Fig. 2 is the structural representation of the utility model control device.
Embodiment
Referring to Fig. 1, the utility model comprises evaporation tub, waterproof pump box, moisturizing bucket, sensing device and control device, in waterproof pump box, be provided with unwatering pump and small pump, evaporation tub connects the input port of waterproof pump box internal drainage pump by drainpipe, evaporation tub connects the delivery outlet of small pump in waterproof pump box by filling pipe, the delivery outlet of unwatering pump carries out outer draining by pipeline, the input port of small pump connects moisturizing bucket by pipeline, sensing device connects evaporation tub by communicating pipe, and control device communicates to connect respectively waterproof pump box and sensing device.
Sensing device comprises detecting chamber and ultrasonic sensing probe, detecting chamber is interior by connecting water body in evaporation tub communicating pipe, and in water body liquid level and evaporation tub, liquid level is consistent in detecting chamber, ultrasonic sensing probe is arranged in detecting chamber and for passing through water body liquid level in ultrasonic power Real-Time Monitoring detecting chamber.
Control device comprises PLC controller, wireless signal transmitting device, and the output terminal of PLC controller connects the control end of waterproof pump box, and the input end of PLC controller connects ultrasonic sensing probe, wireless signal transmitting device and the communication connection of PLC controller.
In actual use, by the water surface in detection E601 evaporation tub, having changed evaporation from water surface measures.And when the lowest water level line that the liquid level in evaporation tub surpass to be measured and maximum water level, automatically carry out moisturizing and draining, guarantee that the liquid level in evaporation tub remains in place.By the unified evaporator operation of controlling of core PLC controller.Every day, while arriving the time point of measuring, the central processing unit sending controling instruction of PLC controller inside was given evaporation measuring system, and evaporation measuring system obtains instruction rear drive sensor the liquid level of evaporation tub is surveyed.Sensor is passed signal back to core control system after having surveyed, the input end of PLC controller receives outside for detection of the measured rainfall amount signal of rainfall amount instrument simultaneously, through calculating water-head, benefit water discharge and the rainfall amount of twice measurement in certain time period, just can calculate evaporation capacity in the period, determine whether simultaneously and need moisturizing or draining.In order to improve the resolution of evaporator, the present embodiment adopts the pinpoint function of ultrasonic sensor to complete the detection of evaporation tub water surface variable quantity.In order to reduce the impact of evaporation water body top wind and sunshine, utilize communicating pipe that a detecting chamber is set on evaporation tub side, being consistent in the water body liquid level in detecting chamber and evaporation tub, the volume of detecting chamber water body is far fewer than the water body volume in E601, to reduce the impact of detecting chamber water body on water body in E601 evaporation tub.Detecting chamber is for the detection of ultrasonic probe, and by communicating pipe the water of E601 evaporation tub being caused in detecting chamber, ultrasonic probe is surveyed to water surface transmitting ultrasound wave from the bottom of detecting chamber.The signal of detection is transferred to PLC controller.When in evaporation tub, water body is too much because evaporation reduces, ultrasonic probe transfers to PLC controller by water level information, PLC control small pump in waterproof pump box from moisturizing bucket to moisturizing in evaporation tub.When making because of rainfall in evaporation tub that water body is too much, PLC controls unwatering pump in waterproof pump box from outwards draining in evaporation tub, to guarantee that in evaporation tub, the water surface remains at normal level.Measured evaporation capacity is sent to remote server to carry out data acquisition by PLC from wireless signal transmitting device.
