To implement the RF control module has a radio receiver 433 MHz, and for GSM / GPRS connection – Built-in industrial phone. In addition, the module is GPRS-T3 jack for connecting an external microphone (Jack 3,5 mm), so that security of the GSM system can perform audioverifikatsiyu: after receiving a disturbing SMS-ku, the user can call a module number and listen to the protected object. To send control signals to the peripheral security equipment modules are equipped with two programmable relay outputs, such as NO. At the same time power connected to the GPRS-T3 security devices can be carried out through the AUX output of the module. The presence of the tamper wire entry allows for anti-tampering function, or program the alarm system GSM MICRA on another type of reaction.
And as an indicator of a problem connecting to the GSM network is a low-current output OC, which can also be used to indicate arm / disarm the system. MICRA modules will be installed only in enclosed areas with normal humidity, away from direct access by unauthorized persons and electrical appliances, which can cause interference with the functioning of the device. Also, when installing the module, you must consider that the thick walls and metal structures, "choke" the radio signal, so before you install the radio channel devices, for example, wireless alarms, security systems that use GSM, it is recommended use a special tester. To power the module requires a source of 220 VAC, but in case of power failure GPRS-T3 MICRA can use a battery backup power. Programming module can be perform locally with a PC using software GPRS-Soft, which is included in the package. For this module to be connected to COM-port using a special cable (part number DB9FC/RJ-KPL). Also, security of the GSM system can be programmed via GPRS-channel after entering the pre-prescribed in the module password.
In addition, the use of GPRS-technology allows you to transfer the event codes in the alarm system at the remote central monitoring STAM-2, or to convert SMET-256. New security modules Satel GPRS-T3 MICRA go on sale in November 2010. For more information on the security of GSM brand Satel, please e-mail or by telephone (495) 787-3342 to manager of sales "ARMO-Systems", which is the official Russian distributor of hardware and software Satel. The Polish company Satel is working on the global security market since 1990 and specializes in the manufacture and sale of equipment and software for burglar and fire alarm systems of various objects. Satel lets the receiving-control instruments OPS at 4, 8, 10, … , 128 areas, modules, security systems for GSM, light, sound, and combined detectors, burglar and fire sensors alarms, power supplies, kits, radio control, numerous accessories and other security components. By means of this company can manage and fine-tune the security and fire alarm systems on the networks Ethernet, Internet, through a modem or cell phone.
There are positional contour, combined and multi-cycle management. The design features. CNC machines have advanced technological capabilities of maintaining high feast nadezhnostin work. The design of CNC machine tools should tend to combine different types of obespeichivat processing (turning, milling, milling, grinding), easy loading blanks, unloading of parts (which is especially important when using industrial robots), automatic and remote upravleniesmenoy instrumental, etc. Povysheine precision machining is achieved by high precision and rigidity of the machine izgotovleinya exceeding the usual rigidity of the machine of the same destination, which produce a reduction in the length of its kinematic chains: primeniyayut pirvody autonomous, possibly reducing the number of mechanical gear drives of CNC machines must also provide a high bysrodeystvie. Increased accuracy helps eliminate gaps in the transmission gear drives innings snizheine friction losses in the guides and other mehainzmah, povysheine vibration resistance, thermal snizheine strain, with changes in machine sensors feedback. For umensheinya thermal deformation is necessary to ensure uniform temperature in rezim mehanzmah machine, which, for example, promotes preheating machine and its hydraulic system.
The temperature error of the machine can also be reduced by introducing a correction, a feed drive signals from temperature sensors. Basic components (frame, columns, bases) perform more zheestkimi by vvedeinya additional stiffeners. Guides CNC machines have a high wear resistance and low friction, thus reducing the Power steering servo drive, to increase the accuracy peremescheiny, reduce the mismatch in the tracking system. Pirvody and transducers for CNC machines. In connection with the development of microprocessor technology used for converters feed drives and main dvizheinya fully microprocessor-upravleinem digital converters and digital drives. Digital drives are electric motors operating at constant or alternating current.
Structurally, inverters, servo drives and the device main start and reverse yavlyayutsya individual electronic units upravleinya. Spindles CNC perform precise, rigid, with increased wear resistance of the necks, and posadochnyz based surfaces. The design of the spindle uslozhnyaetsyaiz much of it built in ustroystvavtomaticheskogo clenched and clamping tools, sensors for adaptive management and automated diagnostics. Supporting mehainzmy NC include tool changer, cleaning chips, lubrication system, clamping prisposobleinya, feeders, etc. This group mehainzmov CNC machines is significantly different from those mechanisms used in other universal machines. For example, the povysheinya productivity of CNC machines has been a sharp trailing uvelicheine of chips per unit time, hence creating vozinkla enobhodimost special devices for removal of chips. For time lost sokrascheinya feast downloads pisposobleniya used, allowing both set piece and take part during the processing of another piece. (Www.stankow.ru) Tool change (shops, avtooperetory, turrets) should ensure the minimum time required to change tools, high reliability, stability polozheinya tool, ie, size constancy departing polozheine axis with repeated changes of the tool, have the necessary capacity of the store or turret. Turret is the most simple tool changer: installation and tool clamping is done manually. In the working position of one of the spindle is rotated by the main drive of the machine. Turrets mounted on lathes, drilling machines, milling machines, multi-purpose CNC machines, fixed in the head from 4 to 12 instruments.
The broad scope defines a wide range of mineral products, manufactured by leading manufacturers, which include: – thermal insulation panels for metal, brick and concrete building components. Typically, they are pressed into between corresponding elements of design – mats for insulation and roof of underground structures. These products must be protected from moisture by installing […]
