Description

The invention relates to object devices, monitoring and controlling endpoint security and alarm devices at an object having uninterruptible power supply devices and performing two-way digital information exchange with notification transmission systems.

A device is known object system for the transmission of notifications "Comet-K" (II1.220.003.TU Security Equipment No. 1/94), containing security lock cables, pulse-width signal block, display units, code lock, power source. The disadvantages of this scheme are the lack of a backup power source and its object control circuits.

A device device is known (RF Patent No. 2226003) containing a microcomputer, an indicator block, a code lock, a communication unit, a first group of security lock cables, the outputs of which are connected to the first group of microcomputer inputs, the first group of inputs and outputs of which are connected to a code lock, the second group of inputs / outputs is connected to the communication unit, and the first group of outputs of the microcomputer is connected to the group of inputs of the indicator block, the group of power control units, the stabilizer block, the second group of protection lock loops, the corresponding outputs of which connected to the second group of inputs of the microcomputer, the second group of outputs of which is connected respectively to the first inputs of the group of power control units, the outputs of which are connected respectively to the inputs of the second group of security lock cables, and the inputs of the group of power control units are connected to the first output of the stabilizer unit, the group of inputs of which is connected with an external power source, and the second output of the stabilizer block is connected to the first input of the microcomputer, and the third output is connected to the second input of the microcomputer.

The disadvantages of this scheme are the lack of a backup power source, charge control circuits and monitoring the status of the backup power source by the object device.

The closest in technical essence to the proposed solution is an object device (RF Patent No. 21110094) containing a microcomputer, an address block, a communication unit, an indication unit, a backup power level unit, a mains voltage supply unit, a backup power supply unit, a power supply, security lock loops , a block of switches, a code lock, the inputs and outputs of which are connected to the first inputs and outputs of the microcomputer, the second inputs and outputs of which are connected to the communication unit, the outputs of the security lock loops are connected to the first inputs of the microcomputer, which are connected to the display unit, the first input of the microcomputer is connected to the output of the network voltage availability unit, the input of which is connected to the output of the power source and the input of the backup power unit, the output of which is connected to the backup power level unit, the output of which is connected to the second input of the microcomputer, the second inputs which are connected by an address block, and the third inputs of the microcomputer are connected to the switch block.

The known circuit device object (UO) works as follows.

After turning on the power to the UO, its microcomputer with built-in ROM and RAM polls the outputs of the block for the presence of mains voltage and the block for the backup power level. If there is mains voltage and the level of backup power is normal, then the microcomputer runs a test diagnostic program. When the diagnostics are completed normally, the microcomputer reads the status of the address block and the switch block, executes the initial settings program and includes a cyclic interrogation of the code lock, the outputs of the mains voltage supply block and the backup power level block, the corresponding lock loops of the constant monitoring guard (for example, such as: “calling the police ”,“ Fireman ”and the like), information about which is recorded in the memory of the microcomputer. The UO microcomputer, during the next communication session with the notification transmission system, through its communication unit carries out two-way digital communication and transmits to the notification transmission system the results of the test diagnostics and the operating status of the UO, and the changed states of the network voltage presence unit and the backup power level unit. If there has been a violation of the status of any of the interrogated security lock loops that are being interrogated, then during the next communication session with the microcomputer notification transmission system, through the communication unit UO will transmit alarm messages to it about the status of the violated security loops.

To install UO under protection, it is necessary to go outside the entrance door of the object of protection and close it, insert the key into the UO code lock. The UO microcomputer reads the key code and polls the status of the outputs of the network voltage availability block and the backup power level block. If the backup power level is below normal, then the microcomputer, through the indicator of the display unit, which is structurally integrated into the code lock, responds accordingly by refusing to arm the UO. If the mains voltage and the backup power level are normal, then the microcomputer, during the next communication session, transmits to the notification system the key code and the status of the outputs of the mains voltage supply unit and the backup power level unit, and receives a command in response to protect the object. After that, the microcomputer begins a periodic interrogation and monitoring of the status of the corresponding (status of “Security”) security lock loops. It includes the “Security” indicator and the “confirmation” indicator on the display unit, which is structurally integrated into the combination lock, which informs that the object has been taken under protection. Similar to the above, but with the polling of the corresponding security loops and the "Security" indicator turned off, the operation of disarming the object is performed. If during the security in the security center there was a change in the status of a security lock loop, then during the next communication session with the security system and the notification system, the security system sends alarm messages to it about all changes in the status of the corresponding security lock cables and will receive a confirmation of the receipt of these messages. Thus, the operator of the notification transmission system has the opportunity to observe the change in events on the plan diagram of the protected object in real time, to make adequate decisions.

