The invention relates to a software detection method and a software detector and a software detection system using the method. The software detection method is used for detecting program flow information of utility software in operation in real time, model detection is used for judging whether a specific structure or a leak exists or not after code instrumentation of software to be detected, code execution tracks are found out, and then the program flow information is sent to a supervision node or a supervision network in a wireless or wired mode. The method can conduct real-time monitoring on the software operated inside a computer system in the legal supervision field. The software detection system forms a legal metering monitoring network to monitor use of metering tools, provides service and support for fast reaction of law enforcement and cracking of fake products. The method can detect specific objectives of back door programs, cheating commands and the like in electronic weighing instrument software or financial regulation software, and enables detected information to be transmitted to outside to enable a supervision authority to conduct real-time monitoring.

The invention relates to a device for controlling the power supply of a mobile communication base station, which solves the problem of electric power resource waste caused by long idle state time of the mobile communication base stations along a high-speed railway. The device for controlling the power supply comprises a base station power source input end used for connecting a power supply sourceof the mobile communication base station, a base station power source output end used for connecting electricity consuming equipment of the mobile communication base station, a power switch connectedbetween the base station power source input end and the base station power source output end, and a segmented time controller used for controlling the power switch to be switched on at a preset time when the base station is started to run or controlling the power switch to be switched off at the preset time when the running of the base station is stopped according to base station time-segmented power supply setting information. The invention also provides a method for controlling the power supply of the mobile communication base station, which further widens the application range of a solar photovoltaic power generation system in the mobile base station.

The invention relates to a software detecting method as well as a software detector and a software detecting system applying the method. The software detecting method is used for the real-time detection of the procedure information of a running program of application software. After the operation of code instrumentation is carried out on software to be detected, the condition whether a 'special structure' or a 'flaw' exists or not is judged by model detection, a code execution track is also found out, and then the procedure information of a program is transmitted to a supervising node or a supervising network by adopting a wireless or wired mode. The software detecting method can be used for carrying out real-time monitoring on running software inside a computer system in the field of jural supervision. A jural metering and monitoring network is formed by the software detecting system disclosed by the invention and is used for monitoring the use of a metering appliance so as to provide service and support to the quick response of enforcing the law and cracking down on counterfeit goods. The software detecting method can be used for detecting specific targets, such as a 'backdoor program', a 'cheating password' and the like in electronic weighter software or financial supervision software and also used for transmitting information obtained by detection to the outside so as to be monitored at real time by the department of supervision.

The invention discloses an auxiliary oil-sealing method and device for a combustion gas turbine, and belongs to the field of combustion gas turbine designing. The oil-sealing method comprises the steps as follows: a first stop valve is arranged on an oil supplying pipe; a high-level oil tank is arranged, one end of the high-level oil tank is connected onto the oil supplying pipe through an oil charging pipe, the joint of the high-level oil tank and the oil supplying pipe is located between the first stop valve and the combustion gas turbine, and the other end of the high-level oil tank is connected with a fuel tank through an oil returning pipe; and a second stop valve is arranged on the oil charging pipe. According to the auxiliary oil-sealing method and device for the combustion gas turbine, the high-level oil tank is arranged at the highest point of the whole device; when the combustion gas turbine is started, both the first and the second stop valves are opened, and fuel oil enters the high-level oil tank and the combustion gas turbine through the oil charging pipe; after the high-level oil tank is filled with the fuel oil, the extra fuel oil is discharged back to the fuel tank through the oil returning pipe; when the combustion gas turbine is stopped, the first stop valve is closed, the second stop valve is opened, the fuel oil in the high-level oil tank flows into the combustion gas turbine for oil-sealing by means of the liquid level difference through the oil charging pipe, and thus the parking time of the combustion gas turbine is remarkably prolonged.

The invention provides a wind damage proof billboard frame; the billboard plate is arranged on the upper end of an upright post; the billboard plate is composed by covering and fixing the advertising screen panels on the frame; the billboard plate and the upright post are made in bi-direction relative rotation connection structure along the shaft and having circular rotor and circular seat; the rotor and the seat are mated into circular body and sleeved on the upper end of the upright post; the circular rotor is fixedly connected with the billboard frame; the circular seat is fixed with the upper end of the upright post. The design refers to the wind vane structure, when the wind power of the billboard plate is more than the weight of the billboard plate, the billboard plate will rotate left or right along the upright post and raise to change the direction such that the side load wind automatically reduce the sail area; when the wind power of the billboard plate is less than the weightof the billboard plate, the billboard plate automatically turns around the upright post and descends to restore the showing direction. The diameter of the upright post can decrease, and the area of the billboard can increase; the invention has simple structure, reduced maintenance cost, and effectively solves the problem that the existed outdoor large billboard is easy to be destroyed by strong wind or typhoon.
