Critical Wireless

Managing the factory of services with the system SatNetwork the SAT the factories on watch technical frequently are seen it jeopardize in superfluous tasks that complican the work and are delaying the tasks more and more. As the factory grows and the level of repairs is greater becomes impossible to take an order without a quality tool allows that it. With the SAT system of SatNetwork (www.satnetwork.com.ar) it is possible to load spare parts in the stock, to realise movements, to enter replacements of components, to assign the models in which the same are used, to look for parts by different concepts (code, description, model, application, etc.), to sell spare parts, to organize the stock of repair manuals, to valorize stock and to revalue increasing it the values by a coefficient, to load new distributors of spare parts with its respective costs, to control several deposits at the same time, to request spare parts for a service or stock. As far as the service area it will be able: to enter repair orders, to handle to direct services and guarantees of different companies, to realise reimbursements, to accept reclamations, to enter the accessories that are given with the equipment, to agendar appointments for domiciliary visits, to arm the trip tickets of the technicians of addresses, to add notes with information for factory (the same will be presented/displayed the technician whenever it consults a repair), to control the present state of the repairs, to budget, to take sign and to invoice the service, to assign the pending tasks, you order to print them of repair and delivery of the equipment, to look for a repair by different concepts (number of order on watch, client, telephone, movable telephone, direction, series of the equipment, model, number of guarantee, factory code). The control on the clients will be total, being able to agendar them and to look for them according to name, address, locality or telephone, to handle accounts for special clients, to send mail' automatically; s or sms s with the present state of the equipment, to send to the great clients an email with the pending repairs by budget, to notify to the same the aim of the repair, to arm remitos and to invoice repairs by groups, to allow the clients to consult the state of its equipment through Internet. Other characteristics of the system will make the task of the administration of the much more dynamic company. Between these characteristics they stand out: daily box, monthly report of repairs, customized listings, agenda of contacts, personalisation of the legal data of the company, personalisation of type of currency and tributary situations according to the country, 350 different statistical graphs, generation of administrative reports (teams, commissions of the technicians, hours worked by the employees, states of all the repairs in factory), to create accounts of users of the system to limit its access the same, complete management of profiles of users, to enter technical and new factories the staff. The constant development of this application assures to always have the latest in technology, SatNetwork sends periodically last information referring to the updates of the product that are leaving. Also it is possible to accede to the site and to internalise themselves of the last advances in the system and to obtain evaluative versions before deciding the purchase.

Another mode of transmission is that the command is passed on regular wire car by a weak signal, similar to the interference from the spark plugs. The advantages of this method is that no wires are not connected directly to the alarm system and the output relay, hence the name of the relay – 'Wireless'. It can be hidden in a bundle of regular wires, find and neutralize it is practically impossible. But this method requires more security team itself – theoretically it can 'eavesdrop' and write any wire a car, so the commands must be encrypted variable code. The third way to – on the radio.

The security system is equipped with a transmitter, and the output relay – receiver. This method advantages of wireless relay continues, but has some limitations related to the fact that getting the team to allow the engine may be difficult because of interference. Situational relay may be possible to to determine what is blocking relay circuit, the absence of any signal or even the diagnostic reports a car. To prevent this, the digital relays are becoming more complex, and are ability to decide when they lockable chain must be restored, and when – no. For example, the relay can simulate engine failure, while taking into account what sort of circuit blocks it, and install the degree of 'seriousness' fault. This approach to the blocking of the engine is possible only if the security system of communication between its modules and actuators. Class channel management The most common and convenient control channel security system is to control the radio, using the remote control.

Long time digital relays have been effective in blocking – the relay will not work until the receive the command. A security system sends this command only at a resolution of a trip, and not when the car lights flashing and siren screaming hysterically. But what prevents hijacker bring security system, similar installed on the vehicle by connecting it to the cigarette lighter, to simulate the disarming? To protect against this in the management team include the serial number. Number does not match – the relay is not activated. Constant and variable code there Another danger: as long as relay itself is able to recognize a digital command, so you can make a device that just detects such a command, and then, if necessary, will even be able to repeat it. Kinda recorder.

If the command to restore a locked chain every time the same, then the thief can reproduce it with a tape recorder. To protect against such attacks, the command code make the variables every time new play already 'spent' code does not result in resolution of the engine. How to pass command to the digital switch? 'Wireless' control relay or the wire (data bus)? You can connect the alarm system and digital relay wire, as was the case with analog control, and pass on the wire team. Such control is called managed by a dedicated wire or bus. Its advantages include good Immunity and the complexity of connecting 'the tape'. The disadvantage – the fact that the output relay can be found by tracing where he goes wire management.
