t

The invention relates to fire alarm technology and can be used to collect information on dedicated lines of communication from on-site devices installed 5 at public facilities and in citizens' apartments, to display it on a special display panel and to transmit along the communication line. centralized monitoring system .n

It is known a central locking signal device containing sensors of state of the object that are connected to the switch, output connected to the comparison unit, short-time display unit 15 and memory blocks that are connected to the constant-display unit through logic elements; The synchronization unit controls the operation of the memory blocks and the logic elements 20 via a frequency divider. The switch alternately connects the sensors of the state of the objects to the input of the comparator unit, to the other input of which the information 25 about the signal of the same sensor received in the previous interrogation cycle is entered from the corresponding memory cell slot. If the data entered on both inputs to the comparison block is the same, then the information: from - correspond to: the memory cells of the memory block -30

It enters the constant indication block, in which the state of the object is displayed. If the data entered into the comparison unit is different, then the information from the output of the sensor-state of the object is recorded in the short-term indication unit for processing by the operator. After processing, this information is supplied for display in a permanent display unit.

This signaling device has the following disadvantages: it does not have the ability to change the monitoring mode of object devices, which would allow to exclude the indication of certain types of information coming from the sensors of the state of objects and losing its value in some time intervals; there is no possibility of transmitting information about the state of objects to the centralized monitoring system; In addition, the reception of information from the object state sensors ceases during the processing time by the operator of the incoming message, which can lead to the loss of messages about short-term states of the object.

The closest technical solution to the proposed device is a signaling device 21 including a synchronization unit, the first output of which is connected to the switch's address input, the second to the input of a frequency divider and control (the input of the enable signal generator, the output of which is connected to the first signal input display units, object state sensors, second outputs of the synchronization unit are connected to object state sensors, which are connected to the switch through the decoder, and it is connected via a memory block This is the resolution driver, to which the synchronization unit and the frequency divider are also connected.

The signaling device sequentially polls the object state sensors, generates an integral evaluation signal of the object state and displays this state on the display element.

The disadvantages of this device for signaling are that the information content of the device is small, since it provides control and display of only four states of the object; and the inability to change the control mode of the object devices, which would eliminate the indication of certain types of information, actions from the sensors of the state of the object, and some time intervals its value} the lack of possibility in the display unit of storing information, which makes it difficult to obtain information about short-term revozhnyh and emergency state x of the object; in addition, the inability to transfer information about the state of objects to the centralized monitoring system.

The purpose of the invention is to enhance the functionality and increase the reliability of the device.

The goal is achieved by the fact that a pulse shaper, an address unit, an analog-to-digital converter and an information output unit are inserted into the signaling device. The first output of the synchronization unit is connected to the input of the address block; the second output of the synchronization unit is connected to the input of the FORMS at the pulses, controlling the input of the analog-digital converter / clock input of the display unit, the memory control unit and the first input of the information output unit. The outputs of the switch are connected to the control inputs of the display unit and to the first control inputs of the sensors of the object state, the second control inputs of which are connected to the output of the pulse former. The outputs of the object state sensors through a series-connected analog-to-digital converter and. the decoder is connected to the information input of the memory unit, one rtSsmeoao ffRt5t 5pci-fe is a yoyyon c & the second signal input of the display unit. The other output of the memory unit is connected to the second input of the information output unit and the first input of the resolution signal conditioner, the second input of which is under. It is connected to the first output of the address setting block, the second output of which is connected to the third input of the information output block. The output of the division, the frequency bodies is connected to the third signal input of the display unit.

Introduction of a pulse shaper to a device, for example, on a trigger and an analog-digital converter, allows one to interrogate on-site devices with both a positive DC voltage and a negative DC voltage, which significantly increases the number of controllable states of the object.

Introduction to device address

Block 0 makes it possible to change the monitoring modes of the object devices and to exclude the display and transmission of certain states of the object.

Introduction to Output Unit Device

The f information allows the transfer of information about the state of the object to the central monitoring system.

The drawing shows a block diagram of the device. .

The device contains a group of sensors 1 state of objects, block 2 synchronization, switch 3, driver 4 pulses, frequency divider 5, address block b, analog-to-digital converter 7, decoder 8, block

5 9 memories, the resolver of the resolution signal 10, the display unit 11, the information output block 12.

The synchronization unit 2 sequentially generates address signals to the address inputs of the switch 3 and the address block b. When the next address is generated by the synchronization unit 2, the switch 3 sends a signal to the first input of the corresponding sensor 1 of the object state, which ensures interrogation of the on-site device connected to the sensor of the object state by bus 13. Interrogation of the object devices representing two parallel-connected veifeii. .3 X1 each of which includes a diode and resistors, is made by a two-pole p-voltage with the help of a 4-pulse driver;

which is carried out by the clock pulses coming from the second output of the synchronization unit 2. At the beginning of the interrogation cycle of the object device, the pulse shaper 4 is reset and a positive voltage is applied to the second input of the object state sensors. After half the polling time of the object device from the synchronization unit 2, the next clock pulse is applied, which changes the state of the driver .4 pulses to the opposite, and a negative voltage is applied to the second sensor inputs of the object.

