, and grouping all the arriving working vehicles.

And 5: and selecting the loading and unloading device for each group of the obtained working vehicles, wherein if the working vehicles are empty, the loading and unloading devices are selected according to the types of the vehicles, and otherwise, the loading and unloading devices are selected according to the names of the vehicles. Thereby determining the cargo line at which the loading and unloading work is completed.

Step 6: and (3) generating a shunting plan for shunting the to-be-loaded and unloaded vehicle to the corresponding cargo line for alignment according to the obtained cargo line (target station track) for loading and unloading operation and the arrival plan generated in the step (3).

And 7: and generating a shunting plan according to the step 6, and generating a corresponding loading and unloading plan according to the type of the vehicle shunted to the cargo line. If the name is contained, the unloading plan is correspondingly generated for the vehicle to be unloaded; otherwise, the vehicle is to be loaded, and a loading plan is correspondingly generated.

And 8: after the end time of the loading/unloading plan created in step 6 is determined, the arrival/departure line to which the train is not involved in the shunting and the train is received/dispatched in the station is determined, and a shunting plan for shunting the loaded/unloaded waiting trailer to the arrival/departure line is created in the idle time period.

And step 9: and generating a departure plan for the trailer to be sent away according to the shunting plan generated in the step 8.

The vehicle service section index statistics comprises three modules of holding amount statistics, double-control index statistics and exchange rate statistics.

Keeping quantity statistics: after the operation of receiving or dispatching the train at the station, the reserved quantity of the train section is correspondingly increased or decreased and is changed in real time.

Counting double-control indexes: the method comprises a planning double-control index and real-time data, wherein the planning double-control index is a target unloading number and a maximum unloading number which are set by a traffic section, and the planning double-control index is fixedly displayed unless the index of the traffic section is changed. The real-time data is the sum of the unloaded number and the number to be unloaded of all stations, the real-time data is displayed in real time, and the real-time data is correspondingly changed every time the stations finish unloading operation or access the stations to be unloaded. After 18 points every day, the real-time data is cleared and counted again.

And (3) counting the redemption rate: the completion condition of the dispatching plan issued by the dispatcher by the station is indicated, and the completion condition comprises the exchange rate of arrival, departure, shunting, loading and unloading plans. And calculating the cashing rate based on the planned operation time issued by the dispatcher. For the dispatching plan in the completion state, the plan completed within 30 minutes before the plan end time is regarded as the plan honored by the station, otherwise, the plan is regarded as not honored. In addition, a plan that is in a state of being issued, in progress, or out of plan is also considered to be not honored. The plan in draft state does not count the statistics of the exchange rate because the station side does not receive the plan. At 6 and 18 points per day, all planned redemption rates were reset to 100% and recalculated.

The numbers under the left double-control index characters refer to the unloading number and the unloading number (from left to right in the figure) specified by the vehicle service section, and the numbers under the real-time data refer to the unloading number and the unloading number of all stations at the current moment; the counting index is the planned loading number of the vehicle service section on the same day, namely the number of empty vehicles applied to the road bureau; the plan exchange rate is the completion condition of each plan (arrival, departure, loading, unloading and shunting) of the vehicle service section; the hold amount is the sum of the number of all work vehicles throughout the segment. And the index statistics are displayed above the main interface in real time, and the operation progress of the station is dynamically changed.

The station current vehicle statistics, which is to sum up data to be counted by the station current vehicle into 7 parts of charging, holding amount, unloading, waiting to unload without upper position, waiting to unload with upper position, waiting to load without upper position, waiting to hang, and respectively counting and calculating the total count (the charging only calculates the total because the name of the charging is unknown):

metering and packaging: the planned loading number of the station is manually input by a dispatcher;

unloading: the total number of unloads from 18 o 'clock yesterday to 18 o' clock today;

waiting for unloading to be on the upper position: the number of vehicles which are loaded with goods in the station and can be unloaded in the goods line;

waiting for unloading not to be on the upper position: the station is provided with a name of a vehicle which does not arrive at a corresponding cargo line or arrive at the cargo line and is not aligned;

waiting for assembly to be up: the number of empty vehicles which can be loaded on a goods line in a station is aligned;

waiting for installation, not up: the number of empty vehicles which do not arrive at the corresponding cargo line or arrive at the cargo line and are not aligned in the station;

waiting for hanging: the number of vehicles which have finished the loading and unloading tasks and need to be sent away in the station.

Traffic flow estimation, a dispatcher can only supervise and view single operation or a few operations through various planning lines in a planning display area, and a current vehicle statistical area on the left side cannot show the operation to be towed and the operation to be loaded more specifically. Therefore, in addition to the above two scheduling aids, the present invention adds the function of predicting and calculating the current vehicle condition at the future station, i.e. calculating the traffic flow, according to the plan of the dispatcher to reach the station and the current vehicle data at the station.

The traffic flow calculation is to classify all vehicles in the station into five types, namely other vehicles, vehicles to be loaded, vehicles to be unloaded, empty vehicles and heavy vehicles, and according to the station data and the dispatching plan, a dispatcher can specifically know the vehicle operation result of each station after a vehicle service section passes through an operation stage (default 3 hours, and manual adjustment is also available). Meanwhile, the calculation result can be directly fed back to the dispatching post as a reference and basis for vehicle allocation at the next stage of the dispatching post. As shown in fig. 12, the following is a detailed procedure for implementing the traffic flow estimation:

step 1: and acquiring all current vehicle data of each station.

Step 2: and classifying the acquired current vehicle data according to other data, to-be-loaded vehicles, to-be-unloaded vehicles, empty vehicles and heavy vehicles. Wherein, the transit vehicle and the non-operating vehicle are classified into other vehicles.

