Description

Silo amasss hot intelligent controller

Technical field

The utility model relates to silo equipment, and particularly a kind of silo amasss hot intelligent controller.

Background technology

Silo is a closed container that door, window are arranged, and certain space is arranged after grain installs, and summer high-temperature rises the temperature of silo through roof, wall; Because the rising of cereal temperature, the humidity in the warehouse increases, and grain can go mouldy in the environment of high temperature, high humility for a long time; Traditional solution is to open ventilation equipment before leaving offices, and close ventilation equipment after the working the next morning again, and so not only labour intensity is big; And energy consumption is high, and waste is big, and the quality of grain also can not get ensureing.

Summary of the invention

To above-mentioned situation; For overcoming the defective of prior art; The purpose of the utility model just provides the long-pending hot intelligent controller of a kind of silo, can effectively solve existing grain temperature, moisture control unit and use trouble, labour intensity is big, energy consumption is big and handling cost is high problem.

The technical scheme of its solution is; Comprise casing, temperature sensor, humidity sensor and code switch; Single-chip microcomputer is arranged in the casing, first temperature sensor, second temperature sensor, first humidity sensor and second humidity sensor that link to each other with single-chip microcomputer are housed on the wall box, there is seven-segment numeric indicator and the code switch that links to each other with single-chip microcomputer the casing upper surface; The control follower that links to each other with single-chip microcomputer is housed on the casing, and single-chip microcomputer links to each other with power supply through plug with seven-segment numeric indicator.

The utility model novel structure is unique, and is safe and convenient to use, is the innovation on grain temperature and the humidity conditioner.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain.

Provide by Fig. 1, Fig. 2; The utility model comprises casing, temperature sensor, humidity sensor and code switch; In the casing 1 single-chip microcomputer is arranged; First temperature sensor 2 that links to each other with single-chip microcomputer, second temperature sensor 3, first humidity sensor 4 and second humidity sensor 5 are housed on casing 1 sidewall; There is the seven-segment numeric indicator 6 and code switch 7 that links to each other with single-chip microcomputer casing 1 upper surface, and the control follower 8 that links to each other with single-chip microcomputer is housed on the casing 1, and single-chip microcomputer links to each other with power supply through plug 9 with seven-segment numeric indicator 6.

In order to guarantee result of use, on said casing 1 sidewall hand switch 10 is housed, control follower 8 links to each other with power supply through manual switch 10, and when closing hand switch 10, the utility model begins automatic work; When opening hand switch 10, the utility model quits work, and gets into the manual control state.

The model of said single-chip microcomputer is STC89C52RC, and the model of seven-segment numeric indicator 6 is SM410564.

Said control follower 8 is made up of two relays and an A.C. contactor.

The operating position of the utility model is; Control follower 8 is connected in the exhaust fan circuit of silo; First temperature sensor 2 and first humidity sensor 4 are placed on the silo outside; Detect the outer temperature and humidity of silo, second temperature sensor 3 and second humidity sensor 5 are placed in the silo, detect the temperature and humidity in the silo.

The temperature of setting in the silo is T _{The storehouse}, humidity is S _{The storehouse}, to set beginning ventilation temperature difference be Δ T _Ventilate, to set the humidity difference that begins to ventilate be Δ S _Ventilate, the outer temperature of silo is T _Gas, humidity is S _Gas, set that to stop the ventilation temperature difference be Δ T _{Stop to ventilate}, setting the humidity difference that stops to ventilate is Δ S _{Stop to ventilate}Unlocking condition according to blower fan: T _{The storehouse}-T _Gas>=Δ T _Ventilate, S _{The storehouse}-S _Gas>=Δ S _VentilateThe condition of closing is: T _{The storehouse}-T _Gas＜Δ T _{Stop to ventilate}, S _{The storehouse}-S _Gas＜Δ S _{Stop to ventilate}

According to the program of working out in advance; Utilize single-chip microcomputer to replace artificial judgment and operation, the temperature and humidity in testing environment temperature, humidity and the storehouse is caught ventilating occasion automatically automatically; Automatically judge ventilation effect, single-chip microcomputer opens and closes automatically vent window and the long-pending calorifier of row through A.C. contactor 8.

The operating position of seven-segment numeric indicator 6 is, plug 220 alternating current earlier after, show that 000,011,112,222 3,333 4,444 5,555 6,666 7,777 8,888 9999 stop at 9999; Pull up 220 alternating current then; Plug the plug of two-way temperature, humidity sensor, plug 220 alternating current again, at this moment begin to show 0,000 1,111 2,222 3,333 4,444 5,555 6,666 7,777 8,888 9999; 84.684.60.0003.00.5, change normal process of measurement then over to.

DISPLAY ORDER is:

First displays temperature data: the temperature value in the warehouse;

Second displays temperature data: the temperature value outside the warehouse;

The 3rd displays temperature data: the temperature=difference outside the temperature-warehouse in the warehouse;

The 4th displays temperature data: what just begin to start ventilation to the temperature value in the preset warehouse greater than the temperature outside the warehouse;

The 5th displays temperature data: the temperature value in the preset warehouse drops to than high how much just the stopping of external temperature to ventilate;

Humidity value outside the 6th demonstration warehouse;

The 7th display time data: the time that record ventilates, each number is 13.2 seconds;

The interior humidity value in the 8th demonstration warehouse;

The 9th display system information;

Nine circulations show

The effect of code switch 7 is:

1, is used for setting cereal temperature and is higher than ambient temperature satisfied temperature of ventilating of how many times, the scope 0-7.5 of setting ℃, in 0-7.5 ℃ of scope, avoid grain can not amass dew;

2, be used for setting ventilate cereal temperature after a period of time and drop to the temperature that stops to ventilate than ambient temperature high how many times, the scope 0-7.5 of setting ℃;

3, the humidity that is used for setting in the warehouse can be ventilated less than atmospheric humidity; The scope 0-60RH% that sets, atmospheric humidity stops to ventilate greater than 96RH%, accomplishes the optimal ventilation seizure on opportunity by above-mentioned work; The work of realization gap reaches efficient, energy-conservation and the reduction handling cost;

The utility model mechanism is unique, does not need existing ventilation equipment are transformed, and does not need manually-operated, does not need to safeguard that cost is low, and measuring accuracy is high, and fiduciary level is high, energy-conservation, operating cost is low, easy to use directly perceived, be the innovation of the long-pending hot ventilation equipment of silo.
