Description

 The invention relates to techniques for automatic switching and transmission of measurement information, as well as to the notification technique and can be used to build information-measuring networks with emergency notification of subscribers about changes in the situation.

 Known systems for transmitting measurement information (in particular, about radioactive and environmental pollution), containing regional nodes of information accumulation, which are connected by lines of sensors, while the regional nodes are connected to the corresponding zone node, and the zone nodes are combined in a regional node, forming hierarchical structure (see Samkharadze TG The structure of the information-measuring network for the regions of radiation pollution and its hardware implementation. Instruments and control systems. 1994, N 9 p. 32-34 )

 However, to create a system requires significant costs associated with the construction of nodes and laying lines between them.

 At the same time, since there are telephone networks similar to the architecture of measurement information transmission systems, it is advisable to use telephone networks to transfer measurement information with a slight change in communication nodes.

 Known telephone communication networks contain switching devices (telephone exchanges) interconnected to which subscriber lines are connected.

 Known switching devices containing n switching units in the first link, n switching units in the second link, an additional switching unit and an information storage and output unit, connected accordingly (RF patent N 2041571, H 04 M 3/00, 1995).

 The known device reduces the amount of equipment compared to a three-link system and reduces the number of locks compared to a two-link system.

 In addition, privileged (priority) subscribers are provided with additional types of services - access to the data bank and non-blocking communication.

 However, when building a network for transmitting measurement information, all communications between the sensors and the information storage and output unit must be carried out through the nth switching unit of the first link, which can lead to a delay in data transmission. In addition, the device does not allow notifying personnel located in the zone where sensors are located about changes in the radiation or environmental situation.

 The technical result of the invention consists in the complete provision of locks during the transmission of measurement information when using telephone exchanges as regional nodes for accumulating and analyzing information, as well as in providing the possibility of notifying personnel working in critical locations of sensors.

 The indicated technical result is achieved by introducing into the switching and processing device measuring information and alerts containing n switching units of the first link, n switching units of the second link, the first additional switching unit and the storage and delivery unit of information, subscriber, service and outgoing sets, as well as the second additional a switching unit, a radio transmitting unit, and p receiving units (where p is the number of notified subscribers / personnel /).

 The drawing shows a functional electrical diagram of a device for switching and processing of measurement information and alerts.

The device for switching and processing measurement information and notifications contains in the first link n switching units 1 ₁ - 1 _n , in the second link n switching units 2 ₁ - 2 _n , the first additional switching unit 3, the storage and output unit 4, the second additional switching unit 5, subscriber kits 6, service kits 7, outgoing kits 8, radio transmitting unit 9, p receiving units 10 ₁ - 10 _p and measuring sensors 11.

The switching device and the processing of measurement information and alerts works as follows: a call to telephone subscribers through subscriber sets 6 is received at the switching unit of the first link 1 ₁ - 1 _n-1 . In the absence of direct connection (busy) with the switching units of the second link 2 ₁ - 2 _{n-1, the} connection is through the first additional switching unit 3.

Privileged (priority) subscribers are connected through the corresponding subscriber sets 5 to the nth switching unit of the first link 1 _n . These subscribers have the ability to write and read information from the storage and information delivery unit 4. In addition, these subscribers have virtually no locks, since there are additional links between the n-th switching units of the first and second links 1 _n and 2 _n . Measuring sensors through service kits 7 (m is the number of sensors equal to the number of inputs of the second additional switching unit 5) are connected to m inputs of the second additional switching unit 5. Since the number of inputs (ports) of the information storage unit 4 (computer) is limited and the control of most of the measuring sensors 11 should be intermittent, the introduction of a second additional switching unit 5 made it possible to agree on the number of measuring sensors 11 and the number of inputs of the storage and output unit 4.

 The second additional switching unit 5 can be made both in the form of a scanner, interrogating information sensors 11, and in the form of a switching unit that responds to a sensor (by the type of tube pickup in a telephone exchange). The data arriving at the k inputs of the storage and output unit 4 are processed and filled in this unit. After this, this information can be transmitted with or without a request to privileged subscribers, and also transmitted to the zone node through outgoing sets 8. Subscriber, service and outgoing sets are standard sets of any telephone exchange (in particular, electronic automatic telephone exchange).

 The maximum permissible parameters that can come from the measuring sensors 11 are also recorded in the information storage and delivery unit 4. The measuring sensors 11 are grouped into zones (for example, a zone inside the building, a zone outside the building). If from any of the measuring sensors 11 of the zone a signal is received that goes beyond the maximum permissible values, the information storage and output unit 4 generates a command to the radio transmitting unit 9, which at a frequency corresponding to this zone transmits to the receiving blocks 10 subscribers (personnel), located in this area of the danger signal.

 In the case of receiving blocks in the form of pagers simultaneously with a call signal, which is an alarm signal, information is transmitted that is reflected on the pager screen, allowing zone personnel to navigate the situation. At the same time, personnel in other areas do not receive alarms and continue to work. The receiving units of 10 subscribers can be permanently assigned to them, in this case, when changing the operating zone, the subscriber must give information to the information storage and processing unit 4, or be issued depending on the zone for every day.

 The device switching and processing of measuring information and alerts allows, thus, not only to process and transmit information, but also to alert personnel in emergency situations.
