Disclosed are a monitoring system and platform for an electric airline food vehicle, which can realize the comprehensive monitoring of working and operating states of a new special transport vehicle, i.e. the electric airline food vehicle, and facilitate the organic integration of three levels of platforms, i.e. an airport, a vehicle operation enterprise and a vehicle production enterprise, to form an all-round airline food transport system monitoring platform. The monitoring system for the electric airline food vehicle and the three levels of platforms are mutually complementary and coordinate with each other to form a dynamic data interaction system for airport vehicles.

A vehicle control system and control method for an electric airline catering truck. The system comprises a CAN bus network, a charging control module, a driving control module, a brake control module, a power-on/power-off mode control module, a vehicle energy optimization management module, and a vehicle monitoring module. The system achieves reasonable control of the power system, increases mileage, and provides an energy-saving and efficient power output mode. Moreover, the system monitors driving safety and vehicle statuses in real time, and transmits instructions to various modules and components by means of internal calculation, thereby guaranteeing the safety performance of the vehicle, reducing hazards, and providing effective hazard prevention.

A method for controlling loading of an airport catering truck, comprising: when a power battery drives loading work, driven supporting legs to be supported only when the state of the whole truck satisfies the conditions of the normal working mode; the rising operation of a compartment is effective only when the state of the supporting legs satisfies the requirement for stably supporting the airport catering truck; a platform can be effectively operated to extend forwards only when the compartment reaches a rising end position; after the platform is operated by a worker to extend out, determine whether an obstacle affecting the extension of the platform exists or not, if yes, stop the platform extending out, and if not, drive the platform to extend out; when the worker operates the compartment to descend, first retract the platform; after the platform is retracted to the stop position, the worker is allowed to operate the compartment to descend; when the compartment effectively descends, the worker can effectively operate a refrigeration compartment to descend; after the compartment is descended to the descending stop position, the worker is allowed to effectively start supporting leg withdrawing. The safety operation of a loading system can be ensured by arranging a compartment ascending and descending condition, a supporting leg position condition, a platform stretching and retracting condition, and a truck start driving condition.

Abrégé

The present invention relates to an electric aviation catering vehicle upward loading driving method. There are three driving modes: 1. a normal working mode, wherein a high-voltage power battery drives an upward loading oil pump to work so as to control the entire upward loading work; 2. an electric emergency mode, wherein a low-voltage storage battery drives an electric emergency pump to work by means of a low voltage so as to control a platform to retract, a compartment body to lower and landing legs to withdraw; and 3. a manual operation mode, wherein the lowering of the body compartment and the withdrawing of the landing legs are performed manually. The object of the invention is to improve the reliability of an upward loading system. When the power battery fails, the low-voltage battery can be used to control the working of the compartment body. When the power battery and the low-voltage battery are unable to effectively control the working of the compartment body, the compartment body can be manually operated, thereby ensuring the safe operation of the upward loading system.

An electric aviation food vehicle, a loaded refrigeration system is provided with two power supply modes, namely a vehicle-mounted power supply and an external power supply. When the whole vehicle is in the charging state, the whole vehicle is powered off under a high voltage, and the air-conditioning compressor uses the external power supply to directly supply power to continuously maintain the constant temperature of a refrigeration compartment; when the vehicle is charged or the vehicle is in a running state, the vehicle-mounted power supply mode is used to ensure the temperature of the refrigeration compartment. The loaded system comprises a high-voltage action mode, a low-voltage action mode and a manual mode, and the whole vehicle adopts a three-way CAN channel to form a key communication network of the electric aviation food vehicle, and the whole vehicle is matched with different transmission rates, so as to make information interaction between gateways faster. An Internet of Things monitoring platform is composed of a three-level platform, including an airport full supervision platform, a vehicle operation enterprise platform and a vehicle production enterprise platform.

Abrégé

A temperature control method for a refrigerated container. The staff can adjust the target temperature of an air conditioner to within a first temperature range, and an air conditioner controller can also automatically adjust the temperature to within the first temperature range. If the staff or the air conditioner controller needs to modify the target temperature outside of the first temperature range of the air conditioner to within a second temperature range, the staff or the air conditioner sends information to a person in charge and/or a management platform, and modifies the target temperature of the air conditioner only after the person in charge and/or the management platform provides confirmation. The control method prevents the temperature of a lifting-device air conditioner from being adjusted to beyond the normal adjustment range, and prevents malicious operations or misoperations from causing the temperature of a refrigerated container to deviate from the target temperature. The invention also relates to an electric airline catering truck.
