Abstract

The utility model relates to a warehouse humiture monitoring alarm device which includes a main control module, a temperature sensing module, a humidity sensing module, an LED display module, and an alarm module. The warehouse humiture monitoring alarm device is characterized in that the main control module is connected with the temperature sensing module, the humidity sensing module, the LED display module, and the alarm module respectively. The temperature sensing module acquires a required temperature value through measuring the current, and then the required temperature value is converted into a digital value through the A/D conversion, and next the digital value is transmitted to the main control module for processing. The humidity sensing module is arranged in an oscillation circuit via a humidity sensitive capacitor, and converts the capacitance change into a voltage frequency signal which is inversely proportional to the capacitance change, and then transmits the voltage frequency signal to the main control module for processing. The main control module transmits the data to the LED display module for display. When the temperature and the humidity are higher or lower than the settings of a user, the alarm module sends an alarm to notice a monitoring person to deal with.

Description

Warehouse temperature and humidity monitor alarm device
Technical field
The utility model relates to a kind of warehouse monitoring alarm device, especially warehouse temperature and humidity monitor alarm device.
Background technology
Protection against the tide, mildew-resistant, anticorrosion be the important content of warehouse routine work, it directly has influence on the serviceable life of stockpile, its matter of utmost importance is to strengthen the monitoring of temperature and humidity.Temperature that traditional method wastes time and energy, tests and humidity error are big.
Summary of the invention
In order to overcome the shortcoming of classic method; The utility model measuring accuracy is high; 0.5 ℃ of temperature detection scope-30 ~+50 ℃, measuring accuracy; Humidity Detection scope 10% ~ 100% RH, accuracy of detection 1 % RH., and humiture goes beyond the scope and can realize automatic alarm, in time notifies the monitor staff to handle.
The utility model solves the technical scheme that its technical matters adopted: warehouse temperature and humidity monitor alarm device comprises main control module, TEMP module, humidity sensor module, LED display module, alarm module, it is characterized in that: the main control module is connected with TEMP module, humidity sensor module, display module, alarm module respectively.The TEMP module can obtain needed temperature value through the measurement to electric current; Convert digital quantity to through A/D and send the main control resume module; The humidity sensor module places oscillatory circuit through humicap; Transfer the variation of capacitance to be inversely proportional to it voltage-frequency signal, directly send the main control resume module, the main control module is sent to the LED display module with data again and shows; Alarm module sends warning after temperature humidity is higher or lower than user's setting, in time notifies the monitor staff to handle.
The beneficial effect of the utility model is, and is easy to use, measuring error is little, automatic alarm, has advantages of high practicability.
Description of drawings
Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structural drawing of the utility model.
Embodiment
In Fig. 1; Warehouse temperature and humidity monitor alarm device comprises main control module 1, TEMP module 2, humidity sensor module 3, LED display module 4, alarm module 5, it is characterized in that: main control module 1 is connected with TEMP module 2, humidity sensor module 3, display module 4, alarm module 5 respectively.TEMP module 2 can obtain needed temperature value through the measurement to electric current; Converting digital quantity to through A/D send main control module 1 to handle; Humidity sensor module 3 places oscillatory circuit through humicap; Transfer the variation of capacitance to be inversely proportional to it voltage-frequency signal, directly send main control module 1 to handle, main control module 1 is sent to LED display module 4 with data again and shows; Alarm module 5 sends warning after temperature humidity is higher or lower than user's setting, in time notifies the monitor staff to handle.
In Fig. 2, the TEMP module adopts integrated temperature sensor AD590, can obtain needed temperature value through the measurement to electric current.The humidity sensor module adopts the HS1100 capacitive transducer, in circuit constitutes, is equivalent to a capacitor element, and its electric capacity increases along with the increase of survey air humidity.This humicap is placed 555 oscillatory circuits, transfer the variation of capacitance to be inversely proportional to it voltage-frequency signal, can directly be gathered by computing machine.What the main control module adopted is the 89C51 single-chip microcomputer; Because 89C51 does not have inner ROM, so the program memory address of expansion is 0000 H ~ FFFFH, the needs of taking into account system; We expand to 4K EPROM with the program storage of 89C51, adopt 2764 as rom chip.The LED display module is to utilize the serial port of 89C51 to be display interface device, uses the way of output of the serial port mode 0 of 89C51, at the external shift register 74LS164 of serial port, constitutes display interface device.The prompting that alarm module exceeds the bound of humiture in temperature and humidity measurement is reported to the police, and adopts buzz to report to the police.
