Background

With the development of science and technology, automatic driving gradually enters the lives of people and is accepted by people. In order to ensure the accuracy and safety of automatic driving, road side sensing equipment for collecting road surface conditions and traffic conditions in real time is generally arranged on a road, road side calculation units (MECs) for analyzing and calculating road information in real time are arranged on two sides of the road, and road side communication units (RSUs) for communicating with an intelligent internet vehicle in real time are arranged on two sides of the road. The roadside sensing equipment mainly comprises a camera, a laser radar, a millimeter wave radar and other equipment, can collect road congestion conditions, animal disordering on the road, pedestrian walking, article dropping, traffic accidents and various violation phenomena in real time, and transmits the collected road information to a roadside computing unit (MEC). The method comprises the steps that a road side computing unit (MEC) analyzes and computes received road information, the computed result is transmitted to a road side communication unit (RSU), the road side communication unit (RSU) transmits the analyzed and computed result to a rear vehicle in real time, the condition of a road in front of the rear vehicle is informed in advance, the rear vehicle can conveniently acquire dangerous information in advance and avoid the dangerous information, and therefore accidents such as chain rear-end collision and the like caused by the fact that the condition of the road in front is not known are avoided.

However, in actual use, there are problems as follows:

1. because the MEC and the RSU are configured one to one, the RSU is arranged on a cross bar of the portal frame, the MEC is arranged on a vertical bar of the portal frame, the number of wiring points is large, the complexity is increased for on-site construction wiring, the number of fault points is large, and the reliability is reduced; meanwhile, the MEC has an own equipment box, the number of devices in the equipment box is large, the devices are discrete, and the failure cannot be sensed, so that when one device in the equipment box fails, the whole equipment is broken down;

3. as the lightning protection devices in the MEC and the RSU cannot be recovered after tripping, and the MEC and the RSU on the expressway are generally arranged at an interval of 500 meters, when the lightning protection devices in thunderstorm weather are trigram, a plurality of devices within the range of 200 plus 300 kilometers are damaged, the centralized maintenance in the next day is difficult, and the time and the labor are consumed;

4. the power failure protection is not provided, when power failure occurs, the MEC and the RSU equipment are damaged, the road condition cannot be continuously provided for the vehicle, and the safety factor is low;

5. in remote areas and on the side of expressways, such scenes that personnel on site are difficult to maintain, high in cost and lack of timeliness are required, and equipment has the remote management and maintenance capability. However, most of the current devices do not have the remote management capability, and even a few of the devices have the remote management capability, there is a higher threshold condition, for example, a network is necessary, the device system operating system and the system CPU also have to continue to work, the remote server can continue to perform data docking interaction with the device or send an operating command, and when the system crash CPU hangs down in extreme cases, for example, the device remote upgrade fails, the system CPU hangs down due to high-density interruption, the crash due to memory leakage, and the like, the remote maintenance means is also broken.

1) and (3) monitoring the system state: hardware indexes such as temperature/occupancy rate/memory/hard disk of CPU (Central processing Unit) are polled

If the exception occurs, entering an exception handling branch:

1.1) restarting CPU: triggering the restarting action of the CPU by a RESET signal of the CPU which is butted on a circuit;

1.2) restoring factory settings: the factory program of the CPU is re-burned through the REC burning function of the CPU which is connected with the circuit, so that the factory setting state is restored;

1.3) switching fiber channels: the CPU works at the optical fiber port (mentioned above optical port chip connected with the MEC core calculation module) at ordinary times, the MCU also has a standby optical fiber port (mentioned above optical port chip connected with the MCU), the two optical fiber ports select the electronic switch through a channel, and the MCU controls which path is gated. When the MCU detects that the CPU is in a downtime state, the CPU is restarted and still cannot be recovered to operate, the optical fiber channel of the MCU is actively switched, so that a remote platform of the system can be communicated with the MCU;

1.4) switching 4G channels: the main 4G channel (the above mentioned 4G connected with the MEC core computing module through the extension connector) defaults to a 4G signal of the CPU, and when the MCU detects that the CPU is abnormally operated, the MCU controls the channel selection electronic switch to select an auxiliary 4G channel (the above mentioned 4G connected with the MCU);

1.5) switching back to the main CPU channel after saving: when the CPU of the MEC is rescued and recovered, the MCU switches back the optical fiber and the 4G of the CPU;

1.6) storage System Log: the MCU can store the system log, intelligently calculates the state of each crash, and feeds back the state to the remote control platform through a large amount of data, so that the overall improved equipment can avoid the crash and the hang-up.

2) System power supply and temperature management: power on/power off/sleep/warm up/start fan/battery management

2.1) electrifying to sense the temperature, and heating to-20 ℃ at the low temperature of-40 ℃; generally, when the working temperature of each component is not lower than-20 ℃, namely lower than-20 ℃, part of the components (such as a CPU, a memory, a dual-system hard disk and a system battery) stop working, so that in order to ensure the normal working of each component, when the temperature value detected by the temperature sensor is lower than-20 ℃, the MCU sends a signal to the heating assembly, the heating assembly is started to heat, and the normal working of each component is ensured;

2.2) starting the fan at ultrahigh temperature and controlling the rotating speed; when the temperature detected by the temperature sensor reaches a preset high temperature value, the MCU sends a signal to a motor driving the fan to work, the fan is started to rotate, the heat in the shell is discharged outwards in time, and meanwhile, the rotating speed of the fan can be controlled, so that the conditions that devices are burnt due to overhigh temperature and the working performance is poor are avoided;

and 2.3) battery power sensing, temperature sensing and charging and discharging management.

In summary, by integrating calculation and communication, wiring points can be reduced, the failure rate is reduced, and the reliability of communication and calculation is ensured; the system has the power-off protection function, when the system is powered off, power can be supplied to equipment continuously, time is won for maintenance, and maintenance personnel can have enough time to maintain the power of the whole circuit conveniently; when the maintenance is not carried out, power can be supplied to the equipment, the normal work of the equipment is ensured, information is continuously sent to the vehicle, the safety maintenance guarantee is provided for the vehicle, and the system stability is improved by 500%; the remote management system has the remote management function, can ensure the normal operation of the remote management function, and solves the difficult problems which can not be solved by common remote maintenance, such as the hang-up of a system core chip, the breakdown of an operating system, the failure of upgrade and the like.
