Problems solved by technology

Since the working temperature of the hot pressing plate is not lower than 160°C, it is difficult for the control system circuit of the bipolar plate preparation hot press to work in this high temperature environment. At present, the PLC control system is difficult to realize the precise control of the bipolar plate preparation hot press
At present, production still mainly relies on experience, that is, workers constantly adjust process parameters according to site conditions, but the bipolar plates manufactured by this method not only have poor forming quality, but also have a long production cycle
Secondly, the hot press for preparing bipolar plates is a high-end and complex equipment, and its faults are relatively complex. At present, door-to-door maintenance lacks the working status data of the hot press for preparing bipolar plates, and its maintenance cycle is extremely long
However, the raw materials of bipolar plates, such as powder materials, are difficult to store. This maintenance method makes the production efficiency of the factory lower and the material utilization rate is low.

Embodiment 1

[0062] Such as figure 1 Part of the sensor layout of the wireless data acquisition module of the remote control and diagnostic system for the bipolar plate preparation hot press. 1 is an acceleration wireless sensor, 2 is an inclination wireless sensor, and 3 is a wireless infrared temperature sensor. Since the working temperature of the hot pressing plate of the bipolar plate preparation hot press is not lower than 160°C, it is difficult for the traditional circuit to work in this working environment. Therefore, wireless sensors are used to establish a wireless local area network to realize wireless monitoring. The remote communication module communicates with the command control module via Ethernet. The command control module has multiple network interfaces to realize data intercommunication between the wireless data acquisition module, the remote communication module and the command control module. The communication mode of each module of the present invention meets the ...

Embodiment 2

[0067] The bipolar plate preparation hot press is a complex large-scale equipment coupled with mechanical, electrical, and hydraulic systems, and its faults have obvious nonlinearity and coupling. Therefore, for the fault diagnosis of the bipolar plate preparation hot press, a reasonable fault monitoring should be established first. Point and establish a reasonable state range of monitoring point data for the working process of the bipolar plate preparation hot press. It is only the most basic function to judge whether the bipolar plate preparation hot press is faulty by analyzing the signals measured at the monitoring points. Due to the complexity of the bipolar plate preparation hot press, there are many monitoring points. According to the nonlinear relationship between the monitoring points, the specific cause of the failure of the bipolar plate preparation hot press can be found.

Abstract

The invention discloses a remote control and diagnosis system of a bipolar plate preparation hot press machine, and a remote control and diagnosis method of the bipolar plate preparation hot press machine. The system comprises a wireless data acquisition module, a command control module, a remote communication module and a remote communication platform. The wireless data acquisition module obtains three real-time parameters of the bipolar plate preparation hot press machine: a stamping speed, slide block flatness and temperature of a hot press board. The command control module makes a corresponding comparison of each real-time parameter with a corresponding working range and then makes corresponding judgments: when any real-time parameter exceeds the corresponding working range, power-off is executed on the bipolar plate preparation hot press machine, a fault state diagnosis is performed on state data of the bipolar plate preparation hot press machine, and a fault type of the bipolar plate preparation hot press machine is output so that maintenance is perform by a worker according to the fault type. A remote session between the remote communication platform and the command control module is achieved through the remote communication module, and remote expert consultation is performed on the real-time parameters, so a state of the bipolar plate preparation hot press machine is reanalyzed.

Description

technical field [0001] The present invention relates to the field of control and diagnosis of hot press for bipolar plate preparation, in particular to an automatic control system for realizing real-time action control and remote fault diagnosis of hot press for bipolar plate preparation. A remote control and diagnosis system and method for a plate preparation hot press. Background technique [0002] The bipolar plate stamping process has high requirements. During the bipolar plate processing process, the slider of the bipolar plate preparation hot press must be kept stable and flat, and the bipolar plate preparation hot press needs to be adjusted several times during the bipolar plate pressing process. punching speed. During the pressure holding process of the bipolar plate, it is necessary to keep the temperature of the hot pressing plate of the bipolar plate preparation hot press at a constant temperature, and the temperature difference of the hot pressing plate does not...
