In addition, in each drawing shown in the embodiment of the present invention, each component may be illustrated in a somewhat enlarged or reduced manner in consideration of convenience of description.

Hereinafter, a method for installing software on a plurality of devices in the present invention will be described.

1 is a view showing a plurality of equipment connected to a server according to an embodiment of the present invention, FIGS. 2 and 3 are flowcharts showing a method of installing software in a plurality of equipment according to an embodiment of the present invention, FIG. 4 is a diagram showing a state in which a software hash value and an identification number are uploaded to a block of a server according to an embodiment of the present invention.

As shown in FIG. 1 , the server 10 and the plurality of devices 50 according to an embodiment of the present invention may be connected based on a block chain network. Here, the equipment refers to the SMT equipment. For example, the plurality of SMT equipment may include an automatic inspection equipment AOI (Auto Optical Inspector), a chip mounter, a sensor, a valve, a screen printer, and the like.

In addition, the plurality of equipment 50 may mean a plurality of SMT lines of a factory or may be regarded as a plurality of SMT equipment included in several factories.

For example, the first equipment 110 and the second equipment 120 of FIG. 1 are equipment included in the first factory, and the third equipment 210 and the fourth equipment 220 are included in the second factory. equipment, the fourth equipment 310 and the fifth equipment 320 may be equipment included in the third factory, and the sixth equipment 410 and the seventh equipment 420 may be equipment included in the fourth factory. .

Blockchain refers to a distributed data storage technology that transparently records details that anyone can view, and replicates and stores them on multiple computers.

Accordingly, each of the server 10 and the plurality of devices 50 connected on the block chain network is formed as a node and may include a block that is a storage on the block chain. Accordingly, when data is recorded in any one of the plurality of blocks, the server 10 and the plurality of devices 50 may mutually share and view the data.

For example, when a software installation file is recorded in a block in the server 10 or a place where a software installation file is stored is recorded, a plurality of equipment 50 including the server 10 is recorded in the block of the server 10 . It can recognize and share the software installation file or the storage location of the software installation file. Hereinafter, the software installation file will be described as software.

In addition, a smart contract code may be recorded in each block. The smart contract code is a code formed so that, when a specific condition is satisfied, a specific operation can be performed regardless of the command of the user or the server 10 . For example, when software is recorded on a block of the server 10, at least one device may automatically install the software according to a specific condition satisfaction and a smart contract code.

According to the above, the method of installing software on a plurality of equipment 50 according to an embodiment of the present invention includes an upload step (S100), an identification step (S200), a hash value determination step (S300), and an installation step (S400) may include.

The upload step ( S100 ) is a step in which the software provider uploads the software, the software hash value and the identification number to the block of the server and uploads it to the block chain network. Specifically, as the software, the software hash value and the identification number are uploaded to the block of the server, they are recorded in the blockchain network so that a plurality of devices 50 can recognize and share the software, the software hash value and the identification number.

Here, the software hash value included in the block of the server may be formed as an initial value obtained by hashing the software.

xyz and abc written next to each device in FIG. 4 represent a hash value derived by hashing the software, and a number written next to each device represents an identification number of each device.

The identification step (S200) compares the identification number of the plurality of equipment 50 with the identification number included in the block of the server and includes an identification number that matches the identification number included in the block of the server among the plurality of equipment 50 Identifying at least one device.

When the software provider wants to install the software on only at least one device, the server block may include the identification number of the at least one device. Accordingly, the identification number recorded in the server block may be formed as an identification number of at least one device among a plurality of devices connected to the block chain network.

For example, as shown in FIG. 4 , there is no need to install/execute software only on the fifth equipment 310 having an identification number 3-1 and a sixth equipment 320 having an identification number 3-2 among a plurality of equipment. If there is, it may include 3-1 and 3-2 identification numbers in the block of the server. On the other hand, all identification numbers described in the drawings are described for the sake of explanation and may be described with various numbers.

The hash value determination step ( S300 ) is a step of determining whether the software is normal by comparing the hash value derived by hashing the software with the software hash value recorded in the block of the server by the plurality of devices 50 , respectively.

As described above, an identification number and a software hash value may be stored in the block of the server.

In addition, when a software hash value is written in a block according to the characteristics of the block chain network, the software hash value is shared among multiple devices, so all devices compare the software hash value with the hash value derived from the software to determine whether the software is normal or not. can judge

Also, the hash value determination step S300 may further include a ratio calculation step S310 and a normal determination step S320 as shown in FIG. 3 .

