Beyond limitation, step S3 is executed；
If tMOr tNGreater than pre-set threshold time, return step S1；
S4, when obtaining the information in one-dimension code/two dimensional code, the information in the one-dimension code/two dimensional code include high-tension switch cabinet whether
Security information, the two dimensional code for the visible light alignment prescan that framing emitter is emitted, if the two dimensional code can not be identified,
Then prompt the two dimensional code that can not identify；After two-dimensional barcode information obtains successfully, if high-tension switch cabinet charges, high-tension switch cabinet at this time
It is dangerous, far from high-tension switch cabinet and high-tension switch cabinet input power should be closed；It, can be close to high if high-tension switch cabinet is safe
The cabinet that compresses switch is operated.
7. the control method of non-contact type high voltage switchgear safety detecting system according to claim 6, which is characterized in that
Further include temperature of high-tension switch cabinet monitoring method:
S71, system initialization, order judge that number M=0, the M are positive integer；
S72, controller acquire the voltage value of i-th of platinum resistance thermometer sensor, Rt of t momentCalculate the resistance value of platinum resistance thermometer sensor, Rt at this time
Calculation formula isWherein,The voltage value of i-th of premonitoring measuring point is acquired for t moment controller,For the resistance value of i-th of platinum resistance thermometer sensor, Rt of t moment, R5 is the resistance value of resistance R5, and R4 is the resistance value of resistance R4, and I is constant-current source
The current value of output tables look-up and obtains the corresponding temperature value of platinum resistance thermometer sensor,；
Whether the temperature value obtained in S73, judgment step S72 is greater than or equal to preset temperature threshold, if the temperature value obtained is big
In or equal to preset temperature threshold, then the time is t1 to timer record at this time；If the constant temperature obtained is greater than or equal to default
Temperature threshold and duration are t2, judge whether duration t2 is greater than or equal to preset durations threshold value, if when continuing
Between t2 be greater than or equal to preset durations threshold value, then controller control warning device issue alarm and M=M+1, if continue
Between t2 be less than preset durations threshold value, then warning device is not alarmed and M=M+0；
The size of M value and preset threshold in S74, judgment step S3, if M value is greater than or equal to preset threshold, warning device hair
Alarm and M=0 out, if M value is less than preset threshold, warning device is not alarmed, return step S72.
8. the control method of non-contact type high voltage switchgear safety detecting system according to claim 7, which is characterized in that
It further include the method for calculating temperature sensor height, this method are as follows: Ht=Ht-1+ 2 × π × R × n, wherein HtFor t moment temperature
The location of sensor height, Ht-1For the location of t-1 moment temperature sensor height, R is stepper motor rotary shaft
Radius, n are that rotating cycle is positive, it is specified that rotating clockwise, and rotation is negative counterclockwise.
