11. a kind of monitoring method, the open and-shut mode for monitoring the casing with multiple leaf door, it is characterised in that
Comprise the following steps：
One photoswitch sensor is set on every Yishanmen of casing, and the photoswitch sensor includes light path
Blocking-up type photoswitch sensor and reflection-type photoswitch sensor；The quantity of the reflection-type photoswitch sensor
For 1, light path distributor and the reflection-type photoswitch sensor are sensed by the light path blocking-up type photoswitch
Device is connected, and is connected in series between the light path blocking-up type photoswitch sensor；
The monitoring optical signal of monitoring is sent to the photoswitch sensing being connected with the light path distributor
Device；
Judge whether the light path distributor receives and reflect what is obtained by the reflection-type photoswitch sensor
Optical signal is returned to, if so, then all doors of casing are closed, if it is not, then at least one fan of casing
Door is in open mode.
