This research applies the techniques of Radio Frequency Identification to construction management and techniques, as well as develops the RFID information system of construction management and the protection of workers' safety. The equipment of the RFID owns the distinction of exclusive tag and the distinction of cognoscible . Using it as the entrance guard system, it can make management more efficient and also control the site instantaneously. RFID communication has ad-hoc abilities, which can help transfer and store a great quantity of information. It can help spontaneously control the usages of piles of different materials, people's work in process, locations of the vehicles, and manage the construction safety in real time.

Since the signal equipments imported is unable to meet the development demand of urban rail transit, independent research of the domestic digital jointless track circuit is critical. Charateristic analysis for signal transmission of digital jointless track circuit was mainly studied in this thesis. Design digital jointless track circuit analysis software, which validated the transmission parameters could or not meet requirements of the normal, shunt and signaling states, was the key work of the research.

In the process of realizing the remote control of electromotor meter, it probes into the realization of the GPRS wireless collector emphatically which is on the kernel ground. It adopts the means of area-centralizing control to manage the electromotor meters affiliated by it. It communicates with the central control station by GPRS Modem and transmits the commands and data to the instrument by wireless, which makes the collection and transmission of the field data come true. In the process of realizing the remote control of voltage transformer meter, according to the actual requirement, it adopted the chips and modules that are different from the front means to design and realize the GPRS wireless communicating controller corresponding with the devices. It also introduces the mixed—mode Communication integrating the GSM with GPRS to settle the problem that too many GPRS terminals connecting with the central control station synchronously will affect the performance of the central control station.As a whole system, the central control station is the kernel of the digital oil field.
