Light beam is bright, and other light beams do not work, and display location is exchanged after 5 seconds duration, and the 2nd, 4,6 ... 24 position light beams are bright, other light beams
Do not work, 5 seconds duration, then rod position indication box recover normal operating conditions automatically.
2) driving plate
With upper and lower limit treatment and RS485 signal isolation process circuits in each driving plate 5, by signal input plate 3
The RS485 signals and upper and lower limit signal for being transmitted need to be processed using Phototube Coupling, that is, RS485 signals and the upper and lower limit letter being input into
Number first have to by isolation processing, protect the circuit and whole system case of rear end.
The operation principle of driving plate 5 is generally：Rod position and upper and lower limit number that the collection signal input of driving plate 5 plate 3 is transmitted
According to using quilt after Phototube Coupling treatment, be input to MCU (data processor) carries out Treatment Analysis to these signals, and MCU is to reading
RS485 signals are parsed and main frame carried out accordingly, the data of reception processed through MCU after most at last display command be sent to it is aobvious
Show drive circuit, drive LED array of display to light by display driver circuit.
Driving plate 5 also receives the self-test signal of outside, and after self-inspection button 35 is pressed, rod position instruction device enters self-inspection shape
State, after the completion of self-inspection, rod position instruction device recovers normal operating conditions.
3) display board
Display board is the display unit 22 in aforementioned structure description section, and it mainly includes the installation in structure description part
Plate 221, the installing plate 221 is used to install 223,118 position indicators of bar shaped of upper limit indicator lamp 222 and lower limit indicator lamp
224, aforesaid plurality of indicator lamp is generally electrically connected by wire with driving plate 5, and the working condition of this multiple indicator lamp is by driving plate 5
It is controlled, display unit only has display luminous function.

View.Data transmission format as shown in appendix 1, the list data of subordinate list 1 be hexadecimal, each frame include tributary address, function code,
Register address, register value (data) and CRC check code totally 8 bytes.
The transmission means of each byte is as follows：
Start bit：1, low level；
Data bit：8；
Check bit：1, even parity check；
Stop position：1, high level.
Tributary address is defined：Each rod position display unit sets a unique address.The hexadecimal of tributary address is compiled
Code is seen below shown in subordinate list 2.
Rod level display apparatus of the present utility model need to carry out response after detection data is completely received to rear portion host computer system
Response.Normal response is that the data for receiving are replicated.Subordinate list 3 lists the example of normal request and response.
The position instruction form of rod position instruction device is easily described referring to Figure 10.
As shown in Figure 10, it is 118 that the rod position of every indicating bar 2 indicates total spot number, and each luminous point represents 100mm, makes
The length of control rod is represented with 111 continuous luminous points；The light beam constituted with the luminous point of continuous luminous is simulated and indicates control rod in heap
Length and position in core active region, the part light that control rod is inserted in reactor core active region are lighted, and propose the part light of active region
Point does not light, and the display length of light beam represents the control rod length being inserted in reactor core active region, and the lower end of light beam indicates control rod
Position.
After the display data of rod position is collected, being shown as of position indicator 224 shows from bottom to top, i.e., emitting led
The bottom of unit represents the bottom of control rod, the not emitting led position for representing control rod bottom of first be connected with its bottom,
Namely at the reading of position.The position stroke of whole control rod is 118 luminous points, and the length of control rod is 111 luminous points, when
When the position of control rod is more than 7 luminous point (700mm), the light beam of indicating bar can be reduced accordingly, when position is 118 luminous points
When, then the light beam of whole indicating bar will be removed, and the position indicator of the indicating bar is the state not worked.
The workflow of rod position instruction device is easily described referring to Figure 11.
Step 1, electricity is initialized first in the instruction device of rod position, sets the original state of internal register；
Step 2, calls self-check program, subsequently into main program；
Step 3, MCU (data processor) reads bound signal；
Step 4, the bound signal read according to step 3 drives the light on and off of bound indicator lamp；
Step 5, reads RS485 bus datas and the data to reading are parsed, and analyses whether completely to be connected to a frame number
According to if not being connected to a frame data completely, step 4 being back to, if being completely connected to a frame data, into step 6；
Step 6, judges whether the data for receiving are correct, and return to answer signal to main frame；
Step 7, if data are correct, the indicator lamp work of driving rod position；If error in data, the work of rod position indicator lamp
Make state constant.
Rod described in the utility model position instruction device be used to indicating the insertion of HTGR reactor core control rod, lifting and its
The location of, the height and position of all control rods in HTGR reactor core can be intuitively shown by the present apparatus, give
Master control room operating personnel provide most intuitively status information input, facilitate operating personnel to see and look into reactor operation state and make phase
The control or decision-making answered.
In the utility model, removably (mainly pluggable mode) is sequentially arranged on device master for 24 indicating bars 2
