Abstract
The invention provides a wireless connection control device for a passive contact point. The device is characterized by comprising a transmitter internally provided with an SIM (Subscriber Identity Module) card and a receiving processor internally provided with an MSC (Mobile Switching Center) receiving module. The wireless connection control device has the following effects: firstly, the connection has small possibility of staggering in wired connection; secondly, the connection is not restricted by environment and space, or is not conflicted with the other circuit or device during paving or installation; thirdly, corona discharge, skin effect, proximity effect and electromagnetic interference existing in system cable in wireless connection influences the electric signal transmission; fourthly, the device is simple to mount, easy and convenient to maintain; and fifthly, the device is beneficial for integrated development of electric control, and is capable of forming a completely new integrated automatic control system. The device can be used for quickly developed industrial computers; simultaneously, the device also can be involved in frequency converter and soft starter system.
Description
Technical field: the present invention relates in a kind of electric wiring to connect and the device of control particularly a kind of wireless connection control device that does not have source contact.
Background technology: in the automated production circuit of existing all trades and professions, various no source contacts are as travel switch, optoelectronic switch, near switch, foot-switch, rotary switch, temperature switch, level switch; Pull switch, the various buttons of sideslip switch, the output of various sensors, the output of tongue tube etc., these no source contacts all pass through to adopt the connection of non-ferrous metal lead mostly.In use there is following deficiency in the wired connection mode of the no source contact of this kind: 1, wiring quantity is big, and is complicated, loaded down with trivial details, occurs connecting the mistake of dislocation easily; 2, line is damaged easily, because line all can only be spread with condition restriction mostly on the spot, is difficult to accomplish safeguard measure safe against all possibilities, at operation field since personnel walk about and the factors such as collision of external force are easy to line is damaged; 3, very difficult during being equipped with of line, for example run into rugged environments such as great river, river, cliffy summit, high temperature corrosion, and have the terminal loose contact root of accident often.The laying of line not only has very big difficulty but also lays with high costs; 4, line exists corona discharge, kelvin effect in system cable, and drawbacks such as approach effect, electromagnetic interference (EMI) influence the conveying of electric signal; 5, line is laid needs the place, can occur clashing with the laying or the installation of other circuit or equipment.
Summary of the invention: the objective of the invention is to, at the existing existing deficiency of various no source contact wired connections, and a kind of wireless connection control device that does not have source contact is proposed, it makes the connection of no source contact need not lead, is not subjected to the restriction of environmental baseline, can not clash, can not occur the mistake that poor wire connection is connected dislocation with the laying or the installation of other circuit or equipment.
Can realize the object of the invention by following technical proposals, a kind of wireless connection control device that does not have source contact is characterized in that, it is made of the transmitter of a built-in SIM card and the receiving processor of a built-in MSC receiver module.
The transmitter of built-in SIM card by no source contact, digital signal amplification module, carrier oscillator, modulator, radio frequency amplifier, SIM, power supply through being electrically connected to form.
Built-in SIM card is more than one in the transmitter.
The receiving processor of built-in MSC receiver module by MSC receiver module, industrial computer, passive contact point signal reductor, power supply through being electrically connected to form.
Passive contact point signal reductor is made up of through being electrically connected plural relay, and the number of relay is corresponding with the number of built-in SIM card in the transmitter.
Be to save the resource of SIM card, SIM card can corresponding no source contact more than two, connects with lead between the no source contact.
Effect of the present invention is: the problem that 1, is not easy to occur ease of connection dislocation in the wired connection, because there are not the wireless connections between source contact and the electrical control gear, it is the corresponding wireless transmit frequency of a SIM card, after a SIM card and a place do not have source contact and determine relation, their only corresponding wireless transmit frequencies, the wireless transmit frequency that different SIM card is corresponding different is so be not easy to occur the problem of ease of connection dislocation; 2, its connection is not subjected to the restriction in environment and space, existing line is damaged easily in the no wired connection, the laying of line is subjected to the very difficult sometimes problem of environmental constraints, the problem that laying or installation with other circuit or equipment clash also can not occur; 3, in the no wired connection in system cable existing joint contact resistance, corona discharge, kelvin effect, approach effect, electromagnetic interference (EMI) etc. influence the drawback that electric signal is carried, since every corresponding wireless transmit frequency of SIM card, no any interference and influence between each wireless transmit frequency; 4, install simply, maintenance is easy and convenient.5, no source contact transmitter can be changed arbitrarily and exchange, but SIM card is unique corresponding relation.6, be beneficial to the integrated development of electrical control, because it is a kind of total digitalization, wireless receiving and dispatching, the electrical control of " fully integrated automated communication mode ", thus realized with wireless replacement wired, it is the electrical control in the wireless connections wire circuit, a kind of brand-new integrated automation hierarchy of control of light current control forceful electric power, it can be with the industrial computer that develops rapidly, and PLC integrates with, simultaneously also can participate in frequency converter, in the soft initiator system.
