Description
Technical field
The utility model is specifically related to a kind of portable CO gas leakage alarm.
Background technology
CO is a kind of gas of colorless and odorless, because the haemoglobin in it and human body has the affinity of height, so, when it is inhaled into after in body, make people occur tired out, breathe hard, feel sick and the ill symptoms such as to feel dizzy, even can cause dead because of anoxic when sucking too much in body.Meanwhile, CO is also a kind of inflammable and explosive hazardous gas, therefore, carries out volume fraction detection timely and accurately and warning becomes the requisite work ensureing masses' life security and national wealth safety to the indoor CO in room; There is the problems such as accuracy of detection is low, type of alarm is single in current gas leakage detection alarm device, brings a lot of trouble to use.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, provides a kind of portable CO gas leakage alarm.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable CO gas leakage alarm, comprise CO to gather and signal processing unit, alarm unit, power supply unit, main control unit, GSM unit, LCD display unit, push-button unit and charhing unit, CO gathers and is connected main control unit respectively with signal processing unit, alarm unit, power supply unit, GSM unit, LCD display unit, push-button unit and charhing unit.
The utility model also has some technical characteristics like this:
Main control unit adopts MSP430F135 singlechip chip.
CO gathers and adopts three electrode sensors to carry out signals collecting with signal processing unit.
Push-button unit comprises Energy control button, arranges button, increases progressively button and the button that successively decreases, the short switch on time realizing backlight of Energy control button, long by the switch realizing power supply.
GSM unit adopts SIM900A note chip.
The utility model has effect useful as follows:
The utility model is reasonable in design, easy to use, and convenient, high precision, low-power consumption, multi-mode are reported to the police, and built-in external power supply and charging module automatically switch, in real time display electricity and remind charging, has good application prospect.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 is that CO of the present utility model gathers and signal processing circuit unit figure;
Fig. 3 is push-button unit circuit diagram of the present utility model;
Fig. 4 is charhing unit circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of portable CO gas leakage alarm, comprise CO to gather and signal processing unit 1, alarm unit 2, power supply unit 3, main control unit 4, GSM unit 5, LCD display unit 6, push-button unit 7 and charhing unit 8, CO gathers and signal processing unit 1, alarm unit 2, power supply unit 3, GSM unit 5, LCD display unit 6, push-button unit 7 is connected main control unit 4 respectively with charhing unit 8, main control unit adopts MSP430F135 singlechip chip, CO gathers and adopts three electrode sensors to carry out signals collecting with signal processing unit, push-button unit comprises Energy control button, button is set, increase progressively button and the button that successively decreases, the short switch on time realizing backlight of Energy control button, long by the switch realizing power supply, GSM unit adopts SIM900A note chip.
Principle of work: user arranges the phone number of CO alarm threshold value and GSM message alarm unit by the push-button unit that button forms, when CO volume fraction is higher than CO alarm threshold value, LED glimmers, and hummer sends chimes of doom, and GSM unit sends warning information on the mobile phone of setting simultaneously.For ease of using, instrument power source adopts rechargeable lithium battary, and user can charge to instrument with common adapter or USB easily.Avoid because of the not enough cisco unity malfunction of instrument electricity, instrument shows the electricity of battery in real time simultaneously, and when electricity sends warning lower than during operating voltage, reminding user charges.
Charhing unit: when input voltage power down, CN3052A enters the sleep pattern of low-power consumption automatically, current drain is less than 3 μ A.CHRG pin output low level, represents that charging is carried out.When voltage is lower than 3V, charger small area analysis carries out precharge to battery; When cell voltage is more than 3V, charger adopts constant current mode to current charges, and charging current is determined by the resistor RISET between ISET pin and GND; When cell voltage is close to battery-end modulation voltage, charging current reduces gradually, and CN3052A enters constant-voltage charge pattern.When charging current is reduced to charging end threshold value, charge cycle terminates, and CHRG end exports high-impedance state, represents that charge cycle terminates, and charging end threshold value is 10 % of constant-current charge electric current.
