mqtt_data_mock 2 | 将数据通过mqtt推送到服务端，支持windows及linux操作系统 3 | ![alt text](image.png) 4 | 5 | 主要功能： 6 | 1. 作为MQTT客户端，能让用户手动设置MQTT的IP 端口 用户名，并且能随机/手动输入客户端ID，默认MQTT版本5.0，连接超时时长10秒，keep alive 60秒。 7 | 2. 用户设置完后，可以点击连接按钮进行测试，测试通过后，进行连接。 8 | 3. 连接成功后，可以让用户手动选择txt文本进行导入，txt文本中包含多个点位信息，以英文逗号隔开，如: iot1,iot2,iot3 9 | 4. 导入完成后，给对应的MQTT发送消息，发送消息格式为JSON，内容如下： 10 | 5. 其中iot1、iot2等是从刚才的txt中取得，具体test1、test2，是固定的，需要从test1到test200，对应的数值随机，从-100到100，可以有两位小数。按每秒一次的频率进行数据发送。 11 | 6. 界面提供开始测试按钮，提供一个计数器，提示程序运行时间（时分秒格式） 12 | 13 | 推送数据格式： 14 | 15 | ``` 16 | { 17 | "iot1": [{ 18 | "test1": 3.8, 19 | "test2": 3.0, 20 | "test3": 3.0 21 | }], 22 | "iot2": [{ 23 | "test1": 3.8, 24 | "test2": 3.0, 25 | "test3": 3.0 26 | }], 27 | "iot3": [{ 28 | "test1": 3.8, 29 | "test2": 3.0, 30 | "test3": 3.0 31 | }] 32 | } 33 | ``` 34 | 35 | -------------------------------------------------------------------------------- /image.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/l56jq/mqtt_data_mock/785a988dac1cf3677a30f3ef3b3f8294127e6ffe/image.png -------------------------------------------------------------------------------- /linux/mqtt_config.txt: -------------------------------------------------------------------------------- 1 | mqtt_ip=127.0.0.1 2 | mqtt_port=1885 3 | mqtt_username=SlIPlC12txs7HGtTuGGb 4 | topic=v1/gateway/telemetry 5 | hours=2 -------------------------------------------------------------------------------- /linux/points.txt: -------------------------------------------------------------------------------- 1 | iotFBB3EFCEEDE7731940F69A28FF464238,iot4366A9C241C4390D3978CAAE24FF38D9,tr1B91844F369C244DB513C5319DA0A53D,trE6A0D4F85269AEF8A060F2555178C0CB,tr2EC3770F5D54426992AF325D472450F9,trF44DB7D6F6E6A744CE55CAC79E624ECF,tr0177A850B16E2BFE43665FB71B942E3B,trFC6427F18B5B1D3EF78BF8D93258BD12,tr5C61774F326F60E6888FEA96142E8EE7,tr0EBE19951ABD17820D0367EB3F58A601,tr75E7602EE519D1D3EEDA91E356A06E03,trECAEE2B306F3141AFC5070C1966E63C0,tr6FD769CB2A85399CF624D86F6F9E8821,tr4EC9AEC49DFC5955CC4AEF0CB9AB5890,trD8973D6DDD9F3D25F426E56CD41FA0DD,trDFC8614143BE9EDDD8618CE4B5737673,tr10194EF97DAEE06DCC62C62D7ADAAC3B,trCBB8FE42915BE1A5FF0AF837FF134AB5,tr4DDF6B5D20CB71D6D17F511736952B9B,tr52F47708D0B976101FA7CE7E373160A8,trEE8D1EBBA8696CE360D6E2515D97824A,tr300716BA41EFB2ACB2ABC2A81661BADC,trA7A7AEDDDDAA0B74136BD497977B5625,tr7A7DF9EE7976B16619F4BB44B436360C,tr9CE9B7D984211EB4E60CC5817494605D,tr1DD56F4DB5E2694F971A21DC8ADB2B0E,tr64AA063FDD5622CCD940E7350CBB1556,tr419EAAE45EDF75D75178DD60988A37BD,trBF1EE06D48F159A1D0570CC2EA2AE2B6,trFD9D53AD7F4A8140C8769E12450F1634,trB509CCC02945B4253E464ECD4AAD8024,trB741A493225618B24121A9F2AA924614,trF4D0FD01507DFA302DF879A8A2FD3938,trDB7D26D05DBE493AC221D1C3C09F7B1E,trA044A34B40C9BC59B0A125B0B102334C,trAA32184F89CDDEB6C7AEF432AE412DA9,trF46901CC5B0350CDF6B7A9122F290E58,tr9AF57402970886C12D2EC6EAC1C5CC5D,tr18FE8D6A55FBA6B0105F4509269CEFE8,tr4F5905D9CFD76005BC03B153645FA92C,tr965DA388921655B8B21598B4C5E70193,trFCCC85510A3A6B91028BF6B813008EE2,trC34ED6352DF5B147CF7046D0573E87F2,tr725D052C26F112F8E603F7AAE1C73D71,trF224728F9B5895E921F92662D603F7C0,trBABA876CDAAEDEF9676B2E4A8832A320,trA705602CC96AA1784CDAEAB59070606C,tr2A83E904F159732F3BA3EDE466123259,tr80DFEB1ADB31A649CD5A490F43C6B86F,trBB0C176A6E64CB82DE94AC2AA6EAF988 -------------------------------------------------------------------------------- /linux/send_data_linux.py: -------------------------------------------------------------------------------- 1 | import paho.mqtt.client as mqtt 2 | import random 3 | import time 4 | import json 5 | from datetime import datetime, timedelta 6 | import threading 7 | 8 | 9 | #
