2. Query Protocol 2.1 Transport Protocol Reference Guide In the current implementation, TCP/IP is used as the transport protocol. TCP is a connection-oriented protocol that provides a reliable, in-order data transport layer with end-to-end checksums and flow control. This chapter lays the groundwork for the communication protocol between client software running on a remote computer and the V740 reader. The client software may be a database system, enterprise software, or user software.
2.2 Event/Query Protocol The client software can control the reader using RQL via TCP connection and can acquire data from the readers in two modes: 1) by requesting specific data or 2) by automatically receiving events. The two modes are discussed in further detail in the following subsections. In order to keep the protocol comprehensive and easy to use, we specify a small set of commands that allow the client software to fully configure the readers and exploit their capabilities.
2.2.2 General Observations, Commands, and Syntax We note that a reader behaves very much like database wherein each individual tag represents an entry in the database with a given set of attributes. Due to memory constraints of the reader, the system will remove entries from the database as they are queried. 2.2.3 Extended RQL Command Structure supported by the V740 Reader Extended Command Set for Data and Write, and Lock operations ID Read : Identify tags, including anti-collision.
[id1] [id2] .....[idn] 2.2.4 Detailed Command Structure The response includes the check code and ID. The first 4 digits are the check code, and the ID follows for the EPC1/1B protocols. 2.2.4.1 ID Read The client software would use the SELECT command to read IDs of tags. The SELECT command is for querying the tag population of the reader as well as static variables such as firmware version.
SELECT id FROM tag_id WHERE protocol_id='EPC1' AND antenna_id=1 AND (tag_id>=min_tag_id AND tag_id<=max_tag_id); SELECT id FROM tag_id WHERE antenna_id=1 AND protocol_id='EPC1' SET time_out=500; The command imposes a time out constraint of 500ms; i.e., the reader stops reading and returns all collected data after 500ms. The order in which specifying arguments are used is irrelevant. The default timeout is 250ms if none is specified.
The antenna arbitration algorithm is optimized to maximize the read rate of all the tags in the field. The time division for each antenna is determined automatically by the reader and cannot be specified by the user. e.g. if 10 EPC1 tags takes 20 ms per tag on average. With two antennas: minimum time_out = 10 x 20 x 2 x 2 = 800 ms. Note: It is caused by the following reasons that the difference between the time_out value and actual time required for reading. It spends 20 ms to switch protocols.
Table 2: Reader Internal Tag Data Table Schema -Tag Read Keyword SELECT Entry Table Arguments Range Example Value Comments id tag_id Hex String - 0xFEDCBA0 987654321 Requests the id (tag data) of the tag antenna_id tag_id Int - 2 Requests the antenna id used to read the tag protocol_id tag_id Int - 1 (EPC1/1B) Requests the protocol id of the tag read_count tag_id Int - 1 Requests the number of times a tag ID was read tag_id String - 1101973245.
2.2.4.2 ID Write – Writing data to tag • The UPDATE command is used to write new data to a tag. The structure of an UPDATE command is as follows: Example : To write tag data(tag_id) to a 64-bit EPC tag: UPDATE tag_id SET id=0x1234567890ABCDEF WHERE protocol=’EPC1’ AND antenna_id=1; UPDATE table_expression set_specification where_specification; The reader returns the tag_id if the write operation was successful.
1. • UPDATE tag_id SET locked=1, id=0x1234567890ABCDEF12345678 WHERE protocol=’EPC1’ AND antenna_id=1; ID Lock The UPDATE command is also used to lock data of a tag. This can be used to write '1' to 'locked' flag . The structure of an UPDATE command is the same as ID Write. The reader returns the tag_id the same way as 64bit tag. Example : To lock tag id of a 64-bit EPC tag: Note: The format of the tag data in the command must much the selected protocol or an error will result. (See section 1.
