Implementation of the invention

The personalized engine start system of the self-propelled vehicle 1 is made in the form of a single unit mounted in the housing 2. The housing 2 is mounted at the driver's workplace in the self-propelled vehicle 1.

In the case 2 there is a controller 3, which acts as a code comparison unit, which contains a permanent memory 4.

The controller 3 controls the engine blocking device installed in the housing 2, made in the form of a circuit breaker 5. The circuit breaker 5 is made in the form of a predominantly contact electromagnetic relay or a non-contact electronic circuit breaker in the form of a thyristor. The breaker 5 provides opening and closing of the start control circuit 6 of the engine of the self-propelled machine 1, preferably the starter circuit for starting the engine of the self-propelled machine 1.

The controller 3 controls the system status signaling device 7 installed in the housing 2, which is mainly represented by two light indicators of the system status, for example, a signal green indicator and a signal red indicator.

In case 2, a proximity reader 8 is installed, which identifies the codes of the master key 9 and working keys 10 by radio frequency identification of the tags of the master key 9 and working keys 10.

The master key 9 and working keys 10 are, for example, personalized pass cards for employees to enter an enterprise or workplace, while the personalized pass cards contain a chip 11 containing a unique identification code; in addition, personal passes can be applied to the pass cards. data of 12 employees in the form of a photograph, last name, middle name, position, etc.

The controller 3 is powered from the power supply unit 13 of the self-propelled machine 1 through the power circuit 14 or from an individual power supply unit 13. The power supply of the controller 3 is turned on and off by the power switch 15, which is preferably the ignition key of the self-propelled machine 1.

The system works as follows.

Assembled in a single housing 2, the system is mounted at the driver's workplace in a self-propelled vehicle 1 in addition to the regular engine start blocking system, made in the form of an ignition key. The breaker 5 is connected to a break in the start control circuit 6 of the engine of the self-propelled machine 1. The controller 3 is connected to the power supply 13 through the power circuit 14 through the power switch 15.

The controller 3 is loaded with a program for recording and comparing the codes of keys 9 and 10, for controlling the circuit breaker 5 and the signal indicators of the signaling device 7. The program has a service and operating modes. At the same time, in the service mode, the key codes 9 and 10 are recorded and (or) deleted in the ROM 4 memory, in the operating mode, the key codes 9 and 10 are compared with the key codes 9 and 10 stored in the ROM 4 memory, and permission is given to start the self-propelled engine. machines 1.

The employee appointed in accordance with the established procedure at the enterprise responsible for adding or removing working keys 10, when the device is first turned on after installation and connection on a self-propelled machine 1, the service mode is activated, in which the master key 9 of the employee is assigned.

When the service mode is switched on, the indicators of the annunciator 7 are active (they are on continuously). Bringing the alleged master key 9 into the zone of the contactless reader 8, it reads the unique identification code of the master key 9 by means of RF identification of the chip tags 11, transmits and writes the read code to the memory of the ROM 4 of the controller 3, while, in case of successful writing of the code, green indicator indicator 7 alternately, with a frequency of 1-2 seconds, blinks three times and automatically switches to the operating mode. The first key recorded in the ROM memory 4 of the controller 3, after turning on the device, is the master key 9.

The operating mode is switched on automatically when power is supplied to the controller by the power switch 15. In the operating mode, the red indicator of the annunciator 7 is continuously on, the green indicator of the annunciator 7 has no indication - it is not lit.

After writing to the memory of the ROM 4 code of the master key 9, it is used to write to the memory of the ROM 4 of the codes of the working keys 10 (assignment of the working keys). To write the working key 10 of a new user into the ROM 4 of the controller 3, it is necessary to transfer the system to the service mode, the transition is carried out by applying a personalized pass card that carries the function of the master key 9 to the reader 8. When the service mode is turned on, the indicators of the signaling device 7 are continuously). Bringing the supposed working key 10 into the zone of the contactless reader 8, it reads the unique identification code of the working key 10 by means of RFID tags, transmits and writes the read code to the memory of the ROM 4 of the controller 3, while, in case of successful recording, the green indicator of the indicator 7 alternately blinks 3 times at intervals of 1-2 seconds, after which it is possible to write to the ROM memory 4 the code of the next working key 10 by applying a personalized pass card for a new employee who is allowed access to work on a self-propelled machine 1. After writing to the ROM memory 4 codes of all the necessary working keys 10 employees who are allowed to work on the self-propelled machine 1, the power of the controller 3 is turned off by the power switch 15, and after the power is turned on by the switch 15, the system automatically switches to the operating mode.