During the positive voltage on the second sensor of the object's stand, the state of one branch of the on-site instrument is analyzed, and during the negative voltage, the second branch is analyzed. Depending on the state of the branch of the object device, the voltage value at the output of the sensor 1 of the state of the object will be different.

The introduction of a two-pole constant voltage interrogation of object devices and, accordingly, a 4 pulse generator and an analog-digital converter 7 has significantly increased the number of monitored conditions of object devices.

The voltage from the output of the sensor 1 of the state of the object is fed to the input of the analog-to-digital converter 7, which contains directly the voltage converter - the code and the memory register. The conversion of voltage into a code, the recording of this code into the corresponding cells of the memory register under the action of a clock pulse from the second output of synchronization unit 2 takes place in the analog-digital inverter 7 for each field of the polling voltage separately. Thus, at the end of the polling cycle at the output of the memory register of the analog-digital converter there is information about the state of the object device. This information is fed to the input of the decoder 8, which has a number of outputs equal to the number of monitored states of the on-site devices.

Thus, each state of the object device corresponds to a signal at one of the outputs of the decoder 8. Signals from the output of the decoder 8 are recorded under the action of a clock pulse from the second output of the synchronization unit 2 into the corresponding cells of the unit. .9 memory. At the same time, a signal is output from the output of the switch 3 to the corresponding input of the display unit 11. This signal permits the copying of information from memory block 9 into the memory cells of display block 11, which are individual for each monitored object. The census takes place at the end of the polling cycle of the object state sensor under the action of a clock pulse coming from the second spin of the synchronization unit 2. Thus, the census of information from memory block 9 into the memory cell of display block 11 occurs at the end of each poll cycle-sensor 1 of the object state. If the information coming from the storage unit is the same, then the recorded

earlier information. When a new information appears, it is recorded in other memory cells of the display unit 11. The operator processes the received information displayed on the special CBefOBOM board, takes the necessary measures and returns the occupied memory cells of the display unit 11 to the initial state. This algorithm of the display unit operation involves the registration of short-term object matches, 10 which allows to increase the reliability of the device operation.

Unit 11 produces a light indication of the state of objects on a special illuminated panel. Each state of the object corresponds to a certain kind of burning of the display element: it is lit continuously, does not light, or is lit by intermittent light.

The device provides for the implementation of two modes of monitoring the state of the object. In the first control mode, the display is carried out on a special scoreboard and transmitted to the centralized observation system, all without excluding information on the state of the objects. In the second control mode, the display and transmission of information about some states of the object is not performed. This allows for a certain period of time to focus the attention of the operator on the most important object states, excluding the secondary, losing ones from consideration. its meaning. The implementation of the two control modes is carried out using

5 address block 6, which is a set of two-way switches and a switch that allows switching sigals from the corresponding switches connected to

0 its inputs, on one output, depending on the address filed on its entry.

The synchronization unit 2 sequentially generates the address signals to the address inputs of the address5 block b. In accordance with the received address, the signal from the corresponding junction appears at the output of the address block 6; the shaper that is fed to the input of the shaper 10

0 resolution signal. If the signal corresponds to the first mode of control of the object, the shaper 10 of the enable signal outputs a signal to the display unit 11, which permits the census

5 without excluding information from memory block 9 in the memory cells of display unit 11. If the signal corresponds to the second mode of control of objects, the shaper 10 of the resolution signal, depending on the information recorded in memory block 9, either issues a permission signal to copy information from memory block 9 to display block 11, or disables this census. The control of the resolver signal generator is performed by the clocking pulses coming from the second output of the synchronization unit 2. The information output unit 12 permits the transmission of information via the communication link 14 to the central monitoring system and thereby concentrates monitoring of the state of many objects in one place. The information output unit is made on the triggers, the elements AND-NOT, the elements OR-NOT and amplifiers. When interrogating object devices, signals characterizing the state of an object are recorded in memory block 9, from where they are received in information output block 12. From the information output unit, signals on the state of objects on link 14 are transmitted to a centralized monitoring system. The information output unit 12 is connected to the address unit b, which makes it possible to exclude, in the second control mode, the transmission to the communication link 14 of that part of the information that has lost its value. The information output unit is controlled by the synchronization unit 2. Thus, the device for signaling, unlike the prototype, allows an increase in the number of monitored objects, fixing the short-term states of the objects and transmitting information to the centralized monitoring system.
