Abstract
The invention discloses a speed alarm device belonging to the technical field of speed alarm. The speed alarm device comprises a central processing unit, a speed sensor, a display and an alarm, wherein the speed sensor, the display and the alarm are respectively electrically connected with the central processing unit. The speed alarm device has the beneficial effects that the structure is simple, when the rotating speed of a machine is higher than an upper limit value or lower than the lower limit value, the speed alarm device can alarm, so that the production safety is improved.
Description
Technical field
The present invention relates to a kind of speed warning device, belong to speed alarm technique field.
Background technology
On a lot of machines the speed alarm is installed all, but this speed alarm only is when speed surpasses upper limit speed, to send warning.There are a lot of machines that upper limit speed and lower limit speed are all had certain requirement, in different working conditions, adopt low speed or high speed; When speed is lower than lower limit; Explain that problem has appearred in certain position of machine, should in time overhaul it, otherwise very big to the infringement of machine itself; Sometimes can cause the injury to personnel accident, lack on the market at a high speed and the alarm that can both report to the police of low speed.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of speed warning device, when speed is higher or lower than setting value, will send warning to the staff, avoids the generation of accident.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of speed warning device, comprise central processing unit, speed pickup, display device and alarm, and speed pickup, display device and alarm are electrically connected with central processing unit respectively; Central processing unit adopts single-chip microcomputer.
The invention has the beneficial effects as follows: simple in structure,, machine rotational speed can report to the police when being higher than higher limit or being lower than lower limit, improve the security of producing.
Description of drawings
Fig. 1 is a theory diagram of the present invention
Embodiment
To combine accompanying drawing that the present invention is described further below.
As shown in Figure 1: the present invention includes central processing unit, speed pickup, display device and alarm, speed pickup, display device and alarm are electrically connected with central processing unit respectively; Central processing unit adopts single-chip microcomputer.
Display device is used for the current speed of display device; When transferring to central processing unit, the detected speed of speed pickup handles; If when the speed that detects was between the higher limit set on the machine and the lower limit, central processing unit was failure to actuate, machine normally moves; When the speed that detects was higher than higher limit or is lower than lower limit, central processing unit was passed to alarm with signal, and alarm sends alarm sound, showed to have fault, and the fault of reminding the staff to carry out machine is got rid of.
Claims (2)
1. a speed warning device is characterized in that comprising central processing unit, speed pickup, display device and alarm, and speed pickup, display device and alarm are electrically connected with central processing unit respectively.
2. a kind of speed warning device according to claim 1 is characterized in that described central processing unit adopts single-chip microcomputer.
