Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
See Fig. 1, this figure is the process flow diagram of a kind of engineering machinery halt control method first embodiment provided by the invention.
In the present embodiment, comprising:
S101: the stop instruction of monitoring plant equipment.
S102: detect electrical equipment temperature.
S103: judge that described electrical equipment temperature meets halt condition.
S104: if described electrical equipment temperature meets halt condition, control described plant equipment hard stop.
S105: otherwise, control described plant equipment Delayed shutdown according to described electrical equipment temperature.
In the present embodiment, the stop instruction of first real-time watch device.This instruction can send automatically for HCU, also can send for operating personnel manually operate.
After monitoring equipment downtime instruction, current electrical equipment temperature can be detected, and judge whether current electrical equipment temperature meets preset halt condition.
Wherein, halt condition can be the boundary value arranged electrical equipment temperature, if namely current electrical equipment temperature meets the temperature requirement specified in halt condition, and can opertaing device hard stop.
And if current electrical equipment temperature does not meet the requirement of relevant temperature in preset halt condition, then need employing Delayed shutdown strategy.Namely currently can not, at once by equipment downtime, equipment work be also needed to drive the work of the radiating subassembly such as radiator fan and water pump, to reduce the temperature of inner electrical equipment.After reaching halt condition, then control mechanical equipment downtime.
In the present embodiment, the first stop instruction of monitoring equipment, detects electrical equipment temperature afterwards, if electrical equipment temperature meets halt condition, then controls plant equipment hard stop, otherwise, according to electrical equipment temperature controller tool equipment Delayed shutdown.By using above method, can judge that reaching certain condition in electrical equipment temperature just shuts down, and avoids the problem that the high-temperature residual heat of electrical equipment can not dispel the heat in time, reducing the generation of fault, improve the serviceable life of element.
The present embodiment is a kind of engineering machinery halt control method second embodiment provided by the invention.
In the present embodiment, mainly specifically disclose halt condition, and the rate-determining steps taked when determining Delayed shutdown, specifically comprise:
Due to the kind of plant equipment and the difference of model, the halt condition for plant equipment can arrange no temperature Rule of judgment.
In the present embodiment, described halt condition can be: described electrical equipment temperature is less than or equal to 50 DEG C.If the temperature of namely current electrical equipment is less than or equal to 50 DEG C, plant equipment hard stop can be controlled, no longer need plant equipment to provide power technology radiating subassembly to dispel the heat.
And if electrical equipment temperature is greater than 50 DEG C, then thinking current should carry out Delayed shutdown, can take different control measure according to the concrete condition of current electrical equipment temperature.Specific as follows:
If electrical equipment temperature is in 50 DEG C ~ 55 DEG C, radiator fan is set to low speed state, water pump is set to low speed state; If or electrical equipment temperature is in 56 DEG C ~ 60 DEG C, radiator fan is set to high-speed state, water pump is set to low speed state; If or electrical equipment temperature is higher than 60 DEG C, and radiator fan is set to high-speed state, and water pump is set to high-speed state.
After radiator fan and water pump also work according to above-mentioned strategy setting, when the temperature of electrical equipment reaches halt condition; Or after radiator fan and water pump normally run certain hour, mechanical equipment downtime can be controlled.
In addition; do not meeting under halt condition, can also be pointed out to operating personnel by alarm mode, plant equipment should power on by teaching process personnel; to be done to carrying out lower electricity operation after the heat radiation of inner member again, thus avoid operating personnel to the random closedown of plant equipment.
Because engineering equipment operationally may need emergency stop because of the situation in the external world.In this case, as long as detect that stop instruction is emergency stop instruction, then do not need to judge one by one according to Delayed shutdown strategy again, but control described plant equipment hard stop.
In the present embodiment; to the Provisioning Policy of plant equipment and pump working state when essentially disclosing condition and the Delayed shutdown of shutdown; thus avoid the problem that the high-temperature residual heat of electrical equipment can not dispel the heat in time, reduce the generation of fault, improve the serviceable life of element.
Based on a kind of above-mentioned engineering machinery halt control method method, present invention also offers a kind of engineering machinery stop control apparatus, describe its ingredient in detail below in conjunction with specific embodiment.
