Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is that control module of the present invention connects block diagram.
The specific embodiment
As shown in Figure 1, a kind of erecting equipment remote electric control module based on GPRS cordless communication network, comprises GPRS communication unit 1, remote monitoring platform unit 7.Described GPRS communication unit 1 by: central process unit 2, GPRS module 3, communication output interface 5, switching value control output module, power interface 4 connects to form.Remote monitoring platform unit 7 consists of the server 8 with software support.Said two units forms organic cooperation and realizes long-range lock machine and unlocking function realization.The bi-directional data that central process unit 2 is processed from remote monitoring platform unit 7, GPRS communication unit 1 carries out data transmission with GPRS module 3 by GSM network and server 8 with communicating by letter of remote monitoring platform unit 7.When remote monitoring platform unit 7 has after remote-control operation instruction, first under software support, form data code, then by server 8, for main frame, by GSM network, send to the next GPRS module 3, GPRS module 3 can will send central process unit 2 to after receiving instruction after command reception, central process unit 2 can be decoded to data analysis.According to data type, the command transfer that needs are carried out is given communication output interface 5 and switching value output control module 6, then communicate by letter output interface 5 and switching value output control module 6 will send control command accordingly, go and the plc communication of hoisting crane or the variation of output switch amount, realize the lock machine of hoisting crane or unlocking function.
Implementation step:
1) when, module works:
Module of the present invention is arranged in the on-the-spot electrical control cabinet of weight-lifting equipment.Central process unit 2 can pass through the data (as: according to MODUBS PROFIBUS) of 5 outputs of communication output interface and plc communication, or output heartbeat impulse singla, and this signal is approximately decided to be normal operation with PLC, the sign of non-lock machine state before.PLC is after normally collecting signal or pulse, and whole lifting function is normally used.Simultaneous Switching amount is controlled output module 6 can not drive relay or switch motion yet, and all correlation functions of whole hoisting crane are all that normal condition is used.
2), when needs carry out lock machine requirement to on-the-spot weight-lifting equipment:
In remote monitoring platform unit 7, operate, instruction meeting is sent to GPRS module 3 by gsm wireless network, this module receives after signal, can transfer data to central process unit 2, central process unit 2 receives after data, according to agreement, carries out resolution data, is clearly requirement hoisting crane lock part function, such as: lift control, can correspondingly send to communication output interface 5 and switching value to control output module 6 command format.Communication output interface 5 can be according to the lock machine command format of PLC agreement, lock machine request being sent to PLC, such as being the variation of certain zone bit in communication protocol, or heartbeat impulse singla becomes low level signal, PLC, after collecting this signal, will lock the part or all of operating function of hoisting crane like this.Switching value is controlled output module 6 and can the control that seal in weight-lifting equipment electric loop be opened circuit switching value signal generation saltus step, and this function can not be moved.
3) if need to remove on-the-spot lock machine state:
With reference to 2) mode above, what just transmit is unlock command, GPRS communication unit 1 can recover communication protocol or heartbeat impulse singla.Switching value is controlled output module 6 can revert to normal working by switching value.
4) when, electrician's destruction is safeguarded in on-the-spot lifting:
In prior art, other control module is substantially all by relay or switching value, in the control loop of access weight-lifting equipment, carries out control part electric function.Such as: with normally closed point, seal in hoisting circuit, when hoisting action, because this switching point disconnects, hoist and can not work.Which principle is simple, as the electrician of field maintemance weight-lifting equipment, substantially can understand.General personnel can be directly by on-the-spot that control module power-off, and module is not worked just not can control hoisting crane.Or can find master cock amount position, directly use wire short circuit, even if module is at the control loop that also cannot break of working.GPRS communication unit 1 of the present invention, it can, along with demand, communicate the output of numeral or heartbeat impulse singla, even if hoisting crane safeguards that it is that this module is controlled that electrician finds, also has no idea like this by communication output interface 5.Because can not simulate heartbeat impulse singla or signal of communication by methods such as short circuit wire jumpers, and being pulled out to electricity, this module do not allow its work, also can make PLC not collect signal, and allow hoisting crane in lock machine disabled state.Unless they can change whole PLC, and change PLC, not only need to buy PLC hardware support, also need professional software programming and designer, obvious is like this unpractical.So which can solve on-the-spot user's control and removes.
