Abstract

The invention relates to a signal relay station. The signal relay station comprises a data storage unit, a periodic signal detection unit, a data processing unit, a data transmission module and a periodic signal transmitting module, wherein the data storage unit is connected with the data processing unit and used for storing the data; the periodic signal detection unit is connected with the data processing unit and used for detecting a running period of an oil pumping unit in real time; the data transmission module is connected with the data processing unit and used for transmitting the data; the periodic signal transmitting module is connected with the data processing unit and used for transmitting a periodic signal of the oil pumping unit to an oil well indicator diagram well-opening-stopping monitoring device in real time; the data processing unit is a core control part and used for controlling the collection, storage, processing and transmission of the data. A public frequency band is used for periodically receiving the data of different collection devices on site and periodically transmitting the data to the relay station so as to prevent the mutual interference of the data in the transmission process, so that the data transmission accuracy is improved, and the production cost is reduced; by adopting a novel method for detecting the running period of the oil pumping unit, the precision for detecting the period of the oil pumping unit is improved, and the periodic signal is transmitted in real time.

Description

technical field [0001] The invention belongs to the technical field of oil exploitation data transmission, and relates to a relay station which adopts a public frequency band to receive data from field-installed equipment and transmits it at a short distance. Background technique [0002] At present, the electrical parameters of the pumping motor and the wellhead temperature and pressure data of the oil well are automatically collected by specific equipment in the oil field, and the data is transmitted long-distance through the DTU module. The following problems exist in this method: the time of uploading data by each equipment is irregular, and it is easy to Mutual interference causes data to fail to be uploaded or uploaded data is wrong; each device needs to be installed with a DTU module, which increases production costs. Contents of the invention [0003] To solve the above problems, the present invention provides a signal relay station. [0004] The scheme adopted in...
