And sending the ammeter parameters to the detected intelligent ammeter or modifying the ammeter parameters of the detected intelligent ammeter, and reading the ammeter data of the detected intelligent ammeter.

The RS485 bus adopts a differential mode, and when sending '1', A-B>0.2V, when "0" is transmitted, B-A>0.2V, signal hold state, i.e., -0.2V<A-B<And 0.2V, because the stop bit of serial communication is '1', the idle state of the RS485 bus receiving end is kept to '1' in the normal communication state. In the electricity consumption information acquisition system, the communication of an RS485 bus is adopted as a half-duplex mode, an acquisition terminal sends an acquisition instruction, the instruction comprises an ammeter communication address, the collected ammeter hung below the acquisition terminal can receive data, and the instruction is complete and complete through judgmentWhen the correct address is correct, only the electric meter with the matched communication address waits for trPost-time response instruction, trThe time requirement is negotiated by the selected communication protocol, and the DL/T6452007 protocol gives a specific data range of 20ms<tr<500ms, and acquiring an idle time interval t between the transmission of a meter reading instruction by the terminal and the return frame of the electric energy metersAlso specified by the communication protocol negotiation, the DL/T6452007 protocol specifies Ts>20ms, some protocols negotiate as ts>33 bits, so whether receiving or sending has waiting time, when simulating meter reading test of the acquisition terminal, the waiting time must be customized to the test scheme according to the current communication protocol.
The communication gap or the polling time interval of the terminal waiting for acquisition can be calculated by taking the communication baud rate 2400, the byte format is a one-bit start bit, 8-bit data bit, one-bit even check and one-bit stop bit, the communication protocol requires that the data length does not exceed 200, and the header, the tail and the lead code are added, and 216 bytes are calculated in total, so the most ideal state is that the current bus is idle, the waiting time is 0, but the most of the time is the longest time for waiting for one frame: the Tw is 216 × 11/2400 is 0.99S, a case that multiple smart meters need to report when powered down at the same time needs to be considered, in the worst state, for example, 32 tables under the acquisition terminal all have power down, there is bus preemption in the communication gap, and if each table calculates reporting time in a manner of reporting a 6-byte active reporting status word: tr 22 × 11/2400 is 0.1S, the time to report of the last table: t ═ Tw +31 ═ Tr ═ 0.99+31 ═ 0.1 ═ 4.09S; in a practical environment, due to the stability of the communication system, a state such as timeout retransmission is involved, so that the time may be longer than T. In the test scheme, aiming at the active reporting scheme of the direct power failure of the seizing bus, the waiting time after the power failure can be set in an increasing mode according to the waiting time T, the final failure time is evaluated, and configurable parameters are involved in the test scheme: the method comprises the steps of testing times, capacitance charging time, waiting time, a sampling period, the number of sample tables, addresses of the sample tables, a communication baud rate and the like, wherein the total testing times are set to be 30 times (the times can be adjusted according to needs), the capacitance charging time is set to be full charging time 20s, the testing is started with the optimal state waiting time T (ts) being 20ms, Tw is increased progressively each time, after the increasing time reaches T, the increasing amplitude of each time is reduced to Tr until the measuring times are met or the communication power failure active reporting fails. The above operation is then re-cycled while taking into account the capacitor charging time as being in a non-full charge state.
Aiming at the test scheme that the active report adopts a polling mode of the acquisition terminal, only the acquisition period of the actual acquisition terminal needs to be considered, a general period unit is set according to min, the time is 1-15 min, for verification test, the test scheme adopts s as a unit and is used for better evaluating the failure time of the active report of the power failure of the ammeter, the acquisition period is similar to the setting of the waiting time in the first scheme, and the set is set in an increasing mode, and the test is carried out until the ammeter actively reports the failure or reaching set test times.
After the PC terminal test software configuration finishes various parameters of the test scheme, the parameters can be preset to the controller through the serial port, and the test of power failure active reporting is started through a command. After the controller receives the starting command, the controller starts to load parameters in the test scheme, and the controller firstly controls the test platform body to be electrified. And determining whether to preempt the bus according to the test scheme, wherein the idle state of the RS485 bus receiving end is kept to be 1 in the normal communication state, so that the bus can be preempted by enabling the bus state to be 0 or sending all 0 idle frame commands. And then, performing cyclic test according to the steps of controlling power supply/test table body to be powered on- > waiting for capacitor charging- > power down- > simulating test- > powering on- >. If a plurality of intelligent electric meters to be tested exist in the test, the intelligent electric meters are tested in sequence, and after the test of each meter is completed, the intelligent electric meters are stored into corresponding sample meter files for the PC end test software to read. And after the test of all the tested intelligent electric meters is finished, the controller automatically stops the test. The tested smart electric meter file stored in the controller can be read and deleted by the testing software at the PC end, and when the storage space is full, the tested smart electric meter file with the farthest date and time is automatically covered.
