Recently, a truck driver was fined for being disconnected from the Beidou system, which eventually led to a tragic incident of life. It is understood that the direct cause of the incident was the disconnection of the Beidou vehicle locator. The reporter found that many media directly called this incident “Beidou dropped the line”, and confused the Beidou satellite system with the vehicle terminal using Beidou satellite positioning. The EETC editor feels it is necessary to clarify…
On April 5, a truck driver was fined 2,000 yuan at an over-limit station in Fengrun District, Tangshan City, Hebei Province due to the disconnection of the Beidou system. Suicide by internal medicine. Once the incident was announced, it attracted widespread attention and became a hot search.
It is understood that the direct cause of the incident was the disconnection of the Beidou vehicle locator.
On April 6, the official Weibo of the Information Office of the People’s Government of Fengrun District, Tangshan City, Hebei Province issued a notice.
Adopted by the 13th executive meeting of the Ministry of Transport on December 16, 2013, and implemented on July 1, 2014, Articles 37 and 38 of the “Measures for the Dynamic Supervision and Administration of Road Transport Vehicles” stipulate that road If a transport operator engages in business activities using a transport vehicle whose satellite positioning device fails and cannot be kept online, the road transport management agency at or above the county level shall order it to make corrections. Those who refuse to make corrections shall be fined 800 yuan.
In addition, those who damage the satellite positioning device, interfere maliciously, block the signal of the satellite positioning device, and forge, tamper, or delete the vehicle dynamic monitoring data shall be ordered to make corrections by the road transportation management agency at or above the county level, and a fine of more than 2,000 yuan and less than 5,000 yuan shall be imposed. fine.
Why install a locator?
“Sina Finance” called the official website of Beidou Aerospace Group, and the staff replied: “The Beidou locator is only a device for receiving downstream signals. It is like you use a mobile phone to receive signals. The mobile phone can only receive signals, but the source of the signal is the signal tower, Operators. If there is a sudden interruption of the network, you need to ask China Unicom, China Mobile, China Telecom, and mobile phone manufacturers do not know the problem.”
As early as 2012, the Ministry of Transport stipulated that vehicles with fixed parameters and purposes above 12 tons, such as freight vehicles and semi-trailer tractors, must be equipped with Beidou driving recorders. Weibo KOL and communication industry expert @Occam’s Razor also popularized the reasons why vehicles with fixed parameters and uses of more than 12 tons must be equipped with Beidou driving recorders, and analyzed the possibility of “Beidou disconnection”.
At present, in addition to large trucks, all other “two passengers and one danger” chartered vehicles that are engaged in tourism, passenger cars of three types or above, and special vehicles for transporting dangerous chemicals, fireworks and firecrackers, and civilian explosives must also be equipped with Beidou driving recorders. Vehicle types are further expanding, such as police cars, school buses, and government vehicles. As early as 2012, the Ministry of Transport made regulations on the mandatory installation of Beidou driving recorders, the number is GB-T19056-2012.
@Occam’s Razor first explained the difference between “navigator” and “Beidou driving recorder”:
After entering the destination, it will guide you in real time, which is called a navigator. The Beidou driving recorder is not a navigator but a “black box”. It contains a SIM card, which records various driving information of the vehicle in real time and reports it to the control center. It is the legal basis for judging traffic accidents and maintaining the legal and legitimate rights of drivers.
Many technology bloggers have dismantled the Beidou driving locator
It is understood that this recorder is usually mainly used to detect whether there is fatigue driving, and large trucks will be forced to install this device on the road. If fatigued driving is detected, a reminder will be given. Without it, there would be no prompt, and it would be difficult for the driver to find it dropped.
The possibility of Beidou and GPS satellites dropping at the same time is 0
When it comes to the probability of Beidou satellites being dropped, @Occam’s razor believes that the current Beidou driving recorders are Beidou + GPS dual-mode. The Beidou system has 53 satellites and the GPS system has 30 satellites. These are the two largest global positioning and navigation systems in the world, and the possibility of failure and disconnection at the same time is 0.
China BeiDou Navigation Satellite System (English name: BeiDou Navigation Satellite System, referred to as BDS) is China’s self-developed, open and compatible global satellite navigation system. It is also the third satellite navigation system after GPS and GLONASS. After the official completion and opening on July 31, 2020, it will provide open, free, high-quality navigation, positioning and timing services to the world. The public services provided by the Beidou system are oriented to the public, within reach, and used on demand. Just like water, electricity, and gas, they continuously flow to all walks of life and enter the lives of ordinary people. At present, more than 120 countries and regions around the world use the China Beidou system.
As for what the staff said, will the instability of the ground base station uploaded from the vehicle to the control center happen often? @Occam’s Razor believes that China has more than 7 million base stations, accounting for 70% of the world’s total, especially along roads and railways with enhanced signal, it is difficult to find a place where there is no signal for a long time. “It is true that the signal cannot be transmitted through tunnels and other special occasions. The system has a plan for this. How many minutes without a signal report will it be judged as dropped. Once it is judged to be dropped, the system will automatically call the driver to ask for verification of the situation. , Beidou driving recorder is relatively safe and reliable.”