The ratio calculation step (S310) is a step of calculating a hash value agreement ratio by comparing the software hash value recorded in the block of the server with the hash value derived from the software by each device, and the normal determination step (S320) is the hash value agreement ratio It is a step of determining whether the software is normal or not by comparing it with the preset ratio.

In the normal determination step ( S320 ), when the hash value matching ratio is higher than the preset ratio, the software may be determined to be normal, and if the hash value matching ratio is smaller than the preset ratio, the software may be determined to be abnormal. Here, the preset ratio may be set to 60% of the total number of devices connected to the blockchain network, but is not limited thereto. For example, it can be formed by Pow, Pos, etc., which are blockchain consensus algorithms.

For example, as shown in FIG. 4 , the software hash value of the server block is xyz, and the device that derives the xyz hash value among a plurality of devices records the match determination in its own block and shares it with all devices, and the abc hash The device that derives the value records the error determination in its block and can be shared with all devices, so that the hash value matching rate can be grasped from all devices (nodes).

At this time, as shown in FIG. 4 , if the match determination is higher than a preset ratio, the software may be determined to be normal.

In the installation step (S400), when the software is normal and the hash value derived from the identified at least one device matches the software hash value, the identified at least one device is a step of installing the software.

For example, as shown in FIG. 4 , the hash values of the identification numbers 3-1 and 3-2 devices 310 and 320 and the hash values of the software match, so the identification numbers 3-1 and 3-2 devices 310 , 320) may execute or install software according to the smart contract code.

In addition, the equipment deriving a hash value that does not match the software hash value in the installation step (S400) may be determined as an error. In this case, it may be determined that the derived hash value has been tampered with maliciously or according to a setting error.

For example, since the hash values derived from the 4-1 device and 4-2 device in FIG. 4 do not match the software hash value of the server block, the ID 4-1 device and 4-2 device are set as equipment errors can be That is, it can be determined that the 4-1 device and the 4-2 device have artificially changed hash values due to hacking.

In addition, in the installation step ( S400 ), each device can record whether software is installed, a self-identification number, etc. on a block and upload and share it on the block chain network. Accordingly, the server 10 can determine whether the software is being installed on the correct equipment.

On the other hand, in the method of installing software on a plurality of equipment according to an embodiment of the present invention, the equipment error step (S500) may be further included.

In the equipment error step (S500), when the software is determined to be abnormal, and the hash value derived from the at least one equipment identified in the identification step (S200) matches the abnormal software hash value, the identified at least one equipment is an error It is the judgment stage.

In addition, the equipment determined to be an error in the equipment error step (S500) displays a warning that there is an error in the equipment according to the smart contract code recorded on the block, blocks the network, and automatically performs virus check and treatment tasks can do. In addition, when a virus is detected and treated, the device that was determined to be an error can be re-contacted to the network according to the smart contract code. However, if treatment is not possible, the equipment may additionally display an error to inform the user. Here, the warning display and the error display may be notified to the user through a speaker or display provided in the equipment or may be notified to the user through at least one LED. When at least one LED is used, the LEDs may be set to generate light of different colors according to each display.

In addition, the operation according to the smart contract as described above may be performed in at least one device determined as an error in the installation step (S400).

For example, referring to FIG. 4 , at least one of the devices 401 and 402 is maliciously hacked to install the abnormal software, and the hacked device may determine an abc hash value derived from the abnormal software as a match.

However, unless more than half of other devices connected to the blockchain network are maliciously hacked, the installation of abnormal software on at least one hacked device may be disabled as other devices judge abnormal software as abnormal.

Accordingly, the 4-1, 4-2, and 4-3 devices 410 and 420 from which the hash value derived from the abnormal software is derived may be determined to be an equipment error in the equipment error step S500.

Accordingly, the 4-1, 4-2, and 4-3 devices 410 and 420 may automatically perform tasks such as displaying a warning, blocking the network, checking for viruses, and treating viruses according to the smart contract.

As such, the method of installing software on a plurality of equipment according to an embodiment of the present invention can efficiently install software on a plurality of equipment through a block chain network, and determines whether the software is normal by determining the hash value matching ratio. Software can be safely installed on multiple devices.

In addition, since the server and the plurality of devices according to an embodiment of the present invention are connected by a block chain network, the server 10 can efficiently collect the states and situations of the plurality of devices 50 .

For example, since each device can be automatically shared with the server by recording data that periodically records its state and status by a smart contract code in a block, the server 10 can use a plurality of devices 50 through this. It is possible to recognize the overall situation by efficiently collecting the data of
