In Fig. 1, a kind of automobile remote-control central controlled lock system comprises that telepilot is (on durability test console, remote controller buttons is resilient rubber parts, represent when pressing that signal sends, can not pass through the caoutchouc elasticity return on time, do not have signal to send in the return position), controller, dead lock and rat tail (in instruction carriage), elements such as solenoid valve, oil-water separator, air switch, auxiliary reclay, control chip are housed in the control box.Control box requires time control is carried out in the action of cylinder according to endurancing, respectively the unlock button and the locking button of telepilot are carried out actuation of keys by a unlock cylinder and a lock-up cylinder, unlocking signal that telepilot sends or locking signal are received by the controller in the car, controller is assigned release or locking instruction (controller and dead lock in the car are electrically connected by wire harness) to dead lock then, makes dead lock release or locking.Therefore can carry out endurancing to the motor central lock system by automobile remote-control central controlled lock system durability test control desk of the present invention, can examine the reliability of telepilot, controller, dead lock and whole motor central lock system.
Fig. 2 is an automobile remote-control central controlled lock durability test console schematic diagram, and its principle of work is:
In order to make principle of work of the present invention be convenient to describe, main control chip is elected the AT89S51 single-chip microcomputer as here, and input I/O mouth is selected P1.0, P1.1 mouth, also can select other I/O mouth, and they connect auxiliary reclay K1, K2 coil respectively, K1 wherein, and K2 is a normally opened contact.Control the commutation of unlock solenoid valve by the break-make of auxiliary reclay K1, control the commutation of lock-up solenoid valve by the break-make of auxiliary reclay K2, with unlock solenoid valve to the unlock cylinder control that commutates, with lock-up solenoid valve to the lock-up cylinder control that commutates, unlock cylinder is carried out actuation of keys to the unlock button of telepilot, and lock-up cylinder is carried out actuation of keys to the locking button of telepilot.This main control chip also is provided with two button S1, S2, and the wherein operation of S1 control single chip computer after the 220V alternating current is connected, is pressed the S1 entire equipment and just started working; S2 breaks down when equipment operation, after removing fault, press S2 after program will restart operation.
According to QC/T627-1999 " electric door lock for vehicle device " standard, release-locking-15 seconds requirement of a circulation of release, the timer internal T0 of available AT89S51 single-chip microcomputer controls P1.0, P1.1 mouth, and figure is shown in 3 for its control timing.P1.0 or P1.1 kept low level 1 second every 15 seconds, this moment K1 or K2 closure, realize corresponding button by the solenoid control cylinder, and P1.0 and P1.1 are to be 6 seconds in the low level time interval, this just in time satisfies QC/T627-1999 " electric door lock for vehicle device " standard to the requirement of cycling time of release-locking-release, display is responsible for showing the cumulative frequency of test, is example with 6 eight sections LED nixie displaies here, finishes the demonstration to the cumulative frequency of test.
The control program that is provided with in the single-chip microcomputer can have multiple, now lists two kinds:
Program one: the programmed control flow process as shown in Figure 4, concrete control procedure is as follows:
1, the control of the unlock button of telepilot
The unlock button of telepilot is by the break-make of the P1.0 control auxiliary reclay of AT89S51 single-chip microcomputer, thereby the actuation of keys of control unlock cylinder, the make-and-break time of P1.0 mouth is by the interrupt control of the timer internal T0 of AT89S51 single-chip microcomputer, make the unlock button work 1 second of telepilot, quit work 14 seconds.The specific implementation process is as follows:
Define a global variable num1 and be initialized as 0, (can interrupt realizing by repeatedly entering in fact being made as 1 second the break period of timer T0, here just in order to narrate conveniently), when entering the interruption of timer T0 at every turn, make num1 from adding 1, when num1 equals 15, again the num1 zero clearing.
In master routine, judge whether num1 is 0, if be 0, then the level of P1.0 is dragged down, judge again whether num1 is 1, if be 1, then the level of P1.0 is drawn high, P1.0 keeps low level in this time of 1 second, and energising is 1 second in the auxiliary reclay K1 coil, closed 1 second of normal open switch, unlock solenoid valve energising commutation 1 second, the descending unlock button button to telepilot of unlock cylinder commutation 1 second, controller sent unlock command 1 second to dead lock, made dead lock realize release action 1 second.
When num1 equals 15, the num1 zero clearing, in master routine, again the level of P1.0 is dragged down, P1.0 keeps high level in this time of 14 seconds, and outage is 14 seconds in the auxiliary reclay K1 coil, normal open switch disconnects 14 seconds, commutate up return 14 seconds of unlock solenoid valve energising commutation 14 seconds, unlock cylinder, the unlock button button self-return of telepilot 14 seconds.
2, the control of the locking button of telepilot
In master routine, judge whether num1 is 6, if be 6, then the level of P1.1 is dragged down, judge again whether num1 is 7, if be 7, then the level of P1.1 is drawn high, P1.1 keeps low level in this time of 1 second, and energising is 1 second in the auxiliary reclay K2 coil, closed 1 second of normal open switch, lock-up solenoid valve energising commutation 1 second, the descending locking button keys to telepilot of lock-up cylinder commutation 1 second, controller sends locking instruction 1 second to dead lock, makes dead lock realize locking action 1 second.
When num1 equals 6 once more, in master routine, again the level of P1.1 is dragged down, P1.1 keeps high level in this time of 14 seconds, outage is 14 seconds in the auxiliary reclay K2 coil, and normal open switch disconnects 14 seconds, lock-up solenoid valve energising commutation 14 seconds, commutate up return 14 seconds of lock-up cylinder, the locking button keys self-return of telepilot 14 seconds.
3, test number (TN) shows
The accumulation of test number (TN) comes record by the global variable num2 that sets, and num2 is initialized as 0, and whenever num1 is 15 o'clock, num2 has so just realized the accumulation of test number (TN), and shown by 6 eight hop count sign indicating number displays from adding 1.Program two: the programmed control flow process as shown in Figure 5, concrete control procedure is as follows:
The control of 1, the release of telepilot, locking button
The unlock button of telepilot is controlled the actuation of keys of unlock cylinder equally by the break-make of the P1.0 of AT89S51 single-chip microcomputer control auxiliary reclay, only the make-and-break time of P1.0 mouth is realized by the delay function of writing, and the specific implementation process is as follows:
According to the crystal oscillator frequency of single-chip microcomputer, write a time-delay subfunction, in master routine, the level of P1.0 is dragged down, delayed time 1 second, and again the level of P1.0 was drawn high, delayed time 5 seconds, again the level of P1.1 is dragged down, delayed time 1 second, and again the level of P1.1 was drawn high, delayed time 8 seconds, again the level of P1.0 is dragged down, delayed time 1 second, and again the level of P1.0 was drawn high, delayed time 5 seconds, again the level of P1.1 is dragged down, delayed time 1 second, again the level of P1.1 is drawn high, delayed time 8 seconds, circulation so repeatedly, the programmed control flow process is as shown in Figure 5.Among this, P1.0 kept low level 1 second, unlock button button by auxiliary reclay K1 remote controllers 1 second, P1.1 kept low level 1 second, locking button keys by auxiliary reclay K2 remote controllers 1 second, and release button time and locking button time phase difference 6 seconds, the release of telepilot, locking button keys self-return all are 14 seconds.The state of a control that realizes is the same with method one realization.
2, test number (TN) shows
The demonstration of test number (TN) can be described identical with method one, makes corresponding counting variable add 1 certainly by each complete circulation, and show by display.
