Attention friends in Shanghai
The cold wave is coming again
And this time "frozen in earnest"
presently
Cold tide and high wind double blue warning high hanging!
Shanghai Central Meteorological Observatory issued a blue warning signal for high winds at 12:35 on December 24, 2021: Affected by strong cold air, it is expected that there will be 6-7 northerly winds in the city in the next 24 hours, and gusts along the coastal areas along the river will be 7-8, please pay attention to precautions.
Shanghai Central Meteorological Observatory issued a cold wave blue warning signal at 11:00 on December 24: Affected by the strong cold air in the north, it is expected that the minimum temperature in the city will drop by more than 8 degrees in the next 48 hours, and the minimum temperature on the morning of the 27th and 28th can reach about minus 2 degrees, with thin ice, and the suburbs are minus 6 degrees to minus 4 degrees, and there is ice or severe freezing.
The "power" of the cold wave
It is expected that the impact on the city will begin in the afternoon
Three days
The 48-hour drop can reach 8 ~ 10 °C
Shanghai officially entered winter

This time it can really be taken out!
Shanghai or the first snow
The cold wave is about to strike, and these two days, the bus company has carried out a major inspection of all the bus vehicles in operation. Comprehensively checked the hidden dangers of engine, chassis brake and electrical equipment of all vehicles; overhauled the heaters, air conditioning lines, plumbing pipes and valves of operating vehicles to ensure that the on-board air conditioning system is operating normally, the whole vehicle is heated, and the "sick car" is eliminated on the road to ensure the safety of the public in winter.
At noon on the 24th, the reporter saw in the parking lot of Nanchen Road of the bus company that for each bus vehicle entering and leaving the scene, the staff implemented strict disinfection measures.
Next to a 937 bus, the staff is conducting a key inspection of the vehicle's coolant, tire pattern depth, etc. Taking coolant as an example, the box with coolant at the rear of each vehicle is marked with an interval scale, and the capacity of the coolant needs to be kept between high and low scales, while the temperature should be lower than -15 ° C. The staff will sample the coolant in the box to measure the temperature to ensure that the temperature meets the requirements.
The wear of the wheel, related to the driving brakes, steering, etc., the staff use professional measuring instruments to measure the wear of the wheel, the depth of the tire pattern also represents the degree of wear.
For new energy vehicles, the normal operation of the charging device is an important guarantee for safe operation, so all the super capacitor vehicles such as bus four companies 11 road have conducted a large-scale charging device physical examination.
At the bus terminal of Bus No. 11 in Laoximen, emergency repair personnel are inspecting and calibrating the two down-voltage charging bows at the station. Since the pressure sensors and temperature sensors used in the charging bow are precision components, small deviations may occur every once in a while. In extremely cold weather, the accuracy of the equipment is more demanding, so the accuracy adjustment needs to be made in advance.
In extreme weather, once the super capacitor car has an unexpected failure, the emergency repair team will get out of the car within 3 minutes after receiving the report, and rush to the scene within 15 minutes to deal with the fault in time. In addition, in order to cope with this cold wave, the No. 11 team inspected and disinfected the heating system of all vehicles. When leaving the car every day, the heat and air conditioning will be turned on a few minutes in advance and a certain ventilation state will be maintained during the driving period.
