Reference numeral 20 denotes a plug provided at the end of the power supply line 18. [

The current sensor 110 provides the detected current to the relay terminal 140.

Contact type current sensor such as a non-contact type Hall element which detects current through a magnetic field generated by a current flowing through the power supply line 18 as a current detecting part, unlike the example shown in FIG.

The current detection processing unit 112 converts the signal output from the current sensor 110 into a digital signal and provides it to the relay terminal control unit 141.

The current detection processing unit 112 can be constructed so as to output current data detected at an interval of 0.2 seconds, for example, at a set period.

The reader 120 records the unique information including the model name of the refrigerator 10 to be inspected and reads the bar code 15 attached to the refrigerator 10 and provides the bar code 15 to the relay terminal 140 or the inspection terminal 160.

Unlike the illustrated example, the model name of the refrigerator 10 to be inspected may be recorded in a different form such as a QR code, and the reader 120 may be constructed correspondingly.

The relay terminal 140 is connected to the refrigerator control unit 11 that is mounted on the refrigerator 10 to be inspected and controls the refrigerator 10 to be inspected through a communication interface. The relay terminal 140 collects signals detected by the current detection unit And transmits it through the relay wireless communication unit 142.

The communication interface has a structure in which the first communication terminal 146 of the relay wire communication unit 145 provided in the relay terminal 140 and the second communication terminal 12 provided in the inspection subject refrigerator 10 can be connected to each other by wire Lt; / RTI >

The relay terminal 140 includes a relay terminal control section 141, a relay wireless communication section 142, a relay storage section 143, and a relay wire communication section 145.

The relay terminal control unit 141 temporarily stores the current information received from the current sensor 110 through the current detection processing unit 112 in the relay storage unit 143 and transmits the stored current information to the relay wireless communication unit 142 via the relay wireless communication unit 142. [ To be transmitted to the inspection terminal (160).

The relay wire communication unit 145 is connected to the refrigerator control unit 11 which is controlled by the relay terminal control unit 141 and controls the refrigerator 10 to perform wired communication.

The relay storage unit 143 records the current information detected by the relay terminal control unit 141 through the current sensor 110. [

The relay terminal 140 may be constructed as a relay module 140a which is integrally coupled to the current sensor 110 as shown in FIG.

On the other hand, the refrigerator control unit 11 provided in the refrigerator 10 performs the temperature control of the refrigerator or the freezing room through the control of the temperature controller 15 in accordance with the mode set in the operation unit (not shown).

Here, the temperature controller 15 refers to a known element such as a compressor which is operated for temperature control.

In the refrigerator storage unit 13, driving condition information corresponding to a supported mode and information on a set performance inspection item progress process are recorded.

In this refrigerator, when the refrigerator control unit 11 establishes a communication connection with the relay wire communication unit 145, the refrigerator control unit 11 communicates with the relay terminal 140 through the relay wire communication unit 145 and performs processing corresponding to the command information instructed .

The inspection terminal 160 performs wireless communication with the relay terminal 140 and performs a process for the inspection target refrigerator 10 through the relay terminal 140 in accordance with the performance inspection item progress process set in the refrigerator control unit 11 And judges whether or not the to-be-inspected refrigerator is to be inspected by using the current information supplied from the relay terminal 140 in correspondence with each of the performance check items to the inspection subject refrigerator 10.

The main communication unit 161 is controlled by the inspection control unit 163 and performs wireless communication with the relay terminal 140. [

The performance check item progress process and the reference supply current range value corresponding to the model names of various refrigerators produced are recorded in the database 165 so as to correspond to the model names.

The operation unit 166 can be used to set a supported function, and the display unit is controlled by the inspection control unit 163 to display the display information.

The inspection control unit 163 processes the performance inspection item progress process corresponding to the model read by the reader 120 to be transmitted through the relay terminal 140 so as to be performed through the refrigerator control unit 11 of the refrigerator 10, The signal for starting the inspection and ending the inspection is also transmitted so as to be transmitted in accordance with the processing process.

When the inspection is performed, the inspection control unit 163 compares the reference supply current range value recorded in the database 165 with the current detection information received from the relay terminal 140 so as to correspond to the inspection item, If it is out of the allowable range, it is judged to be defective and displayed through the display unit 167 exemplified as an example of the output apparatus.

The inspection control unit 163 transmits inspection end information to the relay terminal 140 when the inspection of the refrigerator 10 to be inspected is completed. In this case, the relay terminal 140 processes the current or power measurement data temporarily stored in the relay storage unit 143 to be deleted when the inspection completion signal is received.

Meanwhile, when the inspection terminal 160 is installed in a factory environment, it is preferable that the inspection terminal 160 is constructed as a computer supporting wireless communication.

Alternatively, if a request for repair is received from a user using a refrigerator, the inspector terminal may be built on a smartphone if a mechanic visiting the site is available.

Here, the smart phone communicates with the relay terminal 140 via Bluetooth, and a reading module for analyzing information such as a bar code and a QR code from the image recognized through the camera performs inspection control while performing a function of a reader The test execution module can be applied as an application program.
