其工作方式是:振动传感器对被控物体进行振动检渊并发出振动引起的电压变化信号输出,当有振动发生时振动传感器产生感应电动势,经积分电路对感应电动势信号进行快速提升,又经放大器放大,产生高电平信号,振动信号越强高电平维持时间越长,完成振动力与脉冲宽度成正比关系的输出脉冲信号给微控制器EM78P153S。 The way it works is: a vibration sensor detecting vibration of the controlled object and issuing deep changes in the voltage output signal due to vibration, the vibration occurs when there is a vibration sensor generates an induced electromotive force, EMF signal for the rapid increase by the integrating circuit, and through an amplifier enlarged, the stronger the high level signal is generated, the vibration signal of high level is maintained longer time to complete the vibration force and the pulse width is proportional to the relationship between the output pulse signal to the microcontroller EM78P153S.

振动信号根据高电平维持时间的长短分别定义为1〜S级,由图9程序流程图可知, 当钥匙插入锁芯连续启闭4次,会使图6中的锁芯状态产生4次开闭状态,使微控制器EM78P153S的P6.1上获得连续4次高低电平,程序通过判断P6.1的状态进入相应的振动等级设定处理程序,完成对振动检测等级设定的功能。 The vibration signals are defined as the length of time of maintaining the high level 1~S flowchart of FIG. 9 seen from the program, when the key is inserted into the continuous opening and closing cylinder 4, the cylinder 6 causes the state of FIG. 4 apart generating the closed state, so that the microcontroller P6.1 EM78P153S obtained on 4 consecutive high and low, the routine proceeds to a corresponding vibration level set by the state determination process procedure P6.1 complete vibration detection level setting functions.

振动检渊等级的设定方法如下: The method of detecting vibration level set deep as follows:

用户插入钥匙连续启闭听到喇叭鸣笛后停止钥匙转动,进入振动等级设定,之后听到 Hear the user inserts the key stops the continuous rotation of the key opening and closing the horn whistle, into the vibration level is set, after hearing

一声短鸣,表示为一级等级,听到两声短鸣,表示为二级等级,依次类推,级与级间停止 One short beep, expressed as a grade, you hear two short beeps, expressed as two grades, and so on, between the stage to stage stop

81秒,周而复始。 81 seconds, again and again. 等级设定数越大,振动检渕灵敏度越髙,例如:你想设定等级为3,只 The larger the level number is set, the more the subject Kinji Fuchikami Gao vibration sensitivity, for example: You want to set a level of 3, only

要听到3声短鸣后,将钥匙启闭一次即完成。 To hear after 3 short beeps, the key to open and close once complete.

(2) 掉电信息不丢失存储器为EZPR0M存储器,用于存放密钥和本智能控制器相关钥匙的编号以及相关钥匙已使用次数的记录,直接由微控制器EM78WS3S对其进行数据的存取。 (2) power down the memory is not lost EZPR0M information memory for recording the number of keys stored and intelligent controller related to the present key and the associated number key has been used, the data is directly accessed by the microcontroller EM78WS3S thereof.

(3) 可更换钥匙人工操作按键电路用于将键盘状态变为电平信号连接至微控制器EM78P1S3S的2号引脚,由微控制器EM78P153S根据这一电平信号转入钥匙的增加与作废处理程序,进行钥匙的更新与作废。 (3) manual rekeying key circuit for the keyboard state becomes a level signal is connected to the microcontroller EM78P1S3S pin No. 2, into an increase of the key according to the level of the signal generated by the microcontroller and void EM78P153S processing program to update and obsolete keys.

可更换钥匙人工操作按键电路由电阻R4、开关SW1和微控制器EM78P153S构成, 将开关SW1的一端接地,另一端直接连到微控制器EM78P153S的P67,通过电阻R4连接到+5V电源实现上拉电阻的功能。 Rekeying key may be manually operated circuit of a resistor R4, a switch SW1 and a microcontroller EM78P153S configuration, one end of the switch SW1 is grounded, and the other end connected directly to the microcontroller EM78P153S P67, connected to the + 5V power supply is achieved by pulling the resistor R4 resistance function.

