Abstract
The utility model relates to a device for testing the sensitivity of a remote controller receiver, which is characterized by comprising a receiver, a power supply, an ampere meter, an oscilloscope and a remote controller which converts an internal current-limiting resistor into an adjustable resistor; the power output end is connected with a power supplying end of the receiver by the ampere meter; the output end of the receiver is connected with the input end of the oscilloscope; and the remote controller is arranged at the opposite surface of the receiver. By limiting the transmitting power of the remote controller, the device judges the sensitivity of the receiver according to the signals received by the receiver, thus reducing the space of the test and improving the production efficiency.
Description
Technical field
The utility model relates to a kind of device of testing the telepilot receiver sensitivity, is applicable to the sensitivity that detects receiver.
Background technology
Existing industry is to the test of remote controller signal decay; whether the general maximum distance test telepilot that all is operator stands in this telepilot support has effect to the receiver that will test; but because telepilot is highly sensitive; interfere with the test of other machine through regular meeting; and need space on a large scale; and detection efficiency is extremely low, has wasted bigger human and material resources.
Summary of the invention
In view of the deficiency of above-mentioned technology, the purpose of this utility model provides a kind of device of testing the telepilot receiver sensitivity, and it can be implemented in the short distance space and effectively receiver be carried out sensitivity test, has marketable value preferably.
For achieving the above object, the utility model adopts following scheme to realize: a kind of device of testing the telepilot receiver sensitivity is characterized in that: comprise receiver, power supply, reometer, oscillograph and inner current-limiting resistance is changed into the telepilot of adjustable resistance; Described power output end is connected with the feeder ear of receiver by reometer, and the output terminal of described receiver is connected with the oscillograph input end; Described telepilot is located at the receiver right opposite.
The utility model is not only simple in structure, need not complicated peripheral circuit, and detect effective, to testing environment require low, disturb for a short time, can effectively enhance productivity, have marketable value preferably.
Description of drawings
Fig. 1 is the utility model structural principle synoptic diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides a kind of device of testing the telepilot receiver sensitivity, it is characterized in that: comprise receiver, power supply, reometer, oscillograph and inner current-limiting resistance is changed into the telepilot of adjustable resistance; Described power output end is connected with the feeder ear of receiver by reometer, and the output terminal of described receiver is connected with the oscillograph input end; Described telepilot is located at the receiver right opposite, and (this distance can be 30 ~ 50cm).During test, regulate the adjustable resistance of telepilot, observe reometer and oscillograph, normal as the working current of receiver, and the waveform that observation oscilloscope shows, as waveform high level 〉=4.5V, low level≤0.5V and waveform are clear, stable, and front and back are along vertical, do not rock, illustrate that then this receiver sensitivity is qualified, but the resistance of described modulation resistance this moment is the resistance of the former current-limiting resistance of telepilot, also is the resistance that the telepilot tool will be revised.Here be noted that in ensuing test we only need to utilize the telepilot that configures the current-limiting resistance resistance, go to test the sensitivity of each equipment receiver, significantly reduced detection time, and have detect effective, to testing environment require low, disturb advantages such as little.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
