7. Asset Service

Accessed via client.asset(). The core of the PlantPulse asset model — it manages the Site > Area > Line > Equipment hierarchy tree.

ID rules: The ASSET_ prefix is required. The type codes A/L/M determine the tree hierarchy. For details, see Domain ID Rules.

7.1 Method Summary​

MethodReturn TypeHTTPEndpoint
create(AssetRequestV5)AssetResponseV5 or nullPOST/api/v5/asset
update(asset_id, AssetRequestV5)AssetResponseV5 or nullPUT/api/v5/asset/{id}
delete(asset_id)booleanDELETE/api/v5/asset/{id}
get(asset_id)AssetResponseV5 or nullGET/api/v5/asset/{id}
list()List<AssetResponseV5>GET/api/v5/asset
exists(asset_id)booleanGET/api/v5/asset/{id}/exists

The Asset service focuses on simplified CRUD. For tree hierarchy queries, use the Path Service or client-side filtering (call list(), then filter on asset_type).

7.4 Usage Examples​

Creating an Area → Line → Equipment Tree​

import plantpulse.api.v5.dto.request.AssetRequestV5;

// 1) Area
AssetRequestV5 area = new AssetRequestV5();
area.setSite_id("SITE_DJ");
area.setParent_asset_id("SITE_DJ");
area.setAsset_id("ASSET_DJ_A_0001");
area.setAsset_name("조립구역");
area.setAsset_type("A");
client.asset().create(area);

// 2) Line
AssetRequestV5 line = new AssetRequestV5();
line.setSite_id("SITE_DJ");
line.setParent_asset_id("ASSET_DJ_A_0001");
line.setAsset_id("ASSET_DJ_L_0001");
line.setAsset_name("1번 조립 라인");
line.setAsset_type("L");
client.asset().create(line);

// 3) Equipment (CNC 머신)
AssetRequestV5 cnc = new AssetRequestV5();
cnc.setSite_id("SITE_DJ");
cnc.setParent_asset_id("ASSET_DJ_L_0001");
cnc.setAsset_id("ASSET_DJ_M_0001");
cnc.setAsset_name("CNC #1");
cnc.setAsset_type("M");
cnc.setTable_type("CNC");
cnc.setDescription("DMG MORI NLX-2500");
client.asset().create(cnc);

Retrieving a Single Asset​

import plantpulse.api.v5.dto.response.AssetResponseV5;

AssetResponseV5 cnc = client.asset().get("ASSET_DJ_M_0001");
if (cnc != null) {
    System.out.println(cnc.getAsset_name() + " (" + cnc.getAsset_type() + ")");
    System.out.println("부모: " + cnc.getParent_asset_id());
}

Full List + Filtering by Type​

V5 has no listByType method, so filter on the client side.

import java.util.List;
import java.util.stream.Collectors;

List<AssetResponseV5> all = client.asset().list();

// Equipment만
List<AssetResponseV5> equipments = all.stream()
        .filter(a -> "M".equals(a.getAsset_type()))
        .collect(Collectors.toList());

// 대전공장의 Line만
List<AssetResponseV5> djLines = all.stream()
        .filter(a -> "SITE_DJ".equals(a.getSite_id()))
        .filter(a -> "L".equals(a.getAsset_type()))
        .collect(Collectors.toList());

Rebuilding the Tree (Client Side)​

import java.util.HashMap;
import java.util.Map;
import java.util.List;
import java.util.ArrayList;

// asset_id 인덱스
Map<String, AssetResponseV5> byId = new HashMap<>();
for (AssetResponseV5 a : client.asset().list()) {
    byId.put(a.getAsset_id(), a);
}

// 부모-자식 매핑
Map<String, List<AssetResponseV5>> children = new HashMap<>();
for (AssetResponseV5 a : byId.values()) {
    children
        .computeIfAbsent(a.getParent_asset_id(), k -> new ArrayList<>())
        .add(a);
}

// 사이트(SITE_DJ) 산하 트리 출력
printTree(children, "SITE_DJ", 0);

static void printTree(Map<String, List<AssetResponseV5>> children, String id, int depth) {
    List<AssetResponseV5> kids = children.getOrDefault(id, List.of());
    for (AssetResponseV5 c : kids) {
        System.out.println("  ".repeat(depth) + c.getAsset_id() + " — " + c.getAsset_name());
        printTree(children, c.getAsset_id(), depth + 1);
    }
}

Updating an Asset​

AssetRequestV5 update = new AssetRequestV5();
update.setSite_id("SITE_DJ");
update.setParent_asset_id("ASSET_DJ_L_0001");
update.setAsset_id("ASSET_DJ_M_0001");
update.setAsset_name("CNC #1 (보수 후)");
update.setAsset_type("M");
update.setTable_type("CNC");
update.setDescription("2026-05-10 베어링 교체 완료");

client.asset().update("ASSET_DJ_M_0001", update);

Deleting an Asset​

⚠️ Before deleting an asset, you must first delete every Tag and child Asset connected to it.

boolean ok = client.asset().delete("ASSET_DJ_M_OLD");

7.5 Application Scenarios​

Scenario — Equipment List for a Site and Tag Count for Each​

String siteId = "SITE_DJ";

List<AssetResponseV5> equipments = client.asset().list().stream()
        .filter(a -> siteId.equals(a.getSite_id()))
        .filter(a -> "M".equals(a.getAsset_type()))
        .collect(Collectors.toList());

for (AssetResponseV5 eq : equipments) {
    long tagCount = client.tag().countByAsset(eq.getAsset_id());
    System.out.printf("%s — Tag %d개%n", eq.getAsset_name(), tagCount);
}

Scenario — Collecting OEE Dashboard Data per Line​

// 1) Line 목록
List<AssetResponseV5> lines = client.asset().list().stream()
        .filter(a -> "L".equals(a.getAsset_type()))
        .filter(a -> "SITE_DJ".equals(a.getSite_id()))
        .collect(Collectors.toList());

// 2) 각 Line 산하 Equipment 조회 → 자산 경로 → 작업지시 → KPI 집계
for (AssetResponseV5 line : lines) {
    List<AssetResponseV5> machines = client.asset().list().stream()
            .filter(a -> line.getAsset_id().equals(a.getParent_asset_id()))
            .collect(Collectors.toList());

    for (AssetResponseV5 m : machines) {
        long now = System.currentTimeMillis();
        // 현재 작업지시는 Order 서비스로 조회
        // ...
    }
}
