Description
Technical Field
The utility model relates to the technical field of agricultural machine test detection, in particular to a novel wireless portable GPS speed tester.
Background
The earliest conventional measuring method is to measure a distance with a measuring tape, then the vehicle to be measured enters a measuring area at a stable speed, the running time of the vehicle in the measuring area is recorded by a stopwatch, and the running speed of the vehicle is obtained by dividing the distance by the time. The measuring mode has low accuracy, high requirements on measuring personnel and instruments, difficulty in ensuring that the measured vehicle advances at a constant speed, high requirements on road surfaces and environmental conditions, and time and labor waste because of the need of measuring for multiple times to obtain approximate values for reference. The second measurement method is to use a photoelectric sensor (photoelectric head) and a secondary instrument for measurement, and has the defects that the photoelectric sensor is not well installed on a machine to be measured, and a special receiving disc is required to be firstly manufactured for one machine, so that the connection is inconvenient. Moreover, the photoelectric sensor adopts a 12V power supply, the power of the bulb is not too high, the phenomenon of unstable or interrupted signals is easily generated in places with strong light or uneven roads, and a lot of troubles are brought to the detection process. With the maturity and popularization of the GPS technology in recent years, the GPS sensor is also applied to agricultural machinery detection, and has the advantages that the GPS sensor is small in size and convenient to install on a detected vehicle, the sensor with high working frequency can be selected, the measurement error can reach within 0.5km/h, the current measured value can be displayed in real time by receiving satellite signals, and the current measured value is displayed on a secondary instrument through a data transmission line or a wireless transmitting device, so that the current speed is measured. However, the existing detection instrument is still connected with a secondary instrument through a data line through a GPS speed signal, and a large number of data lines and instruments are required to be carried for simple speed measurement or braking test, so that the detection instrument is very inconvenient and has potential safety hazards. And these three kinds of measuring methods are when carrying out braking deceleration measurement test, all very are difficult to control and begin the braking instantaneous point, and need install the secondary instrument on the vehicle under test when braking test, because agricultural machine operating space is very narrow and small, the secondary instrument is difficult to the safe placement, and the unable real-time tracking of testing personnel, bring very big degree of difficulty for detecting, cause detection efficiency very low, the most important huge potential safety hazard that still exists, there are two kinds of transmission methods simultaneously: one is GPRS transmission and the other is WIFI transmission. GPRS transmission needs to be additionally provided with a GPRS module at a GPS sensor end, the transmission distance can be far enough, but the real-time performance is poor, the refreshing frequency of the GPS sensor is 1-20Hz, and even reaches 30Hz, the refreshing frequency of GPRS data transmission far cannot meet the requirement, if a GPRS special line is opened, application and communication with a communication department are needed, the cost is quite high, and therefore the data transmission cannot meet the existing test requirement. WIFI can realize real-time transmission, and transmission speed is fast, but as is known to all, WIFI transmission distance is short, and the signal is very poor when having the shelter, so also be unsuitable for experimental detection.
In summary, the present invention provides a novel wireless portable GPS speed tester to solve such problems.
