Description

The invention relates to computing, in particular to an automated system for collecting and processing data from geographically distributed objects, for example, data on ticket sales by geographically distributed airline agencies.

For the operational analysis and decision-making on passenger traffic performed for any given period, as a rule, indicators such as the number of ticket sales for the corresponding flights and, accordingly, the income attributable to each flight are used.

Comparison of the dynamics of changes in these indicators in their interconnection allows us to judge with sufficient probability the potential of the operated market, the structure of passenger traffic (at the profitable rate), the effectiveness of the schedule (the correct placement of aircraft), the correct application of tariffs, etc.

In this regard, the task of collecting and processing data on ticket sales by geographically distributed airline agencies for relevant flights and identifying the most appropriate aircraft layout for obtaining the greatest effect on their use becomes especially urgent.

The first of the known systems contains data reception and storage units connected to control and data processing units, search and selection units connected to data storage and display units, the synchronizing inputs of which are connected to the outputs of the control unit (1).

A significant drawback of this system is the impossibility of solving the problem of online updating of data stored in memory in the form of relevant documents in real time.

The last of the above technical solutions is closest to the described.

In this system, geographically distributed airline agencies act as sources of data on the number of tickets sold for a certain time interval.

Messages about the number of tickets sold for the corresponding flights for a certain period of time are transmitted according to certain rules, according to which airline agencies transmit the total information about the number of tickets sold at certain points in time, for example, at the beginning of each hour.

We will consider the operation of the system using an example of solving the basic functional tasks of the system related to both receiving and processing data on the number of tickets sold for the corresponding flights, and obtaining final data on the results of sales at all territorially distributed airline agencies.

When solving the problem of collecting and processing data on the number of ticket sales for information input 22 of the system, in accordance with the established regulations on the data transmission path, messages (codograms) from airline agencies are sequentially received, having the following structure:

THE CODE THE CODE THE CODE THE CODE Sign

The codegram code from the information input 22 of the system is entered into the register 150 of block 6 by a synchronizing pulse from input 25, which passes to the synchronization input of register 150 through element 152 I, which is open at the second input with high potential from the inverse output of trigger 151, which is in the original source code before the first code condition.

From the output 155 of block 6, the sign code of the input message is sent to the input 93 of block 3 and then fed to the input of the decoder 82, which decodes the code of the sign of the input message and, in this case, opens the And element 87 And one input.

At the same time, from the exit 156 of block 6, the Aeroflot agency identifier code goes to the information input 166 of block 7 and then to the input of the decoder 161, which decrypts the incoming code, giving out one of its outputs high potential. For definiteness, we assume that a high potential is received at one input of element 164 I.

At this time, the synchronizing pulse from the output of the element 152 AND block 6 is delayed by the element 153 while receiving the code of the input message in the register 150 and the operation of the decoder 161 and then, firstly, it goes to the single input of the trigger 151 and sets it to a single state, in which from the inverted output of the trigger will be issued a low potential at the input of the element 152 And, blocking the reception of the next message.

Secondly, the same synchronizing pulse from the output 158 of block 6 goes to the input 167 of block 7, from where it polls the states of elements 162-164 I.

Considering the fact that only element 164 I will be open at one input, then, having passed this element I, the clock pulse arrives, firstly, at the read input of a fixed memory cell of read-only memory 160, where the base address of the memory cell is stored in the server database assigned to this Aeroflot agency, and reads its contents through exit 168 to input 121 of block 4.

From the input 121 of block 4, the code of the base address of the agency that sent the input message passes through the elements 118 OR groups to the information inputs of registers 111 and 112.

Secondly, the same pulse of reading the code of the base address of the agency from the output of the element 164 AND block 7 passes the element 165 OR to the output 169 of the block 7 and then goes to the input 94 of the block 3, where it is delayed by the delay element 88 for the time of reading the contents of a fixed ROM cell, passes through element 87 And opened by decoder 82 and then, firstly, passes through element 83 OR to output 98 of block 3 and then passes through input 123 of block 4 to the synchronizing input of register 111, fixing the base address of the memory cell assigned to it agency.

