Abstract
The invention relates to an intelligent tensioning system. The system at least comprises a control computer and hydraulic pump stations, wherein each hydraulic pump station is provided with a PLC for control, each PLC is connected with a pressure sensor and a displacement sensor, each PLC is connected with a wireless communication module, and the control computer is also connected with a wireless communication module or is a computer with the wireless communication function. The control computer and the PLCs of the hydraulic pump stations are respectively connected with one wireless communication module, a wired mode is replaced with a wireless communication mode, and the construction efficiency is greatly improved. According to the system, an alarm for abnormal conditions such as communication interruption, faults of sensors and overrun happening in the automatic tensioning process can be given accurately in time, operators on site are warned to handle the abnormal conditions in time, and therefore it can be guaranteed that a tensioning device is safe and reliable.
Description
Technical field
The present invention relates to a kind of intelligent tensioning system.
Background technology
Intelligent tensioning system applies is in prestressed stretch-draw, and prestressed stretch-draw is to strain presstressed reinforcing steel by jack, gives in advance bridge or member stress application, makes bridge or member produce camber upwards, to improve the supporting capacity of bridge or member.
Mode is before manual stretch-draw, along with technological progress, development place intelligent tensioning now, carry out stretch-draw by Based Intelligent Control control tensioning equipment, the impact of the factors such as stretch-draw is not subject to artificially, environment, can set easily pause point, loading speed by intelligent program, hold the stretching process key elements such as lotus time.Intelligent tensioning system mainly comprises control appliance (computer, PLC, sensor), tensioning equipment (hydraulic power unit, electromagnetic valve), jack, ground tackle etc.
In existing mode, control computer and adopt Industrial Personal Computer (IPC), the Information Monitoring of transferring control command or accepting sensor by controlling computer.Because job site environment is more complicated, adopt Industrial Personal Computer (IPC) to need field connection to arrive the equipment such as controller of hydraulic power unit.And need to have technician all the time supervisory control computer in order to avoid pressure or displacement is transfinited or communicating interrupt, sensor fault and go wrong in stretching process.
Summary of the invention
The object of this invention is to provide a kind of intelligent tensioning system, need the problem of the on-the-spot cable of deploying to ensure effective monitoring and control of illegal activities in order to solve prior art.
For achieving the above object, the solution of the present invention comprises:
A kind of intelligent tensioning system, at least comprise and control computer and hydraulic power unit, hydraulic power unit is provided with the PLC that controls use, PLC is connected with pressure sensor and displacement transducer, PLC is all connected with wireless communication module, and described control computer is also connected with wireless communication module or is the computer with wireless communication function.
Described control computer is laptop computer.
On described control computer, alarm module is installed.
On the controller (PLC) of control computer of the present invention and hydraulic power unit, wireless communication module is all installed, substitutes wired mode by wireless communication mode, greatly improved efficiency of construction.
The present invention passes through audio alert, to the abnormal conditions that occur in automatic Tensioning process, as communicating interrupt, sensor fault or situation about transfiniting is carried out in time, report to the police accurately, remind site operation personnel to process in time, thereby can ensure tensioning equipment safety, reliable.
Brief description of the drawings
Fig. 1 is functional block diagram of the present invention;
Fig. 2, Fig. 3 are circuit theory diagrams of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the concrete equipment such as jack, ground tackle that intelligent tensioning system comprises is not shown in the diagram, and what in figure, mainly provide is control section circuit theory diagrams.Intelligent tensioning system, at least comprise and control computer and two hydraulic power units, each hydraulic power unit is provided with the PLC that controls use, PLC is connected with pressure sensor and displacement transducer, PLC is all connected with wireless communication module, and described control computer is also connected with wireless communication module or is the computer with wireless communication function.
Fig. 2 mainly comprises that AC power passes through air switch Q and be connected frequency converter with control relay KM1, transducer drive motor M.On alternating current circuit, also comprise pump start, stop button; The control coil of electromagnetic valve A, B, indicator lamp L etc.It is PLC power supply that AC power forms dc source by transformer T, rectification and filter unit.
In Fig. 3, PLC is connected with pressure sensor and displacement transducer, and wireless communication module (i.e. wireless transmit receiver module in figure), and PLC is also connected with inverter communication.
In the present embodiment, control computer and adopted laptop computer.Control on computer alarm module is installed, for reporting to the police and related voice function.As: in the time that computer enters intelligent tensioning control program picture, audio alert program starts, and quotes salutatory.A little less than computer identifies communication quality or while not having signal, send audio alert prompting.If PLC, in the time gathering when pressure signal pressure signal not or exceed (0----60MP), sends voice message.If PLC, in the time gathering when displacement signal displacement signal not or exceed (0----200MM), sends voice message.
More than provide a kind of concrete embodiment, but the present invention is not limited to described embodiment.Basic ideas of the present invention are such scheme, and for those of ordinary skill in the art, according to instruction of the present invention, the parameter of designing various distortion does not need to spend creative work.Variation, amendment, replacement and the modification of without departing from the principles and spirit of the present invention embodiment being carried out still fall within the scope of protection of the present invention.
