Embodiment Construction

[0016] The detection and communication device for the temperature of the nodes in the underground coal mine high-explosive switch of the patent of the present invention is described below with reference to the accompanying drawings. Such as figure 1 As shown, the system is mainly composed of three modules: a wireless temperature sensor, a signal transponder and a temperature measurement host, and each device communicates with each other to complete the communication of information.

[0017] figure 2 Mainly for the temperature sensor part, the temperature acquisition process of the device is as follows:

[0018] 1) According to the on-site situation, the single-chip microcomputer adopts 3 timing working methods. In the debugging stage, the fast timing time is 2 seconds. When the time is up to 2 seconds, the single-chip microcomputer controls the level of the temperature sensing element to obtain the current temperature value; in the normal sending stage, the timing is 300 sec...

Abstract

The invention relates to a node temperature detection device applied to an underground coal mine high-explosive switch cabinet, which is mainly composed of three modules such as wireless temperature sensors, a signal repeater and a temperature measuring host, wherein each module reaches intrinsic safety authentication qualification, temperature variations of each node are monitored accurately in a high-explosive environment, and communication with an upper computer is performed timely. The wireless temperature sensors are responsible for real-time acquisition for the temperature of nodes inside a high-explosive switch and sending the temperature to the signal repeater in a wireless mode; the signal repeater is mainly responsible for receiving probe data, performing off-chip storage, receiving a command sent by the temperature measuring host at the same time, and giving a response and a reply; and the temperature measuring host is mainly responsible for querying data of the controlled signal repeater and the wireless temperature sensors within the specified time, performing display, early-warning and the like, and performing data communication with a surface workstation through the Ethernet at the same time.

Description

technical field [0001] The invention patent mainly relates to a temperature acquisition and transmission system in a high-explosive environment, specifically a detection and communication device for node temperature of high-explosive switchgear in underground coal mines. Background technique [0002] The operating environment of coal mines is characterized by the presence of flammable and explosive gases (such as CH4, CO, H2, etc.), coal dust and other potentially explosive risk factors. According to incomplete statistics, about 30% of coal mine gas and dust explosion accidents, more than 70% of underground fire accidents are caused by sparks from electrical equipment, overheating of mechanical equipment, or ignition of non-metallic materials. In order to prevent gas and coal dust explosion accidents, on the one hand, strict measures must be taken to monitor and control the concentration of underground gas and coal dust; Ignition sources and high-temperature heat sources of...
