Preferably, as shown in Figure 2, a kind of fault detection method that the embodiment of the present invention provides also comprised before S102:
The load that the output of this radio frequency link is connected with this radio frequency link, comprising the systematic evaluation of radio frequency link to detecting pattern, disconnects, and the input of described radio frequency link and output is connected to form loop by S101a, control section;
The isolation that S101b, control section control this loop is greater than the gain of this loop, to avoid the signal in loop to form positive feedback, and causes concussion.
Wherein, S101, S101a, S101b there is no tandem, that is, according to random order, can perform this three steps.
For application scenarios one, namely the hardware device D in radio frequency link and load are disconnected, the output of hardware device D is the output of this radio frequency link, and by the input of hardware device A, namely one end that when radio frequency link normally works, hardware device A is connected with signal source, with the output of hardware device D, one end that when namely radio frequency link normally works, hardware device D is connected with load, be connected, thus make radio frequency link form loop.
The preset input power forming transmitter in the radio frequency link of loop can be different from the preset input power of transmitter in the radio frequency link not forming loop, and the default error originated from input forming transmitter in the radio frequency link of loop can be different from the default error originated from input of transmitter in the radio frequency link not forming loop.
Formed after loop at radio frequency link, which the hardware device emitting radio frequency signal no matter in radio frequency link, each hardware device in radio frequency link is detectable hardware device, and transmitter also can receive signal; But because control section controls input and the output isolation of transmitter, therefore, the signal that transmitter receives can not have influence on the signal that this hardware device exports, therefore, when judging whether transmitter is out of order, the power of the signal that it receives can be detected, or, arrange transmitter for self preset input power and/or default error originated from input, the power of the signal that transmitter is received and this transmitter are less than the default error originated from input of this transmitter for self for the absolute value of the difference of the preset input power of self.

S102a1, control section, according to the corresponding relation of hardware device in testing circuit and radio frequency link, determine the testing circuit that in radio frequency link, each detectable hardware device is corresponding;
S102a2, control section control the testing circuit corresponding with detectable hardware device and detect the power of the signal that this detectable hardware device exports, and the power of signal that the previous stage hardware device that the control testing circuit corresponding with the previous stage hardware device of this detectable hardware device detects this detectable hardware device exports.
Suppose in application scenarios one, control section connects four testing circuits, is respectively testing circuit 1, testing circuit 2, testing circuit 3 and testing circuit 4, wherein, the power of the signal that testing circuit 1 exports for detection hardware device A, the power of the signal that testing circuit 2 exports for detection hardware equipment B, the power of the signal that testing circuit 3 exports for detection hardware equipment C, the power of the signal that testing circuit 4 exports for detection hardware equipment D, if hardware device B launches detection signal, then control section can obtain the power of the signal that hardware device B receives by the power controlling the signal that testing circuit 1 detection hardware device A exports, the power of the signal that hardware device C receives is obtained by the power controlling the signal that testing circuit 2 detection hardware equipment B exports, the power of the signal that hardware device D receives is obtained by the power controlling the signal that testing circuit 3 detection hardware equipment C exports, the power of the signal that hardware device A receives is obtained by the power controlling the signal that testing circuit 4 detection hardware equipment D exports.
After the input of radio frequency link and output are connected to form loop, for the hardware device of in the hardware device in radio frequency link except transmitter, this hardware device can be arranged to identical for the default power output of this transmitter with the previous stage hardware device of this hardware device for the preset input power of this transmitter, and this hardware device can be arranged to identical for the default output error of this transmitter with the previous stage hardware device of this hardware device for the default error originated from input of this transmitter.
Therefore, as shown in Figure 6, when needing to detect the power of the signal that all detectable hardware devices export in radio frequency link, during position with localizing faults, S102a2 specifically comprises: control section, according to the transmission sequence of detection signal, controls the power that the testing circuit corresponding with each detectable hardware device detects the signal that each detectable hardware device exports successively.
For application scenarios one, if hardware device B launches detection signal, then first control section controls the power of the signal that testing circuit 2 detection hardware equipment B exports, then the power of the signal that testing circuit 3 detection hardware equipment C exports is controlled, then control the power of the signal that testing circuit 4 detection hardware equipment D exports, finally control the power of the signal that testing circuit 1 detection hardware device A exports.
