Abstract
A frequency hopping wireless remote control system of a girdle transport vehicle belongs to the wireless remote control systems, and comprises a programmable logic controller, a wireless remote control receiver and a frequency hopping wireless remote control emitter, wherein the wireless remote control receiver is connected with the programmable logic controller, and the wireless remote controller and the frequency hopping wireless remote control emitter are correspondingly connected. The receiving end of a remote control device is connected with the programmable logic controller through an I/O connecting wire, a remote controller can send out remote control instructions which are transformed into digital quantity or simulation quantity signals after received by the receiving end, the programmable logic controller can send out instructions for all execution mechanisms of a girdle transport vehicle after receiving signals, thereby realizing the operations of moving forwards, backing, braking, lifting of supports legs/suspension and the rotation of a steering room of the vehicle. The frequency hopping wireless remote control system has the advantages of greatly enhancing the stability, and effectively guaranteeing the safety of the girdle transport vehicle and operation personnel, thereby providing flexible control model for the girdle transport vehicle, and assuring the girdle transport vehicle to correctly operate.
Description
Technical field
The utility model relates to the frequency hopping wireless telechirics of a kind of wireless remote-control system, particularly a kind of beam car.
Background technology
Beam car driver under normal row turner condition is driving in-house operation, but aiming at occasions such as bridge formation machine, narrow road conditions, loading and unloading bridge, in order to ensure driver's personal safety, perhaps for the ease of controlling vehicle more accurately, the driver need leave pilothouse, safely, the position being convenient to observe and operate carries out remote control to vehicle.
According to the standard code of national the Radio Management Commission, in the 220-420Mhz band limits, the spendable frequency quantity of industrial wireless remote control system is 23.Because frequency resource is limited, if many robots of different manufacturers during operation, the phenomenon of co-channel interference then can occur inevitably in same work-yard (500 meters of diameters), cause the telechirics can't normal communication, this is the deadly defect of wireless remote control.Because beam car uses the place fixing, service condition changes greatly, telechiric device in use, the place to use may have other radio controlled machinery simultaneously moving, and strong especially radio signal interference source is perhaps arranged.If frequency is interfered, then communication can't effectively be implemented.To cause beam car can't move or malfunction.
The utility model content
The purpose of this utility model is to provide a kind of: the frequency hopping wireless telechirics that also can implement the beam car of communication, control when frequency is interfered.
The purpose of this utility model is achieved in that this wireless remote-control system comprises programmable logic controller (PLC), wireless remote controlled receiver and frequency hopping wireless remote control transmitter, wireless remote controlled receiver is connected with programmable logic controller (PLC), and wireless remote controlled receiver is connected with the frequency hopping wireless remote control transmitter is corresponding.
Beneficial effect owing to adopted such scheme, the present invention includes the programmable logic controller (PLC) that is used for car load control, with the frequency hopping wireless telechiric device that is connected with this programmable logic controller (PLC).The receiving end of telechiric device directly is connected by the I/O wiring with programmable logic controller (PLC), telepilot sends telecommand, receiving end is converted into digital quantity or analog signals after receiving, and send to programmable logic controller (PLC) by stube cable, programmable logic controller (PLC) sends instruction to each topworks of beam car, can realize the advancing of vehicle, retreats, operations such as the lifting of braking, supporting leg/suspension and pilothouse rotation.The real-time of frequency hopping wireless telechiric device and security are good.When telepilot exceeded command range or remote control system and breaks down, controller can be sounded and light warning, has reached the purpose of this utility model.
Advantage: the frequency hopping wireless telechirics has strengthened the stability of telechirics greatly, has effectively ensured beam car and operating personnel's thereof safety, thereby for the beam car system provides steer mode more flexibly, has guaranteed the true(-)running of beam car.
Description of drawings
Fig. 1 is a frequency hopping wireless telechirics connection diagram;
Among the figure, 1, programmable logic controller (PLC); 2, wireless remote controlled receiver; 3, frequency hopping wireless remote control transmitter.
Embodiment
Embodiment 1: this wireless remote-control system comprises programmable logic controller (PLC), wireless remote controlled receiver and frequency hopping wireless remote control transmitter, wireless remote controlled receiver is connected with programmable logic controller (PLC), and wireless remote controlled receiver is connected with the frequency hopping wireless remote control transmitter is corresponding.
This patent is a kind of frequency hopping wireless telechirics of beam car, and its connected mode is seen figure one.Wireless receiver 2 directly is connected by the I/O cable with programmable logic controller (PLC) 1, and the wireless launcher 3 with frequency hopping function is connected with wireless receiver 2 by radiowave.Wireless launcher 3 sends telecommand, after receiving, wireless receiver 2 is converted into digital quantity or analog signals, and send to programmable logic controller (PLC) 1 by connecting the I/O cable, after 1 pair of instruction that receives of programmable logic controller (PLC) is judged, each topworks to beam car sends corresponding actions signal, thereby realizes the advancing of vehicle, retreats, operations such as the lifting of braking, supporting leg/suspension and pilothouse rotation.The real-time of this frequency hopping wireless telechirics and security are good, use more flexible.
The hardware facility of taking in the utility model is the commercially available prod.
Programmable logic controller (PLC) is the commercially available prod, is BOSCH-REXROTH BODAS RC controller.
Wireless remote controlled receiver and frequency hopping wireless remote control transmitter are wireless remote controller, are HBC FST telechirics.
