The invention relates to a mother's life sign and fetus united monitoring method and a system thereof so that a great many of expensive mother and fetus monitoring devices are no longer required to be purchased for hospitals. Personnel in hospitals only need to purchase a certain number of life sign monitoring devices based on actual needs. When a puerpera needs to be monitored in terms of mother parameters, the life sign monitoring device is pushed to the place for monitoring. A central station automatically transfers data of the life sign monitoring device to a window which corresponds to a fetus monitoring device according to an equipment number or an identity number of a patient, all functions of one mother and fetus monitoring device are achieved, and mother and fetus monitoring results can be combined for diagnosis so that the problems that investment of hospitals is wasted and data of a fetus monitoring device and a mother life sign monitoring device which are separated cannot be combined are resolved.

The invention relates to a detachable mobile platform and a mounting and demounting method thereof. The detachable mobile platform comprises a lifting ballasting system and an in-service functional system. The lifting ballasting system comprises lifting legs, lifting devices, ballast tanks, lifting beams and mechanical connection joints. The in-service functional system comprises a platform body, a basic disk type foundation and pile legs. The lifting ballasting system can be connected with or disconnected from the basic disk type foundation through the mechanical connection joints so that the lifting ballasting system can be connected with or disconnected from the in-service functional system. According to the detachable mobile platform, by separating and recycling the lifting ballasting system of the mobile platform, the problem of investment waste caused when the lifting ballasting system of the mobile platform is idle for a long term is solved; and the recycled lifting ballasting system can be used repeatedly, the lifting ballasting system can function for a long term, and accordingly the purpose of lowering the investment cost of the mobile platform is achieved.

The invention provides a method for determining the number of gas production wells in a gas storage taking into account the change in the production capacity of gas wells. The functional relationship between the regression average formation pressure and the reasonable daily gas production volume of gas production wells is obtained by fitting the intersection point of the gas well production capacity equation and the wellbore pipe flow equation. As well as the fitting function relationship between the average formation pressure and the cumulative gas production, determine the average formation pressure of the gas storage on the ith day, and then obtain the reasonable gas production of the gas well in the gas storage on the ith day. The peak gas volume and the reasonable gas production volume of the gas well on the ith day can be used to obtain the number of gas production wells N required for the ith day in the gas production stage of the gas storage. i , select the maximum number of gas production wells required per day in the gas production stage of the gas storage as the number of gas production wells J required for the construction of the gas storage. Compared with the prior art, the invention determines the number of gas production wells in the gas storage by considering the gas production capacity change of the gas wells, which is more suitable for the actual situation on site, the calculation is more accurate, and the investment waste is avoided.
