Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to a non-contact acquisition device for synchronous loop current. Background Art

[0002] In the train signaling system, the synchronous loop equipment ensures that the train can stop accurately at the platform; when the synchronous loop fails, the train cannot stop accurately, resulting in the doors and platform screen doors not being able to open in conjunction, requiring the driver to operate manually, affecting operating efficiency.

[0003] If a fault is not handled promptly, it will affect the operating efficiency of the entire line. Analysis shows that synchronous loop faults are generally caused by abnormal current flowing through the synchronous loop. Therefore, monitoring the current of the synchronous loop plays an important role in improving or even eliminating synchronous loop faults. Summary of the Invention

[0004] To achieve the above-mentioned purpose, the present invention proposes a non-contact acquisition device for synchronous loop current, comprising: two non-contact current sensors, a current sampling filter module, a communication module and a calculation module; wherein the two non-contact current sensors are both connected to the current sampling filter module, the current sampling filter module is connected and communicated with the calculation module, and the communication module is connected and communicated with the calculation module; wherein the two non-contact current sensors acquire the synchronous loop current and transmit it to the calculation module via the current sampling filter module; wherein the calculation module transmits the synchronous loop current to the data analysis cloud platform via the communication module. It is used to replace manual measurement and recording of synchronous loop current, overcome measurement or recording errors caused by human factors, capture instantaneous current fluctuations, detect the insulation condition of the loop cable, communicate with external platforms, and upload sampling results to the external platform according to rules, so as to facilitate other applications to call early warnings.

[0010] DETAILED DESCRIPTION

[0011] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0012] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0013] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0014] Currently, maintenance personnel perform periodic visual inspections of synchronous loop lines. Because traditional current measurement methods require circuit dismantling, loop line current is rarely recorded during maintenance, making it difficult to identify current trends. Loop line current cannot be determined until a fault occurs, hindering the timeliness of troubleshooting.

[0015] Synchronous loop equipment is deployed at every station along the line, and regular visual inspections of the loop require considerable human resources.

[0016] Therefore, if Figure 1 As shown, a more effective synchronous loop current non-contact acquisition device is proposed, including:

[0017] Two non-contact current sensors 101, a current sampling and filtering module 102, a communication module 103 and a calculation module 104;

[0018] Wherein, the two non-contact current sensors 101 are both connected to the current sampling and filtering module 102, the current sampling and filtering module 102 is connected and communicated with the calculation module 104, and the communication module 103 is connected and communicated with the calculation module 104;

[0019] The two non-contact current sensors 101 collect the synchronous loop current and transmit it to the calculation module 104 via the current sampling and filtering module 102;

[0020] The calculation module 104 transmits the synchronous loop current to the data analysis cloud platform via the communication module 103 .

[0021] In one embodiment, the communication module 103 further includes: a communication controller, which transmits the synchronous loop current to a data analysis cloud platform via an RS232 protocol.

[0022] In one embodiment, the acquisition device further includes: a power supply module 105 for supplying power to the two non-contact current sensors 101 , the current sampling and filtering module 102 , the communication module 103 and the calculation module 104 through an external power supply.

[0023] In one embodiment, the computing module 104 further includes: an STM chip and a 512KB memory chip; wherein the memory chip stores sampling control and data processing compensation programs.

[0024] Specifically, a non-contact current collection method can be used to collect the synchronous loop current according to a certain period; the collected current is processed by the module and transmitted to the external platform through the RS232 protocol, and the external platform saves and analyzes the results.
