Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
In order to solve the Electrical Safety problem forgotten closing device power supply because staff leaves operation field (comprising next) for a long time and cause, as shown in Figure 1, the invention provides the unloaded safety power-off device of a kind of equipment, it is characterized in that, comprise: shell, central processing unit, input interface, output interface, display unit, power supply unit, described central processing unit is connected with described output interface with described input interface, described input interface is connected with the main operation contactor of equipment, described output interface is connected with device power supply (DPS) switch, described display unit is connected with described central processing unit, described power supply unit is connected with device power supply (DPS) switch, described shell holds described central processing unit for installing, input interface, output interface, display unit, power supply unit.
Wherein, described crust of the device material is ABS engineering plastics, constituent apparatus main body, for installing all the other each building blocks of storing apparatus, degree of protection IP20.
Wherein, described display unit is made up of operational module and display module, and operational module, for setting outage detection interval time, can 0 to be arranged to 24h scope according to demand.Display module can adopt charactron letter to join the time value of display setting (can only), and LED display also can be adopted as high end configuration (additionally can show operate time and the number of times of tape deck).
Wherein, described input/output interface is used for receiving equipment airborne signals and power-off signal, is the transition element that CPU element is connected with external signal, does not possess control and changes the function of signal type, can adopt crimp type terminal form or connector form.
Described CPU can adopt single-chip microcomputer to form as main body, it is the brain of breaker device of the present invention, by programming accordingly to single-chip microcomputer, can realize detecting equipment airborne signals and stimulus, timing and time-controlled function (timer function), for control appliance power-off.CPU element is similar to Timer Controlling principle, when the main operation contactor of equipment disconnects, be connected to the chain disconnection of normally opened contact on this device, after CPU element detects everything break signal, timer internal starts timing, when after the operate time that timing reaches setting, CPU element sends driving instruction makes circuit breaker tripping coil electricity produce magnetic, drives circuit breaker automatic trip, finally realize unloaded safe power down function by magnetic force.
In addition, described breaker device also comprises manual test module, described input interface and described manual test model calling.Device panel is provided with described manual test module, manual test module manually the triggering signal of button and equipment to exceed the signal at setting-up time interval idle time suitable, for detecting real-time and the validity of breaker device action of the present invention.
The unloaded safety power-off device of described equipment adopts AC220V working power, and the lower end of device power supply (DPS) switch is taken from power supply, and after device powers down, this device power supply is also cut off.
As shown in Figure 2, be the unloaded safety power-off device control flow chart of a kind of equipment of the present invention.The invention provides the unloaded safety power-off device control method of a kind of equipment, comprise the steps:
S1: central processing unit obtains equipment main operation contactor airborne signals;
S2: carry out timing to airborne signals, obtains airborne signals duration t
1;
S3: judge airborne signals duration t
1whether be more than or equal to power-off time interval of delta t, if airborne signals duration t
1>=power-off time interval of delta t, then perform step S4, otherwise, reset timing signal.
S4: control appliance mains switch automatic trip power-off.
Before the unloaded safety power-off device of equipment comes into operation, CPU element weaves control program, can realize timing, time control function, manually sets the power-off time interval of this device, such as 30min.In FIG, be arranged on by unloaded for equipment safety power-off device between device power supply (DPS) switch (low-voltage circuit breaker of the de-mouth coil of band) and the main operation contactor of equipment, airborne signals can be extracted from one group of normally opened contact of main operation contactor.When equipment downtime but main power source not yet cuts out time, the main operation contactor of equipment disconnects and by this signal feedback to the unloaded safety power-off device of equipment.This device CPU element carries out detection timing, timing controlled to airborne signals.If equipment just middle short time interval is shut down, such as, in 10min, operating personnel have carried out operation to equipment again, then reset timing signal.If for a long time (as reach setting-up time 30min, time length can free setting) operating personnel have not carried out associative operation to equipment again, then and this device CPU is that operating personnel have left working site (pattern of coming off duty) and forget that the situation of closing device main power source there occurs with regard to acquiescence.In this case, CPU sends the tripping coil power supply on a control command connection equipment main switch, and tripping coil obtains electric generation magnetic and drives device power supply (DPS) switch automatic trip power-off, plays safety protection function.
Further, test signal, for detecting the validity of this device, is sent by the manual test module that device is installed, and the button pressing manual test module can simulation no-load signal thus the real-time of checkout gear action and validity.Display unit has number of times and the time of display unit action, arranges the function of this device de-energizing actions time.
When this application of installation is on numerical control device, a master control contact can be extracted drive the outside auxiliary relay connected in numerical control device PLC control program, and then obtain airborne signals from this auxiliary relay.
The invention provides the unloaded safety power-off device of a kind of equipment, have volume little, safe and reliable, device body can be arranged in the electrical control cabinet of equipment self, does not need the feature of the occupying volume external space.When production operation personnel leave for a long time operation field and non-closing device power supply time, this device at the time interval (according to the actual requirements arrange) the automatic cutting equipment power supply afterwards of setting, not only can ensure equipment Electrical Safety but also has saved the energy.
Above-described specific embodiment; object of the present invention, technical scheme are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
