The embodiment of the present invention provides a kind of detection method of power information acquisition system fault, due in practical engineering application, more lay particular emphasis on whether to break down to communication channel to the fault detect of a communication system and detect, and do not require to know whether terminal equipment breaks down, therefore, can only whether normally detect the communication channel of a communication system.

As shown in Figure 3, checkout gear determination communication channel is deposited after the failure, and the schematic flow sheet of the detection method of the power information acquisition system fault that the embodiment of the present invention provides, comprising:

S201, checkout gear trigger concentrator and the first ammeter carries out carrier communication.

S202, checkout gear calculate the carrier test success rate of the first ammeter.

Concrete, as shown in Figure 4, S202 specifically comprises: S202a-S202c.

S202a, detection device records concentrator and the first ammeter carry out in the process of carrier communication, the carrier wave received quantity of the carrier wave received quantity of concentrator and the carrier wave quantity forwarded of concentrator and the first ammeter and the carrier wave quantity forwarded of the first ammeter.

S202b, checkout gear calculate the carrier wave transmission success rate of the first ammeter and the carrier wave successful receiving rate of the first ammeter.

Wherein, the carrier wave of the first ammeter sends the ratio that success rate is the carrier wave received quantity of concentrator and the carrier wave quantity forwarded of the first ammeter, and the carrier wave successful receiving rate of the first ammeter is the ratio of the carrier wave received quantity of the first ammeter and the carrier wave quantity forwarded of concentrator.

Exemplary, the process that detection device records concentrator and the first ammeter carry out carrier communication is:

First, checkout gear obtains the initial carrier wave quantity forwarded a1 of the CCO of concentrator and initial carrier wave received quantity a2, and the initial carrier wave quantity forwarded b1 of the STA of the first ammeter and initial carrier wave received quantity b2; Then, start test of checking meter for N time, after N test of checking meter terminates, the CCO being recorded in concentrator in the process of test of checking meter for N time stops carrier wave quantity forwarded c1 and stops carrier wave received quantity c2, and the STA of the first ammeter stops carrier wave quantity forwarded d1 and stops carrier wave received quantity d2 in the process of N test of checking meter; Again according to a1, a2, b1, b2, c1, c2, the carrier wave that d1, d2 calculate the STA of the first ammeter sends success rate and carrier wave successful receiving rate, wherein, it is (c2-a2)/(d1-b1) that the carrier wave of the STA of the first ammeter sends success rate, and the carrier wave successful receiving rate of the STA of the first ammeter is (d2-b2)/(c1-a1).

S202c, checkout gear calculate the carrier test success rate of the first ammeter according to the carrier wave transmission success rate of the first ammeter and the carrier wave successful receiving rate of the first ammeter.

Concrete, the carrier test success rate of the first ammeter can be the carrier wave of the first ammeter send success rate and the carrier wave successful receiving rate of the first ammeter be weighted average after value, or the carrier test success rate of the first ammeter can be a value less in the carrier wave transmission success rate of the first ammeter and the carrier wave successful receiving rate of the first ammeter.

First, initial data traffic volume e1 and the initial data quantities received e2 of the STA serial ports of the first ammeter is obtained; Then, start test of checking meter for N time, after N test of checking meter terminates, the STA being recorded in the first ammeter in the process of test of checking meter for N time stops serial ports and sends the amount f1 of data and the amount f2 of STA termination serial ports reception data; Calculate the successful receiving rate of the serial ports of the STA of the first ammeter again according to e1, e2, f1, f2, wherein, the successful receiving rate of the serial ports of STA is (f2-e2)/(f1-e1).

S302b, checkout gear calculate the serial ports test success rate of the first ammeter.

Wherein, the serial ports test success rate of the first ammeter is the ratio of the data quantity forwarded of the data receiver quantity of the serial ports of the first ammeter and the serial ports of the first ammeter.

The serial ports test success rate of the first ammeter is the successful receiving rate of the serial ports of the first ammeter.Because the manufacturer of ammeter is different, the difference of the indexs such as the sensitivity of ammeter, is inconvenient to add up to the transmission success rate of the serial ports of ammeter, therefore, herein using the serial ports test success rate of the successful receiving rate of the serial ports of the first ammeter as ammeter.

Further, first ammeter is being carried out in the process of serial ports test, the success rate of testing of checking meter for N time can also be obtained, namely N academic probation is carried out to the first ammeter, read the successful number of times of data and account for the ratio of number of times of checking meter for N time for test success rate of checking meter, this test success rate of checking meter also can represent whether the communication channel of the first ammeter breaks down intuitively, and whether the serial communication channel of determination first ammeter that concrete serial ports test success rate then can be concrete breaks down.

If the serial ports test success rate of S303 first ammeter does not meet second pre-conditioned, then the serial communication channel between concentrator and the first ammeter breaks down.

When carrying out serial ports test to the first ammeter, and after obtaining the serial ports test success rate of the first ammeter, by the serial ports of the first ammeter test success rate and second pre-conditioned in the second preset value compare, if the serial ports test success rate of the first ammeter is less than the second preset value, then illustrate that the communication channel of the first ammeter breaks down, concrete, the serial communication channel of the first ammeter breaks down.

If the carrier test success rate of the first ammeter does not meet first pre-conditioned, or the serial ports test success rate of the first ammeter does not meet second pre-conditioned, then the communication channel of the first ammeter breaks down.Concrete, when the carrier test success rate of the first ammeter is less than the first preset value, can determine that the carrier communication channel of the first ammeter breaks down, when the serial ports test success rate of the first ammeter is less than the second preset value, can determine that the serial communication channel of the first ammeter breaks down.

It should be noted that, the fault detection method that the embodiment of the present invention provides, when detecting the communication channel of the first ammeter, one can be selected detect the carrier communication channel of the first ammeter and serial communication channel respectively, also can detect the carrier communication channel of the first ammeter and serial communication channel simultaneously.

The detection method of a kind of power information acquisition system fault that the embodiment of the present invention provides, be applied to the checkout gear of power information acquisition system fault, comprise: the concentrator in checkout gear acquisition power information acquisition system is to the copy reading result of the first ammeter copy reading, and copy reading result is for representing whether copy reading is successful; If copy reading result represents copy reading failure, then checkout gear detects the communication channel between concentrator and the first ammeter, obtains the testing result of communication channel, and testing result is for representing whether communication channel exists fault; Checkout gear, according to testing result, determines that communication channel exists fault or the first ammeter exists fault.
