Abstract

PURPOSE:To make a tester more applicable, module more common, to automate a key operation and to shorten the read time of tester development by controlling software by means of a personal computer. CONSTITUTION:With an operation through a keyboard, a personal computer system part 1 transfers a processing program to a program storing memory part 3 through an interface part 2 from an external memory device and processed data to a data storing memory part 5, stores initialization data to a control part 4, and operates the control part 4. After a highway signal processing part 6 drops and stores arbitrary data on a highway, which is received from a reception circuit part 7, in the memory part 5 according to indications from the control part 4, it collates automatically drop answer data in the system part 1, and outputs the result as a processing message. After the time slot of the dropped data is converted, highway data is again transmitted from a transmission circuit part 8. The control part 4 is operated by a program stored in the storing memory part 3, and a variety of programs enable easily an optional highway test.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a highway test device used for testing the functional operation of a time division switch.

(Prior Art) Conventionally, this type of highway test equipment requires a dedicated circuit that has test functions tailored to the functions of each device under test.
Each time, we designed, manufactured, and adjusted the circuit, and tested each device under test using complicated key operations based on the operating instructions.

(Problems to be Solved by the Invention) The above-mentioned conventional highway test equipment of this type requires a dedicated circuit that has a test function tailored to the function of each device under test, and the test equipment must be developed each time. This led to long design and manufacturing lead times and high costs.
In addition, even during use, key operations are complicated and are performed very frequently, resulting in a large number of inspection steps and the possibility of operational errors.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by controlling software with a personal computer, to make test equipment more versatile, to standardize modules, to automate key operations, and to shorten the lead time for test equipment development. It is an object of the present invention to provide a program-controlled general-purpose highway test device configured to enable this.

(Means for Solving the Problems) A program-controlled general-purpose highway testing device according to the present invention includes a highway signal processing section, a program storage memory, a data storage memory, and a personal computer system section. It is something.

The highway signal processing unit is for processing various signals on the various highways of the electronic exchange, the program storage memory is for storing control programs for controlling the test 1), and the data storage memory is for It is used to store data used in testing.

The personal computer system unit controls the highway signal processing unit in a software manner using the control program read from the program storage memory and the nine data read from the data storage memory, and automatically tests various signals on various highways. be.

(Example) Next, the present invention will be explained with reference to the drawings. @Fig. 1 is a block diagram showing an example of a program-controlled general-purpose highway testing device according to the present invention. Only the main parts are shown.

In FIG. 1, the program-controlled general-purpose highway testing device according to the present invention includes a personal computer system unit 1 equipped with a human-machine interface function.
, a twin interface unit 2 for interfacing between the personal computer and the test equipment, a program storage memory unit 3, a control unit 4 for controlling the entire test equipment, a data storage memory unit 6, and a a highway signal processing section 6 for processing data on the highway; a receiving circuit section 7 for receiving data on the highway;
It is configured with a transmitting circuit section 8 for transmitting data.

The operation of the program-controlled general-purpose highway testing apparatus according to the present invention will be explained in order below with reference to FIG.

In FIG. 1, the partial computer system section 1
By operating the keyboard, the processing program is transferred to the 10-gram storage memory section 3 through the external memory of the personal computer system section 1 or the Rahersonal computer interface section 2. At this time, the processing data is also transferred to the data storage memory section 5, and by giving a program startup instruction from the personal computer system section 1, initial setting data is stored in the control section 4, and the control section 4 is operated by software processing.

The highway signal processing section 6 starts multiple operations in response to instructions from the control section 4, drops arbitrary data on the highway received from the receiving circuit section 7, stores it in the data storage memory section 5, and then outputs it to the personal computer system. The personal computer system section 1 automatically collates the correct answer data for drop scheduled in advance in the section 1, and outputs the result as a processed message. After converting the time slot of the dropped data, the data is sent out from the sending circuit unit 8 to the highway again. At the same time, it is also possible to store the transmission data in the personal computer system section 1 or the data storage memory section 6, insert it into a designated time slot on the highway, and transmit it.

The control section 4 operates according to the program stored in the program storage memory section 3, and can arbitrarily send instructions for inserting, dropping, and time slot conversion to the highway signal processing section 6. The control unit 4 has a data check function and also has a timer function that generates each of the 11 timings.

Therefore, any highway test can be performed very easily using various programs prepared in the personal computer system section 1.

(Effects of the Invention) As explained above, the present invention enables the reduction of design and manufacturing lead times by controlling the functional processing of a program-controlled general-purpose highway testing device using a program.
Moreover, the process can be reduced, and the operation can be automated using a personal computer, reducing the number of man-hours required for operation.

Another advantage is that by changing the program, it can be easily used for testing other devices.
