Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment：
The utility model is described further with embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, bridge crane remote intelligent monitoring system, including sensor assembly, the sensor assembly are adopted
The job information of collection crane is sent to on-site terminal, and the on-site terminal communicates with host computer, the host computer and long-range prison
Survey terminal communication；The on-site terminal is also connected with alarm module；
The sensor assembly includes limiter, lifting altitude upper limit before and after absolute value type encoder, big trolley travelling
Device, lifting altitude lower retainer and monitoring weight sensor.The on-site terminal uses PLC.
Using the global design scheme of " PLC+ host computers ", local Wi-Fi wireless communications, strange land GPRS phases interconnect the system
The mode connect, wherein PLC are the control core of whole system, can cross the general monitoring function completed required by crane；It is upper
Extension and reinforcement of the machine as systemic-function, have the function of data record, production management, safeguard protection, alarm etc..
Lifting altitude upper limit device and lifting altitude lower retainer：Number is specified when the number of turns of reel winding steel wire reaches the upper limit
During value, cam mechanism touches upper limit switch, when the suspension hook be located at limes superiors position suspension hook stopping run up in order to avoid rushing to summit；Work as reel
The number of turns of winding steel wire reaches lower limit when specifying numerical value, and cam machine lower limit is absolved from suspension hook stops when the suspension hook is located at limit inferior position
Only operation downwards exceeds safety loop to prevent the steel wire rope on reel from landing, and suspension hook " warp " accident occurs.
Limiter before and after big trolley travelling：It is spacing that a pair of of operation should be all installed in large and small two terminal of car, to protect certain proper fortune
Row mechanism to zero point, up to final position or when running into adjacent driving, crane can disconnect general supply automatically, to prevent the mechanism from going out
Existing offside accident.
Travelling mechanism tachogenerator：Big trolley can be calculated by the rotating speed and rotation direction of measurement motor axis, risen
Speed, displacement and the direction of mechanism are risen, therefore travelling mechanism operational monitoring can be with the absolute value type encoder of measurement angular displacement come real
