Problems solved by technology

Therefore, when the machine is running at a low speed, sometimes it is difficult for the operator to find this problem, which will cause a problem in a certain part of the machine. When the machine is running at a high speed, the damage to the machine itself is greater, and sometimes it will cause casualties. , the market lacks an alarm device that can alarm at both high and low speeds

Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0011] Such as figure 1 As shown, an alarm device includes a sensor, a central processing unit, a two-color indicator device, a display device and an alarm. The sensor, the two-color indicator light device, the display device, the alarm and the central processing unit are electrically connected.

[0012] The sensors include speed sensors and human sensor devices. The setting of the speed sensor mainly detects the operating speed of the machine. The setting of the human body induction device is mainly for the operator to perform protective work when operating the machine equipment, and transmit the signal to the central processing unit.

[0013] The two-color indicator light device includes a group of red lights and a group of yellow lights, which are connected with the central processing unit.

[0014] The display device outputs a signal fed back by the central pr...

Abstract

The invention provides an alarm device which belongs to the technical field of speed alarm. The alarm device comprises the components of an alarm, a central processing unit, a double-color indicating lamp device, a display device and an alarm. The sensor, the double-color indicating lamp device, the display device and the alarm are electrically connected with the central processing unit. The alarm device is advantageous in that the alarm device has a simple structure; and when the rotating speed of a machine exceeds a preset upper limit value or reduces to lower than a preset lower limit value, the alarm device can perform alarming in time, thereby reminding a user and improving production safety.

Description

technical field [0001] The invention relates to an alarm device, in particular to an alarm device for prompting low-speed or high-speed operation of a machine, which belongs to the speed alarm device. Background technique [0002] Machines currently on the market are equipped with speed alarms, but this speed alarms only send an alarm when the speed exceeds the upper limit speed, and lack an alarm when the machine is running at a low speed. Most machines will encounter various situations during actual operation. Generally, there are certain requirements for the upper limit speed and lower limit speed of operation. Therefore, when the machine is running at a low speed, sometimes it is difficult for the operator to find this problem, which will cause a problem in a certain part of the machine. When the machine is running at a high speed, the damage to the machine itself is greater, and sometimes it will cause casualties. , lack on the market the warning device that can report...
