Such as the circuit theory schematic diagram that Fig. 4 to 8 is the utility model managing security tools and instruments inspection alarm set modules, knot It closes shown in Fig. 3 to 8, the concrete operating principle of the utility model managing security tools and instruments inspection alarm set is：

Wherein, central processing unit use microcontroller U1, level generator using button (key1, key2, key3 and Key4), level generator uses transistor drive circuit (Q1 to Q24), and luminescent device uses LED light (LED1 to LED24), shows Show device using 12864 type liquid crystal display U3, power supply module uses the power module of mother's USB mouth U2.

It is defeated using STC12C5A60S2 types single-chip minimum system, Independent keys circuit, 12864 type liquid crystal displays, mother's USB mouth The four module composition managing security tools and instruments inspection alarm sets of power module and LED drive circuit entered.Wherein 12864 type liquid Crystalline substance screen is using the serial communication for only needing 3 I/O mouthfuls.LED light uses 9013 type transistor drive circuits, by single-chip processor i/o mouth Output signal is as transistor base signal, by controlling the on and off of triode, controls the light on and off of LED, so as to fulfill Managing security tools and instruments inspection prompting function.Wherein show whether managing security tools and instruments answers the state of inspection with the variation of LED light.LED Lamp is bright to represent that state can be used normally in this group of managing security tools and instruments, and LED light flicker represents that this group of managing security tools and instruments closes on to expire and send The time is examined, LED light is gone out, and this group of managing security tools and instruments is out of date needs inspection for expression.By four buttons on circuit board, flexibly set Each group lamp be always on and scintillation time, each group lamp can individual resets.

It should be noted that censored time is set by staff.The Work tool represented according to each icon is sent Overhaul period.Each managing security tools and instruments has corresponding safety code, and having the Work tool of what classification of regulation, how long inspection is primary.Usually peace Inspection period of full Work tool is three months general, half a year or 1 year.

Further, four buttons are divided into " function " button, " selection ", " confirmation " button and " return " button.It can be real The function that existing indicator light resets, changes the LED status time, changing clock.

Realize that the operation that indicator light resets is：

1) " function " button is consecutively pressed, presses " confirmation " button in " reset state " option, screen " 01 " occurs to refer to Show that lamp is numbered；

2) " selection " button is consecutively pressed, presses " confirmation " button in Target indication lamp number-optional, indicator light is reset to Work(returns to initial interface.

Realize that the operation for changing the LED status time is：

1) " function " button is consecutively pressed, presses " confirmation " button in " modification state " option, screen " 01 " occurs to refer to Show that lamp is numbered；

2) " selection " button is consecutively pressed, presses " confirmation " button in Target indication lamp number-optional, screen occurs " often It is bright " it is the state for wanting modification；

3) " selection " button is consecutively pressed, presses " confirmation " button in the state options for wanting modification, " second " occurs in screen To want the chronomere of modification；

4) " selection " button is consecutively pressed, presses " confirmation " button in object time unit option, screen " 01 " occurs and is Want the time value of modification；

5) " selection " button is consecutively pressed, " confirmation " button, Target indication lamp status maintenance are pressed in object time value option Make work(into, return to initial interface.

2) " selection " button is consecutively pressed, " confirmation " button is pressed in the when meta position of target modification；

3) " selection " button is consecutively pressed, " confirmation " button is pressed after the completion of modification object time position, it is successfully modified, it returns to Step 2；

4) after modification all confirms, " return " button is pressed, returns to initial interface.

In addition, in the either step operated more than carrying out, press " return " button and can return to initial interface

Specifically, single-chip minimum system is other than including microcontroller, also with exclusion, switch and crystal oscillator etc..It presses Key switch one end connects single-chip processor i/o mouth, and one end connection ground, I/O mouthfuls are high level when button is not pressed, and press rear button I/ O mouthfuls are directly connected with ground, become low level, thus by detect the I/O mouthfuls whether become low level can detect button whether by by Under.Due to the mechanical structure of button, when pressing one-touch, inner contact might have mechanical shaking for several times, Performance in circuit is to press one-touch, the I/O mouthfuls of switchings that on-off for several times is actually had with ground.In order to The button detection inside this multiple trigger of shake is prevented, must increase to disappear in program and tremble processing, i.e., be examined in first time After measuring low level, carry out one section of appropriate delay and wait for (about 5ms-10ms), low level is believed if can also be detected after delay Number, then it is believed that button is pressed, carry out normal program processing.

The communication of 12864 type liquid crystal displays and microcontroller has serial, parallel two ways, and parallel work-flow is relatively simple and fast Speed, but more I/O mouthfuls of resource must be occupied.Since 24 groups of LED light of driving need 24 I/O mouthfuls, 4 buttons are also respectively necessary for 4 I/O mouthfuls, volume residual can not meet parallel mode, therefore using the serial communication for only needing 3 I/O mouthfuls.

Since single-chip processor i/o mouth output current ability is limited, excessive LED light can not be driven simultaneously, therefore using triode Driving, using I/O mouthfuls of output signals as transistor base signal, controls the on and off of triode, so as to control LED light Light on and off.

Preferably, using 0 timing of timer inside microcontroller, it is primary that timing 50ms enters interrupt routine, into 20 times Then the 1s times arrive, and refresh Hour Minute Second variate-value and refresh screen display.Using 1 timing of timer inside microcontroller, timing It is primary that 25ms enters interrupt routine, into 20 times then the 0.5s times arrive, refresh the time parameter of every group of LED light, and compare and be always on Duration, flicker duration judge that current time should be always on, flickers or extinguish.0 priority of timer is higher than timer 1, i.e., false Such as during the interruption of timer 1, timer 0 also generates interruption just, will preferentially enter 0 interrupt routine of timer, during processing Clock shows, and if during timer 0 interrupts, timer 1 generates interruption just, then continues 0 interrupt routine of timer, After just handle 1 interrupt routine of timer.Thus it can ensure that clock timing has degree of precision, although can be produced to LED light timing Raw certain error (during the interruption of timer 1, interrupts, interrupt routine processing time will become if inserting timer 0 It is long), but 1 parameter of timer can be adjusted, error is compensated as possible, reduces error as possible.

Included Chinese word library, can directly display Chinese character inside 12864 type liquid crystal displays.The sequential that communicates is referred to instruction catalogue 12864 type liquid crystal display databooks.Since serial mode response speed is slower, after each write command, data, it is necessary to have suitable Work as delay, otherwise the response of 12864 type liquid crystal displays do not come it is light then leads to loss of data, mess code, display error, it is heavy then flower is caused to shield, Collapse.
