Abstract

The utility model relates to an intelligence tent with full angle infrared monitoring function, its core warning circuit are by human PIR, the digital logic module, and boost module, modules such as high frequency impulse production module are carried out effective circuit connection and are constituted to the circuit only need use ordinary 5V voltage to drive. This technical scheme is reliable, and low cost can realize full angle infrared monitoring and warning for the people who has a rest in the tent can feel at ease to have a rest.

Description

A kind of intelligent tent with full angle infrared monitoring function

Technical field

This utility model relates to a kind of tent with full angle infrared monitoring function, belongs to Leisure Sports articles for use technical field.

Background technology

Along with the raising of people's living standard, outdoor camping is increasingly becoming a kind of welcome Novel leisure and spends a holiday mode, and outdoor tent also increasingly receives the favor of more consumer. The advantages such as outdoor tent has simple and convenient, lightly durable, easy to carry. Existing many patented products about Multifunctional tent at present, mostly it is simple from the consideration of energy angle, solar panel and tent combination is utilized then to realize several functions, cost performance is relatively low, if " a kind of Multifunction outdoor tent " (application number 201320411288.2) is to be provided with solar panel on the tarpaulin of account outside, illuminator, charging device it is provided with in interior account, the functions such as illumination, mobile phone charging are melted into a whole, and the complicated tent product cost of some other function is high, limited by practical.

Utility model content

Outdoor camping when people's rest inside tent it may be noted that less than the situation of outside, for instance the property safety around tent even may meet with external attack when people sleeps in tent. The utility model proposes a kind of simple and practical intelligent tent, it is possible to realize full angle infrared monitoring and warning, people can feel at ease to have a rest in tent, does not worry that stranger is close.

Technical scheme:

There is the tent of full angle infrared monitoring function, include tarpaulin, support bar, it is characterised in that also include the control circuit, the alarm that are placed in tent and be hung with the support bar composition of three human body infrared detection modules at the outer infrared isolated material at top of tent, tent top. Described three human body infrared detection modules are mounted laterally with the angle being mutually 120 degree, and the detection angular field of view of infrared detection module is more than 120 degree, less than 180 degree. Described alarm is connected digital logic module by human body infrared detection module successively, connects boost module afterwards, then connects high-frequency impulse generation module again, and last connected with passive buzzer is such forward to be connected to form. Described human body infrared detection module is HC-SR501. Described digital logic module is or door digital logic chip 74LS32. Described boost module is 2N2219A. Described high-frequency impulse generation module is LYLY-CM2.

Beneficial effect

1) this utility model can detect the active situation of tent stranger in real time, time out of doors, it is possible to the people for having a rest in tent provides real-time guarantee of feeling at ease.

2) this utility model is practical reliable and with low cost, uses identical with common tent, and can provide real-time monitoring, alarming.

Detailed description of the invention

Intelligence tent, as it is shown in figure 1, use strut to put up a tent, is then opened alarm device in tent and is switched, and Fig. 2 is this device schematic diagram. It is embodied as follows:

The infrared spacer bar of infrared detection module it is mounted with in the outer middle, top of tent, then with the alarm of homemade 2m Du Pont line (in order to be convenient for changing) connection tent inside installation, (main body is by digital logic module, connect boost module afterwards, then connecting high-frequency impulse generation module again, last connected with passive buzzer is such forward to be welded on circuit boards).

When there being people to move, human body infrared detection module is by detecting perception human body infrared information, then signal is directly output to be arranged on the input pin of digital logic module ' or ' door of tent inside control circuit with the level of about 3V, and (this chip includes 4 group 2 and inputs 1 output or door, need to carry out two signals that detection module is carried ' or ' later result and carry out ' or ' computing again with another signal, and final one level signal of output). TTL standard logic levels will be produced as the high-frequency impulse generation module on switching voltage direct driving circuit plate afterwards after the signal multiple tube boost module that direct-coupled audion is constituted in the control circuit boosting of ' or ' gate circuit output. High-frequency impulse generation module produces high-frequency signal drive installation and sends chimes of doom at the passive buzzer of tent inside afterwards.

When have outside tent people near time, human body infrared detection sensor detects signal, by OR circuit, detection signal is delivered to audion boosting gate circuit (as shown in Figure 3) and become 5V unidirectional current, power supply is enabled directly to high-frequency impulse circuit for generating, then produce pulse signal and drive passive buzzer warning, thus the people having a rest in being embodied as tent points out the function of warning. Wherein, human body infrared detection module HC-SR501 detects the activity of tent stranger in real time, belongs to a kind of passive type infrared detecting device. Or door digital logic chip 74LS32 records multiple sensor signal simultaneously, as long as there being a detection sensor to have signal it is necessary to send control signal for follow-up warning circuit. The THE BOOST SWITCHING CIRCUIT that boost module 2N2219A is made up of two audions, direct-coupling pulse generator power supply below. High-frequency impulse generation module LYLY-CM2 frequency and the adjustable squarer of dutycycle, during employing NE555, basis set becomes ICIC, receives boost module power supply and enables, drives the passive buzzer reported to the police. Passive buzzer KC12065V electromagnetic AC buzzer, receives high-frequency impulse and produces the chimes of doom of characteristic frequency.