Secondly, the same pulse from the output 99 of block 3 is fed to the input 124 of block 4 and then fed to the clock input of the register 112, also fixing in it the base address of the memory cell assigned to this agency.

Thirdly, the same impulse is delayed by element 90 while the agency’s base address is entered in registers 111 and 112, and then through OR element 84 and output 100 of block 3 is output to system output 33 and then to the input of the first server interrupt channel (not shown in the drawing )

Based on this signal, the server goes to the subprogram for querying the contents of the database at the agency’s base address, which, from the output of register 111 through elements 113 AND of the group opened by high potential from input 126 of block 4, and through elements 117 of the OR is sent to address 30 of the system.

The contents of the base address of this agency is read from the server database and through the information input 23 of the system goes to the information input of the register 12, where it is entered by the synchronizing pulse of the server received at the synchronizing input 26 of the system.

It should be noted that before the system started to work, all its nodes and blocks were set to the initial state, and the contents of the server database cells were reset.

In this regard, with the arrival of the first message from this agency, when reading the contents of its base address to the input of register 12, a zero code will be read and, therefore, register 12 will remain in its original state.

The contents of register 12 (in this case, it is equal to zero) is fed to input 202 of block 10 and then through elements 196 And the groups open at input 205 of block 10 with high potential from the inverse output of trigger 41 of block 1 are fed to one input of adder 195.

To other inputs of adder 195 from input 203 of block 10, a code of the number of ticket sales according to the data of the Aeroflot agency that sent this message was submitted.

The pulse of entering the code into the register 12 from the input 26 of the system enters the synchronizing input 204 of block 10, is delayed by the time the code is entered into the register 12 by the delay element 199, passes through the element 197 AND, also opened at the second input by a high potential from input 205, and is fed to the synchronizing input of the adder 195, the output of which is formed the total amount of ticket sales made by this agency.

The resulting sales amount from the output 206 of block 10 goes to the input 215 of block 13, then the elements 211 AND of the group open with high potential from the input 217 pass, and then through the elements 212 OR of the group it is transmitted to the information output 32 of the system, from where it is issued to the information input of the server , to the address input of which the base address of this agency from address output 31 of the system is still filed.

The pulse from the output of the element 197 of block 10, delayed by the delay element 200 for the response time of the adder 195, and through the output 207 of block 10 is supplied to the input 187 of block 9 and then to the counting input of the counter 180, which counts the number of aeroflot agencies that sent messages in this time interval.

Secondly, the same pulse is delayed by the delay element 186 of block 9 for the response time of the counter 180 and is sent to the synchronizing input of the comparator 182. By this signal, the comparator 182 compares the number of agencies that sent messages and recorded in the counter 180, with a given number of agencies in the register 181 who should send their messages.

If the number of agencies that sent messages is less than the specified number stored in the register 181, then a signal is generated at the output 230 of the comparator 182, which passes through the output 188 of block 9 to the input 96 of block 3, the OR element 85 passes, and from the output 101 to output 34 system.

From the output of the system 34, the data recording control pulse is input to the second channel of the server interrupt. By this signal, the server goes to the recording subroutine and writes to the base address on the address output 30 of the system the total amount of sales for a given time of the day in this agency issued by the system to information outputs 31 and 32.

In parallel with the process of generating the base address of this agency in block 4, the code of the base address from the output of register 112 of block 4 goes to one input of adder 110, to the other input 122 of which the code comes from output 189 of block 9.

The adder 110 performs the function of modifying the base addresses of the agencies in order to bind them to specific values of the time intervals within which aeroflot agencies report new data. The formation of the modified base addresses is intended for the orderly documentation of all received messages from agencies directly in the process of receiving messages and is carried out using block 9.

Block 9 is designed to record times at which, in the next time cycle of receiving messages from aeroflot agencies, the fact of receipt of messages from all working agencies will be recorded.