其工作方式是:微控制器在系统程序的执行过程中(参见图7),—旦检測到尚存的钥匙插入锁芯后,通过软件判断开关SW1的状态,当开关SW1被按下时会使P67变为低电平,程序一旦判断到P67为低电平时转入钥匙的增加与作废处理程序,该程序将产生一系列的提示音供用户正确操作。 The way it works is: the microcontroller during execution of the system program (see FIG. 7), - upon detection of the remaining key into the lock cylinder, the switch SW1 is determined by the state of the software, will when the switch SW1 is pressed P67 goes low so that, once the program is determined to P67 is low and the increase in void into the key processing routine, the program will produce a series of tone for the user to operate correctly. 因此当用户发现钥匙丢了,只要还有一把钥匙尚在,就只须购买新的钼匙,首先必须是将尚在的钥匙插入锁内,然后按住智能控制器盒表面的按钮, 喇叭才会发出2声短鸣和1声短鸣,否则将立刻引起报警及相关控制,只有当听到喇叭发出2声短鸣和1声短鸣后拔出钥匙,插入新钥匙,智能控制器才会自动向新购置的钥匙写入密钥和形成编号,喇叭发出短鸣表示认可,同时丢失的钥匙将自动作废。 So when users find key was lost, as long as there is still a key, you only need to buy a new Molybdenum spoon, must first be inserted into the key still in the lock, then press and hold the button intelligent controller box surface, only speaker emits 2 short beeps and 1 short beeps, otherwise it will cause alarm and associated control immediately, only when you hear the horn emits 2 short beeps and 1 short beeps remove the key, insert the new key, intelligent controller only automatically written to the newly acquired key to the key number and form, speakers emit short beeps to acknowledge, at the same time lost keys will be automatically canceled. 如果后来又找到了过去的钥匙,此钥匙便成为了不被本智能控制器所认可的新钥匙,以后可以按新钥匙处理的方法重新使用,用户不必再为钥匙的丢失而担心。 If later found the key to the past, this has become the key will not be recognized by this new intelligent controller key, you can later re-used by the new key treatment method, users no longer have to worry about lost keys.

钥匙的增加与作废处理程序的流程参见图8。 Referring to FIG increased flow processing program obsolete keys 8. 微控制器系统在系统程序的执行过程中, 通过判断可更换钥匙人工操作按键电路中开关SW1的状态,当开关SW1被按下时,使P67变为低电平,程序转入钥匙的增加与作废处理程序,微控制器EP78P153S的8号脚, 发出连续3次40mS高电平和80mS低电平信号,完成3声短鸣的提示,如此时不是尚存钥匙,微控制器EP78P153S的8号脚,发出髙电平即报警声,直到插入尚存钥匙则使徼控制器EP78P153S的8号脚发出连续1次40 mS高电平和80 mS低电平信号,完成1声短鸣的提示使用者拔出钥匙,插入其他尚存钥匙或新钥匙,目前本产品允许保留3把钥匙, 将三把钥匙的编号存入E2PEOM中,表明钥匙的增加与作废处理完成,丢失的钥匙自动取消。 Microcontroller system during the execution of the system program, can be determined by manual rekeying key circuit state of the switch SW1, when the switch SW1 is pressed, P67 goes low, the program proceeds to increase the key void handler, the microcontroller EP78P153S pin No. 8, issued three consecutive high 40mS 80mS and a low level signal, suggesting the completion of three short beeps, so when the keys are not remaining, microcontroller EP78P153S No. 8 feet , issued Gao i.e. level alarm sound until the key is inserted so that the remaining pin 8 go around the controller 1 times continuously emitted EP78P153S 40 mS and 80 mS high level low level signal, the user is prompted to complete a pull short beeps the key, insert the key or other surviving new keys, this product allowed to retain three key, the three key numbers into E2PEOM, indicating that the key to increase the void process is completed, the lost key is automatically canceled.
