FIG. 1 shows a block diagram of the proposed device; in fig. 2 is a schematic diagram of a control unit; in fig. 3 is a schematic diagram of the block analysis of beds; in fig. 4 is a schematic diagram of the address descrambler and counting unit. The device (Fig. 1) contains: central point .1, address decoder 2, board 3, recording unit 4, monitored objects 5, information fixing blocks b, counting unit 7, control unit 8, bed occupancy analysis unit 9, task block patient code 10, key block 11, and shift register 12. The control block (Fig. 2) contains AND elements 13, generator 14, memory element 15, and delay elements 16-19. The bed occupancy analysis block contains (FIG. 3) the OR element 20, the inverter 21, the AND elements 22-25, the memory element 26 and the delay element 27. The address decoder (Fig. 4). contains n series-connected cells 28, each of which consists of an element 29 and a driver 30, an element 31, a counter 32 and an inverter 33; the counting block contains a counter 34, a decoder 35-. The device works as follows. at once. Controlled objects are set up near the patient's beds in the wards of the hospital and are intended for fixing on them some medical information and transferring them for subsequent registration and processing. Upon admission of the patient in the emergency department of the hospital in the case of: 7 and with the number of the patient’s history, the patient is given a block of patient code 10 (indexer), which is then inserted into a special slot 36 on the front panel of the monitored object 5. When bypassing the patients, the attending physician in the fixation unit Information 6 Records patient data by setting a certain switch position. The device is started by applying a pulse to the triggering input 37 manually or automatically according to a certain program. This pulse sets the counting block 7 on O, address decoder 2, memory elements 26 and 15 in the bed occupancy analysis index 9 and control unit 8 and all the shift registers 12 monitored objects 5 through a certain bus 38 of the communication line 39. The same impulse, proy. The delay element 16 records 1 through a certain bus 40 of the communication line 39 in the first discharge of the shift register 12 of the first controlled object 5, as a result of which the output of this discharge produces a voltage that is applied to the first current key of the key block 11. From the output, the voltage is fed to the control bus 41 and to the unit for setting the patient's code 10 and through certain contacts of this unit and a special socket 36 to the information buses 42 of the communication line 39. The voltage from the information 42 and the control 41 buses over the communication line 39 served on ne The first inputs of elements And 13 in the control unit 8. The triggering pulse through the delay elements 16 and 17 is applied to the second inputs of elements And 13, as a result of which those elements And 13 are opened, the first inputs of which came from the information bus 4 and the control 41 As a result, a corresponding recording is made on the punched tape in the recording unit 4. The triggering pulse through serially connected delay elements 16, 17, 19 is fed to the input transporting the tape of the recording unit 4, causing the punched tape to move one line. A start pulse through successively connected delay elements 16, 17, 18 is also fed to the input of element 15. Tilting, element 15 starts a generator 14, which begins to generate synchronizing pulses, which arrive on the corresponding bus 43 of communication line 39 to all shift registers 12 of controlled objects 5. Using synchronizing pulses from generator 14, the shift register 12 and key block 11 are alternately fed to the block for setting the patient code 10 and fixing blocks for information 6 and then to inform 42 and control 41 lines of communication 39. The voltage on the communication line 39 is supplied to the first inputs of the elements AND 1 to the second inputs of which the corresponding synchronizing impulses from the generator 14 are supplied. The elements AND 13 open, and alternating occurs in the recording unit 4 recording information from the patient setting code block 10 and information fixing blocks 6. After reading the information from the first monitored object 5, the pulse from the output of the shift register 12 to the bus 44 of the communication line 39 is fed to the input of record 1 of the first bit p Giustra 12 next shift controlled object 5. Next, reading of information from all subsequent objects are controlled similarly to the above. From the last bit of the shift register 12 of the last monitored object, the voltage (1) is applied to a specific bus 45 of the communication link 39 to the trigger 15 of the control unit 8, which returns to its initial state, and the generator 14 stops generating the clock pulses, and this ends. the process of interviewing controlled objects and recording information on a punched tape of a registering unit 4. As a result of polling controlled objects on a punched tape, we get punched four lines each, referring to one object. The first two lines (8 bits each) contain punctures of the control tire 41 (1 bit) and the case history numbers from the patient task code block 10 (7 bits), the second two lines (7 bits each) correspond to the information, z.fixed in the block of information fixing 6. In the case of a free bed on a punched tape, in the first two lines (out of four relating to one object) only punctures of the control tire 41 will be present. Information from the control 41 and informational 42 tires is also fed to the block analysis of the occupancy of the beds 9 which is intended for av the automatic output of the pulse at the time of the survey in the case