And step 3: all arrival plans which are finished within 3 hours after the current time and are in a given state are regarded as effective arrival plans, current vehicle data can be influenced, and the cart flow result is newly added with the vehicles to be loaded and unloaded on the basis of the step 2. In particular, in order to prevent an operation error of the station staff from not clearing the plan, if there is an unplanned arrival plan whose number of cars is the same as that of one of the valid arrival plans described above and whose end time differs by not more than 6 hours, the arrival plan given here cannot be regarded as valid.

And 4, step 4: and if all loading and unloading plans are finished within 3 hours after the current time and are in a state of issuing or in-progress, the current vehicle data can be influenced, the corresponding to-be-loaded and unloaded vehicles are reduced as a result of the cart flow, and corresponding empty and heavy vehicles are newly added.

And 5: the effective judgment of the departure plan is consistent with the arrival plan, and if the judgment can influence the current vehicle, the corresponding empty and heavy vehicles are reduced.

Step 6: and displaying the cart flow result in a centralized display interface in a form of a table.

The statistics and analysis of the production data are important basis for evaluating the completion quality of the operation in the train section and adjusting the content of the operation of the next shift. Therefore, at six and eighteen points (namely the switching time of the dispatching room in the shift), the invention can automatically carry out statistics and storage on the production data of the dispatching, dispatching and counting rooms, and relevant personnel can check the data at any time. In addition, there is a work vehicle at each station. After the transfer car is sent out, the invention can automatically analyze and store the transfer car when the transfer car stops.

Production data statistics

The following tables 2, 3 and 4 are the shift schedules of the freight dispatching, the line dispatching and the efficiency indexes designed according to the original list of the shift schedule manually filled in each shift of the current vehicle service section. In addition to the number of vehicles requested, the names of the articles to be unloaded and the reasons, at 6 and 18 points of each day, the system automatically collects and calculates the production statistical data of all stations in the current time range of the shift and fills the data (totally counting two time periods, namely 18 points of yesterday to 6 points of the day and 18 points of yesterday to 18 points of the day).

TABLE 2 freight dispatching shift table design

TABLE 3 line-scheduling shift-changing table design

TABLE 4 efficiency index change-to-shift table design

Analysis of mid-stop time

The analysis of the stop-and-go time is an important index for analyzing the operation quality and efficiency of the vehicle service section, and mainly aims at analyzing two types of vehicles, namely a transit vehicle and an operation vehicle in a station, which are respectively called as the analysis of the stop-and-go time and the analysis of the stop-and-go time.

The middle-time analysis means that the arrival time and departure time of all transit vehicle groups from 18 yesterday to 18 today are counted and compared with the planned transit time for analysis, and the middle-time analysis table is shown in the following figure. Wherein, the last three columns: the main reasons of the overtime, the measures taken and the next measures are recorded by the station side, and the others are automatically collected. Table 5 shows the significance of each index analyzed in the middle period.

Time analysis index in Table 5

Name of the index	Of significance
		Name of station	Handle itName of station where transfer vehicle works
Medium time plan	The planned transit time (h) of the station
		Practice of	The station transfers the average transit time (h) of all the vehicles from 18 yesterday to 18 days
Super-super	Actual subtraction of the time (h) of the Medium time plan
		Time-of-impact train set	The transfer cars with the same name, arrival time and departure time are classified into a car group
Name of article	Name of goods carried by transfer car (if not, fill in 'empty')
		Number of vehicles	Number of arrival train of transfer car
Time of arrival	Time when transit vehicle enters station
		Departure time	Time when the transfer car leaves the station
Average transit time	(departure time-arrival time)/number of vehicles (h)

And the stopping time analysis means that all operation time nodes of all the operation vehicles from 18 yesterday to 18 today in the station, namely the arrival time, the incoming line time, the starting operation time and the ending operation time of the vehicles, and the outgoing line time are compared with the scheduled stopping time completion for analysis.

The system automatically classifies all the operation vehicles with the same operation time node into a vehicle group for display, and the operation vehicles are automatically collected except the last three columns recorded by a station side as in the middle analysis, and the table 6 is the description of each time node in the stop time analysis.

In addition, the obtained stopover time analysis table can be saved as an excel table.

TABLE 6 analysis of time of day node description

Time of alignment	Time for finishing alignment of operation vehicle on cargo line
		Average time of rest before entering line	Alignment time-arrival time
Starting time	Time for starting loading and unloading of working vehicle
		Finish time	Time for finishing loading and unloading of working vehicle
Average stop time of loading and unloading operation	Finish time-start time
		Waiting for line-out time	Starting time for calling out goods line after completion of loading and unloading of operation vehicle
Time of outgoing line	End time of calling out goods line after completion of loading and unloading of operation vehicle
		Waiting for outgoing line	Time-waiting for outgoing line
Departure time	Time of departure of work vehicle from station
		Average time of stopping after line outgoing	Departure time-outgoing time
Mean residence time	Departure time-arrival time

The system prompt comprises:

the method includes that the current specific date and time of a system and characters of a server with bottom colors beside the system are displayed under the statistical data of car service section indexes and used for monitoring the communication connection condition of the system and the server, and the bottom colors are designed with three colors of green, yellow and red respectively to represent different communication states, and the meaning is as follows.

Green: the communication with the server is normal.

Yellow: the connection to the server is affected by fluctuations and a reconnection is automatically attempted.

Red: disconnection from the server and failure of reconnection, need to check whether the connection interface or the like is disconnected

Voice broadcasting:

when the station works, the information of the work progress and the application and approval of the security equipment needs to be mastered by a dispatcher in time so as to make corresponding work adjustment and work arrangement of the next stage in time, therefore, after the station receives a car, aligns, loads and unloads, dispatches the car and applies for approval of the security equipment, the system can send out related voice prompts and record the information in a text information frame.
