Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a testing method for a data aggregation system such as a telephone voting system using a testing device that automatically transmits voting data in place of a telephone subscriber.

A telephone voting system in which a horse racing telephone voting subscriber calls the center using a touch-tone telephone and transmits voting data, etc. by pressing a button in response to a voice response from the center, usually involves a large number of subscribers calling the center at the same time. Since this is expected, the configuration is generally such that about 256 call lines can be formed at the same time using the center's representative telephone number. For this reason, check the functionality of each part of the center side equipment (load test)
In this case, for example, it is necessary to mobilize more than 100 people at the same time to actually input mock voting data from telephones, which has the disadvantage of making it difficult to secure manpower and increasing personnel costs. The present invention aims to improve this point and enable better functional testing than was previously possible with a small number of personnel.

The test method of the data aggregation system of the present invention includes a voting data input device, a network control device having a plurality of input lines,
a processing device that identifies and totals voting data input from the input device; a network control device receives a call from the input device and connects the input device and the processing device; In a data aggregation system that causes a processing device to aggregate data, a voting data generation source that generates a plurality of voting data and a network control device that generates data specifying a line to which the processing device should be connected. The present invention is characterized in that a test device having a connection line specification data generation source is provided, and the processing unit and the data generation source are repeatedly connected via the line specified by the generated connection line specification data to conduct aggregation tests. However, this will be explained in detail below with reference to the illustrated embodiment. FIG. 1 is a block diagram of a telephone voting system to which the data aggregation system testing method of the present invention is applied, and 1 is a pushphone simulator (PPS) according to the present invention.

Reference numeral 2 denotes a network control unit (NCU), which is placed after the central telephone exchange (not shown), and although only one is shown in the figure, in reality, it is provided for lines. Subscribers' touch-tone telephones are connected to multiple network controllers 2 through public lines and exchanges.
Connect to an empty one and enter voting data, etc. The simulator 1 is connected to the line input terminal of the network control unit (NCU) 2, and has the function of automatically calling the center in place of the subscriber's telephone and sequentially transmitting random voting data in accordance with the voice response from the center. has.

After the NCU 2, the center has a receiver/register adapter 3 (this is called a line control device together with the NCU 2),
central processing unit (CPU) voice response unit (VRU) 5;
and a voice drum (VDU) 6, a voice response device 5
The response voice from drum 6 selected and edited by NC
It is sent back to simulator 1 (subscriber telephone in case of actual operation) through U2. The receiver (REC) of device 3 converts the received multi-frequency signal (bush phone signal) into a 7-bit digital signal, the register (REG) temporarily stores the digital signal, and the adapter (ADP) converts the received multi-frequency signal (bush phone signal) into a 7-bit digital signal.
It has the function of an interface between the EG and the CPU, and converts the output of the register REG into an electronic signal suitable for the CPU.
Table 1 shows multi-frequency signals (combination matrix of high and low frequencies) normally used in bush phones, for example, the number Rl
The signals generated when the push button marked J is pressed are H side C1 (frequency 1209Hz) and L4IlARl (frequency 697H).
z) consists of a composite wave.

If 1 in FIG. 1 is replaced with an ordinary bushphone telephone, it becomes equivalent to the telephone voting system in operation, and by inputting voting data from the telephone, a load test of the center device can be performed.

This is the method used in the manual test described above. It should be noted that all the components other than the CPU 4 in the figure are provided for line support, and if a dual system is adopted, there will be two CPUs 4. To give an overview of actual telephone voting, when the calling telephone is connected to the NCU 2 through the public line and exchange, the CPU 4 detects this and activates the voice response device 5, and from the drum 6, for example, 1. XX This is a telephone voting station. A voice response saying "Please enter your subscriber number and PIN number" will be sent back to the telephone. Table 2 is an example of voting data sent by a subscriber from a telephone. According to the above-mentioned response voice, the subscriber selects NO. The contents of Rll...11J are sent, and when it is confirmed that the voter is a telephone voting subscriber, the center returns a response voice asking for the name of the racetrack.

Voters tell them the name of the venue, and once the center confirms it, they are encouraged to vote. Voters will then be asked to enter their voting details, including race number, single win or consecutive wins, group number indicating prediction of first and second place,
Enter the number of votes. As shown in Table 2 below, before each button operation, a confirmation or instruction response voice is sent back from the center, and the buttons are operated accordingly. One round of voting ends with the operation of IO. A pound mark # indicates a break in the message. Also, although not shown, NO. Incoming signal Ci and dummy signal DMY are placed before NO. A return signal RET is input after lO. In conventional load tests, the operations simulating the above are performed manually, making long tests extremely troublesome.Also, it is difficult to conduct tests that simulate situations where calls occur frequently, such as immediately before the start of a race. It has the disadvantage of requiring a large number of personnel.

The pushphone simulator 1 of the present invention solves this problem, and a specific example thereof is shown in FIG.

