Abstract
The invention discloses a temperature warning system of a heavy truck, and belongs to the field of an automobile manufacturing technology. The system comprises a vehicle terminal, wherein the vehicle terminal is connected with a background management system through wireless communication; the vehicle terminal is connected with an information collector through a CAN (Controller Area Network) bus and a warning instrument, and the signal input end of the information collector is connected with the signal output ends of a plurality of temperature sensors arranged in a trunk bed; the temperature sensor is used for transmitting temperature signals detected in time to the information collector, the information collector is used for transmitting temperature signals transmitted to the warning instrument and the vehicle mounted terminal, the warning instrument is used for warning in accordance with a received temperature signal, and the vehicle terminal is used for transmitting the temperature signal to the background management system, and displaying a real time temperature value on the background management system, and controlling warning when the temperature value exceeds a preset limit value. According to the temperature warning system provided by the invention, the problem that goods are damaged because the internal temperature of a rear compartment of the heavy truck is unlikely to be controlled in the transportation process can be solved.
Description
Technical field
The present invention relates to field of automobile, especially a kind of temperature alarm system for heavy truck.
Background technology
Along with becoming increasingly abundant of expanding economy and industrial and agricultural products, strange land trade is more and more frequent, and in the process of freight transportation, some goods especially agricultural product are larger by the impact of temperature, too high or too low for temperaturely all can cause rotting of goods, cause any property loss.Heavy truck is the high capacity waggon of loading more than 14 tons, during its loading goods be stacked in pilothouse after trunk in, because goods is more and pile up closely, temperature variation in transportation in trunk is not easy to know and control, therefore be badly in need of a kind of heavy truck temperature alarm system, adopt an effective measure prevent cargo damage and avoid fire with the temperature variation grasped in time in trunk.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of heavy truck temperature alarm system of intelligence, and in the trunk that this system can solve heavy truck loading in transportation, temperature is not easily controlled, and causes cargo damage and causes the problem of fire.
In order to solve the problem, the technical solution adopted in the present invention is: this heavy truck temperature alarm system, includes car-mounted terminal, and described car-mounted terminal is connected by radio communication and background management system; Described car-mounted terminal is connected with information acquisition device with alarming instrument by CAN, and the signal input part of described information acquisition device is connected with the signal output part of multiple temperature sensor be arranged in heavy truck railway carriage; The temperature signal detected in real time is passed to described information acquisition device by wherein said temperature sensor, described information acquisition device will pass to described alarming instrument and described car-mounted terminal after this processes temperature signal, described alarming instrument makes warning according to the temperature signal received, this temperature signal is sent to background management system by described car-mounted terminal simultaneously, and on background management system, show real-time temperature value, control when this temperature value exceeds preset limit value to report to the police.
In technique scheme, technical scheme can also be more specifically: described alarming instrument comprises temperature indicator and hummer, and described alarming instrument is arranged on the panel board of described cab of heavy truck front end.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to adopting temperature sensor and information acquisition device to collect the element of process as temperature signal, temperature sensor effectively detects temperature in compartment and this temperature signal is passed to information acquisition device in time, be presented in real time on temperature indicator by the signal of information acquisition device process, temperature indicator display " temperature is too high " or " temperature is too low ", the hummer long time of alarm when real-time temperature values exceeds predetermined value.
2, because car-mounted terminal is connected by radio communication and background management system; The double protection with warning is with the warning preventing driver in vehicle transport process to ignore temperature because of tired.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Heavy truck temperature alarm system shown in Fig. 1, includes car-mounted terminal 2, and car-mounted terminal 2 is connected by radio communication and background management system 1; Car-mounted terminal 2 is connected with alarming instrument 3 with information acquisition device 4 by CAN, alarming instrument 3 is connected and composed by temperature indicator and hummer, alarming instrument 3 is arranged on the panel board of cab of heavy truck front end, and the signal input part of information acquisition device 4 is connected with the signal output part of 4 temperature sensors 5 be arranged in heavy truck railway carriage; The sensing element of temperature sensor 5 is thermistor, and wherein temperature sensor 5 exports different artifical resistance signals to information acquisition device 4 with temperature variation in compartment; After information acquisition device 4 is converted to temperature value according to resistance and vs. temperature, this temperature value signal is converted to digital signal transfers to alarming instrument 3 and car-mounted terminal 2; The temperature indicator of alarming instrument shows this temperature value, when this temperature value reaches preset limit value, temperature indicator display " temperature is too high " or " temperature is too low ", hummer long time of alarm; This temperature signal is sent to background management system 1 by car-mounted terminal 2 simultaneously, and shows real-time temperature value on background management system 1, controls to report to the police when this temperature value exceeds preset limit value.Native system can effectively detect temperature in compartment, and monitor in real time at background management system while temperature variation in real-time display compartment on vehicle-mounted temperature indicator, and exceed preset limit value alarm in temperature, avoid, because of damage goods too high or too low for temperature in compartment, causing any property loss.
