The application discloses an underground space unmanned sensing and detecting system and method, wherein an unmanned detecting carrier platform acquires underground space surface layer data through a sensing radar holder and a unmanned aerial vehicle; then, the detecting target area is determined and the driving path is planned according to the acquired data; meanwhile, the unmanned detecting carrier platform places self-organizing network relay nodes at different positions through a mechanical arm and in combination with signal strength, so that a self-organizing network is finally formed, and the communication between the unmanned detecting carrier platform and the unmanned aerial vehicle in the underground space is ensured to be normal; when the unmanned detecting carrier platform drives to the target area, a seismic observation system is formed through the laid node type detector, and an active seismic source and a transient electromagnetic detecting device are started respectively, so that the seismic wave data and the transient electromagnetic data of the target area are acquired; the application can realize the sensing modeling of the underground space in an unmanned mode, and can also accurately acquire the detecting data of the whole underground space, thereby being convenient for the subsequent analysis and processing of the underground space data.

The application relates to a data and clock phase difference correction method, which comprises the following steps: a receiver performs secondary synchronization on an IO signal based on a CLK signal to obtain an IO synchronization signal; a starting bit falling edge pulse signal is obtained according to the IO synchronization signal, and then a starting bit enable signal is set; the delay duration of the receiver and the IO signal is obtained; when a check bit error of a character frame received by the receiver occurs, a compensation time is determined, the data line is taken over at the compensation time according to the delay duration, the data line is driven to a low level, and the character frame is retransmitted by a transmitter. The receiver of the application can better receive the starting bit on the data line, has smaller timing requirements for the other party of communication, and can communicate with more products. The application avoids possible misjudgment and bidirectional driving of the transmitter, enables the communication between the two parties to be stably carried out, improves the performance of the interface, and enhances the compatibility. The application also relates to a receiver, a chip and a device.

This invention discloses a hardware module configuration method based on the ECN bus, comprising the following steps: scanning all hardware modules in the current hardware configuration using hardware configuration software, parsing and configuring all hardware modules to obtain configuration information; mapping the configuration information to the CPU memory address of the PLC module to establish communication with all the hardware modules; and downloading the programming software's executable program based on the configuration information to realize the configuration of the PLC system based on trusted hardware module information. This method, based on the hierarchical and loosely coupled management of PLC programming software, embedded software, communication bus, and hardware modules, achieves a single definition of hardware modules that is universally applicable throughout the system, reducing the workload of engineering configuration and effectively improving work efficiency and accuracy.
