The utility model is rational in infrastructure, and is easy to use, can monitor concentration of oxygen in the underground cable layer exactly; Guarantee that oxygen concentration is more than security value (s); Improve the security of patrolling and examining greatly, and can when the appearance abnormal conditions in the underground cable layer, in time alerting signal be sent to control terminal; Go site disposal before reminding the monitor staff to send the staff as early as possible, guaranteed the safety of Operation of Electric Systems.
Description of drawings:
Fig. 1 is the theory structure block diagram of the utility model.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the utility model is set forth in detail.
Shown in figure, the utility model comprises microprocessor, ambient conditions pick-up unit, display device, ventilation unit, operation keyboard, warning device and radio communication unit; Ambient conditions pick-up unit, display device, ventilation unit, operation keyboard, warning device and radio communication unit link to each other with microprocessor respectively.
Said ambient conditions pick-up unit comprises oxygen concentration pick-up unit, flue gas concentration pick-up unit, humidity detector and temperature-detecting device, and oxygen concentration pick-up unit, flue gas concentration pick-up unit, humidity detector and temperature-detecting device link to each other with microprocessor respectively.
Described ventilation unit is a blower fan.Said display device is a LCDs.Said oxygen concentration pick-up unit, flue gas concentration pick-up unit, humidity detector and temperature-detecting device are respectively oxygen concentration sensor, flue gas concentration sensor, humidity sensor and temperature sensor.
Microprocessor is used to coordinate to control the work between each device, the unit, comprises receiving the button control information that operation keyboard passes over; Display device is used for the respective detection data that display environment situation pick-up unit is sent here; Ventilation unit is used for improving the oxygen concentration in the underground cable layer to ventilating in the underground cable layer; Operation keyboard is used to import corresponding control information; Warning device is used for when abnormal conditions occurring in the underground cable floor, sending corresponding alarm sound; Oxygen concentration pick-up unit, flue gas concentration pick-up unit, humidity detector and temperature-detecting device are respectively applied for the oxygen that detects in the underground cable layer, concentration and the humidity and the temperature of flue gas, and send corresponding information to microprocessor; Operation keyboard is used to import corresponding control information; Radio communication unit is used for corresponding warning message is sent to control terminal.
During use; The oxygen concentration sensor, flue gas concentration sensor, humidity sensor and the temperature sensor that are located in the underground cable layer can be sent to the survey data in the microprocessor in real time; Microprocessor can compare data of sending here and secure setting, and corresponding data is delivered to the display device demonstration; When the oxygen density value in the underground cable layer of sending here was lower than setting numerical value, microprocessor sent the low alerting signal of oxygen concentration through warning device, and caution is patrolled and examined the staff and do not gone into; Send control signal to ventilation unit simultaneously; The control fan starting ventilates, and sets numerical value when above when the oxygen concentration in the underground cable floor returns to, and little processing is sent to warning device and stopped alerting signal; Send control signal to ventilation unit simultaneously, the control blower fan stops operating; When the flue gas concentration of flue gas concentration sensor in the underground cable layer exceeds standard; Send the flue gas signal that exceeds standard to microprocessor, microprocessor is received behind the signal through warning device and is sent the flue gas alerting signal that exceeds standard, and sends the flue gas alerting signal that exceeds standard through radio communication unit to control terminal simultaneously; Go to patrol and examine before reminding the monitor staff in time to send the staff; Avoid occurring major accident, influence electric system and normally move, when after treatment; The flue gas concentration that the flue gas concentration sensor arrives just often; Send the flue gas concentration normal signal to microprocessor, microprocessor is received behind the signal to send to warning device and is stopped alerting signal, sends the flue gas normal signal through radio communication unit to control terminal simultaneously; When the humidity in the underground cable layer of sending here exceeds standard; Microprocessor sends control signal to ventilation unit; The control fan starting ventilates, and reduces the humidity in the underground cable layer, sets numerical value when following when the humidity in the underground cable floor returns to; Little processing is to sending control signal to ventilation unit, and the control blower fan stops operating; When the Temperature numerical in the underground cable layer of sending here exceeded standard, microprocessor sent the temperature exceeding standard alerting signal through warning device, sent the temperature exceeding standard alerting signal through radio communication unit to control terminal simultaneously; Go to patrol and examine before reminding the monitor staff in time to send the staff; Avoid occurring major accident, influence electric system and normally move, when after treatment; Temperature in the detected underground cable layer of temperature sensor just often; Send the temperature normal signal to microprocessor, microprocessor is received behind the signal to send to warning device and is stopped alerting signal, sends the temperature normal signal through radio communication unit to control terminal simultaneously.
