Abstract
This invention relates to a humidity detection method for domestic refuse. Wherein, inserting two electric probes into different positions of the target, forcing n exterior voltage U1 between probes, and measuring directly resistance of the garbage to obtain its moisture. Compared with prior art, This invention can get entire garbage moisture without extra sensor to reduce cost greatly.
Description
Technical field
The present invention relates to the humidity detection method of a kind of humidity detection method, particularly a kind of house refuse.
Background technology
Traditional humidity detection method is, utilize a humidity sensor, obtain humidity value by its voltage of exporting corresponding to humidity, the output characteristic curve of conventional humidity sensor is a linear growth trend, and promptly the humidity sensor output voltage continuously changes along with the variation of humidity.
The improvement of existing different moisture levels detection technique all is conceived to how further improve accuracy of detection, as application number is that the Chinese invention patent application " being used to detect the apparatus and method of humidity " of ZL99125980.7 (publication number is CN1259664A) promptly discloses a kind of Humidity Detection of high Precision Detection that realizes and puts and method, this humidity detector comprises that is used to export the continually varying current detection section along with the variation of air humidity, and substep output circuit that is used for voltage that the voltage transitions of partly exporting from Humidity Detection is converted with output for the voltage that progressively changes with each predetermined voltage range, the method that this device adopts promptly is: humidity sensor produces the voltage that progressively changes with each predetermined moisture range along with air humidity, and utilizes the level of this voltage to determine humidity.
But, be that traditional humidity sensor or improved high precision humidity sensor all are not suitable for the Humidity Detection to house refuse, its reason has two: one, and humidity is inhomogeneous everywhere owing to house refuse, and humidity sensor generally can only be placed on a certain location, its testing result can only reflect the situation of check point, and can not reflect the overall humidity level of house refuse well; The 2nd, the Humidity Detection of house refuse need not too high precision, and general need reflect that wet, moderate, dried three kinds of moisture conditions can meet the demands, and therefore the moisture detector of extra increase has increased the cost of Humidity Detection undoubtedly.
Summary of the invention
Technical matters to be solved by this invention is the humidity detection method that a kind of new house refuse is provided at above-mentioned prior art present situation, and it has with low cost and can reflect the characteristics of house refuse overall humidity level.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the humidity detection method of this house refuse is, directly two conductive probes are placed two diverse location places of house refuse to be measured respectively, by between two conductive probes, applying a voltage that adds, directly measure the impedance of house refuse to be measured and obtain the humidity of house refuse to be measured, the low more then humidity of impedance is big more.
The impedance of described house refuse to be measured can be measured by the following method, get the sampling resistor (R0) of a known value, it is connected between one of them conductive probe and the ground, another conductive probe then connects the external power supply with certain voltage (U1), by recording the voltage (U0) on the sampling resistor, promptly know the impressed voltage (Ux=U1-U0) on the conductive probe, at the impedance that can calculate house refuse to be measured according to the law of partial pressure (Ux/Rx=U1/ (Rx+R0)) (Rx=R0 * (U1-U0)/U0).
Two relative tertiary locations of described house refuse to be measured can be in the house refuse to be measured up and down relatively, about relatively or the front and back relative position.
For the house refuse to be measured that is stored in the cavity volume, described two conductive probes can be set directly on this cavity volume two opposite inner walls.
The moisture condition of having surveyed house refuse for only having needed to ungird is super wet, wet, moderate, more dried, super one of dried five kinds measurement occasion, determine these five kinds of moisture conditions critical voltage value of corresponding sampling resistor (R0) respectively by the method for test earlier, then with the voltage at the actual sampling resistor that records (R0) two ends and this five critical voltage values relatively, the moisture condition that can determine house refuse to be measured is above-mentioned five kinds any.
Compared with prior art, the present invention dexterously the overall impedance by direct measurement house refuse mode and directly obtain its overall humidity, need not to adopt extra humidity sensor, thereby saved the detection cost greatly.
Description of drawings
Fig. 1 is the circuit theory synoptic diagram of the embodiment of the invention.
Fig. 2 is the circuit scheme of installation of the embodiment of the invention.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As Fig. 1, shown in Figure 2, a kind of humidity detection method of house refuse directly places two conductive probes 1 respectively two diverse locations of treatment trough 2, on the opposite edges that contiguous this house refuse to be measured of the diverse location at two conductive probe places is taken up space.By between two conductive probes, applying a voltage U x who adds, by lead 3 conductive probe 1 and process chip 4 are coupled together, directly measure the impedance Rx of house refuse to be measured, thereby, obtain the humidity of house refuse to be measured according to the big more rule of the low more then humidity of impedance.
The impedance of house refuse to be measured is measured by the following method, get the sampling resistor R0 of a known value, it is connected between one of them conductive probe and the ground, another conductive probe then connects the external power supply with certain voltage U1, by recording the voltage U 0 on the sampling resistor, promptly know the impressed voltage Ux=U1-U0 on the conductive probe, can calculate the impedance Rx=R0 of house refuse to be measured * (U1-U0)/U0 according to law of partial pressure Ux/Rx=U1/ (Rx+R0) again.
The humidity detection method of this kind house refuse, for the moisture condition that only needs to understand house refuse to be measured is super wet, wet, moderate, more dried, super one of dried five kinds measurement occasion, determine these five kinds of moisture conditions critical voltage value of corresponding sampling resistor R0 respectively by the method for test earlier, then with the voltage at the actual sampling resistor R0 two ends that record and this five critical voltage values relatively, the moisture condition that can determine house refuse to be measured is above-mentioned five kinds any.
