Step two: parameter setting is carried out on the sensor module, the pressure plate module and the positioning buckle; the pressing plate is positioned on the protection measurement and control screen, and is large in quantity and concentrated, so that the structure of the protection measurement and control screen is exquisite, and miniaturization is realized. The conventional functional components of the intelligent pressing plate need to be compatible with the traditional pressing plate in the aspects of visual power failure, color distinguishing, operation and the like. Under this background, need in the electrical aspect, stop the relevance between intellectual detection system, the normal function, guarantee that the clamp plate function does not receive intellectual detection system part state influence, even it takes place to damage, also can not produce negative effects to the former, the location buckle overlaps on the cantilever type clamp plate, when the clamp plate withdraws from, because there is the rotatory angle of buckle restriction, the angle sets up to (45 ~ 135 °). The pressure plate does not touch the adjacent pressure plate.

4. The online substation pressure plate state monitoring method according to claim 2, wherein step SS3 specifically comprises:
step SS 31: installing sensor boards and LIN communication bottom boards inside the protection measurement and control screen cabinet of the transformer substation according to the specific number of the pressing boards, setting the address of each bottom board according to 2nArranged in a pattern, nmaxThe maximum is 4, and 16 rows of pressing plates are mounted on each protective measurement and control screen cabinet at most;
step SS 32: each LIN communication bottom plate is connected with 9 pressing plates at most, and the address of each pressing plate state sensor module is obtained by utilizing the matrix scanning principle;
step SS 33: and uploading and storing the states of at most 16 × 9 pressing plates in the protection and control screen cabinet.
5. The online substation pressure plate state monitoring method according to claim 2, wherein step SS4 specifically comprises: the action of the pressure plate state sensor module is triggered by the pressure plate module, the positioning buckle and the non-invasive sensor; the pressing plate state sensor module detects the switching state and the retreating state of the pressing plate and uploads data to the pressing plate state collector module through LIN single bus communication.
6. The online substation pressure plate state monitoring method according to claim 2, wherein step SS5 specifically comprises: the clamp plate state collector module acquires clamp plate sensor data, and comprises: and acquiring a frame data message through the LIN single bus, and analyzing the frame data message to resolve the current putting-in and putting-out states of each pressing plate.
7. The online substation pressure plate state monitoring method according to claim 2, wherein step SS5 specifically comprises: the comparison of the pressing plate state collector module with the typical values in the database comprises the following steps: the running state and the maintenance state.
8. The online substation pressure plate state monitoring method according to claim 2, wherein step SS5 specifically comprises: the judgement of clamp plate state collector module and suggestion include: and if the current state is matched with the typical value, the LED indicating lamp on the corresponding module prompts correct operation, otherwise, the LED indicating lamp is operated illegally to give an alarm.
