Description

Technical Field

[0001] The utility model belongs to the technical field related to subway maintenance equipment, and particularly relates to an intelligent power-off device for a subway electronic maintenance workbench. Background Technique

[0002] At present, there are many potential safety hazards in the power consumption scenarios of subway lines, and it is impossible to cut off the power when people leave, resulting in many power consumption safety accidents during the production process. Taking the common anti-static workbench in electronic maintenance as an example, the inability to cut off the power in time leads to the workbench running with electricity for a long time without anyone watching, posing a potential safety hazard in power consumption. At the same time, if some equipment such as soldering irons, desoldering pumps, hot air guns, etc. fail to cut off the power in time, it will not only cause the equipment to be damaged due to being kept at a high temperature for a long time, but also lead to some scalding accidents.

[0003] In response to such potential safety hazards, the hazards are mainly eliminated by establishing management systems. On the one hand, it is required that operators turn off the equipment in time after the operation is completed. On the other hand, full-time personnel are arranged to turn off the power supply of the workbench after the work is over. This mode not only increases the management cost but also cannot ensure that the equipment and the workbench are powered off in time, posing a great potential safety hazard. There is an urgent need for an intelligent device to achieve power-off when people leave and timed power-off for facilities and equipment. Content of the Utility Model

[0004] The purpose of the utility model is to provide an intelligent power-off device for a subway electronic maintenance workbench that can realize intelligent control of power on and off in power consumption scenarios, integrate multiple functions such as power-off when people leave, timed power-off, and remote power-off, and can provide real-time feedback on the operating state of the equipment.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the intelligent power-off device of the technical solution utilizes infrared sensing technology and Internet of Things technology, and realizes timely power-on when the operator approaches, and automatically cuts off the power supply of the equipment after the operator leaves, by means of human infrared detection and single-chip timing control. At the same time, it has the functions of timed power on and off, remote power on and off, and face recognition power on. The device can not only realize the intelligent and unmanned power management of the workbench, but also provide new intelligent solutions for various work scenes that require timely power off, greatly reducing the hidden dangers of electricity safety.

[0011] This device realizes unmanned management of power-on and power-off of facilities and equipment through intelligent solutions. It mainly uses the three functions of "power on when someone comes, power off when someone leaves", scheduled power on and off, and remote power off to avoid facilities and equipment from working with power on for a long time when unattended as much as possible, eliminating safety risks and greatly improving the working life of the equipment. At the same time, this device realizes unmanned and intelligent management of electricity safety, greatly reducing the workload of operators, avoiding the occurrence of safety accidents due to negligence of personnel, and realizing a significant reduction in management costs.

[0016] The communication module 6 adopts a wireless communication module, which is specifically set as a wifi network module to realize real-time connection and communication between the single-chip microcomputer and external devices.

[0017] The output control module 7 includes a transistor and a relay coil. The single-chip computer 2 drives the relay coil through the transistor, and controls the on and off of the live wire through the relay; the display module 9 uses an LCD display or an LED display; the control terminal 10 includes a smart phone, a tablet computer, a desktop computer, and an intelligent terminal device with a communication control function.

[0018] At present, the safety management of electricity use at workbenches is mainly carried out through the establishment of safety management rules and regulations. Staff members need to improve their safety awareness and cut off the power supply of equipment in time after the operation is completed. Full-time personnel need to be arranged to cut off the power supply of the workbench at the end of each day. The whole process requires personnel participation, which has high management costs and poor implementation effects. Equipment often works for a long time in an unattended state. Workbenches and various equipment are often unable to be powered off in time due to negligence of personnel. This will lead to a significant reduction in the life of facilities and equipment, and it is very easy to cause electricity safety accidents and personal safety accidents.

[0019] This technical solution is a device that can realize intelligent and unmanned power supply fault management of workbenches. In production and life, various facilities and equipment require staff to actively cut off the power before leaving and full-time staff to cut off the power on a scheduled basis, which is time-consuming and labor-intensive and can easily lead to power safety accidents due to negligence of personnel, reducing the working life of facilities and equipment. This device solves the problem that the power on and off management of power usage scenarios such as subway company workbenches is completely dependent on manual labor. It uses components such as single-chip microcomputers, induction recognition modules, display modules, and communication modules to realize main functions such as power off when people leave, scheduled power off, and remote power off, saving management costs and eliminating safety risks.

[0020] The infrared sensing module is used to collect infrared signals within a range of 1m. The signal is analyzed by the single-chip computer. When someone approaches within a range of 1m, the device is automatically powered off. When there is no one on duty for more than 30s, the power supply of the device is automatically cut off.

[0021] The wifi module is used to realize wireless network communication. ESP8266 is selected as the WiFi communication module so that the intelligent control device can communicate with the back-end mobile phone, computer and other terminals in real time. At the same time, time information is obtained through the wireless network, so as to realize the timed power-off function of automatic power-on during working hours and automatic power-off during off-duty hours. Through the terminal background, managers can monitor the working status of the equipment and remotely cut off the power supply of the equipment.

[0022] The single-chip microcomputer cannot directly control the 220V high voltage and high current of the live wire through the output port, so the transistor is used as a bridge to achieve "weak control of strong". The single-chip microcomputer uses the Nano-atmega328p module as the core control unit to drive the relay coil through the transistor, and the live wire is controlled by the relay, thereby realizing the switch control of the 220V strong electricity. The display module uses the NOKIA5110 display.

[0023] The intelligent power-off device realizes the intelligent and unmanned management of the power usage scenarios of maintenance equipment, and includes functions such as infrared signal detection, high-voltage relay drive, screen display, wireless network communication, system timing management, and remote equipment management. In conjunction with the corresponding external circuit, it can realize automatic power-on when people approach, automatic power-off when people leave, real-time indication of power-on status, and real-time network upload. At the same time, it can provide functions such as timed power-on and timed power-off of equipment and remote power-off by management personnel, realizing intelligent management of equipment power supply while greatly reducing the risk of power safety.

[0024] The above are only the preferred examples of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
