Brief description of the drawings
In order to illustrate more clearly of technical scheme, embodiment will be described below needed for the accompanying drawing to be used
It is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, general for this area
For logical technical staff, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the pressing plate status checkout system that the present invention is provided.
Specific embodiment
To make structure of the invention and advantage clearer, structure of the invention is made further below in conjunction with accompanying drawing
Description.
Embodiment one
The invention provides pressing plate status checkout system, the cruising inspection system, including：
Platen sensor, the hub electrically connected with platen sensor, and it is connected to the host computer of hub output end；
Platen sensor is connected on pressing plate, and the output end of platen sensor is electrically connected with the input of hub, collection
After the state that platen sensor gets pressing plate is collected into, the state value that will be got is transmitted to host computer line device.
In force, the structure of pressing plate status checkout system is as shown in figure 1, including platen sensor 1, with platen sensor
The hub 2 of 1 electrical connection, and the host computer 3 for being connected to the output end of hub 2.Platen sensor 1 on pressing plate is obtained
The state value of the pressing plate is taken, state value is transmitted to hub 2, and transmitted to host computer 3 after hub 2 is concentrated.
Optionally, in the cruising inspection system, entered using monobus between the platen sensor 1 and the hub 2
Row data transfer.
The universal serial bus carried out data transmission between microcomputer conventional at present and peripheral hardware mainly have I2C buses, spi bus and
SCI buses.Wherein I2C buses are communicated (clock lines, a data line) in the line mode of synchronous serial 2, and spi bus are then
Communicated (clock lines, a data input line, a data output line) in the line mode of synchronous serial 3, and SCI buses
It is communicated in an asynchronous manner (a data input line, a data output line).These buses at least need two or two
Holding wire more than bar.
But monobus is different from above-mentioned bus, it uses single signal line, can not only transmit clock but also can transmit number
According to, and data transfer is two-way, thus this bus has circuit simple, hardware spending is few, with low cost, is easy to bus to expand
The advantages of opening up and safeguard, monobus is applied to single host system, can control one or more slave devices.
Ethernet is used between hub 2 and host computer 3 in the cruising inspection system, Ethernet is using band collision detection
Carrier frame listen multiple access mechanism.Ethernet interior joint is it can be seen that all information for sending in a network.
The course of work of Ethernet is as follows：
When a main frame in Ethernet will transmit data, it will be carried out as follows：
1st, whether there is signal on monitor channel in transmission.If any, show that channel is in busy condition, continue to prison
Listen, untill channel idle.
If the 2, not listening to any signal, data are just transmitted
3rd, continue to monitor when transmission, perform back off algorithm if finding to conflict, after waiting for a period of time at random, again
(when a collision occurs, being related to the computer of conflict to send can return to monitor channel state to perform step 1.
4th, sent successfully if conflict is not found, all computers are before attempting to send data again, it is necessary to most
9.6 microseconds (being run with 10Mbps) are waited after nearly once transmission.
Compared with other kinds of network, Ethernet exist be widely used, traffic rate is high, resource sharing capability is strong, can
The advantage such as sustainable potential is big.
In addition, for the ease of being observed to patrolling and examining result, being provided with host computer for showing the aobvious of pressing plate state
Show equipment.
In order to realize the monitoring to pressing plate state, infrared emission part, infrared emission part are provided with platen sensor
Launch infrared ray to pressing plate, the state that pressing plate is presently in is determined according to ultrared reflection case.
In actual use, the state of pressing plate includes throwing state and moves back state.Based on the pressing plate sensing for proposing above
The operation principle of device 1, specific status monitoring process is：
Optionally, the platen sensor, is used for：
When the state of the pressing plate is throwing state, the infrared ray that infrared emission part sends moves back part by the throwing in pressing plate
Reflection, now platen sensor generation represents the signal value of throwing state, and transmits to control chip.
Optionally, the platen sensor, is used for：
When the state of the pressing plate is to move back state, the infrared ray that infrared emission part sends does not move back portion by the throwing in pressing plate
Part reflects, and now platen sensor generation represents the signal value of state of moving back, and transmits to control chip.
The invention provides the pressing plate status checkout system for obtaining pressing plate state, including platen sensor, sensed with pressing plate
The hub of device electrical connection, and the host computer for being connected to hub output end；Platen sensor is connected on pressing plate, pressing plate
The output end of sensor is electrically connected with the input of hub, and hub gets the state of pressing plate platen sensor is collected into
Afterwards, the state value that will be got is transmitted to host computer.Platen sensor is installed by beside each pressing plate, using infrared external reflection
Principle gathers the status information of each pressing plate, and by Ethernet, host computer will be delivered on pressing plate status signal, on host computer
Pressing plate state is patrolled and examined.Patrol and examine, patrolled and examined in reduction so that staff need not be sent and go to pressing plate location to carry out pressing plate
Also improved while workload and patrol and examine efficiency and accuracy rate.