To this end, in the process of implementing the next cycle of receiving messages from agencies, the next impulse to control the recording of new content at the base address from the output 207 of block 10 goes to the input 187 of block 9 and then to the counting input of the counter 180.

As soon as the readings of the counter 180 are equal to the readings of the register 181, according to the signal polling the status of the comparator pulse from the output of the delay element 186 to the clock input of the comparator 182, the comparator 182 will give a signal to the output 231.

This pulse, firstly, enters the counting input of the counter 183, counting the number of time intervals, in this case, the first unit is entered in the counter 183.

Secondly, after a delay by the element 185 for the time of operation of the counter 183 and trigger 184, it arrives at the installation input of the counter 180, returning it to its original state and preparing for the next cycle of receiving messages.

Thirdly, the same pulse arrives at the single input of trigger 184 and sets it to a single state, in which the output 192 will have a high potential, and the output 191 will be low.

Trigger 184 low potential from its inverse output 191 closes one input element 113 And block 4, thereby blocking the connection of the output of the register 111 of block 4 to the address output 30 of the system, and, conversely, high potential from its direct output 192 trigger 184 opens the elements 114 And groups on one input, thereby connecting the output of the adder 110 through elements 114 AND groups and elements 117 OR groups to the address output 30 of the system.

And finally, fourthly, the synchronizing pulse delayed by the counter 183 and trigger 184 from the output 190 of block 9 is fed to the input 125 of block 4 and then to the synchronizing input of the adder 110.

With the arrival of each clock pulse from the output 190 of block 9 to the clock input of the adder 110, the latter generates a modified base address by sequentially adding to the base address the number of message receiving intervals from the corresponding agencies.

At the information 31 system output at a given time from the output 157 of block 6 through the input 214 of block 13, elements 210 AND groups, elements 212 OR groups, the code of the number of sales performed by this agency was submitted at the time of receiving the message, and the code output 32 was issued recording from the output of block 158 6.

The synchronizing pulse from the synchronizing input of the adder 110 is delayed by the element 116 for the duration of the operation of the adder 110 and then from the output 128 of the block 4 it goes to the input 97 of the block 3, where the OR element passes 85 and from the output 101 of the block 3 it is output to the output 34 of the system, from where it goes to input of the second channel of the server interrupt.

By this signal, the server goes to the subroutine to record the message sent to the modified address.

Thus, all messages sent by a particular agency will be sequentially documented with a strict reference to its base address, and the contents of the base address of this agency will represent the accumulating amount of the number of sales performed at this time in this agency.

Along with the final calculation of the number of sales in each of the Aeroflot agencies, the system generates the total number of sales from all agencies directly in the process of receiving messages from Aeroflot agencies.

To this end, the output 157 of block 6 is connected to the information input 218 of the accumulating adder of block 11, which, according to the synchronizing pulse from the output 158 of block 6, forms the cumulative result of the number of ticket sales.

The total data on an accrual basis from the output of block 11 is received through the input 142 of block 5 to the inputs of the elements 132 of the group.

Similarly, the system works in solving the functional task of receiving summary ticket sales data from all aeroflot agencies, transmitted as of a given time, for example, at 00 o’clock of the next day.

When solving this functional problem, the information input 22 of the system in accordance with the established regulations on the data transmission path consistently receives messages (codograms) from aeroflot agencies having the following structure:

THE CODE THE CODE THE CODE THE CODE Sign
input message


Identifier
Aeroflot agencies


Total number

Other attributes
sales including data on
number of seats

relevant Aeroflot flights

The codegram code from the information input 22 of the system is entered into the register 150 of block 6 by a synchronizing pulse from input 25, which passes to the synchronization input of register 150 through element 152 I, which is open at the second input with high potential from the inverse output of trigger 151, which is in the original source code before the first code condition.

From the output 155 of block 6, the sign code of the input message is sent to the input 93 of block 3 and then fed to the input of the decoder 82, which decodes the code of the sign of the input message and, in this case, opens the And 86 element through one input.

