Embodiment:
Below in conjunction with drawings and Examples the present invention is further described.
Now explain its characteristics and advantage by specific embodiments of the invention and in conjunction with its accompanying drawing:
According to one embodiment of present invention, the safety supervisory system comprises a plurality of sensors 1 that are positioned at a plurality of hoist points, and each hoist point is provided with a sensor 1, and this sensor 1 is used to detect the real-time stress value of this hoist point, produces the stress value simulating signal; The a plurality of digital variator 2 that is connected with a plurality of sensors 1, each digital variator 2 is connected with a sensor, the stress value analog signal conversion that is used in real time this sensor being produced becomes to meet the digital signal of RS485, and this digital signal is sent on the RS485 bus 3; RS232 RS485 converter 4, the digital signal that is used for sending on the RS485 bus 3 converts the digital signal that meets RS232 to; Computing machine 5 is used to accept the digital signal that this meets RS232, and the stress value of each hoist point is monitored.In this embodiment, sensor 1 uses MS-2 type LOAD CELLS; It is the digital variator of SDT-II type that numeral variator 2 adopts the model that goes up the production of photoelectron Science and Technology Ltd. of Hisense.
Consult Fig. 2, sensor 1 is installed in the junction of screw mandrel 6 and steel platform 7, and wherein the other end of screw mandrel 6 is connected with the lifting means (not shown).
After the sensor 1 that is positioned at each hoist point records the stressed numerical value of each hoist point, the simulating signal that sensor transmits is converted into digital signal in real time by digital transmitter, again through RS232 the RS485 converter digital signal is sent to PC.Digital transmitter is that the signal processing circuit of core constitutes with the single-chip microcomputer by one mainly, and its main effect is the calling of host computer to be made reply, simultaneously the pulling force signal that sensor is returned through amplification, A/D conversion and single-chip microcomputer handle.PC adopts the RS232 serial port of standard to communicate, but the RS232 serial-port communication is apart from weak point, and the equipment that surpasses more than two can not be arranged in a connection, therefore can not satisfy the requirement of distributed data acquisition system.And the RS485 serial port has multiple spot, two-way communications capabilities, promptly allow a plurality of transmitters to be connected on same the bus, and communication distance is far away, can reach more than the km, is applicable to system requirements.Therefore, this digital transmitter adopts the RS485 serial port, transmit by the RS485 bus, then by a RS232 the RS485 converter be connected with computing machine, to reach the purpose of communication Protocol Conversion.
After computing machine is accepted these a plurality of value of thrust digital signals, produce the real-time stress numerical value of each hoist point, and on display screen, show the histogram of the real-time stress numerical value of each hoist point.The monitor staff can see the histogram of each hoist point simultaneously in a display screen, and according to histogrammic concrete condition the stressing conditions of integral self-lift steel platform system is carried out manual intervention, carry out manual intervention as utilizing the time length of opening or closing the lifting means of each hoist point.Compared with the value of thrust data that on display screen, show each hoist point simultaneously, show that histogram is more directly perceived, can be very clear to the stressing conditions of each hoist point simultaneously.
The higher limit and the lower limit that also can show the stressed numerical value of each hoist point on display screen simultaneously, higher limit and lower limit adopt corresponding numerical value according to the lifting means that adopts.Whether the actual loading value that makes the monitor staff can observe each hoist point more intuitively exceeds limits.
Can also be on display screen the histogram summit of each hoist point be coupled together, form the actual loading curve, at display screen each hoist point higher limit and lower limit are coupled together respectively simultaneously, form upper limit line and lower limit line.So only need to observe the variation of curve, just can understand the variation of each hoist point actual loading value.
When the stressed numerical value of any one hoist point exceeds the higher limit of the stressed numerical value of this hoist point and lower limit, close the lifting means of this hoist point.Can directly control lifting means by computing machine, more rapidly safety.
According to one embodiment of present invention, on display screen, also shown workbench three-dimensional simulation dynamic demonstration graph.When the stressed numerical value of any one hoist point exceeds the higher limit of the stressed numerical value of this hoist point and lower limit, stop this workbench three-dimensional simulation dynamic demonstration graph, close the lifting means of this hoist point simultaneously.Just often, the workbench in the workbench three-dimensional simulation dynamic demonstration graph moves, and when going wrong, the workbench in the workbench three-dimensional simulation dynamic demonstration graph has stopped.Wherein the motion of workbench can be arbitrarily, as long as just often and when going wrong, the state of workbench is just passable to stopping from motion change.
When the real-time stress numerical value of one of them hoist point exceeds the higher limit of the stressed numerical value of this hoist point and lower limit, can also be in display screen display monitoring space of points distribution planimetric map, and carry out alarm indication at the hoist point place that exceeds limit value.The monitor staff just can find the hoist point that goes wrong easily like this.
It below is the process description that computing machine is monitored the stress value of each hoist point among the present invention.As shown in Figure 6, in data base access module 601, the initialization data storehouse is read and write database the setting of correlation parameter and is upgraded by the user.In data communication module 602, computing machine 5 communicates according to deciding agreement with digital transmitter 2, obtains the real time data that digital transmitter 2 returns.In data processing module 603, computing machine 5 is converted to actual value of thrust with the gained data, judges the seat in the plane state and carries out respective handling and control according to setup parameter.In data disaply moudle 604, the real-time value of thrust of each seat in the plane and the state form with histogram and spatial distribution map is shown.In data memory module 605, seat in the plane information is stored in the middle of the text document in chronological order, for future referencely see and print.
