Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 2, the utility model comprises hand-held remote controller, PLC, PC and multiple upper water bolt unit, described hand-held remote controller is connected with multiple upper water bolt unit respectively, described PLC is connected with multiple upper water bolt unit respectively, described PC is connected with PLC, described hand-held remote controller sends a control signal to water bolt unit, when a certain upper water bolt unit normally can not receive the corresponding control signal that remote controller sends, on other, water bolt unit receives this control signal, and this control signal is sent to PLC, this control signal sends and so far goes up water bolt unit by PLC.
As shown in Figure 3, described upper water bolt unit comprises controller, radio receiving transmitting module, current detection module, closed tube motor drive module, electromagnetic valve, power-transfer clutch, temperature detecting module, heating module, reduction voltage circuit and always stops button, described controller respectively with radio receiving transmitting module, current detection module, closed tube motor drive module, reduction voltage circuit, power-transfer clutch, temperature detecting module, heating module, always stop button and be connected, reduction voltage circuit is connected with electromagnetic valve.
As shown in Figure 5, closed tube motor runs detection and stall detection has two kinds of mode of operation, is respectively DC MOTOR CONTROL mode and AC Motor Control mode.DC MOTOR CONTROL mode adopts ACS712 chip, and this chip realizes the detection to electric current in hall sensing principle.AC Motor Control mode adopts micro mutual inductor to realize current detecting, and by a precision resistance, samples, and read in micro controller system current signal.When needs detect, control motor rotation, chip starts the size detecting current of electric, if current of electric is less than certain setting value, then judges motor dally or circuit as open circuit, controller returns an alerting signal to PLC.Initial several seconds of machine operation unloading phase of being, this stage electric current can exceed default current value, after several seconds, motor should be in normal work stage, if electric current is still greater than default fixed value, then think that the Upper hose of upper water bolt is stuck, controller controls motor and shuts down, and meanwhile, controller returns an alerting signal to PLC, alerting signal is sent into remote controller by PLC, with the failure problems of reminding workman to investigate motor.
The function of electromagnetic valve controls upper water bolt to carry out upper hydrodynamic(al) work, the operating voltage of its normal adhesive is 24V, experiment shows, if electromagnetic valve is in the operating voltage of 24V always, the life-span of electromagnetic valve can reduce greatly, after the normal adhesive of electromagnetic valve, need the operating voltage of electromagnetic valve to be reduced to 8V, can reach like this and extend electromagnetic valve life-span and energy-conservation effect.The utility model arranges reduction voltage circuit between electromagnetic valve domain controller, and the master chip of reduction voltage circuit adopts LM2576, and as shown in Figure 6, this chip uses the mode of PWM, and cal val is very little, can normally run for a long time in the upper water bolt of bad environments.
During the action of driven by motor closed tube wheel, need power-transfer clutch adhesive, to drive the work of closed tube wheel.After water pipe is recovered and put in place, power-transfer clutch power-off, during water, hauls out water pipe easily with expediently water conservancy project people on carrying out next time.Power-transfer clutch pick-up voltage is 24V, power-transfer clutch can not long-term work at this voltage, in order to extend the life-span of power-transfer clutch, needing the operating voltage of power-transfer clutch to switch to 12V equally, realizing this function by a relay.
Always stop function: each upper water bolt unit all has one always to stop button, always stops button and designs to tackle emergency.Once run into emergency, what upper water conservancy project people pressed water bolt unit on any one always stops button, or remote controller always stops button, and PLC issues a control signal, and all upper water bolt unit all stop upper water, and carry out deflating action.
Principle of work of the present utility model is as follows: the point-to-point mode adopting Digiplex under normal circumstances, by Digiplex and on each wireless telecommunications of water bolt unit realize the control to upper water bolt unit; On each control signal that remote controller sends, water bolt unit all has a corresponding feedback command and is back to remote controller; When water bolt unit on certain is because the factor such as being blocked, when normally can not receive the corresponding control signal that remote controller sends, remote control unit does not receive feedback command; Remote controller still cannot receive feedback command through retransmitting, remote controller will issue the instruction that all upper water bolt unit all can identify, on other, water bolt unit receives this control signal, and this control signal is sent to PLC, this control signal sends and so far goes up water bolt unit by PLC, realizes the control to water bolt unit on this; Also have a kind of manual control mode, when remote controlled manner is inoperative, that presses arbitrary upper water bolt unit always stops button, carries out emergency control.