In the figure, 11 is a panel unit (PNL), 12 is an input switch group (SWU) of the panel unit, 13 is a basic clock generator (CLK), and 14 is a memory address counter (
MEAD), 15 is a memory (MEM), 16 is a bush phone signal generator (PPG), 17 is an external connection terminal connected to the NCU 2, 18 is a control part, 19 is a traffic and random pattern generator, 20 is a paris The error check section 21 is a # signal detection section. Simulator 1
is a test device that automatically and repeatedly performs a voting operation performed by a subscriber using a telephone, randomly changing the contents of the vote. The frequency of the output clock of the clock generator 13 determines the input speed of voting data, and this clock frequency can be changed by operating the input switch group 12. Also, the pause time between each vote performed by this simulator is determined by the generator 19.
The output signal becomes random. From terminal 17 to NCU
The signals output to the 2nd side include an incoming signal CI and voting data PPO, which are equivalent to the signals generated when the handset is picked up.
Conversely, the signal arriving at the terminal 17 from the NCU 2 includes a sound output signal FVO indicating that a response voice is being output. Signal FVO is on while the VRU is outputting audio, and the simulator sends out the next signal when signal FVO is off. Specifically, while the signal FVO is on, the address counter of the memory is prohibited from incrementing, and when the signal is turned off, it starts incrementing, and stops the incrementing when the # mark at the end of the message is detected. The memory 15 is a P-ROM, and various messages shown in Table 2 (more types of voting contents are prepared) are written therein.

Since the output of this simulator is a bush phone signal, the memory 15 also includes a data bush phone signal conversion table shown in Table 3 below to obtain the bush phone signal.
In the same table, 8S8A4-8C... is a MEM address, and each address has the bush phone signal 1 shown in Table 1,
2, 3, etc. are stored. Note that in Table 3, tone output Ci is a calling indicator signal, and
indicates the line of the network control device 2 to be connected. 2
Tone outputs 1, 2, 3, which are 8-bit signals...
* is added to the generator 16 and becomes an analog bush phone multi-frequency signal.

The contents of the memory 15 are accessed using the count value of the counter 14 as an address. Although the counter 14 itself only counts up the output clock of the clock generator 13, the generator 19 randomly sets the preset value of the counter 14. Specifically, the generator 19 has a built-in counter that repeats counting from 0 to 15, reads this at a random time, and sets the count value at that time in the address counter 14. The generator 19 also controls the counting operation of the counter 14 by turning on and off the clock input from the clock generator 13 to the counter 14, thereby randomizing the time points at which votes occur. In this way, the voting contents in Table 2 are changed randomly, and such voting occurs randomly. This operation will be further explained with reference to FIG. First, when the simulator 1 (PPSl) is activated from the panel 11, the clock source 13 is activated.

In this example, the count value of the memory address counter 14 is initially ♂
is set to . Therefore, the memory MEMl5 is

111r is output. This signal is converted into a tone signal by the signal transmitter 16 and supplied to the network control device 2 via the external connection terminal 17. When the incoming call signal CI is transmitted using the above automatic dialing function, the center CPU 4 detects this and dials the number from the drum 6 to the number shown in Table 2. A response voice instructing the contents of l is sent back. Since the simulator 1 does not have the function of identifying audio content, this is simply an on/off signal F.
When the signal FVO is recognized by VO and turns off, the control unit 18 causes the counter 14 to count and calculates the counted value as r in Table 2.
l! 0.1 data storage address, and the data is stored in the memory 15. Read the data of 1. After that, as mentioned above, there is a response signal such as ``Please enter the name of the first place'', and in response to this, the control unit 1
8 sets the counter 14 to the next value, that is, No. 8 in Table 2. 2 data storage address. The venue name is now read from the memory 15, and the next step is voting. At this time, the generator 19 operates to make the count value of the counter 14 irregular, so that votes of various contents occur. One RMEM address in FIG. 3 is the counted value of the counter 14, which starts counting when the signal FVO is turned off, stops it when the output of the # mark detection section 21 is output, and remotely stops this operation when the signal RET is detected to end this operation. Repeat until Simulator 1
As described above, the traffic generation unit 19 determines the timing at which the next vote is to be performed. Note that the parity error check unit 20 uses the 8-bit output P-C1 of the memory 15 (Table 3).
is monitored by its parity bit P, and if an error occurs, the counter 14 is stopped through the control section 18, and a lamp on the panel section 11 is lit to indicate the fact. In testing the entire telephone voting system, it is preferable that simulators 1 be used, for example, in a number of about 60 to 70% of the total number of lines, and the rest are operated by testers as actual bush phones.

In this way, although the simulator 1 does not have speech recognition ability, it can supplement this ability. Also, this method requires far fewer personnel than distributing testers throughout the test. Moreover, since the pseudo telephone voting by the simulator 1 is automatically repeated and carried out at high speed as necessary, it is possible to easily conduct a test over one day and night, for example. Note that the CPU 4 sequentially determines whether the test results are good or bad. Further, in the above embodiment, the voting data generation source that generates a plurality of voting data is composed of a clock source 13, a memory address counter 5, and a push button signal generation section 16, and a connection line designation The data generation source also includes a clock source 13, a memory address counter 14, a memory address 5, and a push button signal generation section 16.
The explanation has been made based on a configuration in which the contents are shared except that the storage address of the memory 15 is different. As described above, according to the present invention, since data aggregation is simulated in a pseudo manner, even in a system where an input device is connected to a center via an NCU many times, the functions on the center side can be efficiently and sufficiently performed by a small number of people. It has the advantage of being testable.
