Description

The utility model relates to the field of electrical engineering, communications and telecommunications, in particular, to devices used in the diagnostics and setting of the radio signal parameters of the MultiCom MCRM-110D duplex transceiver radio station of the linear telemechanics system of the main gas pipeline (hereinafter referred to as MG).

Currently, work related to the diagnostics and tuning of the radio station [1] is carried out in laboratory or field conditions using the telemechanics module [2] and measuring equipment [3]. In the process of carrying out the work, the standard parameters are checked and adjusted, and the transceiver parameters of the radio station are adjusted. When using the existing method, measuring cables are used to check and control the electrical parameters of the radio station [4]. The tuning and verification process is always associated with the need to supply and receive reference signals between the radio station and the measuring equipment. At the same time, the time spent on assembly, tuning and control of the tested radio station is essential.

The disadvantages of this diagnostic and configuration method are:

- the possibility of erroneous connections when preparing for measurements;

- low reliability of connections between contacts of measuring cables and equipment;

- a laborious algorithm for setting up measuring instruments and a radio station, which can lead to equipment malfunction and prolonged downtime of the MG linear telemechanics system.

The task of the utility model is to optimize the diagnostics and tuning process of the MCRM-110D radio station.

The technical result is to reduce the time for diagnostics and tuning of the radio station due to the simultaneous connection of the equipment to the switching and diagnostic device.

The task is solved, and the technical result is achieved by creating a device consisting of a case, inside which there is a printed circuit board for switching connectors intended for connecting a telemechanics module, a radio station and a measuring device, while two LEDs are connected in parallel to the connectors, one of which is intended for signaling about supplying a reference signal from the measuring device to the input of the radio station, the second on receiving a response signal from the output of the radio station.

The schematic diagram of the device is shown in Fig. one.

A photograph of the claimed device is shown in FIG. 2.

The device 1 consists of a metal case, inside of which there is a printed circuit board for switching the connector (11), (12), (18), (19). Parallel to the connectors are connected two LEDs (13) and (15), one of which signals the supply of a reference signal from the measuring device (10) to the input of the radio station, the second on receipt of a response signal from the output of the radio station. Current limiting resistors (14) and (16) are connected in series with the LEDs. The built-in toggle switch (17) is designed to start the radio station transmitter. Connectors (18) and (19) are located on the top panel of the device (1) and are designed to connect a telemechanics module (6) and a radio station (5), connectors (11) and (12) are located on the sides of the device body (1) and are intended for connecting the measuring device (10) (radio communication service tester RST-430 or oscilloscope).

The device (1) operates as follows.

A radio communication service tester (10) is connected to the built-in connectors of the device (11) and (12) of the BNC-F type through the communication lines (cables) (2) and (3) and the tester connectors (8) and (9). The remote control module (6) is connected to the built-in connector (18) of the DB15F type through the connector (7), and to the built-in connector (19) of the DB15M type a radio station (5) is connected through the connector (4). The built-in toggle switch (17) manually starts the transmitter of the radio station (5). When this switch is turned on, the ground potential of the DB15M connector (19) is applied to the connector (4), as a result of which the transmitter stages receive a supply voltage, and the transmitter begins to generate a high-frequency signal, the frequency of which is determined by the interface circuit. The modulating generator from the radio communication radio tester (10) from the BNC-F connector (9) goes to the BNC-F connector (12) with a transition to the DB15M connector (19) for measuring and setting the transmitter parameters (5). To adjust the level of the transmission signal from the telemechanics module (6), the connector (8) of the DB15M type is connected in parallel with the connector (19) of the DB15F type. To measure and configure the parameters of the radio station receiver (5), the transmission signals of the connector (19) of the DB15M type are fed to the connector (12) of the BNC-F type. Connector (19) type DB15M is connected in parallel with connector (18) type DB15F for connection to telemechanics module (6). The glow of the diode (15) signals that a measuring device (10) is connected to the device (1), and the glow of the diode (13) signals the start of the transmitter of the radio station (5).
