Charging Terminal Offline Self-Help: Five Steps to Network and Heartbeat Troubleshooting

第一步:确认是否真离线

现场扫码测试支付,能下单说明设备在线,问题出在平台状态同步。

第二步:检查信号与 APN

进入工程模式查看信号强度,低于 -95dBm 时建议调整天线位置或加装外置天线。

第三步:核对心跳配置

心跳间隔建议 60 秒,超时判定 3 个周期;间隔过短会增加流量与功耗。

第四步:时间同步

设备时间偏差超过 5 分钟会导致 TLS 握手失败,表现为反复重连。

第五步:平台侧日志

比对平台上下线记录与设备本地日志,确认是否被误判踢下线。

若同一批次集中离线,优先排查运营商基站或平台接入层。
