Embodiment Construction

[0024] The following cross-references to the appended Figure 1-6 Describe in detail.

[0025] In some special cases such as underground mining, it is necessary to perform multi-point emergency stop (or "lockout") for certain working conditions. For most common cases, only two signal wires (such as blocking wire and common negative pole) are needed to complete the emergency stop circuit. However, for a large number of emergency stop nodes, that is, when there are many emergency stop nodes or many locking points, it is often necessary to query the position of the locking points after locking, which becomes a problem. In the prior art, when there are many emergency stop nodes or many locking points, it is impossible to query or accurately locate the positions of the locking points, and at the same time ensure reliable locking. The present disclosure is proposed to solve this problem.

Abstract

The present disclosure relates to a device and method for triggering and querying a latched bus. The lockout bus trigger and query device may include: a lockout query module, at least one lockout feedback module, and a query terminal, wherein the lockout query module, at least one lockout feedback module, and the query terminal are connected through a lockout line, a query line, and a common negative pole. By means of the above scheme, the blocking and query functions are completed, and the long-distance, multi-node blocking and query functions can be realized. A new scheme has been added for the emergency stop field, which saves the query cost and does not need to manually confirm the locking point. And the effectiveness of the blocking points along the line is ensured through the disconnection detection, which increases the reliability and safety of the blocking.

Description

technical field [0001] The present disclosure relates to the field of control, and more particularly relates to a device and method for triggering and inquiring about a locking bus. Background technique [0002] Usually in underground mining construction, due to the obstruction of underground communication signals, signals such as mobile phones and walkie-talkies cannot be used underground. Usually laying corded telephones or shouting devices along the roadway is especially important in occasions where effective communication is required, such as laying corded telephones or shouting devices along the line on the transportation surface and mining surface. In such occasions, the shouting and locking device along the line is essential. It provides the function of loudspeaker and intercom along the line and the emergency stop function of the equipment for the noisy environment such as the transportation line and the mining face, which effectively improves the safety of the minin...
