Mutually combine.To describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Fig. 1 is the complete layout of the control system of concrete soil mixing station provided in an embodiment of the present invention, and Fig. 2 is this
The structured flowchart of the control system of concrete soil mixing station that inventive embodiments provide；As shown in Figures 1 and 2, this is prefabricated mixed
The control system of solidifying soil mixing station can include：The first controller being arranged in concrete mixing plant and first network exchange
Machine, and it is arranged in precast concrete workshop (it can be appreciated that the precast concrete production line shown in Fig. 1)
Two controllers and second network switch；First controller and second controller respectively with first network switch and the second network
Switch signal connects, and is provided with transceiver interface, to enter line number by first network switch and second network switch
According to exchange.This first controller is used for obtaining the work state information of mixing plant and occurs in precast concrete production equipment
Fault time control stop only feeds intake to stirring host.Second controller is used for obtaining the working condition letter of precast concrete production equipment
Breath, and control distributing trolley to stop discharging when mixing plant breaks down.
By the equipment production status information of mixing plant is conveyed to second controller in time so that second controller is to pre-
The working condition of concrete production equipment processed adjusts in time, and the concrete square amount of such as stirring host unloading is less than PC component demand
Amount, the distributing trolley as one of precast concrete production equipment stops discharging, it is to avoid useless mould；Produced by precast concrete and set
Standby work state information conveys to the first controller of mixing plant in time, such as (belongs to prefabricated in distributing trolley and material conveying trolley
Concrete production equipment) stop in time when breaking down feeding intake toward stirring host, it is to avoid concrete wastes, thus realizing concrete
Mixing plant is jointly controlled with precast concrete production equipment, and then improves mixing plant concrete and precast concrete production effect
Rate.
During concrete operations, for realizing the centralized Control in mixing plant side or precast concrete workshop side, above-mentioned prefabricated
At least also there are one of following multiple optimal ways in the control system of concrete mixing plant：
The control system of concrete soil mixing station also includes：First industrial computer, is arranged on precast concrete workshop
Central control room (precast concrete central control room as shown in Figure 1) in, and with described second network switch signal even
Connect, for controlling second controller to work；

Time) discharging finish after return main frame discharge port；Haul is unloaded after the discharge time reaches T2, and distributing trolley has been in material state,
Second controller can be with automatic or manual two ways after the fault message not being connected to mixing plant, distributing trolley, material conveying trolley
Concrete is uniformly dumped in the mould of PC component by setting path, in the process, if second controller is determining stirring
Suspend distributing trolley discharging in time, to avoid producing underproof PC component when equipment breaks down；
According to the work state information of mixing plant, (6) first controllers determine that stirring host discharging finishes after, calculate fortune
Trolley is from the discharge port of stirring host to the two-way time T1 of predetermined station and the discharging that concrete is offloaded to distributing trolley
Time T2 sum, obtains very first time value；When calculating mixing time T3 for every biscuit for the stirring host with stirring host enabling
Between T4 sum, obtain the second time value；When the second time value (T3+T4) is more than or equal to very first time value (T1+T2), control
Mixing plant discharging puts into concrete in stirring host after finishing at once；When the second time value is less than the very first time and is worth, control
Mixing plant discharging finish after postpone Preset Time after again by concrete put into stirring host in, Preset Time be the very first time value and
The difference of the second time value；Adjust stirring host charging time by the first controller can realize stirring station host's mixing time
Main frame discharge port can be parked in time to rear material conveying trolley, lift work efficiency；
(7) weight of the concrete according to shop-fabricated mould demand for the operator A is placed an order by the first controller in time, the
Corresponding information is transferred to second controller by controller in real time, controls the equipment work of mixing plant, so that mixing plant is circulated
Generation reaches efficiency and maximizes；In mixing plant production process, the disk number of production, square amount information are reached by the first controller and send out
Deliver to second controller (or first industrial computer), for operator A reference.
The present embodiment is pre- by being respectively sent to the work state information of mixing plant and concrete indigenous equipment in real time
The second controller of concrete production workshop processed side and the first controller of concrete mixing plant side, control in order to two
Device is controlled in time to the equipment of corresponding side, realizes the slitless connection that mixing plant is controlled, such energy with concrete indigenous equipment
Effectively reduce concrete and waste and avoid the phenomenon that PC component is scrapped because of the PC component that concrete square amount deficiency causes, effectively improve
Mixing plant concrete and precast concrete production efficiency.
