Embodiment 1

[0046] see figure 1 , figure 1 This is a schematic structural diagram of a steel plate length measuring device provided in an embodiment of the present application. Depend on figure 1 It can be known that the steel plate length measuring device in this embodiment mainly includes: a speedometer, a photoelectric sensor, a processing module, a communication interface and a display. The tachometer is used to measure the running speed of the steel plate to be measured. The tachometer in this embodiment detects the running speed of the steel plate to be measured in real time, rather than measuring the transport speed of the roller table. This structure can avoid the traditional device. measurement, which is beneficial to improve the accuracy of measurement results.

[0047] In this embodiment, the photoelectric sensor is used to collect the arrival time and departure time of the steel plate to be tested. In this embodiment, the jump signal of the photoelectric sensor is used to c...

Embodiment 2

[0054] exist Figure 1-Figure 3 On the basis of the embodiment shown, see Figure 4 , Figure 4 A schematic flowchart of a method for measuring the length of a steel plate provided in the embodiment of the present application. Depend on Figure 4 It can be seen that the method for measuring the length of the steel plate in this embodiment mainly includes the following processes:

[0055] S1: After the roller table starts to run normally, judge whether the photoelectric sensor jumps from the light-passing state to the light-shielding state.

[0056] In this embodiment, it is determined whether a steel plate arrives according to the jump signal of the photoelectric sensor, and whether to start the measurement. In the normal production process, when the steel plate to be tested walks through the roller table to the position of the tachometer and the photoelectric sensor, the head first reaches this position.

[0057] If the photoelectric sensor jumps from the light-transmitt...

Abstract

The invention discloses a steel plate length measuring device and method, the device comprises a speedometer, a photoelectric sensor, a processing module, a communication interface and a display, and the speedometer and the photoelectric sensor are installed in the middle position above a roller way in parallel. The method comprises the following steps: after a roller way is started, judging whether a photoelectric sensor jumps from a light-passing state to a shading state or not; if yes, detecting the head of the steel plate; recording the current moment and starting a speedometer to detect the running speed of the steel plate; transmitting the running speed of the steel plate to a processing module in real time; judging whether the photoelectric sensor jumps from the shading state to the light transmission state or not; if yes, detecting the tail of the steel plate; recording the current moment and stopping the speedometer; calculating the length of the steel plate by using a formula according to the obtained running speed and running time of the steel plate; displaying the steel plate length. According to the invention, the steel plate length measurement precision can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of steel rolling automation instruments, in particular to a steel plate length measuring device and method. Background technique [0002] In the field of steel rolling, the length of the steel plate is an important indicator of the quality of the steel plate, especially for the size-sensitive steel products such as wide and thick plates, the impact of the length of the steel plate on the quality of the steel is particularly obvious. Therefore, how to measure the length of the steel plate is an important technical problem. [0003] At present, the method of measuring the length of the steel plate is usually: using the roller table with an encoder to measure, and convert the length of the steel plate according to the number of encoder pulses and the circumference of the roller table. Specifically, when the steel plate passes through the measuring roller table, the roller table drives the encoder to ...