when an object is being polled in which there is no patient code setting block 10 - the bed is free. This unit works as follows. The voltage from the information bus 42 is applied simultaneously to the seven-input element OR 20, at the output of which a voltage appears, if there is a voltage on at least one information bus. This voltage is applied to the input of the inverter 21 and after inversion to the element 22, to the second input of which voltage is supplied from the reference bus 41 of the communication line 39. In the above described case, although 5y there is a voltage on one data bus OR 20 voltage (1) also appears, at the output of the inverter 21 in this Case there is no voltage (O) and, therefore, at the output of the element And 22 there is no voltage. Thus, when the bed is occupied by patients, when interrogating objects on information tires 42 of communication line 39 there is a voltage, therefore, there is no voltage at the output of the occupancy analysis block 9, which indicates that the bed is occupied. In the case of a survey of a monitored object in which there is no block for setting the patient's code 10, which means that the bed is not occupied, there is no stress on the information buses 42 during the transfer of the disease history number. Only the control bus 41 is under voltage. In this case, there is no voltage at the input and output of the OR element 20. Then the voltage appears at the output of the inverter 21 and the element 22 opens upon arrival at its second input of the first signal from the control bus 41 of the communication line 39 This voltage is applied to the first input of the element 23, to the second input of which a signal is output from the element 26, and the output of the element AND 23 is the voltage that is delayed by the delay element 27 for the time required for the second pulse to arrive from the control bus 41 to the input of the element 22 and the element 26. Upon the arrival of the second signal from the control bus 41 trigger 26 rolls over with an element 24 and a voltage is applied to the second input of element 25, the first input of which by this time has already been applied to voltage from delay element 27. And element 25 opens, and a voltage pulse appears at its output 46 wives, testifying to the availability of free Coy Ki. Consequently, if the bed is free, there is no voltage on the information busses 42 during the transmission of the case history number (on the control bus 41, the voltage appears as two sync pulses go to the first and second inputs of the shift register of the monitored object), at block 46 analysis of the occupancy of beds 9, a voltage pulse appears, indicating the presence of a free berth. This voltage pulse is applied to address decoder 2. From output 47 of element 26 of block occupancy analysis block 9, a pulse is sent from element 29 of address decoder 2 to each cell 28, the quantities of which are equal to the number of departments in the hospital. The signal from the output of the element 29 of the first cell is fed to the counter 32. The feedback logic allows the generator 30 and the inverter 33 to count the number of beds to a certain number equal to the number of places in the corresponding hospital department. If in the process of polling the objectsNbJX control unit from the bed occupancy analysis unit 9, a pulse arrives at the input 46 of the address decoder 2, corresponding to the presence of a free bunk, this pulse is fed to the second input element and 31, to the first input of which inverter 33 . Element And 31 opens, and the pulse arrives at the counter 34 of the counting unit 7, which counts the number of these pulses, corresponding to the number of free beds in the first compartment. Thus, if during the period of time when the counter 32 counts the number of the monitored controlled objects 5 of the first compartment, from the block of analysis of the beds 9, there are pulses indicating the presence of free beds, then the counter 34 of the counting block 7 will count the number of free beds in this branch. When the counter 32 counts up to a certain number equal to the number of beds in the hospital ward, a voltage appears at the output of the shaper 30, which closes And 29 and 31 elements through the inverter 33. The same voltage is applied to the And 29 cell of the second cell 28, and the counter 32 is turned on, producing a similar count of pulses coming through the bus 47 for the next hospital unit. In the course of operation of the counter 32, the counter 34 counts the number of pulses arriving on the bus 46 from the bed occupancy analysis unit 9, the number of which corresponds to the number of free beds in this department of the hospital. The circuit solution of the second and subsequent (except the last) cells differs from the first introduction of the three-input element 29 and the connection of the second output of the element 29 to the input of the counter 34 of the counting unit 7. The last cell performing the same functions as the previous ones is simplified, since here there is no need for a counter 32, and only the counting of free beds in this unit is carried out. Element I 31 at the first entrance is open from the moment when the counter of the penultimate cell has finished its work. At the second input, element 31 will open. C at the moment it enters the bus 46 from the block for analysis of the occupancy of the 9 beds, indicating the presence of a free bed, and the counter 34 of the counting unit 7 will count these pulses corresponding to the number of free beds in the last compartment. Using the decoders 35, the counting results are displayed on the scoreboard. The economic efficiency of using this device is determined by its technical advantages indicated above.
