The specific embodiment
Followingly provide the specific embodiment of the utility model, be used for the utility model is further described with reference to accompanying drawing.
Embodiment 1
The mine self-lift control system of present embodiment; Comprise PLC Programmable Logic Controller 1; PLC Programmable Logic Controller 1 is connected with PC 3 communications through PROFIBUS-DP fieldbus 2 and MPI program design platform 4; MODBUS bus 5 one ends are connected with PC 3 communications through MPI program design platform 4, the other end be located at the down-hole, be used to gather the personnel in the pit station marker light box 6 communications of cage demand information are connected, also be connected with on the MODBUS bus 5 and Narrowband Integrated Services Digital Network 15 communication bonded assembly demoders 14; PC 3 also communication is connected with frequency converter 7, and the mouth of frequency converter 7 is connected with the gig communication that is used to promote downhole materials; PLC Programmable Logic Controller 1 adopts S7-300 PLC; Gig comprises the alternating current dynamo 8, the retarder 9 that are connected successively with frequency converter, be used to promote the reel 10 of material and through hardwire mode and PC 3 communication bonded assembly disc-brakes 11, brake pump 12, lubricating pump 13; The quantity of station marker light box 6 is 2-16, is located at each middle section of down-hole.
The safe hydraulic pressure system, it comprises proportional pressure control valve controller, cross valve controller and the control corresponding algorithm thereof that aims at the Hydraulic Station configuration, they are connected on the data acquisition module of PLC Programmable Logic Controller 1 through hardwire.
The utility model is based on the self-lift control system of S7-300 PLC; Adopting S7-300 PLC is master control unit, with underground signal case and main control PLC networking, can reach the signal centralized control through MODBUS; Centralized management; The function of uniform dispatching, total system are divided into central primary control, signal master control, station marker light box and gig, introduce respectively below;
1, gig: gig is the object that frequency conversion is transformed; Except that basic machine; It also comprises performers such as alternating current dynamo, drg, Hydraulic Station and auxiliary brake pump thereof, lubricating pump, electromagnetic valve, and coder, near the sensor of reaction gig work states such as switch.
2, station marker light box: station marker light box is positioned at each middle section, down-hole, is used for intercommunication between realization and signal master control.Both be responsible for transmitting the gig current state downwards, be responsible for upwards transmitting the state and the operating order in stage casing of living in again.
3, signal master control: the signal master control generally is positioned at the central primary control place, and its effect is and the station marker light box communication, collects the order that each station marker light box sends, and keeps watch on each station marker light box state; And some state transfer that central primary control is provided are given each station marker light box.In addition, except that two-way interim data, the signal master control also is responsible for providing some sound and light alarm signals and other subsidiary signal.
4, central primary control: central primary control is the brain of total system; Comprise that PLC Programmable Logic Controller 1 connects and composes with PC 3 communications through PROFIBUS-DP fieldbus 2 and MPI program design platform 4; Be responsible for the request of station marker light box is responded; Operation to the driver is handled, and the state of system is kept watch on, and the safety of system is protected.
5, other accessory equipment: these are transferred and mainly comprise frequency converter, relay control device etc. fully, in order to the control of auxiliary centre master control realization system, perhaps when central master control was lost efficacy, substitute it and accomplish basic function.Because central primary control only is the completion logic processor active task and data orders is carried out task for processing, but it can not provide equipment needed signal, need change usually, so this part also is necessary.
The radical function of the utility model comprises motion control, data acquisition and supervision, man-machine interaction, safety and protection.Provide concrete function below.
1, based on general operation and the operation control system of S7-300PLC
Owing to will realize that automatic operating need carry out a large amount of floating point operations, so speed becomes one of target that system design pursues, and S7-300 compares fast 4 times of S7-200, therefore selects for use it as the central primary control core cell.With gig each item index parameterization, when programming, adopt modular construction, make it have certain commonality, to needing to revise partial parameters and part of module in the different elevator system; Each item requirement that consideration possibly run into comprehensively when system design makes it meet the requirement of most of elevator system.
2, complete/S. A. operation control system
Fully automatic operation pattern and elevator are similar, and during normal operation, the driver does not participate.Central primary control is wanted jar according to the down-hole and the gig state is accomplished driving, parking, slow motion automatically, changed operation such as layer.To the safety problem of being worried, introduced the S. A. operational mode, be that with the difference of fully automatic operation pattern each operation all needs the driver to give an acknowledgment signal, if this signal not, gig does not move.In this pattern, the driver can independently drive through touch-screen in addition, but motion process is to accomplish automatically.Entirely/the S. A. operational mode alleviates driver's working strength greatly, enhances productivity.
3, based on the high precision position control system of improving velocity curve
Under automatic mode, what provided by station marker light box or driver all is action command, and concrete motion process is accomplished by gig automatically.Here mainly contain driving and change two kinds of motion of layer.For driving, its range ability is longer, and speed is higher; Be while guaranteed efficiency and running precision; Designed based on improved S shape velocity setting kinetic control system, whole process has been decomposed into 10 stages, guaranteed that each stage speed, acceleration/accel all have flatness.For changing layer, because range ability is shorter, running velocity is low, for simplicity, has designed three sections motion control patterns, is respectively uniform acceleration, at the uniform velocity section and even braking section.Under these improved movement control mode effects, not only can improve accuracy of positioning, also because the flatness of motion process makes the life-span of frequency converter prolong, operational process is also more steady.
4, based on the distributed signal case system of MODBUS
The MODBUS bus is introduced in the station marker light box system, because that station marker light box distributes is wide, general mine all has hundred meters even km dark, if therefore adopt hardwire, can increase no small cost, in addition construction has also been increased difficulty.Utilize the MODBUS bussing technique,, can practice thrift cost, increase system flexibility on two lines, transmitting behind the data compression coding.
The utility model has following function:
1, central primary control is to gig and hydraulic safe system implementation comprehensive monitoring, in case the hard stop that breaks down guarantees security of system.
2, the central primary control load is handled the collection of external command, and carries out.
3, central primary control and underground signal system keep information mutual communication at any time, and the personnel in the pit can understand the gig running state through the underground signal case, and aboveground personnel also can be through its understanding underground signal demand of signal aspect and indication.
4, unite use through S type velocity curve and the down well placement testing agency of calculating, reach the function of accurate parking.
