Weighted value, the first bed board height, the second elevation weight value and the second bed board height determine that current bed board is high
Degree, and when current bed board height is more than or equal to preset height higher limit, send the too high signal of bed board,
When current bed board height is less than or equal to preset height lower limit, sends bed board and cross low signal；
Wherein, test pattern traffic sign placement below bed board, test pattern mark be shaped as triangle,
Square or circular；
Wherein, landmark identification equipment is by the pixel sum in mark subimage and reference mark image
Pixel sum is compared to determine and exports the first bed board height to include: the picture in mark subimage
Vegetarian refreshments sum is the biggest divided by the numerical value of the pixel sum acquisition of reference mark image, the first bed board height
Numerical value the least, mark subimage in pixel sum divided by reference mark image pixel sum
The numerical value obtained is the least, and the numerical value of the first bed board height is the biggest；
Wherein, module selects selective filtration module in subset to include 3 × 3, and 5 × 5,7 × 7
With 9 × 9；
Wherein, CF card has also prestored default bed board height, the first elevation weight value, the second height
Weighted value, preset height higher limit and preset height lower limit；
Wherein, CF card the most respectively with landmark identification equipment, servomotor and Freescale MC9S12
Chip connects；
Wherein, CF card is additionally operable to prestore each benchmark human body image, each benchmark human body image
The image obtained for the benchmark human body of the different bodily forms is shot in advance；
Wherein, module selects subset to select to carry out the filtering mould of medium filtering based on maximum distribution radius
Block includes: maximum distribution radius is the biggest, and the filtration module carrying out medium filtering of selection is the biggest, maximum
Distribution radius is the least, and the filtration module carrying out medium filtering of selection is the least.
3. Pediatric nursing bed as claimed in claim 2, it is characterised in that:
Module selects subset to use CPLD chip to realize.
4. Pediatric nursing bed as claimed in claim 2, it is characterised in that:
Wireless Telecom Equipment is time division duplex communication interface.
5. Pediatric nursing bed as claimed in claim 2, it is characterised in that:
Wireless Telecom Equipment is frequency duplex communications interface.
6. Pediatric nursing bed as claimed in claim 2, it is characterised in that:
Wireless Telecom Equipment is GPRS communication interface.
