Abstract

One or more embodiments provide a heterogeneous test equipment interfacing apparatus. The heterogeneous test equipment interfacing apparatus includes a plurality of data intermediate apparatuses connected to a plurality of environment test chambers; and at least one computer apparatus interoperating with the plurality of data intermediate apparatuses. Each of the plurality of data intermediate apparatuses is configured to convert an electric signal received from at least one environment test chamber interoperating with a corresponding data intermediate apparatus from among the plurality of environment test chambers into a data signal based on an SNMP protocol, output the data signal and, output a control signal for controlling the at least one environment test chamber interoperating with a corresponding data intermediate apparatus according to an operation control instruction received from the at least one computer apparatus.

First claim

What is claimed is:

1. A heterogeneous test equipment interfacing apparatus comprising:
a plurality of data intermediate apparatuses connected to a plurality of environment test chambers, wherein each of the plurality of data intermediate apparatuses converts an electric signal received from at least one environment test chamber interoperating with a corresponding data intermediate apparatus from among the plurality of environment test chambers into a data signal based on a Simple Network Management Protocol (SNMP) and output the data signal; and
at least one computer apparatus interoperating with the plurality of data intermediate apparatuses,
wherein each of the plurality of data intermediate apparatuses outputs a control signal for controlling the at least one environment test chamber interoperating with a corresponding data intermediate apparatus according to an operation control instruction received from the at least one computer apparatus,
wherein the at least one computer apparatus executes:
a plurality of commonization daemons, which are executable as a single process on a single computer or executable on multiple computers in correspondence to the plurality of data intermediate apparatuses;
an abstract interface implementing an input interface of a corresponding commonization daemon from among the plurality of commonization daemons to receive the data signal from a corresponding data intermediate apparatus from among the plurality of data intermediate apparatuses and to implement a modified interface according to heterogeneous digital interfaces; and
a common interface implementing an output interface of a commonization daemon from among the plurality of commonization daemons, generating chamber data of the environment test chamber according to the data signal received from the abstract interface as common data in a JavaScript Object Notation (JSON) format, and transmitting the common data to a storage interface and a distribution interface.

2. The heterogeneous test equipment interfacing apparatus of claim 1 ,
wherein the common interface
determines whether the common data is first common data in an Structured Query Language (SQL)/JSON format or second common data in an User Datagram Protocol (UDP)/JSON format,
by interoperating with an environment test big data DataBase (DB) and an environment test post-analysis application by using the first common data in the SQL/JSON format, stores the first common data in the environment test big data DB through the storage interface, and,
by interoperating with environment test monitoring applications by using the second common data in the UDP/JSON format, transmits the second common data to the environment test monitoring application.

3. The heterogeneous test equipment interfacing apparatus of claim 1 , wherein the plurality of environment test chambers connected to the plurality of data intermediate apparatuses are weapon system environment test chambers having analog interfaces, and at least some of the environment test chambers are of different types.

4. The heterogeneous test equipment interfacing apparatus of claim 3 , wherein at least some of the plurality of commonization daemons are of different types in correspondence to the plurality of environment test chambers.

5. The heterogeneous test equipment interfacing apparatus of claim 4 , wherein some of the plurality of commonization daemons are directly coupled to the environment test chambers through digital interfaces without a data intermediate apparatus.

6. The heterogeneous test equipment interfacing apparatus of claim 1 , wherein each of the data intermediate apparatuses comprises:
a plurality of input terminals connected to the at least one environment test chamber interoperating with;
a plurality of input relays converting electric signals received from the plurality of input terminals into signals of a pre-set voltage level;
a Micro Controller Unit (MCU) converting the signals of the pre-set voltage level into the data signal based on the SNMP protocol; and
a communication unit outputting the data signal.

7. The heterogeneous test equipment interfacing apparatus of claim 6 , wherein each of the data intermediate apparatuses comprises:
a plurality of output relays converting a control signal output from the MCU into a direct current (DC) control signal; and
a plurality of output terminals outputting the DC control signal to the at least one environment test chamber interoperating with.

8. The heterogeneous test equipment interfacing apparatus of claim 7 , wherein each of the data intermediate apparatuses further comprises
an alternating current (AC) output relay converting the DC control signal into an AC control signal,
wherein the AC control signal is output to the at least one environment test chamber interoperating with through the plurality of output terminals.

9. The heterogeneous test equipment interfacing apparatus of claim 7 , wherein the MCU comprises General Purpose Inputs (GPIs) and General Purpose Outputs (GPOs) respectively corresponding to the plurality of input terminals and the plurality of output terminals and stores input port information and output port information for mapping the GPIs and the GPOs to points of the at least one environment test chamber interoperating with.

10. The heterogeneous test equipment interfacing apparatus of claim 6 , wherein the MCU executes an SNMP manager based on a common Management Information Base (MIB).

11. An environment test system comprising:
a plurality of environment test chambers, wherein at least some of the plurality of environment test chambers are of different types;
a heterogeneous test equipment interfacing apparatus of claim 1 connected to the plurality of environment test chambers; and
an operating computer apparatus receiving an operation control of a user and, according to the operation control of the user, execute a management application providing operation control instructions to the heterogeneous test equipment interfacing apparatus to control the plurality of environment test chambers.

12. The environment test system of claim 11 , wherein the operating computer apparatus comprises:
an operation pattern big data storage storing operation control data in which operation controls received from the user are recorded; and
a machine learning model trained to determine whether an operation control of the user corresponds to a normal pattern by using the operation control data.

13. The environment test system of claim 12 , wherein the management application inquires an operation control of the user to the machine learning model, receive pattern information from the machine learning model, and, when the pattern information indicates an abnormal pattern, output a warning sign.

14. The environment test system of claim 12 , wherein the machine learning model is a decision tree model.
