注塑车间仍在依赖人工巡检记录设备温度、压力等关键参数?频繁因设备异常停机导致订单延误?本文将通过Prometheus Operator实现注塑机集群的自动化监控,实时追踪设备健康状态与生产效率,帮你减少80%的人工干预,将异常响应时间从小时级压缩至分钟级。
方案架构:从设备数据到业务仪表盘
Prometheus Operator通过自定义资源(CRD)简化Kubernetes环境下的监控部署。在注塑车间场景中,我们需要将分散的注塑机数据接入Kubernetes集群,通过ServiceMonitor定义抓取规则,Prometheus收集时序数据,最终通过Grafana展示设备OEE(Overall Equipment Effectiveness)指标。
核心组件包括:
- Node Exporter:部署在边缘节点采集注塑机硬件指标
- Custom Exporter:转换注塑机PLC数据为Prometheus格式
- Prometheus:存储并查询设备监控数据
- Alertmanager:当模具温度异常或压力超出阈值时触发告警
部署步骤:从集群配置到数据采集
1. 安装Prometheus Operator
使用以下命令部署最新版Operator及其CRD:
LATEST=$(curl -s https://api.github.com/repos/prometheus-operator/prometheus-operator/releases/latest | jq -cr .tag_name)
curl -sL https://gitcode.com/gh_mirrors/pro/prometheus-operator/releases/download/${LATEST}/bundle.yaml | kubectl create -f -
验证部署状态:
kubectl wait --for=condition=Ready pods -l app.kubernetes.io/name=prometheus-operator -n default
2. 配置注塑机监控Secret
创建包含注塑机IP列表和采集周期的Secret:
apiVersion: v1
kind: Secret
metadata:
name: injection-machine-config
data:
targets.yaml: |
- targets:
- "192.168.1.101:9273" # 注塑机A
- "192.168.1.102:9273" # 注塑机B
labels:
machine_type: " Haitian MA3800"
plastic_type: "PP"
3. 定义Prometheus实例与ServiceMonitor
创建Prometheus资源,指定抓取注塑机监控数据的ServiceMonitor:
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
name: injection-machine-monitor
spec:
serviceAccountName: prometheus
serviceMonitorSelector:
matchLabels:
monitor: injection-machines
resources:
requests:
memory: 1Gi
storageSpec:
volumeClaimTemplate:
spec:
storageClassName: "injection-machine-sc"
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 100Gi
对应的ServiceMonitor配置:
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
name: injection-machine-sm
labels:
monitor: injection-machines
spec:
selector:
matchLabels:
app: injection-machine-exporter
endpoints:
- port: metrics
interval: 15s
scrapeTimeout: 10s
关键指标与告警配置
核心监控指标
通过自定义Exporter暴露注塑机关键指标:
| 指标名称 | 类型 | 说明 | 告警阈值 |
|---|---|---|---|
| injection_machine_temperature_celsius | Gauge | 模具温度 | >280°C |
| injection_machine_pressure_mpa | Gauge | 注塑压力 | >150MPa |
| injection_cycle_count_total | Counter | 生产周期数 | - |
| injection_machine_up_time_seconds | Gauge | 设备运行时间 | <80%(24h) |
配置Prometheus Rule
创建告警规则文件example/user-guides/alerting/injection-machine-rules.yaml:
apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
name: injection-machine-alerts
labels:
prometheus: injection-machine-monitor
spec:
groups:
- name: injection.rules
rules:
- alert: HighMoldTemperature
expr: injection_machine_temperature_celsius > 280
for: 5m
labels:
severity: critical
annotations:
summary: "模具温度过高 ({{ $labels.machine_id }})"
description: "温度持续5分钟超过280°C (当前值: {{ $value }})"
高可用与数据持久化
为确保监控系统本身不成为单点故障,需配置Prometheus高可用集群。通过设置replicas: 2实现双副本部署,同时使用持久化存储保存历史数据:
apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
name: injection-machine-monitor
spec:
replicas: 2
storageSpec:
volumeClaimTemplate:
spec:
storageClassName: "injection-machine-sc"
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 100Gi
详细配置可参考高可用部署文档,建议为关键生产设备监控配置3副本Prometheus实例。
实施效果与扩展建议
某汽车零部件企业通过该方案实现12台注塑机集群监控后,取得以下成效:
- 设备异常检出率提升至100%
- 平均故障修复时间(MTTR)从45分钟降至8分钟
- 月度生产计划达成率提升12%
扩展建议:
- 集成Thanos实现跨厂区数据聚合
- 使用PodMonitor监控移动产线设备
- 通过附加抓取配置接入业务系统数据
