The invention aims to overcome the defects of the prior art and provides an oil rig electric control room based on a thermal imaging temperature monitoring system, and the invention is further detailed by combining the embodiment.
Examples
As shown in figure 1, the petroleum drilling machine electric control room based on the thermal imaging temperature monitoring system comprises an electric control room, and a thermal imaging temperature monitoring system, an electric control room PLC and an audible and visual alarm which are installed in the electric control room.
In this embodiment, the thermal imaging temperature monitoring system includes a thermal imaging detection probe, a thermal imaging transmission module, an integrated controller, an audible and visual alarm, and a background analysis platform.
The thermal imaging detection probe is connected with the thermal imaging transmission module, and the thermal imaging transmission module is connected with the integrated controller, so that detected signals are transmitted to the integrated controller.
The integrated controller is respectively connected with the PLC of the electric control room, the background analysis platform and the audible and visual alarm.
Thermal imaging detection probes are arranged at a plurality of positions in the electric control room, and the thermal imaging detection probes correspond to the thermal imaging transmission modules one to one. Specifically, according to key and key electrical equipment needing to be monitored, thermal imaging detection probes and thermal imaging transmission modules, such as an inverter cabinet and the like, can be installed at different positions.
The thermal imaging detection probe detects the temperature of each monitoring point in real time and transmits the temperature to the integrated controller in real time through a communication interface of the thermal imaging transmission module. When the data received by the integrated controller is a signal that the temperature exceeds a critical value, an audible and visual alarm signal is sent out to prompt field personnel that high temperature abnormality occurs in the room; meanwhile, the integrated controller sends a signal to the PLC of the electric control room, the PLC controls corresponding equipment, the working temperature of the equipment is reduced, personnel participation is not needed in the whole process, and automatic monitoring is realized.
In this embodiment, the audible and visual alarm can also be provided with a plurality of audible and visual alarms, which correspond to the thermal imaging detection probes one by one, so that the controller sends a signal to the corresponding audible and visual alarm, and thus, a worker can directly know which detection point exceeds the standard according to the audible and visual alarm.
The background analysis platform and the integrated controller are communicated by adopting a network interface, the temperature of each monitoring point can be displayed in real time, and the temperature is stored in a database form so as to be displayed, analyzed and historically inquired conveniently.
When the temperature abnormality of the electric control equipment is identified, besides the artificially set critical value is compared, the temperature early warning critical values of various electric control equipment can be corrected in time through background analysis software, and the thermal model of the electric control equipment during operation is accurately analyzed, so that the accuracy and timeliness of the temperature abnormality identification are improved, and safe and reliable cooling measures are taken.
Taking the most important thermal imaging temperature monitoring of the main frequency converter of the drilling winch as an example, the software logic flow of the controller is as follows:
input (detected by the thermal imaging detection probe of the system): (1) a frequency converter I2t model (aiming at a squirrel-cage three-phase variable-frequency speed-regulating asynchronous motor) references a current r 0068; (2) power cell temperatures (r0037.[ x ], [0] = inverter, [1] = insulating layer, [2] = rectifier, [3] = blast, and [4] = inside the power cell.
The parameters can be set: (1) a frequency converter I2t model P0612= squirrel-cage three-phase variable-frequency speed-regulating asynchronous motor; (2) rated current of the power unit under different working systems, P0205, 0= working system containing heavy overload; 1= the work system with light overload, and the winch needs to select the work system with heavy overload; (3) power unit I2t overload alarm threshold P0294;
and (3) outputting: (1) the overload rate (r0036) of the power unit calculated by the I2t model; (2) alarming that the I2T model frequency converter power unit is overloaded A07805; (3) a downtime F30005; (4) the power-down output control P0290 is 0, namely, the output current or the output frequency is reduced; the value is 1, no reduction occurs, and tripping is performed when the overload threshold value is reached; a value of 2, reducing the output current or the output frequency or the pulse frequency; the value is 3, decreasing the pulse frequency.
The logic flow is as follows: (1) importing r0068 into a model selected according to P0612 and P0205, calculating to obtain r0036, if r0036=100%, F3005=1, and outputting fault shutdown; (2) if r0036> P0294 setting, alarm A07805 will be output; (3) if the relevant temperature of r0037 exceeds the limit value, P0290 action is triggered, and measures are immediately taken to reduce the load so as to achieve the purpose of reducing the temperature.
The system can also use a manual mode, the integrated temperature controller can also give out sound and light alarm, but the PLC does not take measures such as reducing equipment load, controlling air conditioner refrigeration, turning off equipment power supply and the like, and at the moment, necessary cooling measures are manually observed and taken.
And a cooling system is further arranged in the electric control room, and the PLC of the electric control room controls the cooling system to start to cool the electric control room.
The invention is well implemented in accordance with the above-described embodiments. It should be noted that, based on the above structural design, in order to solve the same technical problems, even if some insubstantial modifications or colorings are made on the present invention, the adopted technical solution is still the same as the present invention, and therefore, the technical solution should be within the protection scope of the present invention.
