This causes the following problems in the process of optical machine testing: firstly, there are many types of complete machines that can be used as signal generators in the market, and in the testing process, different types of optical machines need different types of complete machines to correspond; secondly The price of using the whole machine as a signal generator is very expensive, and a large number of signal generators need to be used in the optical-mechanical testing process of an optical projector, which means that multiple projectors are needed as a signal generator; The circuit and mechanical structure in the whole instrument are very complicated. If the whole machine is to work uninterruptedly for 24 hours, its reliability is relatively poor, and it is also difficult to maintain; finally, the whole machine needs to light the bulb during work. The heat is very large, which is not conducive to environmental protection

Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0029] like figure 1 As shown, the present invention provides a signal generator for optical-mechanical testing of projectors, comprising a group of substrates, selecting a substrate 1 matching the optical-mechanical of the projector to be tested from the above-mentioned group of substrates, Such as SONY X-225 and the power board 2 matching the substrate 1, such as SONY APS-310 to form a signal generation system, in which the power board 2 provides a stable voltage source for the substrate 1, such as providing the DC 6.2V voltage source required by the substrate 1 , while providing an enable signal of a certain voltage of the substrate 1, such as a DC3.3V voltage signal. The functional interface in the substrate 1 includes a command input terminal 3, a data input terminal 4 and an output termin...

The invention discloses a signal generator which is used for tests of an optical machine of a projector. The signal generator comprises a set of substrates. One substrate which is matched with the optical machine to be tested is selected from the substrates, and the substrate and a power panel matched with the substrate constitute a signal generation system. The order input end of the substrate of the signal generation system is connected with external control orders. The data input end of the substrate of the signal generation system is connected with an external video signal source. The output end of the substrate of the signal generation system is connected with the optical machine to be tested. The power panel of the signal generation system is connected with an external power source. The signal generator is simple in structure and convenient to operate. When the signal generator is used for tests of optical machines of different projectors, the substrate just needs to be replaced, so that the signal generator is high in universality, and a user can conveniently manages the signal generator in daily life.
Description
technical field [0001] The invention relates to a signal generator, in particular to a signal generator used for testing an optical machine of a projector. Background technique [0002] At present, in the production process of an optical projector, the optical-mechanical inspection of the projector usually requires the entire projector as a signal generator. This causes the following problems in the process of optical machine testing: firstly, there are many types of complete machines that can be used as signal generators in the market, and in the testing process, different types of optical machines need different types of complete machines to correspond; secondly The price of using the whole machine as a signal generator is very expensive, and a large number of signal generators need to be used in the entire optical-mechanical testing process of an optical projector, which means that multiple projectors are needed as a signal generator; The circuit and mechanical structure...
