Parallel port data interception and GPRS wireless forwarding system

The invention relates to a parallel port data interception and GPRS (General Packet Radio Service) wireless forwarding system used in the field of road and bridge construction. The system comprises a parallel port data interception module and a GPRS wireless data sending module, wherein, the parallel port data interception module is connected with the GPRS wireless data sending module through an RS232 serial port; the parallel port data interception module comprises a data processing MCU circuit, a data latch circuit, a power supply circuit, a high-speed optical coupler circuit, a level drive circuit, a parallel port interface circuit, an RS232 electrical level transfer circuit and a reset and watch-dog circuit. The system provided by the invention can intercept the working real-time data of an objective system under the condition that the work of the objective system is not influenced, and forward the data to a computer of a handler through the GPRS wireless, so that the required data can be stored, counted
