The invention relates to signal detection and control equipment and a traffic signal failure automatic inspection system. The system comprises an upper computer and a plurality of signal detection and control equipment. The upper computer and the signal detection and control equipment are connected through a wireless communication network. The signal detection and control equipment comprise interface circuits, acquiring modules, signal conditioning modules, main controllers, wireless communicating modules and power management modules. The interface circuits are connected to traffic signal terminal equipment, the acquiring modules are connected to the interface circuits and are used for acquiring electrical parameters of the traffic signal terminal equipment, the signal conditioning modules are used for determining failures of the traffic signal terminal equipment by the fuzzy neural algorithm according to conditioned acquired signals, producing corresponding traffic signal failure alarming information when the failures of the traffic signal terminal equipment are determined, and transmitting to the upper computer through the wireless communicating modules. By the aid of the traffic signal failure automatic inspection system, intelligent remote management and maintenance of the traffic signal terminal equipment can be implemented.

Disclosed is a solar power generation device capable of automatically removing snow and dust. The solar power generation device capable of automatically removing snow and dust comprises a solar photovoltaic module, a base and a rotating unit mounted on the base. The rotating unit is provided with a motor and two vertical columns; a rotatable support shaft is arranged between the two vertical columns and fixedly provided with a sleeve perpendicular to the support shaft; a rotating shaft is arranged inside the sleeve and born by two bearings at the upper end and the lower end of the sleeve; the solar photovoltaic module is fixed at the upper end of the rotating shaft; a telescopic double-cross axle type universal coupler is connected between the lower end of the rotating shaft and the output shaft of the motor. The solar power generation device capable of automatically removing snow and dust can simulate the turning actions of living beings and eliminate snow and dust on a photovoltaic battery panel through centrifugal force generated by forward and reverse rotation of the photovoltaic battery panel, thereby obtaining high snow removing effects. Compared with vibration type dust removal, the solar power generation device capable of automatically removing snow and dust has small or even no influence on structural safety of the photovoltaic module, thereby avoiding damage to the photovoltaic module as much as possible. Compared with contact type dust removal, the solar power generation device capable of automatically removing snow and dust avoids the problem of abrasion on the surface of the photovoltaic battery panel.

The invention relates to an automatic base switching system and method for ETL operations. The method comprises the steps of scanning the executing situation of the ETL operations at regular intervals; piecing up manual intervention information according to operation information of an ETL operation reported with errors when the ETL operation reported with errors is found; checking the data synchronization situation of a backup base at regular intervals, judging the working state of the backup base, generating a base switching trigger instrument if the backup base is in the data synchronization completing state, switching an operated object of the ETL operation reported with errors to the backup base from a production base, base switching is completed, modifying operation configuration information according the manual intervention information, and the ETL operation is executed in the backup base. After the errors of the operation are reported, the operated object of the operation is switched from the production base to the backup base, and normal extraction of the operation is ensured so that the stability of data extraction can be ensured. The data timeliness of a downstream system is supported, manpower cost is saved, and the working efficiency is obviously increased, so that the system maintenance is more humanized and intelligentized.
