The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is intelligent patrol detection fire protection warning coordinated control system schematic diagram of the present utility model, outside having basic fire protection warning and interlock function, also comprises: can be to the fire pump of the fire water supply equipment of chemical industry plant area, the control appliance that foam pump is patrolled and examined automatically.This control appliance by the high-tension switch cabinet 1 that starts fire pump and foam pump, patrol and examine switch board 2, and cabinet in frequency converter 3, transformer 4, patrol and examine controller 5, vacuum contactor 6 and optical fiber control circuit 7 automatically and form.This equipment has 2 kinds of duties: non-fire-fighting work state and fire-fighting work state.When non-fire fighting state, patrol and examine program by the Clock enable of patrolling and examining of patrolling and examining controller 5 automatically, it makes the alternating current of a lower frequency of frequency converter 3 outputs, 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 makes fire pump rotate with a low rotating speed, make every fire pump and foam pump move 5-10 minute so so, one by one.Periodically like this patrol and examine automatically, can thoroughly solve the dead problem of rust that fire pump and foam pump need not cause for a long time.Carrying out above-mentionedly when patrolling and examining automatically, if when fault such as power supply phase shortage, under-voltage, motor overload, short circuit takes place, then can send alarm signal immediately.Optical fiber control circuit 7 is a kind of safety circuit modes that adopt when the control high-tension circuit, namely can finish control logic, does not have the apprehension of danger of high voltage level again.When fire fighting state, the startup command that can be sent by central fire control point or fire pump, foam pump are started immediately and move with rated speed by the threshold values that presets that Pressure gauge provides, provide fire water supply and foam with specified lift and flow, finish the fire extinguishing of tank farm.After the fire-fighting event finishes, manual-lock fire pump and foam pump.Fire pump or foam pump are set at 2 usefulness one usually and are equipped with or the using and the reserved, if fire pump or foam pump are moved failure of pump when fire-fighting moves, then stand-by pump can drop into automatically.
Can be formed by PLC 8 and motor-driven valve distribution box 9 control appliance that each electrically operated valve equipment of oil storage tank field is patrolled and examined automatically, as shown in Figure 3.By in the programmable logic controller (PLC) (PLC) 8 patrol and examine the program that Clock enable is patrolled and examined electrically operated valve, this program makes each valve contactor action separately in the motor-driven valve distribution box 9, make the electrically operated valve in the tank farm open one by one-closed set, after each electrically operated valve action, position switch on the electrically operated valve can provide valve open or closed state synchronously, this state feeds back to PLC 8 one by one, and the qin formula operating desk 14 that is sent to central fire control point is again shown.
Each equipment is presented at equipment state on the electronic display 13 and Qin Shi operating desk 14 of central fire control point with the duplex signaling linkage manner with central fire control point with, switch 10 and ring-type Ethernet 11 in real time by PLC 8, also corresponding each interlock object that passes to of instruction that simultaneously the fire-fighting center is sent.
Can indicate the Pressure gauge group 12 of fireproof water tube net state to be formed by the Pressure gauge on the pump discharge that is installed in each fire pump and foam pump, fire fighting supply main pipe, the arm in real time.The force value of each Pressure gauge indication is given mould/number conversion interface in the PLC 8 with analog quantity, this interface converts this analog quantity to high-precision digital quantity by its communication port, and process switch 10 and loop ethernet 11 are delivered to central fire control point and be presented on the instrument 16.Some manometric threshold values is also as the startup 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, but but Real Time Observation arrives the state of the whole fire protection alarm system of chemical industry plant area and pressure, the pump discharge pressure that Real Time Observation arrives the fire fighting supply main pipe.Qin formula console 14 is made up of cabinet 17, some indicator lamps and some buttons 18, but 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, each electrically operated valve of malfunction oil storage tank field and stop control button and start after the open-close control button of response status, each electrically operated valve and the state of the position switch of each electrically operated valve etc.
When fire-fighting takes place, the startup of each electrically operated valve of fire pump, foam pump and tank farm is according to the program start operation 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, can feed back corresponding indicator lamp 18 to the status signal of each equipment.
In fire protection alarm system 19, adopt two bus S, except alarm controller 20, smoke detector 21, heat detector 22, also used 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 characteristics, be not subjected to the restriction of environmental conditions such as high temperature, explosive, poisonous, high velocity air, accuracy rate and the response speed of fire alarm have greatly been improved, it intersects with other detector uses the interference of having avoided various environmental background factors to produce effectively.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite spirit and scope of the present utility model of claims.Therefore scope of the present utility model is not limited in above explanation, but determined by the scope of claims.
