Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] Such as figure 1 As shown, the vehicle GPS remote terminal data sending method provided by the present invention includes the following steps.

[0032] To judge the driving state of the vehicle, if the vehicle is in a stationary state, the GPS remote terminal will use the lowest frequency f min Send data; if the vehicle is in a fault state, the GPS remote terminal will use the highest frequency f max Send data; if the vehicle does not exceed the maximum s...

Abstract

The invention relates to a vehicle GPS remote terminal data sending method and a GPS remote terminal. The date sending method comprises the following steps of judging the running state of a vehicle, enabling the GPS remote terminal to send data in the lowest frequency if the vehicle is in a static state, enabling the GPS remote terminal to send data in the highest frequency if the vehicle is in a fault state, using a vehicle speed value as a measurement index to build a piecewise function with the vehicle speed as an independent variable which the vehicle in a normal running state without exceeding the maximum safe driving speed, choosing the lower frequency between the lowest frequency and the highest frequency when the vehicle speed is smaller, enabling the GPS terminal to send data in the lower frequency, choosing the higher frequency between the lowest frequency and the highest frequency when the vehicle speed is larger, and enabling the GPS remote terminal to send data in the higher frequency. By means of a piecewise variable frequency data sending method, the vehicle on different work conditions can be monitored. The vehicle GPS remote terminal data sending method has economical efficiency, flexibility and timeliness.

Description

technical field [0001] The invention relates to the field of engineering communication, in particular to a vehicle GPS remote terminal data sending method and the GPS remote terminal. Background technique [0002] Mobile cranes are widely used in various industries such as petrochemical, metallurgy, construction, wind power, etc. due to the flexibility of shifting the workplace. The users of cranes have changed from state-owned to individual users. Currently, individual users account for 80%. For the wide use of cranes, the company needs to track the condition of the sales vehicles, restore the fault parameters when a fault occurs, and grasp the vehicle information in time to serve customers better. The terminal sends vehicle parameter data (including the longitude and latitude of the vehicle, data collected by various sensors and buses, etc.) at a certain time. At the same time, customers also need to have certain monitoring of their vehicles. [0003] The contradiction t...
