Embodiment Construction
[0024] The core of the present invention is to provide a locomotive control method under battery failure mode, which can identify whether the undervoltage signal is really caused by the low voltage of the battery module itself, so as to avoid misoperation; and the control method is simple and reliable , easy to operate and low cost.
[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Please refer to figure 1 , figure 1 It is a control flow diagram of a locomotive control method in battery failure mode in an embodiment of the present invention.
[0027] In one embodiment, as figure 1 As shown, a locomotive control method under a battery failure mode provided by the present invention includes the following steps:
[0028] S11: Determine whether the undervoltage ...

The invention discloses a locomotive control method under a storage battery fault mode. The locomotive control method under the storage battery fault mode is characterized by comprising the following steps: S11: judging that an undervoltage signal collected by an I / O (Input / Output) module of a locomotive is formed since the voltage of a storage battery module itself is lower than a first preset value or formed due to the fault of a monitoring module itself, wherein if the undervoltage signal collected by the I / O module of the locomotive is formed since the voltage of the storage battery module itself is lower than the first preset value, the step S12 is implemented; and if the undervoltage signal collected by the I / O module of the locomotive is formed due to the fault of the monitoring module itself, the step S13 is implemented; S12: controlling the locomotive not to run according to the undervoltage signal through a microcomputer control system of the locomotive; and S13: driving the locomotive to be in a running state through the microcomputer control system of the locomotive. With the adoption of such a method, whether the undervoltage signal is really caused by the condition that the voltage of the storage battery module itself is too low can be identified, so that the misoperation is prevented; and moreover, the control method is simple, reliable, easy to operate and low in cost.
Description
technical field [0001] The invention relates to a locomotive control method, in particular to a locomotive control method under battery fault mode. Background technique [0002] Overview of the existing technology: The battery charger of the existing Harmony 1 series electric locomotive mainly consists of 4 sets of AC / DC charging modules, 1 set of 24V power supply modules, and 1 set of monitoring modules. 4 sets of charging modules convert DC440V / 60HZ AC power to DC110V DC power. The monitoring module monitors the status of the AC / DC charging module, the status of the DC24V power supply, and the status of the DC110V power supply. If the monitoring module detects that the AC / DC module is faulty, the DC24V power supply module is faulty, the DC110V is lower than 77V, and the DC110V is lower than 88V, the monitoring module will send out AC / DC Module failure, DC24V power supply module failure, DC110V lower than 77V, DC110V lower than 88V, etc. The CCU detects these faults throu...