The quality of the rear-mounted recording locator is uneven
In addition, although these recorders are often called Beidou positioning systems, they are not directly related to Beidou satellites. These recorders are not designed by Beidou satellites, but by third-party companies. According to data from the China Communications and Communication Information Center, there are currently 362 truck terminal manufacturers and thousands of operating service providers across the country.
According to a report from China Business News, in 2013, a group of commercial vehicle companies began to pre-install tachographs and distribute a chip card before the new cars rolled off the assembly line. After the car owner or the logistics company buys the vehicle, they need to activate the chip card, write the car owner or company information, and upload it to the data management platform of the transportation management department, so as to realize the interconnection between the vehicle driving information and the data monitoring platform. This kind of driving recorder is commonly known as “front-loading product” in the industry.
At the same time, there are still a number of vehicles on the market that were produced earlier than 2013, or vans that were produced after 2013 but did not have pre-installed tachographs. Vehicle owners usually purchase tachographs by themselves through Auto Parts City. It is installed in the car in the way of hanging, which is commonly known as “rear-loading” products.
The functions of the front-mounted and rear-mounted products are roughly the same. Most of them have built-in Beidou satellite navigation and GPS navigation systems. The SIM chip card establishes a data connection with the traffic management department to provide driving information such as vehicle speed, driving time, and motion trajectory.
A person who once worked in the tachograph industry said in an interview with China Business News, “The quality and reliability standards of after-installation products are usually much worse than those of the front-mounted products. This is a general rule in the industry, no matter trucks or passenger cars. In some places It is indeed required to force the installation of ‘boxes’, but this may not be the needs of the fleet or the drivers themselves, so their attitude towards equipment procurement is that the cheaper the better. In this case, many suppliers compete for the needs, so they make the hardware cheap and make the hardware cheaper. The price war and after-sales service may not keep up. This has resulted in many boxes of average quality, and no one will actively deal with them after they fail.”
In an interview with Dabai News, truck rights protection expert Wang Jinwu believed that the cost of rear-mounted recorders on heavy trucks was about two or three hundred yuan, and the quality was uneven. In addition, it is difficult to cover all areas with telecom cards or China Unicom cards.
There are three common reasons for disconnection
Under normal circumstances, the vehicle-mounted terminal realizes positioning by receiving satellite signals, and then transmits the processed data to each provincial monitoring platform through the telecom operator’s network, and the provincial platform uploads it to the national freight big data platform. The signal status is shown on the device’s Display.
But like a mobile phone, the locator on the truck is sometimes offline, and the recorder shows no signal, that is, it is dropped. Wang Jinwu believes that this is a common situation, and summed up the three main reasons for Beidou’s disconnection: first, the quality of the recorder is poor, the second is the poor signal of the operator in the location, and the third is that the recorder does not work and has no signal because of man-made reasons. For example, two drivers each have one card, if they forget to change the card after changing shifts, or if the SIM card is in arrears, the device will be fined offline. Another possibility is that the driver deliberately damages and modifies the device to avoid monitoring.
A person engaged in satellite navigation and positioning also said that “Beidou dropped the line” itself is an imprecise statement. Regardless of whether there is equipment to receive, Beidou and GPS satellites will continue to send signals to the earth, so to be precise, it is the party concerned. Driver Jin’s tachograph was offline at the time of the incident.
So the problem of dropped calls is not the Beidou satellite, but other aspects such as third-party equipment, base station signals, or man-made.
Many of the locators installed on large trucks can also monitor abnormal behaviors such as fatigued driving, yawning, calling, smoking, and distraction, and give different levels of sound, light and shadow warnings to “remind” the driver in time. Correct their dangerous driving behavior and reduce the probability of traffic accidents. But for drivers, there will be a sense of restraint of being “surveilled”, and many drivers will “offline” the instrument because of this.
Xinhua News Agency commented: Beidou satellites should not take the blame
From a technical point of view, the equipment operator can monitor the online status of the terminal. When the equipment is offline, the operator can detect and notify the driver in real time, but the current policy does not mandate this. According to China News Weekly, the operator of the in-vehicle terminal device used by the driver disclosed that the driver’s device has been offline since December last year. The operator believes that the driver should have noticed the problem of the device being offline, but somehow did not deal with it.
Regardless of the final handling of the incident, the editor of EETC hopes that everyone can understand the difference between the concepts of Beidou satellites and vehicle-mounted terminals using Beidou satellite positioning from a correct perspective. Some imprecise expressions will mislead netizens. In order to avoid spreading rumors or even deliberately stigmatizing the Beidou system, it is necessary to clarify relevant issues.
Finally, a comment published by Xinhua News Agency is quoted:
