Due　to　the　safety　requirements　of　industrial　sites　and　the　closed　characteristics　of　control　systems,　intelligent　algorithms　with　off-line　research　mode　are　difficult　to　verify　online　in　municipal　solid　waste　incineration　(MSWI)　process.　In　addition,　the　existing　laboratory　simulation　platform　is　difficult　to　simulate　the　industrial　reality　of　domain　expertsíntelligent　perception,　cognition,　decision-making　and　control　based　on　multi-modal　data.　In　view　of　the　above　problems,　first,　on　the　basis　of　summarizing　the　research　status　and　challenge　of　the　existing　simulation　platform　for　industrial　process,　the　requirements　of　testing　and　verification　platform　for　MSWI　process　are　described.　Furthermore,　the　modular　hardware-in-loop　platform　for　intelligent　algorithm　testing　and　verification　is　proposed　and　constructed,　which　is　composed　of　multi-modal　historical　data-driven　system,　security　isolation　and　optimal　control　system,　and　multi-input　and　multi-output　loop　control　system.　Then,　the　platform　hardware　construction,　industrial　software　development,　simulation　function　realization　and　typical　scene　verification　are　completed　in　the　laboratory　environment,　and　some　modules　are　transplanted　to　the　industrial　site　for　application.　Finally,　the　research　direction　of　the　modular　hardware-in-loop　platform　is　summaried　and　prospected.　©　2024　Science　Press.　All　rights　reserved.
