Embodiment
Among Fig. 1, telemetering equipment 1 is installed in the test output terminal port 2 of wired TV amplifier 3, telemetering equipment 1 detects tested equipment state by the test output terminal port 2 of wired TV amplifier 3, with the mode of wireless telecommunications and testing staff's hand-held receiving system communication, the testing staff reads the equipment under test state parameter by hand-held receiving system.Wired TV amplifier is equipped with three ports usually, be respectively amplifier in mouth 4, amplifier output port 5 and amplifier test output terminal mouth 2, the physical connection mode of above-mentioned amplifier port is a standard radio frequency F type socket, the connectivity port of telemetering equipment 1 is a standard radio frequency F type plug, fix firm and reliable connection and the weight that can bear telemetering equipment 1 by the rotation screw thread between F type plug, the socket.
Among Fig. 2, each telemetering equipment all has a unique address number to distinguish mutually with other telemetering equipments, when the testing staff does not detect, all telemetering equipments all are in accepting state, not wireless when the testing staff does not detect to external world's emission, all telemetering equipments all are in accepting state, not to external world's emission wireless signal.When testing staff's desire detects a certain equipment, at first, send sense command then with the hand-held receiving system of address number input of the telemetering equipment of this equipment correspondence.All telemetering equipments in hand-held receiving system communication context all will be received this instruction, but the telemetering equipment that address number conforms in having only address number and detecting instruction just can be made a response to this, after telemetering equipment receives the command signal of hand-held device transmission, this telemetering equipment detects the equipment under test that self connected earlier, comprise device power supply (DPS), apparatus output signal level etc., then the testing result data are sent back to hand-held receiving system together with self address number, after whole process finishes, enter again and wait for the wireless telemetering coomand mode.
Among Fig. 3, hand-held receiving system 6 is by RS-232 interface and microcomputer 8 communications, and RS-232 interface is the standard peripherals interface of present microcomputer, every microcomputer all is equipped with two serial line interfaces that meet rs-232 standard, the physical connection mode that the RS-232 interface of hand-held receiving system adopts is the DB-9F type socket of standard, the physical connection mode that the RS-232 interface that microcomputer provides adopts also is the DB-9F type socket of standard, and the two connects by standard serial port distich cable 8.Hand-held receiving system has data storage function, the result who at every turn tests can be stored in self memory.This memory is a nonvolatile memory, and data can not lost when hand-held receiving system power down.
