具体实施方式 detailed description

图1为本实用新型阻抗测量安全启动装置的示意图。 1 a schematic view of the apparatus of the present invention is safe to start impedance measurement FIG. 该装置为测试系统中提供安全防护的功能,主要包括有:一系统控制单元1,通过检测所得的信号来控制电流产生器的输出值;一电流产生器2,可提供待检物一独立电流及电压,并可依照系统控制单元的要求输出所需的值;一电流检测器3,检测前述电流产生器所输出的电流状态,提供安全防护的功效。 The device provides security features for the test system, mainly comprising: a system control unit 1, controls the output value of the current generator obtained by the detection signal; a current generator 2 can provide analyte an independent current and a voltage, and outputs the desired value in accordance with the requirements of the system control unit; and a current detector 3, a current state of the detection output of the current generator, to provide safety protection efficacy. 前述各单元、装置形成一检测电路,该检测电路先行对待检物进行正式测量前的测量。 Each of the units, means forming a detection circuit, the detection circuit to be measured in advance before the sample was subjected to the final measurement.

在测试之前,为防止测试系统烧毁及人员的安全防护问题,系统控制单元1先要求电流产生器2产生较小的第一电流用以判断待检物4是否已连接在测试夹具上,该判断情况会持续反馈至系统控制单元1;当使用者将待检物4设置完成,且所有的电路都呈现待命状态时,此时系统控制单元1会检测到有待检物4的情况,随即输出一信号要求电流产生器2增加输出,产生符合测试待检物要求的第二电流、电压,进行测试动作;当测试时间结束或是设定的流程结束时,系统控制单元1即输出一信号要求电流产生器2恢复到第一电流,即微小电压、电流状态。 Prior to testing, to prevent security issues burning test systems and personnel, the system control unit claim 1 to the current generator 2 generates a first small current is used to determine whether the analyte 4 is connected to the test jig, the determination situation will continue feedback to the system control unit 1; when the user 4 is provided to be tested was completed, and all the circuits are rendered standby state, then the system control unit 1 detects the detected object 4 to be the case, then the output of a 2 requires a signal to increase the output current generator, generating a test analyte in line with the requirements of the second current, voltage, a test operation; or when the end of the test time setting process ends, i.e. the system control unit 1 outputs a signal required current generator 2 returns to the first current, i.e. a minute voltage and current status. 此时,若待检物4尚未移开时,系统控制单元1维持原先所提供的安全状态,也就是使电流产生器2输出微小的第一电流、电压的状态,不需进行下一步的测试动作,当待检物4移开后,即开始启动下一次的测试循环。 At this time, if not yet removed the analyte 4, the system control unit 1 originally provided to maintain a safe state, i.e., a current generator 2 outputs a first state of a minute current, voltage, without the next step of the test operation, after removal of the analyte 4, which has started the next test cycle. 另外,在待检物4两端连接一状态显示器5,使待检物4端的状态能够显示在状态显示器5上,通过电流检测器3配合操作员目视方式判断其测量的正确性。 Further, both ends of the analyte monitor 4 connected to a state 5, a state 4 the end of the analyte can be displayed on the status display 5, the operator with a visual mode 3 is determined by the correctness of the measured current detector.