The disadvantages of such a UO scheme are:

- lack of monitoring and control by the microcomputer UO of the charge and discharge modes of the backup power source, which increases the number of charge and discharge cycles and does not exclude the possibility of its recharges or deep discharges through internal circuits of power supply units;

- the lack of a circuit to disconnect the backup power source from the discharge and charge circuits;

- the inability to turn off the power to the UO circuits at an unacceptably low voltage level on the backup power source, which leads to the unreliability of the UO operation - malfunctions and improper functioning of the circuits;

- lack of sufficient information in the transmission system of notifications about the state of the backup power supply of the UO and the reason for the loss of communication with the UO.

The aim of the invention is to increase the reliability and information content of the device object.

This goal is achieved by the fact that the object device for monitoring and control of terminal devices of protection and signaling, containing a microcomputer, a communication unit, an indication unit, a unit for backup power level, a unit for the presence of mains voltage, a backup power unit, security lock cables, code lock, inputs the outputs of which are connected to the first inputs and outputs of the microcomputer, the second inputs and outputs of which are connected to the communication unit, the outputs of the security lock cables are connected to the third inputs and outputs of the microcomputer, the group of outputs of which is is dined with an indication unit, the first input of the microcomputer is connected to the first output of the network voltage availability unit, and the second input of the microcomputer is connected to the first output of the backup power level unit, the first and second keys are inserted, and the stabilizer unit, the first input of which is connected to the second output of the backup level unit power supply, the input of which is connected to the output of the first key, the first input of which is connected to the first switching output of the microcomputer, the second switching output of which is connected to the first input of the second key, the output of which is via bl ok the backup power supply is connected respectively to the second input of the first key, and the second input of the stabilizer unit is connected to the second output of the network voltage availability unit, the third output of which is connected to the second input of the second key.

The drawing shows a block diagram of a device object.

The object device contains a microcomputer 1, security interlock cables 2, communication unit 3, indicator block 4, code lock 5, stabilizer block 6, first key 7, backup power level unit 8, backup power supply 9, second key 10, block for the presence of mains voltage 11. The object device (UO) works, for example, as follows.

After connecting the power to the input of the unit for the presence of mains voltage 11 from an external voltage source, the unit for the presence of mains voltage 11 from the first output generates a signal about this to the first input of the microcomputer 1. From the third output of the unit for the presence of mains voltage 11, the voltage is supplied to the second input of the second switch 10. And from the second output of the presence of the mains voltage 11, voltage is supplied to the second input of the voltage stabilizer 6, from the outputs of which the corresponding stabilized voltages are supplied to the radio elements of the UO circuit. Microcomputer 1 UO (with built-in ROM and RAM), after the supply voltage is supplied to it, it starts to execute the program sewn into the ROM, and through the first switching output it outputs a signal to the first input of the first key 7, which will connect the voltage from the output of the backup power supply via this signal 9, through the backup power level block 8 to the first input of the voltage regulator 6. And the second input of the microcomputer 1 from the first output of the backup power level block 8 will receive a signal about the presence and level of voltage on the backup power source. Next, the microcomputer 1 polls the state of its first and second inputs. If the microcomputer 1 determines that the voltage from the external voltage source and the voltage level of the backup power source is normal or lower than the norm, then the microcomputer 1, through the second switching output, outputs a signal to the first input of the second key 10 about recharging the backup power source. Having received the signal from the microcomputer 1, the second key 10 exits the output to the input of the backup power supply unit 9. The backup power supply unit 9, to the circuits of which a backup power source (for example, an acid battery) is connected, charges the backup power source. The voltage from the backup power supply unit 9, through the first switch 7, through the backup power supply level unit 8 is supplied to the voltage regulator 6 comparison circuit. The voltage level at the second input of the voltage stabilizer 6 is slightly higher than the voltage level at the first input, therefore, if there are voltages at both inputs of the stabilizer voltage 6, its power is supplied through a comparison circuit from the input with a higher voltage. Next, the microcomputer 1 runs a test diagnostic program. With the normal completion of the diagnosis, the microcomputer 1 performs the initial settings necessary for operation in the MA. Then includes a cyclic poll: code lock 5; the outputs of the block the presence of mains voltage 11; unit level backup power 8; corresponding security lock lock loops 2 for constant monitoring (for example, such as: “calling the police”, “fireman” and the like), information about which is appropriately pre-recorded in the memory of microcomputer 1. During the next communication session with the notification system of microcomputer 1 through the unit Communication 3 carries out two-way digital communication according to the appropriate algorithms with the notification transmission system and transmits the last message on the results of test diagnostics, the current state of the UO, the states of the block of the presence of mains voltage I 11 and the backup power level block 8. If the microcomputer 1 after the next polling of the signal from the output of the network voltage availability block 11 determined that the voltage from the external voltage source is present, and on the backup power level block 8, the voltage level of the backup power supply became equal to or higher than the permissible values, in order to avoid overcharging the backup power supply of the microcomputer 1, through the second output it will remove the signal from the first input of the second key 10, which in turn will turn off the voltage supply to the backup unit about power 9. And in order to exclude the discharge of the backup power source in the presence of voltage from an external voltage source, through the circuit of the backup power level block 8 of the microcomputer 1, through the first switching output it will remove the signal from the first input of the first key 7, which in turn will turn off the backup source power supply from the discharge circuits of the backup power level block 8. Next, at the next polling of the signal from the output of the backup power level block 8 to determine the status of the backup power supply, microcomputer 1 during the second of the move, through the first switching output and the first switch 7, will briefly connect the back-up level unit 8 to the back-up power unit 9. If the microcomputer 1 after the next polling of the signal from the output of the mains voltage supply unit 11 determines that there is no voltage from the external voltage source, then microcomputer 1, through the first switching output, through the first switch 7, through the back-up level block 8 will connect the voltage to the voltage regulator 6 from the back-up power supply 9. If, then, during the next interrogation, the signal and from the block of the backup power level 8 and the block of the presence of the mains voltage 11, the microcomputer 1 determined that the voltage level of the backup power source became lower than the permissible norm, and the voltage from the external voltage source does not go to the UO, then the microcomputer 1 during the next communication session with the notification system , through the communication unit 3 transmits the last state of the signals from the unit for the presence of mains voltage 11 and the unit for the backup power level 8 and asks for permission to turn off the power to the UO. After obtaining permission, the microcomputer 1 will turn off the signal at the first switching output and thereby the signal at the first input of the first switch 7, which in turn will turn off the voltage supply, through the back-up level unit 8 to voltage regulator 6, and all UO circuits will be de-energized. The last procedure is necessary to protect the microcomputer 1 from undervoltage supply, at which the sequence and correct execution of the ROM program commands become unpredictable. After restoring the supply of external voltage to the block of the presence of mains voltage 11, the UO will be included in the work similarly to the sequence described above at the beginning of the description of the operation of the UO. If during the operation of the MA there were violations of the state of any of the interrogated security lock loopback cables 2, then during the next communication session with the notification system of microcomputer 1, it will send alarm messages about the status of broken security lines 2 through the communication unit 3.

To install UO under protection, it is necessary to go outside the entrance door of the object of protection and close it, insert the key into the UO code lock. The UO microcomputer reads the key code and polls the status of the outputs of the network voltage availability block and the backup power level block. If the backup power level is below normal, then the microcomputer, through the indicator of the display unit, which is structurally integrated into the code lock, responds accordingly by refusing to arm the UO. If the mains voltage and the backup power level are normal, then the microcomputer, during the next communication session, transmits to the notification system the key code and output status of the mains voltage supply unit and the backup power level unit and receives a command in response to protect the object. After that, the microcomputer begins a periodic interrogation and monitoring of the status of the corresponding (status of “Security”) security lock loops. It includes the “Security” indicator and the “confirmation” indicator on the display unit, which is structurally integrated into the combination lock, which informs that the object has been taken under protection. If the state of any of the security lock loops has changed during the security process, then during the next communication session between the security system and the notification system, the security system will send alarm messages to it about all changes in the status of the corresponding security lock loops and will receive a confirmation of the receipt of these messages. Thus, the operator of the notification transmission system has the opportunity to observe the change in events on the plan diagram of the protected object in real time and make adequate decisions. Similar to the above, but with the polling of the corresponding security loops and the "Security" indicator turned off, the operation of disarming the object is performed. The UO circuit described above with the control and management by the microcomputer UO of the charge and discharge modes of the backup power source allows:

- reduce the number of cycles of its charge and discharge, as well as eliminate overcharges and deep discharges, which increases the service life of the backup power source;

- turn off the power of the UO circuits at an unacceptably low voltage level on the backup power source, which leads to malfunctions and improper functioning of the UO circuits (especially microcomputer programs).

The above advantages can improve the reliability of the UO. And informing the object device of the notification system about the status of the backup power source and generating a request for permission to turn off the power of the UO circuits at an unacceptably low voltage on the backup power supply increases the information content of the UO.