After recording the working keys 10, all employees who have a personalized pass card with a code stored in the ROM memory 4 are assigned the function of the working key 10. The working key 10 allows personalized access to work on a self-propelled machine. By applying a personalized pass card with the function of a working key 10, the unique identification code of which is stored in the ROM 4 memory, the red indicator of the signaling device 7 turns off and the green indicator of the signaling device 7 turns on, the breaker 5 closes the launch control circuit 6, providing an opportunity for a limited program of the controller 3, for example , 30 seconds time, start the engine of self-propelled machine 1, provided in the design of the machine with a starter, turned on by the ignition key. Similarly, personalized access to start the engine of a self-propelled machine is provided to all employees with a personalized pass card, whose chip code 11 is stored in the ROM memory 4 of the controller 3.

Applying any pass card to the reader 8, not entered into the memory of the ROM 4, the red indicator of the signaling device 7 will blink three times with a frequency of 1-2 seconds and will continue to burn continuously, while the controller 3 will not send a signal to the breaker 5, which will not close the control circuit start 6 of the engine, since the start control circuit 6 will remain open, the engine of the self-propelled machine 1 will not start, there is no access to start the engine.

To remove the working key 10 of the user from the ROM 4 of the controller 3, it is necessary to transfer the system to the service mode, the transition is carried out by applying a personalized pass card that carries the function of the master key 9 to the reader 8. When the service mode is turned on, the indicators of the signaling device 7 are active (they are on continuously ). Bringing the working key 10 supposed to be deleted from the memory of the ROM 4 to the zone of the contactless reader 8, he reads the unique identification code of the working key 10 by means of radio frequency identification of the tags, compares the read code with the ROM 4 of the controller 3 available in the memory, and if this the code is already in the ROM memory 4, it is erased, the red indicator of the signaling device 7 alternately, with a frequency of 1-2 seconds, blinks 3 times. After one working key 10, it is possible to erase the code of the next working key 10 from the ROM memory 4 by applying a personalized pass card for a new employee who was previously allowed access to work on a self-propelled machine 1. After erasing the codes of all necessary working keys 10 from the ROM memory 4 employees who are prohibited from working on the self-propelled machine 1, the power of the controller 3 is turned off by the power switch 15, and the system automatically switches to the operating mode after the power is turned on by the power switch 15.

If the ROM memory 4 is full, then when writing the next working key 10, the green indicator and the red indicator of the signaling device 7, with a frequency of 1-2 seconds. blink 3 times, it means there is a write error, the label has not been added to the ROM memory 4.

The program of the controller 3 provides for quick clearing of the memory and deletion of all keys stored in the ROM 4 memory, the so-called return to factory settings. To clear the memory of the ROM 4 of the controller 3, it is necessary to transfer the system to the service mode, the transition is carried out by applying a personalized pass card that carries the function of a master key 9 to the reader 8. When the service mode is turned on, the indicators of the signaling device 7 are active (burn continuously). Next, you need to apply the master key 9 to the reader 8 the number of times specified by the controller 3 program, while the green indicator and the red indicator of the signaling device 7 blink at intervals of 1-2 seconds according to the number of times specified by the program, the device reboots, the memory is cleared, you can write a new master - key 9 and working keys 10 as described earlier.

Each impact on the reader 8 is accompanied by a corresponding light signal indication of the signaling device 7.

The advantage of the system is that it is connected only with the self-propelled machine 1, during operation and when making changes to the ROM 4 does not require connection to third-party power sources, does not require the connection of additional devices for programming.

Prevention of unauthorized access to the control of the self-propelled machine 1 is ensured by installing a personalized engine start system for each unit in the fleet of self-propelled machines, and each employee, in view of the access control regime of the enterprise, has a personalized pass card, while it becomes possible to provide a certain employee access to the management of a certain list of self-propelled machines, eliminating the risk of unauthorized access to starting the engine and using the machine.

The person responsible for the operation of the equipment, having a personalized pass card, can be written to ROM 4 using a contactless reader 8 as a master key 9 on any number of self-propelled machines 1. The owner of the master key 9 recorded in ROM 4 has the ability to transfer the device to service mode for entering data into the ROM 4 for recording the working keys of 10 employees admitted to the management of self-propelled machines. Personalized access to work on a self-propelled machine eliminates the possibility of unauthorized access by employees of the enterprise who do not have permission to work on the machine, thereby increasing safety during operation.

The tests of the system for personalized engine start of a self-propelled machine confirmed the operability, safety and reliability of the design. During the test, the possibility of starting the engine of a self-propelled vehicle was confirmed only by drivers who have permission to use a self-propelled vehicle with their personal passes.

The technical solution is industrially applicable, since it was manufactured and tested on a self-propelled machine, namely on a self-propelled forklift, and is intended for use, in particular, in aluminum smelters.
