To　ensure　the　personnel　safety　in　tunnel　construction,　we　researched　the　vault　sink　automatic　measurement　technology,　surrounding　rock　displacement　automatic　measurement　technology,　the　video　surveillance　technology　and　the　wireless　position　management　technology　of　the　personnel　into　the　tunnel.　The　techniques　and　keys　are　discussed.　The　measurement　data　of　these　techniques　combined　to　a　unified　software　platform.　Combined　with　the　wireless　communication　network　to　realize　the　mobile　phone　short　message　alarm,　using　the　computer　intemet　to　realize　the　remote　query　and　control,　we　achieve　the　automation,　informatization,　network　and　intelligent　management　to　ensure　the　safety　of　the　tunnel　construction
