Description

The invention relates to automation and can be used in various vending machines.

The purpose of the invention is to increase the functional reliability of the device.

Figure 1 presents the functional diagram of the device; 2 and 3 show the algorithms of the device operation.

The device comprises an information receiving and processing unit 1, a fixed memory block 2, RAM blocks 3 and 4, interface blocks 5 and 6, an operation mode switch 7, a block 8 of actuators and keys for issuing goods, a control key block 9 , a banknote receiving unit 10, a receiving unit protection unit 11, a backup power source 12, a power source 13, a control key 14, a fault signaling line 15, an indicator 16, a power source switch 17, a print output 18, and an information transfer unit 19.

The device works as follows.

In the standby and customer service modes, the program block 1 for receiving and processing information, working according to the corresponding program recorded in block 2 of the program permanent memory, polls the fault sensors included in the external devices through the first block 5 interfacing. When a malfunction is received from any of the sensors, software block 1 generates a code for this malfunction and writes it to the second operative memory block 4 for: subsequent output to the indicator 16. Block 1 sends a command to block 11 to close the receiving mask of the machine and return of 10 currency accumulated in the block. Then block 1, through block 5, gives the command to disconnect the machine from the network to the control key 14. As a switching unit, you can use an electromagnetic relay or an electronic key. The control key 14 disconnects the power source 13 from the network and issues a fault on line 15. The fault signaling line 15 may be protruded, for example, to the attendants ’duty room. When the mains supply voltage fails, the switch 17 triggers, which blocks the inputs of the first 3 and second 4 blocks of RAM so that unauthorized changes to the information stored in these blocks during the transients associated with the disappearance of the supply voltage do not occur. x After disconnecting power supply 13

The first 3 and second 4. RAM blocks remain powered by the backup source 12.

If the device is used in a cash register (for example, for the sale of train tickets), then to increase the reliability of storing information about the malfunction (for example, in the case of a malfunction of the indicator 16,

0 RAM or the second interface unit 6) a malfunction code is printed on the control tape before disconnecting the machine from the network.

If the machine in which it is used

5 device, included in the group of automata integrated into the system of centralized collection and processing of information, then to increase the efficiency of service, the fault code together with the number of the automaton

0 is transmitted to the data collection system before disconnecting the machine from the network.

When the machine is turned on in the network, it does not immediately go into customer service mode, but for a certain time (for example,

5 30 s) on the indicator 16 highlights the contents of the second RAM block 4, if it is not zero.

When the machine is operating in all modes, the information to be displayed on the indicator 16 is recorded in block 4 and displayed on indicator 16 from block 4 through block 6. Zero flashes in standby mode, in customer service mode the amount of money received by block 10 receiving, in the diagnostic mode - diagnostic or statistical (for example, the total amount of money in the cash register of the machine, the total quantity of goods sold, etc.) information stored in the first block 3 of the operational memory.

0 After power is turned on, the contents of the second RAM 4 are checked. If it contains zeros, it means that the machine was turned off not by accident, but from the waiting mode by the service personnel. In this case, the machine immediately goes into standby mode or in diagnostic mode, depending on the position of the operation mode switch 7.

0

If the information in block 4 is different from zero, it means that the machine was turned off automatically as a result of the occurrence of a fault, and in block 4 the code of this

5 faults. In this case, the malfunction code from block 4 is transmitted to the indicator 16, on which it is displayed 30 seconds or until reset by the Return button in block 9 of the control keys. After that, the machine goes into standby mode or

In diagnostics mode, maintenance personnel can check operation in detail.

If the machine is turned off as a result of an improper | / 1 power supply 13 or for an unauthorized disappearance of power supply in service mode (pack, block 4 stores the amount received from the customer. After switching on the machine, it is displayed on the display 16 which eliminates controversial situations between the buyer and the service provider.