In parallel with this, from the output 156 of block 6, the code of the election commission identifier goes to the information input 166 of block 7 and then to the input of the decoder 161, which decrypts the incoming code, giving out one of its outputs high potential. For definiteness, we assume that a high potential is received at one input of element 162 I.

At this time, the synchronizing pulse from the output of the element 152 AND block 6 is delayed by the element 153 while receiving the code of the input message in the register 150 and the operation of the decoder 161 and then, firstly, it goes to the single input of the trigger 151 and sets it to a single state, in which from the inverted output of the trigger will be issued a low potential at the input of the element 152 And, blocking the reception of the next message.

Secondly, the same synchronizing pulse from the output 158 of block 6 goes to the input 167 of block 7, from where it polls the states of elements 162-164 I.

Given the fact that only one element 162 I will be open at one input, then passing through this element I, the clock pulse arrives, firstly, at the read input of a fixed memory cell of the permanent storage device 160, where the base address of the memory cell is stored in the server database, assigned to this agency, and reads its contents through output 168 to input 121 of block 4.

From the input 121 of block 4, the code of the base address of the agency that sent the input message passes through the elements 118 OR groups to the information inputs of registers 111 and 112.

Secondly, the same pulse of reading the code of the agency’s base address from the output of element 162 AND passes through element 165 OR to output 169 of block 7 and then goes to input 94 of block 3, where it is delayed by delay element 88 for the duration of reading the contents of a fixed ROM cell, passes through the 86 element opened by the decoder 82 And then, firstly, it passes through the OR element 83 to the output 98 of block 3 and then through the input 123 of block 4 it goes to the synchronizing input of register 111, fixing the base address of the memory cell assigned to this agency in it.

Thirdly, the same impulse from the output of element 86 AND block 3 is delayed by element 92 while the base address code is entered in block register 111, OR element 85 passes and from output 101 of block 3 it enters system output 34 as a data recording control pulse.

The control pulse of the data recording is fed to the input of the second channel of the server interrupt. Based on this signal, the server switches to the recording subroutine and writes the contents of the summary data from the specified agency, issued by the system to the information outputs 31 and 32, at the base address on the address output 30 of the system.

In addition, each synchronizing pulse of writing the summary data to the database from the output 101 enters the input 175 of block 8, from where it is fed to the counting input of the counter 171, fixing the number of final data sent by agencies. The operating number of airline agencies has been entered in register 172. The readings of the counter 171 through the signal output 38 of the system are displayed on the display panel.

Each synchronizing pulse received at the input 175 of block 8 is delayed by element 173 for the time the counter 171 operates and is fed to the synchronizing input of the comparator 170, which compares a given number of agencies with the number of agencies recorded by the counter 171.

As soon as the readings of the counter 171 and the register 172 are equal, a signal about the readiness of the summary data from all agencies for summing up the final results will be issued to the second signal output 39 of the system.

As noted above, the end of the operation of receiving messages from agencies is fixed by block 9, the signal from the output 190 of which also goes to the control 47 input of block 1 and sets the trigger 41 of the mode to a single state, in which the low potential from the inverse output is from the output 54 of block 1 arrives at input 205 of block 10, where it blocks the operation of elements 196 AND of the group and element 197 I.

In addition, the high potential of the trigger 41 of block 1 from the direct output opens the elements 42 and 43 I. Thus, the system is allowed to switch to the mode of issuing certificates on the final data.

The structure of the codogram of the request for relevant certificates has the following form:

THE CODE THE CODE ID of the workstation from which data is requested Type of data requested:
- Or the number of sales made by a specific Aeroflot agency;
- Or the number of sales performed by all Aeroflot agencies.

The request code from the user's workstation enters the information input 21 of block 1, from where it enters the information inputs of register 40. At the same time, the input 24 receives a synchronizing pulse, which, having passed through element 42 AND, goes to the synchronizing input of register 40 and enters the request code into the register.

