The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in Figure 1; The present invention includes exterior antenna 1, be embedded in many groups inside antenna 2 and ZigBee module 3 in the load-transfer device; Said exterior antenna 1 is connected with the load-transfer device motor, lays along load-transfer device, and the power end of each ZigBee module 3 connects one or one group of inside antenna 2.The ZigBee module 3 that is embedded in the load-transfer device has film shape structure and good flexible; Can not damage because of folding nature; These ZigBee module 3 storage inside modules are used to write down load-transfer device Position Number, date manufactured, effective informations such as load-transfer device accumulative total normal operation duration, damage time.When load-transfer device motor normal operation; Said exterior antenna 1 is transformed into electromagnetic energy with the electric energy that is transmitted; Send the electromagnetic signal of CF continuously, inside antenna 2 is transformed into electric signal with the electromagnetic signal that said exterior antenna 1 sends, for ZigBee module 3 provides power line voltage; Said ZigBee module 3 storages and the higher level control center in Fig. 36 send the load-transfer device information that comprises the load-transfer device Position Number.
As shown in Figure 2, exterior antenna 1 can also be made up of several miniature antennas, is installed in respectively on the bracing frame, is fixed on the band conveyor frame 5.In order to guarantee that there is not the electromagnetic signal blind area in the conveying scene, the effective range scope of each miniature antenna (the first miniature antenna effective range scope 1.1, the second miniature antenna effective range scope 1.2, the 3rd miniature antenna effective range scope 1.3 ...) in conveyor zones, can not have and be interrupted.
As shown in Figure 3, exterior antenna 1 cable is connected with load-transfer device motor 9, the omnidistance laying.When load-transfer device motor 9 normal operation, exterior antenna 1 can send the electromagnetic signal of CF continuously, and belt of belt conveyor places a huge magnetic field fully; When load-transfer device motor 9 quit work, cable stopped to send electromagnetic signal.Higher level control center 6 links to each other with appliance computer 7, and appliance computer 7 is connected with warning device 8.
Said higher level control center 6 can be single-chip computer control system, can be the PLC control system also, be installed in carry on-the-spot near or be installed in the Control Room, link to each other with appliance computer 7, support wired and wireless two kinds of signalling methodss.Said appliance computer 7, warning device 8 are installed in the Control Room, and appliance computer 7 has good man computer interface, and the monitor message of forms such as image, literal can be provided for the monitoring management personnel, and annunciator has sound and light warning dual mode.
Principle of work of the present invention is: be embedded in inside antenna 2 magnetic field environment that externally antenna 1 provides in the load-transfer device, constantly do the cutting magnetic induction line motion with load-transfer device.When belt body was not torn, inside antenna 2 loops were activated, and produced electromotive force, for ZigBee module 3 provides power line voltage.When belt body was torn, inside antenna 2 loops were broken off, and no longer produce electromotive force, for ZigBee module 3 power line voltage are not provided.
The ZigBee module 3 that is embedded in the load-transfer device has two kinds of mode of operation, has film shape structure and good flexible, can not damage because of folding nature.This module also has certain electric charge energy storage capacity, can store the portion of energy that inside antenna 2 transmits.After inside antenna 2 was torn disconnection, the charge stored amount can be supplied power for ZigBee module 3 temporarily, guaranteed that ZigBee module 3 can in time write down, send belt conveyor and tear information, improves system reliability.Two kinds of mode of operation of this ZigBee module 3 are following:
Mode of operation one is by inside antenna 2 power supplies, the portion of energy of stored antenna transmission simultaneously.ZigBee module records load-transfer device Position Number, date manufactured, upgrade accumulative total load-transfer device normal operation duration, and send to higher level control center 6.
Mode of operation two; When inside antenna 2 damages; By the power supply of ZigBee module 3 storage inside energy, the record 3 damage times of inside antenna, produce alerting signal and shutdown signal; Send load-transfer device Position Number, date manufactured, accumulative total load-transfer device normal operation duration, damage time, alerting signal and shutdown signal effective information are given higher level control center 6.
This system works step is following:
(1) belt conveyer electric motor starting, the exterior antenna 1 that is attached thereto is started working, and constantly outwards sends the electromagnetic signal of CF.
(2) load-transfer device normal operation, with the certain speed motion, the inside antenna 2 that is embedded in the load-transfer device is done cutting magnetic induction line motion generation electro-motive force.
(3) inside antenna 2 is 3 power supplies of ZigBee module continuously, and the ZigBee module 3 that is embedded in the load-transfer device receives electric the activation, gets into mode of operation one, initialization record load-transfer device Position Number, date manufactured, the portion of energy of stored antenna transmission simultaneously.
(4) load-transfer device is torn fault, and inside antenna 2 loops are broken off, and no longer produce electromotive force, and ZigBee module 3 gets into mode of operation two, by the power supply of storage inside energy, the record 2 damage times of inside antenna, produces alerting signal and shutdown signal.
(5) ZigBee module 3 is sent load-transfer device Position Number, date manufactured, and accumulative total load-transfer device normal operation duration, damage time, alerting signal and shutdown signal effective information are given higher level control center 6.
(6) higher level control center 6 shows to appliance computer 7 message feedback that receives in the step (5), and opens warning immediately, and the order belt conveyer is shut down maintenance.
On the basis of the foregoing description; Modules such as this intelligent checking system can also extended temperature detection, weight detecting, the detection of skidding; These three kinds of detecting devices insert in the higher level control center 6, constitute the load-transfer device comprehensive monitor system that a cover is accomplished with load-transfer device longitudinal tear intelligent wireless detection scheme of the present invention.
