When in evaporating dish, moisture is less, when having influence on measurement, it is accomplished by evaporating dish moisturizing, the present embodiment is based on automatic control system, collecting in evaporating dish after the information of the water yield, send to background control system, background control system according to set threshold decision the need of moisturizing, if desired, then control water charging system work, moisturizing in evaporating dish, meanwhile, the information of rate of water make-up is acquired by corresponding device, is then forwarded to background control system, calculating for evaporation capacity, it is ensured that the later stage calculates the accuracy of the result of evaporation capacity.
For drain pipe, drain pipe one end is connected on evaporating dish, the other end is connected with pump, its effect is, when hypervolia in evaporating dish, when influencing whether to measure, by drain pipe, evaporating dish is carried out draining, draining action is by pump control, and this pump can be separately provided, it is also possible to share a pump with the water charging system in embodiment 5.
In another embodiment, drain pipe is not connected to pump, and one end connects evaporating dish, and the other end extends to the outside of equipment, arranges controlled valve on drain pipe, it is generally preferable that be electromagnetic valve, in order to remotely control.
When excess moisture in evaporating dish, when having influence on measurement result, as: overflowing, now, background control system then can control drainage system work, discharges the water yield in evaporating dish, meanwhile, discharges the water yield and should also be as measurement and transmit to background control system.Wherein, in evaporating dish, runny standard can be arranged a standard value by background control system, and the value that is above standard then represents excess moisture, needs to discharge.
On the basis of the above, the present embodiment is also integrated with automatic control system, to realize evaporation is measured the long-range control of various parts action.This system includes background control system, information collecting device, communicator；Wherein, background control system is used for receiving, processing data message, assigns corresponding control instruction；Information collecting device mainly includes gathering the device of weighing system reading, gathering the device of the device of the water yield in evaporating dish, the device of collection filling pipe rate of water make-up, collection drain pipe displacement, said apparatus all can adopt the sensor of correspondence to realize, as: LOAD CELLS, flow transducer, liquid level sensor etc..Communicator, for realizing information, the order transmission of evaporating between measurement system and information collecting device and background control system.The information that information collecting device gathers includes the rate of water make-up information of evaporating dish and the weight information of the interior water yield thereof, the displacement information of drain pipe, filling pipe and the water level information etc. of the water yield in evaporating dish.Communicator can be wire communication device, it is also possible to be radio communication device.
Based on said structure, the process that vaporizer is automatically obtained measurement is as follows:
(1) within a measurement cycle, first background control system controls the first action actuating mechanism and is placed on by evaporating dish on the first weighing system and weighs, and obtains original weight information；
(2) background control system controls the first action actuating mechanism evaporating dish departs from the first weighing system, makes evaporating dish enter evaporation duty；
(3) after evaporation after a while, evaporating dish is placed on the first weighing system by background control system the first control action actuator weighs, and obtains real-time weight information；Wherein, the time can be the preset value arranged in background control system, is used for determining the measurement cycle；
(4) background control system is according to measuring the primary data information (pdi) and real time data information that obtain, calculates and obtains evaporation capacity, completes to measure.
Above-mentioned control, measurement all can pass through remotely operation, it is not necessary to staff is in the action, and according to the measurement cycle arranged, it may be achieved measurement secondary more than a day, efficiently avoid the drawback that prior art manually completes to test.
Two, pluviometer
As Figure 4-Figure 6, pluviometer adopts weight method to realize the measurement to rainfall equally, pluviometer mainly includes pluviometer assembly, the second action executing system and the second weighing system, and the equal integrated installation of the said equipment is in a rainfall case, and the parts that need to fix then are fixed on the base plate of rainfall case.Realizing adopting weight method that rainfall is measured by said structure, its principle is as follows: quality G when pluviometer is started working1, after a period of time, quality is G2, rainfall value Y=(G in this period2-G1)/(ρ S), wherein ρ is the density of water, and S is the area of pluviometer raingauge receiver mouth.This utility model, compared with existing pluviometer, not only realizes more convenient, and precision is higher.
