The utility model relates to the technical field of fire fighting, and provides a pipe cable and a fire fighting truck, the pipe cable is used for water and electricity mixed transmission of a fire-fighting unmanned aerial vehicle, the pipe cable comprises an inner pipe, an outer pipe and a plurality of fixing assemblies, and the inner pipe is used for transmitting a fire extinguishing agent; the outer pipe sleeves the outer side of the inner pipe, and a cable penetrates through a space between the inner pipe and the outer pipe; the fixing assemblies are arranged at intervals in the length direction of the inner pipe, each fixing assembly comprises an inner fixing part and an outer fixing part, the inner fixing parts are arranged between the inner pipe and the outer pipe in a sleeving mode, the outer fixing parts are arranged on the outer side of the outer pipe in a sleeving mode, and the positions of the inner fixing parts correspond to the positions of the outer fixing parts; the inner fixing piece is suitable for abutting against the outer fixing piece so as to fix the cable and the outer pipe. The pipe cable provided by the embodiment of the utility model is used for overcoming the defects that the pipe cable is too heavy and low in flexibility, the inner pipe, the outer pipe and the cable are restrained by adopting the inner fixing piece and the outer fixing piece which are arranged at intervals, a steel wire layer does not need to be woven tediously, the overall weight of the pipe cable can be reduced, the flexibility of the pipe cable is improved, and later maintenance is facilitated.

This application relates to the field of microfluidic biosensing technology, and discloses a data acquisition and control system based on organ-on-a-chip microfluidics. The system includes a rhythm-locked loop module, a phase-controlled acquisition module, an impedance detection module, a data compensation module, and a closed-loop control module. The system generates a phase-locked clock by analyzing the pulse rhythm of the microfluidic pump drive current and chamber pressure timing data and aligning it with time-domain phase-locking. During the steady-state window of the laminar flow, it performs phase-controlled synchronous acquisition of the sensor array to obtain the raw biochemical dataset. During the low-level interval of the clock, it performs electrochemical impedance spectroscopy to obtain a fouling compensation factor. Based on this factor, it compensates and calibrates the data of each modality to obtain a biological phenotypic feature matrix, which is then input into a model predictive controller to achieve adaptive microfluidic closed-loop control. This application effectively improves the signal-to-noise ratio of data acquisition and the robustness of microenvironment control during long-term operation of organ-on-a-chip systems.

The invention discloses an enhanced vehicle-mounted accident emergency call device and system, and relates to the technical field of automotive electronics, the enhanced vehicle-mounted accident emergency call device applies a remote update and support function to an AECS, expands the application scene of the AECS, improves the safety performance of an intelligent networked automobile, the AECS is not a one-time delivery function any more, continuous maintenance and update can be achieved, and the service life of the AECS is prolonged. The actual usable life of the AECS is prolonged, and the actual usable region of the AECS is widened; the enhanced vehicle-mounted accident emergency call system supports remote updating and timely updating aiming at information changes of regions, laws and regulations and the like, the vehicle is not limited to be available in a certain region, a main engine plant does not need to design and develop a special part facing a vehicle exit, a vehicle owner carries out transnational self-driving travel, AECS can still be used, the maintenance cost is reduced, and the vehicle-mounted accident emergency call system is suitable for popularization and application. Therefore, the safety performance of the intelligent networked automobile is improved, and the driver experience is improved.
