Abstract

A wireless alarm device for repository temperature and humidity monitoring comprises a main control module, a temperature sensing module, a humidity sensing module, a light-emitting diode (LED) display module, and a global system for mobile communications (GSM) module. The wireless alarm device for the repository temperature and humidity monitoring is characterized in that the main control module is respectively connected with the temperature sensing module, the humidity sensing module, the LED display module and the GSM module. The temperature sensing module obtains needed temperature value through measurement of currents, and the temperature value is converted into digital value through an analog to digital (A/D) converter and then is transmitted to the main control module to process. The humidity sensing module is arranged inside an oscillating circuit through a humicap, the variation of capacitance is converted into voltage frequency signals which are inversely proportional to the variation of the capacitance, then the voltage frequency signals are directly transmitted to the main control module to process, and the main control module transmits data to the LED display module for display. When the temperature and humidity is higher or lower than the value set by a user, the GSM module sends a message to a corresponding monitoring terminal like a mobile phone or a personal computer (PC), and informs repository staff to take measures in time.

Description

The wireless alarm device of warehouse temperature and humidity monitor
Technical field
The utility model relates to a kind of warehouse monitoring alarm device, the especially wireless alarm device of warehouse temperature and humidity monitor.
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 monitoring result be sent to corresponding monitor terminal (like mobile phone, PC) with short message mode through existing GSM network.
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, gsm module, it is characterized in that: the main control module is connected with TEMP module, humidity sensor module, display module, gsm 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, transfers 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; When temperature humidity is higher or lower than user's setting value, will be sent to corresponding monitor terminal (like mobile phone, PC) with short message mode through gsm module, in time notify the stock clerk to handle.
The beneficial effect of the utility model is, and is easy to use, measuring error is little, has advantages of high practicability.
Description of drawings
Fig. 1 is the theory diagram 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, gsm module 5, it is characterized in that: main control module 1 is connected with TEMP module 2, humidity sensor module 3, display module 4, gsm 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, transfers 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; When temperature humidity is higher or lower than user's setting value, will be sent to corresponding monitor terminal (like mobile phone, PC) with short message mode through gsm module, in time notify the stock clerk to handle.
What main control module 1 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.TEMP module 2 adopts integrated temperature sensor AD590, can obtain needed temperature value through the measurement to electric current.Humidity sensor module 3 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.LED display module 4 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.What gsm module 5 adopted is the TC35i wireless communication module of the up-to-date release of Siemens, and function and TC35 are compatible, and be compact to design.TC35i and GSM 2/2+ are compatible; Double frequency (GSM900/GSMl800) work has the RS232 data port, meets etsi standard GSM0707 and GSM0705; And be easy to upgrade to the GPRS module; This module integrates radio circuit and base band, to the user AT command interface of standard is provided, for data, voice and short message provide quick, reliable, safe transmission.
