(3) run calibration software in computer, the detection parameter of these ESAM modules of detection table address, authentication, tripping operation and combined floodgate is set in calibration software;
(4) after the full item of ready connection state's net encryption equipment afterwards passes through, then represent that ESAM module is safety, intact, again change next block ESAM module, repeat above test operation.
Advantage of the present invention is: compared with prior art, vibrational power flow of the present invention is reasonable, by adapter arrangement on special test ammeter, in ESAM Module-embedding adapter to be measured, detect, the integrity of ESAM module can be detected so in advance, the manual time and cost of labor that the ESAM module of the damage of having welded are dismantled and consume can be saved again.
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the enlarged diagram in I portion in Fig. 1.
Embodiment
See Fig. 1 and Fig. 2, a kind of ESAM module detecting device disclosed by the invention, comprise test ammeter 1 and adapter 2, described test ammeter 1 is provided with glove cavity 11, and adapter 2 installation by adhering is in glove cavity 11, adapter 2 is electrically connected with test ammeter 1, described adapter 2 is provided with ESAM module mounting groove 21, be plugged with ESAM module 3 to be measured in described ESAM module mounting groove 21, and this ESAM module 3 to be measured forms electrical connection after coordinating with ESAM module mounting groove 21 grafting of adapter 2; Described test ammeter 1 lower end is provided with 458 communication interfaces 12.
Convenient for making structure of the present invention install and remove, as preferably, adapter 2 described in the present embodiment is connected and fixed by screw 4 with test ammeter 1.
The ESAM module detection method of above-mentioned ESAM module detecting device, comprises the following steps:
(1) ESAM module to be measured is put into the ESAM module mounting groove of adapter, test ammeter is linked on existing ammeter platform, adds electric current and voltage;
(2) ammeter platform stage body is connected by existing 232 serial ports with existing computer, and test ammeter is connected with computer by 485 turn of 232 Serial Port Line by 485 communication interfaces of self;
