Problems solved by technology

It directly takes out the voltage and current information from the network for recording, thereby abandoning the traditional sensor-based control method, solving the problem of more equipment required, more wiring, complex energy measurement system, increased system cost and reliability. Lowering, operation, maintenance and overhaul work is also relatively cumbersome and other issues

Embodiment Construction

[0036] Specific examples of the present invention are attached figure 1 As shown in the system structure diagram, the hardware composition of the MVB interface locomotive energy consumption recorder includes a main controller module 3, an MVB protocol control module 2, an MVB signal interface unit 1, a data display control unit 4 and a power supply unit 5. Hardware implementations such as figure 2 As shown, the system includes two MVB signal interface units 1, which can ensure the reliability and stability of MVB signal transmission. Each MVB signal interface unit 1 collects the differential signal from the MVB network through pins 6 and 7 of the MAX3088, converts it into a Manchester coded signal recognizable by the MVB protocol control module 2, and connects it to the MVB protocol control module through an optocoupler 2. The MVB protocol control module 2 and the main controller module 3 exchange data through interconnected data lines, address lines and control lines, and ...

Abstract

The invention discloses an energy consumption recording instrument used for an MVB interface type locomotive, and a method for controlling the energy consumption recording instrument. The energy consumption recording instrument is based on a TCN-MVB network system and comprises a main controller module, an MVB protocol control unit, an MVB signal interface unit, a data display control unit and a power supply unit. The method comprises the following steps: an MVB signal is received by the MVB signal interface unit; and the signal, after being stored and converted by the MVB protocol control module and the main controller module, is transmitted to the data display control unit, so that the instrument serves the function of recording and displaying energy consumption.

Description

technical field [0001] The present invention relates to locomotive network applications. Background technique [0002] The existing method for measuring and recording the energy consumption of locomotives is based on the traditional control method, receiving the voltage and current values ​​of the equipment through voltage and current sensors, and then sending these values ​​to the driver's cabin through a hard-wired direct connection, and Connected to a meter to display or record energy consumption. Since this method needs to connect each device separately, the more devices, the greater the amount of wiring required, so the energy measurement system to be built is complicated, which increases the cost of the system, reduces the reliability, and the operation, maintenance and repair work is relatively cumbersome. Nowadays, many locomotives are networked in control, and the voltage and current information that needs to be measured to record energy consumption is also transm...
