With the development of the social productive forces, the people's production and living environment has been improving. Global environmental pollution situation more and more severe, frequent wide range of infectious disease, in addition to a number of biochemical pollution caused by sudden events, our air microbial capture techniques have become increasingly demanding. Microbial air sampler, demand, and the deficiencies of the existing sampler developed an intelligent microbial air sampling system. The system is fully functional, stable operation, environmental adaptability, security monitoring, automatic control via GSM network intelligent interaction with the staff, to meet the requirements for the unattended case for a long time continuous work, especially for harsh environments under microbial air sampling. This paper studies the work include: (1) design and sampling system hardware circuit, including: flow control unit, three-dimensional motion of the main robot control unit, the gripper control unit, lettering control unit, power management module, GSM communication module, safety monitoring module, information storage module, Vice mechanical hand refrigerator door control group, the system clock module, touch LCD screen module, light-vehicle refrigerator's power control, to complete the various units and modules of the realization of the program demonstrated, hardware design, circuit board welding; (2) The use of C language embedded software programming to the master controller, the flow control unit, the master manipulator 3D motion control unit, the gripper control unit, lettering control unit, etc., and finished debugging; (3) the use of the C on the indoor remote control computer application software programming unit, and complete sampling systems and remote control unit between the FBI; (4) of the sampling system for stand-alone use functional testing and remote control function test, and analysis of the field of application of the system and application prospects. The main innovations of this paper are: (1) The main robot crawl dish using the three-finger gripper fingers stretching through hybrid linear stepper motor control and force sensor is installed on each finger for the size of the pressure plate's efforts to obtain palm and finger crawl dish the size of the intensity to achieve system flexibility; (2) the location of the main robot control, control of the three-dimensional coordinates for the system, especially through the three-dimensional coordinates to achieve sufficient precision positioning requirements ; (3) to the safety monitoring module specially designed for this system, including a vibration signal monitoring circuit the device attitude monitoring circuit and the GPS positioning system, the safety of three insurance, real-time monitoring of vibration of the equipment, the inclination of the posture and other conditions, and generating an alarm if necessary, and accurately determine the current position of the device by the GPS, to prevent the occurrence of unexpected situations; (4) in order to mark each sample plates sampling time, sampling results and other data, especially developed lettering unit, through the precise control of three-dimensional movement of the probe, lettering, the device is compact design, wide temperature ranges, can be completely resolved, such as ink-jet printing bulky, complex structure, severely limited temperature problem; (5) For the convenience of the technical staff to maintain the equipment at any time, the system uses a 5.7-inch touch screen convenient human-computer interaction.
