Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Fig. 1 is intelligent patrol detection firefighting warning linkage control system schematic diagram of the present invention, having outside basic fire protection warning and linkage function, also comprises: the control appliance that can carry out to the fire pump of the fire water supply equipment of chemical industry plant area, foam pump automatic detecting.This control appliance by starting the high-tension switch cabinet 1 of fire pump and foam pump, frequency converter 3, transformer 4, automatic detecting controller 5, vacuum contactor 6 and the optical fiber control circuit 7 of patrolling and examining in switch board 2 and cabinet forms.This equipment has 2 kinds of duties: non-fire-fighting work state and fire-fighting work state.In the time of non-fire fighting state, the Clock enable of patrolling and examining by automatic detecting controller 5 is patrolled and examined program, it makes frequency converter 3 export the alternating current of a lower frequency, this alternating current is fed on the motor of high-pressure service fire pump by one group of vacuum contactor 6 after boosting by transformer 4 again, this motor rotates fire pump with a low rotating speed, make so, one by one every fire pump and foam pump move like this 5-10 minute.So periodic automatic detecting, can thoroughly solve the dead problem of rust that fire pump and foam pump need not cause for a long time.In the time carrying out above-mentioned automatic detecting, if while there is the faults such as power supply phase shortage, under-voltage, motor overload, short circuit, can send immediately alarm signal.Optical fiber control circuit 7 is a kind of safety circuit modes that adopt in the time controlling high-tension circuit, can complete control logic, there is no again the apprehension of danger of high voltage level.In the time of fire fighting state, the startup command that can be sent by central fire control point or the preset threshold values being provided by Pressure gauge make fire pump, foam pump start immediately and move with rated speed, provide fire water supply and foam with specified lift and flow, complete the fire extinguishing of tank farm.After fire-fighting event finishes, manual-lock fire pump and foam pump.Fire pump or foam pump are set as the standby or the using and the reserved of 2 use one conventionally, if fire pump or foam pump are moved failure of pump in the time that fire-fighting moves, stand-by pump can drop into automatically.
The control appliance that can carry out automatic detecting to each electrically operated valve equipment of Oil Tank Area is made up of PLC 8 and motor-driven valve distribution box 9, as shown in Figure 3.By in programmable logic controller (PLC) (PLC) 8 the program of patrolling and examining Clock enable and patrol and examine electrically operated valve, this program makes the contactor action separately of the interior each valve of motor-driven valve distribution box 9, make the open one by one-closed set of electrically operated valve in tank farm, after each electrically operated valve action, position switch on electrically operated valve can synchronously provide valve open or closed state, this state feeds back to PLC 8 one by one, then the qin formula operating desk 14 that is sent to central fire control point is shown.
Each equipment is presented at equipment state in the electronic display 13 and Qin Shi operating desk 14 of central fire control point in the mode of duplex signaling interlock with central fire control point with, switch 10 and ring-type Ethernet 11 in real time by PLC 8, corresponding each interlock object that passes to of instruction also fire-fighting center being sent simultaneously.
The Pressure gauge group 12 that can indicate in real time fireproof water tube net state is made up of the Pressure gauge being arranged on the pump discharge, fire fighting supply main pipe, arm of each fire pump and foam pump.The force value of each Pressure gauge instruction is given the interface of the mould/number conversion in PLC 8 with analog quantity, this interface converts high-precision digital quantity to by its communication port this analog quantity, and process switch 10 and loop ethernet 11 are delivered to central fire control point and be presented in instrument 16.Some manometric threshold values is also as the run function of fire-fighting stabilized pressure pump, fire pump and foam pump.
Electronic display at central fire control point is made up of man-machine interface (HMI) 15 and Displaying Meter group 16, can Real Time Observation to the state of the whole fire protection alarm system in chemical industry plant area and can Real Time Observation to pressure, the pump discharge pressure of fire fighting supply main pipe.Qin formula console 14 is made up of cabinet 17, some indicator lamps and some buttons 18, can Real Time Observation to the startup of the state of patrolling and examining, fire pump and the foam pump of the state of patrolling and examining of each fire pump and foam pump, the each electrically operated valve in malfunction Oil Tank Area and stop control button and start after the state etc. of response status, the open-close control button of each electrically operated valve and the position switch of each electrically operated valve.
In the time that fire-fighting occurs, the startup of each electrically operated valve of fire pump, foam pump and tank farm starts operation according to the program of fire-fighting operation, its start-up routine is stored in PLC 8, the corresponding start button 18 in the qin formula operation 14 that its function that starts this program can be manometric a certain threshold values or central fire control point.After the said equipment starts, the status signal of each equipment can be fed back to corresponding indicator lamp 18.
In fire protection alarm system 19, adopt two bus S, except alarm controller 20, smoke detector 21, heat detector 22, also use laser detector 23, Infrared Detectors 24 and visual fire detector 25.Use traditional detection means tool limitation at outdoor environment, and image fire detection device 25 has contactless detection feature, be not subject to the restriction of the environmental conditions such as high temperature, explosive, poisonous, high velocity air, accuracy rate and the response speed of fire alarm are greatly improved, it and other detector cross-reference, the interference of effectively having avoided various environmental background factors to produce.
Those skilled in the art is not departing under the condition of the definite the spirit and scope of the present invention of claims, can also carry out various amendments to above content.Therefore scope of the present invention is not limited in above explanation, but determined by the scope of claims.
