Abstract
The utility model relates to a novel photoelectric data transmission device which is widely suitable for the information transmission between a stacker carrying out the online operation in the automatic warehousing system and a ground monitoring machine. The utility model is characterized in that the utility model is composed of a correlation type photoelectric switch (1) on a ground control machine (A), a programmable controller (2), a correlation type photoelectric switch on a moving machine (B), and a programmable controller. Two pairs of common correlation type photoelectric switches can replace an expensive infrared communication device, which can reduce the cost of the equipment. Because a special communication module is omitted in the device, the utility model has simple structure and the utility model can enhance the reliability. The utility model is also suitable for the information transmission between other straight-line running moving machines and other ground controlling machines.
Description
The utility model relates to a kind of novel photoelectric data transmission device, and this photooptical data transmitting device is widely used in the piler of on-line execute in the warehousing system and the information transmission between the ground monitoring machine.
The piler of Automatic Warehouse generally is the mechanically moving of depositing/put goods automatically by programmable controller controls, for the piler of the warehousing system on-line execute of being monitored and being managed by ground-based computer and the information transmission between the ground monitoring machine is indispensable, past method commonly used is to adopt cable and these the two kinds of methods of trolley of hanging, technical all relatively backward, especially when the piler travelling speed is higher, reliability of information transmission is lower.
In recent years, developed country adopts infrared communications set to replace lead (flexible cable or trolley) to come transmission information, the Infrared Wireless Communication mode is not subjected to the influence of piler travelling speed, the interference free performance height, transmission range can reach 200m, because these technical obvious superiority, the Infrared Transmission mode is promoted the use of in the Automatic Warehouse abroad.But at home, still can not produce this infrared communications set voluntarily at present.As from external import, 30,000 yuan of every cover price Renminbi add communication module and additional device, and every piler need spend about 40,000 yuan.With one the medium-sized Automatic Warehouse in 5 tunnels being arranged is example, and only the investment of 1 of piler on-line communication just reaches 200,000 yuan, and so high investment is difficult to accept to domestic general user at present.
The purpose of this utility model is to adopt the novel photoelectric data transmission device to substitute import infrared communication transmitting device, reduces equipment cost greatly; Go back simplified structure simultaneously, improved reliability.
The utility model is to realize like this, a kind of novel photoelectric data transmission device is characterized in that: mainly go up correlation optoelectronic switch 3 by Ground Control machine (A), programmable controller and mobile machine (B) are gone up the correlation optoelectronic switch, programmable controller is formed, input/output point DI/DO on the described programmable controller 2, by a pair of emission/reception Gf/Gj, link to each other with the output/input point DO/DI of the programmable controller 4 of symmetry respectively.
Accompanying drawing 1, the novel photoelectric data transmission device constitutes,
Accompanying drawing 2, data transmission flow process figure.
The novel photoelectric data transmission device is gone up correlation optoelectronic switch 1 by ground monitoring machine (A) as shown in Figure 1, the correlation optoelectronic switch 3 on programmable controller 2 and the piler (B), and programmable controller 4 is formed.The emitting head of this device by two pairs of correlation optoelectronic switches 1,3 with the electric impulse signal of the digital quantity output point on the programmable controller 2,4 convert light pulse signal to, the reception head counter-rotating by correlation optoelectronic switch 1,3 changes electric impulse signal into again, send the digital quantity input point of programmable controller 2,4 to, this goes out signal, to realize the wireless messages transmission between ground monitoring machine (A) and the piler (B).
Because it is less that piler (B) is gone up the data volume of information transmission between programmable controller and the ground monitoring machine programmable controller, general compressible is two bytes, not high to the rate request that transmits simultaneously, utilize these two characteristics, these devices to adopt common correlation optoelectronic switch, use on the piler and digital input/output point (DI/DO) point of programmable controller 2,4 and the information transmission that corresponding program realizes 2,4 of two programmable controllers on the ground monitoring machine.
The implementing procedure of data transmission is seen shown in the accompanying drawing 2, the emitting head Gf of optoelectronic switch 1 is connected on the DO point of ground monitoring machine programmable controller 2, utilize program to make this output point " flicker " according to certain rules, a reception receipts Gj who is contained on the last optoelectronic switch 3 of piler (B) aims at all the time with the emitting head Gf of the optoelectronic switch 1 of ground monitoring machine (A), when ground monitoring equipment emitting head Gf " flicker ", reception on a piler Gj just receives a string light pulse, and convert thereof into corresponding electric pulse string, go up DI point input on the programmable controller 4 and the rule of reading the electric pulse string with program by piler B simultaneously.Last two programmable controllers 2 of ground machine A and piler B, the conversion of data and train of impulses and inverse transformation adopt " pulsewidth " mode between 4, promptly with wide/narrow 1/0 of the binary number of representing of pulse, with 4 bits " 0110 " is example, be train of impulses after being transformed to electrical information, be that pulse train is " narrow-wide-wide-narrow ", the effect of photoelectric sensor emitting head Gf is that the electric pulse string is become optical pulse train, with the wireless transmission between realizing on ground and the machine, the reception head changes the optical pulse train that receives into the electric pulse string again is convenient to programmable controller energy sense data.Information transmission between ground monitoring machine A and the piler B is two-way, promptly the programmable controller on the piler earthward monitoring equipment to transmit the flow process of information same as described above.Be to realize by other a pair of photoelectric sensor and other DI/DO point.
The utility model has the advantages that, replace expensive infrared communication with two pairs of common correlation optoelectronic switches Device greatly reduces equipment cost, in the device owing to saved the private communication module, thereby the structure of making Simply, Reliability Enhancement, the utility model are equally applicable to moving machine and the ground control of other linear runnings Communication between the machine processed.
