Description
Technical field
The invention belongs to wireless digital technical field, relate in particular to a kind of wireless temperature monitoring cruising inspection system and method.
Background technology
Industrial enterprise's switch cubicle thermometric mainly contains the modes such as optical fiber temperature-measurement, infrared measurement of temperature and video monitoring at present.And for low-voltage cabinet, particularly the general employing of drawer-type switch cabinet is the mode of patrolling and examining infrared measurement of temperature, but because the reason of structure there is no effective temperature Real-Time Monitoring means to drawout cubicle inside.And because low-voltage cabinet major part is all domestic, quality is relatively poor, so the Frequent Accidents that a lot of industrial enterprises drawer-type switch cabinet catches fire in recent years.For mesohigh cabinet, although cabinet generally carries optical fiber temperature-measurement and temperature can show in the instrument on cupboard surface, but cannot accomplish that temperature information is transmitted back to central station of floating dock in real time concentrates monitoring, so once and because mesohigh cabinet electric current all large screw do not tighten problems such as being just easy to cause bus bar heating damage.
Optical fiber temperature-measurement: optical fiber type temperature temperature measurer adopts optical fiber transmission delivery signal, and its temperature sensor is arranged on the surface of charged object, is connected with optical fiber between temperature measurer and temperature sensor.Optical fiber is easy to break, easily broken, non-refractory, and after accumulation dust, insulativity reduces, and the difficulty that connects up in cabinet is larger, and cost is high;
Infrared measurement of temperature: infrared thermoviewer can not penetrate object while measurement, measures internal unit therefore cannot see through cabinet door, can only open switch cubicle rear cabinet door and measure, and causes the bad measurement in a lot of positions;
Video monitoring and Smoke Detector: when breaking out of fire, under normal circumstances, fire is from switch board is inner, no matter generate heat, burn, smolder, be video monitoring or Smoke Detector, waits and observe or detect smog generation, often fire occurs, and loss causes.
Transformer case is general self configures temp measuring system, can in real time the temperature of each important measuring point in cabinet be presented on the display screen on cabinet face.But also there is following larger hidden danger:
The temp measuring system that transformer case carries easily breaks down;
Although the temperature in transformer case is presented on display screen, operations staff must go to see just to scene and can know, cannot guarantee that operations staff can recognize temperature variations at any time in strange land;
The temp measuring system carrying can only be measured real time temperature, but can not sharply change and provide warning the temperature of moment.
Summary of the invention
The object of the present invention is to provide a kind of wireless temperature monitoring cruising inspection system, be intended in time, accurately temperature parameter current intelligence and real-time information be reflected to supervisory computer system, in the time that temperature exceedes normal value, and alarm lessens the hidden dangers.
The present invention realizes like this, a kind of wireless temperature monitoring cruising inspection system by the remote read write line of RFID, wireless temperature measurement card, wireless communication module, control center, less radio-frequency patrol and examine card, hand-held is patrolled and examined PDA read write line and is formed, control center is made up of operator station, data server;
Described wireless temperature measurement card is arranged in the switch cubicle and transformer case that need to measure temperature, for the temperature of wireless measurement switch cubicle and transformer case;
The remote read write line of described RFID is used for the wireless device temperature information that wireless temperature measurement card records that reads, sending wireless communication module to by RS485 bus after information rough handling;
The wireless communication module of described production area is for passing to data the wireless communication module of data server end with 2.45GHZ microwave mode, the wireless communication module of data server end passes to data server after receiving data again, data server obtains after data processing, with graphics mode, relevant information is presented on monitored picture, and can analyzes and report to the police;
Described less radio-frequency is patrolled and examined card cloth and is placed on and patrols and examines a little, sends and patrols and examines signal for patrol and examine PDA read write line to hand-held.Further, described wireless temperature monitoring cruising inspection system make to be connected to network by level of factory LAN (Local Area Network) each have the use of authority can share per family information, by integrated note dispensing device, while having emergency condition, automatically relevant information is sent on managerial personnel's mobile phone by the mode of note.
Further, described monitored picture demonstrates each switch board measuring point temperature in real time by the mode of figure, and provide warning, warning arranges function, warning is divided into overtemperature alarm and transient temperature changes excessive warning, alarm temperature need to arrange according to user, the temperature that red expression monitors has exceeded the alarm temperature of setting, the temperature of double-clicking in picture shows, eject temperature alarming picture is set, user can be according to the needs change warning limit value of oneself, in the time that measurement temperature value exceedes warning limit value, will display alarm in picture, remind related personnel note and process.
Further, in described monitored picture, in switch board curve Administration menu, can carry out the inquiry of temperature real-time curve and Temperature history inquiry.
a kind of wireless temperature monitoring method for inspecting, concrete steps are as follows:
Lay less radio-frequency and patrol and examine card patrolling and examining a correct position, the hand-held PDA read write line of patrolling and examining of inspector, when entering after sensing range, by less radio-frequency being patrolled and examined to the information identification on card, judge the residing region of patrolling and examining, automatic spring is patrolled and examined item, inspector completes each patrolling and examining after patrolling and examining a little, preserve patrol record, patrol and examine after end, adopt wireless network and wireless radio-frequency, automatically each patrol record is uploaded in the database of cruising inspection system platform management end of data server, and can formation curve, form, and can call and inquire about at any time, in web browser, input cruising inspection system network address and just can enter log-in interface, in log-in interface, input username and password and enter patrolling and checking management system.
effect gathers
The beneficial effect of wireless temperature monitoring cruising inspection system of the present invention is as follows:
