Description

The proposed technical solution relates to the security system of real estate objects, namely, to monitoring and security device complexes, and is intended for placement of fire and security alarms at small objects isolated from the external environment, connecting security and fire alarm reception and control points to modern networks data transmission, as well as automation of monitoring processes of the necessary characteristics and parameters in a complex of rooms that are not observed for a short time (qua Tir, cottage) and for a long time (hut, maintenance-free industrial objects).

Known monitoring system "Censor" (RU 86027, G08B 25/00, 2009), which is designed specifically to monitor the status of telecommunications facilities. As a communication channel used telecommunication channels. Therefore, the known system cannot be used to monitor and protect real estate objects to which telecommunication cables are not connected.

Closest to the claimed one is a complex of monitoring and security devices (RU 78742, B60R 25/00, G08B 25/10, 2008), designed for centralized protection of real estate through video monitoring and prompt response at the first sign of illegal actions in relation to protected object. The well-known complex was created specifically to perform these functions and is not intended for integrated monitoring, i.e. monitoring temperature, humidity in the room, monitoring the status of cables, etc., i.e. the complex is not universal.

The technical task is to expand the functionality, increase reliability and ensure the universality of the security complex by "adjusting" the latter to various objects of protection and monitoring by connecting additional supported devices and hardware and software.

The essence of the technical solution lies in the fact that the security complex, including an object device (OS) with a microcontroller (MK) and a power source connected by communication channels to a dispatch center (DC), according to claim 1, is equipped with a radio receiver and a backup power source - the battery, MK is made with the ability to receive, process and transmit information to the DC through Ethernet and / or GSM channels when wireless sensors (DB), wire sensors (PD), a TOUCH MEMORY key reader, a temperature sensor ( DT), a resource counter with a pulse output, as well as with the ability to charge the battery and control the fire loop, while the op-amp is configured to parallelly connect compatible external expansion modules (BMP) to its inputs.

In addition, compatible BMPs are made with the possibility of implementing additional functions, namely:

- reading readings from additional resource meters through a pulse output and measuring the voltage difference in three phases (claim 2 of the formula),

- measuring temperature and relative humidity at one point (claim 3 of the formula),

- access authorization of the person opening the door, access control to the facility and use of equipment management commands. An external module is connected - an intelligent reader "IS-485" or "IS-485. The gatekeeper "(paragraph 4 of the formula),

- the ability to connect at least eight additional sensors with outputs of type "dry contact", or control at least eight copper cables in three states: "normal", "operation", "short circuit" (open circuit) (Clause 5 of the formula) ,

- alarm when open moisture appears in the room, as well as the issuance of a control signal to shut off the pipeline when fixing the fact of leakage. An external module is connected - a water leakage sensor "DPV" (paragraph 6 of the formula).

Moreover, the OS contains an output for connecting a fire loop and detector according to claim 7. Fire loop control is carried out according to four states: “fire”, “norm”, “open loop”, “loop short circuit”. Connecting a fire detector (PI) through the loop allows you to control not only the PI, but the loop itself for damage. For example, it is possible to record damage from fire before the PIs have triggered.

The expansion of functionality consists in giving new functions to the operating monitoring and control system, which is ensured by connecting to the OS and MK the devices listed in paragraph 1 of the formula, as well as through hardware and software configuration (equipment) (paragraphs 2-7 of the formula).

The inventive security complex provides the versatility and complexity of the security system, as well as high efficiency for both standard and remote, both for monitored and unobservable objects of protection in equal measure. And what is especially valuable, the claimed complex is not distinguished by the redundancy of the functional, i.e. lack of unused functions, as BMP, providing functional filling of the security complex, are equipped depending on customer requirements, technical and economic feasibility. The complex is modular, which makes it possible to supplement the functionality of the complex even during its operation.

The inventive complex is highly reliable for remote objects of protection due to the use of several communication channels and the availability of a backup power source (battery), as well as the ability to duplicate information through two communication channels to different dispatch centers.

The presence of a radio receiver allows monitoring at objects of various structural complexity.

The parallel connection of the sensors DB and PD improves the reliability and speed of the claimed complex, and also leads to savings in cable lines, taking into account the length of the cable between the objects of protection.

Figure 1 presents a diagram of a security complex, figure 2 is a diagram of the connection of BMP to the OS of the claimed security complex. Figure 3 illustrates the connection of the PI in a two-wire circuit (a) and in a four-wire circuit (b).

The complex includes an object device OS 1 with a microcontroller MK 2 and a power source 3. OS 1 via communication channels 4 (ETHERNET, GSM) is connected to the control center DC 5. OS 1 also includes a backup power source - battery 6 and radio receiver RPU 7. K MK 2 inputs are connected to PD 8 wired sensors with a dry contact type output with a closed-open output state, a TOUCH MEMORY key reader 9, a DT 10 temperature sensor, a resource counter 11 with a pulse output, and a PI 12 fire detector. Wireless OBD 13 sensors are associated with radio reception RPU 7 device via a radio channel.

The compatible external expansion modules BMP 14 are connected in parallel. Moreover, additional resource counters 15 through a pulse input can be connected to one BMP 14, as well as additional sensors 16 with outputs of the type of "dry contact". Additional sensors 16 can be connected in an amount of up to 8 pieces. At least eight copper cables can be monitored in three states: “normal”, “trip”, “short circuit” (open).

OS 1 receives and processes information from devices connected to it, and transfers it to DC 5, and also performs the function of charging the backup battery 6. To provide backup power, OS 1 has a dedicated input for connecting one battery 6, through which the device is powered at the time of disconnecting the main power, as well as charging a discharged battery from the main power source 3. To use the backup battery 6, it is necessary to close the electric circuit with the “BAT” jumper. To deactivate the backup power supply without physically disconnecting the battery 6 from OS 1, you must open the jumper "BAT".

OS 1 allows you to connect any device that has an external RS-485 or RS-232 or CAN interface. In this case, the OS 1 acts as the organizer of the communication channel without processing data from this device. The maximum data transfer rate is 57.6 kbit / s. The receiver is any application that understands the data format and is able to receive data through a TCP connection to the selected port. Supported data networks - Ethernet (TCP, UDP, PPPoE); GSM (GPRS).

Data exchange via Ethernet is carried out via TCP in two modes:

- constant data output in DC 5 at regular intervals (from 1 second to 255 seconds, by default - 3 seconds);

- when any input changes, the data is sent to DC 5 immediately.

Data exchange via the GSM channel is carried out through the GPRS service. Data on the GSM channel is transmitted only from OS 1 to DC 5, but not back.

The main communication channel is Ethernet. In case of loss of communication on the main channel, data will be transmitted on the backup channel, by default the GSM channel is used. When communication is restored on the primary channel, the backup channel becomes inactive.

There is the possibility of simultaneous operation both on the main and on the backup channels.

RPU 7 with a radio antenna transmits information from wireless sensors - DB 13 radio sensors. DB 13 radio sensors control the room, RPU 7 processes information from DB 13 and based on this changes the status of the protection bit and transmits to the input of OS 1. The protection bit can have the following states: disarmed ”,“ armed ”,“ hacking security ”. DB 13 can have the states: “operation”, “normal”, “malfunction”. The status of the database 13 is taken into account only if the protection bit is not in the “disarmed” state. The guard bit is set by control devices compatible with RPU 7.

The key reader 9 “TOUCH MEMORY” works on the “1-Wire” interface with emulation of the DS1990A iButton key.

As DT 10, the “DS 1821” sensor manufactured by “Dallas Semiconductor” is used. It works via the “1-Ware” digital interface, transmitting to the OA 1 a discrete value of the measured temperature. The design of the sensor allows you to place it directly at the measuring point. Temperature measurement range (-55 ... + 75) ° С, measurement accuracy 1 ° С.

The resource counter 11 with a pulse output is connected to the pulse input of the OS 1, the information from it is stored in its own non-volatile memory in certain cases. At the time of power off of the OS 1, the counter 11 does not save the information on its own. The resource counter 11 perceives a pulse lasting more than 20 ms. Each new impulse increases the internal variable - counter by one. Pulses less than 20 ms are discarded as interference.

Fire loop control.

In FIG. For power supply PI 12 and communication with OS 1 is carried out simultaneously on two wires. Additionally installed resistors:

R _add = 330 Ohm, R _ok = 3.9 kOhm. Possible states of a two-wire loop:

- “loop interruption” is recognized when the current in the loop is <200 MkA;

- the “loop standard" is recognized at a loop current> = 200 MkA and <5 mA;

- “fire” is recognized when the current in the loop> = 5 mA and <40 mA;

- “loop short circuit” is recognized when the loop current> = 40 mA.

On Fig power supply PI 12 and the connection of Pi 12 with OS 1 is carried out separately on two pairs of wires. The outputs of the PI 12 are made on the principle of "dry contact".

Resistors: R _add1 = 2.2 kOhm and R _add2 = 2.2 kOhm, they do not depend on the type of PI 12.

Possible states of a four-wire loop:

- “loop break” is recognized when the loop current <200 MkA;

- the “loop standard" is recognized at a loop current> = 200 MkA and <4.2 mA;

- “fire” is recognized when the current in the loop> = 4.2 mA and <40 mA;

- “loop short circuit” is recognized at a loop current> = 40 mA.

The fire loop can be turned off / on from DC 5 on command. If a two-wire circuit is used, then when the loop is disconnected, the power from the PI 12 is removed, when connected, the power is supplied. Thus, PI 12 operating on a two-wire circuit can be restarted at any time by command.

Compatible BMP 14s are connected in parallel via junction boxes. The maximum distance from the most remote object to OS 1 of the security complex does not exceed 100 m. In some cases, it is possible to organize communication between BMP and OS, located at a distance of up to 1200 m, in accordance with the RS-485 data transmission standard.

The number of BMP 14 connected is up to 14 pieces in one security complex (BMP brands - EPU-485, DVT-485, MSI-485, IS-485, 8SK-485, UM-485, DPV, IS485_Privitnik).

Example. The complex performs its functions when used to monitor and protect a country house (cottage), in which there is no wired Internet. The main communication channel is wireless GSM. In this case, wire sensors are used, as a rule.

- MC485 pulse counter for taking readings from the pulse output of an electricity meter equipped with a pulse output, and transmitting these readings to the DC.

Data from the monitoring and security equipment listed above is received via the GSM channel to the input of the op-amp, where it is converted into signals. For example, when opening a door - information on opening an electric circuit - into a signal for opening a door. When reading readings from an electricity meter, the input electrical pulses are converted into a digital form in the form of a sum of pulses of a certain type. Signals are transmitted via the GSM channel to the DC, where they are processed and displayed using the software interface in a form accessible to the dispatcher.

When the power is turned off, the equipment switches to the backup power supply from the backup source - the battery.

In case of hacking, the signal from the vibration / shock sensor or reed tamper sensor is fed to the op-amp inputs and transmitted to the DC through the GSM channel. The dispatcher sees the signal and transmits information to the appropriate security company, which responds to the signal.