2. • Kill The UPDATE command is also used to initialize a tag. 3 parameters must be specified in SET Clause. The first is 'killed' flag, the second is password for the tag and the last is id of the tag. The structure of an UPDATE command is the same as ID Write. • Example : To lock tag id of a 64-bit EPC tag: UPDATE tag_id SET killed=1, password=0x88, id=0x1234567890ABCDEF WHERE protocol=’EPC1’ AND antenna_id=1; The reader returns the tag_id if the kill operation was successful.
3. • Set Password UPDATE tag_id SET password=0x88, id=0x1234567890ABCDEF12345678 WHERE protocol=’EPC1’ AND antenna_id=1; The UPDATE command is also used to set password of a tag. This can be used to set password. The structure of an UPDATE command is the same as ID Write. • Example : To lock tag id of a 96-bit EPC tag: The reader returns the tag_id the same way as 64bit tag.
4. Reader Control The client software can register a command with a cursor name to the reader. This section describes Cursors (Stored Procedures or Aliases ) and Reader settings. daemon to its initial state; that is, resets the reader, deletes cursors and clears memory. ii. Execution Commands stored as cursors can be executed in 3 ways as described below. i.
To run the query once at a specific time you use a milliseconds are spent with cursor idle(RF off). This syntax can be used for controlling the duty cycle of the command of the form: reader. For full reader utilization, ensure that the value SET trigger_time cursorname = 'starttime'; of time_out is less than the value of repeat, if not the cursor is executed continuously.
Example: The following example schedules reads to execute 1 time per second with an off time of 750ms, starting at a specific time: DECLARE cursor8 CURSOR FOR SELECT id FROM tag_id WHERE protocol_id='EPC1'; SET auto_time cursor8 = '2004-0122T12:43:08-05:00', repeat=1000; Note: Since time_out is not specified, the default time_out of 250ms is used. DECLARE SET auto_time RQL execution Response repeat start time time repeat (stop time) iii.
Keyword DECLARE Entry - Table n/a Arguments cursorname, Range Example Value Comments - cursor1 Defines the cursor name for the query. query FETCH - n/a cursorname - cursor1 Executes a cursor sends the data CLOSE - n/a cursorname - cursor1 Deletes a defined cursor RESET - n/a - - - Resets the reader, deletes cursors, clears memory SET tirgger_time n/a cursorname, - - Set a cursor to run at the specified time once.
2.2.4.3 Get Information The client software can get the information about the status of the reader. For example, firmware version and current time of the system. To get firmware version information, The format is as follows: SELECT entry FROM table_expression Table8 : Table Schema - Get Information Keyword SELECT FROM Entry Table Arguments Range Example Value Comments version Firmware String - 2.2.
2.2.5 Errors DECLARE cursor9 CURSOR FOR SELECT id FROM tag_id; If the reader is unable to execute a command issued by the client software, the reader issues an error message, which has the basic form: FETCH cursor10; Would result in the error message: Error error_code : string Error 0100: Cursor does not exist where error_code is an integer. Error codes and strings are documented in Table 6.
Invalid command in current mode Execute a command while another command is running on auto mode Error Codes Strings Explanation/Cause 0102 : Error performing query Tag is absent. ERROR_REMOT E Argument is illegal.
2.2.6 Protocol Specific Functionality and Parameter Settings While the standard ID_read and anti-collision searches are supported by practically all offered protocols, therefore no protocol-specific information is required to issue a RQL search. More specific commands, such as data_read and data_write require protocol specific information when formatting the query and interpreting the results. The tables below provide that information. 2.2.6.
2.3.3 Example 3 2.3 Examples Examples given in this chapter are provided as a guide for the user in determining suitability and does not constitute a warranty. Users must verify operation in their specific environment and application. To synchronize two readers see the following instructions. On Reader 1: DECLARE cursor_one CURSOR FOR SELECT id FROM tag_id WHERE protocol_id='EPC1' SET time_out=300; 2.3.
3. I/O This chapter describes how to use this function a function for external input/output control. The V740 Reader has an external input/output function on the RS232C connector; two for input and three for output. Following table is a terminal assignment. 00 : Normal 14 : Format Error OUT1 OUT3 IN1, IN2 Displays the status of output. 1 : ON / 0 : OFF Displays the status of input.
