Two, system principle introduction:
1, the high precision temperature acquisition system hardware is described
1), collecting part
With the AT89S52 single-chip microcomputer is core, external house dog X5045 and a slice 11.0592MHZ crystal oscillator constitute minimum Single Chip Microcomputer (SCM) system, the I/O mouth of using the AT89S52 single-chip microcomputer has the function of bi-directional transfer of data, P3.4 is connected with the DS18B20 one-wire bus, realization is read and write operation DS18B20, add a pull-up resistor on bus, this resistance can change resistance according to what and the length of gathering distance that add network DS18B20.Utilize the definition of P3.0 and P3.1 specific function I/O mouth, as the transceiver of communication.What P2.0 used AMD2483 enables to control pin.Here we have used the TQFP encapsulation of AT89S52, and volume is little, and for wiring board has been saved the space, we use the design of JTAG standard emulation interface thus, and are the same with all microprocessors, by jtag interface program are downloaded in the AT89S52 chip.Realize operating function.Collecting part schematic diagram such as Fig. 2.
2), power unit
When carrying out system's operation, indispensable is exactly the stability and the reliability of power supply, and AMS1117-5.0 has current limliting and the overheated defencive function that automatically shuts down, and its built-in band-gap reference can guarantee the error precision of output voltage.Output terminal need connect one at least the tantalum electrochemical capacitor of 10uf be used to improve the transient response and the stability of output terminal.Be mainly the power supply of single-chip microcomputer and peripheral circuits.The a of B0505S-W5 Jin Shengyang company production designs at needing to produce one group of application scenario with the power supply of input isolated from power in the distributed power supply system on the wiring board specially, and here the ADM2483 for internal insulation provides insulating power supply and MAX488 communication that insulating power supply is provided.Thereby make the transmission of signal more reliable.
3), 485 communication parts
The ADM2483 that we adopt is a serial RS485 interface chip that ADI company produces, and adopts dual power supply, and the RS485 chip that output and input are isolated fully can be strengthened acceptance and transmission to useful signal, has increased the reliability of telecommunication.The function of the timer of cooperation 555, EA_485 is in the low level accepting state under normal conditions, enables EA_485 and become high level when TXD_IN has signal output, and data are sent.EA_485 gets back to the low level accepting state automatically when distributing this segment data, sends data during this period of time by the R5*C5 decision, integrality that can the specified data transmission.The LED3 indication information sends indication.The transmission course of monitoring information intuitively.
4), 422 communication parts
Host computer is by A, B end input command, and this is a RS422 receiver port, and Y, Z receive order, and this is the transmitter port of RS422.Realized the communication mechanism of full duplex.Adopt the mode of light-coupled isolation at the other end of RS422,, increased the accuracy and the anti-interference of information transmission, guaranteed information integrity power supply and Signal Spacing.In conjunction with Fig. 5,6N137 light-coupled isolation chip U8 is as receiving information isolation.Resistance R 12, R13 are respectively the pull-up resistor of received signal bus, and LED0 is the received signal pilot lamp; 6N137 light-coupled isolation chip U7 is as sending information isolation.Resistance R 16, R18 send the pull-up resistor on the bus respectively, and LED1 is for sending signal lamp, the transmission course of monitoring information intuitively.
2, the high precision temperature acquisition system software is described
In the duplex high precision temp measuring system, temperature measuring unit can independently be carried out the data communication of data acquisition and host computer, send the temperature data that measures to host computer (main frame), receive host computer and send steering order, transmit data, adopt the CDT code command of fixed length with the instruction of upper machine communication, and have the CRC error correction correctly to transmit to guarantee data.
In the multipoint temperature measuring system, advantage such as the system architecture that 1-wire digital temperature sensor (for example DS18X20) is little because of its volume, constitute is simple is used more and more widely.64 unique bit sequence number are all arranged in each digital temperature sensor, and (minimum 8 is product code, thereafter 48 is device serial number, last 8 is preceding 56 cyclic redundancy check (CRC) code), just may operate on it after having only this sequence number of acquisition, also could in multisensor syste, they be discerned one by one.In conjunction with software flow pattern Fig. 6, because minimum 8 of sensor sequence number be the product code name, " place values of needs " can provide by the value of correspondence, and key is the identification of 48 device serial number thereafter.Here adopted the ordering thought of " complete binary tree ", as shown in Figure 7.Concrete thinking: be located at the K position data bit conflict takes place first, at this moment all sensors are divided into two classes, and promptly this is 1 sensor and is 0 sensor." need place values " gives 1, and the K position is that 1 sensor still is articulated on the bus.If next the data bit conflict takes place for K+M, K+N position, " place value that needs " still gives 1 respectively, obtains a sequence number.Next process still gives 1 in K, K+M position " place value that needs ", but then gives 0 in the K+N position, obtains the sequence number of another sensor.The 3rd process still gives 1 in the K position, and gives 0 in the K+M position, continues identification on this branch road.The K position is after the sequence number of 1 sensor has been discerned, and when getting back to the K position, " place values that need " give 0, discerns the sensor sequence number of this branch road in the same way.By this thinking, the sequence number of a plurality of sensors only needs to discern once respectively.
Behind the opening relationships table, weave program, system can put into operation.When reading the temperature of each point for measuring temperature, need use " meeting " ROM order, this order request takes out the sequence number in the relation table and delivers on the bus, and the sensor that has only sequence number to conform to it just is articulated on the bus, can read its temperature.
In sum, with simple hardware and the automatic opening relationships table of programmed method, in unibus multipoint temperature measuring system, realized the automatic identification of digital temperature sensor, help debugging, the maintenance of system greatly, reduce maintenance workload, and solved maintenance work in the past and must finish, rather than the inconvenience of finishing by the operations staff by the professional.
