Described remote diagnosis terminal 10 is fault diagnosis functions of finishing crane control system by the SMS that uses the mobile phone cat module 20 in the mobile phone cat.
The composition of this collective and distributive type crane control system mainly contains, central control unit, main hook controller, auxiliary hook controller, No. 1 large vehicle controller, No. 2 large vehicle controllers, agv controller, big or small hook weighing scale, the servo-actuated video monitor of main hook, the servo-actuated video monitor of auxiliary hook, handheld operation device, the compositions such as remote diagnosis terminal.Remote diagnosis terminal can link to each other with central control unit by ethernet port, also can connect the CAN bus and obtain the part system information in the situation of terminal failure.The servo-actuated video monitor of master/auxiliary hook links to each other with central control unit with servo-actuated control line by video interface, and other equipment are interconnected by the CAN bus.
No. 1 large vehicle controller, No. 2 large vehicle controllers, agv controller, the hardware such as main hook controller and auxiliary hook controller form identical, CAN bus interface circuit, microcontroller 24, the compositions such as 6 road signal output detections loops.The feature of this controller hardware design is: the signal output channel adopts has the soft switch energy conversion principle of isolation features, so that all failure modes of related device all finally cause the blackout of mouth in the path.The detection input circuit gathers the relevant device running state from the end of output channel by signal conditioning circuit.Microcontroller 24 is done preliminary fault by the information of analyzing and testing signal and CAN bus and is judged that the discovery fault just stops the operation of controlled device immediately.
The composition structure of size hook weighing scale as shown in Figure 4, weighing scale is measured the weight of hook and little hook weight simultaneously, and send to master controller by the CAN bus in real time, master controller is presented at the weight weight that receives on the LCD screen, in case find that weight is overweight, can send sound and light alarm information, hook or the little hook to correspondence sends information out of service simultaneously.The overweight meeting of weighing scale software discovery weight is turned off overweight hook control power supply by the output channel of correspondence in addition.
The servo-actuated video tracking platform of main hook, the servo-actuated video tracking platform of auxiliary hook link to each other with central control unit with servo-actuated control port by different video input mouths respectively, and video monitor is installed on the servo-actuated platform of two dimension.The software of central control unit has major-minor hook video identification function, seeks corresponding main hook or auxiliary hook by videoscanning on a large scale, find main hook or secondary enough after, automatic focusing obtains pure and fresh weight image, handled easily person observes and judges.This part function is characterised in that the image segmentation identification of main hook and auxiliary hook is used for the monitoring function of hoisting crane.
The structure of remote diagnosis terminal forms as shown in Figure 6, main arm processor, and the mobile phone cat, Ethernet interface and CAN interface circuit form.After arm processor received the information note of our corporate server transmission by the mobile phone cat, arm processor read the system status information of central control unit by Ethernet interface and sends to the server of my company by the mobile phone cat.Company technique person can judge the fault of system by the status information of analysis system, and gives the exclusion program that is out of order.Remote diagnosis terminal is characterised in that the SMS that uses the mobile phone cat finished the fault diagnosis functions of crane control system.
In order to improve system's reliability of operation, in Software for Design, adopted the mode of operation of uninterrupted message sense.The major-minor hook is identical with the pattern that dolly adopts, that is: after the input of central control unit identifying operation handle, beginning is to the controlled object (main hook of correspondence, auxiliary hook or dolly) the transmission packets of information, the soft timer simultaneously corresponding with controlled object resets, controlled object begins timing after receiving packets of information, send the feedback information bag to central control unit simultaneously, after central control unit receives the feedback information bag, and then reset timer and send packets of information to controlled object at this, controlled object repeats identical response.The like this transmission that goes round and begins again of the packets of information on the CAN bus has formed a message sense.In the process of this message sense operation, in a single day system breaks down, if there is terminal (master controller or controlled object) not receive packets of information in 10 milliseconds, this terminal sends order out of service immediately, the operation of termination device.The cart control process is from above a little some is different.The formation of message sense is that central control unit send information to large vehicle controller No. 1, No. 1 large vehicle controller to No. 2 large vehicle controller, and No. 2 large vehicle controllers are to central control unit, and operation successively goes round and begins again.Any reason causes one of them not receive packets of information, finally all can cause two large vehicle controllers almost simultaneously out of service.Behind the handle manipulator connecting system, handle manipulator and central control equipment form new message sense, and the interruption of this message sense can cause all equipment out of service.
In Design of System Software, introduced fault detection module.At system's run duration, the flow of information situation on the CAN bus is monitored in each operation of this module records operator, and the concrete time of operation simultaneously, can record all packets of information strange phenomenies, and the time of phenomenon generation.The final information storage that forms by the analysis to information storage, draws the status information of system, and in read-out display reminding information, the potential fault that exists in the display system, and solution.
Because what native system adopted is the collective and distributive type master mode, controller and controlled object mounting arrangements are together, used connecting cable is only used a power cable and a control cables, reduced to amplitude peak the use amount of system cable, normalisation and modularized design scheme have also been adopted in the controller design.Material and the human cost of whole system installation and maintenance have finally been reduced.
The soft switch energy transmission mode with isolation features that the controller signals output channel adopts, after organically combining with the message sense mode of operation of software, system has just had powerful own stability, any system failure all can cause emergency brake, prevent the generation of accident, improved the reliability of system.
The fault detecting software module has been collected personnel operation and the system exception information of system's run duration, the final data bank that forms, greatly improved the level of IT application of control system, especially with the combination of remote diagnosis terminal, realize the after-sales service mechanism that remote diagnosis and fault are got rid of, ensured user's interests the largelyst.
The introducing of the servo-actuated following function of video has improved operator's visual effect, has improved operating efficiency, has reduced misoperation, has also improved Security of the system simultaneously.
Above embodiment only is used for illustrating preferred implementation of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken that described field those of ordinary skill possesses; any modification of doing within spirit of the present utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technical scheme scope that the utility model asks for protection.
