Abstract

The utility model relates to an exhaust gas collection and transmission device for automobiles, which relates to the technical field of wireless transmission. With the popularization of automobiles, the pollution caused by exhaust gas emission thereof arouses great attentions, and increase of the automobile number presents the problem of exhaust gas emission significantly. As for the examination of automobile exhaust gas, manual methods are still adopted for data collection, transmission and statistic, which are very complex, inconvenient and inaccurate. Aiming at overcoming the defects, the utility model adopts a scheme which integrates exhaust gas examination and wireless data transmission. The utility model has a probe for measuring the ingredients of automobile exhaust gas, and the probe is connected with a wireless data transmission module which transmits the data from the probe to a communication module of a central database in a GPRS mode. The utility model has the characteristics of fast transmission, handy appearance, reliable performance, easy operation, etc.

Description

The vehicle exhaust collecting transmitter

Technical field

The utility model relates to field of wireless transmission, and especially vehicle exhaust detects the data acquisition transmission.

Background technology

The check of vehicle exhaust at present adopts fixed point to detect mostly, directly be presented on the probe, manual input forms data sheet, this way had both been brought inconvenience to the car owner, be unfavorable for unified data management again, more influenced relevant department and found the vehicle that exhaust emissions exceeds standard fast timely, limited renovation dynamics greatly about vehicle exhaust.And artificial manual input formation form, very loaded down with trivial details, speed is slow, and also causes mistake easily, to the networking formation obstacle of data.No matter so car owner or relevant department all wish to change detection and the data processing method that this falls behind.Along with science and technology development, the check of vehicle exhaust also must be faster, more accurate, and its data transmission also should be timely, and is open.

Summary of the invention

The purpose of this utility model provides a kind of dependable performance, and is convenient to operation, quick, simple and direct vehicle exhaust collecting transmitter.

The technical solution of the utility model is as follows: the vehicle exhaust collecting transmitter has near the vehicle exhaust of exhaust port probe, the vehicle exhaust probe by output interface with the vehicle exhaust data can be linked to each other the wireless data transfer module that data send on the internet by the GPRS wireless network that moves.

Wireless data transfer module has singlechip microprocessor CPU, CPU respectively with tail gas data-interface change-over circuit, data sending and receiving circuit, data storage circuitry, the tail gas sound light alarming circuit that exceeds standard, tail gas data and number-plate number display circuit, keyboard circuit is connected with power circuit.The vehicle exhaust probe links to each other with interface conversion circuit.

The outlet of vehicle exhaust alignment probe tail gas, after treating that exhaust gas component detects end, by translation interface related data is uploaded to wireless data transfer module, after wireless data transfer module is waited for the current license plate number of outside input, the vehicle exhaust assay of current vehicle can be uploaded on the internet simultaneously printable come out after clicking transmission button.

In wireless data transfer module, interface conversion circuit can upload the data to CPU with the interface and the CPU compatibility of tail gas probe; Keyboard circuit can be input to the license plate number of current vehicle in the wireless data transfer module; Then current license plate number and tail gas related data are stored in the data storage circuitry; And show by display circuit; If current tail gas exceeds standard, can send sound and light alarm by warning circuit; Clicking the transmission button by keyboard circuit simultaneously uploads to current data and alerting signal on the internet by the data transmit-receive circuit; Power circuit generator required voltage when voltage is lower than operating voltage, has the low pressure alarming function, reminding user to replace battery, the supply regular power of assurance device.This shows that to the utlity model has transmission quick, profile is small and exquisite, dependable performance, characteristics such as easy and simple to handle.
