Description of drawings
Fig. 1 is circuit block diagram of the present utility model.
The specific embodiment
The real-time fireproof monitoring of a kind of Intelligent cable ditch and automatic fire extinguishing system, comprise a plurality of temperature sensors 1 that are arranged on temperature sensing cable, its output is connected with the input of temperature measuring unit 2, the output of temperature measuring unit 2 is connected with the input of Data Centralized Processing device 3, the output of Data Centralized Processing device 3 is connected with automatic fire extinguisher 4, Data Centralized Processing device 3 and Surveillance center's communication.As shown in Figure 1.
As shown in Figure 1, the number of described temperature measuring unit 2 is at least 2, and its input is connected to few two temperature sensors 1.Described temperature measuring unit 2 is by RS485 communication bus and 3 communications of Data Centralized Processing device, and described Data Centralized Processing device 3 is to temperature measuring unit 2 power supplies.Described automatic fire extinguisher 4 adopts dry powder self-extinguishing device 4, and the output of automatic fire extinguisher 4 is connected by the input of feedback module with Data Centralized Processing device 3.Data Centralized Processing device 3 sends control signal, controls automatic fire extinguisher 4 and starts, fire extinguishing; The feedback module output feedback signal is to Data Centralized Processing device 3, and whether the 3 judgement fire extinguishings of Data Centralized Processing device run succeeded.Described Surveillance center is background server 5 and/or local monitor terminal 6, Data Centralized Processing device 3 by switch respectively with background server 5,6 communications of local monitor terminal.Temperature measuring unit 2 adopts up-to-date microelectric techniques, utilizes microcontroller to carry out the measurement of temperature, and construction is simple, and is reliable, the element advantage: without temperature float, non-maintaining; Based on bus structures, influence each other little; Carry out simultaneously multimetering, highly sensitive.Local monitor terminal can be networking client or short message alarm platform.
Below in conjunction with Fig. 1, the utility model is further described.
On the mode of cable temperature monitoring, the mode that adopts temperature sensor 1 to combine with temperature sensing cable.Temperature sensor can accurately be measured the temperature of cable connector, the keypoint part such as turn round, and temperature sensing cable can be monitored all fronts temperature of cable.The thermometric blind spot that both combinations can avoid adopting merely the mode of local measuring point to bring can effectively reduce Project Cost again.
Data Centralized Processing device 3 in native system adopts many algorithms as the criterion of warning and startup extinguishing device.Algorithm comprises: relative temperature, absolute temperature, temperature be amount, transverse temperature difference, temperature sensing cable judgement over time.
1) absolute temperature alarm is used for judging whether cable temperature has surpassed the maximum temperature that cable operation itself can bear.When cable arbitrary monitoring point temperature surpasses 60 ℃, system sends minor alarm; When cable arbitrary monitoring point temperature surpasses 83 ℃, system sends high severity alarm; For the setting of absolute alarm limit value, should be according to concrete type of cable, the maximum temperature values that be can bear by the normal operation of cable arranges;
2) relative temperature alarm is that cable temperature and the environment temperature that will record compares, and reaches certain limit value if the temperature of operation cable surpasses environment temperature, will report to the police.Relative temperature alarm mode can be avoided the impact that cable temperature caused because of seasonal climate change.Reach 10 ℃ when the cable monitoring temperature surpasses environment temperature, system sends the alarm of relative temperature secondary; Reach 20 ℃ when the cable monitoring temperature surpasses environment temperature, system sends the relative temperature Level 1Alarming.The alarm temperature threshold values can be adjusted as required.
3) Δ t temperature rise rate judgement refers in a certain regular time section, the monitoring point of a certain appointment, and temperature is measured over time.If in a certain regular time section, temperature increment reaches the threshold value of some settings, judge that for this reason the monitoring point temperature anomaly occurs and raises.It is 5 ℃/5Min that Δ t adjusts at present, according to result of the test, can escape cable and be downloaded on the lenient side heating under rated current, and action is reliable when electric current is larger in its steel armour.
4) transverse temperature difference judgement refers to simultaneously a plurality of different monitoring points of same cable be carried out the comparison of transverse temperature difference, sends alarm when the maximum of the temperature difference reaches a certain threshold values.
When breaking down, cable cause cable or cable head temperature to raise and when surpassing the alarm limit of setting, native system can send warning in a different manner, comprise network alarming client, note etc., and show the position that alarm point occurs and record the time that warning occurs, promptly and accurately guided maintenance and trouble shoot work.The alarm module of networking client ejects the alarm window immediately on client screen after the warning information that receives 3 transmissions of Data Centralized Processing device, comprise the various information of alarm, and the prompting user processes warning information immediately; The warning information of short message alarm platform receive data processing center, the alarm plan according to the user sets in advance sends alarm message according to different alarm types, alarm equipment to different related personnel.
The cable tunnel does not generally have personnel on the scene, no one's supervision when breaking out of fire, and fire development is rapid, and the burning of insulating materials can produce a large amount of toxic gases again, later stage fire extinguishing difficulty.Native system possesses automatic fire-extinguishing function, and when the fire alarm generation having been detected in system, system starts automatic fire extinguisher 4 immediately, and the very first time puts out a fire once, prevents that the intensity of a fire from enlarging.
Alarm parameters, alarm logging, sequence, printing of each control point etc. can be inquired about by system; Inquire about monitoring parameter, historical data, sequence, printing of each control point etc.; By the time inquire about, inquire about on a time period, by the monitoring station inquiry, by alarm inquiry etc., multiple condition query is provided.
In a word, the utility model is arranged on temperature sensor 1 on cable, can Real-Time Monitoring the temperature of the cables such as transformer station, switching station, and judge by 3 pairs of temperature of Data Centralized Processing device, can in time record, inquire about and Rapid Alarm automatically; Can see the temperature value of control point on computer screen, understand the information of control point, improve the reliability service ability of power system, improve maintenance efficiency, reduce accident potential, reduce maintenance cost and labour intensity, make from " ex-post analysis " and be transitioned into gradually " state judgement, self-extinguishing ".
