Technical solutions of the utility model are：
A kind of domestic waste incineration equipment bi-directional drive hydraulic system connection structure, according to domestic waste incineration equipment
Control requires to establish model control as follows, by the way that communication cable is arranged between automatic combustion switch board and DCS system and connects firmly
Line come realize DCS to burn furnace apparatus fluid pressure drive device bi-directional drive；Domestic waste incineration equipment passes through DCS's
Logic judgment sending device run signal；
The fluid pressure drive device control signal for burning furnace apparatus is sent out by DCS system, by communication cable and special
Communication module is transferred in automatic combustion switch board, then controls the operation of fluid pressure drive device local operation case equipment；It is described
The equipment controling signal that DCS system is sent out connects domestic waste incineration device-specific active station by hardwire and directly controls life
Waste incineration furnace apparatus living.
Further, the fluid pressure drive device control signal for burning furnace apparatus is sent out by DCS, by communication cable and special
Communication module is transferred in automatic combustion switch board, then the operation of control device；Its feature is to realize very complicated
Control technique, resist general electric fault, such as communication interference, CPU interrupt etc..
Further, the equipment controling signal that DCS is sent out can directly control equipment by hardwire；This design can be pre-
Prevent that serious electric fault occurs in automatic combustion switch board, when powering off or do not work suddenly such as switch board, burns furnace apparatus still
The operation that can so stablize under the monitoring of DCS.
In domestic waste incineration automatic combustion switch board, by the way that Siemens's redundant PLC control with flash card is arranged
Device, using special communication module, on the spot be arranged local operation case and burn furnace apparatus fluid pressure drive device main control
Signal is directly connected to the first-class measures of DCS, realizes that DCS can drive the liquid for burning furnace apparatus by the way that communication or hardwire are two-way
It presses drive system and equipment can be operated on the spot, to ensure the system when there is an emergency, in occurring such as a unit
Disconnected or failure, system will be also stored in the data being written in stand-by unit, operation are automatically switched in flash card, and system is not
Meeting interruption of work, enables field device stable operation, if the even more serious failure of entire cabinet all dead electricity, scene is set
It is standby directly to be controlled by hardwire by DCS, ensure the normal operation of incinerator, ensures production.

Specific implementation mode
The utility model connection structure is related to field of household garbage incineration, in particular for about three-stage stoker fired grate formula
The connection structure that domestic waste incineration DCS passes through automatic combustion switch board bi-directional drive hydraulic system.According to burning furnace apparatus
Control requires, and realizes DCS to burning by the way that communication cable and hardwire are arranged between automatic combustion control system and DCS system
Burn the bi-directional drive of furnace apparatus hydraulic system；Redundant PLC control system and special communication mould are set in automatic combustion switch board
Block improves the stability of system and resists the ability of electric fault；In emergency, the fluid pressure drive device of furnace apparatus is burned
The control for realizing equipment operating condition by hardwire by DCS system, to ensure that incinerator normally produces.
As shown in Figure 1, connection structures of the utility model DCS by automatic combustion control system bi-directional drive hydraulic system
Schematic diagram.DCS system is described in Fig. 2 to be transmitted to automatic combustion switch board control signal by the company of communicating, and then existed
By the fine control for controlling the fluid pressure drive device to realize burning furnace apparatus of detailed signal processing and operating status in cabinet
The use of system, special communication module can connect two different network segments, and two network electrical isolation, a network segment failure
The operation of another network segment is not influenced；The utilization of redundant PLC system can prevent general electric fault, ensure the normal fortune of equipment
Row makes equipment meet the needs of factory's normal operation, when automatic combustion switch board fault-free, selects this control mode that can reach
The fine control requirement of equipment；The local operation box of equipment is devised in Fig. 4, can local control unit, be equipment debugging,
Maintenance, equipment performance test etc. need local operation equipment to provide easily mode of operation.
Brief control logic is edited in Fig. 3 in DCS system, after operation, control signal is by the wiring on DCS cabinets
Terminal is directly by the operation of hardwire control device, in this way when automatic combustion switch board powers off or occur serious electric fault
When, burning furnace apparatus still can be by the operation of DCS remote controls and stabilization, to ensure the economic benefit of incinerator.
The explanation calculated about control logic：
Equipment can be run in a manual mode, i.e., only run one cycle, the signal equally can communicate directly or
It is two-way come control device by way of hardwire after easy logical calculated；
Equipment can be run in automatic mode, i.e. continuous automatic running under C/A patterns；The velocity feedback PV values of equipment are big
When speed SV values, an equipment run signal will be sent, which equally can communicate directly or pass through easy logic
It is two-way come control device by way of hardwire after calculating；
Following specific examples for the utility model：
Example is by taking incinerator dries the control of fire grate as an example, and in a manual mode, DCS provides dry fire grate one to equipment
Cycle start signal, the signal Direct Communication send out dry fire grate advance life to the redundant PLC system of automatic combustion switch board
It enables, dry fire grate advances, and when running to advanced potential, dry fire grate feeds back the signal in place that advances, and then redundant PLC system is sent out again
Backward command, dry fire grate retreat, and when retreating in place, dry fire grate stops, and feedback retreats signal in place, terminate cycle
Operation；If operator's selection will control dry fire grate by hardwire, signal needs in DCS system by easily patrolling
It collects and calculates, as shown in figure 5, then directly sending advance, the backward command of dry fire grate by DCS to complete control；If in C/A
Under pattern, then only need, according to the logical calculated of dry fire grate, periodically to send run signal, which equally can be direct
Communication two-way by way of hardwire after easy logical calculated controls dry fire grate；Dry fire grate can also
Moving forward and backward for dry fire grate is realized by local operation case.
