Description
Technical field
The utility model relates to electronic information technology, is specifically related to a kind of vehicle-mounted removable velocity radar detector.
Background technology
Along with the develop rapidly of China's economic construction and improving constantly of living standards of the people, the number of on the road vehicle of going is significantly rising, and incident is that the break in traffic rules and regulations phenomenon is serious day by day, has caused great loss for people's lives and properties.In the break in traffic rules and regulations incident, drive over the speed limit and occupy very big ratio, as the saying goes " ten accident nine times fast ".At present, being used for limiting or sanction the drive method of behavior of hypervelocity in violation of rules and regulations, is to be that aid is monitored by radar meter and with camera installation (being commonly called as electronic eyes).Radar meter has characteristics such as carry easily, degree of accuracy is high, easy to use, and can carry out the speed of a motor vehicle at the volley and detect, deserve to be called " mobile electron police ", and be the equipment that tests the speed that China public security traffic control department extensively is equipped with.But there is drawback in the radar meter that uses at present: in use for some time, the phenomenon of frequency of occurrences skew and rate accuracy variation causes occurring false-alarm and surveys phenomenon with mistake easily.Therefore, be used for daily maintenance and detect the velocity radar detector of calibrating, not only requirement is big, and accurately durable high-quality more will be arranged.
At present the detection method of velocity radar detector is carried out in the laboratory: by the traffic administration personnel with radar meter one by one from the highway limit pole pull down; Be sent to special metrological service; Under lab detect by the professional with the degree of accuracy of detecting instrument to its transmission frequency and measurement of vehicle speed; Take a lot of work, time-consuming, efficient is low, cost is high.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose that the utility model adopts is to provide a kind of vehicle-mounted removable velocity radar detector, have save time, the saving of labor, cost low with the high characteristics of detection efficiency.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of vehicle-mounted removable velocity radar detector; Including the high-gain parabola antenna, broadband horn feed+waveguide excitation wave detector, frequency meter, the function generator that are arranged on the car body forms; Broadband horn feed+waveguide excitation wave detector is installed on the high-gain parabola antenna through bracing frame; Frequency meter links to each other with the excitation interface of broadband horn feed+waveguide excitation wave detector through concentric cable, and function generator links to each other with the detection interface of broadband horn feed+waveguide excitation wave detector through concentric cable.
The beneficial effect of the utility model is:
Because the utility model is arranged on high-gain parabola antenna, broadband horn feed+waveguide excitation wave detector, frequency meter, function generator on the automobile, adopt and move the method that detects, need not pull down radar meter, on highway, can reach testing goal.So both save manpower, improved the service efficiency of radar meter again.
During use; This vehicle-mounted removable velocity radar detector is installed on the automobile; Only need parabola antenna is aimed at radar meter, in the distance of 30-40 rice, just can carry out Performance Detection, needn't pull down radar meter and can on highway, accomplish detection the radar meter of installing on the highway collateral branch bar; Both save manpower, improved the service efficiency of radar meter again.
Description of drawings
The one-piece construction synoptic diagram of Fig. 1 the utility model.
The test philosophy synoptic diagram of Fig. 2 the utility model.
Embodiment
Below in conjunction with accompanying drawing the structural principle and the principle of work of the utility model are done further explain.
Referring to Fig. 1; A kind of vehicle-mounted removable velocity radar detector; Including the high-gain parabola antenna 1, broadband horn feed+waveguide excitation wave detector 2, frequency meter 3, the function generator 4 that are arranged on the car body forms; Broadband horn feed+waveguide excitation wave detector 2 is installed on the high-gain parabola antenna 1 feed as antenna through bracing frame; Frequency meter 2 is connected to the frequency of operation that is used to detect radar meter 5 on the excitation interface of broadband horn feed+waveguide excitation wave detector 2 through concentric cable, function generator 4 is connected to the rate accuracy index that is used to detect radar meter 5 on the detection interface of broadband horn feed+waveguide excitation wave detector 2 through concentric cable.
There is traffic control department that radar meter is removed earlier, delivers to then in the special laboratory and test.When test, the antenna of radar meter and the antenna of checkout equipment are installed relatively, and mounting distance is about 1.5 meters.When the frequency of operation of carrying out radar meter detects; Test antenna by electromagnetic horn+the waveguide excitation head is formed is connected on the frequency meter through concentric cable; With radar meter launched microwave signal; Receive through electromagnetic horn, microwave signal is transferred on the frequency meter via concentric cable, detect the frequency of operation of radar meter emission by frequency meter through the waveguide excitation head.When the rate accuracy of carrying out radar meter detects; The waveguide excitation head that will be connected with electromagnetic horn earlier changes the waveguide detecting head into; And then through concentric cable the waveguide detecting head is connected on the function generator, with radar meter launched microwave signal, receive through electromagnetic horn; Through the waveguide detecting head microwave signal is transferred on the function generator via concentric cable, detects the radar meter rate accuracy through function generator.
At present; Velocity radar commonly used operates mainly in two frequency ranges; Be X superhigh frequency band and Ka submillimeter region, this vehicle-mounted removable velocity radar detector can detect on highway the velocity radar of these two wave bands, and measuring distance is a 30-40 rice; Owing to adopted waveguide excitation wave detector, this detector can detect the frequency of operation and the rate accuracy index of radar meter simultaneously.
Referring to Fig. 2; Adopt the high-gain parabola antenna to realize the requirement of Distance Test; With the feed of electromagnetic horn+waveguide excitation wave detector as parabola antenna; The driving head interface of waveguide excitation wave detector is connected on the frequency meter through concentric cable, the detecting head interface of waveguide excitation wave detector is connected on the function generator through concentric cable, at last this test macro is installed on the automobile platform.Because adopted the parabola antenna of high-gain, measuring distance can reach 30-40 rice, on highway, just can realize the detection to the frequency of operation and the rate accuracy of radar meter like this.Radar meter need not dismounting when test; Directly parabola antenna is aimed at the microwave signal of radar meter with the emission of receiving radar knotmeter; Respectively this signal is transferred on frequency meter and the function generator through electromagnetic horn+waveguide excitation wave detector, can realizes detection so simultaneously the frequency of operation and the rate accuracy of radar meter.Because manpower had both been saved in the middle work of having removed the dismounting velocity radar from and having changed the waveguide detecting head, had improved the service efficiency of radar meter again.
