Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further set forth the specific embodiment of the utility model:
As shown in Figure 1; Bridge crane wireless alarming system; It comprises transmitting set 1, pulse code modulator 2, wireless receiver 3, pulse encoding demoder 4, light warning switch 5, alarm lamp 6; Said transmitting set 1 is installed on the bridge crane equipment; And said transmitting set 1 transmits wireless receiver 3 through said pulse code modulator 2 with signal, and this wireless receiver 3 connects said light warning switch 5 through a pulse encoding demoder 4, and said light warning switch 5 connects control one alarm lamp 6.
Alarm lamp 6 carries out coding and decoding by the coding chip PT2262 of independent Microchip-CPU and control thereof.
Native system is mainly used in harbour bulk handling security of system and produces.Native system can adapt to a handling labor operating area, and by the bulk handling occasion of the machinery that clears the ship under two bridge crane equipment and the Duo Tai cabin, two lines can be worked simultaneously, does not disturb mutually.Work when the application of native system will significantly reduce man-machine mixture operation in the handling process is dangerous, improves the job security of the mechanical equipment chaufeur that clears the ship under the cabin, the generation of minimizing accident.
The utility model is made up of two transmitting sets 1 and many dual coding wireless receivers 3.Emitter 1 is installed in respectively on two bridge crane equipment, and working power is 220 volts of alternating current; Wireless receiver is installed in the operator's compartment of the mechanical equipment that clears the ship under the cabin, and working power is 24 volts of direct current (DC).
When motion parts arrived desired location like grab bucket, fishhook etc. by the PLC automatic guidance, transmitting set 1 sent through the time-division of encoding process control warning signal; After the interior wireless receiver 3 of mechanical equipment operator's compartment that clears the ship under the cabin receives the warning signal of corresponding specific radio emitter 1; Pass the signal to light warning switch 5 through pulse encoding demoder 4 and open alarm lamps 6 warning signal that flashes immediately, remind chaufeur to note.3-5 is after second; Transmitting set 1 sends through the time-division of encoding process control alarm cancel message once more; After the interior wireless receiver 3 of mechanical equipment operator's compartment that clears the ship under the cabin received the alarm cancel message of specific radio emitter 1, the warning signal of alarm lamp 6 was closed in control.
The system of the utility model adopts the high-performance microprocessor of U.S. MICROCHIP production as the master control device, and it has the WATCH-DOG timer and the internal oscillator of high reliability, and has adopted the special-purpose Control Software of industrial grade PLC to design.Automatically i.e. operation after the device power: on receiving automatic control signal during saltus step, the work of controlled in wireless remote alarm device.Adopt industrial wireless remote control module by the frequency stabilization of deep surface device and own coding/decoding module, the transceiver working stability is reliable, can not cause interference to other wireless telecommunications system.Move reliably for guaranteeing security of system in when design, to the tight logic control of the emission employing of wireless signal and time schedule control as assurance; Automatically the monitoring of environmental interfering signal is avoided the influence of high reject signal to emission coefficient intelligently, solves the problem that interferes with each other between emitter with the time-division mode.Receiver has self-locking function, and antijamming capability is strong.The main service side used high disturbance rejection of the utility model, and can allow to use many emitters to work simultaneously, do not disturb mutually; Receive, resolve the bridge crane control command, produce W-net control command sequence; To W-net instruction carrying out disturbance rejection data and sequential algorithm coding; Send the W-net control command; Receive the emergency instruction that client is sent, the work of control critical alarm lamp; The work state information that the automatic reception client is sent.The customer service end has according to strong disturbance rejection, strong antidetonation, anti-fight, anti-tide design, and adopts the single-chip microcomputer control technology design, includes bridge crane compiling of instruction sign indicating number module; Start working through the frequency range change-over switch in the start back; Receive the wireless sequential coding instruction that W-net sends, the work of control warning lamp.