The request type code from the output 51 of block 1 goes to the input 74 of block 2 and then to the input of the decoder 61, which decrypts the type of user request, giving one of its outputs a high potential. For definiteness, we assume that a high potential is received at one input of element 65 I.

In parallel, the synchronizing pulse from the output of element 42 AND passes to the output 52 of block 1 and then goes to the input 75 of block 2, where it is delayed by element 71 for the duration of operation of register 40 and decoder 61, and then polls the states of elements 63-66 I.

Given the fact that only one element And will be open at one input, then, having passed this element And, the clock pulse, firstly, is fed to the read input of a fixed memory cell of the permanent storage device 60, where the base address of the memory cell assigned to the corresponding Agency whose reference data is requested.

The base address code from the output 77 of block 2 goes to the input 120 of block 4 and then, after passing the elements 118 OR groups, it is fed to the inputs of the registers 111, 112.

Secondly, the same read pulse passes through the element 70 OR of block 2 and is output to the input 95 of block 3 through the output 78 of block 2, where it is delayed by the delay element 89 for the duration of reading the contents of a fixed ROM cell.

Secondly, the same impulse after the delay by the element 91 for the time the agency’s base address is entered in the register 111 passes the OR element 84 and passes through the output 100 of the block 3 to the system output 33 and then to the input of the first server interrupt channel.

By this signal, the server goes to the subroutine for reading the contents of the database at the agency’s base address, which, from the output of register 111 of block 4, passes elements 113 AND groups opened by high potential from input 126, elements 117 OR groups, and is issued to address 31 of the system output.

The contents of the base address of the requested agency is read from the server database and through the information input 23 of the system it enters the information input of register 12, where it is entered by the server synchronization pulse from input 26, which also goes to input 46 of block 1, where it is delayed by element 44 while the data are being entered in the register 12, and then, passing the element 43 And, is output 53 as a synchronization pulse issuing a response to a user request.

This pulse arrives at the synchronization input 144 of block 5, the OR element 138 passes, and then rewrites the contents of the base address of the requested register agency 12 from the input 143 of block 5 through open elements 133 AND groups, elements 137 OR groups, and elements of one of the groups 134-136 to the workplace of the user who sent the request through one of the outputs 35-37 of the system.

For this, in parallel with the described process, the user workstation identifier code from the output 50 of block 1 is fed to the input 141 of block 5 and then to the inputs of the decoder 131, which opens one of the groups 134-136 corresponding to the selected user workstation.

The contents of the register 12 enters the input 143 of block 5 and then through the elements 133 AND groups, which are open at the second input with a high potential from the inverse output 81 of the trigger 62 of the block 2 supplied through the input 147 of the block 5, passes through the elements 137 of the OR group and then goes to inputs of groups of elements 134-136 I.

After issuing a certificate to the appropriate workstation, all the nodes and elements of the system are initialized with the same pulse from the output of the OR element 138, delayed by the time the data were issued (not shown in the drawing to simplify the drawing of the circuit for setting the nodes and blocks of the system in the drawing).

If the system receives a request of the second type, according to which the user asks for the total amount of sales by all agencies, then in this case the decoder 61 of block 1 opens element 66 And one input through which the synchronizing pulse from input 75 passes to the single input of trigger 62 and sets him to a single state.

In this case, the high potential from the output 80 of the block 2, coming to the input 146 of the block 5, the elements 132 And groups will be open, and the elements 133 And groups are closed. In this case, the output of block 11 through the input 142 of block 5 will be connected to the channel for issuing data to the workplace of the user who sent the request.

The synchronizing pulse from the output of element 66 AND block 2 is delayed by element 72 for the duration of the trigger 62 and the connection of the output of block 11 to the data output channel to the user's workstation and from the output 79 of block 2 goes to input 145 of block 5, where OR element 138 passes and to the synchronizing input of elements 134-136 AND groups, providing the issuance of the requested data.

Thus, the introduction of new nodes and blocks and new structural connections has significantly improved system performance by eliminating the time spent on pre-recording all the information received in the database, their subsequent search and processing.
